What vitamins should be taken with GLP-1?

GLP-1 receptor agonists have reshaped how many people manage glucose and weight, but they can also change how, when, and what you eat. This article explains which vitamins and other micronutrients may deserve extra attention while using GLP-1 therapy, how these nutrients work in the body, and how to support vitamin absorption with smart dietary support and timing. You will learn where the biggest nutritional gaps tend to appear, how to avoid supplement interactions, and when testing or professional advice can help. The goal is to help you make informed, evidence-aware choices about vitamins that complement GLP-1 therapy safely and effectively.

I. Introduction

A. Understanding the Role of Vitamins in Overall Health

Vitamins and other micronutrients are essential co-factors that power thousands of biochemical reactions in the body. They help convert food into usable energy, support the health of nerves and blood cells, regulate immune function, maintain bone and muscle integrity, and enable tissue repair. Most vitamins cannot be created in sufficient amounts by the body, so we rely on a balanced diet—and when appropriate, targeted nutritional supplements—to meet our needs. When intake dips below requirements or absorption is impaired, subtle symptoms such as fatigue, low mood, or reduced exercise tolerance may arise. Over time, low micronutrient status can influence metabolic health, bone density, immunity, and overall vitality.

B. The Rise of GLP-1 Receptor Agonists and Their Impact on Metabolism

Glucagon-like peptide-1 (GLP-1) receptor agonists enhance glucose-dependent insulin secretion, reduce glucagon release, slow gastric emptying, and influence appetite regulation in the brain. As a result, they help many individuals reduce blood glucose excursions and lower overall energy intake. These medications can be transformative for people living with type 2 diabetes or obesity. At the same time, the very mechanisms that make GLP-1 agents effective—decreased appetite, early satiety, delayed gastric emptying, and gastrointestinal side effects such as nausea—may change dietary patterns and, in some cases, micronutrient intake.

C. Why Nutritional Supplements and Vitamins Matter in Managing Glucose and Weight

Quality nutrients are the foundation for healthy metabolism. When energy intake is restricted, when dietary variety narrows, or when nausea reduces the desire to eat, the risk of micronutrient shortfalls can rise. Certain vitamins and minerals (e.g., B vitamins, vitamin D, magnesium, iron) are especially relevant because of their roles in energy production, neuromuscular function, blood formation, insulin signaling, and bone health. Thoughtful use of nutritional supplements may help bridge gaps, enhance nutrient synergy, and support vitamin absorption—particularly during periods of calorie reduction or digestive discomfort.

D. Navigating Health Symptoms, Supplements, and the Search for Optimal Support

It can be tempting to chase symptoms with individual supplements. However, symptoms alone don’t always reveal the root cause, and supplement interactions may reduce benefits if not chosen carefully. A structured approach—grounded in diet quality, symptom tracking, and when appropriate, lab testing—helps identify which vitamins are most relevant for you while taking GLP-1 therapy. The goal is not to take “more,” but to take the “right” support in the right way.

II. Core Explanation of the Topic

A. What Are Vitamins and Micronutrients?

Micronutrients include vitamins, minerals, and trace elements required in small amounts to maintain normal physiology. Water-soluble vitamins (B-complex and vitamin C) are not stored extensively and must be replenished regularly. Fat-soluble vitamins (A, D, E, and K) require dietary fat for optimal absorption and are stored in body tissues. Minerals such as magnesium, iron, zinc, iodine, and selenium support enzyme function, oxygen transport, thyroid activity, and antioxidant defenses. Adequate intake depends on both the diet and the body’s ability to absorb, transport, utilize, and excrete these nutrients.

B. How Do GLP-1 Medications Affect Nutrient Absorption and Metabolic Function?

GLP-1 receptor agonists slow the emptying of the stomach into the small intestine and can reduce appetite and overall calorie consumption. For many, this leads to weight loss and better glycemic control. From a nutrient perspective, the changes are indirect: slowing gastric transit may delay absorption of some orally ingested substances, and reduced hunger may decrease total food volume and diversity. Nausea or vomiting, if present, may further limit intake. While GLP-1 agents do not directly “strip” vitamins, these factors can cumulatively increase the likelihood of micronutrient gaps, especially if dietary variety and protein intake fall short.

C. The Importance of Nutrient Synergy and Dietary Support in Medication Regimens

Nutrients rarely act in isolation. Vitamin D facilitates calcium absorption; vitamin K helps direct calcium to bones; magnesium participates in hundreds of enzymatic reactions, including those involved in glucose metabolism. Vitamin C can enhance non-heme iron absorption, while B vitamins often work together in energy pathways. This nutrient synergy means that a thoughtful dietary pattern—adequate protein, colorful vegetables and fruits, fiber-rich carbohydrates, and healthy fats—can amplify the benefits of any supplements you choose, while reducing the risk of imbalance.

D. Common Effects of GLP-1 on Nutritional Status and Vitamin Levels

Research to date suggests that GLP-1 therapy primarily affects nutrition indirectly by changing appetite, food quantity, and meal timing. Potential downstream effects include lower intake of animal products (affecting vitamin B12, heme iron, and zinc), decreased consumption of dairy or fortified foods (affecting calcium and vitamin D), and reduced overall produce intake during periods of nausea (affecting vitamin C, folate, and potassium). Some patients report constipation or intermittent diarrhea, which can influence hydration and electrolytes. These are patterns to watch, not guaranteed outcomes—individual responses vary widely.

III. Why This Topic Matters

A. Addressing Common Concerns for Patients on GLP-1 Therapy

People often wonder whether GLP-1 medications cause vitamin deficiencies. The answer is nuanced: the drugs don’t directly deplete vitamins, but changes in appetite and digestion can alter eating habits and, in turn, micronutrient intake. Understanding which vitamins are most likely to be affected helps you make targeted, practical adjustments—through diet first and supplements when appropriate—to protect energy, mood, and metabolic health during treatment.

B. The Risk of Nutritional Deficiencies and Suboptimal Supplementation

Deficiencies can develop gradually and may remain unnoticed until they affect how you feel or function. Conversely, taking multiple supplements without a plan can create new issues by overshadowing nutrient synergy or causing supplement interactions (for example, excess zinc impairing copper balance or high-dose vitamin K interfering with warfarin). A careful, evidence-aware approach reduces the risk of both under- and over-supplementation.

C. Impact of Inadequate Micronutrient Intake on Treatment Outcomes

Micronutrient status can influence how you experience GLP-1 therapy. For instance, low magnesium may affect muscle function and sleep quality; suboptimal vitamin D status can affect bone and immune health; low B12 can influence energy and neurological function. While supplements do not replace medication, maintaining good micronutrient status can support overall well-being, adherence to dietary changes, and quality of life during treatment.

D. Enhancing Health Outcomes with Proper Nutritional Support

Combining GLP-1 therapy with a nutrient-dense diet and targeted supplements where needed may help you sustain progress. Investing in diet quality, hydration, and balanced macro- and micronutrient intake can reduce common hurdles like fatigue or constipation, enhancing day-to-day comfort and making it easier to maintain healthy habits.

IV. Related Symptoms, Signals, or Health Implications

A. Symptoms That Might Indicate Vitamin Deficiencies Post-GLP-1 Treatment

Symptoms of potential nutrient shortfalls are often non-specific. Possible signs include:

• Fatigue, low energy, or reduced exercise tolerance (possible iron, B12, folate, or magnesium concerns)
• Tingling in hands or feet, brain fog, or low mood (possible B12, B6, folate)
• Muscle cramps or poor sleep quality (possible magnesium, potassium)
• Frequent colds or slow wound healing (possible vitamin C, zinc)
• Dry skin, brittle hair or nails (possible biotin, zinc, iron)
• Bone or dental concerns over time (possible vitamin D, calcium, vitamin K)

These symptoms are not diagnostic; many factors can produce similar experiences. They simply flag areas for discussion with a healthcare professional.

B. Signals of Nutrient Imbalance or Poor Absorption

Changes in bowel habits, persistent nausea or vomiting, and a diet restricted to a very narrow set of tolerated foods may signal risk for micronutrient gaps. If you’re eating far less than usual or avoiding entire food groups for weeks, consider assessing your nutrient intake and discussing the need for supplements or lab tests with a clinician.

C. Long-Term Health Concerns Linked to Micronutrient Gaps

Chronic micronutrient insufficiency can affect bone mineral density (vitamin D, calcium, vitamin K), red blood cell production (iron, B12, folate), neuromuscular function (magnesium), and thyroid health (iodine, selenium). Sustained shortfalls may also influence mood, immunity, and recovery from exercise. While many people on GLP-1 medications maintain adequate status through diet, it is wise to stay attentive—particularly during periods of rapid weight change or persistent GI symptoms.

D. When Symptoms Are Not Enough: The Limitations of Guesswork

Because symptoms overlap across many conditions and nutrients, guessing can lead to inappropriate or excessive supplementation. Structured evaluation—dietary review, symptom tracking, and sometimes targeted blood tests—adds clarity. Such an approach helps you match the supplement to the need, use effective doses, and avoid unnecessary complexity.

V. Why Symptoms Alone Do Not Reveal the Root Cause

A. The Complexity of Nutritional Deficiencies and Underlying Causes

Low nutrient status can result from low intake, reduced absorption, increased needs (e.g., growth, high activity), medication effects, or health conditions affecting the gut, liver, or kidneys. Two people with identical symptoms may require very different strategies. For example, fatigue could reflect inadequate sleep, thyroid issues, iron deficiency, low B12, low folate, or a combination.

B. Factors Affecting Vitamin Absorption and Nutrient Utilization

Absorption depends on gastric acidity, pancreatic enzymes, bile flow, intestinal health, and the presence of food (particularly fat for fat-soluble vitamins). Certain medications and supplements can inhibit or compete for absorption (calcium with iron, zinc with copper, high-dose biotin with lab tests). GLP-1 therapy can delay gastric emptying, which may change the timing of absorption for some substances; this is often manageable by taking supplements with meals or at consistent times of day.

C. The Need for a Holistic Approach to Health and Nutrition

A whole-person approach emphasizes diet quality, physical activity, stress management, sleep, and social support. Within that context, supplements are tools—helpful when used for the right reasons, in the right amounts, and for the right duration. Focusing on the fundamentals first often reduces the number of supplements needed, while improving their effectiveness.

D. The Role of Comprehensive Nutritional Assessment

When uncertainty persists, clinicians may use blood tests such as 25-hydroxyvitamin D, ferritin and complete iron panel, vitamin B12 with methylmalonic acid (MMA) and homocysteine, folate, complete blood count (CBC), and in select cases zinc, copper, or red blood cell magnesium. Lab data are not required for everyone but can guide decision-making, especially if symptoms persist or dietary intake is very limited.

VI. The Role of Nutritional Supplements in Supporting Patients on GLP-1

A. How Supplements Can Address Micronutrient Gaps

Supplements can provide concentrated amounts of nutrients that are otherwise difficult to obtain during periods of low appetite or restricted intake. They help standardize dosing, allow for targeted correction of documented deficits, and can be timed around meals to enhance vitamin absorption. Used thoughtfully, they complement—not replace—a diverse, protein-forward, plant-rich dietary pattern.

B. Understanding Nutrient Synergy: Vitamins and Minerals Working Together

• Vitamin D and K: Vitamin D increases calcium absorption; vitamin K helps guide calcium into bones and away from soft tissues.
• Magnesium: A cofactor in vitamin D activation and hundreds of metabolic enzymes, including those supporting glucose handling.
• Vitamin C and Iron: Vitamin C can improve non-heme iron absorption from plant foods and supplements.
• B-Complex: B1, B2, B3, B6, B9 (folate), and B12 collectively support energy metabolism, red blood cell formation, and nervous system function.

C. Avoiding Supplement Interactions to Maximize Benefits

• Separate iron and calcium by several hours to improve absorption of both.
• High zinc (e.g., >40 mg/day long term) can reduce copper status; balance matters.
• Vitamin K can interfere with warfarin; medical guidance is essential if you use anticoagulants.
• Biotin at high doses may interfere with certain lab assays; inform your clinician before testing.
• GLP-1 agents rarely interact directly with vitamins, but delayed gastric emptying may alter timing—consistent routines help.

D. Enhancing Vitamin Absorption with Proper Dietary Support and Timing

• Take fat-soluble vitamins (A, D, E, K) with meals that include healthy fats.
• Magnesium glycinate or citrate may be better tolerated than oxide; consider evening dosing if it relaxes you.
• Iron is best on an empty stomach with vitamin C, but may be taken with food if GI upset occurs; avoid coffee/tea near dosing.
• Divide doses for better tolerance; small, consistent amounts often work well with GLP-1-related appetite changes.

VII. Who Should Consider Nutritional Supplements When Taking GLP-1?

A. Individuals with Dietary Restrictions or Poor Nutrient Intake

People who eat very small portions, skip multiple meals due to early satiety, or rely heavily on low-variety, ultra-processed options are more likely to benefit from targeted supplementation. Those following vegan or dairy-free diets may need extra attention to B12, iron, zinc, iodine, calcium, and vitamin D.

B. Patients with Symptoms of Vitamin Deficiencies or Other Signals

If you notice persistent fatigue, exercise intolerance, tingling in hands or feet, frequent infections, or gum bleeding, consider a nutritional review. While these symptoms are not specific, they can prompt constructive discussions with a clinician about diet, labs, or an initial trial of evidence-based supplements.

C. Those with Absorption Concerns or Digestive Issues

Chronic GI conditions, history of bariatric surgery, celiac disease, inflammatory bowel disease, or recurrent vomiting/diarrhea increase the risk of deficiencies. GLP-1 therapy can coexist safely in many of these contexts, but supplement strategies and forms (e.g., sublingual B12) may need tailoring.

D. Personalized Approaches: Consulting Healthcare Providers for Tailored Support

Clinicians can help prioritize which nutrients to test and which to supplement, how to time doses with GLP-1 administration, and how to adjust as your diet, weight, and lab markers evolve. Collaboration reduces uncertainty and minimizes trial-and-error.

VIII. Decision-Support: When Do Nutritional Supplements Make Sense?

A. Indicators for Considering Supplements (e.g., Deficiency Symptoms, Blood Tests)

• Documented low levels (e.g., low 25(OH)D, low ferritin, borderline B12 with elevated MMA)
• Prolonged low appetite or limited diet diversity
• Increased needs (e.g., athletes, pregnancy planning—under medical guidance)
• Persistent GI side effects limiting food intake

B. Situations Where Nutritional Support Enhances Treatment Outcomes

Though supplements do not replace any medical therapy, supporting micronutrient status can help you feel better day-to-day, potentially aiding adherence to dietary recommendations and exercise routines. Many individuals find that addressing nutrients like magnesium, vitamin D, and B12 helps maintain energy, sleep quality, and musculoskeletal comfort during weight-loss phases.

C. How to Choose the Right Supplements for Your Unique Needs

• Start with diet: Ensure adequate protein, produce, and healthy fats to cover most vitamins and minerals naturally.
• Pick evidence-backed essentials based on your intake and risks (e.g., vitamin D if sun exposure is low; B12 for vegan diets).
• Use appropriate forms and doses; avoid megadoses unless medically indicated.
• Reassess regularly; supplements may be temporary supports rather than permanent fixtures.

D. Integrating Supplement Use with Dietary and Lifestyle Changes

Supplements tend to work best when paired with lifestyle foundations—hydration, fiber, movement, and sleep. For example, magnesium plus evening relaxation practices may support better sleep; vitamin D with outdoor activity improves mood and circadian alignment; omega-3s complement a Mediterranean-style pattern rich in leafy greens, legumes, and fish.

IX. Practical Guidance for Maximizing Vitamin Benefits

A. Focus on Nutrients Most Affected by GLP-1 (e.g., Vitamin B12, Vitamin D, Magnesium)

While individual needs vary, the following nutrients commonly deserve attention during GLP-1 therapy because of changes in appetite, meal size, and food choices.

• Vitamin B12: Important for red blood cell formation, myelin integrity, and DNA synthesis. Low intake is more likely if animal product consumption declines. Oral cyanocobalamin or methylcobalamin in the range of 250–500 mcg/day, or 1000 mcg 1–2 times weekly, is commonly used; sublingual forms can help when absorption is uncertain. If you also take metformin, your clinician may monitor B12 more closely, as metformin can reduce B12 absorption in some individuals.
• Vitamin D: Supports bone health, muscle function, and immune activity. Limited sun exposure and low dietary intake are common. Typical maintenance intakes range from 1000–2000 IU/day of vitamin D3, adjusted based on 25(OH)D levels. Pair with healthy fats and consider synergy with vitamin K for bone support. Explore options thoughtfully via this resource on vitamin D, including sources and safety: vitamin D overview.
• Magnesium: Central to energy metabolism, nerve conduction, and muscle relaxation. Intake can fall if nuts, legumes, whole grains, and leafy greens decline during appetite suppression. Magnesium glycinate or citrate (200–400 mg elemental per day) is often well tolerated; adjust for bowel tolerance. For forms and considerations, see this guide: magnesium benefits.
• Iron: Essential for oxygen transport and energy. Low intake, menstruation, and reduced red meat consumption increase risk. Test before supplementing when possible (ferritin, iron studies). If needed, consider 18–28 mg elemental iron daily or every other day; take with vitamin C and away from calcium, tea, or coffee.
• Folate (B9): Involved in DNA synthesis and red blood cell production. Aim for dietary folate from leafy greens, legumes, and fortified foods; supplements (e.g., 400 mcg folic acid or methylfolate) may be considered in low-intake situations, especially with reduced vegetable consumption.
• Calcium and Vitamin K: Calcium needs can be harder to meet if dairy intake falls. Combine diet (dairy or calcium-set tofu, fortified alternatives) with vitamin D and vitamin K for bone support. For a deeper dive on vitamin K’s role in bone and blood health, see: vitamin K essentials.
• Vitamin C: Important for collagen synthesis, immune function, and iron absorption. Appetite changes may reduce fruit and vegetable intake, so many people consider 200–500 mg/day, ideally with food. If you focus on immune health and antioxidant support, this overview may help: vitamin C resource.
• Omega-3 (EPA/DHA): Supports cardiovascular, brain, and inflammatory balance. If fish intake is low, consider 500–1000 mg/day of combined EPA+DHA. Explore formulations here: omega-3 options. If using anticoagulants, seek medical guidance.
• Zinc and Iodine: Zinc contributes to immune and skin health; iodine supports thyroid hormone production. Be mindful of excess zinc (balance with copper if using higher doses) and avoid high-dose iodine unless advised by a clinician; most people meet needs through iodized salt or seafood.

B. Ensuring Optimal Vitamin Absorption through Proper Meal Timing and Composition

Because GLP-1 agents delay gastric emptying, consistent routines can smooth absorption. Consider these strategies:

• Anchor key supplements to your most reliable meal, even if small.
• Split doses (e.g., magnesium or vitamin C) to improve tolerance and reduce GI upset.
• Pair fat-soluble vitamins with meals containing olive oil, nuts, seeds, avocado, or fish.
• Schedule iron away from coffee/tea and calcium-rich foods; add a small source of vitamin C (citrus, berries, bell peppers) for synergy.

C. Monitoring and Reassessing Nutritional Status Regularly

Supplement needs typically change as your appetite and diet evolve. If you started GLP-1 therapy with robust diet quality, you may need only a few short-term supports; if meals remain minimal for months, more targeted supplementation or lab checks may be useful. Consider periodic re-evaluation of 25(OH)D, ferritin/iron studies, and B12/MMA if symptoms or intake patterns suggest risk.

D. Collaborating with Healthcare Professionals for Safe Supplement Use

Healthcare professionals can help you align supplements with any other medications, adjust timing around GLP-1 dosing, and interpret lab results. If you take anticoagulants, thyroid medication, or have kidney or liver conditions, professional input is especially important when adding or changing supplements.

X. Conclusion

A. Recap: The Importance of Vitamins and Nutritional Support with GLP-1

GLP-1 therapy can be a powerful tool for glucose control and weight management. While it does not directly deplete vitamins, changes in appetite, gastric emptying, and food choices may influence micronutrient intake. Prioritizing diet quality and considering targeted supplements helps you maintain energy, resilience, and metabolic support.

B. Moving Beyond Guesswork to Evidence-Based Nutritional Strategies

Symptoms alone don’t identify the exact deficiency. A measured approach—diet review, attention to nutrient synergy, and, when appropriate, simple blood tests—provides clarity. This reduces trial-and-error and minimizes the risks of both under- and over-supplementation.

C. Empowering Readers to Understand Their Health Profiles and Make Informed Decisions

Everyone’s biology and lifestyle are unique. By understanding how vitamins function, how GLP-1 therapy may shift your eating patterns, and how to enhance vitamin absorption with thoughtful dietary support, you can make choices that match your needs and preferences.

D. Connecting the Dots: Nutritional Supplements as a Key Element in Holistic Well-being

Supplements are not a cure or a replacement for medication, but they can be a valuable part of a holistic plan that includes balanced meals, physical activity, sleep, and stress management. With the right information and guidance, you can integrate vitamins and other micronutrients to complement GLP-1 therapy safely and effectively.

Key Takeaways

• GLP-1 medications don’t directly deplete vitamins, but appetite changes and GI effects can lower micronutrient intake.
• Focus on nutrient synergy: vitamin D with K and magnesium; vitamin C with iron; B vitamins working as a team.
• Common priorities include vitamin B12, vitamin D, magnesium, iron (if deficient), folate, and omega-3 fatty acids.
• Enhance vitamin absorption by pairing fat-soluble vitamins with meals and timing iron away from calcium, tea, and coffee.

Q&A: Vitamins and GLP-1 Therapy

1) Do GLP-1 medications cause vitamin deficiencies?

Not directly. However, reduced appetite, early satiety, and GI symptoms can lower dietary variety and total intake, which may increase the risk of micronutrient shortfalls. Paying attention to diet quality and considering targeted supplements helps mitigate this risk.

2) Which vitamins are most important to monitor while on GLP-1 therapy?

Vitamin D, vitamin B12, and magnesium are common priorities, with iron and folate considered based on diet and labs. Omega-3 fatty acids can also be helpful for those who rarely eat fish. Individual needs vary, so tailor choices to your intake, symptoms, and test results.

3) How does GLP-1 therapy affect vitamin absorption?

GLP-1 agents delay gastric emptying, which can change the timing of absorption rather than the total amount. Most people can maintain good status by taking fat-soluble vitamins with meals, splitting doses of sensitive supplements, and establishing consistent routines.

4) Should I take a multivitamin while using a GLP-1 medication?

A balanced multivitamin can be a reasonable safety net during periods of low intake, but it may not address specific needs like vitamin D or iron deficiency. Consider a multivitamin as a baseline and add targeted supplements only if dietary gaps, symptoms, or labs suggest they’re warranted.

5) Can vitamin K be taken with GLP-1 medications?

Yes, but if you use warfarin or similar anticoagulants, keep vitamin K intake consistent and consult your clinician. Vitamin K often complements vitamin D and calcium for bone health, especially when dairy intake is low.

6) Is magnesium helpful for GLP-1-related constipation?

Some forms, such as magnesium citrate, can soften stools, while magnesium glycinate is often used for relaxation without as much laxative effect. Start low, adjust to tolerance, and pair with fiber, fluids, and movement. If constipation is severe or persistent, consult a clinician.

7) Do I need to test vitamin levels before supplementing?

Testing isn’t mandatory for everyone, but it’s helpful for nutrients like iron, vitamin D, and B12 if symptoms persist or intake is limited. Objective data guide dosing and duration, reducing guesswork and the risk of unnecessary supplementation.

8) Are there supplement interactions I should be aware of?

Yes. Separate iron from calcium by several hours, avoid high-dose zinc without balancing copper, and be cautious with vitamin K if on warfarin. If you take thyroid medication, keep iron and calcium away from it by at least four hours. Discuss new supplements with your clinician.

9) How should I time supplements with GLP-1 injections?

Most people can take supplements with their usual meals regardless of injection timing. Because GLP-1 agents slow gastric emptying, consistency matters more than exact alignment with injections. If nausea is an issue, smaller, divided doses with food may help.

10) Can omega-3s support my health while on GLP-1 therapy?

Omega-3 fatty acids (EPA and DHA) support cardiovascular and inflammatory balance and may complement dietary changes. If you seldom eat fatty fish, consider 500–1000 mg/day of combined EPA+DHA. Seek guidance if you use anticoagulant medications.

11) What if I follow a vegan or mostly plant-based diet on GLP-1 therapy?

Pay special attention to vitamin B12, iron, zinc, iodine, calcium, vitamin D, and omega-3s (algal DHA/EPA). A well-planned plant-based diet can meet many needs, but supplements are often necessary for B12 and sometimes vitamin D and omega-3s.

12) How quickly will I notice benefits from supplementing?

Timelines vary. Some people feel differences in energy or sleep within weeks (e.g., with magnesium or correcting low B12), while bone-related changes from vitamin D/K are long-term. Reassess after 8–12 weeks and adjust based on how you feel and, when used, follow-up lab results.
