how to read supplement facts
Understand the Supplement Facts PanelThe Supplement Facts panel is the standardized section on every dietary supplement label, regulated by the FDA. It shows serving size, amount per serving, percent Daily Value (%DV), and lists the source of each nutrient. For example, magnesium should be listed as "Magnesium (as magnesium glycinate)" to tell you both the form and the elemental amount.Elemental Magnesium vs. Compound WeightElemental magnesium is the pure magnesium your body uses. Labels must state the elemental amount, not the weight of the whole compound. This is how you compare magnesium glycinate, citrate, or oxide to meet your daily needs. The FDA requires this declaration to help you understand exactly what you are consuming.Spot Quality and Avoid Red FlagsHigh-quality labels list each active ingredient with its own amount, not hidden in proprietary blends. Look for third-party seals like USP or NSF, clear expiration dates, and specific form names. Avoid vague phrases like "energy blend" or "miracle cure." These tips help you choose safe, effective supplements.
