A well-formulated Mediterranean diet supplies most nutrients through whole foods, so supplements are optional rather than essential for most adults. Still, specific groups may benefit from targeted supplementation, most notably vitamin D, omega-3 fatty acids (when fish intake is low), and vitamin B12 for older adults. This guide reviews the evidence behind each supplement, explains who should consider it, and provides a practical checklist for choosing safe, quality-tested products.
Reishi (Ganoderma lucidum) supplements are among the most studied medicinal mushrooms, with the strongest evidence pointing to immune modulation and reduced fatigue, while heart-health, blood sugar, and anti-cancer effects remain supported mainly by lab and animal research. This guide grades each claimed benefit by the quality of human evidence, covers realistic dosages (1.5-9 g/day), forms, and timelines, and explains side effects, drug interactions, and liver-safety concerns. It also answers the questions other guides skip: whether daily long-term use is safe, whether reishi affects hormones or belly fat, and how to choose a quality supplement.
Most people can strengthen bone density with a short list of supplements: calcium, vitamin D3, and supporting nutrients like vitamin K2 and magnesium, but they only work when diet, dosing, and safety line up. This guide reviews the evidence behind each popular bone supplement, with recommended intakes, upper limits, absorption tips, and medication interactions. It also explains how to identify a quality product, when supplements are unnecessary, and which lifestyle changes deliver faster results than any pill.
EAAs contain all nine essential amino acids your body cannot make, while BCAAs supply only three of them — making EAAs the more complete option for muscle protein synthesis. That is why current research favors EAAs for muscle growth, with BCAAs mainly useful for reducing fatigue during long or fasted training sessions. For most people eating enough complete protein, however, neither supplement is strictly necessary. This guide breaks down the science, optimal dosing and timing, and exactly when each option is worth your money.

Fisetin is a plant flavonoid found mainly in strawberries that has attracted major scientific attention for its senolytic and antioxidant properties. Animal research suggests benefits for cellular aging, brain health, inflammation, and metabolic health, but human clinical evidence is still limited and ongoing.
