Frequently Asked Questions
What supplements are most evidence-based?
Strong evidence supports creatine, vitamin D (if deficient), omega-3s, and protein. Many other supplements lack robust research support.
When should I take supplements?
Fat-soluble vitamins (A, D, E, K) with meals. Creatine anytime consistently. Caffeine 30-60 min pre-workout. Magnesium and zinc before bed.
Can supplements interact with each other?
Yes. Calcium blocks iron and zinc absorption. Take them separately. Some supplements also interact with medications.
Do I need supplements if I eat well?
Most nutrients can come from food. Supplements may help fill gaps but cannot replace a balanced diet. Focus on food first.
