Supplements & Nutrients
Start with the question 'do I actually need this?' before the question 'which brand?' Most supplement use happens without baseline testing — meaning people supplement what they think they need rather than what testing would show.
The case for supplementation is correcting deficiency, not pursuing optimal upper-range biomarkers. A few supplements have genuine evidence for specific situations — vitamin D for deficiency, omega-3 for low-fish-intake diets, creatine for muscle preservation in older adults, CoQ10 for statin-related muscle symptoms. Much of the rest of the consumer supplement market is selling marketing rather than evidence. The Roadmap below sequences the evidence-backed cases first, names what to consider for specific clinical conditions, and is explicit about what to skip — including the longevity stacks and proprietary blends that dominate online wellness.
Step 1 (Built on consistent patterns across expert discussions)
Test before you supplement — and only supplement what you actually need
Most supplement use happens without baseline testing. Vitamin D, B12, ferritin (iron stores), magnesium status, and the omega-3 index can be checked through standard labs. Test, correct deficiency if found, retest at 3 to 6 months. Megadose protocols without testing produce a small risk of toxicity and a larger certainty of wasted money. Healthy adults with a varied diet, regular sunlight exposure, and no specific symptoms may have very little to supplement at all. Start with the question 'do I actually need this?' before the question 'which brand?'
