Supplements are a multi-billion dollar industry 💊
Massive, largely unregulated, and marketed like everything works.
Here’s what actually has signal 👇
🟢 Actually works (in the right context):
Creatine → strength + cognitive signal
Protein → muscle + satiety
Psyllium → LDL + gut health
Vitamin D / B12 / iron → if you’re deficient
🟡 Mixed / situational:
Omega-3 → helps if triglycerides are high, not a magic heart pill
Magnesium → form matters (oxide ≠ glycinate)
Berberine → some glucose signal, not Ozempic
Collagen → modest at best
🔴 Where people get burned:
“Natural” ≠ safe
Red yeast rice = unregulated statin
Biotin can mess up lab results
Quality control is all over the place
🧠 The real mistake:
Taking supplements like a shopping list
instead of like medicine
In practice, the biggest wins are still:
sleep, diet, movement
Supplements = targeted, not default
