I've been deep in the health optimization space for years and these are the 3 biggest dosing mistakes I see constantly:

1. Magnesium — wrong form, wrong time

Most people take magnesium oxide because it's cheap. It has ~4% bioavailability. You're literally flushing money. Switch to magnesium glycinate (for sleep) or magnesium L-threonate (for cognition). Take it 60-90 min before bed, not with meals.

2. Vitamin D — no K2, no cofactors

Taking 5,000 IU of D3 without K2 is asking for calcium to deposit in your arteries instead of your bones. Always pair D3 with K2 (MK-7 form, 100-200mcg). And get your blood levels tested — most people need more than they think.

3. Omega-3s — underdosed and oxidized

The standard fish oil capsule gives you maybe 300mg of EPA+DHA. Research-backed doses for inflammation and cognition start at 2-3g combined EPA+DHA daily. And check the manufacture date — oxidized fish oil does more harm than good.

These are basics, but getting them right changes everything. Inside Peak Health Academy, I break down the full protocol stacks I use and update them monthly based on new research.
