Vitamin D3 + K2 (MK-7)

Vitamins & Minerals

Adults50+ / Veteran

Grade A — Strong Evidence Grade

MOOP's Take

D3 deficiency is epidemic in men over 40, especially veterans who spent years in garrison or shipboard environments. It's foundational for testosterone, immune function, and mood.

My Protocol

TimingAM with fat (fat-soluble — take with eggs, olive oil, or avocado)

DoseD3: 4,000 IU / K2: 100–200 mcg MK-7 form

NotesEvery morning with my first meal. Non-negotiable — especially at 47 and in the mid-Atlantic where sun exposure is inconsistent. K2 directs calcium away from arteries and into bones, so if you're taking D3 without K2 you may be doing more harm than good.

What It's For

💪 Coach Arnie

Fat-soluble — if you're taking this in a fasted state you're probably absorbing 40-50% less than you should be. Eat first.

🩺 Doc Hartley

His 2018 labs showed no D level tested — most likely deficient. At 47, optimal range is 60–80 ng/mL, not the 30 ng/mL 'normal' threshold. MK-7 form of K2 has a longer half-life than MK-4. Don't skimp on this one.
