General health supplementation with strong evidence base and low risk profile

"I will happily take vitamin D. I know there's no real downside risk unless I overdose. I know it has a lot of benefit. I know there's evidence to it."

Hormone health, immune function, general health optimization

"Vitamin D, 5,000 to 10,000 IUs per day. Most people are underdosing vitamin D. I can see my bloods getting better when I take 5,000 as opposed to 3,000 IU of vitamin D and I'm not changing anything else. So vitamin D — and I get sunlight."
