What people say about Vitamin D and energy
“I'm able to take about 400 ius of Vitamin D per day. Anything beyond that, and I become very angry/rageful and feel mentally terrible.”
“Part of it was taking D3+K2 every day. After sticking to this regimen I have lost 30lbs in 5 months and felt great.”
“I take 10 to 15k ug a few times a week with k2...giving me a sex drive like I'm a teenager. I wake with woodys every morning...I definitely get an increase in energy and motivation.”
“I was deficient in vitamin D per a blood test. I started taking enough to get my levels to normal and didn't notice a difference.”
