Re: Natural versus synthetic
Search on D2 D3 bio-availability and see what you get
"Vitamin D3 increases the total 25(OH)D concentration more than vitamin D2. Vitamin D2 supplementation was associated with a decrease in 25(OH)D3, which can explain the different effect on total 25(OH)D."
Why on earth would I want to decrease my D3 levels by taking D2 instead? Are you a complete fucking moron? The sole purpose of taking D3 is to increase the level of D3, not decrease it.
