Reducing or removing the vitamin C in the D3+K2 supplement?
Original post in this thread

The D3+K2 supplement contains 225mg of Vitamin C. Given that there is some research showing that taking large doses of anti-oxidants such as Vitamin C (500mg/day, see below) interferes with anabolic muscle signaling, strength development and long term muscle growth, its intake should probably be controlled by people who exercise. Anyone eating a balanced diet is probably getting enough vitamin C already so supplementation is not really necessary.

I really wanted to buy D3+K2 supplement, but I'm afraid that the extra vit C may negatively affect my gains :). Is there any possibility of either reducing or removing it from the formulation?

What about my concern with excess Vitamin C being converted to unwanted oxalates?
Could you not use another anioxidant like rosemary extract or vitamin e?

Oxalate formation is not an issue for the vast majority of people, and a 225mg dose isn't large enough to worry about. I could look into the possibility of other antioxidants as alternatives, but then costs come into play. This was meant to be the most cost effective properly formulated D3/K2 on the market. If we start adding in more expensive ingredients as stabilizers, costs would have to increase.
