Coffee and Caffeine FAQ

Did you mean 1000%? 1000% is only 10x the RDA. I haven't seen a multivitamin that contains even 50% of the RDA of either calcium, or magnesium. It's better to take a multimineral and a multivitamin. I suggest cal/mag/zinc tablets with vitamin D because these minerals and vitamins work together. Vitamin K is usually lacking from multivitamins too. I found one calcium magnesium supplement that had vitamin k and vitamin D at Costco. Vitamins K and D are both important for bone health. You can get vitamin K from leafy green vegetables. If you don't eat leafy green vegetables, then you need a vitamin k supplement.
