What’s the story about certain kinds of vitamin C, calcium, etc.? Does it make any difference?
Because we live in a more complicated, modern world with chronic stress, pollution, etc., I always suggest wise supplementation for optimum health. The best supplementation is effectively comprehensive, properly balanced, and efficiently bioavailable. Some forms of some nutrients are simply more readily absorbed than others. Additionally, some forms of certain nutrients are easier on the digestive system than others, particularly in those with stomach sensitivity.
When it comes to food, you want the best your money can buy, and the same thing goes for supplementation. Different supplements (we’ll stick with “multivitamins” for now) fulfill their nutritional claims differently. Some forms of certain nutrients, generally the more bioavailable and stomach-friendly forms, are more expensive than less bioavailable or harsher forms.
