If you want to buy the supplements that I recommend, there is a supplement shopping guide that I can recommend.
I believe that it is very important to make sure that you know what you are taking. The main thing that I do is to ask a few questions before you start buying supplements. You need to know if the supplement is good, or if it is contaminated. If you don't know that you should not take this supplement, there is a simple solution. You can buy it from a reputable supplier. I am providing you with several excellent sources of vitamin C and B complex in supplements on this page. If you are unsure of the ingredients, there are good online stores who can tell you which one you are buying. This is just a sample of the types of supplements available for sale on my website. I have lots of samples and other supplements. The best and most complete supplement sources I have found on this site are: The Complete Guide To Dietary Supplementation - the definitive book on supplementing that has the most scientific information about supplements and which will show you the most reliable sources of these components.
