What Does Vitamin C Actually Do?

We see vitamin C a lot these days, mostly in the context of cold prevention (or treatment). Vitamin C is a water soluble vitamin found in certain foods and added as fortification to others. Humans don’t synthesize vitamin C, so it’s essential that we include it in our diet.

Roles of Vitamin C

Vitamin C is essential for the synthesis of collagen, L-Carnitine, and some neurotransmitters, and is also involved in some protein metabolism. It is also an antioxidant thought to help regenerate other antioxidants like vitamin E, helps the body absorb non-heme iron (meaning iron from plant based foods), and plays an important role in immune function. Vitamin C deficiency results in scurvy (often linked to pirates and sailors, who went long periods without fresh produce), which causes fatigue and connective tissue weakness.

Collagen synthesis and immune function are the most notable and widely recognized roles for Vitamin C. Collagen is the most abundant protein in the body, found in muscle, bone, and tendons among other important tissues.

Buying Supplements from CVS? You’re Probably Getting Hosed

Walgreens, GNC, Walmart, and CVS don’t always sell supplements. But when they do, they’re fake. Oh wait, they actually DO always sell supplements. And they’re still fake, well maybe some of them. At least according to New York’s Attorney General (aka my new favorite politician), who is going after these fraudsters. My previous rants on supplements and GNC have focused on the fact that a teenager making minimum wage with no nutrition experience or education can advise you on dietary supplements that are very poorly regulated by the FDA if he happens to work at GNC or a similar outlet.

This time though, the focus is on the fact that not only did these four retailers try to sell you poorly regulated crap you don’t need, they also lied about the crap that was in it! According to a write up in the New York Times:

“The authorities said they had conducted tests on top-selling store brands of herbal supplements at four national retailers — GNC, Target, Walgreens and Walmart — and found that four out of five of the products did not contain any of the herbs on their labels. The tests showed that pills labeled medicinal herbs often contained little more than cheap fillers like powdered rice, asparagus and houseplants, and in some cases substances that could be dangerous to those with allergies.”

In addition, some supplements at Target also tested negative for the herbs on their label. Basically, those ginkgo baloba pills you bought for “vitality” were really powdered garlic and powdered rice. For that I could have just made you some stir fry!

The New York State AG sent cease and desist letters to those four retailers. And of course industry reps are trying to pass this off as “bad practices from fringe companies”. Sorry guys, CVS is not a “fringe” company.
