Vitamin C isn’t just for immunity. Get five reasons why you need to load up on this supplement daily
While we usually associate vitamin C with its immune-boosting properties, the benefits of popping this vitamin daily extend well beyond cold and flu season. In fact, it probably isn’t given the credit it deserves so here are five new reasons to keep it in your daily supplement arsenal.
1. Reduce your risk of heart disease
Research from University of California, Berkeley, adds to the evidence that vitamin C supplements can lower concentrations of C-reactive protein (CRP), a central biomarker of inflammation that has been shown as a powerful predictor of heart disease and diabetes. For healthy, non-smoking adults with an elevated level of CRP, a daily dose of vitamin C (we recommend 1000-3000 mg per day, or until bowel tolerance) lowered levels of the inflammation biomarker after two months.
According to the researchers, the improvement is comparable to many other studies of cholesterol lowering drugs. While further research is needed, it’s certainly another good reason to keep your vitamin C in your supplement stash.
2. Improve your stamina at the gym
Vitamin C is required for the growth and repair of tissues in all parts of your body, making it a great idea to keep a bottle in your gym bag pre- and post-workout. One study, from the University of Wisconsin, found that 500 mg of vitamin C can offset workout fatigue.
Participants performed 60 minutes of exercise at the intensity of 50 percent of predicted maximal oxygen consumption. The vitamin C-supplemented group had significantly lower heart rates during exercise. In addition, perceived exertion and fatigue were both significantly reduced in the vitamin C group. The vitamin has also been shown to lower post-workout cortisol levels and improve recovery overall.
3. Feed your adrenals
Vitamin C is naturally highest in our adrenal glands. Research suggests stress can deplete our stores of the vitamin, meaning supplementation is a wise choice for extra protection during trying times.
Alabama researchers put laboratory rats under stress by immobilizing them for one hour a day over a three-week period. To check whether vitamin C would reduce the production of stress hormones, the rats were fed 200 mg a day. The study showed that vitamin C reduced the levels of stress hormones in their blood and also reduced other typical indicators of physical and emotional stress.
A German study subjected participants to stressors such as public speaking and math problems (certainly an acute stress for many). They found that cortisol and high blood pressure were significantly greater in those who did not receive a vitamin supplement.
4. Beat belly fat and improve insulin sensitivity
Vitamin C is one of the most widely used supplements today, but many of us don’t realize that it also plays a key role in our blood sugar levels.
A 2007 study published in the Indian Journal of Medical Research looked at 84 patients with type 2 diabetes who randomly received 500 or 1,000 mg of vitamin C daily for six weeks. The researchers discovered that the group supplementing with 1,000 mg experienced a significant decrease in fasting blood sugar, triglycerides, cholesterol (LDL) and insulin levels. The dosage group with 500 mg did not produce any significant changes
Vitamin C and glucose have a similar chemical structure. When both are high they compete with one another to enter the cells. If there’s more glucose around, less vitamin C will be allowed into the cells creating a deficiency. Not only is it important to keep your C levels up, it’s just as crucial to keep your blood sugar levels stable with a low glycemic diet.
5. Detox your bowels
We absorb vitamin C in the upper part of the intestine. Unabsorbed vitamin C continues into the lower bowel and causes watery stools or diarrhea. By taking large doses of vitamin C we can induce loose stools or a “levage” which is ideal during a detox (although timing is essential if you decide to do this). This can be helpful for improving elimination as well as determining what your daily dose of vitamin C should be. Here are the instructions:
