Believe it or not, vitamin C has benefits that extend far beyond simply boosting your immune system. In fact, it should take a permanent place in your supplement arsenal. Here are four great vitamin C benefits, including helping you handle stress, shed stomach fat and spiking your stamina.
Handle Stress Better
Vitamin C is naturally highest in our adrenal glands, and research suggests stress can deplete our vitamin C stores. So 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 milligrams a day, the equivalent of several grams a day for humans. The study showed that vitamin C reduced the levels of stress hormones in the 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 the vitamin supplement.
Slim down Stomach Fat
Vitamin C is one of the most widely used supplements today, but many of us donâ€™t realize that it plays a key role in our blood sugar levels. A study published in the Indian Journal of Medical Research (2007) looked at eighty-four patients with type 2 diabetes who randomly received either 500 mg or 1,000 mg of vitamin C daily for 6 weeks. The researchers discovered that the group supplementing with 1,000 mg of vitamin C experienced a significant decrease in fasting blood sugar, triglycerides, cholesterol (LDL) and insulin levels. The dose of 500 mg of vitamin C, however, did not produce any significant changes. Vitamin C is manufactured directly from glucose in the body and actually has a similar structure. Insulin is known to increase the cellular uptake of vitamin C. But if we know that vitamin C and glucose have similar chemical structure, what happens when glucose levels go up? They compete with one another to enter the cellsâ€”and if there is more glucose around, less vitamin C will be allowed in. Surprisingly, it does not take much glucose to create this cellular deficiency so not only is it important to keep your C levels up, itâ€™s just as crucial to keep your blood sugar levels stable with a low glycemic diet. And it certainly doesnâ€™t hurt your waistline.
Keep Your Heart Healthy
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 to be 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 lowered levels of the inflammation biomarker after two months, compared with those who took a placebo. According to the researchers, the improvement is comparable to many other studies of cholesterol lowering drugs. In fact, larger statin trials lowered CRP levels by about 0.2 milligrams per liter; and in this study, vitamin C lowered CRP by 0.25 milligrams per liter ( HYPERLINK “http://voices.yahoo.com/vitamin-c-may-lower-c-reactive-protein-important-4003775.html” http://voices.yahoo.com/vitamin-c-may-lower-c-reactive-protein-important-4003775.html ). While further research is needed, itâ€™s certainly another good reason to keep your vitamin C in your supplement stash.
Spike Your Stamina
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 for pre and post workout. One study from the University of Wisconsin found that 500mg of vitamin C can offset workout fatique. Participants performed 60 minutes of exercise at the intensity of 50% of predicted maximal oxygen consumption. The vitamin C-supplemented group had significantly lower heart rates during exercise, compared to the non-supplemented group. In addition, perceived exertion and fatigue were both significantly reduced in the vitamin C group.
