Is Vitamin C the Answer? By Mrs Vera West

     We have all long believed that vitamin C is enormously beneficial, but evidence has continued to accumulate over the years since the days of Linus Pauling with the point of view now is that vitamin C is even more important for health.

“Vitamin C deficiency is linked to a higher risk of mortality from cardiovascular disease (CVD), according to a recent review. Published in the International Journal of Molecular Sciences, the article also suggests that vitamin C may help regulate blood pressure, reduce arterial stiffness and decrease the amount of cholesterol in the blood.

The link between vitamin C and cardiovascular disease
Vitamin C, a water-soluble micronutrient, is hailed for its potent antioxidant effects, which allow it to reduce inflammation. This natural immune response, once dysregulated, contributes to the development of chronic diseases, such as CVD, cancer and macular degeneration. To understand the cardioprotective effects of vitamin C and the mechanisms underlying them, the researchers examined epidemiological and cohort studies on vitamin C and its role in CVD prevention. Most of the observational cohort studies that looked at the relationship between cardiovascular risk and vitamin C intake reported varying results. Still, all the studies agreed that having low plasma concentrations of vitamin C elevates a person’s risk of CVD. Some studies, on the other hand, focused on the effects of vitamin C on certain markers that help determine heart health. These include arterial stiffness, endothelial function (blood pressure regulation) and lipid profile. According to a review of randomized controlled trials (RCTs), vitamin C supplementation helps reduce arterial stiffness, which is caused by atherosclerosis. Atherosclerosis is a consequence of poor diet and physical inactivity, which triggers cholesterol buildup in the arteries. If left untreated, atherosclerosis can lead to intense chest pain, fatal blood clots and heart attack. In a separate study, researchers analyzed the effects of vitamin C on blood lipid levels and found that vitamin C supplementation leads to a small reduction in total blood cholesterol levels. The study involved participants aged 52 years and below. Vitamin C had also been found to increase the levels of high-density lipoprotein (HDL), or “good” cholesterol, in diabetics. (Related: Very high levels of HDL (good cholesterol) can increase your risk of heart attack and death, concludes study.) Meanwhile, other studies have found that vitamin C impacts both systolic and diastolic blood pressure in a positive way. Some studies even reported that vitamin C helps protect the endothelium — the tissue that lines the interior of blood vessels — from damage caused by oxidative stress.”

     The debate about vitamin C and cancer has also been going on for some time. Since the vitamin is relatively safe to take, I take a tablet every day, as well as having lemon drinks. You never know. Best be sure.
