New research recommends a higher intake of vitamin C due to its role in preventing cardiovascular disease, cancer, and cataracts. Studies show that increased levels of vitamin C can reduce risk factors associated with these conditions, making it essential for overall health.
A new observational study published in JAMA found a significant correlation between low vitamin C levels and high blood lead levels among Americans. The study analyzed data from over 19,500 Americans and revealed that about half of one percent have elevated levels of lead in their blood.
Research by Oregon State University's Linus Pauling Institute found that vitamin C does not interact with metals like iron in a way that causes pro-oxidant effects. Instead, it reduces oxidative damage and is linked to improved health outcomes, including reduced risk of cancer, heart disease, and aging.
Researchers found that patients with high vitamin C levels had improved blood vessel function, reducing the risk of unstable angina pectoris. A 500 milligram daily supplement of vitamin C may also be beneficial in improving blood vessel dilation and reducing heart attack risks.
Researchers at Memorial Sloan-Kettering Cancer Center found that growth factors, known for controlling immune cell production, also increase the ability of immune cells to take up vitamin C. This discovery sheds light on the connection between vitamin C and the immune system, showing how growth factors can boost immune function.
Researchers at Memorial Sloan-Kettering Cancer Center found a way to increase vitamin C levels in the brain by crossing the blood brain barrier. They achieved this by injecting dehydroascorbic acid, which is converted to ascorbic acid in the brain.
A study published in the American Journal of Clinical Nutrition found that taking vitamin C supplements for over 10 years significantly lowers the risk of lens opacities and subsequent cataracts in older women. Researchers discovered a 77% lower prevalence of early and 83% lower prevalence of moderate lens opacities among women who use...
Researchers found that people with porphyria, a group of disorders causing chemicals to accumulate in the body, have low vitamin C levels in their blood. Increasing dietary levels of vitamin C may help prevent porphyrin accumulation and skin damage.
A population-based study found that higher vitamin C levels were associated with lower oxidative stress and a reduced risk of cell damage. The study involved 393 participants and measured the actual level of vitamin C in their blood serum.
Researchers found that HIV-infected immune cells take in more vitamin C and glucose than healthy counterparts, but extremely high levels are toxic. This study provides a foundation to understand the relationship between vitamin C, HIV infection, and cell metabolism.
A new study by Cornell University researchers reveals that plants require vitamin C to withstand environmental stresses, such as high ozone levels and ultraviolet radiation. This finding has significant implications for improving crop foods with low vitamin C content, which can help address nutritional deficiencies in humans.
Researchers found that taking vitamins C and E before a high-fat meal can prevent impairment of blood vessel dilation. The study suggests that vitamins may influence minute-by-minute changes in blood vessels that lead to heart disease. Vitamins may blunt the process by releasing nitric oxide, which allows vessels to dilate.
