Take Vitamin C Intake In Optimum Requirement
By Sam Cyrus

Vitamin C intake becomes an important thing refering to the optimum requirement. There are many researches of using the vitamin C for people with any disease.

Vitamin C intake also corresponds to healthy lungs. A research has shown that vitamin C can protect the lungs, and may lower the risk of developing chronic obstructive pulmonary disease. It's found that people with a high dietary of vitamin C intake have healthier lungs. The lung health will deteriorate at a slower rate over time with sustained levels of dietary vitamin C. The high  magnesium and vitamin C intake are associated with higher levels of lung function. People with a higher of vitamin C intake tend to experience less severe decline in lung function than those with a lower of vitamin C intake.

Vitamin C can  protect cells from harmful oxidation processes but may interfere with apoptosis by protecting genetically damaged cells from reactive oxygen species-dependent cell death. So, it needs to evaluate the association between vitamin C intake and apoptosis in normal rectal mucosa. It is frequency questionnaire of vitamin C intake obtained from a food , included both dietary sources and vitamin supplements.

People with adenomas must take control with vitamin C. There is an inverse linear association between apoptosis and total vitamin C intake for them. Similarly, individuals with adenomas in the highest quintile of total vitamin C intake were substantially less likely than those in the lowest quintile to have increased colonic apoptosis. Vitamin C was not significantly associated with apoptosis in adenoma-free patients. The study population has shown that high vitamin C intake is associated with reduced colorectal apoptosis among individuals with adenomas. Given that high apoptosis may lower colorectal cancer risk, vitamin C supplements may be contraindicated for patients with a history of adenomas.

It is a relationship between vitamin C intake and tissue concentrations. Many biochemical functions which occur in different tissues of the body rely on the vitamin C. The meta-analysis has also described the relationship between the vitamin C intake and plasma concentration. Plasma concentration may be a good indicator of an adequate vitamin C supply since blood is the vehicle for the vitamin C transport, . It has been suggested that the optimum plasma concentration of vitamin C is 50 µmol/L.

Even a few the above findings, it may suggest to take into account the need vitamin C in the clinical setting. It is necessary to determine optimum requirements of vitamim C intake.
