The truth about chronic disease and multivitamins

Vitamins are the organic compounds which are essential for normal growth and are required in small quantities in the diet because they cannot be synthesized by the body. Multivitamins are used to provide vitamins that are not taken in through the diet. Multivitamins are also used to treat vitamin deficiencies that are caused by pregnancy, poor nutrition, illness, digestive disorders, and many other conditions.Buy multivitamins online, the supplements contain minimum 10 vitamins or minerals with a wide range of doses.

Few patients might be facing a higher risk for vitamin deficiency and suboptimal vitamin status. Physicians might be unaware of common food sources of vitamins or may be unsure which vitamins they should recommend for their patients. Buy multivitamins online, an excess of Vitamin supplement is possible with supplementation, particularly for fat-soluble vitamins. Inadequate intake of multiple vitamins has been linked to some chronic diseases that include coronary heart disease, osteoporosis as well as cancer. Buy multivitamin online, because vitamins are the organic compounds which cannot be synthesized by humans and therefore must be ingested to prevent metabolic disorders. The elderly patients are particularly at risk for vitamins B12 and D deficiency, alcohol-dependent people are at risk for folate, thiamin deficiency, B6 and B12, and hospitalized patients are at risk for deficiencies of folate and other water-soluble vitamins.

Inadequate intake or subtle deficiencies in several vitamins are risk factors which cause chronic diseases such as cardiovascular disease, cancer, and osteoporosis. In addition, pregnancy or alcohol use may increase vitamin requirements. Buy multivitamin online, helps in supplying the adequate amount of vitamins to the body.

Chronic diseases are long-term medical conditions that are generally progressive like  heart disease, diabetes, stroke, and chronic respiratory problems. According to the estimation, the Chronic disease accounts for 35 million deaths worldwide where Cardiovascular disease and cancer comprise a major proportion of chronic diseases in both developed and developing countries. Along with cardiovascular disease and cancer, obesity-related diseases like type 2 diabetes, end-stage renal disease, and osteoarthritis are also becoming significant public health problems. The chronic diseases have a common risk factor with underlying pathologic mechanisms that may be modified by nutrients.

The biological effects of a nutrient are more dependent on its bioavailability.  Key factors which determine the bioavailability of micronutrients that are the chemical form in which the nutrient is presented to our intestinal absorptive surface, also, the presence of other competing chemicals in the intestinal lumen, intestinal transit time, the concentration of food constituents which bind to the nutrient and make it unavailable for absorption, and enzyme activity.

We should remember that a nutrient not only affects the absorption of other nutrients, also the transport, function, tissue uptake, and metabolism of other nutrients due to which a concurrent ingestion of several nutrients may result in synergistic, threshold or antagonistic effects as compared to a single nutrient.

The Food and Nutrition Board has established the tolerable Upper intake Levels(UL) for several nutrients. By definition, a UL is the highest level of daily nutrient intake turns out to provide no risk of adverse health effects to almost all people in the general population. Since the ULs were determined, several large-scale randomized controlled trials of vitamin/mineral supplementation have been completed. On adverse effects/events, an update of the data will help to evaluate the appropriateness of the ULs.
