Vitamins are required in minimum amount each day for the proper functioning of the body and general well-being. Apart from providing the groundwork for the body to grow and develop, they?re also responsible for functions such as immunity, metabolism and digestion. The U.S National Library of Medicine states that a balanced diet consisting of variety of fruits and vegetables is recommended for fulfilling daily vitamin needs.
People who can?t meet their daily vitamin needs from foods alone may require dietary supplements. For example, if someone isn?t getting the minimum amount of vitamin D each day, he/she can opt for a multi-vitamin supplement or a single vitamin supplement like?Pureformulas Vitamin D3.
Nutritionists, scientists and doctors keep on researching more about vitamins. Here are some new theories that have surfaced in recent times;
New Research?
1.?Vitamin D lowers risk of dying in older adults
Ellen Smit from Oregon State University, US, conducted a study last year; 4300 older adults above 60 years of age were part of the study and they were divided in different groups based on their Vitamin D levels. The group with low Vitamin D levels were more likely to be frail. The study revealed that older adults whose Vitamin D levels were lower had a 30 percent higher chance of facing death earlier compared to adults with high Vitamin D levels.
2.?Vitamin D supplements may help in reducing cardiovascular disease
James Vacek carried out a research with Kanas-based researchers, in which they noted Vitamin D deficiency in the group of people they examined was associated with a higher risk of cardiovascular diseases, while Vitamin D supplements were associated with 61 percent increase in chances of survival in the study population. The study concluded that vitamin D supplements may help people to live longer.
.?Vitamin B3 may be able to fight off antibiotic-resistant staph infections
Dr. Gorge Liu from Cedars-Sinai Medical College in Los Angeles California conducted study with his colleagues. They found Vitamin B3, when taken in doses that were far higher than a dose would be for a normal diet, increased the strength of immune cells to eliminate bacteria by 1,000 times in just a few hours. The effect was conducted on human blood samples. The result of the study indicated that nicotinamide or Vitamin B3 may have the ability to kill staph infections (which are antibiotic resistant) that have killed thousands worldwide. Supplements can aid in higher Vitamin B3 dosage.
Conclusion
The studies show the importance of vitamins and supplementing in case of deficiency. Everyone should try to eat 5 servings of fruits and vegetables for meeting their daily vitamin needs, and complement the diet with supplements to avoid any deficiency. Doing so will promote a healthy lifestyle.
