Many already know that vitamin D have an important role for bone health. However, who would have thought if a high dose of vitamin D was not really needed to protect bones.
This was found in a study published last Wednesday (27/7) in The New England Journal of Medicine . Studies have found that high doses of vitamin D are not necessary for a healthy group of middle-aged or elderly adults with no congenital bone disease or vitamin D deficiency.
As is known, vitamin D is needed by the body to fully absorb calcium and phosphorus from food.
In more detail, the study found, taking 2,000 IU of D3 supplements per day without calcium for more than five years was not able to reduce the risk of fractures when compared to the group taking a placebo every day. A placebo is a fake medicine pill that is given to a patient.
Study author Meryl LeBoff said her study was the largest randomized controlled trial of vitamin D supplementation in the United States. A total of 25,871 participants from 50 states took part in this study.
"Overall, the results from this large clinical trial do not support the use of vitamin D supplements to reduce fracture risk in those who are generally healthy," LeBoff said. CNN.
Does not apply to everyone
However, the results of this study did not apply to some groups. Among them are those who lack vitamin D, have low bone mass (osteoporosis), and have bone thinning disease. For this group, vitamin D intake is still required.
"It's important that osteoporosis patients be evaluated for the many factors that underlie osteoporosis," says LeBoff.
In addition, the study results also do not apply to the elderly group in nursing homes. LeBoff said this was due to certain factors that are common in nursing homes.
"They may rarely go out to get sun exposure, which is a major source of vitamin D," says LeBoff.
Vitamin D itself has an important role for the body. In addition to playing a role in maintaining the immune system, this vitamin also helps the body absorb calcium.
Adults up to age 70 are generally advised to get 600 IU or 15 micrograms of vitamin D per day. While those who are over 70 years old are advised to get 800 IU or 20 micrograms per day.(asr)
