JAMA: Nearly 20,000 people have shown that vitamin D intake does not seem to reduce the risk of depression in adults!

August 9, 2020 // -- In a recent study published in jama, an international journal, scientists from Massachusetts General Hospital and other institutions conducted the largest study of its kind to date and found that vitamin D supplementation may not prevent depression in the elderly.
is a long-standing problem that may prompt some people to take vitamins.
researchers believe that vitamin D supplements may not have significant benefits and may not prevent depression or improve mood.
The study included more than 18,000 men and women aged 50 and over, half of whom received an average of five years of vitamin D3 (cholecalciferol) and the other half received a placebo matching the same time,' said Okereke, a researcher at Unsplash/CC0 Public Domain.
Vitamin D is sometimes referred to as the "sunshine vitamin" because the skin is able to naturally synthesize vitamin D when exposed to sunlight, after numerous studies have shown that lower levels of vitamin D (25-hydroxyvitamin D) in the blood are associated with an increased risk of depression in later life, but few large-scale randomized trials have been conducted to determine a causal link between the two, and now researchers have given a clear answer. 'One scientific problem is that we actually need a lot of research participants to determine whether a treatment can help prevent depression in individuals, ' explains okerke, a researcher at
.
the trial, called VITAL-DEP (Preventive Trial of End of Vitamin D and Ome-3 Depression, Depression Endpoint Prevention in The Vitamin D and Omega-3 Trial), is a randomized clinical trial of cardiovascular disease and cancer prevention in nearly 26,000 people in the United States.
researchers studied 18,353 men and women who did not show any signs of clinical depression at the beginning of the study, and then analyzed whether vitamin D3 intake protected participants from depression;
Final researcher Okereke said: 'It's not the time we start throwing away vitamin D, at least not without a doctor's advice, and some people taking vitamin D doesn't improve their mood; vitamin D is known to be vital to the health of the body's bones and metabolism, but randomized trials seem to question the other benefits of vitamin D that researchers speculate on.'
