PubMed: The Source for Vitamin Science

PubMed: The Source for Vitamin Science

Vivioptal Vitamins / Thursday, February 28th, 2013

I ran across some interesting studies about vitamins recently on PubMed.gov, the science community’s central database for published scientific literature. Articles on PubMed are subject to peer review, meaning that experts have approved an article’s scientific validity before publication on the site. PubMed is the go-to source for the latest in scientific research.

When an article appears in PubMed, it has been carefully scrutinized. Each study’s methods of data collection and robustness of results and conclusions has been determined to be scientifically acceptable. Articles that don’t meet the highest international standards are rejected. Because articles on PubMed are peer reviewed, I know I can trust that they represent the very latest in scientific knowledge and understanding.

Science doesn’t try to prove, merely to observe, understand, and explain. As a result, our understanding about vitamins and minerals is always evolving. To be educated about what we put into our bodies, it’s important to continually review the scientific literature so we can stay current and continue to learn. Sites like PubMed make accessing the actual content of the scientific studies easier than ever before, so it is entirely within anyone’s ability to research the current state of scientific understanding.

Multivitamin use has sky-rocketed in the past two decades, and studies on their use have increased dramatically as well. On PubMed, a search for the term “multivitamin” returned 41 results in 1992 and 125 results in 2012. The difference in the number of results for the term “vitamin supplements” is even more dramatic, increasing from 79 results in 1991 to an astonishing 1,234 articles in 2011.

Let’s take a closer look at some of the most recent studies, and what they say about the benefits of vitamin use.

In a meta-analysis published in the Psychosomatic Medicine Journal of Biobehavioral Medicine in February 2013, scientists found that multivitamin supplementation reduced perceived stress, mild psychiatric symptoms, and anxiety in test subjects. While the term meta-analysis might sound scary, it’s not; it simply refers to the process of culling results from many separate scientific studies to look at broader, more global results. In this study’s case, taking vitamin supplements has a beneficial impact on the perceived stress and anxiety of the study participants.1

A study published in February 2013 in JHS: The Journal of Hand Surgery America showed that Vitamin D supplementation may help grip strength recovery in women with wrist fractures. Unlike the previously mentioned meta-analysis, the scientists in this study directly studied 70 women over the age of 50 who all suffered from distal radius fractures. As an important co-factor in calcium absorption, Vitamin D helps in the recovery of bone breaks.2

In another study published in February 2013 in The Journal of Clinical Endocrinology and Metabolism, scientists sought to establish why older African-American women have lower Vitamin D serum levels than older Caucasian women. They asked whether the phenomenon was due to lower skin production levels, lower absorption rates, or different metabolic rates. The study concluded that lower skin production rates in older African-American women causes lower Vitamin D serum levels, and that Vitamin D supplementation is effective in raising Vitamin D serum levels for that population.3

As you can see, taking vitamin and mineral supplements can be extremely helpful, and scientific studies continually reinforce this message. By checking in on the current state of scientific understanding regarding multivitamin supplementation, you too can stay up to date on the most recent studies.
