A high whey protein, vitamin D and E supplement preserves muscle mass, strength, and quality of life in sarcopenic older adults: A double-blind randomized controlled trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc and Copper (Supplement), published as a randomized controlled trial.

The aim of the current study is to examine the effect of nutritional supplement containing whey protein, vitamin D and E on measures of sarcopenia.

Who Took Part

According to the abstract, 60 subjects were involved.

By PubMed's age tags, the people studied were middle-aged adults, older adults and people over 80, both men and women.

How the Study Was Run

In design terms this was a randomized, double-blind and placebo-controlled study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

As a double-blind Vitamin D, K2, Magnesium and Zinc study, the assignments were hidden from both participants and investigators until the end.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

What Was Measured

Topics PubMed links to this paper include Dietary Supplements, Muscle Strength, Muscle, Skeletal, Quality of Life, Sarcopenia, Vitamin D and Vitamin E.

The authors tagged it with the keywords Older adults and Whey protein.
