The effect of an oral supplement containing glucosamine, amino acids, minerals, and antioxidants on cutaneous aging: a preliminary study.

What Was Tested

The paper reports a study of Amino Acids and Antioxidants in the context of anti-aging & longevity, published as a randomized controlled trial.

Alterations in collagen, elastin, and glycosaminoglycans contribute to cutaneous changes seen in aging skin.

Who Took Part

The study group was 53 volunteers.

By PubMed's age tags, the people studied were adults and middle-aged adults, women only.

A randomized, controlled, single-blind study was conducted with 53 female volunteers who were supplied with an oral supplement containing glucosamine, amino acids, minerals, and various antioxidant compounds.

Hydration properties of the skin as well as textural analysis of the women's fine lines and wrinkles were assessed following 5 weeks intake of the oral supplement and results were compared with those of a control group of 12 individuals who did not take the supplement.

How the Study Was Run

The researchers set it up as a randomized and single-blind study.

Because people in this Amino Acids study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

Only one side, usually the volunteers, was kept unaware of whether Amino Acids was given.

What Was Measured

PubMed files the paper under topics including Amino Acids, Antioxidants, Drug Combinations, Glucosamine, Minerals, Photomicrography and Skin Aging.
