Vitamin D can be used as an anti-inflammatory agent in older people

Food supplements containing vitamin D and proteins stabilise chronic inflammations

The VUB research group Frailty in Ageing, led by Prof Ivan Bautmans, investigated, as part of the European PROVIDE study, the effects of food supplements on the immune system. For 13 weeks, 380 elderly people with reduced mobility were given either dietary supplements containing vitamin D and leucine-enriched proteins, or a placebo. The main finding of the study is that the chronic inflammatory profile increased in those older people who received a placebo. The dietary supplement with vitamin D and leucine was able to prevent this increase. The results were published in the scientific journal Aging Clinical and Experimental Research.

One of the characteristics of ageing is the occurrence of chronic low-grade inflammation. This slight but chronic increase in inflammatory substances in the bloodstream is caused by ageing processes in the immune system, an increase in fat mass and a sedentary lifestyle. Chronic low-grade inflammation accelerates the occurrence of chronic diseases such as cardiovascular diseases, diabetes, osteoarthritis, etc.

Chronic low-grade inflammation also has an influence on muscle strength and mass and increases the vulnerability of older people, thus reducing their independence. Preventing or curing chronic low-grade inflammation therefore contributes to healthy ageing.

The European PROVIDE study investigates the effects of dietary supplements containing vitamin D and proteins in elderly people with reduced mobility. Older people often lack vitamin D and proteins. Vitamin D can be found in fish, but it is also produced after exposure to UV sun exposure. In the winter, when there is little natural sunlight, a vitamin D supplement is often recommended. Proteins can be found in milk products, eggs, chicken white or legumes. The PROVIDE study has already shown, among other things, that the administration of vitamin D and protein supplements has a positive effect on muscle mass in older people.

About Press - Vrije Universiteit Brussel

Vrije Universiteit Brussel is an internationally oriented university in Brussels, the heart of Europe. By providing excellent research and education on a human scale, VUB wants to make an active and committed contribution to a better society.

The World Needs You

The Vrije Universiteit Brussel assumes its scientific and social responsibility with love and decisiveness. That’s why VUB launched the platform De Wereld Heeft Je Nodig – The World Needs You, which brings together ideas and actions based on six Ps. The first P stands for People, because that’s what it’s all about: giving people equal opportunities, prosperity, welfare, respect. Peace is about fighting injustice, big and small, in the world. Prosperity combats poverty and inequality. Planet stands for actions on biodiversity, climate, air quality, animal rights... With Partnership, VUB is looking for joint actions to make the world a better place. The sixth and last P is for Poincaré, the French philosopher Henri Poincaré, from whom VUB derives its motto that thinking should submit to nothing except the facts themselves. VUB is an ‘urban engaged university’, strongly anchored in Brussels and Europe and working according to the principles of free research.
