A booming practice, but not very framed
According to a survey carried out by public health France, Almost 60 % of people over 60 say they have already taken a food supplementmost of the time Without prescription or medical follow -up. The phenomenon is powered by vague but attractive messages: “strengthens immunity”, “supports joint function”, “fight against fatigue”.
The problem ? The effects of these products depend strongly on the health context of eachtheir current treatments and the quality of the supplements themselves. And seniors are particularly vulnerable to drug interactions or Micronutrient overdoses.
Turmeric: a plant in virtues, but not without danger
Used for centuries for its anti-inflammatory properties, turmeric is today present in many joint or digestive supplements. However, ANSES has identified a hundred reports of undesirable effects linked to its consumption in capsule or concentrated extract, of which 15 cases of serious hepatitis.
The formulations that combine turmeric and piperine (from black pepper) to increase the absorption are particularly problematic. Indeed, they modify hepatic metabolismwhich can cause interactions with many drugsin particular anticoagulants or treatments against diabetes.
ANSES therefore recommends a prudenceespecially for people under treatment, suffering from liver or elderly disorders.
Collagen: high expectations, little evidence
Another very popular product: the collagenpresented as a bulwark against skin aging, loss of tone and joint pain. If some studies suggest a modest improvement in the elasticity of the skin or the joint flexibilitythe evidence remains limited, often from work funded by manufacturers.
Moreover, Collagen ingested is broken down into amino acids like any protein. There is no guarantee that it will be reused in the form of collagen by the organization, or that it will target the desired fabrics.
The main risk? That of divert attention from truly effective approacheslike physical exercise or a balanced diet.
Magnesium: useful, but not systematic
The magnesium remains one of the most consumed minerals in the form of a supplement, especially for prevent fatigue, calm stress or limit cramps. It is true that some elderly people may present moderate deficits, especially in the event of digestive disorders or little varied food.
More supplementation should not be systematic : excess magnesium can cause diarrhea, nauseaeven Interactions with certain diuretic or antibiotic drugs. ANSES insists on the importance of Validate any supplementation by a healthcare professionalet to favor food intake First.

Favor naturalness, well -supervised
Taking food supplements is not trivial. It can be beneficial, but only in specific situations, validated by a healthcare professional et With regular follow -up. ANSES insists: “A supplement, even natural, can have pharmacological effects and interfere with treatment.”
