Food supplements, to take or leave after 60 years?
After 60 years, we can sometimes do without
True. This is the case for vitamin D, which is naturally produced less with age. After 60 years, more than half of women are deficient and many doctors believe that dietary supplements should be systematic, especially because of their role against osteoporosis and sarcopenia (muscle wasting). Although not universally accepted, omega-3 supplementation is often recommended to preserve cognitive functions, especially if you eat few oily fish.
Better to avoid those for osteoarthritis
True and false. ANSES (National Agency for Food Safety, Environment and Labor) has reported adverse effects (including digestive or hepatic disorders) with glucosamine-containing articular supplements and / or chondroitin. But these incidents remain rare (about ten cases in nine years) and moderate. These products are still not recommended as a precaution if you are diabetic, asthmatic, allergic to crustaceans (for glucosamine), if you take certain anticoagulants (anti-vitamin K) or if you have to control your intake of sodium, potassium or calcium, because they provide a significant amount.
Buying them on the Internet is dangerous
True. Apart from online sales sites of reputable laboratories, there is a real risk of counterfeiting, impurities or substandard ingredients, especially with Chinese or American products. Also beware of attractive specials and supplements much cheaper than elsewhere, they are often synonymous with scam. Privilege purchases in pharmacy, drugstore and organic supermarket, regulated by the European Union.
Do not take more than one at a time
True and false. It is indeed likely to find identical nutrients (especially in multivitamin mixtures) and thus an overdose. Vitamin C can, for example, be oxidative if consumed in excess. Above all, some ingredients may interact with each other or with medications (omega-3 and anticoagulants, or vitamin B3 with treatments for blood pressure or cholesterol in particular). That is why it is always better to take a medical opinion before multiplying supplements.
