1. Vitamin A: your ally against cellular aging
Role : An antioxidant, it protects cells against oxidative stress, a key factor in aging.
Importance for seniors: Vitamin A requirements increase with age due to increased oxidative stress. A deficiency can accelerate cellular aging and lead to neurological problems.
Attention : Excess can cause hypervitaminose Awith harmful effects on health.
2. Vitamin B12: for a nervous and blood system in great shape
Role : Essential for the production of red blood cells, the proper functioning of the nervous system and the synthesis of DNA.
Issue : With age, the reduction in stomach acid limits the absorption of vitamin B12.
Consequences of a deficiency: Anemia, chronic fatigue, cognitive problems, numbness or tingling in the limbs.
3. Vitamin B9: essential for DNA and red blood cells
Role : Also called folic acidit contributes to the formation of red blood cells and the proper functioning of the nervous system.
Deficiency factors: Insufficient diet or interaction with certain medications.
To watch out for: A B9 deficiency can mask a B12 deficiency, leading to megaloblastic anemia.
4. Vitamin C: for a strengthened immune system
Role : Promotes the production of immune defenses, the formation of collagen and wound healing.
Risk among seniors: A deficiency can weaken the immune system and slow healing. In severe cases, it can cause scurvycharacterized by gum problems, bruising and anemia.
5. Vitamin D: the key to bone health
Role : Allows the absorption of calcium, reduces the risk of fractures and osteoporosis, while strengthening the immune system.
Issue : With age, the skin synthesizes less vitamin D and the time spent outdoors decreases, increasing the risk of deficiency.
Consequences : Bone fragility, fractures and reduced immune defenses.
6. Vitamin K: for coagulation and bones
Role : Essential for blood clotting and bone health.
Deficiency factors: Digestive pathologies or anticoagulant treatments can disrupt its absorption.
Risks: Excessive bleeding and decreased bone density.
7. Vitamin E: the powerful antioxidant
Role : Protects cell membranes from free radicals, supports cardiovascular health and slows cognitive decline.
Importance : By strengthening the immune system, it helps to compensate for age-related weakening.
How to prevent deficiencies?
Varied diet: Include foods rich in vitamins in your diet, such as fruits, vegetables, fatty fish and dairy products.
Food supplements: In case of proven deficiencies, consult a doctor to assess the need for supplements.
Sun exposure: Encourage regular outings to stimulate vitamin D production.
In summary: specific needs to monitor
Vitamins play an essential role in maintaining the health of seniors. Particular attention to their intake, combined with a healthy lifestyle, helps prevent deficiencies and improve the quality of life at any age.
