Dietary supplements are intended to supplement, not replace, the nutrients you get from your diet. They serve as an additional means of meeting nutritional needs.
Glucosamine is commonly used to support joint health and relieve symptoms of arthritis. It's often taken for joint pain and stiffness.
Calcium supplements can help prevent bone loss and are vital in reducing the risk of osteoporosis, especially in older adults.
Vegans often need a Vitamin B12 supplement because it is primarily found in animal products, and deficiency can lead to serious health issues.
Omega-3 fatty acids are known to support heart health by reducing inflammation and lowering triglycerides.
Folic acid is crucial during pregnancy as it helps prevent neural tube defects in the developing fetus.
Vitamin C is often taken to boost the immune system as it is known for its role in fighting off colds and infections.
Magnesium is often used to relieve constipation, as it can act as a laxative by drawing water into the intestines.
Lutein is a carotenoid that's often taken to support eye health and protect against age-related macular degeneration.
Vitamin C can enhance the absorption of non-heme iron from plant-based sources, which is beneficial for vegetarians potentially at risk of iron deficiency.
