Description
Vitamin A supplements offer a convenient way to maintain optimal levels of this essential fat-soluble vitamin, which plays a key role in vision by preventing conditions like night blindness. Available as retinol (from animal sources) or beta-carotene (from plant sources), vitamin A supports the immune system, helping protect against respiratory infections and promoting quicker recovery. It is also involved in maintaining healthy tissues in the internal organs and acts as a potent antioxidant, protecting cells from cancer and other diseases. Additionally, vitamin A supplements can help lower cholesterol, support skin health, and may reduce the risk of heart disease and stroke. Regular supplementation ensures adequate levels, especially when dietary intake may be insufficient.
When To Take It
Vitamin A is best taken with meals that contain fat for optimal absorption. If taken in oil form, it can be consumed at any time of day.
Synergy and Antagonism
Vitamin A works synergistically with vitamins B1, B2, B3, B6, B12, C, and E, as well as with minerals like calcium, potassium, magnesium, phosphorus, manganese, selenium, and zinc. These nutrients support healthy vision, immune function, and skin health. Vitamin A may have antagonistic interactions with vitamin D, calcium, copper, sodium, and selenium, as excessive levels of these nutrients can interfere with its absorption or function.
