Vitamin A Boost: Immunity & Energy in Easy-Swallow Capsules


Halfway through bottle at least they seem to work for me haven't tried many other high dose brands though I did try liquid though(well known brand) and didn't notice any difference. I take one or two a day. Easy to swallow no taste/smell for me. Almost gives a little bit of oomph, or extra energy for me which could be more test perhaps. Think this has improved immune function as well.


Vitamin Basics & Tips


Vitamin A plays a crucial role in maintaining vision, immune function, and skin health. This fat-soluble vitamin exists in two forms: preformed vitamin A (retinol, found in animal products like liver and eggs) and provitamin A carotenoids (like beta-carotene, abundant in carrots and spinach). The recommended daily allowance for adults is 900 mcg RAE for men and 700 mcg RAE for women.


Supplements, like the one reviewed, often contain retinol derivatives. High-dose supplements should be used cautiously, as excessive vitamin A can cause toxicity symptoms like dizziness or liver damage. Pairing supplements with dietary sources ensures balanced intake—sweet potatoes and kale are excellent plant-based options.


Vitamin A supports immune cells like T-cells and macrophages, explaining the reviewer’s perceived immunity improvement. Its role in cellular energy processes might contribute to the reported "oomph." Always consult a healthcare provider before combining supplements with medications, as vitamin A interacts with certain drugs like blood thinners.
