Vitamin A is a catch-all term for a variety of fat-soluble compounds that are important to human health. Also known as retinol, some research suggests a lack of Vitamin A can negatively impact vision, and other research shows that maintaining adequate Vitamin A levels may help prevent age-related macular degeneration (1) (2). There’s also a bit of research that shows Vitamin A may be beneficial to the immune system (3) (4). Though many folks use Vitamin A supplements to treat acne, the American Academy of Dermatology actually recommends using topical retinol in treating your skin (5).
Found in a variety of foods, most folks following a well-balanced diet will ingest enough Vitamin A to meet the Recommended Dietary Allowance; Vitamin A deficiency is quite rare outside of developing countries (6). In supplement form, it’s most commonly found in capsules or tablets of varying strengths, either as beta-carotene or, more commonly, retinol. It’s worth noting that excessive Vitamin A in the form of retinol can be toxic with potential side effects, and the Food and Nutrition Board has established a daily Upper Limit of 10,000 IU (International Units) (7). Before introducing Vitamin A supplements to your diet, it’s important to consult with a medical professional.

Before adding it to your daily regimen, you should consult with a medical professional to insure that Vitamin A is right for you. When looking at the various types of Vitamin A supplements on the market, it’s important to consider a few distinguishing features.

For a frame of reference, the daily Recommended Dietary Allowance as established by the National Institute is 3,000 IU for men and 2,333 IU for women (6). It’s important to note, also, that the Upper Limit for daily Vitamin A intake is 10,000 IU. Since Vitamin A is fat soluble, excessive amounts of it can be stored in the body’s liver, and can have potentially toxic results.
Type of Vitamin A
Put simply, there are two basic types of Vitamin A: beta-carotene and retinol, also known as preformed vitamin A. Beta-carotene is largely found in leafy greens, vegetables, and fruits, while retinol is most often found in meat products and dairy. While some Vitamin A supplements are comprised of a mixture of beta-carotene and retinol, many will include just retinol.
Among retinol supplements, some will be sourced from fish oils, while others are chemically produced retinyl palmitate. Check the label to see what you’re getting, and as always, consult a medical professional before adding this to your diet.
Type of Pill
Depending on your personal preference, take a look at the type of pill each brand makes. Some will offer larger capsules, while some utilize small, dry tablets.
Not all Vitamin A supplements are vegan-friendly. If you follow a vegan diet, you’ll want to make sure you’re getting a supplement made from retinyl palmitate as opposed to fish oil.
Divide the total cost by the amount of pills or capsules in each container to figure out the price per serving of each offering.
