Types of Vitamin A: Retinol vs. Beta-Carotene
Vitamin A exists in two primary forms: preformed vitamin A (retinol and retinyl esters) and provitamin A carotenoids like beta-carotene. This product features retinyl palmitate, an esterified form of retinol that the body can use directly. Unlike beta-carotene, which requires conversion, retinyl palmitate provides a more efficient source of active vitamin A, ensuring you receive the intended dose without relying on enzymatic processes. Animal sources such as liver, eggs, and dairy contain retinol, while colorful fruits and vegetables provide beta-carotene.

What Is Vitamin A and Why Do You Need It?
Vitamin A is a fat-soluble vitamin that plays a critical role in maintaining the health of your eyes, skin, and immune system. It supports cell growth and the maintenance of tissues lining internal and external surfaces. This nutrient helps maintain normal vision, particularly in low light, and helps the body fight off infections by supporting immune function. Since your body does not produce vitamin A naturally, you must obtain it through diet or supplementation. This NOW Foods supplement provides 10,000 IU of preformed vitamin A per softgel in a convenient form.
Vitamin A Benefits at a Glance
-
Helps maintain healthy vision: Vitamin A is essential for the function of the retina and helps maintain eyesight, especially in dim light.
-
Supports immune function: It aids in the production and activity of white blood cells, which are critical for defending against infections.
-
Contributes to skin health: Vitamin A helps maintain healthy skin by supporting cell production and turnover.
-
Supports mucous membranes: It helps maintain the integrity of the tissues lining the respiratory, gastrointestinal, and urinary tracts.
-
Provides antioxidant support: Beta-carotene, a precursor of vitamin A, acts as an antioxidant to neutralize free radicals.
These benefits are recognized by nutrition experts, and supplementing with vitamin A can be especially helpful for individuals with limited dietary intake or increased needs.
How Much Vitamin A Should You Take?
The recommended dietary allowance (RDA) for vitamin A in Canada is 900 mcg RAE (3,000 IU) for adult men and 700 mcg RAE (2,333 IU) for adult women. The tolerable upper intake level (UL) for adults from preformed vitamin A is 3,000 mcg RAE (10,000 IU) per day. Each softgel provides 10,000 IU, which equals the UL. Therefore, it is important to take only one softgel per day as directed. Pregnant women should not exceed the UL because high doses can cause birth defects. Always consult a healthcare professional before starting any new supplement regimen, especially if you are pregnant, nursing, or taking medications.
Potential Side Effects and Safety Considerations
When taken as directed (one softgel daily), this vitamin A supplement is generally safe for most adults. However, because the dosage is at the upper limit, exceeding the recommended amount can lead to toxicity. Symptoms of vitamin A toxicity include nausea, dizziness, blurred vision, and liver damage. Long-term overconsumption can cause more serious issues like bone thinning. If you have liver disease or are taking medications that affect vitamin A metabolism, consult your doctor before use. This product is not intended for children unless directed by a physician. Store in a cool, dry place away from direct sunlight.
