Vitamin A Benefits at a Glance
Vitamin A contributes to the maintenance of normal vision, the function of the immune system, and the maintenance of normal skin and mucous membranes. It also helps with normal iron metabolism and the process of cell specialisation. These health claims are authorised by the European Food Safety Authority (EFSA).
This NOW Foods supplement delivers 10,000 IU (3,000 mcg) of preformed vitamin A as retinyl palmitate per softgel, providing a potent dose in an easy-to-take form.
Types of Vitamin A: Retinol vs. Beta-Carotene
Vitamin A occurs in two main forms: preformed vitamin A (retinol and its esters) and provitamin A carotenoids (such as beta-carotene). This product contains retinyl palmitate, an esterified form of retinol that is readily used by the body.
Retinol is found in animal sources like liver, eggs, and dairy, whereas beta-carotene is present in colourful fruits and vegetables. The body must convert beta-carotene into retinol, a process that is less efficient. Therefore, retinyl palmitate provides a more direct source of active vitamin A, ensuring you receive the intended dose without relying on conversion.
How Much Vitamin A Should You Take?
The UK Reference Nutrient Intake (RNI) for vitamin A is 700 mcg per day for men and 600 mcg per day for women. The safe upper level from supplements is 1,500 mcg (5,000 IU) per day, as advised by the UK Committee on Toxicity. Each softgel provides 10,000 IU (3,000 mcg), which exceeds this upper level. Therefore, it is crucial to take only one softgel daily and not exceed the recommended dose.
Pregnant women should not exceed 3,000 mcg (10,000 IU) per day from supplements and are advised to consult a health care professional before use, as high doses can cause birth defects. Always consult a doctor before starting any new supplement regimen, especially if you are pregnant, nursing, or taking medication.

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 above the UK safe upper level, 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.
