NOW Foods Vitamina A 25000 UI, 100 Cápsulas (Paquete de 2)

What is vitamin A and why is it essential?

Vitamin A is a fat-soluble nutrient fundamental for the body. It plays a key role in vision, the immune system, and skin maintenance. NOW Foods presents this high-potency formula with 25,000 IU per capsule, ideal for those seeking a concentrated supply of preformed vitamin A (retinol). This pack includes two bottles of 100 softgels, offering a prolonged supply for your daily routine.

Benefits of vitamin A

Vitamin A contributes to several important physiological processes. According to the European Food Safety Authority (EFSA), vitamin A contributes to the maintenance of normal vision, the normal functioning of the immune system, and the maintenance of skin and mucous membranes under normal conditions. In addition, it is involved in the cell division process and iron metabolism. This supplement provides a significant dose of vitamin A to support these functions.

How much vitamin A do I need?

The dietary reference intakes for adults in the EU are 800 µg of retinol equivalents (RE) per day for men and 700 µg RE for women. One capsule of this product provides 25,000 IU, equivalent to 7,500 µg RE, a quantity much higher than the daily recommendation. Therefore, it is important not to exceed the dose indicated on the package and to consult a healthcare professional before use, especially if taking other supplements containing vitamin A.

Possible side effects and precautions

Excessive intake of preformed vitamin A can lead to toxicity, so the recommended daily dose must be respected. This product is not indicated for pregnant or breastfeeding women without medical supervision. Store in a cool, dry place, out of reach of children. Food supplements should not be used as a substitute for a balanced and varied diet.

How to choose the best vitamin A supplement

When selecting a vitamin A supplement, consider the form: retinol (acetate or palmitate) is the active and highly bioavailable form, while beta-carotene is a precursor that the body converts according to its needs. NOW Foods uses pure retinol in softgels for optimal absorption. This product is suitable for adults seeking a high intake, but a prior blood test is recommended if consumed for extended periods.

Frequently asked questions

Is it safe to take 25,000 IU of vitamin A daily?

The dose of 25,000 IU exceeds the tolerable upper intake level established by EFSA (3,000 µg RE/day for adults). Therefore, it should only be taken under professional recommendation and for short periods. It should not be combined with other vitamin A supplements without advice.

Does vitamin A help with night vision?

EFSA recognizes that vitamin A contributes to the maintenance of normal vision, including adaptation to darkness. However, a specific claim about "improving" night vision is not authorized. A severe deficiency can lead to problems adapting to dim light.

Can I get enough vitamin A from my diet?

Yes, sources such as liver, eggs, dairy products, and orange vegetables (carrots, sweet potatoes) are rich in vitamin A or beta-carotene. Supplementation is indicated in cases of diagnosed deficiency or increased needs.
