NOW Foods Vitamina A, 25000 UI de Aceite de Hígado de Pescado, 250 Cápsulas Blandas

What is Vitamin A?

Vitamin A is a fat-soluble nutrient essential for numerous bodily functions. This NOW Foods supplement provides 25,000 IU of Vitamin A sourced from fish liver oil, a natural and bioavailable source. Each softgel capsule provides a concentrated dose that contributes to the maintenance of normal vision, skin, and mucous membranes, as well as the normal functioning of the immune system, according to EFSA-approved claims.

Vitamin A appears in two main forms in the diet: retinol (animal-derived) and provitamin carotenoids such as beta-carotene (plant-derived). This product uses retinol in palmitate form, directly usable by the body, making it an effective option for those seeking a guaranteed supply.

Benefits of Vitamin A

Vitamin A plays a key role in several physiological processes. According to the European Food Safety Authority (EFSA), the following health claims are authorised:

• Normal vision: Vitamin A contributes to the maintenance of normal vision.
• Healthy skin: It contributes to the maintenance of normal skin.
• Immune system: It contributes to the normal function of the immune system.
• Mucous membranes: It helps maintain normal mucous membranes.

Additionally, it is involved in iron metabolism and the process of cell specialisation. These effects are achieved with adequate intake as part of a balanced diet.

How much Vitamin A do I need?

Reference intakes for adults (according to EFSA) are 800 mcg of retinol equivalents per day (about 2,666 IU). One capsule of this product provides 25,000 IU, equivalent to approximately 7,500 mcg. This dose is higher than the recommended daily allowance and should be taken under supervision or as directed by the manufacturer. The recommended daily dose should not be exceeded.

For specific populations, such as pregnant women or individuals with liver conditions, it is recommended to consult a healthcare professional before use. The maximum tolerable intake for adults is 3,000 mcg/day of preformed retinol, so high doses require caution.

Possible side effects and precautions

Vitamin A in high doses can accumulate in the body and lead to toxicity if consumed in excess for prolonged periods. Symptoms of hypervitaminosis A include dry skin, headache, dizziness, and nausea. Therefore, it is essential to adhere to the indicated dosage.

This product is not recommended for pregnant or breastfeeding women without medical advice, as high doses can be harmful to the foetus. It should also not be combined with other supplements containing Vitamin A without supervision. If you are taking medication, consult your doctor.

Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of young children.

Frequently Asked Questions

What is the difference between retinol and beta-carotene?

Retinol is the active form of Vitamin A that the body can use directly, while beta-carotene is a precursor that must be converted into retinol. Fish liver oil provides preformed retinol, ideal for those with conversion difficulties or seeking an efficient source.

Can I take this supplement daily?

Yes, as long as the recommended dose of one capsule daily with a meal is respected. Exceeding this amount without professional supervision is not recommended.

Is this product suitable for vegetarians?

No. As it is derived from fish liver oil, it is not suitable for vegetarian or vegan diets. For these individuals, it is recommended to look for beta-carotene-based alternatives.
