NOW Foods Vitamina A y D, 10000/400, 100 Cápsulas Blandas

What are Vitamins A and D, and why are they important?

Vitamins A and D are fat-soluble nutrients essential for the proper functioning of the body. Vitamin A, in the form of retinol, contributes to healthy vision, skin, and immune system. For its part, vitamin D (cholecalciferol) promotes the absorption of calcium and phosphorus, being key to maintaining strong bones and teeth. This NOW Foods supplement combines both in a convenient softgel, ideal for those seeking comprehensive nutritional support.

Health Benefits of Vitamin A and D

According to the European Food Safety Authority (EFSA), vitamins A and D have several scientifically recognized benefits:

• 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.
• Vitamin D: contributes to the normal absorption and utilization of calcium and phosphorus, to the maintenance of normal blood calcium levels, to the maintenance of bones and teeth under normal conditions, to the normal functioning of muscles, and to the normal functioning of the immune system.

Taking a supplement that includes both vitamins can be a convenient way to ensure adequate intake, especially during periods of less sun exposure or when the diet does not cover daily needs.

How much Vitamin A and D do you need? Recommended dosage

This product provides 10,000 IU (3,000 µg) of vitamin A (as retinol) and 400 IU (10 µg) of vitamin D per capsule. The recommended daily intake for adults is one capsule per day, preferably with a meal containing fat to improve absorption. It is important not to exceed the recommended dose, as high doses of vitamin A (especially in the form of retinol) can be harmful. If you are pregnant, breastfeeding, or taking other supplements, consult a healthcare professional before use.

Differences between forms of Vitamin A and D

Vitamin A can be found as retinol (of animal origin) or as beta-carotene (provitamin A, of plant origin). This product uses retinol, the form most directly usable by the body. As for vitamin D, there are two main forms: D2 (ergocalciferol) and D3 (cholecalciferol). D3, present in this supplement, is the form the body produces naturally with sun exposure and is considered more effective in raising blood levels. NOW Foods uses D3 from lanolin, a high-quality natural source.

How to choose the best Vitamin A and D supplement

When looking for a combined supplement, it is important to pay attention to the dosages, the vitamin form, and the brand's reputation. This NOW Foods product offers a balanced combination for adults who want to support their bone, eye, and immune health. The softgels facilitate ingestion and absorption. Always verify that the product is from a reliable brand and that it clearly indicates the amount of each vitamin per dose.

Possible side effects and contraindications

In general, this supplement is well tolerated when taken as directed. However, excessive doses of vitamin A (above 3,000 µg per day of retinol) can cause liver toxicity, digestive discomfort, or headaches. Very high doses of vitamin D can also cause hypercalcemia. Therefore, it is essential not to exceed the recommended daily dose. People with liver or kidney diseases or who are taking medications such as anticoagulants should consult their doctor before using this supplement.

This product is a food supplement and should not be used as a substitute for a balanced diet. Maintaining a varied diet and a healthy lifestyle is essential for overall health.
