It occurs in two main forms: retinol, found in animal sources such as fish liver oil, and provitamin A carotenoids like beta-carotene, present in vegetables. This NOW Foods supplement offers 25,000 IU of retinol derived from fish liver oil, a highly bioavailable form that the body can use directly.\u003c\/p\u003e\u003ch2\u003eBenefits of Vitamin A\u003c\/h2\u003e\u003cp\u003eAccording to the European Food Safety Authority (EFSA), Vitamin A contributes to several key physiological functions:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMaintenance of normal vision:\u003c\/strong\u003e Vitamin A is an essential component of rhodopsin, a protein in the retina that allows for vision in low light.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eNormal functioning of the immune system:\u003c\/strong\u003e It helps maintain mucosal barriers and the activity of immune cells.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eMaintenance of normal skin and mucous membranes:\u003c\/strong\u003e It promotes cell renewal and tissue integrity.\u003c\/li\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eNormal iron metabolism:\u003c\/strong\u003e It participates in the mobilization of stored iron.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003cp\u003eThese benefits are supported by health claims authorized by the EFSA, ensuring that the information is accurate and reliable.\u003c\/p\u003e\u003ch2\u003eHow much Vitamin A do I need?\u003c\/h2\u003e\u003cp\u003eThe reference intake for adults in the European Union is 800 micrograms of retinol equivalents (RE) per day, which is approximately equivalent to 2,667 IU. However, this supplement provides 25,000 IU per capsule, a significantly higher dose. Therefore, it is important to note that the tolerable upper intake level for adults is 3,000 micrograms RE (10,000 IU) per day for retinol, although some individuals may require higher doses under professional supervision. Do not exceed the recommended daily dose indicated on the package. Consult a healthcare professional before taking high doses.\u003c\/p\u003e\u003ch2\u003eWhat is the difference between retinol and beta-carotene?\u003c\/h2\u003e\u003cp\u003eRetinol is the active form of Vitamin A found in animal-derived foods. It is directly absorbed and utilized by the body. Beta-carotene, on the other hand, is a precursor that the body converts into retinol as needed. Fish liver oil retinol is especially effective for those seeking a direct and potent source, while beta-carotene also acts as an antioxidant. This product contains pure retinol, ideal for specific supplementation.\u003c\/p\u003e\u003ch2\u003ePossible side effects and precautions\u003c\/h2\u003e\u003cp\u003eExcessive consumption of preformed Vitamin A (retinol) can lead to toxicity, with symptoms such as nausea, dizziness, dry skin, and, in the long term, liver damage. Pregnant women or those planning to become pregnant should not exceed 3,000 IU of retinol daily, as high doses can cause birth defects. This supplement contains 25,000 IU, so it is crucial not to take more than one capsule per day unless directed by a doctor. Keep out of reach of children. Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose.\u003c\/p\u003e\u003ch2\u003eHow to choose the best Vitamin A supplement\u003c\/h2\u003e\u003cp\u003eWhen selecting a Vitamin A supplement, consider the following aspects:\u003c\/p\u003e\u003cul\u003e\n\n\u003cli\u003e\n\n\u003cstrong\u003eForm:\u003c\/strong\u003e Retinol is more potent and direct; beta-carotene is safer in high doses.
