It exists in two main forms: retinol (or retinal), known as preformed vitamin A, and provitamin A carotenoids, such as beta-carotene. Retinol is found in animal-sourced foods like liver, eggs, and dairy. This Klaire Labs SFI Health supplement provides preformed retinol derived from fish liver oil (Gadidae family), a natural and bioavailable source. Vitamin A contributes to the maintenance of normal vision, the normal function of the immune system, and the maintenance of normal skin* (EFSA-approved claims).\u003c\/p\u003e\u003ch2\u003eWhat makes this Vitamin A special?\u003c\/h2\u003e\u003cp\u003eUnlike beta-carotene, which the body must convert into retinol, this formula offers directly active retinol, ensuring efficient absorption. Each softgel capsule provides 25,000 IU (7,500 mcg RAE) of vitamin A, a high dose intended to meet specific needs under professional supervision. Fish liver oil is a traditional and concentrated source. Furthermore, this product is free from most common allergens: milk, casein, eggs, shellfish, tree nuts, peanuts, wheat, corn, and yeast. It contains no artificial colors, flavors, or preservatives. Developed in collaboration with healthcare professionals, Klaire Labs has been a trusted brand since 1969.*\u003c\/p\u003e\u003ch2\u003eBenefits of Vitamin A\u003c\/h2\u003e\u003cp\u003eVitamin A plays a crucial role in several physiological processes.

This supplement contains 7,500 mcg RAE (25,000 IU) per capsule, well above the recommended daily dose. Therefore, its use should be limited to specific cases under the supervision of a healthcare professional. The tolerable upper intake level for preformed vitamin A for adults is 3,000 mcg RAE per day (10,000 IU). Higher doses can increase the risk of toxicity. Its use without medical consultation is not recommended, especially for pregnant or breastfeeding women.\u003c\/p\u003e\u003ch2\u003ePossible side effects and precautions\u003c\/h2\u003e\u003cp\u003eExcessive consumption of preformed vitamin A can lead to hypervitaminosis A, a toxic condition manifesting with symptoms such as nausea, dizziness, headache, blurred vision, and liver damage. Especially important: high-dose vitamin A is teratogenic, so pregnant women or those planning to become pregnant should avoid exceeding the recommended dose (≤3,000 mcg RAE\/day). It can also interact with certain medications, such as oral retinoids.
