Detalles
What is Vitamin A?
Vitamin A is a fat-soluble nutrient essential for various bodily functions. 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).
What makes this Vitamin A special?
Unlike 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.*
Benefits of Vitamin A
Vitamin A plays a crucial role in several physiological processes. Based on EFSA-authorized health claims, we can highlight:
- Vision: Vitamin A contributes to the maintenance of normal vision. It is an essential component of rhodopsin, the visual pigment in the retina.
- Immune System: It contributes to the normal function of the immune system, helping to maintain the body's defenses.
- Skin: It helps maintain normal skin conditions, promoting cell renewal.
- Iron Metabolism: It contributes to normal iron metabolism.
- Cell Differentiation: It is involved in the process of cell specialization.
These benefits are supported by scientific evidence and recognized by European health authorities.
How much Vitamin A do I need?
The dietary reference intake for adults is 800-1000 mcg RAE per day (equivalent to approximately 2,666-3,333 IU). 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.
Possible side effects and precautions
Excessive 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. Please consult your doctor before starting to take this supplement.
How to choose the best Vitamin A supplement
When selecting a vitamin A supplement, consider the following factors:
- Form: Preformed retinol is more bioavailable than beta-carotene, especially useful for people with liver conversion issues.
- Dose: Adjust the dose to your individual needs. High doses require professional supervision.
- Source: Fish liver oil provides natural vitamin A along with other nutrients like vitamin D.
- Purity: Look for products free from allergens and artificial additives.
- Reputation: Brands like Klaire Labs, with decades of experience and collaboration with professionals, offer quality assurance.
Remember that food supplements should not be used as a substitute for a balanced and varied diet. Do not exceed the recommended daily dose. Keep this product out of the reach of children.
