The 25,000 IU dose (approximately 7,500 µg) in this product far exceeds these values and is intended for short-term use under professional supervision. The UK safe upper level for preformed vitamin A from supplements is 1,500 µg per day. Taking more than this over a long period may lead to toxicity. Always consult a doctor or pharmacist before using high-dose supplements.\u003c\/p\u003e\u003ch2\u003eWhat Is Vitamin A?\u003c\/h2\u003e\u003cp\u003eVitamin A is a fat-soluble nutrient that plays a vital role in many bodily functions. Preformed vitamin A, known as retinol, is found in animal sources like fish liver oil, while provitamin A carotenoids come from plants.

Retinol is the active form of vitamin A, meaning it does not require conversion by the body. In contrast, beta-carotene from plants must be converted into retinol, and conversion efficiency varies. For individuals seeking direct and potent vitamin A, retinol is a reliable choice. The 25,000 IU dose provides a concentrated amount for those with higher needs or absorption concerns.\u003c\/p\u003e\u003ch2\u003ePotential Side Effects and Safety\u003c\/h2\u003e\u003cp\u003eVitamin A toxicity is possible when high doses are taken for prolonged periods.
