NOW Vitamin A 25,000 IU, 100 Softgels (Pack of 4)

How Much Vitamin A Do You Need?

The Reference Nutrient Intake (RNI) for vitamin A is 700 µg per day for adult men and 600 µg per day for adult women in the UK. 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.

What Is Vitamin A?

Vitamin 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. NOW Vitamin A provides 25,000 IU of retinol from fish liver oil, offering a highly bioavailable form that your body can use directly without needing conversion.

Types of Vitamin A: Retinol vs Beta-Carotene

This supplement contains retinol (preformed vitamin A) from fish liver oil. 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.

Potential Side Effects and Safety

Vitamin A toxicity is possible when high doses are taken for prolonged periods. Symptoms may include nausea, dizziness, headache, and liver damage. This product is not recommended for pregnant women or those planning pregnancy without medical advice. Do not exceed the recommended dose. If you are on medication or have a medical condition, consult your doctor before use.

Frequently Asked Questions

Can I take this vitamin A daily?

Due to the high potency, it is best to follow the dosage instructions on the label or as directed by a health care provider. Long-term daily use without medical supervision is not recommended.

What is the difference between IU and µg?

IU (International Units) is a measurement of biological activity. For vitamin A, 1 IU of retinol equals 0.3 µg RAE. Thus, 25,000 IU is approximately 7,500 µg RAE.

Is this product suitable for vegans?

No, because it is derived from fish liver oil. Vegans should consider plant-based beta-carotene supplements.
