Major Vitamin A Capsules, 100 Softgels

Benefits of Vitamin A

• Vision Health: Vitamin A contributes to the maintenance of normal vision, particularly in low light, as it is a component of rhodopsin.
• Immune Support: It helps maintain the normal function of the immune system and the integrity of mucous membranes.
• Skin Health: Retinoids derived from vitamin A support normal cell turnover and maintenance of healthy skin.
• Reproductive Health: It plays a role in normal reproductive function in both men and women.
• Antioxidant Activity: Although this product contains retinol (not beta-carotene), vitamin A contributes to normal antioxidant processes.

What is Vitamin A?

Vitamin A is a fat-soluble nutrient essential for maintaining normal vision, immune function, and skin integrity. It exists in two primary forms: preformed vitamin A (retinol) found in animal products, and provitamin A (beta-carotene) from plant sources. Major Vitamin A Capsules provide 10,000 IU of vitamin A as retinyl palmitate, a highly bio-available esterified form. This nutrient is involved in cellular communication, growth, and antioxidant defence. Because the body stores excess vitamin A in the liver, consistent intake from supplements and diet helps maintain optimal levels.

How Much Vitamin A Do You Need?

In the UK, the Reference Nutrient Intake (RNI) for vitamin A is 700 µg per day for men and 600 µg per day for women. Needs increase during pregnancy and lactation. Each Major soft gel capsule delivers 10,000 IU (3,000 µg RAE), which exceeds the RNI. This higher dose may be appropriate for short-term uses under medical guidance. The UK safe upper limit for preformed vitamin A from supplements is 1,500 µg (5,000 IU) per day. Long-term intake above this level can increase the risk of toxicity, so it is important to consider total vitamin A from diet and other supplements.

Types of Vitamin A: Retinol vs. Beta-Carotene

Vitamin A occurs in two main dietary forms. Preformed vitamin A (retinol, retinal, retinoic acid) is found in animal sources such as liver, eggs, and dairy, and is readily used by the body. Provitamin A carotenoids like beta-carotene are found in colourful fruits and vegetables and must be converted to retinol in the body, with conversion rates varying by individual. Major Vitamin A Capsules utilise retinyl palmitate, the esterified form of retinol, which is stable and efficiently absorbed. For those preferring plant-based options, a separate beta-carotene supplement may be considered, but this product is not suitable for vegans.

Safety and Side Effects

Vitamin A is essential, but excessive intake can lead to hypervitaminosis A, with symptoms including nausea, dizziness, blurred vision, and liver damage. Chronic toxicity may occur with daily doses exceeding 1,500 µg (5,000 IU) from supplements over extended periods. Acute toxicity is rare but possible with very high single doses. Pregnant women are advised to avoid high-dose vitamin A supplements because they can cause birth defects. Always consult your health care professional before starting a new supplement, especially if you are pregnant, nursing, or have liver disease. Store in a cool, dry place and keep out of reach of children.

Frequently Asked Questions

Can I take vitamin A with other supplements?

Yes, but be mindful of total intake. Many multivitamins and fish liver oils contain vitamin A. Check labels to avoid exceeding the safe upper limit.

What is the difference between IU and mcg RAE?

IU (International Units) measure biological activity. For retinol, 1 IU equals 0.3 µg RAE, so 10,000 IU equals 3,000 µg RAE.

How long does one bottle last?

With 100 softgels, taking one daily provides a supply of approximately three months.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. Always read the label and follow directions for uses.
