Superior Source Vitamin A 10,000 IU Food Supplement - Supports Normal Vision, Immune Function, Skin & Bone Health - Non-GMO & Gluten-Free - 100 MicroLingual Tablets

What Makes the MicroLingual Form Special?

The MicroLingual tablet is designed to dissolve rapidly on or under the tongue, delivering vitamin A directly into the bloodstream without needing to be swallowed. This sublingual administration is ideal for those who find pills difficult to take, including older adults and bariatric patients, and may improve absorption for individuals with digestive concerns. Each tablet disintegrates in seconds, providing a precise 10,000 IU dose without water or chewing.

Vitamin A Benefits

• Normal vision: Vitamin A contributes to the maintenance of normal vision, particularly in low light, as it forms part of the rhodopsin protein needed for night vision.
• Immune function: It contributes to the normal function of the immune system by supporting mucosal barriers and immune cell activity.
• Skin health: As an antioxidant, vitamin A helps maintain normal skin by promoting cell turnover and a clear complexion.
• Bone health: Vitamin A works alongside vitamin D and other nutrients to support normal bone development and remodelling.
• Reproductive health: Adequate vitamin A is important for normal reproductive function in both men and women.

What Is Vitamin A?

Vitamin A is a fat-soluble vitamin essential for many bodily processes. It occurs in two main forms: preformed vitamin A (retinol) from animal sources, and provitamin A carotenoids (such as beta-carotene) from plants. The body converts both into active forms. This supplement provides vitamin A as retinyl palmitate, a highly bioavailable and stable form of retinol.

Types of Vitamin A: Retinol vs. Beta-Carotene

Preformed vitamin A (retinol) from animal products is readily used by the body without conversion. In contrast, beta-carotene must be converted into retinol – a process that becomes less efficient with age, certain health conditions, and genetic variations. Retinol-based supplements, such as this one, offer a more predictable and immediate source of vitamin A activity. Superior Source use retinyl palmitate, ensuring consistent potency and absorption.

How Much Vitamin A Do You Need?

The UK Reference Nutrient Intake (RNI) for vitamin A is 700 µg (2,333 IU) per day for men and 600 µg (2,000 IU) for women. Each MicroLingual tablet provides 10,000 IU (3,000 µg retinol), which exceeds the RNI and is above the UK safe upper level for supplements of 1,500 µg retinol (5,000 IU). This high dose may be appropriate for individuals with increased needs due to dietary restrictions, malabsorption, or oxidative stress. However, it is essential not to exceed one tablet daily and to consult a health care professional before use, especially if pregnant, breastfeeding, or taking other supplements containing vitamin A.

Potential Side Effects and Safety

While vitamin A from food is generally safe, high doses from supplements can accumulate and cause toxicity. Symptoms of acute toxicity include nausea, dizziness, headaches, and blurred vision. Chronic excess may lead to liver damage, bone pain, and birth defects. Do not exceed the recommended dose. This supplement is non-GMO, gluten-free, and free from additives, preservatives, and dyes. Because the sublingual form absorbs efficiently, adhere strictly to the serving size of one tablet daily. Food supplements should not replace a varied diet and healthy lifestyle. Keep out of reach of young children.

Frequently Asked Questions

Is this supplement suitable for vegans?

No, because the vitamin A is derived from retinyl palmitate, which is typically animal-sourced. Vegans may prefer a beta-carotene-based supplement.

Can I take this with other supplements?

Vitamin A works well alongside vitamins D, E and K2 as they are fat-soluble and support similar systems. However, avoid taking multiple products containing high doses of preformed vitamin A to stay within safe limits.

How should I store these tablets?

Store the bottle in a cool, dry place away from direct sunlight. The tablets are moisture-sensitive, so keep the lid tightly closed after each use.
