Superior Source Vitamina A 10.000 UI – Suplemento Alimenticio para la Visión, Inmunidad, Piel y Huesos – 100 Comprimidos MicroLinguales

What is Vitamin A and why is it essential?

Vitamin A is a fat-soluble nutrient essential for multiple functions in the body. It comes in two main forms: preformed vitamin A (retinol, found in animal-based foods) and provitamin A carotenoids (such as beta-carotene, from plant sources). This Superior Source supplement provides vitamin A in its retinol form, the most bioavailable and directly usable by the body. Each MicroLingual tablet provides 10,000 IU (equivalent to 3,000 mcg of retinol equivalents), a dose that largely covers the recommended daily needs for adults.

Vitamin A contributes to the maintenance of normal vision, the normal functioning of the immune system, the maintenance of normal skin, and the maintenance of normal bones. These claims are authorized by the European Food Safety Authority (EFSA).

Benefits of Vitamin A for your health

Thanks to its role in cell differentiation and immune function, vitamin A is a pillar for overall health. Among its EFSA-backed benefits are:

• Normal vision: Vitamin A is an essential component of rhodopsin, a protein in the retina necessary for adaptation to light and dark. Its intake contributes to the maintenance of healthy vision.
• Immune system: Helps maintain the body's defenses, participating in the production and activity of immune cells.
• Skin and mucous membranes: Promotes cell renewal and the integrity of the skin and mucous membranes, protecting against external aggressions.
• Bones: Involved in bone metabolism, contributing to mineralization and the maintenance of bone structure.

It is important to note that these effects occur in the context of a balanced diet and a healthy lifestyle. Food supplements should not be used as a substitute for a varied diet.

How to safely take Vitamin A?

The recommended dose for adults is one tablet daily, preferably with a meal containing fat to optimize its absorption. Since each tablet provides 10,000 IU (3,000 mcg RAE), which is the maximum tolerable limit established by health authorities, it is crucial not to exceed this dose. Its use is not recommended for pregnant or breastfeeding women without prior consultation with a healthcare professional, as an excess of vitamin A can be harmful to the fetus.

People with liver diseases, kidney failure, or those taking medications such as oral retinoids should consult their doctor before starting supplementation. Likewise, high alcohol consumption can increase the risk of vitamin A-induced liver toxicity.

What makes this Vitamin A supplement special?

Superior Source has developed a unique formula with MicroLingual technology: the tablets dissolve instantly on or under the tongue, facilitating absorption without the need to swallow pills. This feature makes them ideal for older adults, bariatric patients, or those who have difficulty swallowing. In addition, the product is non-GMO, gluten-free, and contains no artificial additives, preservatives, or colorings, which ensures a clean and effective option.

Manufactured in the United States in a family-owned facility since 1998, Superior Source maintains a commitment to quality and purity. Each batch is laboratory tested to verify its potency and safety.

Possible side effects and precautions

Although vitamin A is safe at recommended doses, excessive consumption can lead to hypervitaminosis A, with symptoms such as dry skin, headache, fatigue, nausea, and blurred vision. In severe cases, it can affect the liver and bones. Therefore, it is essential to respect the indicated daily dose and not combine it with other supplements containing vitamin A without medical supervision.

Food supplements should not be used as a substitute for a balanced diet. Do not exceed the recommended daily dose. Keep out of reach of small children.

How to choose the best Vitamin A supplement

When selecting a vitamin A supplement, consider the form (retinol vs. beta-carotene), the dose in IU or mcg RAE, and quality certifications. This Superior Source product offers pure retinol in a highly bioavailable presentation, with guarantees of purity and responsible manufacturing. Its MicroLingual format is an additional advantage for those seeking convenience and rapid absorption.

Remember that supplementation should complement a diet rich in vitamin A sources, such as liver, carrots, sweet potatoes, spinach, and dairy products. If you have questions about your specific needs, consult a healthcare professional.
