Types of Vitamin A: Retinyl Palmitate vs. Beta-Carotene
Vitamin A is available in two primary forms: preformed vitamin A (retinoids) and provitamin A carotenoids like beta-carotene. NaturesPlus Vitamin A uses retinyl palmitate, a preformed retinoid that your body can absorb and use directly without conversion. This makes it especially beneficial for individuals who may have difficulty converting beta-carotene into active vitamin A. Because it is preformed, it's important to follow recommended dosages to avoid potential toxicity.
The Benefits of Vitamin A for Vision, Immunity, and Skin
Vitamin A contributes to several key aspects of your health. Here are the main benefits supported by research:
-
Eye Health: Vitamin A is a critical component of rhodopsin, a protein in the retina that enables vision in low light. It also helps maintain the health of the cornea and may reduce the risk of age-related vision decline.
-
Immune Support: Vitamin A promotes the production and function of white blood cells, which help defend your body against infections. It also supports the integrity of mucosal barriers, your first line of defense.
-
Skin Health: This vitamin encourages healthy skin cell turnover and can help maintain a smooth, clear complexion. It is frequently used in skincare for its rejuvenating properties.
-
Bone Growth: Vitamin A is necessary for proper bone development and remodelling, contributing to overall skeletal strength.
How Much Vitamin A Should You Take?
The Recommended Dietary Allowance (RDA) for vitamin A varies by age and gender. For adult men, the RDA is 900 mcg RAE (3,000 IU), and for women, it is 700 mcg RAE (2,333 IU). NaturesPlus Vitamin A provides 10,000 IU (3,000 mcg RAE) per serving, which is above the RDA but within the Tolerable Upper Intake Level (UL) of 10,000 IU for adults. Always consult your healthcare provider before starting any supplement, especially if you are pregnant, nursing, or taking medication.
What Is Vitamin A and Why Is It Important?
Vitamin A is a fat-soluble nutrient that plays a vital role in maintaining overall health. It is essential for vision, immune function, and skin cell production. Your body cannot synthesise this essential vitamin, so it must be obtained through diet or supplementation. NaturesPlus Vitamin A 10,000 IU provides a potent dose of vitamin A as retinyl palmitate, a highly bioavailable form that your body can use efficiently. Each water-dispersible tablet ensures optimal absorption, making it a convenient choice for daily supplementation.

Potential Side Effects and Safety Considerations
Vitamin A is generally safe when taken within recommended limits. However, excessive intake of preformed vitamin A can lead to toxicity, with symptoms such as nausea, dizziness, and liver damage. The Tolerable Upper Intake Level (UL) for adults is 10,000 IU. Do not exceed the recommended dose. If you have liver disease, are pregnant, or are taking medications like retinoids, consult your doctor before use. This product has been licensed under the Natural Health Products Regulations.
