Carlson A y D - 10000 UI Vitamina A, 400 UI Vitamina D3, 100 Perlas Blandas

What is Carlson A & D and why combine them?

Carlson A & D combines two essential fat-soluble vitamins in one convenient softgel. With 10,000 IU (3,000 mcg RAE) of vitamin A and 400 IU (10 mcg) of vitamin D3, this supplement is designed to support multiple bodily functions. Vitamins A and D work together: while vitamin D3 contributes to calcium metabolism, vitamin A is involved in vision and skin health. Each batch is tested by an FDA-registered laboratory to ensure potency and quality. An ideal supplement for those looking to maintain an adequate intake of these vitamins, especially during periods of reduced sun exposure.

Health Benefits of Vitamin A and D3

Vitamin A (retinol) contributes to the maintenance of normal vision, the normal function of the immune system, and skin health. It also plays a role in iron metabolism. Vitamin D3 (cholecalciferol) contributes to the normal absorption and utilization of calcium and phosphorus, the maintenance of normal blood calcium levels, bone health, muscle function, and the normal function of the immune system. Both vitamins are fat-soluble and are stored in the body, so a balanced intake is important for overall well-being.

How much vitamin A and D do you need? Recommended dosage

This product provides 10,000 IU (3,000 mcg RAE) of vitamin A and 400 IU (10 mcg) of vitamin D3 per softgel. The recommended dose is one softgel daily, preferably with a fat-containing meal to optimize absorption. The tolerable upper intake level (UL) established by EFSA for preformed vitamin A is 3,000 mcg RAE per day in adults, so this dose is at the upper limit. For vitamin D3, the UL is 100 mcg (4,000 IU) per day, so 400 IU is a moderate dose. Do not exceed the recommended dose. Consult a healthcare professional before use if you are pregnant, breastfeeding, or have liver or thyroid problems.

Differences between vitamin A and D: forms and sources

The vitamin A in this product is retinol (preformed vitamin A), the most bioavailable form found in animal-derived foods. Vitamin D3 is cholecalciferol, the form the body produces with sun exposure and found in animal sources such as fish oil. Although the exact source is not specified on the label, Carlson traditionally uses cod liver oil for its A&D products. The combination of both vitamins in a single softgel facilitates daily supplementation and ensures a balanced intake.

How to choose a quality vitamin A and D supplement

Carlson is a recognized brand in the dietary supplement sector, with decades of experience. Each batch undergoes potency and purity testing by FDA-registered laboratories, ensuring that the product contains what the label indicates. The softgels are easy to swallow, and their oil formulation promotes the absorption of fat-soluble vitamins. When choosing a supplement, look for brands that perform independent quality testing and provide clear dosage information. This product is non-GMO and gluten-free (according to manufacturer information).

Possible side effects and contraindications

In high doses, vitamin A can cause toxicity (hypervitaminosis A) with symptoms such as nausea, headache, and liver damage. Given that this dose is at the upper tolerable limit, it is not recommended to combine it with other supplements containing vitamin A. Vitamin D3 at doses of 400 IU is safe for most adults, but very high doses (more than 4,000 IU per day) can cause toxicity. Consult your doctor before starting supplementation, especially if you are pregnant, breastfeeding, or taking medications such as anticoagulants.
