Carlson - Vitamin A & D3, 10,000 IU (3,000 mcg RAE) Vitamin A, 400 IU (10 mcg) Vitamin D3, 300 Soft Gels

What is Carlson A & D and why is it a key combination?

Carlson A & D combines two essential fat-soluble vitamins in one convenient softgel. Each dose provides 10,000 IU (3,000 mcg RAE) of vitamin A and 400 IU (10 mcg) of vitamin D3 (cholecalciferol). This formula is designed for those seeking comprehensive nutritional support for vision, skin, bones, and the immune system. Carlson Laboratories tests every batch for potency and quality in an FDA-registered laboratory, ensuring product reliability.

Benefits of vitamins A and D3 for your health

Vitamin A contributes to the maintenance of normal vision, the normal function of the immune system, and skin health. For its part, vitamin D contributes to the normal absorption and utilization of calcium and phosphorus, the maintenance of bones under normal conditions, and the normal function of the immune system. Both vitamins work together to support calcium metabolism, a key process for bone health. The combination of vitamin A and D3 in a single supplement facilitates daily intake and ensures beneficial synergy.

How much vitamin A and D3 to take per day? Recommended dosage

The recommended daily dose of this product is one softgel, which provides 10,000 IU (3,000 mcg RAE) of vitamin A and 400 IU (10 mcg) of vitamin D3. The amount of vitamin A is equivalent to the tolerable upper intake level (UL) established by the EFSA for adults, so this dose should not be exceeded without medical supervision. Vitamin D3 is within the safe range for adults. Always consult a healthcare professional before starting any supplementation, especially if you are pregnant, breastfeeding, or taking other medications.

Differences between vitamin D2 and D3

Vitamin D3 (cholecalciferol) is the most bioavailable form and the one the body naturally produces with sun exposure. Carlson uses animal-derived vitamin D3 (lanolin), which is the most studied and recommended. In contrast, vitamin D2 (ergocalciferol) comes from plant sources and is less effective at raising and maintaining blood vitamin D levels. Therefore, D3 is the preferred form in high-quality supplements.

How to choose the best vitamin A and D supplement

When selecting a supplement, it is important to look at the vitamin form (D3 versus D2), the dosage, and the manufacturer's reputation. Carlson A & D offers vitamin A in the form of retinol (active and preformed) and vitamin D3 as cholecalciferol. The softgels facilitate absorption and are easy to swallow. In addition, the product has been tested by an FDA-registered laboratory, which ensures its potency and purity. For those looking for a reliable supplement, this formula is a solid option.

Possible side effects and contraindications

Vitamins A and D are fat-soluble and are stored in the body. Excessive doses of vitamin A can lead to toxicity, so it is essential not to exceed the recommended daily dose. High doses of vitamin D can also cause adverse effects. This product is contraindicated in people with hypervitaminosis A or D, severe kidney or liver diseases. Consult your doctor before use if you have any medical condition or are taking other supplements. This product is a food supplement and should not be used as a substitute for a balanced diet.
