A & D
Brand: Wonder Laboratories
Dr. Feb's Analysis
Scientific Mechanism
This supplement delivers high-potency support via Vitamin A (Retinyl Palmitate) and Vitamin D (Cholecalciferol). Vitamin A is essential for vision and immune cell differentiation; it binds to nuclear receptors to regulate gene expression. Vitamin D is a secosteroid hormone that enhances intestinal absorption of calcium and phosphate. Together, they facilitate cellular signaling pathways crucial for maintaining the structural integrity of bones and the functional integrity of the immune system.
Key Benefits
Key benefits include:
- Supports robust immune system function
- Promotes healthy vision and skin
- Aids in calcium absorption for strong bones
- Contributes to normal cell growth and differentiation
Usage & Safety
The standard dosage is 1 softgel daily, or as directed by a physician. Because this product contains 25,000 IU of Vitamin A—exceeding the recommended daily limit—strict adherence to dosage is critical. Do not use if pregnant, nursing, or of childbearing age due to teratogenic risks. Take with a meal containing fat to maximize absorption of these fat-soluble vitamins. Consult a doctor if taking other medications, particularly calcium supplements or thiazide diuretics.
