📋 Clinical Overview

A fixed-dose combination of essential water-soluble and fat-soluble vitamins, along with D-Panthenol (a provitamin of B5), formulated as a nutritional supplement. It is designed to correct and prevent deficiencies, support metabolic functions, enhance skin and mucosal health, and boost immunity. The combination is particularly relevant in the Indian context due to widespread micronutrient deficiencies, vegetarian diets, and limited sun exposure affecting Vitamin D synthesis.

💊 Dosage & Administration

Adult: As per the specific brand's prescribing information. Typically: 1 ml of oral drops/syrup once daily, or as directed by the physician. Often administered after a meal for better absorption of fat-soluble vitamins.

Note: For oral use only. Shake the bottle well before use. Use the measuring dropper/cup provided. Preferably take with or after a meal containing some fat to enhance absorption of Vitamins A and D3. Do not mix with hot beverages (can degrade Vitamin C).

⚠️ Contraindications

  • Known hypersensitivity to any component of the formulation.
  • Hypervitaminosis A or D.
  • Significant hypercalcemia.
  • Women who are or may become pregnant should avoid high-dose Vitamin A (>10,000 IU/day); this formulation's dose is low but caution advised.

🔬 Mechanism of Action

The combination acts synergistically to support fundamental biochemical pathways. Vitamin A is critical for vision (rhodopsin synthesis), cellular differentiation, and immune function. Vitamin D3 regulates calcium-phosphate homeostasis and modulates immune responses. Thiamine is a coenzyme (TPP) in carbohydrate metabolism and nerve conduction. Vitamin C is a potent antioxidant, cofactor for collagen synthesis, and enhances iron absorption. D-Panthenol, a precursor to pantothenic acid (Coenzyme A), is vital for fatty acid metabolism, epithelialization, and wound healing.

🤕 Side Effects

  • Generally well-tolerated at these doses. Rarely: Mild gastrointestinal discomfort, nausea.
  • Bright yellow discoloration of urine (due to riboflavin often present in B-complex, or Vitamin B2 metabolites).

🤰 Special Populations

Pregnancy: Category A/C (component-dependent). Vitamin A at this dose (1100 IU ~ 330 mcg RAE) is below the recommended daily allowance (770 mcg RAE) for pregnancy and is considered safe. However, excessive Vitamin A (>10,000 IU/day) is teratogenic. This formulation is likely safe, but use only under medical supervision. Vitamin D, B1, C, and D-Panthenol are safe and recommended.

Driving: No effect on driving ability.
