Rx D3 Forte by Rx Vitamins for Pets – High-Potency Vitamin D3 Support with Cholecalciferol

Rx D3 Forte by Rx Vitamins for Pets is a palatable liquid source of pure cholecalciferol formulated for canine and feline patients. This high-potency pet vitamin D3 supplement provides cholecalciferol, the precursor to Vitamin D3 for all animals, blended with MCT oil at a higher concentration than standard Rx D3.

Key Rx D3 Forte Benefits

  • Provides high-potency Vitamin D3 as pure cholecalciferol.
  • Supports patients with vitamin D insufficiency under veterinary guidance.
  • Supplies 15,000 IU Vitamin D3 per 1 ml serving.
  • Provides 500 IU Vitamin D3 per drop, offering 5 times the potency per drop compared with standard Rx D3.
  • Includes a glass graduated dropper to support accurate serving size.

How Rx D3 Forte Works

Rx D3 Forte delivers cholecalciferol, the precursor to Vitamin D3, in an MCT oil base at a higher concentration to better suit the needs of the severely vitamin D3 deficient patient, the larger patient, or any other patient that would benefit from a higher concentration. A vitamin D3 test using the VDI Laboratory test kit is recommended to establish a safe and effective dosage, with retesting in 8–10 weeks recommended to ensure vitamin D3 sufficiency.

Key Functional Ingredients Include:

  • Vitamin D3: Provided as cholecalciferol to support vitamin D3 intake in dogs and cats.
  • Cholecalciferol: The precursor to Vitamin D3 for all animals.
  • MCT Oil: Used as the liquid carrier for palatable administration.

This formula is intended for canine and feline patients only and should be used with appropriate vitamin D3 testing and veterinary guidance.

Rx D3 Forte Is Formulated For

  • Dogs and cats needing vitamin D3 support.
  • Canine and feline patients with vitamin D insufficiency.
  • Larger patients or those needing a higher-concentration cholecalciferol supplement.
  • Veterinary-guided wellness plans that include vitamin D3 testing and retesting.
