Progressive Vitamin D3 Extra Strength delivers 2500 IU of vitamin D3 to support immune function and calcium absorption. Each tablet provides the cholecalciferol form your body recognizes and uses most effectively. The extra strength formula works for adults who need meaningful vitamin D support beyond basic maintenance levels.
Why It Works
PROVEN POTENCY: 2500 IU provides substantial vitamin D3 levels in one daily tablet, unlike lower-dose formulas that require multiple pills.
SUPERIOR ABSORPTION: Uses vitamin D3 (cholecalciferol) rather than D2, which research shows is more effective at raising blood vitamin D levels.
CALCIUM PARTNERSHIP: Enhances your body's ability to absorb calcium and phosphorus from food for stronger bones and teeth.
What's Inside
Clean tablet formula with gluten-free ingredients and easy-swallow design. Contains 62.5 mcg (2500 IU) vitamin D3 per tablet with simple non-medicinal ingredients including cellulose and dicalcium phosphate.
Why we carry it: Progressive combines reliable third-party testing with honest pricing that makes daily vitamin D support accessible for Canadian families.
