Bronson Vitamin K2 + D3 Extra Strength – 120 Capsules
Bronson Vitamin K2 + D3 Extra Strength is a high-potency, 2-in-1 dietary supplement combining vitamin D3 (cholecalciferol) and vitamin K2 (MK-7 menaquinone) to support bone health and normal calcium utilization. The formula brings together two fat-soluble vitamins that perform complementary roles in maintaining normal bone function and calcium metabolism.
Each capsule provides 250 mcg vitamin D3 (10,000 IU), equivalent to 1,250% of the labeled Daily Value, alongside 120 mcg vitamin K2 (MK-7), equivalent to 100% of the labeled Daily Value. Vitamin D3 supports calcium absorption, healthy bones and normal immune function, while vitamin K2 contributes to normal blood clotting and the maintenance of healthy bones. The combination is marketed by Bronson for bone and heart support.
This Extra Strength formula comes in a 120-capsule bottle containing 120 servings. The packaging identifies the product as Non-GMO, gluten-free and soy-free and displays laboratory-testing and GMP manufacturing quality claims. Bronson Laboratories is listed as the manufacturer, with a company address in New York, USA; however, the actual manufacturing country is not stated on the supplied product label. Because each capsule contains a high dose of vitamin D3, use should be reviewed with a healthcare professional.

Key Ingredients
The formula contains two active vitamins. The following amounts refer to one capsule, as declared in the supplied Supplement Facts.
Vitamin D3 (Cholecalciferol) — 250 mcg (10,000 IU)
Provides 250 mcg vitamin D3, equivalent to 10,000 International Units and 1,250% of the labeled Daily Value. Cholecalciferol is a form of vitamin D that contributes to normal calcium and phosphorus absorption, maintenance of healthy bones and normal immune function. This is a high-potency dose intended for use with appropriate professional guidance.
Vitamin K2 (MK-7 Menaquinone) — 120 mcg
Provides 120 mcg vitamin K2 as MK-7 menaquinone, equivalent to 100% of the labeled Daily Value. Vitamin K contributes to normal blood clotting and bone maintenance. Vitamin K2 is involved in activating vitamin K-dependent proteins associated with calcium regulation, complementing vitamin D3’s role in calcium absorption.
Other ingredients: Modified cellulose capsule, microcrystalline cellulose, magnesium stearate and silicon dioxide. These are listed separately from the two active vitamins. Although a cellulose capsule is used, the supplied label does not explicitly confirm vegetarian or vegan certification for the complete product.

Formula Details
Understanding the Two Vitamin Strengths: Each capsule contains 250 mcg vitamin D3, equal to 10,000 IU, and a separate 120 mcg vitamin K2 as MK-7. The 250 mcg figure refers to vitamin D3, not vitamin K2. Both vitamins are declared individually in the Supplement Facts, with no proprietary blend or undisclosed active ingredient concentration.
Complementary Nutritional Roles: Vitamin D3 helps the body absorb calcium and supports normal bones and immune function. Vitamin K2 contributes to the normal function of vitamin K-dependent proteins involved in bone and calcium metabolism. Although the combination is marketed for bone and heart support, it should not be considered a treatment for cardiovascular or bone disease. The 10,000 IU vitamin D3 strength is substantially above typical daily maintenance intake and warrants professional guidance, particularly for ongoing use.
