Vitamin D3 is widely taken for bone and immune support, and it works best alongside vitamin K2, which helps direct the calcium D3 absorbs toward bone rather than soft tissue.* Bronson's Extra Strength formula pairs 10,000 IU of D3 with 120 mcg of K2 as MK-7, the longer-lasting form, in a tablet. The 360-count bottle is nearly a year's supply.

What's inside

• 10,000 IU vitamin D3 per tablet
• 120 mcg vitamin K2 as MK-7 per tablet
• 360 tablets – a 12-month supply at one per day
• Laboratory tested; GMO-free, gluten-free and soy-free
• Made in Bronson's own cGMP-registered facility in New York

How to use

Take one tablet daily with a meal containing fat. This is a high-dose D3 product intended for people who have been advised to take more than a maintenance amount; if you are unsure of your vitamin D status, a simple blood test can guide you. Vitamin K2 can interact with blood-thinning medications such as warfarin, so consult your healthcare provider before use if you take one.

Why we carry it

Bronson has manufactured in its own facility since 1960, and the brand's lab testing and clean free-from profile are consistent across its range. For customers who need a higher D3 dose with K2 included, this bottle delivers both at one of the lowest costs per day available.*
