Overview
Bronson's combination capsule pairs 10,000 IU of vitamin D3 with 120 mcg of vitamin K2 as MK-7 in a non-GMO, easy to swallow formula, 120 capsules per bottle, aimed at bone and heart health support.
10,000 IU of D3 is well above the standard 600-800 IU daily guideline, making this better suited to someone with a diagnosed deficiency or a doctor's recommendation than to general maintenance. MK-7 is the longer-acting form of K2, commonly paired with D3 because D3 aids calcium absorption while K2 helps direct that calcium toward bone rather than soft tissue.
- 10,000 IU vitamin D3 per serving
- 120 mcg vitamin K2 as MK-7
- Non-GMO formula
- 120 capsules per bottle
Who it's for
For adults with a known vitamin D deficiency or a doctor's instruction to combine high-dose D3 with K2 for bone and cardiovascular support. Not for someone simply looking for a baseline daily vitamin dose.
Strengths and trade-offs
Drawn from this product's published specifications.
- High-dose D3 paired with MK-7 form of K2
- Easy to swallow capsules
- High dose exceeds typical daily maintenance needs
Performance notes
Vitamin D3 supports calcium absorption in the gut, while K2 MK-7 activates proteins that help route that calcium toward bone rather than arteries, a common rationale for pairing the two. At 10,000 IU, the dose sits well above general guidance, so real-world benefit depends heavily on a person's starting vitamin D level.
