Overview
Bronson's Vitamin K2+D3 Magnesium Glycinate Supplement combines three bone and heart-focused nutrients, vitamin K2, vitamin D3 and magnesium glycinate, into one 60-capsule bottle. It is built as a 3-in-1 formula rather than requiring separate bottles for each nutrient.
D3 supports calcium absorption, K2 helps direct that calcium toward bone rather than arteries, and magnesium glycinate is a more gently absorbed magnesium form than magnesium oxide, so the combination targets bone and cardiovascular support from a few angles in one capsule. It is labeled non-GMO, gluten free and soy free, though the listing does not state individual milligram or microgram amounts for each of the three ingredients.
- Vitamin K2, D3 and magnesium glycinate in one capsule
- 3-in-1 bone and heart health formula
- 60 capsules per bottle
- Non-GMO, gluten free, soy free
Who it's for
Fits people who want to consolidate D3, K2 and magnesium into a single capsule instead of three separate bottles, particularly anyone focused on bone or heart health support. Less useful for anyone who needs to dose each of the three nutrients independently or at specific, higher amounts than a combination formula provides.
Strengths and trade-offs
Drawn from this product's published specifications.
- Combines D3, K2 and magnesium glycinate in one capsule
- Magnesium glycinate is gentler on digestion than magnesium oxide
- Non-GMO, gluten free, soy free
- Individual nutrient amounts per capsule are not listed here
- No amazon reviews attached to check tolerance or results
- A combination formula limits dosing flexibility for any single nutrient
Performance notes
The formula leans on how these three nutrients work together, D3 raising absorbed calcium, K2 routing it into bone rather than soft tissue, and magnesium glycinate supporting the enzymatic processes both vitamins depend on, rather than any one ingredient acting alone. Magnesium glycinate in particular is chosen over cheaper magnesium salts because it tends to cause less digestive upset.
