Quick answer
Choose Thorne's Advanced Bone Support if you want a broad, multi-mineral formula built around calcium and magnesium for everyday bone maintenance. Choose Vitamin K2 if your priority is targeted support for bone protein function, especially after menopause or when you already get calcium from food. They can be paired, but they are not interchangeable.

What each product actually supplies
Advanced Bone Support is a comprehensive bone support supplement that combines dicalcium malate and dimagnesium malate, two mineral forms each bound to malic acid. That means it delivers both calcium and magnesium in one formula rather than a single nutrient.
Vitamin K2 is a single-nutrient product. The catalog notes it offers more benefit for supporting bone health than vitamin K1, and that it provides nutritional rather than therapeutic support because it has no estrogenic effects.
Why the mineral forms matter
The malate forms in Advanced Bone Support are chelated minerals, meaning each calcium or magnesium molecule is bound to malic acid. This is a deliberate formulation choice, and it is the detail that separates it from a plain calcium carbonate tablet.
Vitamin K2 takes a different route. Instead of supplying the minerals your bones are built from, it supports the proteins that help direct calcium where it is needed. That is why it is often discussed alongside calcium rather than as a replacement for it.
Who tends to need which
The Advanced Bone Support catalog states that as many as half of all women in the United States older than 65 should be concerned about maintaining good bone health, and that certain groups are at particular risk. If you are not confident you get enough calcium and magnesium from food, a combined mineral formula is the more practical starting point.
Vitamin K2 is positioned for postmenopausal bone support but, because it has no estrogenic effects, the catalog also lists anorexics, dialysis patients, individuals with Parkinson's disease, and those with cirrhosis of the liver among the populations it can support nutritionally. If your diet already covers calcium and magnesium, K2 is the more focused addition.
Can you take both?
Yes, in principle, because they do different jobs: one supplies bone minerals, the other supports the proteins that use calcium. The trade-off is cost and pill count rather than a conflict. If you are already taking a calcium-rich diet plus a multivitamin, stacking both may be redundant, so review your total intake before adding a second bone product.
Trade-offs at a glance
- Breadth vs. focus: Advanced Bone Support delivers calcium and magnesium together, while Vitamin K2 delivers one nutrient aimed at bone protein function. Pick breadth if your mineral intake is uncertain; pick focus if it is already covered.
- Population fit: Vitamin K2 is positioned for postmenopausal bone support and, because it has no estrogenic effects, the catalog also lists anorexics, dialysis patients, individuals with Parkinson's disease, and those with cirrhosis of the liver. If you fall into one of those groups, K2 is the more specifically relevant option.
- Stacking and cost: Taking both is not a conflict, but it adds cost and pills, and may duplicate minerals you already get from food or a multivitamin. Audit your total calcium and magnesium intake before adding a second bone product.
Product facts
- Advanced Bone Support: Advanced Bone Support is a comprehensive bone support supplement containing dicalcium malate and dimagnesium malate, two calcium or magnesium molecules each bound to one molecule of malic acid. It covers two bone-relevant minerals in one product, so it suits people who are unsure whether their diet supplies enough calcium and magnesium.
- Vitamin K2: Vitamin K2 offers significant benefit for supporting bone health, more than vitamin K1, and provides nutritional rather than therapeutic support because it has no estrogenic effects. It is the more targeted choice when calcium intake is already handled and the goal is supporting how the body uses that calcium.
- Collagen Fit: Collagen Fit is an unflavored collagen powder with collagen peptides for joint health and lean muscle mass, plus nicotinamide riboside (NR) for cellular energy and repair. If your concern is joint comfort and muscle rather than bone mineral density, this is a different category of support worth considering instead of a bone mineral formula.
Which should you choose?
Choose this if
- You want a single formula supplying both calcium and magnesium for general bone support
- You are over 65 or otherwise concerned about maintaining bone health and are unsure your diet covers these minerals
- You prefer chelated mineral forms such as dicalcium malate and dimagnesium malate
Skip this if
- You already take a calcium and magnesium supplement and want only targeted bone protein support, in which case Vitamin K2 fits better
- Your main concern is joint comfort or lean muscle rather than bone mineral density, where Collagen Fit is the more relevant category
