Vitamin K2 is one of the most important and often overlooked nutrients for maintaining strong, healthy bones. While calcium and vitamin D tend to get the spotlight, vitamin K2 plays a critical directing role, ensuring minerals are used properly within the body.
Understanding the vitamin K2 benefits helps explain why it’s such a key part of Advanced Bone Complex.
What is Vitamin K2?
So, what is vitamin K2?
Vitamin K2 is a fat-soluble vitamin that belongs to the vitamin K family, but it has a very different role from vitamin K1. While vitamin K1 is primarily involved in blood clotting, vitamin K2 is responsible for activating proteins that guide calcium to bones and teeth.
This makes vitamin K2 particularly important for bone strength and skeletal integrity.
Vitamin K2 benefits for bones
One of the most important vitamin K2 benefits is its role in bone mineralisation.
Vitamin K2 activates osteocalcin, a protein that binds calcium into the bone matrix. Without enough vitamin K2, calcium may circulate in the body without being effectively incorporated into bone.
Key vitamin K2 benefits include:
- Supporting proper calcium placement in bones
- Helping maintain bone density and strength
- Supporting long-term skeletal health
- Working synergistically with vitamin D and magnesium
This is why vitamin K2 is such an important part of Advanced Bone Complex.
Why we chose K2vital for our bone supplements
We chose K2VITAL® as the source of vitamin K2 in Advanced Bone Complex because it offers exceptional purity, stability and proven bioavailability. This premium, all-trans form of menaquinone-7 (MK-7) is carefully manufactured to ensure it remains active and effective throughout the product’s shelf life.
Vitamin K2 plays a crucial role in directing calcium into the bones where it belongs, working in synergy with magnesium and vitamin D to support true bone mineralisation. By selecting K2VITAL®, we ensure reliable quality and optimal efficacy to support long-term skeletal health.
Is Vitamin K2 the same as Vitamin K?
A common question is: is vitamin K2 the same as vitamin K?
While both belong to the vitamin K family, they have different roles:
- Vitamin K1 → primarily supports blood clotting
- Vitamin K2 → supports calcium regulation and bone health
For bone support, vitamin K2 is the more relevant form.
Should you take Vitamin D with K2?
Many people ask, should you take vitamin D with K2?
Yes, these two nutrients work best together. Vitamin D helps increase calcium absorption from the diet, while vitamin K2 helps direct that calcium into bones, where it’s needed most. Without vitamin K2, increased calcium absorption may not translate into stronger bones.
This synergy is why Advanced Bone Complex includes both vitamin D3 and K2.
How much Vitamin K2 per day?
So, how much vitamin K2 per day do you need?
There is currently no official recommended daily intake in the UK, but many supplements provide amounts in the range of 75–120 micrograms (µg) per day, which is commonly used in bone health formulations.
Advanced Bone Complex provides vitamin K2 in a carefully balanced amount designed to work synergistically with vitamin D3 and magnesium.
What foods contain Vitamin K2?
If you’re wondering what foods contain vitamin K2, it’s mainly found in fermented and animal-based foods, such as:
- Natto (fermented soybeans)
- Certain cheeses
- Egg yolks
- Milk fat
- Liver
However, dietary intake is often low, which is why supplementation can be beneficial, particularly for bone health.
Who should not take Vitamin K2?
While vitamin K2 is safe for most people, who should not take vitamin K2?
Anyone taking vitamin K–antagonist blood-thinning medication (such as warfarin) should consult their healthcare professional before using vitamin K2 supplements.
Vitamin K2 in Advanced Bone Complex
Vitamin K2 has been included in Advanced Bone Complex to ensure minerals are used effectively - not just consumed. By supporting proper calcium placement and working alongside vitamin D3 and magnesium, vitamin K2 helps create the ideal conditions for strong, resilient bones over time.
