Vitamin D3 helps you absorb calcium out of the gut. That is step one. Step two is making sure the calcium goes where it belongs — into bone tissue — and that is where vitamin K2 comes in. A calcium supplement without both is doing half a job.*
Keystone is built around that pairing rather than around a large calcium number on the front of the bottle. MK-7 is the long-acting form of K2, which is why it is the one specified here.*
Calcium is the primary mineral in bone tissue, and D3 supports its absorption.*
Vitamin K2 supports normal calcium utilisation as part of a healthy cardiovascular routine.*
BioPerine black pepper fruit extract is included to support absorption of the nutrients alongside it.*
Each part of this formula depends on the one before it. Here is the order it runs in.*
The mineral itself, and the primary structural component of bone tissue.*
Supports the absorption of calcium from the digestive tract.*
The long-acting form of K2, included to support normal calcium utilisation.*
A standardised extract included to support nutrient absorption across the formula.*
One capsule, twenty to thirty minutes before a meal.
The second capsule later in the day, same approach.
Bone support is measured in years, not weeks. Daily is the whole strategy.
Do not exceed the recommended dose. If you are pregnant, nursing, under 18, taking medication, or managing a known condition, talk to a healthcare professional before starting. Keep out of reach of children and store in a cool, dry place.
