Analysis updated August 2026 · How Scout scores
At a glance
Summary
This supplement contains beneficial ingredients such as Cholecalciferol (Vitamin D3) and Vitamin K2 as MK-7, which are important for bone and cardiovascular health. However, the presence of maltodextrin as a filler and the use of multiple additives like hypromellose and silicon dioxide slightly detract from its overall formulation quality. While it lacks harmful substances, the inclusion of these additives impacts its processing level, resulting in a moderate score.
Key ingredients 7
CholecalciferolVery Good
Cholecalciferol, or Vitamin D3, is a high-quality active ingredient that supports bone health and immune function. It is the preferred form of Vitamin D due to its superior absorption and efficacy compared to Vitamin D2. Adequate Vitamin D levels are crucial for calcium absorption and overall health.
Risks
Excessive intake can lead to hypercalcemia, a condition characterized by elevated calcium levels in the blood.
Benefits
Supports bone health, immune function, and enhances calcium absorption.
Vitamin K2 as MK-7Very Good
Vitamin K2 as MK-7 is a highly bioavailable form of Vitamin K that supports cardiovascular and bone health. It helps direct calcium to the bones and away from the arteries, reducing the risk of arterial calcification. MK-7 has a longer half-life, making it more effective in maintaining consistent Vitamin K levels.
Benefits
Supports cardiovascular health and enhances bone mineralization.
Vitamin K1Good
Vitamin K1 is essential for blood clotting and bone health. It is primarily found in leafy greens and is important for the synthesis of proteins involved in blood coagulation. While less potent than Vitamin K2 in bone health, it still plays a crucial role in maintaining overall health.
Benefits
Essential for blood clotting and contributes to bone health.
HypromelloseNeutral
Hypromellose is a cellulose-based compound used as a vegetarian capsule material. It is generally considered safe and inert, with no significant health impacts. It serves as an alternative to gelatin capsules for those avoiding animal products.
Benefits
Provides a vegetarian-friendly option for capsule formation.
Dicalcium PhosphateNeutral
Dicalcium phosphate is used as a dietary supplement and a tableting agent. It provides calcium and phosphorus, which are essential for bone health. However, its contribution in supplements is often minimal compared to dedicated calcium supplements.
Risks
Excessive intake may lead to imbalances in calcium and phosphorus levels.
Benefits
Contributes to bone health by providing calcium and phosphorus.
Silicon DioxideNeutral
Silicon dioxide is used as an anti-caking agent to prevent clumping in powdered ingredients. It is generally recognized as safe and does not contribute any nutritional value. Its inert nature makes it a common additive in supplements.
Benefits
Helps maintain the free-flowing nature of powdered ingredients.
MaltodextrinBad
Maltodextrin is a highly processed carbohydrate used as a filler or thickener. It has a high glycemic index, which can cause spikes in blood sugar levels. Additionally, it offers no nutritional benefits and is often derived from genetically modified corn.
Risks
High glycemic index may lead to blood sugar spikes and potential weight gain if consumed in excess.
