Score 58
An extremely high-dose D3 (25,000 IU) supplement with a low K2 (MK-7) dose, primarily for specific, medically supervised D3 repletion, not for general daily use.
Analysis
This supplement delivers a massive 625 mcg (25,000 IU) of Vitamin D3 as Cholecalciferol, an extremely high dose typically reserved for significant deficiency correction under medical supervision, not for daily general use. It is paired with a comparatively low 45 mcg of Vitamin K2 as Menaquinone-7 (MK-7). The significant imbalance in these doses is a key characteristic of this product.
This formulation is specifically for individuals with severe Vitamin D deficiency or other conditions requiring a very high D3 intake, always under the guidance of a healthcare professional. It is not intended for the average user seeking general bone or cardiovascular support due to the overwhelming D3 dose and the relatively insufficient K2 pairing for that level of D3.
Pros
- Provides an exceptionally high dose of Vitamin D3 (25,000 IU) for specific repletion needs.
- Includes the well-regarded Menaquinone-7 (MK-7) form of Vitamin K2.
Cons
- The Vitamin D3 dose (25,000 IU) is far too high for routine daily supplementation for most individuals.
- The K2 dose (45 mcg) is very low, especially when paired with such a high D3 dose, creating a significant imbalance.
- Higher price per serving compared to most D3/K2 combination products.
- Unsuitable for general wellness without strict medical guidance.
Warnings
- The extremely high Vitamin D3 dose requires strict medical supervision and is not for daily self-medication due to potential for toxicity and hypercalcemia. Consult a healthcare professional before use.
- Vitamin K may interact with blood-thinning medications; professional advice is crucial if on such medications.
- Do not exceed recommended dosages without explicit medical instruction.

Goals
Impact
Moderate effect
While D3 is essential for calcium absorption, such an extreme dose without a proportionally high K2 dose raises concerns about calcium distribution, potentially compromising optimal bone health rather than supporting it. Medical guidance is paramount.
Impact
Moderate effect
While D3 and K2 contribute to heart health, the extreme D3 dose with a relatively low K2 creates a significant imbalance, potentially leading to concerns rather than benefits without careful management. It is not suitable for general heart health support.
Impact
Moderate effect
The extreme D3 dose with low K2 poses risks for calcium management, which could negatively impact skeletal health if not carefully managed. It's not a suitable product for general joint support.
Impact
Moderate effect
The overwhelming D3 dose combined with a low K2 dose is imbalanced for cardiovascular support, as K2 is crucial for directing calcium. This product needs medical oversight to prevent adverse effects related to calcium metabolism.
Impact
Lower effect
Given the extreme D3 dose and K2 imbalance, this product is not suitable for a general anti-aging strategy without professional medical guidance. It presents a risk for calcium dysregulation if not properly managed.
Impact
Lower effect
This product's extremely high D3 dose makes it unsuitable for general health maintenance for most people. It's a targeted, high-potency intervention that requires professional supervision, not a general wellness supplement.
Ingredients
| Ingredient | Amount per serving |
|---|---|
Vitamin D3 | 625 mcg |
Vitamin K2 | 45 mcg |
Vitamin K 55
As a Vitamin K product, the 45 mcg MK-7 dose is quite low, especially when paired with an extremely high D3 dose. This imbalance limits its effectiveness and appropriateness as a balanced K vitamin option within the collection.
