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.
<p>While the forms of D3 (Cholecalciferol) and K2 (Menaquinone-7) are good, the extreme imbalance in their doses, with a very high D3 and low K2, means the nutrient profile is not well-suited for general or balanced support. The D3 is too high for general use.</p>
<p>The product clearly lists the specific forms and quantities of Vitamin D3 and K2 (MK-7), providing straightforward and helpful information for consumers to understand its potent composition.</p>
<p>The value for money is very low for general users due to the extremely high D3 dose, which is not intended for regular use, and the comparatively low K2 dose. It only holds value for very specific, professionally guided scenarios.</p>
<p>With over 1200 reviews, the product has a solid base of customer feedback, which likely comes from users with specific needs or professional guidance for such a high D3 dose. This suggests targeted satisfaction.</p>
<p>Metabolic Maintenance is a brand often associated with professional-grade supplements, which can imply a focus on specific, high-potency formulations. Their presence often caters to a professional recommendation context.</p>
| Ingredient | Amount per serving |
|---|---|
Vitamin D3 | 625 mcg |
Vitamin K2 | 45 mcg |
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.
