Metabolic Nutrition | D3 + K2 | 90 Capsules

Metabolic Nutrition Vitamin D3 + K2 is a straightforward two-ingredient formula built around one of the most important nutritional pairings in modern supplementation: high-potency vitamin D3 for maintaining healthy vitamin D status, and vitamin K2 as menaquinone-7 to help direct calcium where it belongs. This is not a trendy kitchen-sink wellness product. It is a targeted foundational formula designed for people who want meaningful support for bone health, immune function, and calcium metabolism in a fully disclosed capsule.

Vitamin D3 is provided at 175 mcg, equivalent to 7,000 IU, as cholecalciferol. Cholecalciferol is the preferred supplemental form because it is the same form your body produces in response to sunlight exposure and is generally more effective than vitamin D2 at raising and maintaining circulating 25-hydroxyvitamin D levels. Mechanistically, vitamin D acts more like a hormone than a simple vitamin. It binds to the vitamin D receptor in multiple tissues, influencing calcium and phosphorus absorption, immune signaling, musculoskeletal function, and gene expression. At 7,000 IU, this is a robust daily dose relative to the general maintenance ranges commonly seen in multivitamins and basic wellness products. For users with low sun exposure, larger body size, darker skin tone, seasonal deficiency risk, or documented low vitamin D status, this level is often more relevant than the token 1,000-2,000 IU doses used for label decoration. What you notice is not a stimulant-like feeling on day one, but over time better support for structural health, recovery, and the baseline systems that make training and general wellness more resilient.

Vitamin K2 is dosed at 200 mcg as menaquinone-7, the longer-acting and generally preferred supplemental K2 form for daily use. K2 supports the activation of vitamin K-dependent proteins such as osteocalcin and matrix Gla protein. In plain terms, that means it helps your body utilize calcium intelligently: supporting incorporation into bone while helping reduce inappropriate calcium deposition in soft tissues. This is why pairing K2 with higher-dose D3 is not optional window dressing when a formula is designed well. D3 increases calcium absorption; K2 helps regulate where that calcium goes. At 200 mcg, the K2 dose is strong and consistent with meaningful daily support.

The synergy here is the entire point. D3 raises the calcium-management demand; K2 helps manage that demand. Together they create a more complete formula than D3 alone, especially for people using a higher-potency D3 product consistently. The label is fully transparent with no proprietary blend, which matters in a category crowded with vague wellness products that do not tell you enough to evaluate the formula.

What to expect: day one is subtle, because these are foundational nutrients, not acute-feel ingredients. Over 2-4 weeks of consistent use, this formula is designed to support healthier vitamin D intake, better calcium regulation, and the long-game aspects of performance and wellness: bone integrity, immune readiness, and proper musculoskeletal function. This is a simple formula, but it is simple in the right way.
