What Is D-Evail Supreme (Vitamin D Supreme)?
D-Evail Supreme is Designs for Health’s high-potency vitamin D3 softgel formula delivering 5,000 IU per serving alongside vitamin K1, vitamin K2 as MK-4, and geranylgeraniol — all in DFH’s proprietary Evail lipid-based delivery system for enhanced absorption. Vitamin D3 at therapeutic doses is one of the most clinically supported nutrients for immune function, bone density, mood, and cardiovascular health, and pairing it with K vitamins ensures proper calcium utilization in the body. Each bottle contains 60 softgels.

Who Should Take This?
D-Evail Supreme is ideal for patients with confirmed vitamin D deficiency or insufficiency, those in northern climates or with limited sun exposure, individuals with malabsorption conditions, patients on statin medications (due to the geranylgeraniol), and anyone seeking a high-potency D3+K formula with optimal bioavailability. Our doctors may recommend lab testing to monitor vitamin D levels when using therapeutic doses.
How to Use
- Serving size: 1 softgel daily, or as directed by your healthcare provider
- Timing: Take with a meal containing healthy fats to further enhance absorption
- Duration: Consistent daily use is recommended; retest vitamin D levels after 3 months

Our Doctors’ Take
Our doctors consider vitamin D one of the most impactful foundational supplements, and D-Evail Supreme represents one of the highest-quality D3+K formulas we’ve found. The Evail delivery system meaningfully improves absorption compared to standard capsules, and the inclusion of both K1 and K2 as MK-4 — plus geranylgeraniol — makes this a more complete formula than most vitamin D supplements on the market. If you’ve been told your vitamin D is low or you haven’t been tested recently, this is a great place to start.
