ADK Evail™

Fat-Soluble Vitamin Complex

A synergistic blend of vitamins A, D, E, and K to support a healthy fat-soluble vitamin balance in the body and to promote bone, heart, and immune health.*

ADK Evail™ is a fat-soluble vitamin supplement by Designs for Health that delivers 5,000 IU of vitamin D3 per serving, along with vitamins A, K1, K2, and vitamin E tocotrienols, which are part of the vitamin E family, in one convenient softgel.* It uses patented Evail™ technology, which helps fat-soluble nutrients mix for better absorption, to promote maximum nutrient absorption for bone, heart, and immune health.*

ADK Evail™ is formulated to support bone strength, along with healthy immune function, by combining synergistic fat-soluble vitamins.* Vitamin D3 supports calcium regulation, while vitamin K2 helps direct calcium into bones and teeth.* Results may vary based on diet, sun exposure, and overall health status.*

Key benefits include support for bone and teeth strength, immune system function, heart and artery health, skin and nail maintenance, and antioxidant status.* These benefits are driven by the synergistic combination of vitamins A, D3, K1, K2, geranylgeraniol (GG-Gold™), a compound that supports the body’s natural vitamin K2 production, and DeltaGold® tocotrienols.*

Take one softgel per day, ideally with food, or as directed by your healthcare practitioner. ADK Evail™ is formulated with Evail™ technology for enhanced absorption. Consult your practitioner before use if you are taking Coumadin, warfarin, or other blood-thinning medications, as vitamin K may interact with these drugs.

ADK Evail™ contains vitamin D3 (5,000 IU) to support calcium regulation, vitamin A (as retinyl palmitate) to support vision and cell health, vitamins K1 and K2 (as MK-4) to promote bone and arterial support, geranylgeraniol (GG-Gold™), a compound that supports K2 production, and DeltaGold® tocotrienols to promote antioxidant status.*

You may experience improved support for bone strength, immune resilience, and overall well-being with consistent daily use.* Fat-soluble vitamins build up gradually, so benefits develop over weeks of regular supplementation.* Results depend on baseline nutrient status, sun exposure, diet, and practitioner guidance.*

ADK Evail™ is designed for daily use when taken as directed.* It uses Evail™ technology, which helps fat-soluble nutrients mix for better absorption and is free from petrochemicals or synthetics.* Consult your healthcare practitioner before use if you are pregnant, nursing, taking blood-thinning medications, or managing a health condition.*

ADK Evail™ goes beyond standalone vitamin D by combining all four fat-soluble vitamins — A, D, K, and E — in balanced ratios within one softgel.* Its patented Evail™ technology, which helps fat-soluble nutrients mix for better absorption, uses quillaja extract and GG-Gold™ to enhance absorption, making it ideal for individuals who have difficulty absorbing fat-soluble nutrients.*
