Why is D | E | K | A so unique?

1. Synergistic Action - More than the Sum of Individual Vitamins
Vitamin D3 + K2: A classic combination that supports the absorption of calcium and its targeting to the bones, while preventing calcium build-up in the arteries.
Vitamin A supplement: improves immune function, supports skin, eye and mucous membrane health, which vitamins D and K alone do not provide.
Vitamin E: Acts as a powerful antioxidant, protecting cells from oxidative stress and increasing the stability of the formulation, as vitamin E protects other vitamins from oxidation.
2. Better Absorption with MCT Oil
Vitamin D alone, or the combination D + K, is poorly absorbed in the body without the presence of fat. Our advanced MCT oil base from coconut allows for 3x better absorption of all fat-soluble vitamins. This ensures immediate and efficient delivery of nutrients to the body.
3. Clinically Proven Effects and Tested Formulation
Clinically supported purity: our K2VITAL® MK-7 provides 99.7 % all-trans formulation, which means the highest purity and biological activity compared to generic formulations on the market.
All ingredients are lab-tested, free from gluten, soy, palm oil or artificial additives.
4. Total Body Support
Vitamin D3 + K2: Supports bone health, muscle function and a healthy cardiovascular system.
Supplement A + E: Promotes skin health, eye protection and a stronger immune response - something that typical vitamin D or D + K do not provide.
5. Scientifically Supported Formula
Developed by a team of experts led by Dr Tina Prodnik, who specialises in functional medicine and nutritional science.
Manufactured according to the strictest EU standards (GMP, ISO 22000:2018).

Compared to products containing only vitamin D or a combination of vitamin D + K, our D.E.K.A. ensures integrity thanks to:

The synergy of four vitamins:
