- It allows the immune system to function optimally and maintains cell vitality.
Did you know?
Vitamin A was the first vitamin to be discovered and is therefore named A. Today we know that it is essential for our vision, immune system strengthening and healthy skin.
+ MCT oil
Fat-soluble vitamins can only be absorbed effectively in combination with fats. For our formulation, we have chosen a premium MCT oil derived from coconut oil as the carrier oil.
MCT oil provides better stability of fat-soluble vitamins compared to other carrier oils such as olive oil or tablet fillers such as calcium carbonate. Due to its stability, it protects the vitamins and preserves their bioactive activity. In addition, the medium-chain fatty acids in MCT oil are a valuable nutrient in their own right.
CORRECT:
- Improves absorption of fat-soluble vitamins: MCT oil provides better bioavailability
Vitamins A, D, E and K. - Ensures formulation stability: protects vitamins from degradation and preserves their effectiveness.
- Rapid metabolic action: directly absorbed by the liver without the need for lymphatic transport,
which ensures a rapid effect. - Natural health support: medium-chain fatty acids contribute to the body's energy support.
- Convenient and easy to use: MCT oil drops are suitable for everyone, including those who
have difficulty swallowing tablets or capsules.
Did you know?
MCT oil is rapidly metabolised and efficiently converted into energy by the body, providing support without fat storage.

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:
Combination D3, K2, A and E can work in concert to:- Effective support for the immune system,
