Tại sao Sunday Natural khác biệt?

Why is Sunday Natural different?

Vitamin D3 is found almost exclusively in animal products, meaning that the vitamin D3 found in supplements is usually obtained from raw materials such as sheep's wool, fish oil and shellfish. However, years of research have recently led to the discovery of a purely plant-based source of vitamin D3, meaning we can now offer entirely natural and vegan vitamin D3 products.

All of our vegetarian and vegan vitamin D products contain premium vitamin D3 as an active ingredient, which is custom-made according to our strict specifications, and without any additives except vitamin E and a high quality MCT coconut oil as a carrier oil. This product is notable for its absolute purity and guaranteed vitamin D3 content. Vitamin D3 products often contain a wide variety of different additives, including some which are highly questionable but are not legally required to be declared, such as synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starch, sucrose, denatured vegetable oils, and maltodextrin. However, our vitamin D3 is ultra pure due to our unique production process. It is custom-made for us by a specialised manufacturer according to our strict specifications and is completely free from common hidden additives.


We also use premium bioactive K2 MK7 all-trans by Norwegian brand Kappa, a leading producer in Europe. It is one of the few commercial supplements on the market that consists of 100% highly effective all-trans MK7. Impurities and fluctuations in quality among batches are therefore not an issue.


MCT Coconut Oil for Optimal Absorption


Vitamins D and K2 are both fat-soluble vitamins that can only be absorbed by the body when combined with fats. Sunday Natural Vitamin D3 + K2 is dissolved in high-quality MCT oil for optimal bioavailability and can therefore be directly utilised by the body. In contrast to capsules and tablets that must first be digested in order for their active ingredients to be released, vitamins D3 and K2 combined with oil are readily available and can be optimally absorbed. Our MCT coconut oil is completely free from additives and the medium-chain fatty acids in the carrier oil constitute valuable nutrients themselves.


Oils are easy to use, and are therefore suitable for those who have difficulty swallowing capsules and tablets. All our oils come in amber glass bottles with a high-quality glass dropper. In contrast to dispensing bottles, which are often difficult to use and clog easily, glass droppers are ideal for precise usage.
