Vegan Vitamin D3

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. Plants, on the other hand, contain only very small amounts of the much less effective form of vitamin D2. However, years of research have recently led to the discovery of a completely plant-based source of vitamin D3: a multi-stage process, which includes the conversion of plant precursors into bioactive vitamin D3 and intensive purification, results in a D3 crystallisate with a purity of over 99%. This means we can now offer entirely natural and vegan vitamin D3 products with Sunferol® D3 Vegan.

All-Trans Vitamin K2

Vitamin K2 exists in various forms, which have different levels of effectiveness. Vitamin K2 MK-7 is considered by far the most effective form of K2 today, as it remains active in the body for a particularly long time and is able to cover the functional K2 requirement of the body in relatively small doses. However, since vitamin K2 molecules occur in a variety chemical structures (the so-called cis–trans isomers of vitamin K2), there are considerable differences in efficacy even between different vitamin K2 MK-7 compounds. It is believed that only the trans forms can be utilised by the body.

Vitamin K2 is designated "all-trans" when it consists of at least 98% trans isomers. Despite manufacturers' claims, widespread label fraud occurs in the sale of vitamin K2. Independent laboratory tests prove that many supplements declared as all-trans K2 often actually contain only small amounts of all-trans vitamin K2.

Our original Sunquinone® K2 is a branded active ingredient with a uniquely high MK-7 all-trans content of approximately 99.8% in the raw material. The consistently high purity is ensured by independent laboratory tests.

Absolute Purity: No Hidden Additives

Our branded active ingredients Sunferol® D3 Vegan and Sunquinone® K2 are specially manufactured for Sunday Natural – made from natural raw materials and with particular emphasis on purity and quality.

Conventional vitamin D3 + K2 active ingredients are often mixed with a whole range of questionable additives, including synthetic vitamin E, ascorbyl palmitate, silicon dioxide, modified starch, sucrose, denatured vegetable oils and maltodextrin. However, our active ingredients are specially manufactured according to our specifications, thereby avoiding such hidden additives. The purity of these raw materials means only a small amount of bioactive vitamin E needs to be added as an antioxidant to ensure optimal stability and shelf life.

To maintain the excellent quality of our products, they are regularly tested in an independent laboratory for active ingredient content, freshness and possible contaminants such as heavy metals.

MCT Coconut Oil for Optimal Absorption & Protection

Vitamins D and K2 are fat-soluble vitamins that can only be absorbed by the body when combined with fats. For this reason, Sunday Natural's vitamin D3 + K2 is suspended in high-quality MCT oil. In contrast to other carrier oils (such as olive oil), pure MCT oil offers optimal protection for fat-soluble vitamins, thus ensuring maximum stability of the active ingredients. The medium-chain fatty acids in the carrier oil constitute valuable nutrients themselves. Our oil, which is processed in the Netherlands, is grown without the use of synthetic plant protection products.

Simple & Precise Dosage

Oils are easy to use and are therefore suitable for those who have difficulty swallowing capsules and tablets. They also offer the advantage of direct absorption through the oral mucosa, meaning the fat-soluble vitamins are immediately bioactive. All our oils come in environmentally friendly amber glass bottles with a glass dropper for precise usage.
