Vitamin D&K Mix  - Unflavored  Powder

The Fringe D&K Powder contains water-soluble vitamin D3 from lichen. Traditional Vitamin D3 supplements are made from lanolin or sheep’s wool. This is not suitable for vegetarians or vegans as it is animal based and the process can be quite chemical. We’ve sourced our D3 from lichen - living organisms which consist of fungus combined with algae. Lichen makes D3 following exposure to UVB rays - just like us!

Fringe DK powder contains vitamin K2 in the form of MK-7, the most

bioavailable form of vitamin K. It is derived from the fermentation of Nattō, which

is plant-based and suitable for vegan diets.

This is a soluble fiber derived from chicory root. It helps to maintain accurate dosing with the product.

Helps facilitate the solubility and bioavailability of vitamins D and K.

Helps dissolve, dilute, and accurately dose vitamins

A compound naturally found in fruits, beans, and grains that also helps keep each scoop consistent.

We asked questions about Vitamin D (and K) and we didn’t like the
answers, so we made a product with better (cleaner, more fun, more
sheep-friendly) answers. Read on amigos!

There are two forms of vitamin D that are found in dietary supplements, vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is sourced mainly from animals, although lichen is a vegan source of D3. Vitamin D3 is the form made in humans following exposure to UVB light. In contrast, vitamin D2 is sourced from plants.

Vitamin D3 is largely recognized as being more “bioavailable”, meaning more of the vitamin that is ingested gets delivered to body tissues. Studies that directly compare the bioavailability of D3 to D2 show that vitamin D3 raises blood levels of 25-hydroxyvitamin D more than vitamin D2, so it is preferable to choose a supplement containing vitamin D3. If you are vegan, choose a supplement that contains D3 sourced from lichen.

There are also two forms of vitamin K, vitamin K1 (phylloquinone) and vitamin K2 (menaquinones). Vitamin K1 comes mainly from plants, while vitamin K2 is made by bacteria and is found in animal-based and fermented food. Vitamin K2 is further subdivided into MK-4 through MK-13. Each of these subgroups of vitamin K2 has a slightly different molecular structure. Dietary supplements usually include MK-4 or MK-7. MK-4 occurs naturally in foods including liver, butter, and cheese, while MK-7 is made through fermentation, with the best source being Japanese fermented soybeans (called Nattō). Studies have shown that vitamin MK-7 is more bioavailable than vitamin MK-4, so it is preferable to choose a supplement containing vitamin MK-7.

Vitamin D supports bone health, muscle function, immune function, and mood. It also helps your body absorb calcium. Want the research? Check out our blog.

Vitamin K2 helps direct calcium to your bones and supports healthy bone mineralization. It also plays a role in normal blood clotting and supports heart health. Read more on our blog.

Our D3 and K2 come in a water-soluble form, making them more bioavailable, and you can mix them into any drink and take them with or without food.

1 scoop (2,500 IU vitamin D3) per day. Take more only if your provider recommends it based on your levels.

Vitamins D and K are generally well tolerated at normal doses. Get your vitamin D levels checked regularly, and talk to your provider if you take medication, especially blood thinners.

We third-party test every batch for heavy metals, mold, and pesticides. See the results.

We sure do! Safety is our number one priority when it comes to supplements. We third party test every batch of Fringe supplements for heavy metals, mold, and pesticides. And we publish the results! Check out our mission and testing results here.

Scientific studies are all over the map with optimal range recommendations ranging from 20ng/mL - 60ng/mL. Our advice is to work with a health care provider who can monitor your blood vitamin D levels and tailor recommendations accordingly.

Whenever you will be consistent! Time of day doesn’t matter with taking vitamin D, but what does matter is making sure your body gets these essential vitamins in on a daily basis.

Not ours! Because Fringe DK powder is water soluble, you can take it on an empty stomach or with a meal, whichever you prefer.

Yes. It’s not common, but it’s possible, especially at high doses over a long time. Too much vitamin D can raise calcium levels in the blood. That’s why we recommend checking your levels with your provider, especially if you take more than 1 scoop a day or get vitamin D from other supplements.

There is no recognized upper limit to the amount of vitamin K1 or K2 that can be consumed. The Office of Dietary Supplements states that “no adverse effects associated with vitamin K consumption from food or supplements have been reported in humans or animals”. A synthetic form of vitamin K, called menadione, has caused toxicity in infants, but in the US this form is generally only used at present in animal food.

Important: if you take a blood thinning medication, talk to your provider before taking any vitamin K supplement. Vitamin K affects how those medications work.

While calcium plays a critical role in many body processes and works alongside vitamins D and K, the verdict is still out on how effective calcium supplementation is. While it’s an essential mineral for sure, it should be primarily obtained from foods such as dairy, almonds, and sardines. Natural water like mineral water is also an amazing source of calcium! And the great news - our newly formulated electrolyte/mineral powder has calcium - check it out here.

If you consume very little calcium in your diet, taking a supplement may be warranted. However, be aware that many calcium supplements are dosed high (500–1000 mg per serving). If you’re considering one, talk to your provider about how much you actually need.

Yes! Magnesium is another nutrient that is interacts with vitamin D. Many enzymes that synthesize and metabolize vitamin D are dependent on magnesium for proper functioning, so optimal magnesium status is important for vitamin D. Most people do not consume sufficient dietary magnesium, and due to depletion of magnesium from our soil and foods, supplementation may be necessary to meet our daily needs. Lucky for you - we have an amazing magnesium supplement as well - check it out here.

Just like adults, kids can be low on vitamins D and K as well - especially if they aren’t eating foods high in these nutrients or outside often. Kids can also take Fringe Vitamin D&K Mix. As always, consult with your pediatrician or healthcare provider before beginning any new supplement. Doses by age are in the next question.

Always consult your pediatrician or healthcare provider before beginning a new supplement. Based on age, the recommended doses are: for children aged 2-3 years old, ¼ scoop per day; ages 4-8, ½ scoop per day; ages 9-13, ¾ scoop per day; ages 14+, 1 full scoop per day. As with adults, the only way to know for certain how a child is responding to supplementation is to have their blood tested. For children under 1 year of age, please consult a health care provider before using.
