K for Koagulation

Vitamin K was discovered in 1929 by the Danish biochemist Henrik Dam. He named the substance after the German word Koagulation, clotting. In 1943 he received the Nobel Prize for it. It later turned out that there are several forms; these drops contain menaquinone-4 (MK-4).

Selected by Ergomax

12.5 µg vitamin D3 and 50 µg vitamin K2 per drop, for adults and children from 1 year. Handy if you don't swallow capsules or want to fine-tune the dose.

Adults no more than 8 drops a day, children 1 drop. If you use blood thinners, consult your doctor first, as vitamin K affects blood clotting.

About the brand

Seeking Health, briefly explained.

Seeking Health

Nutrition that fits your genes.

Seeking Health was founded by Ben Lynch, naturopathic doctor and author of Dirty Genes. He studied at Bastyr University in Washington and has worked for years with doctors and health professionals who apply insights from epigenetics. His starting point: your genes are not a fixed fate, and with diet and lifestyle you can work with them. Seeking Health is best known for active forms of vitamins, such as methylfolate and methylcobalamin, and for methyl-free variants for those who are sensitive to them.

Quality and production

Active forms, clear choices.

Seeking Health opts for vitamins in the form in which the body uses them and offers a methyl-free variant of many formulas. The products are made in the United States according to GMP and are free of the most common allergens.

Forms
INFO
Active vitamins
Methylfolate, methylcobalamin, P-5-P
Wherever possible, Seeking Health uses vitamins in the form the body can use directly: folate as L-methylfolate or folinic acid instead of folic acid, vitamin B12 as methylcobalamin, hydroxocobalamin or adenosylcobalamin and vitamin B6 as pyridoxal 5-phosphate.
Choice
INFO
Methyl or methyl-free
MF variants without methyl groups
Not everyone tolerates formulas with methyl groups equally well. That is why Seeking Health offers an MF variant, methyl-free, of many products, with folinic acid and hydroxocobalamin, for example. That way you can choose what suits you.
Purity
INFO
Without common allergens
No gluten, dairy or soy
The formulas are free of gluten, dairy and soy and contain no artificial colourings or flavourings. The label of each product states which allergens may be present, such as milk in a whey protein.
Production
INFO
Made in the USA
According to GMP
The supplements are produced in the United States, in facilities that work according to GMP, the guidelines for good manufacturing practice.
