BIOGENA SPORTS D3 & K2 Liquid delivers two essential fat-soluble vitamins in one convenient drop, formulated for the increased demands of active training.
Each serving provides 2,000 IU of vitamin D3 and 25 µg of vitamin K2, working together as partners: D3 supports calcium absorption, while K2 helps direct that calcium to the bones, contributing to the maintenance of normal bones.
Vitamin D also supports normal muscle and immune function, both essential for performance and recovery.
The K2 comes as K2VITAL®, a premium MK-7 form with at least 99.7% purity, known for its high bioactivity and long circulation in the body.
Both vitamins are carried in MCT oil from coconut for fast, efficient absorption.
Made in Austria, the formula is vegan, sugar-free, free from unnecessary additives, and listed on the Cologne List®, which independently screens supplements for banned substances.

Frequently Asked Questions
Why are vitamin D3 and K2 combined together in BIOGENA SPORTS D3 & K2 Liquid?
BIOGENA SPORTS D3 & K2 Liquid pairs these two fat-soluble vitamins because they function as partners rather than standalone nutrients.
Vitamin D3 supports calcium absorption from the gut, while vitamin K2 helps direct that calcium toward bone tissue — together, they contribute to the maintenance of normal bones, which is why Biogena delivers them in a 2:1 ratio rather than separately.
How and when should I take BIOGENA SPORTS D3 & K2 Liquid?
Take one drop daily, either directly under the tongue or mixed into a drink or food, ideally at the same time each day to build a consistent routine.
BIOGENA SPORTS D3 & K2 Liquid is designed for daily, year-round supplementation across every training and performance phase, not just as a short-term or seasonal supplement.
Is BIOGENA SPORTS D3 & K2 Liquid suitable for vegans, and is it safe for everyone?
Yes — BIOGENA SPORTS D3 & K2 Liquid is 100% vegan and sugar-free, with no animal-derived ingredients.
That said, it isn't suitable for children under 11, and anyone taking anticoagulant medication should consult their doctor before use, since vitamin K2 plays a role in normal blood clotting.
What makes the K2 in BIOGENA SPORTS D3 & K2 Liquid different from other vitamin K supplements?
BIOGENA SPORTS D3 & K2 Liquid uses K2VITAL®, a branded raw material providing menaquinone-7 (MK-7) — widely considered the most bioactive and longest-circulating form of vitamin K2 — at a guaranteed purity of at least 99.7%.
Combined with an MCT oil carrier for enhanced absorption, this gives the formula an edge in bioavailability over standard vitamin K2 products.
