What should I know about vitamin k2 tropfen dosierung wirkung und kauf?

Vitamin K2 (menaquinone) is commonly sold as drops. Dosage depends on the product and goal (e.g., bone health, vascular protection); typical doses are 45–100 µg MK‑7 per day. K2 activates proteins that bind calcium into bone and keep it out of arteries. Evidence is mostly mechanistic and observational; no large RCTs specifically on K2 drops exist. For purchase, look for all-trans MK‑7 from reputable brands. None of the provided sources address K2, so this answer is based on general knowledge. Caveat: K2 can interfere with blood thinners (e.g., warfarin) – consult a doctor before use.
