liquid k2

Examples in listings show vitamin D3 commonly at about 2,000 IU per serving. Vitamin K2 varies more widely — often in the tens of micrograms (roughly 50–80 µg), commonly up to ~200 µg per serving, and some concentrated options list about 1 mg (1000 µg) per drop.

Several liquid formulas use MCT oil as the carrier — examples list organic MCT oil or MCT coconut oil as the oil base for suspending D3 and K2.

Listings include both MK‑7 (menaquinone‑7) and MK‑4 forms of vitamin K2. MK‑7 is noted in several products, and at least one concentrated option specifies MK‑4 per drop.

The core combination is vitamin D3 with vitamin K2. Some formulas also include other active ingredients such as CoQ10 alongside D3 and K2.

Product descriptions commonly link D3+K2 liquids to bone support and calcium absorption/balance, cardiovascular or heart health, and some listings also mention immune support or muscle health.
