Product Summary

The Thorne Vitamin D/K2 liquid drops are a convenient way to add both vitamin D3 and vitamin K3 to your nutritional regimen. Two drops deliver 25 micrograms (1,000 international units) of vitamin D3 and 200 micrograms of vitamin K2 which can easily be mixed into any beverage without altering the flavor. Together, these vitamins are said to support bone, muscle, cardiovascular, and immune health.

Thorne products go through four rounds of testing to ensure accurate dosage and quality formulation: raw material testing, in-process batch testing, finished product testing, and expiration date stability testing. Their supplements are clean, making it a good choice for anyone who avoids artificial ingredients and unnecessary fillers.

The Vitamin D/K2 liquid comes in a small bottle which contains 600 servings. Needless to say, if taken appropriately, this will last a long time. There are some users who find the self-dispensing top finicky, which could affect dosing. You may simply need to keep the bottle upside down and let gravity do its thing to get the drops out.
