What to know before buying
Listing details to confirm
Follow the serving instructions on the product label or a healthcare provider's advice. The listing states 5,000 IU D3 and 100 mcg K2 per half dropper, but the listed package dimensions include a weight of 0.1 ounces, which may describe packaging rather than supplement contents. Consider customer reports of mixed taste and tolerability when choosing a liquid supplement.
Who is it for?
A good fit for

- Those seeking a formula listing coconut MCT oil and a mint flavor.
Less suited to
- People who prefer an unflavored supplement or want to avoid mint taste.
