Thorne Research - Vitamin K2 Liquid (1 mg/drop) - Concentrated Vitamin K2 Supplement - 30 ml International Direct

Q: How many servings is in the 1 oz bottle?

I noticed a large discrepancy in the two answers already given, so I'll try to clarify the confusions. The label states (not "drops" but "servings") "Servings Per Container: 80" and also states "Serving Size: Fifteen Drops" and "Fifteen Drops Contain: Vitamin K (as Vitamin K2 Menatetrenone) 15mg". So at the rate of 45mg/day, the 1200 drops/bottle would indeed last 26+ days or about a month; however the math at 5 drops/day would last 240 days or about 8 months. While some may use as little as 1 or 2 mg/day, at my actual use rate of 7drops/day a bottle has consistently lasted just under 6 months which fits with the math that works out to 171+ servings. Hope this helps!

Q: Is the K2 the MK4 version?

In response to another question: "Both vitamin K2 supplements are nearly completely absorbed, with peak serum concentration at 2 hours for MK-4 and 4 hours for MK-7 after intake. Originally, the most compelling research was on high-dose MK4. More recently, some interesting MK7 research has been conducted and published. Therefore, Thorne is working on a combination product that should be available in 2016. Any studies looking at increased bone density are typically long range studies."

Q: To cover all bases, wouldn't combined mk-4/mk-7 be best? considering in one mk-7 study (180 mcg daily) it took up to 3 years to see density improve.

Q: What is the expiry date on the bottle? In other words, what is the shelf life?

My last two bottles had expiration dates about a year out.Good stuff--helped repair my teeth--good luck.
