## Questions & Answers

**Q: Hi,  What is this made from?   Thank you😊**
A: I would like to know this answer to, whether it’s synthetic or natural source. But my big question is why people feel the need to answer a question; sorry to say, stupidly. “I don’t have it anymore” okay, so why do you feel the need to answer this question then? I see sooo many countless, meaningless answers over many products. Do these folks really have so much time on their hands?!? Unless you have something meaningful to contribute what’s your need to answer? This is the same with social media- we don’t care.

**Q: How much silicon dioxide is in 1 pill?**
A: The amount is not listed

**Q: What is the source this is made from?**
A: The bottle indicates 90 vegetarian capsules, with a somewhat long list of stuff it does not contain like non-vegetarian ingredients, tree nut, peanuts, wheat, gluten, soybeans, corn, yeastand artificial colors, flavors or preservatives.  Apart from that, no word about what it is made from.  Sorry.

**Q: are the capsules suppose to be yellow?**
A: I never took K2Mk4. K215mg or 15.000mcg is white
