How sensitive to heat? Left on doorstep over 36 hours summertime in Texas in 100F temperature for 6-10 hours. Is this bottle no longer effective?

I'm really not too sure as to the effect the heat would have. I would personally try to get another bottle.

so does this mean any mk7 in other formulas is not trans? has anyone found these claims to be true?

Hello, Unless their supplement fact panel specifies All-Trans or Trans version it is extremely likely they are not using a trans version. Best Regards, -Reese Double Wood Supplements

what kind of MCT is the carrier oil?

The only thing it lists is medium chain triglycerides

Good product

Comes quickly. Been using this product for over a year and will continue to use it. Doesn't taste awful but not great tasting either. Easy to use. Doesn't bother my stomach. I use this in combination with other vitamins & minerals that work together for optimum absorption.

Feeling Good with These Drops!

Gotta say, these Vitamin D3 K2 liquid drops seem pretty good! The liquid form is easy to take, and I like that it has both D3 and K2. Hopefully, it's helpin' boost my levels. No weird taste or anything. Thumbs up so far!

All good - easy to use - tasteless

Only been taking 1 week- 1 dose daily plus another 5k capsule. So far ok. The taste is negligible- no issues with intake

Great solution for those of us tired of choking down pills

I love this. I have issues swallowing pills so this is perfect. I just drop the recommended amount on top of my morning coffee or in a smoothie and I’m good to go. My vitamin D tested low at the doctor’s office so I tried this. When they tested again several months later my vitamin D level was on target. Okay, so it doesn’t taste great if you just put the drops in your mouth, but I don’t notice it at all on top of my coffee or in a smoothie. I love this and subscribed so I don’t run out.

Ok taste will break you out

I like this product. The taste is ok. I bought it because of the quality of the ingredients. Its unfortunate that taking the recommended dose is wreaking havoc on my skin. I broke out badly so I'm no longer taking it.

Great value.

I need Vitamin D to treat lupus. Vitamin K2 (great for your bones and teeth), helps my body absorb the Vitamin D.These drops are easy to use, easy to measure (I need to take a very large dose), tasteless (I just put two droppersful into a shotglass of water and down it, but you could stir this into anything and not taste it, or even just take it straight). It's well packaged, and arrives on time, every time.Best of all, it's affordable.
