I want to buy all of my supplements from Nootropics Depot because of their unparalleled attention to safety. For this reason, I'd like to request ND carry more supplement basics like vitamn D, K2, C, etc. Thanks.

Not sure you've heard of innovix labs K2? It's a mix of mk4 mk7 with no k1. But what made me buy it was this:
>Trans MK-7 - the form found in nature
-MK-7 comes in two forms - CIS and TRANS. Some supplements are a mix of CIS and TRANS
-CIS form is not nature-identical and may have limited activity
-TRANS form is found in nature and foods and is recognized and absorbed by the body
-InnovixLabs contains TRANS MK-7
Only brand is seen that advertised this property. I've been taking this for a few years but didn't know if it really mattered or was accurate etc.

Yeah, you want to have the trans isomer. We have a polarimeter in our lab we use to make sure the optical rotation meets specs. That's only for R and S, though. Cis and trans is more complex.
I know Innovix Labs claims to have all trans, but do they give any testing results proving that? It's easy to just say you do. It's a lot harder to prove it every batch. 99% of the time I find these vendors don't test isomers/enatiomers at all.
