Thymoquinone Stability
Original post in this thread

Is there any way to increase Thymoquinones stability?
If i order fresh nigella sativa it's always fairly potent but after a few month it looses most of it's potency.
Would maybe a singe freeze/unfreeze cycle hurt, or have any use at all?

I store it at room temperature, after about 2-3 month there is an significante drop in it's strength.
And yes, i'm talking about the powder.
Some studys seem to support my experience.

My lab director is saying that if you have a jar that you have had open for a few months, and you don't think is as potent, you can send it back to us and we can run it through the lab to confirm if degradation is happening. We'll obviously replace the jar for you.
