Recommend for better sleep and vertigo
I have been taking some expensive cortisol supplements from a med spa and wondered how these would do after getting used to the results I had with the other ones. I have to say, they have worked great for me. I have been falling asleep and staying asleep SO much better! Plus, I was in a state of vertigo for months and it’s completely gone now! I have nothing else to credit but these supplements, so apparently they’re working nicely. I have been in them about a month. No negative side effects
