Hey sorry for my late reply. So instead of brands, I’d recommend picking any KSM-66 Ashwagandha extract (KSM-66 is a method of extraction), and any L-theanine. Make sure you include Pipperin in your stack because it’ll really increase bioavailability of what you take. I use Neowell Zen because it’s already mixed all that. However, on most days I’d take individual capsules since I want to control dosage of each. When I’m traveling or have to meet clients and speak, then Neowell Zen saves my time.
