Good for sleep and focus
I usually take one in the morning with some coffee and I noticed some improvement in my focus during the first half of the day.
Also take before bedtime, only some nights to improve sleep quality and it makes me feel better rested and I would say it improves my overall sleep.

This is great product , sleep or training
I am using it successfully for both purposes and it’s working as expected . I can ease the mind before sleep . When I am working out it gives the serenity to execute with clearer mind.
