I genuinely have never experienced a 100 Garmin body battery score until I started using ainslie + ainslie Day and Night powders.

I was cynical but I am really, really impressed. My muscle recovery and mental clarity have vastly improved since taking this supplement.

My average sleep score rose by 10 points and my average HRV rose by 5 points. After 2 weeks I committed to a subscription.

I'm not a professional athlete but I honestly have needed the stamina of one. This is a brilliant, brilliant product.

I'm always cautious with supplement claims, but I noticed an impact immediately backed up by Garmin data. Quality of sleep and recovery markedly improved.

Suffered with insomnia since I was a child. There is nothing I have not tried. One week in and it works. I am sleeping. Utterly amazed.

I sleep deeper, more time in core and deep sleep, and my resting heart rate has dropped from 70 to 58 bpm. Highly recommended.

My Garmin sleep score went from an average of 48-60 to 80+ almost immediately. Best thing is it has stayed there.

I've suffered with poor sleep all through my adult life. This is a game changer. I've slept so well from day one and every night since.

From sleepless nights with a young family to hormonal changes in my forties, I haven't slept well for years. That is until now.

I couldn’t recommend the ainslie and ainslie products more. Probably the best supplements I’ve taken.
