Your drive is the same.
Your energy isn't.
Somehow, your energy isn't matching your ambition anymore, despite trying harder than ever to "do everything right."
– Waking up refreshed feels impossible
– Afternoon crashes are the new normal
– Mental fog hits by 2pm
– Late nights = three-day recovery
"I was running on absolute fumes, even though I was living healthier than I ever had in my twenties.
So, I looked to my husband (4x Olympic Gold Medal winner, Ben Ainslie) and what he was doing differently to the rest of us."

You don't know you're under-recovered until you feel what real recovery is.
Life Changing.
The benefits to my overall well-being have been nothing short of game changing. A more mellow me, with better sleep than I have had for years, and the mojo is returning too!!

I didn't really think I had issues with sleep.
After two friends raved about NIGHT POWDER, I decided to try it. After a fortnight or so, I noticed I was falling to sleep quicker and sleeping through to my morning alarm. I am surprised I didn't do anything to address it before.
Macia A
Utterly amazed, as I have tried everything!
There is nothing I have not tried. I have been taking A and A for a week and it works! I am overwhelmed! I am sleeping! Utterly amazed, especially as it is natural, not chemical.

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

Tried the 7 day option and went immediately...
Tried the 7 day option and went immediately to the subscription, my sleep quality has improved immensely and I'm more awake and alert the next day. I also feel more recovered from my previous day's training. Fantastic product!

Can't recommend the product enough.
I am a working mum juggling a business and a young family. I can’t recommend the product enough. I’ve recommended the product to clients as I work with women who have demanding professional careers and lives as well as friends.

Sleep Quality Improves!
I have sleep problem for years and nothing works, including melatonin. Came across this accidentally and told myself no harm trying. To my surprise it works! My sleep quality definitely improved within a week as revealed in my Garmin sleep scores.
