Company details
About ainslie + ainslie
Written by the company
The story of ainslie + ainslie NIGHT POWDER began in 2020, when during the Covid pandemic Sir Ben Ainslie’s sailing team, were required to compete in the 36th America’s Cup in New Zealand. Getting there, operating there, performing there meant no one could afford to get sick. The athletes were provided with a supplementation programme to support sleep and optimise recovery. Working with the body’s natural circadian rhythms to boost immunity and maximise performance the athletes had what they needed, when they needed it most.
Ben’s wife, the broadcaster Georgie Ainslie, saw this approach first-hand and it raised a question.
If this worked in the toughest of sporting environments, where athletes are required to be both mentally and physically sharp in order to work, train and compete day in, day out, then why couldn’t it work for the rest of us too?
After all, it’s not just elite athletes who care about performance. We all have our own standards we want to hit daily and too often we are trying to do that on rubbish sleep and poor recovery.
Ben and Georgie could see how sports science-led thinking and supplementation could benefit anyone who wants to feel and perform better.
It is designed for athletes but it’s made for everyone.

Hi Gary,
Thank you for taking the time to share your experience - we’re really pleased to hear that NIGHT POWDER has helped you fall asleep more quickly. That’s one of the first benefits many customers notice, with 73% of our trial participants reporting they got to sleep more easily after just one week.
Waking in the early hours can happen for a variety of reasons, and it’s great that you’re planning to keep going a little longer to see how things progress. Many people find the deeper, more consistent benefits build gradually over time with continued use.
We really appreciate your feedback and hope you continue to see improvements over the next few weeks.

Hi there,
Thank you so much for your lovely review - we’re delighted to hear you’re loving both NIGHT POWDER and DAY POWDER and noticing such a big improvement in your sleep. It’s fantastic that you’re sleeping through the night more easily and waking up feeling refreshed - that’s exactly what we love to hear.
Feeling like more of a morning person is such a positive change, and we’re so pleased the products have helped support that shift in your routine and energy.

From Bear Williams
I couldn’t recommend the ainlee and ainslee products more. Probably the best supplements I’ve ever taken. The daytime product I’ve taken every morning tastes amazing, gives me soo much energy to train and my immune system hasn’t felt better. The night time supplement has given me the best sleep and really helps me to recover around rugby training so I can perform at the best of my abilities. I really feel the night time product gives me the best deep sleeps.

Hi Bear,
Thank you so much for your fantastic review - we’re thrilled to hear that both NIGHT and DAY POWDER have made such a difference for you. It’s great to know the DAY POWDER is giving you the energy and support you need for training, and that you’re feeling the benefits to your immune system too.
We’re especially pleased that NIGHT POWDER is helping you achieve more restorative sleep and aiding your recovery around your rugby training - those are exactly the results we hope our customers experience.
We really appreciate your recommendation and are so glad to hear how well the products are working for you.

We really appreciate you taking the time to share this feedback.

Hard to know if it makes any difference
The taste isn’t bad, although a bit sweetener-sweet. It’s a good little measure to take twice daily and the pot and stirrer are cute to use. I had to give 3 stars because I’m not sure if it does what it professes to do. I would have liked to give it longer but the cost is prohibitive unless I can feel a huge difference.

Hi Pip,
Thank you for taking the time to share your feedback - we’re glad to hear you’re enjoying the taste of NIGHT POWDER + DAY POWDER and the premium accessories like the scoop and shaker, though we understand the sweetness isn’t for everyone.
It’s completely normal not to notice significant changes after just a few weeks. Many customers find that the benefits build gradually with consistent use. In our NIGHT POWDER consumer trial, 73% of participants reported they got to sleep more easily after 1 week, rising to 92% after 12 weeks, and in our DAY POWDER trial, 74% felt less tired after 1 week, increasing to 92% after 12 weeks.
We understand that cost is an important consideration, and we really appreciate your honesty. If you are able to continue for a little longer, we hope you might notice some of these benefits for yourself. Please do keep us updated on how things progress.

Many customers find that the benefits build gradually over time with consistent use. In our consumer trial, 73% reported they got to sleep more easily after 1 week, rising to 92% after 12 weeks, so it can take a little longer for the full effects to develop.
We really appreciate you giving it a try and hope you might continue to see if things begin to improve. You could also try taking NIGHT POWDER around two hours before bed to help reduce night waking. Please do keep us posted on how you get on.

Would definitely recommend, great product backed by great service.
I initially bought the NIGHT powder to see if it would help with my sleep. I have not slept great for some time now and recently I have taken up more exercise and healthy eating and to ensure good sleep was the element that still eluded me.
After about a week of use, I found that my sleep improved in every way. Speed to drop off, quality of my sleep and duration of my rest.
I also used the DAY powder sachets that came as a sample with my order and once the samples had ran out I missed them and therefore I added the DAY powder to my order.
There was a problem with my delivery and Gemma from the Customer Service team was amazingly helpful and she sorted things for me with a very helpful attitude.
Needless to say I am now subscribing to both DAY and NIGHT powder and I love the way it makes me feel.

Hi David,
Thank you for taking the time to share your experience - we really value your honest feedback. We’re sorry to hear you haven’t enjoyed the taste of NIGHT POWDER and that you’re not noticing benefits just yet.
The natural sweetness of NIGHT POWDER comes from steviol glycosides and natural flavourings. We know taste can be quite personal, so we understand if it’s not quite to your preference.
When it comes to sleep and recovery, many customers report improvements after consistent use over a longer period of time. In our consumer trial, 73% noticed they fell asleep more easily after 1 week, rising to 92% by 12 weeks - so the benefits can take time to build.
We hope you might continue a little longer to see if NIGHT POWDER makes a difference for you, but we truly appreciate you giving it a try and sharing your thoughts.

Excellent product. Excellent customer service.
Since increasing my exercise regime I have been looking for a product to help support my recovery. The day and nighttime powder certainly seem to have helped. Most noticeable is my improved sleep - longer sleep and better quality.
Equally impressive is the customer service who were helpful and prompt in sorting out a query. Everything fully sorted in a friendly and efficient manner. I will definitely be continuing to use the products.

I used this powder to see if it helped me rest whilst climbing at high altitude in the Himalayers. It is always difficult to sleep and rest for many different reasons. I found that it worked a treat and I managed to sleep better which meant that I was much stronger on my climbs than I used to be! This is a great product

Unreliable
The Night Powder tastes really nice, so it's pleasant to drink. I am Menopausal and I can get to sleep ok but wake up too early on a regular basis. The first night I took it I slept very well and felt great, but the second time it made no difference and I lost confidence in it. It is very expensive for something that is hit and miss.

Hello,
Thank you for taking the time to share your thoughts — we’re really sorry to hear that NIGHT POWDER hasn’t helped your sleep right away, however, many customers do notice the quality of their sleep improves with a bit more time and consistent use. (80% of our consumer trial panelists reported improved sleep quality after 1 week, 89% by week 4, and 91% by week 12.)
We really hope that you experience the benefits of NIGHT POWDER if you decide to stick with it a little while longer, after all it takes time to make a habit! Please keep us posted!
