Best protein powder

I have been using this protein powder for 4 months now and I absolutely love it. Is clean, the ingredients are clear, it tastes good and it is very versatile in the ways you can use it. I prefer it mixed with yoghurt but I have tried it in high protein banana bread and it comes up great so you just need to explore the possibilities. I have never felt bloated or any other weird stuff that happens with other protein powder. I will keep ordering forever! Thank you Onyst

Really great protein powder

Really great protein powder. I bought both the natural flavour and the cacoa flavour. The natural one makes really amazing protein pancakes and the cocoa one I use for smoothies. I tried the cacao one with just water and it wasn’t for me, but mixed with banana and almond milk (or any milk) it tastes great. I even throw in frozen berries and spinach to make it a wholesome delicious smoothie. I love that they are not sweet as I do not have a sweet tooth and also have a great dislike to any artificial sweetener even the natural stevia kind. These are spot on! Won’t buy anything else now.

Delish!

Worth every penny! Finally something that isn’t sickly sweet. Onyst tastes clean and natural and blends beautifully. Proper whole‑food protein without the cloying sweetness. The chocolate is rich and satisfying. I can’t wait to try the peanut butter flavour next.

Clean product great taste

After lots of thought about protein powders I decided to give the cocoa onyst a try after much deliberation. I wanted something as clean as possible, without flavourings, artificial sweeteners, bulking agents and I am so pleased I did. The best I've tasted, can't taste anything beefy or eggy just cocoa as it should be.

I discovered Onyst on social media

I discovered Onyst on social media, decided to look into the product. It looked good, ticked the boxes for what I was looking for, as a clean healthy protein. I ordered and began enjoying it two days later and I am happy that I got exactly what I ordered. Clean, delicious and delivered promptly and packaged professionally. Thank you Onyst Team. I am now a loyal customer and supporter.

ONYSTly and seriously impressed!

Having enjoyed my first bag of cacao protein powder, I have just ordered a second bag of this wonderful product and taken out a subscription. Onyst has produced a product which tastes lovely and rich and blends well in a protein shake. Furthermore, it has the same protein content as many of its competitors although at a much cheaper price. It can’t be an easy balance to strike between quality and price but somehow they have managed it. A personal thank you for taking out a subscription from the founder, Jay, was an unexpected personal touch. So, as long as the quality continues in this way and the price stays within my budget, I look forward to receiving my monthly bag of this delicious and nutritious product. Well done to all at Onyst. I wish you all the best.

Best protein powder I've used to date

Best protein powder I've used to date. Most whey powders give me bad skin but this is all natural, and you can tell. Works great in overnight oats and the vanilla tastes great with raspberries and almond butter 🤤

Quick service provided, very clean tasting whole protein, I’ve used whey but kept getting bother with my skin and vegan protein I found was full of rapeseed and soy etc. This protein is the perfect choice for someone looking for a healthy source of protein.

Onyst protein for an honest lifestyle

A great benefit and supplement to my every day diet knowing i feed my body with the very best i can give it to stay fit and healthy .

Onyst protein powder - 10/10

I recently bought the chocolate flavoured protein powder after having tried 10+ other companies products.

I have been blown away by it. The taste is fantastic and it is incredibly easy on the digestive system.

I am an ultra-marathon runner in my 50's and as sch find it hard to put on muscle. Since I have started using Onyst, I am seeing progress that I have never seen before. I cannot recommend this protein powder highly enough.

Highly recommend

I purchased all three flavours from Onyst Proteins and I’m honestly impressed. Every flavour is really smooth and delicious, with no gritty texture at all. What I love most is the clean ingredients — no artificial sweeteners and no unpleasant aftertaste, which makes such a difference. It’s refreshing to finally find a protein that tastes great and feels good to drink. High quality, clean, and genuinely enjoyable. Highly recommend!

I purchased the vanilla flavour as I’ve been focusing on a whole food diet and I’ve been wanting to limit artificial sweeteners- so far I’ve been quite impressed!

I’ve experienced zero bloating after consumption and the flavour I chose makes a great base to mix with banana and cacao (my fav) and it can be used as a pancake mix.

The customer service has also been amazing. My Black Friday code didn’t process, and they refunded me the difference and were friendly to communicate with.

I’m looking forward to trying additional flavours and supporting this small business :)
