Onyst Reviews 

I received my first purchase about an hour ago and true to form couldn’t wait to try it. So one ‘natural with a hint of vanilla flavour’ shake later I can say I’m very very pleased. It feels like you’re drinking health! I wasn’t sure when I smelled the contents of the pack at first but the taste is mild, not a hint of beef or eggs in my opinion, and although I had a couple of small bits of grittiness they were from the vanilla seeds which is totally forgivable. I am lactose intolerant and have been using milk based protein isolate to get my protein in for training and they are really sweet and I never feel ‘good’ and i can tell immediately Onyst won’t make me feel lethargic. Easy to drink and I can’t wait to use this in my boring breakfasts! I’m a bit sick of only eggs. I’m also a type 1 diabetic so this suits me perfectly as it will hardly raise blood sugar at just 5g carbs per serving. The milk based proteins even if they show no carbs on the label still raise my blood sugar due to the lactose which is basically sugar even in the protein isolate versions. I know this is way more expensive than I would normally pay for a supplement but if I feel good on it it doesn’t matter. I think I’ll recoup the cost eventually if I think about the amount of powders I’ve thrown out over the years due to them being sickly sweet and gritty and tasting just plain bad.
Well done! I love the company ethos fighting the big pharma and fitness industry. I also only buy pure supplements from another company based in Northern Ireland as they have the same mindset. We are slowly being poisoned by all the crap we are being sold under the guise of healthy. I’d eventually love to see more flavours, maybe one with freeze fried raspberries or something. I wish you all the success and you have a loyal customer in me! Good luck! I’ll come back with another review once I’ve been using for a couple of months

Very good advertisement on Instagram;

Very smooth ordering process;

Very convenient delivery of product;

PERFECT PRODUCT 🙏

Great product, I can’t have dairy so difficult to find a good protein source for my drinks, I’ve used other beef isolate but they have allot of other chemicals, ingredients in there then I came across Oynst! Mixed with my banana, almond milk, few ice cubes I just love it and it’s like another meal for me. Highly recommended

After purchasing this for a couple of months, I would really struggle to go back to the super sweet synthetic alternative.

Great product!

Lovely wholefood protein powder, simple and wholesome. Doesn't taste sweet and fake like most others, so don't expect something like that. It tastes real, so it's enjoyable for that reason. Love the whole ethos, I've doubled my subscription.

I have tried so many protein powders but without a shadow of doubt this is the best l’ve tasted, it’s so clean and it’s not sweet like many of the other brands l’ve sampled. It makes wonderful protein shakes and is delicious in Greek yogurt. I purchased the Cacao but will definitely be trying the peanut butter and vanilla…love it.

I have tried many different protein powders over the last few years in the search for one that could help me hit my protein targets but I also wanted one that didn't have lots of unnecessary ingredients and full of stuff that you couldn't pronounce. I also wanted to try it long enough to give an accurate review so this is after 9 months of using it.
Onyst is that product! It mixes really well and tastes great. I like that it is not overly sweet like many others. I mix it into porridge and with milk for my shakes. I'll also sometimes mix a shot of coffee in with it too.
Yes, it may cost more than some of the others on the market but I am happy to pay that for a product that hasn't got loads of cheap fillers and emulsifiers in it that are being proven more and more damaging for your gut and microbiome. Just 6 ingredients is all you need!
I have my Onyst on subscription to keep the costs down a little too and I'm very happy with the product and all the benefits it brings.

An outstanding brand, with amazing ethics. I want a clean protein powder without stevia and this has delivered! My personal favourites are vanilla followed closely by peanut butter. It’s also a huge bag nearly 1kg, each serving is 20g protein so this helps me reach my protein target. Thank you

The quick delivery and the taste do it for me. But more than that is the 6 natural products in this protein. Ive subssubscribed to monthly delivery of the protein as its cheaper and I know ill be using it so its a no brainer. As long as the company continue to only put natural foods in this protein, Ill continue to use it! The peanut butter one is quality.

Order arrived quickly and product is fabulous
You can tell it’s clean and does not contain any nasties.
It mixes well and tastes great.

This is by far the cleanest protein powder in the UK.
I’m speaking about the ingredients, the taste and most of all the gut experience after having the protein shake.
I am a gym regular and my protein intake is one of my priorities in my life. I have been literally through all the protein powders in the US and in the UK market.

ONYST is simply HONEST.

These proteins work for me

At last a protein powder without any nasty added ingredients or sweetners which actually tastes good.
Being lactose intolerant it's hard to find protein powder that is tolerable but Onyst is so versatile.
I've added to stews, shepherd's pie and my daily coffee.
My go to from now on.

Great product and refreshing to see only using few and nature ingredients

Great product and great taste considering it’s only got 6 ingredients, it’s really helping me on my nutrition journey, I’m hitting my protein targets and feeling great with no bloating

I rarely leave reviews, but I’m super impressed! Firstly, very fast delivery. Secondly…this is a cut above all the other protein powders I’ve tried. Usually they are WAY too sweet and synthetic tasting. I ordered all 3 flavours. So far I have only tried the cacao and it’s FANTASTIC. Tastes how it should…chocolatey but not sweet. Absolutely amazing. Mixed it with plain Greek yogurt and kefir, it turned into a smooth chocolatey desert! I LOVE IT! This isn’t cheap but you get what you pay for. I’ll be cutting out other supplements so I can afford to keep subscribing to Onyst -UPDATE- top tip! I reached out to customer service because I found it was clumpy in my shaker. Was recommended by Sofia to get a little rechargeable milk frother. Absolute game changer! Quickly whizzes up to make a fabulous smooth shake!

As a food scientist and recipe developer, I am very fussy about what I put in my body, as I know all the tricks about making a recipe cheaper and flavoursome using crap, essentially.
After lots of research I found ONYST, the cleanest recipe for a protein powder ever. No bulking agents, no additives (E numbers), no gut microbiome altering sweeteners , no artificial flavours. I've fallen in love with the chocolate one. It tastes like 90% dark chocolate, so maybe not for everyone, but you add milk and any sweetness you might want and sorted!. I personally love the fact that it is not sweet.
I feel so good knowing that there are only good ingredients there, that I am using the powder everyday for myself and my children (Mocha coffee for my teenagers in the morning, chocolate milkshake for the little ones). Thanks Jay for being such a purist and developing only with the best and necessary ingredients, you definitely have lots of respect for us, your customers.

Onyst cacao is very tasty, and I don't have digestive issues with it which is a big win as I haven't been able to have protein powders for a few years.

I was an avid drinker of Huel for years before I worked with nutritional therapists and hormone specialists and found out it had been terrible on my digestive system and hormones for a long time. Those powders really mess things up and create early peri-menopause symptoms.

I've now had Onyst every other day for 5 weeks and it's clean and calm on my digestive system and tastes good. I usually have it with milk, peanut butter, banana and sea salt as a smoothie and it's pretty much a meal replacement that way. Love the ingredients list too, can't believe what's in it!

I think the supplement quality and taste is incredible and yes it’s a bit more expensive but I don’t get the usual bloating.

I do want to flag to the owner Jay that I have suffered from IBS for years and because the protein supplement is so high in protein concentrate I have found it makes passing motions a bit harder so some addition of fiber or guidance based on research for balancing the supplement with adequate water content would be helpful. I am early taking this on so cycling and experimenting to see what works for my body.

I’ve been using Onyst for a few months now, and I honestly can’t say enough good things about it! I was so tired of the artificial flavours and overpowering sweeteners used in most commercial brands.
This is completely different, it tastes natural, not overly sweet, but just enough to make a really enjoyable shake.
I’ve tried the Chocolate and Peanut flavours so far, and both are genuinely delicious. I mainly have it in the morning mixed just with water, and if it tastes this good with only water, imagine how good it is in porridge!
It’s honestly been a bit of a game changer for me 😊
