It's the only protein I trust. It's unique in having no additives or sweeteners, just pure protein. Tastes great in milk.

This is the quality protein I've ben looking for. I've tried many, always ending up with an upset gut. I can assure anyone if your looking for a clean protein, this is the one.

The unflavoured and unsweetened protein is my go to daily protein intake , very versatile and clean tasting product

Highly recommend. I use the unflavoured protein and it's great. Mixes well in overnight oats and not grainy at all.

More to my taste than flavoured powders. I add it to my smoothie most mornings.

I'm very fussy about my protein powder. I love this one.

Our plain proteins are unsweetened, unflavoured and completely free from artificial extras.
If you've tried other protein powders you know they often come with a sickly sweet taste or strange texture. Ours do not, thanks to being pure and all-natural.
While both come from milk and are high in protein, the key difference is how your body digests them. Whey protein isolate is fast-digesting—ideal for after exercise when your body needs a quick protein boost. It’s filtered to remove nearly all fat and lactose, making it light and easy on the stomach.
Calcium caseinate, on the other hand, digests slowly. This means it releases amino acids steadily over several hours, making it perfect for between meals or before bed. It’s more filling and sustaining—ideal if you're looking to stay nourished for longer. Think of whey as your post-workout go-to, and casein as your all-day or overnight support.
Yep! Every plain protein at Purition has all 9 essential amino acids + BCAAs
Yes, our Calcium Caseinate is suitable for vegetarians.
Due to its slow-digesting nature, it's ideal to consume before bedtime or between meals to support sustained amino acid delivery.
