What our customers say about ONYX NUTRITION.

  • First of all I must appreciate the fact that you are the only company that has thought about vegetarians and came up with a plant based protein solution. As a vegetarian, I have faced lots of problems when finding a good source of protein and many nutritionists ended up disappointing me and some scolded me saying that I will have no option but to eat meat for protein. This product is a wonderful invention and a relief for vegetarians. Thank you so much for that. Also, if you can change the taste of it more appealing, that would be great.

  • Thank you so much ONYX...!❤️ Got my package within 2 days... ! Super fast delivery...👍👍 I just want to say a big thank you for providing such a healthy and delicious breakfast. I used to eat buns, breads, and other unhealthy short-eats for breakfast, and for a long time I was searching for a quick, high-protein option. I never liked the raw oats from the supermarket, so this has been the perfect solution for me. The combination of high-protein oats, fruits, and chocolate tastes amazing and keeps me full and energized. Really appreciate the quality this is a great product..!

  • I recently tried Onyx Nutrition, and I’m seriously impressed! It’s proudly the first Sri Lankan-made plant-based protein, and the quality truly stands out. The texture is super smooth, and the taste is much better than most whey powders I’ve had before, no chalky aftertaste at all.
