Review: My favorite banana protein powder - I’m sad to see this item is no longer available because it has become my favorite protein powder. I love the packaging (I’m not a fan of the large canisters) which makes it easier to retrieve the product as you get closer to the bottom. The quality of the powder is noticeably better than those I’ve tried in the past. I enjoy the flavoring, mixability, and how easy it is to add to almost any breakfast dish or baked good.
Review: Matrix protein - Syntrax Matrix is a great protein mix that consists of three different protein types releasing in different way/time + several important Amino Acids. Use it for many years since it’s really best-tasting protein. Mixes well and easily with milk or milk/water in shaker bottle or blender cup. My absolute favorite is cookies&cream, but this new banana&cream tastes rather good (not too strong, not too artificial, close to banana milk shake taste).

### ⭐⭐⭐⭐⭐ My favorite banana protein powder

### ⭐⭐⭐⭐⭐ Matrix protein

Use it for many years since it’s really best-tasting protein. Mixes well and easily with milk or milk/water in shaker bottle or blender cup.

### ⭐⭐⭐⭐ More “Banana Cake” Than Bananas & Cream
*by H***D on March 25, 2026*

Like other protein powders from Syntrax, the quality is solid. It mixes well, has a smooth texture, and performs as expected from a nutritional standpoint. The main differentiator here is the flavor. Despite the name, it doesn’t really taste like a classic bananas-and-cream profile. Instead, it comes across more like a banana cake -- slightly sweet, with a noticeable “baked” flavor. It’s not bad, but it does lean a bit artificial and may not match what some people expect from the label. For me, it’s good but not a top-tier flavor. I’d use it again if needed, but I’d choose other flavors (like Chocolate Supreme) first if they’re available. Overall, a solid protein powder with dependable performance, but the flavor is more niche than the name suggests.
