Prima's newest flavour brings peppermint extract and dark cacao together in what might be the most refreshing clean protein bar on the market. Limited launch stock — try it while it's new.
Try Mint Chip →Every bar: 21g protein, 240–250 calories, 10 real ingredients. $3.99 per bar. Zero seed oils.
No ultra-processed isolates. No seed oils. No artificial or "natural" flavors. Just ancestral ingredients your body recognises.
Most protein bars are ultra-processed products masquerading as health food. They rely on seed oils for fat, whey protein isolate stripped of nutrients, synthetic sweeteners, and a long list of "natural flavors" that aren't natural at all. Prima was built to reject all of that.
The brand name — Prima — means "first, before." It's a nod to ancestral nutrition: eating the way humans did before industrial food processing changed everything. Every bar contains exactly 10 ingredients you can pronounce, sourced from quality-first suppliers. Grass-fed throughout. Organic where it matters. Zero seed oils. No exceptions.
Whey concentrate + bovine collagen = full amino acid spectrum from clean sources.
No canola, sunflower, soybean, or corn oil. Grass-fed tallow instead — always.
Organic raw honey — no maltitol, erythritol, sucralose, or stevia blends.
Certified non-GMO and gluten-free across all flavors. No hidden fillers.
Pro Tip: Not sure which flavor to start with? Grab the Variety Pack first — it lets you try all five before committing to a full case. Most customers end up with Cookie Dough or Salted Caramel as their daily staple. Order the Variety Pack →

Real feedback from people who switched from conventional bars to Prima.
"I've tried every 'clean' protein bar on the market and Prima is the first one that actually lives up to the label. Cookie Dough is incredible — it tastes like real cookie dough, not a chemical approximation of it. No seed oils, no weird aftertaste. This is the bar I've been waiting for."
"As someone who follows an ancestral diet, finding a protein bar I could eat felt impossible. Then I found Prima. The ingredient list reads like something my grandmother would have stocked — honey, tallow, grass-fed whey. The Salted Caramel is dangerously good. I keep a box in my car now."
"My CrossFit gym switched to Prima for post-WOD recovery and the feedback has been overwhelmingly positive. Athletes notice the difference — no bloating, no artificial taste, and actual satiety. The collagen plus whey combination makes sense physiologically. We're not going back to the old bars."
Prima has accomplished something rare in the supplement industry: a protein bar that actually deserves to be called real food. The commitment to zero seed oils, grass-fed sourcing throughout, organic honey as the only sweetener, and a 10-ingredient cap is genuinely impressive. The flavors don't just taste clean — they taste good. Cookie Dough and Salted Caramel are legitimately delicious, and the new Mint Chip adds an exciting fresh option. At $3.99 per bar with 21g protein from quality sources, Prima delivers exceptional value for health-conscious consumers who refuse to compromise. We recommend starting with the Variety Pack and then stocking up on your favourite.
