## Description

Perfect for making post-workout shakes, smoothies, baked goods, and between-meal snacks, our chocolate whey protein powder helps you meet your protein goals. Formulated with 30g protein, 2g sugar, and 6.9g BCAAs per serving, our chocolate protein powder also makes it easy to absorb bioactive ingredients like lactoferrin, CLA’s, L-­Carnitine and L­-Glutamine. Unlike traditional supplements, our grass-fed whey protein isolate powder is made using only the highest-quality ingredients, nothing artificial. Enjoy better health and performance, without compromising on taste with our whey protein isolate powder.

Review: So to start It’s 100% grass-fed, gluten-free, and free of artificial sweeteners, which aligns perfectly with clean eating goals. The transparency of the third-party testing is a huge plus!! Plus you can easily access the lab results online. The chocolate flavor has a mild, natural taste thanks to organic cacao, but it might seem slightly bitter to some, personally I always add it in a shake with frozen fruit and it tastes bomb to me ! While it mixes well in smoothies or milk, it can clump a little in plain water so just a heads up there. At around $1.50–$1.90 per serving, it’s not the cheapest, especially compared to the unflavored version, but the clean ingredients and high protein content make it worth considering for anyone who values quality over cost.
Review: clean protein that doesnt upset my stomach. but most powders dont so take that with grain of salt. A bit expensive, but good to know ingredients are clean. My wife says she can taste aluminum in it, but i cant. Good for shakes, protein ninja creami. a bit clumpy but the good always are. Prefer this over the fake sugar ones

## Questions & Answers

**Q: Is this undenatured protein?**
A: Hi Kevin, thank you for your question. Yes, our whey isolate is undenatured. We utilize cold processed microfiltration and test post production for nutritional values to ensure proteins and growth factors are undenatured. Please email us if you have any other question. Thanks!

**Q: Why is the lysine amount so small per ~30g serving?  this is much less than competitor whey isolates.  promix=.7g, naked whey=2.3g, natural force=3.1g**
A: The amount of Lysine in promix isolate is 3.0g, not 0.7g.  If you are looking on their website, you're looking at the wrong line.  Methionine is just below it at 0.7g.  Lysine is 3.0g.

**Q: Which cow milk use A1 or A2?**
A: Hello Muhammad, thank you for your question. The majority of our cows are heritage breed Jersey cows with A2 milk but our heard is not 100% A2. Our whey isolate contains no casein protein, including no presence of A1 β-casein. Please email us if you have any other questions. Thanks!

**Q: How much of this protien is not from additives?**
A: Really only the producer could give an adequate answer.
