    • 🌟 Best Whey Protein I’ve Ever Tried! 🌟
Flavor Name: Chocolate Size: 1.99 Pound (Pack of 1)
This is by far the best whey protein I’ve ever had. The chocolate flavor is delicious — rich and smooth without being too sweet. I take it every morning for breakfast, and it keeps me feeling full and satisfied until lunchtime. The quality is excellent, just like all Thorne products. I truly trust this brand — they stand behind their formulas and always deliver top-tier supplements. I 100% recommend it. If you're looking for a high-quality, great-tasting protein with proven reliability, this is the one! ... show more

    • Tastes good and mixes well.
Flavor Name: Vanilla Size: 1.84 Pound (Pack of 1)
Unlike most whey protein supplements, Thorne whey protein isolate tastes good and mixes well with water. I recommend this product for improving your daily protein intake.

    • Definitely sweet but good mixed
Flavor Name: Vanilla Size: 1.84 Pound (Pack of 1)
The vanilla would be too sweet on it's own for me but with strawberries and spinach it's perfect.

    • Expensive. Taste good. Sadly toxic!!
Flavor Name: Vanilla Size: 1.84 Pound (Pack of 1)
Review Image by Heather.Rox Heather.Rox
My favorite so far. All about gains but need a healthier whey option. I’m sensitive to dairy and other options made me feel bloated. This feels clean. Give me energy, naturally like vitamins health. Definitely pricey so I can’t purchase regularly and obviously they don’t fill it to the top. It’s about a halfway filled so a little disappointing for how much spent with how long it last but will purchase again when I able to splurge. Recommended to all my training clients too. Update from my previous review : now may 2025… So I’ve been using this product for a while. And I loved it. I did start noticing some changes in regards to the quantity of the product you’re purchasing. We can’t lie. It’s a hefty price line for protein powder. I also believe that you have to spend money for quality, especially with whey proteins. The other day, I was looking at some of the labels, and I noticed it had a toxic metal sign that was only advertised in warning to California. And this is because California has strict laws against this so they have to give the warning… but shouldn’t everyone be warned about this. We are being poisoned with toxic metals every day. The last thing I want is it to be in my smoothies that I think I’m making very consciously and healthy at home. So I started doing research. And that’s when I noticed that they were bought out by Nestlé in 2021. Why does this matter. Need I say more. I do think it was once a conscious product, but I do think we are sadly following for scams. And one big corporations by Healthy products like this they do change things. So not only am I getting less product but I’m getting. toxic product. And again if you do your research, whey protein is already very, Suspicious .. if you already have hormonal imbalance is. This is not gonna be a good situation for you. Sadly, I recommended this product to several of my personal training clients and now I feel very guilty and obligated. Some of them have health conditions and there’s no way in Chance that heavy metals are gonna help that… take with that what you will. ... show more

    • High-Quality Protein with Clean Ingredients
Flavor Name: Chocolate Size: 1.99 Pound (Pack of 1)
I've been really impressed with Thorne’s Whey Protein Isolate. The taste is smooth and not overly sweet, and it mixes well with just a shaker bottle—no clumps or chalky texture. I especially appreciate the clean ingredient list and the fact that it’s NSF Certified for Sport, which gives me confidence in its quality and purity. It also sits well with my stomach, likely due to the added digestive enzymes. The only reason I’m giving it 4 instead of 5 stars is the price—it's definitely on the higher end per serving, and I wish there were more flavor options or a larger tub size for better value. Still, if you're looking for a reliable, clean protein powder, this is one of the best I've tried. ... show more

    • I didn’t know I could truly love a protein powder…
Flavor Name: Vanilla Size: 1.84 Pound (Pack of 1)
The flavor and consistency are unmatched and it was actually easy to digest which is something I’ve never experienced, and is crazy for me bc I have serious issues with whey causing bloating and had actually given up on it completely. 100/10 would recommend JUST bc it’s delicious, the fact that it’s such high quality at a reasonable price is just the cherry on top. I ordered the vanilla to try first and just mixed with cold water using a frother/whisk thing just to get a gauge of taste and consistency and I would actually drink it that way, which I never ever imagined doing with protein lol- later I added it to a smoothie and it was also delicious, almost could not taste it over blueberries but the subtle and delicious vanilla flavor was there. ... show more
