"Love all the nutrabio products!"
"I love this protein so much! It mixes well and tastes great! My only issue is that it’s not back in stock and hasn’t been for months! Please tell me you are making more! It’s sooo good!"
"This is the best protein powder I have ever taken! I stayed away from whey because I thought it bothered my stomach, but this one is so clean and not full of added junk!! I take this daily and have not had any stomach issues! No bloating no gas nothing! This is also one of the VERY FEW out there on the market that has natural sweeteners, no sucralose!! Do you know how hard it is to find anything without sucralose in the nutrition store or any line aimed at working out or fitness!!??? I am so thankful they have made this product so clean AND it tastes fabulous!!! I add mine to water only and a tbsp of PB fit peanut butter it’s amazing!! I will be a customer on subscription for life with this product!!!"
"Love it !! Wish it came in the 5lbs bucket, and was a bit more cost effective !"
"Super clean, awesome taste, no complaints, great protein."
"Tastes awesome and mixes really well."
"Phenomenal taste!"
"I'm a big proponent of clean & grass-fed whey protein powders. This one is exceptional though expensive for me. The chocolate is great tasting although a bit watery at recommended dosage (8 oz). Therefore, I add a bit of whole milk to counteract that (3 oz milk/5 oz water). However you like it, it does the work feeding muscle and pleasant to drink. I'm hoping NutraBio creates a grass-fed Casein protein for bedtime."
"The first time I ordered this was through Amazon, but I’ve quit them. When I started running low I searched and found the company. I really like adding this product to my morning oatmeal. The taste is very good and it mostly dissolves with little gritty feeling. I will continue ordering this through Nutrabio. com as needed."

It’s rich in essential amino acids, naturally occurring BCAAs, and beneficial whey fractions, while being free from GMOs, hormones, antibiotics, and artificial ingredients.
Grass-fed whey comes from cows that are raised on a natural, grass-based diet, resulting in a cleaner, more nutrient-dense protein with higher levels of omega-3s, CLA, and antioxidants. Traditional whey may come from grain-fed cows and often lacks the same purity and nutritional quality.
