Protein powders can support muscle health. And healthy muscles are important for our strength, balance, and bone health. But not all protein powders have the same effects or come from the same source. Whey is one popular option. “Whey protein is made from milk and contains all of the essential amino acids, which can help the body maintain and gain muscle,” said Christiane Matey, MSHS, RDN, LDN, ABAAHP, a registered dietitian based in Mooresville, North Carolina. Research suggests whey protein may support muscle growth and recovery.1 Nutricost Whey Protein Concentrate topped our list of the best protein powders for women. The brand also makes whey protein isolate powders, including a version made from grass-fed milk.
Our older adult testers evaluated Nutricost Whey Protein Concentrate on taste, ease of use, and value. We also reviewed its protein content, ingredients, and third-party testing. Comparing Nutricost’s concentrate to its whey protein isolate or to other brands? Knowing the differences can help you choose what best fits your health and goals.

What are the benefits of Nutricost protein powder?
Nutricost Whey Protein Concentrate provides 25 grams of protein per serving. It has a high protein-to-calorie ratio, with more than 80% of its calories from protein.
“Whey is easily absorbed and rich in leucine, the amino acid most tied to muscle building,” said Melanie Murphy Richter, MS, RDN, a registered dietitian based in Santa Monica, California. Richter is a longevity and metabolic health expert and co-hosts he Almost Forever podcast.
Nutricost also includes calcium, potassium, and sodium, plus a small amount of iron. It is low in carbohydrates, sugar, and fat, with 2 grams of sugar per serving. Nutricost also backs its products with a 60-day money-back guarantee. The brand offers free shipping on orders over $59 and discounts on subscription orders.
What are the potential side effects of Nutricost protein powder?
Nutricost Whey Protein Concentrate contains lactose, a sugar found in milk. People who have trouble digesting lactose may experience unpleasant side effects. “The most common are digestive: bloating, gas, or constipation,” said Richter. “Lactose and sugar alcohols used as sweeteners are frequent culprits.”
Nutricost Whey Protein Concentrate also contains sucralose. Sucralose is an artificial sweetener that some people may prefer to avoid. During our testing, one tester noticed a strong aftertaste. Each serving has 2 grams of sugar, which is relatively low. But formulas may change by flavor. If you’re tracking your sugar or carbohydrate intake, check the nutrition label.
Kidney disease or other health conditions may require limiting or adjusting protein intake. “Anyone with chronic kidney disease should talk to their doctor or dietitian before adding protein powder, since their protein needs may need to be carefully managed,” Richter said. “The same goes for people with liver disease or anyone on a prescribed diet. Hydration matters too, especially as protein intake goes up.”
More protein isn’t right for everyone, and protein powders can affect your overall intake of certain nutrients. “Your body can only use so much protein at once, and relying on [supplemental forms] can crowd out the fiber, healthy fats, and plant compounds you get from whole foods,” Richter said.
Check with your health care provider before adding a protein powder to your routine. This is especially important if you take prescription medicines or other supplements. They can help you decide how much protein you need and whether this powder fits your health needs.

In our survey of 250 older adults, about 61% favored ready-to-drink protein shakes, while roughly 17% chose protein powders.2
How to take Nutricost Whey Protein
One rounded scoop of Nutricost Whey Protein is about 1/3 cup. Mix that amount with six to 10 ounces of water, milk, or another beverage, per the product instructions. You can also blend it into a smoothie with fruit or yogurt for extra nutrients. Our testers found it mixed well without extra shaking. It also stayed blended while drinking. Nutricost offers 12 flavors, so you can try a few to find one you like. We tested the vanilla flavor, which our testers found very sweet. But that flavor may appeal to someone who likes sweet drinks.
Protein powder is meant to supplement your diet, not replace balanced meals, our experts said. Many people can get enough protein from foods like eggs, fish, beans, dairy, and lean meats. Older adults may also benefit from spreading protein across meals and snacks. This may help support muscle health more effectively than eating most of your protein at once.
If you have a health condition or take medicines that affect your diet, talk with your doctor or a registered dietitian first. They can tell you how much protein you need and whether a supplement makes sense for you.
Who should consider Nutricost protein powder?
Nutricost Whey Protein Concentrate may suit older adults who want to increase their protein intake. It may appeal to those who prefer sweeter drinks or don’t mind artificial sweeteners. Whey protein concentrate typically contains more lactose and fat than whey protein isolate. People sensitive to lactose may want to consider other options. But it can be a good choice for those who tolerate dairy well. Nutricost offers 12 flavors and discounts for buying larger containers. So it may also appeal to people who enjoy flavored protein drinks and want to save money over time.
You should consider Nutricost if you:
- Want a protein powder with plenty of protein and few extra calories
- Enjoy flavored protein drinks and wants several options
- Tolerate whey protein and dairy products well
- Prefer to buy in bulk to lower the cost per serving
You may consider other options if you:
- Avoid dairy: Nutricost contains whey protein concentrate, which comes from milk. Consider Transparent Labs Vegan Protein instead. It uses plant-based protein from rice and peas.
- Prefer to avoid artificial sweeteners: Nutricost uses sucralose. Some 1st Phorm Level-1 flavors use monk fruit extract. This may be a better fit if you prefer that type of sweetener.
- Want to try a powder before buying in bulk: Nutricost offers a 60-day return policy. But its best per-serving price comes with the larger container. Legion Whey+ Grass-Fed Whey Protein offers free shipping on first orders and a 365-day return window. This allows for more flexibility when trying a new product.
