The document notes that it can be added as an ingredient in:. The whey in these products can be in forms known as demineralized whey, sweet whey, acid whey or reduced forms. Reduced forms and demineralized serum are the forms used in sports supplements.
Ricotta cheese is an important source of whey protein. This high-moisture, unpressed cheese can contain quite a bit of whey, depending on whether it's made from whey alone or a mixture of whey and milk. Sometimes ricotta is made only from milk. Although there are cheeses they contain some Whey protein. For example, the liquid you see floating over the cottage cheese when you remove the lid is whey protein.
Even hard cheese contains a little of this substance. About 20 percent of the protein in cow's milk comes from whey. Compared to whey protein, cow's milk appears to be equally effective in stimulating muscle growth when taken after training. A study in an October issue of Nutrients showed that ingesting 20 grams of whey protein and milk protein triggered muscle protein synthesis in middle-aged men after a workout.
The effects were remarkably the same. The researchers were surprised with the results because whey protein purportedly has a faster digestion rate and increased availability of leucine. Leucine is a particularly important amino acid for muscle stimulation and growth. However, research published in Nutrients just a year later, in June , found that Whey's protein ingestion induced the fastest onset of muscle protein synthesis.
They found that milk protein had an intermediate effect, and casein was shown to have the slowest effect. All three were superior to soy protein when used after exercise. Among all the whey protein sources available for you to choose from, yogurt is one of the best. Eating a variety of protein foods provides you with all of the EAA, plus essential nutrients such as vitamins and minerals that are important for performance and recovery.

If food sources of protein are not available, whey protein products can help you meet your overall protein needs, but there are no official whey protein recommendations.

When high-quality protein foods are not available or not practical, protein products that contain both whey and casein are acceptable and can be beneficial.

This includes lowering blood pressure, blood sugar and reducing symptoms of stress and depression 39 , 40 , 41 , It also protects against cancer, reduces symptoms of hepatitis, increases bone mineral density, improves immune function in HIV patients and increases the lifespan of mice 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , The fact that whey protein is very high in the amino acid cysteine seems to mediate many of these health benefits.
Whey is high in essential amino acids and other healthy nutrients. A commonly recommended dosage is 1—2 scoops around 25—50 grams per day, usually after workouts. Keep in mind that if your protein intake is already high, adding whey protein on top of your current intake may be completely unnecessary.
Concerns about protein causing kidney damage and contributing to osteoporosis are unwarranted. In fact, protein has been shown to protect against osteoporosis, while having no impact on healthy kidneys 56 , 57 , 58 , However, people with current kidney or liver issues may want to avoid whey protein or at least consult with a medical professional before taking it.
