If you’ve ever opened a container of yogurt and seen a liquid floating on top, that’s whey. Traditionally, cheesemakers used to discard whey before realizing its commercial value. After being separated during the cheese-making process, whey goes through several stages of processing to become what we know as whey protein—a powder added to shakes, meal replacements, and protein-rich foods to benefit from its properties for bodybuilding. Consuming whey protein is a convenient way to boost your daily protein intake.
Whey protein contains an impressive range of essential amino acids that are quickly absorbed by the body. This makes it effective for increasing strength, building muscle, and supporting significant fat loss. However, whey is more than just a protein.
It’s also rich in nutrients, some of which have powerful biological effects. In fact, whey protein is one of the most studied supplements in the world.
Whey contains ACE inhibitors (lactokinins) that have been shown to benefit blood pressure.
Increasing protein intake is also a well-known strategy for fast weight loss. Consuming whey protein can help reduce appetite, boost metabolism, and aid in fat loss while preserving lean muscle.
Potential Side Effects of Whey Protein
Concerns about whey protein causing kidney damage or osteoporosis are unfounded. In fact, protein helps protect against osteoporosis and has no adverse effects on healthy kidneys. However, people with pre-existing kidney or liver conditions should avoid whey protein or consult their doctor before use. Excessive intake may cause digestive issues such as nausea, bloating, diarrhea, or cramps. Overall, whey protein is considered very safe and most people can use it without problems.
