Whey protein is a popular supplement for people looking to increase their protein intake, build muscle, or lose weight. It is a mixture of proteins in whey, a byproduct of cheese production. Whey protein is typically sold as a flavoured powder that can be added to shakes, smoothies, meal replacements, and protein bars. It is generally well-tolerated and has a low lactose content, but may not be suitable for everyone, especially at high doses over long periods of time. Research suggests that whey protein may offer several health benefits, including improved cardiovascular health, reduced risk of metabolic syndrome, and potential anticancer properties. The best time to consume whey protein depends on individual goals and activity levels. For muscle gain and intensive workouts, a single dose of around 0.4 grams per kilogram of body weight is recommended, preferably after a workout to aid in muscle recovery and growth. For weight loss, whey protein can be used as a meal replacement. However, it is important to consult with a healthcare professional before incorporating whey protein into your diet, especially if you have any health concerns or are taking medications.

Whey protein is a convenient way to add protein to your diet
Whey protein is a popular protein supplement for people trying to gain muscle. It has a high leucine content, an amino acid that helps build and repair muscle. Research suggests that whey protein, when used alongside resistance training, can help people build the maximum amount of muscle when they exercise. A 2019 study found that a single serving of around 0.24 grams per kilogram (g/kg) of body weight is sufficient to maximise muscle protein synthesis at rest. For intensive workouts, a single dose of 0.4 g/kg or more is recommended.
Whey protein may also have other health benefits. It may help lower triglycerides, improve cardiovascular health, and have anticancer properties. A 2025 review and meta-analysis found that whey protein supplements reduced triglyceride levels while increasing high-density lipoprotein (HDL) or "good" cholesterol. Additionally, whey protein is low in lactose content and is generally well-tolerated, although people with lactose intolerance should exercise caution.
However, it is important to note that unless your diet is already lacking in protein, supplementing with whey protein may not have a significant effect. If you are already consuming adequate amounts of protein from meat, fish, eggs, and dairy, the benefits of adding whey protein may be minimal. Furthermore, while most health experts agree that the minimum daily requirement of 0.8 g/kg of protein per day is not enough for those building muscle or engaging in athletics, combining whey protein with other proteins, creatine, and carbohydrates may offer additional benefits for individuals doing resistance training.

Whey protein may help lower triglycerides and improve cardiovascular health
Whey protein is a convenient and healthy way to add more protein to your diet. It is a quality protein source that is efficiently absorbed and utilised by the human body. This is especially important for athletes, bodybuilders, or individuals aiming to gain muscle mass and strength while reducing body fat.
Protein is an essential macronutrient for optimal health, and whey protein has been found to offer numerous benefits in this regard. Research suggests that whey protein supplementation may play a crucial role in preventing and managing age-related muscle loss, known as sarcopenia. It may aid in building muscle mass and improving strength, particularly when combined with resistance training.
Whey protein has also been linked to improved cardiovascular health. Studies have shown that whey protein supplementation can help reduce triglyceride levels, especially in healthy adults. Triglycerides are fats that circulate in the blood, and elevated levels can increase the risk of various health conditions. By lowering triglycerides, whey protein may help mitigate these risks.
Additionally, whey protein has been found to increase high-density lipoprotein (HDL), also known as "good" cholesterol. Higher levels of HDL cholesterol can be beneficial for cardiovascular health. A 2024 review also suggested that whey protein supplementation may boost natural antioxidant defences, further contributing to its potential cardiovascular benefits.
While whey protein offers these promising health benefits, it is important to note that it may not be suitable for everyone. High doses over extended periods could potentially lead to certain risks. Consulting with a healthcare professional or a dietitian is advisable to determine if whey protein supplementation aligns with your health and fitness goals.

It can be used before and after bariatric surgery for weight management
Whey protein is a convenient way to add protein to your diet. It is a quality protein source that is efficiently absorbed and utilised by the human body. This is particularly important for individuals looking to lose weight or gain muscle mass and strength.
Whey protein can be beneficial for individuals considering or preparing for bariatric surgery as part of a weight management program. Before surgery, whey protein supplements can be used as meal replacements to aid in weight loss and management. This is because whey protein is low in lactose content and is a popular, well-tolerated, and delicious way to add protein to one's diet.
After bariatric surgery, it is crucial to consume adequate protein as the body's ability to absorb protein is reduced, and protein is essential for healing and maintaining muscle mass during weight loss. Due to the restricted food volume after surgery, it can be challenging to meet the required protein intake, and whey protein supplements can help achieve this, especially in the first six months. Whey protein isolate is recommended for post-bariatric surgery patients as it is a higher-quality, complete protein with minimal calories from carbohydrates and fat. It is a preferred choice as it is "isolated" from the fat and lactose naturally found in milk, ensuring most calories come from protein.
Whey protein supplements, such as shakes, can be a nutrient-dense, convenient, and inexpensive way to meet daily protein requirements before and after bariatric surgery. These supplements are typically discussed and recommended by bariatric dietitians, who can provide guidance on the appropriate parameters for calories and macronutrients in a quality protein shake.
