Starting your fitness journey and wondering which protein supplements should you incorporate to get the best results? There are so many types of protein – whey protein, casein protein, and plant protein that you might get confused in choosing one. It is best to seek medical help and rely on the expertise of your trainer. 

Whey protein 

Whey protein is a high-quality protein derived from milk during the cheese-making process. It’s one of the two main proteins found in milk, the other being casein. When milk is curdled and separated into solids (curds) and liquid (whey), whey protein is obtained from the liquid portion. Whey protein is considered a complete protein because it contains all nine essential amino acids that the human body cannot produce on its own and must obtain through the diet.

There are three main types of whey protein – 

  • Whey Protein Concentrate (WPC): This form contains varying levels of protein (typically around 70-80%) along with some fats and carbohydrates. It retains more of the beneficial nutrients found in whey.
  • Whey Protein Isolate (WPI): whey protein isolate undergoes further processing to remove more fats and carbohydrates, resulting in higher protein content (often around 90% or more). They are usually lower in lactose as well, making them a better option for individuals with lactose intolerance.
  • Whey Protein Hydrolysate (WPH): This form has been pre-digested, meaning it’s partially broken down into smaller peptides. This can make it easier for the body to absorb and may cause fewer issues for people with lactose intolerance or digestive sensitivities.

Casein protein 

Casein protein is another type of protein found in milk, along with whey protein. It makes up the majority of the protein content in milk, accounting for about 80% of the total protein, while whey protein makes up the remaining 20%. Casein protein is unique in its digestion and absorption characteristics compared to whey protein. There are three main types of casein protein supplements – 

  • Micellar Casein
  • Casein Hydrolysate 
  • Casein Blends

Plant protein 

Plant protein refers to the protein derived from plant-based sources. These sources include a wide variety of plants such as legumes (beans, lentils, peas), grains (quinoa, oats, rice), nuts and seeds (almonds, chia seeds, pumpkin seeds), and certain vegetables (broccoli, spinach). Plant protein is an essential component of a balanced diet, providing the body with the necessary amino acids required for various bodily functions, including muscle building, repair, and overall health.

Unlike animal-based proteins, which tend to be complete proteins containing all the essential amino acids, many plant-based protein sources may lack certain amino acids. But you can combine different plant protein sources to get all the required amino acids. Some of the most common sources of plant protein are – 

  • Legumes like kidney beans, black beans, lentils, chickpeas 
  • Grains like quinoa, brown rice, oats, whole wheat
  • Nuts and seeds like flax seeds, chia seeds, almonds, pumpkin seeds 
  • Soy products like edamame, tofu, and tempeh
