What types of protein powders are there?

Whey and casein are two of the most popular supplemental sources of protein. Both casein and whey are by-products of cheese production.

Whey protein is the more popular option due to its superior amino acid content, fast rate of digestion, and pleasantness. It releases the amino acids relatively quickly into the system, ready to be used by muscle for restoration and growth.

Casein on the other hand is a slow releasing protein, meaning that it takes longer to digest and releases the amino acids over a longer period of time compared to whey. Casein is more of a specialty protein for those needing slow-release protein.

What is in Whey Protein?

Essential Amino Acids:are the building blocks of protein. Protein from animal sources such as, meat, poultry, fish, eggs, and dairy products are complete protein sources because it supplies all these essential amino acids which you if you want to build and maintain muscle, repair tissues, or make neurotransmitters and hormones. Whey protein contains all 9 essential amino acids making it a complete protein source.

Non-essential amino acids: are the ones your body can generate on its own. You don’t technically need these as much as the essential amino acids, but supplementation is still necessary for plenty of people.

BCAAs:branched chain amino acids (BCAAs) leucine, isoleucine, and valine, which you’ll never find in plant protein. BCAAs are the big gun amino acids that are well-documented for muscle gains and recovery.

Other Proteins: Whey is also rich in the proteins lactoferrin, beta-lactoglobulin, alpha-lactalbumin, and immunoglobulins, which all are antibacterial, antiviral, and antifungal and can help reduce inflammation and improve immune function.

What are the different types of Whey Protein?

There are three main types of whey protein powder, Whey Protein Isolate (WPI), Whey Protein Concentrate (WPC) and Whey Protein Hydrolysate (WPH). Each of these protein powders have unique attributes that may vary in importance depending on an individual’s training regime and body type.

The key difference between WPC, WPI and WPH is refinement, as all begin in the same place, as whey liquid. WPC is usually manufactured via ultrafiltration process. This technique leaves most of the protein fractions in whey intact. Most WPC products contain 70-80% protein and, contain a small amount of carbs and fats.

WPI is processed even further than the concentrate through longer filtering or ion-exchange, removing lactose and any other elements of the concentrate to give a purer protein of around 90% protein content. Due to its lower carb and fat content, WPI is a slightly faster-digesting protein than WPC.

WPH is produced when WPC or WPI is taken through the extra step of hydrolysis to break the amino acid bonds. They are pre-treated with special enzymes that transform the long molecule chains into simpler smaller molecules that get to work quickly, however, it often has a bitter taste requiring many other ingredients to sweeten and mask its natural flavour. It is also the more expensive of the three

Does it make a difference where my protein is sourced from?

Just like how grass fed, organic, and pasture-raised meats are more nutritious and eco-friendlier, the same goes for whey protein powder. What a cow eats impacts the nutritional content of its milk and meat.

Grass fed cows are free to graze the fields and eat naturally grown grass. These animals are raised on organic pastures and fed natural, plant-based diets. Most grass-fed cow farms do NOT use antibiotics, steroids, or pesticides, which have been found to pass down damaging effects to humans with the consumption of cow by-products.

Commercially raised cows are fed grains for most of their life in order to quickly and unnaturally fatten them up. In addition to the unsanitary and inhumane conditions of these types of animal feedlots, it also produces meat and milk that have a different fatty acid profile, not to mention certain micronutrient differences.

The main nutritional difference is that grass fed whey contains more omega 3 fatty acids that are vital to proper cognition and mood, as well as decreased risk of heart disease and known for being anti-inflammatory. While grain-fed whey is generally higher in omega 6’s. A diet excessively high in omega 6 fatty acids (as is the case in a typical American diet) has been linked with a myriad of chronic and degenerative diseases rampant in today’s society.

Grass whey are also higher in conjugated linoleic acid (CLA), which is a type of omega 6 fatty acid that is showing increased promise in fighting cancer and aiding in weight management.

Grass fed whey not only increases the nutritional value of the protein powder but also reduces the ecological footprint your protein powder leaves on the earth.

When should I drink my protein?

This really depends on your health and fitness goals. So, depending on whether you want to lose weight, build muscle or preserve muscle, you may need to consume it at a particular time of day.

For losing weight, consuming protein-rich snacks between meals is better. It can help curb hunger, which could lead you to eat fewer calories throughout the day.

To build muscle, in the 15-30 minutes post workout the body needs protein in order to kick-start the recovery process.

To help prevent muscle loss, aim to eat 25–30 grams of protein per to help spread your intake over the day.

Endurance athletes may see improved performance and recovery from taking protein with a source of carbs during and after exercise. Resistance-training athletes can benefit from taking protein either immediately before or after a workout.
