Beta-alanine is a very popular non-essential amino acid found in many pre-workout supplements. It's associated with decreased fatigue and potentially, increased performance in several activities. Let's take a look at some research on this supplement's safety.
Beta-alanine is an amino acid produced in the liver. Beta-alanine has seen a surge in popularity over the last few years. Of all the products contained in the Supplement Database, 36% of them contain beta-alanine, making it the second most popular ingredient behind caffeine.
In our series on soy protein, we covered topics including its effects on testosterone, health benefits, and body composition. Here we'll go over our findings and make a final recommendation on whether or not soy protein is worth taking.
Casein protein has long been known as the "slow" or"nighttime" protein because of its relatively slower travel time compared to other options. While whey protein is digested very quickly and typically used after a workout, casein takes longer to digest. This makes it, at least hypothetically, a great option as a nighttime/pre-sleep snack.
Casein is commonly referred to as the slow or nighttime protein because of its relatively slow digestion time compared to other options. It's perhaps the second most popular protein after the king: whey. If whey protein is the most popular, is casein good for anything?
The Supplement Database launched in early 2019 as a place to find easy to read, unbiased, and research-based supplement ratings and reviews. Since then, it's grown to include ratings on both ingredients and products in multiple categories. At its core, the database uses information from peer-reviewed research articles to rate supplements in an easy to understand format.
All products are rated in seven areas; a product is given a thumbs up/down in each area. Based on these thumbs up and down ratings, products are also given an overall up or down recommendation.
Diets rich in protein increase thermogenesis, spare muscle protein, and improve glycemic control. Consuming protein before or after exercise also increases protein synthesis1. Put together, these benefits have the potential to improve body composition. Let's take a look at whether or not soy protein has a role to play in increasing muscle mass and decreasing body fat.
The process of making whey protein creates three main products: concentrate, isolate, and hydrolysate (or hydrolyzed whey). The main difference between the three is protein content, the protein's amino acid length, and cost. Does this added cost lead to additional benefits?
Whey protein is a byproduct of cheese production. Milk is made up of two proteins: whey and casein. To make cheese, the proteins are separated. The protein powder we take after a workout starts its journey as a thin, watery liquid. This liquid is processed, and eventually turns into the powder we all love. The amount of processing dictates its final form.
