During exercise, increased pH can cause fatigue and hamper performance. Resistance training relies on the anaerobic energy system. This system causes increased pH levels after extended training. Beta-alanine increases muscle carnosine content and improves performance in certain activities.
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 known as the slow protein, and for good reason. In the introductory article to the casein protein series, we discussed how casein protein consumption causes amino acid levels in the blood to increase for seven hours; more than double the time of whey protein. This would make casein a great choice for a night time meal, but, what does the research say about casein's post-workout potential?
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?
Soy protein doesn't have a great reputation in the performance world. Unfortunately, there is not a great deal of research specifically looking at soy protein to enhance recovery. However, there is some to suggest the isoflavones and saponins found in soy protein have anti-inflammatory and anti-oxidative properties, giving it great potential to enhance recovery.
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.
