Post-workout supplements are aimed at improving recovery after working out, and can provide benefits such as improved muscle gains, reduced soreness and recovery time, and restored electrolytes and fluids. On this page, we’re going to cover the science and benefits behind some of the most widely used post-workout supplements. Supplements designated Editor’s Choice are our top choices.
Beta alanine is a non-essential amino acid produced inside the human body and also present in protein-rich foods such as chicken and soybeans.
As a precursor to carnosine, beta alanine increases the concentration of carnosine in muscles. Carnosine, in turn, helps prevent muscle fatigue by buffering out acidic compounds generated during exercise. In many ways, beta alanine supplementation is similar to creatine, since it is not affected by timing and requires daily ingestion to reach maximum effect.
Branched Chain Amino Acids (BCAA)
The branched chain amino acids, or BCAAs, consist of three essential amino acids: leucine, isoleucine, and valine. Each is absolutely necessary for fundamental processes in the body, including muscle development, and needs to be consumed via food or supplements.
BCAA’s specifically facilitate post-workout muscle health by:
- Reducing muscle protein breakdown (MPB)
- Increasing muscle protein synthesis (MPS)
What this ultimately does is increase the net growth of muscle in conjunction with weight training.
Most commonly referred to as CBD, cannabidiol is one of the primary bioactive compounds in the cannabis plant. Unlike other cannabinoids present in marijuana, CBD is not psychoactive, meaning it does not produce any intoxicating effects.
The use of CBD as a post-workout supplement is rapidly growing, particularly in physically demanding sports such as MMA. CBD can provide several recovery benefits, namely:
- Decreasing pain by blocking the pain receptor, GPR55
- Reducing inflammation by triggering anti-inflammatory neurotransmitters, such as anandamide and adenosine
- Improving sleep through reducing anxiety
Coconut water is a sweet, transparent liquid sapped from immature coconuts that is a popular chilled beverage in many tropical countries. Its high electrolyte content enables it to help maintain fluid balance in the body by replenishing lost stores of sodium, potassium, calcium, and other ions during exercise.
Sodium and potassium are especially pivotal for proper hydration, sustaining blood pressure and volume, stabilizing membrane potential, and reducing cramps. Another great benefit is that coconut water has a low amount of calories and sugar compared to other artificially sweetened sports drinks.
Creatine – Editor’s Choice
A naturally-occurring compound widely present in skeletal muscle, creatine is probably the most popular sports supplement available today. While the chief function of creatine is to help sustain adequate energy (ATP) in muscle, it is also considered a solid post-workout supplement because it indirectly enhances muscle growth through higher workout intensity.
Another plus is that creatine might be capable of reducing muscle damage caused by exercise. All in all, creatine has consistently been shown to boost muscle mass and strength when taken regularly, regardless of the timing of supplementation.
Dextrose, or D-glucose, is the only naturally-occurring form of glucose, and is the principal source of energy for all of the body’s needs. It is consumed in the form of carbohydrate foods, and then either converted into fuel for the body or stored in muscles in the form of glycogen.
Having larger stores of glycogen results in an increased exercise capacity for muscles, which should theoretically enable athletes to work out for longer stretches of time. Dextrose seems to be particular useful for endurance athletes, since extensive aerobic exercise rapidly depletes glycogen.
Glycine is a nonessential amino acid that is primarily used to form proteins. Similar to other protein-forming amino acids, glycine has a hand in the maintenance of muscle tissue, especially when combined with resistance training. Early research suggests it may boost the muscle-building activity of leucine as well.
L-glutamine is the most abundant amino acid in the human body, with almost 90% of it present in muscle. Its inherently vital nature to muscle protein synthesis suggests that it can enhance post-workout muscle recovery. In addition, because glutamine is involved in immune system function and strenuous exercise can deplete the body’s glutamine levels, supplementation is also believed to support the immune system.
One of the BCAAs, leucine is an essential amino acid that must be consumed from protein-rich dietary sources, such as meat, fish, and nuts. Leucine is hugely popular among bodybuilders because it the only amino acid known to directly stimulate muscle growth via the mammalian target of rapamycin (mTOR) signaling pathway.
Leucine’s necessity in post-workout supplementation is questionable due to its presence in everyday protein-containing foods. With that in mind, leucine may very well be the key post-workout supplement for those who work out fasted or are on a calorie-restricted diet.
Pomegranate is a fruit-bearing tree from Iran with a long history of use in culinary and ceremonial practices. The juice, seeds, and peel of the pomegranate fruit are loaded with health-boosting bioactive ingredients, especially ellagitannins, which is why many believe it wields medicinal value.
As far as post-workout supplementation, pomegranate has shown potential to improve muscle recovery by reducing soreness and speeding up the time needed for muscle to return to normal strength.
Whey – Editor’s Choice
Whey, a by-product of cheese production, is a solution composed of lactose in water mixed with proteins and minerals. Whey protein is widely considered the best source of protein for building muscle in conjunction with resistance training, and particularly for the time window immediately after a workout.
This is because whey has high concentrations of all essential amino acids for protein building and is very easy to absorb, leading to the highest acute (within a 3-hour period) increase in muscle protein synthesis among all protein sources.
