Best BCAA Capsules Guide

Before digging deeper into the best BCAA capsule supplements, we must first understand why they’re valuable to anybody training hard in the gym on a regular basis.

8 Reasons Why BCAA Capsules Are Worth Your Hard-Earned Investment

1. Convenience: Branched-chain amino acids (BCAAs) are essential amino acids your body cannot synthesize. Hence, you must obtain them from whole foods and supplements. In today’s busy world, people live at a frenetic pace – convenience is of utmost importance. Sure, top-notch BCAA supplements in powder form are also convenient. However, BCAA capsules (unless they’re the size of horse pills) take it a notch higher: just pop one or two capsules in your mouth, wash them down with water, and you’re all set. It’s like taking a multivitamin in the morning after a heavy breakfast. It’s as easy as one-two-three.

2. Product purity and ingredient safety: If there’s one glaring downside to supplementing with BCAAs in powder form, it’s the inclusion of fillers. Unfortunately, many bodybuilding manufacturers lace them with artificial food colorings and sweeteners (such as sucralose) in a desperate attempt to please your taste buds. Sometimes, taste is worth sacrificing for your long-term health. In general, BCAA capsules are a safer alternative than their counterparts in powder form. If you prefer the latter, do your due diligence- check out our B5 Supplement Guide to give you the lowdown on buying supplements and make yourself a shrewd consumer.

3. Increased muscle protein synthesis (MPS): If you want to remain in an anabolic state everywhere you go, BCAA capsules are a must. Combining these with strength or anaerobic training trigger the mTORC1 signaling pathway. These, in turn, result in muscle growth in conjunction with sound nutrition and enough sleep.

As hard evidence, the June 7, 2017 issue of Frontiers in Physiology says, “The ingestion of BCAAs alone, without the concurrent ingestion of EAA (essential amino acids), intact protein or other macronutrients, increases the stimulation of mTORC1 activity and myofibrillar-MPS following exercise in resistance-trained young men.”

4. Ramped-up energy levels: BCAA capsules not only help you muscle up, but they also help increase your energy levels. The muscle tissues absorb BCAAs for purposes of energy expenditure. Experts believe the muscles burn BCAAs during hard training (which is why some of them prefer BCAAs as an intra-workout supplement).

“Fatty acids may be one of the regulators of BCAA catabolism and that the BCAA requirement is increased by exercise. Furthermore, BCAA supplementation before and after exercise has beneficial effects for decreasing exercise-induced muscle damage and promoting muscle protein synthesis; this suggests the possibility that BCAAs are a useful supplement in relation to exercise and sports,” per the October 1, 2004 issue of The Journal of Nutrition.

5. Increased fat loss: BCAA capsules aren’t just great for muscling up, but they’re also helpful if you want to lean out. Fitness experts believe individuals who are getting sufficient amounts of branched-chain amino acids maintain an ideal weight and keep obesity at bay. They credit the anabolic amino acid, l-leucine, for this. Aside from its ability to kickstart muscle protein synthesis, it also helps ramp up fat oxidation and energy expenditure.

“Ingestion of a supplement containing BCAAs while following an eight-week resistance training program resulted in a greater decrease in percent body fat, an increase in lean mass, and 10-RM strength gains on the bench press and squat vs. ingestion of a whey supplement or a sports drink,” per the July 31, 2009 issue of the Journal of the International Society of Sports Nutrition (via NCBI.NLM.NIH.gov). It bears repeating: supplementing with BCAAs while on a regular strength training program helps you muscle up and lean out.

6. Fewer instances of delayed onset muscle soreness (DOMS): Nothing could be more frustrating than experiencing delayed onset muscle soreness (DOMS). As the name implies, it is muscular discomfort one experiences a day or two after unfamiliar exercise. If you’re into bodybuilding, you may have experienced DOMS previously. Fortunately, science reveals branched-chain amino acids (BCAAs) can help ward off DOMS.

Twelve healthy and untrained females were the subjects of a study in Nagoya, Japan in June 2010. Researchers divided them into groups which supplemented with BCAAs prior to training and a placebo. Both groups performed squat exercises for several days. They experienced a peak in DOMS on days two and three of the experiment. “However, the study revealed that BCAA supplementation greatly reduced the level of soreness when compared with the placebo. According to this study, BCAAs may be beneficial in regard to reduced soreness when starting a new training program or returning from a period of rest or injury,” per Alexandra Pires-Menard, OSS Intern of McGill University’s Office for Science and Society in Canada.

If you’ve been having DOMS issues, taking BCAA capsules should help you nip these in the bud sooner than later.

7. Increased endurance and greater resistance against fatigue: Sure, taking a pre-workout supplement with tried and tested endurance-enhancing components such as beta-alanine, caffeine, creatine, l-citrulline, and the like can help you bust through your fitness plateaus. However, BCAAs also have a reputation for warding off fatigue.

“It is presumed than an intake of the BCAAs can lower the concentration of serotonin, a central fatigue substance, during endurance exercise, which subsequently can reduce the concentrations of muscle damage substances such as CK and LDH and enhance exercise performance,” per the November 28, 2013 issue of The Journal of Exercise Nutrition & Biochemistry (via NCBI.NLM.NIH.gov).

If you’re going through a slump in your fitness routine, taking BCAA capsules should help you get your second wind. With that, expect to conquer your workouts on a regular basis.

8. Improved muscle preservation: You work hard to earn muscle mass  – you train regularly, pay attention to your nutrition habits, supplement wisely, and get enough sleep. Earning muscle is just half of the long-term fitness equation. You also have to preserve it. BCAA capsules can help you do just that.

“Our data suggest that under hypocaloric conditions, those who participate in heavy resistance training can maintain lean muscle mass and muscular performance by utilizing a BCAA product pre- and post-workout,” per the January 5, 2016 issue of the Journal of the International Society of Sports Nutrition (via NCBI.NLM.NIH.gov). When you follow the said recommendation, we’re confident you’ll preserve hard-earned lean muscle mass.

To achieve the best results, people in this group should look for supplements that provide extra support for:

  • Muscle protein synthesis/muscle mass
  • Energy and endurance
  • Fat loss/thermogenesis
  • Recovery time
BCAA capsules work well in tandem with a top-notch pre-workout supplement. Both of these supplement categories help ramp up energy levels and stave off fatigue. The best pre-workout supplements help increase both physical and mental energy to help you get the most out of your workouts.

What Ingredients Should People Look for in a BCAA Capsule?

BCAA capsules are among the simplest bodybuilding supplements on the market. Let’s rattle off the key BCAA capsule ingredients which give you the best bang for your buck.

L-leucine is the most anabolic amino acid and is a key component of any high-quality BCAA capsule formula.

L-Leucine

L-leucine (or simply leucine) is the most anabolic amino acid which helps kickstart the muscle protein synthesis (MPS) process. It’s also the most abundant BCAA in muscle tissue. Leucine triggers muscle growth by activating a compound in muscle known as mTOR (mammalian Target of Rapamycin).

“Leucine-enriched essential amino acid ingestion, in combination with resistance exercise in some cases, may be a useful intervention to promote mTOR signaling and protein synthesis in an effort to counteract a variety of muscle wasting conditions (e.g. sarcopenia, cachexia, AIDS, inactivity/bed rest, sepsis, kidney failure, and trauma),” per the May 11, 2008 issue of Current Opinion in Clinical Nutrition & Metabolic Care (via NCBI.NLM.NIH.gov). The key takeaway: if you want to remain in an anabolic state, try supplementing with l-leucine. You simply can’t go wrong with it.

Leucine isn’t just about building muscle – it can actually preserve it. In fact, the December 2008 issue of Journal of Medicine and Food (via NCBI.NLM.NIH.gov) says, “Several recent studies provide evidence that leucine aids in the retention of lean mass in a hypocaloric state.”

It doesn’t stop there. Studies also suggest leucine helps boost fat loss. “There is increasing evidence that the BCAAs, and specifically leucine, have unique roles in metabolic regulation beyond the fundamental role of amino acids as substrates for synthesis of proteins,” per the January 1, 2003 issue of The Journal of Nutrition.

Long story short, if you are trying to muscle up and lean out, l-leucine should help you achieve your fitness goals. It’s clearly more than just an anabolic agent. Supplementing with BCAA capsules with key amounts of l-leucine (around two grams per serving or s0) should help you stay on the right track.

L-Isoleucine

The branched-chain amino acid l-isoleucine has several key benefits:

  • Increases exercise endurance
  • Repairs muscle tissue
  • Maintains a positive nitrogen balance
  • Promote healthy blood sugar levels
  • Shortens recovery time
  • Plays a key role in blood clot formation and hemoglobin production

It turns out l-isoleucine also helps ward off carcinogenicity. Japanese researchers made this conclusion after using rat subjects in a study which the American Association for Cancer Research’s official website published in April 2007. We can clearly see this BCAA is a bona fide Jack of all trades. It should help you shore up your long-term health.

L-Valine

Just like l-isoleucine, l-valine is another well-rounded BCAA which should help you bust through your fitness plateaus. Let’s rattle off its important health benefits:

  • Increases endurance
  • Repairs muscle tissue
  • Quells anxiety
  • Improves sleep quality
  • Suppresses appetite
  • Increase muscle growth
  • Enhances cognitive function

“Consuming (a) BCAA drink during (the) exercise recovery period may provide the muscle with an anabolic environment by stimulating insulin secretion and increasing T/C ratio,” per the April 21, 2010 issue of the Chinese Journal of Physiology (via CPS.org.tw). This substantiate’s l-valine’s ability to increase muscle growth. Now you know why it is a crucial part of the BCAA equation.
