BCAA supplements -

BCAAs may help prevent weight gain and enhance weight loss. However, more research is needed to determine whether supplements provide any added benefits over a high protein diet.

One possible complication is hepatic encephalopathy HE , which can lead to confusion, loss of consciousness and coma. A review suggests that in patients with liver disease, BCAA supplements may be more beneficial than other supplements at reducing the severity of HE Another review of studies in patients undergoing liver surgery reported that BCAA-enriched solutions may help improve liver function, reduce the risk of complications, and decrease the duration of hospital stay BCAA supplements may also be effective at reducing fatigue and improving weakness, sleep quality , and muscle cramps in individuals with liver disease In cases of liver cancer, taking BCAA supplements may help reduce water retention and decrease the risk of premature death However, if you have liver disease, please speak with your healthcare team about using BCAA supplements before starting them.

BCAA supplements may be effective at improving liver function and decreasing the risk of complications in individuals who have liver disease. Furthermore, there are no official recommended daily requirements for BCAA though there are studies that have suggested different amounts 44 , However, people who include sufficient protein-rich foods in their diets most likely do not need to take supplements.

Many people who are trying to gain muscle also take them in the morning and before bed. However, whether the exact timing makes a big difference for this has not been studied properly.

There is no official recommended dose for BCAAs, and since a diet that is sufficient in protein-rich foods may be all you need, you should speak with a healthcare professional before supplementing.

Adding foods from the list above to your diet will help you increase the amount of BCAAs you get each day. However, individuals with a rare congenital disorder called maple syrup urine disease should limit their intake of BCAAs because their bodies cannot break them down properly Taking BCAA supplements is generally safe, but BCAA supplementation is not recommended for some people.

Branched-chain amino acid supplements may provide impressive benefits in certain circumstances, especially when it comes to muscle growth and physical performance.

However, BCAAs can also be found in whole protein supplements as well as in a large variety of protein-rich foods. Therefore, taking BCAA supplements may not be necessary, especially if you get sufficient amounts through your diet or a protein supplement. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

How Well Do You Sleep? Health Conditions Discover Plan Connect. When BCAAs were added as additional therapy to the ketogenic diet of children with refractory epilepsy, 13 out of 17 benefited, with a 50— percent seizure reduction compared to the ketogenic diet alone Evangeliou et al.

The authors suggested that BCAAs may not only increase the effectiveness of the ketogenic diet, but that the diet could be more easily tolerated by the patients because of the change in the ratio of fat to protein. Cole and colleagues reported that brain-injured mice exhibited cognitive improvement when treated with BCAA-supplemented drinking water each BCAA at a concentration of mM , beginning two days after injury Cole et al.

The injury was a 20 millisecond pressure pulse of saline to the dura, and hippocampal-dependent cognition was assessed using a conditioned fear response. In addition to behavioral assessments, Cole et al. The excitatory postsynaptic potentials generated in hippocampal slices from injured mice were diminished compared to sham controls, but incubating the slices with BCAAs at concentrations of μM fully restored synaptic function Cole et al.

Leucine and other essential amino acids are necessary, and their benefit in increasing protein synthesis and lean body mass is well documented. However, there are not yet compelling data to support a recommendation to supplement rations with BCAAs to ameliorate or treat TBI.

There is some indication from a pilot study that BCAAs might act synergistically with a ketogenic diet in epilepsy, one of the many possible sequelae of TBI. The only randomized clinical trial Ott et al. There is one encouraging animal study in which mice supplemented with BCAAs dissolved in water at mM showed improvements in cognition and diminished excitatory potentials in hippocampal slices Cole et al.

Taken altogether, however, there is not enough evidence from animal studies to support initiating research in humans. Because a large percentage of military personnel take BCAAs as supplements to their diets, BCAAs should be included in the dietary intake assessments of TBI patients in medical treatment facilities to identify preinjury nutritional intake and status, as well as nutritional intake during the various stages of treatment.

DoD should continue to monitor the literature on the effects of nutrients, dietary supplements, and diets on TBI, particularly those reviewed in this report but also others that may emerge as potentially effective in the future.

For example, although the evidence was not sufficiently compelling to recommend that research be conducted on BCAAs, DoD should monitor the scientific literature for relevant research.
