Research has shown supplemental BCAA intake to be safe for healthy adults in doses of 4-20 g per day, with prolonged intake one week or more showing greater benefits than acute (short term) intake. Aim for 2-3g leucine between meals, before, during or after workouts to maximize muscle protein synthesis.
While you don't need BCAAs at every meal, it is important to take them daily. This ensures you're getting all the nutrients you need so your body can function at its best. Branched-chain amino acids are most commonly found in protein-rich foods like milk, meat, and eggs.
Is expired protein powder safe to consume? The biggest risk to eating expired protein powder that looks, smells, and tastes fine is likely just the quality, Schaffner says. The manufacturer no longer promises a high-quality product after the expiration date, so you're risking eating a less-than product.
Whey protein contains all of the essential amino acids needed to build muscle. Therefore, while BCAAs can increase muscle protein synthesis, they can't do so maximally without the other essential amino acids, such as those found in whey protein or other complete protein sources ( 5 , 6 ).
Bottom line: Most vitamins are considered safe for up to two years past their expiration date (unless they contain mold), but may become less potent over time. Pregnant women and people in need of regular supplementation due to deficiency should talk to their doctor before relying on expired vitamins.
Without first working out, your body won't really need those resources, and you won't see the effects many have come to expect from BCAAs. There is, however, one possible exception to this: the energizing effects of an amino acid-based pre-workout supplement, such as the Fast Charge mix from aminoVITAL®.
As long as your protein powder has been stored properly, it will almost always be good beyond the printed sell-by date. The more time passes, the more likely there will be an issue. Even if the product doesn't go bad, some of the ingredients may deteriorate, and there may be a decline in the product's quality.
Expired multivitamins won't make you sick or cause any negative health impacts, but they won't provide the same volume or quality of nutrients promised on the label. Just like your favorite cooking spices, as vitamins age, they lose more potency—so, the older the multivitamin, the less potency it will provide.
The result of the current study shows that Exercise and/or BCAA can increase the level of testosterone. This result is in accordance with previous literatures that demonstrated testosterone level could significantly increase during overreaching training if accompanied by BCAA supplementation.
BCAAs may increase muscle mass After all, research shows that BCAAs do activate enzymes responsible for building muscle ( 25 ). Some studies also show that BCAA supplements may be effective at increasing muscle mass, especially if they contain a higher proportion of leucine than isoleucine and valine ( 25 , 26 ).
While you don't need BCAAs at every meal, it is important to take them daily. This ensures you're getting all the nutrients you need so your body can function at its best. Branched-chain amino acids are most commonly found in protein-rich foods like milk, meat, and eggs.
Consuming protein shortly after its expiration date is likely safe if there are no signs that it has gone bad, which include a rancid smell, bitter taste, changes in color, or clumping. If these signs are present, it's best to toss your tub and purchase a new one.
Can old pre workout make you sick? If your pre-workout is actually significantly past its use by date (not best before) it might cause some issues such as gastric distress - something you probably want to avoid in the gym! While this should pass pretty quickly, it is certainly unpleasant and should be avoided.

So, is it safe to whip up a protein shake using expired powder? In short, yes it is. But if the protein product, whether it's whey or vegan, smells or tastes off, or it's been a few months since its use-by date, treat yourself to a fresh pack and follow the storage instructions to the letter, to ensure its longevity.
