Ah man, there is no one answer for this. Some say yes (but a decreased potency) and others say no as it has turned into creatinine. I disagree with the latter answer. My suggestion is try it, if it upsets your stomach, throw it away. If it doesn't, check if it is doing anything for you. Do this by weighing yourself prior to taking the creatine, and 2 weeks later weigh yourself again. If you are loading the creatine, you should have gained about 1.5 -2kgs of weight (that is water rentention). Then you know it is working and serving its purpose.
It's best not to take risks and discard expired supplements. Expired creatine is probably not dangerous, only less effective and/or less potent. There's no reason why creatine (expired or not) would damage your liver. Unless some bacteria have begun to form, the creatine would probably not be dangerous. Most supplements do carry an expiration date, and it's probably just good practice to follow these dates. To be on the safe side, you should discard expired creatine or any other supplements. At the same time, don't fret if you did consume some of the expired creatine.
Not very effective
Creatine Monohydrate. It's cheap and effective. If you are getting the right product, it should be AROUND $20 for 1000 grams.
They're not. Hence EXPIRED. Go see your doctor.
A year after expired date so says the folks at Forest Laboratories. After that may not be as effective.
yes, it will just be less effective.
Creatine is one of the most highly recommended supplements for body builders. Creatine not only helps build muscle, it provides energy for more effective workouts.
Expired medication will likely work just fine and is unlikely to hurt you. It may be less effective.
The chemical formula of creatine kinase is C208H332N65O104P.
It's not just during pregnancy expired medicine should never be used. Return it to the doctor or pharmacy. It's not effective or less effective so you don't know how much you get if any.
Birth control suppositories are one of the least effective methods to begin with. Withdrawal is more effective than spermicide used alone. Consider getting some condoms and throwing out the expired suppositories.
Vitamins are totally different things to creatine. Good sources for creatine are fish and red meat. If you are willing you can also look into supplementing creatine. Creatine monohydrate is the most proven type of creatine supplement.
