Does Creatine Expire? Can Creatine Go Bad?

Creatine supplement is taken by many athletes to improve muscle development. It is an organic acid used to provide an energy source for muscle contraction.

This supplement’s use has been very popular in the sport of cycling since it increases ATP production to produce a higher power output. There are many benefits to the use of creatine. (1)

With so many benefits and creatine being in supplement form, people often question if creatine expires? What happens when we take expired creatine? Can Creatine Really Go Bad?

Does Creatine Expire? Yes, Creatine Does Expire. But if you store it well in dark and dry places away from moisture, you can consume them even for 2 years after their expiry dates.

Does Creatine Expire

If the creatine monohydrate supplements are in a cool and dark place, then you can even take them after 2 years from their expiration date. The second factor is the form you have your creatine in. (6)

Like a creatine powder can stay well for even more than 2 years, but if it’s in a liquid form it might not stay long after its expiration. Make sure you are consuming it before the expiry date.

There is a study that shows that creatine was put at a high temperature of 60°C for as long as 4 years. But even these extreme conditions didn’t have any negative impact on the creatine supplement.

While this is only true for the creatine monohydrate form, other types like creatine ethyl ester, liquid creatine are not very stable and will undergo transformation into creatinine soon once they cross expiration dates. (7)

Can Creatine Really Go Bad?

Creatine is a common supplement used by athletes and bodybuilders to help increase muscle mass and strength. But can creatine really go bad? The answer is yes, it can.

When creatine is stored for long periods of time or exposed to high temperatures, it can break down and form creatinine, a by-product that can be harmful to the kidneys. So, if you’re using creatine, be sure to use it within the expiration date and store it in a cool, dry place.

So, we can say that nothing will happen to your creatine supplement within 1-2 years after expiration if stored in the right conditions.

So, it is advisable to keep your creatine supplement powder away from direct sunlight.
