How Does Creatine Work?

Creatine supplements have become increasingly popular among fitness enthusiasts and athletes alike, as they are believed to improve strength, endurance, and muscle gains. But how exactly does creatine work in the body?

Adenosine triphosphate (ATP) is the primary source of energy for the body’s cells, including muscle cells. During high-intensity workouts, the body rapidly depletes its ATP stores, which limits the duration and intensity of exercise.

However, the body has a secondary source of energy in the form of phosphocreatine, a molecule that can quickly replenish ATP.

This is where creatine supplements come in. By increasing the body’s phosphocreatine stores, creatine supplements can help generate more ATP during exercise, allowing for longer, more intense workouts.

And while the body naturally produces creatine through the interaction between the amino acids glycine and arginine, supplementing with creatine can help optimize the body’s phosphocreatine stores.

But the benefits of creatine supplements go beyond just increased energy during exercise. Creatine can also improve cell signaling, reduce protein breakdown, and raise anabolic states, making it an effective tool for building muscle.

It’s worth noting that while muscle tissues do contain creatine stores, they are often not saturated. This is why many people will gradually load creatine into their system during a “loading phase,” where they gradually dose their creatine supplements multiple times daily.

This loading phase helps build creatine stores as high as possible, which can maximize the benefits of creatine supplementation.

When it comes to types of creatine supplements, creatine monohydrate is the most common and popular, and most of the research and science related to creatine supplementation is based on this type. However, other types of creatine supplements, such as creatine ethyl ester, creatine hydrochloride (HCL), creatine gluconate, buffered creatine, and liquid creatine, also exist.

Types Of Creatine

Creatine Monohydrate

Creatine monohydrate is the most extensively studied and commonly used type of creatine supplement. It’s just a single molecule of water combined with regular creatine for improved results.

Creatine Hcl

Creatine HCL is an advanced version of creatine with a hydrochloride molecule that has been added to increase its water solubility and absorption.

Creatine Citrate

Creatine citrate is creatine connected to citric acid. According to studies, it may have a higher degree of water solubility than CM. However, its efficacy and absorption remain the same as traditional forms of creatine supplementation.

Creatine Malate

Creatine malate is composed of one molecule of malic acid and three molecules of creatine, joined by an ester bond that promotes increased absorption. Unfortunately, it’s not the most economical choice for those on a budget.

Creatine Magnesium Chelate

The creatine magnesium chelate form of the supplement has been chemically bonded with magnesium, meaning that it is linked to a single creatine molecule. Nevertheless, further research is necessary to determine if magnesium offers a greater advantage compared to CM.

Buffered Creatine

Buffered creatine is supplemented with an alkaline powder for improved stability in the stomach. Despite claims that this supplement has a higher potency than CM, research indicates otherwise.

Creatine Ethyl Ester

Creatine ethyl ester is the same as creatine monohydrate, with an added ester – a compound formed when carboxylic acid and alcohols react. This modification is said to increase its absorptive potential and reduce bloating as well as dehydration.

Nevertheless, the ethyl group lessens acid stability and accelerates degradation, transforming creatine into creatinine.


How Long Does Creatine Last?

One question that is often asked is how long creatine lasts. A study conducted by the American Medical Association found that expiration dates greatly underestimated the product’s shelf life.

88% of the sample lots tested were extended past their marked expiry dates for an average of 66 months. This means that creatine supplements also have a longer shelf life than their expiration dates suggest.

Creatine Monohydrate, the most commonly used form of creatine, is incredibly stable and unlikely to break down into its waste product, creatinine. However, it is important to properly store the supplement to prevent physical change from environmental factors such as moisture, high temperatures, and open air, which can affect the product’s lifespan.

That said, there is promising data that suggests powdered creatine monohydrate can withstand high temperatures without degradation over many years. Even if the expiration date has passed, properly stored creatine monohydrate can last for years beyond its expiry date in the same tub in which it was manufactured.

Does Creatine Expire?

Creatine is a popular supplement among athletes and fitness enthusiasts, known for its ability to boost muscle strength and enhance exercise performance. However, as with many supplements, users often question whether creatine expires and if it is safe to consume after its listed date.

Scientific research has shown that creatine is an extremely stable compound that can remain effective long after its expiration date. While most creatine products do come with an expiration date, there is no need to worry about using them beyond this date.

Even if expired, creatine will primarily lose potency rather than cause adverse side effects in the consumer.

Among the various forms of creatine available, creatine monohydrate is the most stable and widely used by athletes. It has been extensively researched and proven to be highly stable over many years, which further validates its popularity.

In contrast, other forms of creatine such as liquid creatine or creatine salts are less stable and less researched. Liquid creatine, for instance, is highly dependent on pH levels and temperature, which can affect the rate of degradation.

Similarly, creatine salts can also affect the pH levels of the solution, making them less stable than creatine monohydrate.

In conclusion, creatine is a safe and effective supplement that can be consumed even after its expiration date, with creatine monohydrate being the most stable and reliable choice. While other forms of creatine may offer benefits, their stability and effectiveness are not as extensively researched, making creatine monohydrate the preferred choice for fitness enthusiasts and athletes alike.

When To Toss Your Creatine

When stored improperly, creatine may become clumpy and lose its intended consistency. This clumping is often the result of exposure to moisture, which can break down the product and cause it to become less effective. Nonetheless, clumpy creatine is still safe for consumption.

While expired creatine may still be safe to consume, it is important to pay attention to the quality of the supplement. If there is any noticeable change in the smell, color, consistency, or taste, it may indicate that the creatine has gone bad and should be discarded.

In addition to proper storage, it is important to consider the possibility of bacterial growth in creatine supplements. When exposed to significant moisture or left open for an extended period, bacteria can grow in the supplement and cause adverse side effects if ingested.

Therefore, it is crucial to store creatine in a clean, dry, and sealed container to prevent bacteria from flourishing.

In conclusion, proper storage is imperative in maintaining the effectiveness and potency of creatine supplements. While expired creatine may still be safe for consumption, it is important to use common sense and monitor for any changes in quality. With the right storage and precautions, athletes and fitness enthusiasts can continue to reap the benefits of creatine for their performance and overall health.

How To Store Creatine

To ensure that your creatine supplement stays potent and effective, it is important to store it properly. The packaging on the product should contain specific instructions for storage, which you should follow.

In general, it is best to store creatine powder in an airtight container in a cool, dry place where moisture cannot seep in. Exposure to moisture, even for a short period, can cause the supplement to break down into creatinine, which can be harmful to your health.

In addition to keeping your creatine dry, you should also avoid exposing it to direct sunlight or high temperatures, as these can accelerate the breakdown process. Ideally, you should store your supplements in a cool, dark place, such as a pantry or cupboard, away from any sources of heat or moisture.

Proper storage can significantly increase the shelf life of your creatine supplement, allowing you to use it safely and effectively even after its expiry date has passed. By following these simple guidelines, you can maximize the benefits of this powerful supplement and achieve your fitness goals with confidence.
