Understanding Creatine: How It Works and How to Supplement Safely

Creatine is one of the most well-researched and widely used dietary supplements among athletes and fitness enthusiasts. Creatine is renowned for its ability to enhance exercise performance, promote muscle growth, and aid in muscle recovery. In this blog post, we will delve into the science behind how creatine works and provide essential guidance on how to supplement with creatine safely and effectively.

How Creatine Works

1. ATP Regeneration

At the heart of creatine's mechanism of action lies its role in ATP regeneration. ATP acts as a fuel for your muscles during high-intensity physical activities. During exercise, muscles require a rapid supply of ATP to fuel the intense contractions. ATP is the primary energy currency of cells. During exercise, ATP gets depleted quickly, leading to fatigue.

Creatine helps aid ATP regeneration by donating a phosphate group to ADP (adenosine diphosphate), converting it back into ATP through a process called phosphorylation. This process ensures that muscles have an ample supply of ATP, allowing for sustained energy during short, intense bursts of activity.

2. Phosphocreatine (PCr) System

Our body stores creatine in the form of phosphocreatine (PCr) in muscle tissues. PCr acts as a readily available reserve of high-energy phosphate groups, providing immediate support in ATP regeneration. This mechanism is crucial for anaerobic activities like weightlifting, sprinting, and other explosive movements.

3. Muscle Cell Hydration

One of the additional benefits of creatine supplementation is its ability to draw water into muscle cells, leading to increased cell volume and hydration. It is important to note that many argue that the size gains seen in muscles is from its ability to carry water. However, this ability allows muscles to fire optimally by optimizing cell function and protein synthesis.

4. Protein Synthesis and Muscle Growth

Emerging research suggests that creatine may have a role in promoting muscle protein synthesis and muscle hypertrophy (growth). Creatine can assist in increasing the expression of certain proteins involved in muscle repair and growth. Creatine has the potential to enhance the body's ability to build and repair muscle tissues after exercise.

5. Lactic Acid Buffering

During intense exercise, the buildup of lactic acid in muscles can lead to fatigue and decreased performance. Creatine can act as a buffer by accepting protons released during ATP breakdown, therefore reducing the accumulation of lactic acid and delaying the onset of fatigue.

How to Supplement with Creatine

1. Choose the Right Form of Creatine

Creatine monohydrate is the most researched and widely used form of creatine. It is important to explore different forms, as it comes in gummies and powders. While other forms like creatine hydrochloride (HCL) and buffered creatine are available, they lack sufficient evidence to prove their superiority over creatine monohydrate.

2. Dosage

The standard dosage for creatine supplementation is 3 to 5 grams per day. Some individuals prefer a loading phase of 15-20 grams per day (split into 3-5 doses) for the first 5-7 days to saturate muscle creatine stores quickly. However, this phase is not necessary and may cause gastrointestinal discomfort (bloating) in some people. Therefore, a daily maintenance dose of 3-5 grams is sufficient for most users.

3. Timing

When to take it? Creatine can be taken at any time of the day, as its benefits are not contingent on the timing of ingestion. Some people prefer taking it pre- or post-workout for convenience, but it can be mixed with water or a I like to mix it into my post workout protein shakes.

4. Combine with Carbohydrates

Combining creatine with carbohydrates can enhance its uptake by muscles. Consuming creatine with a carbohydrate-rich beverage, such as fruit juice, protein shake, or a sports drink, can help optimize its effectiveness.

5. Stay Hydrated

Since creatine has a hydrating effect on muscle cells, it is essential to stay properly hydrated throughout the day. A tip I like to use is a hydration salt or increasing my sodium (salt) uptake. To do this I often use drip drop mixed into my water while working out. Drink sufficient water to support creatine's action and to prevent any potential side effects related to dehydration.

Creatine is a safe and effective supplement for enhancing exercise performance, muscle growth, and recovery. Understanding how creatine works allows you to harness its benefits properly. When supplemented wisely, creatine can be a valuable tool in achieving your fitness goals. As with any supplement, it is recommended to consult with a healthcare professional before starting creatine supplementation, especially if you have any underlying health concerns. With the right approach, creatine can become an essential part of your fitness journey.
