What is Creatine?

Creatine is a naturally occurring compound found in muscle cells and the brain. It is made from three amino acids: arginine, glycine, and methionine.

Its primary role in the body is to help produce ATP (adenosine triphosphate) — the molecule cells use for energy.

Because ATP powers muscle contraction and cellular activity, creatine plays an important role in:

• Muscular performance
• Brain energy metabolism
• Cellular energy production

Creatine is naturally present in foods such as red meat and fish, but supplementation has become widely used for athletic performance and cognitive support.

Ageless Cocktail by Longevity Farms includes 2 grams of creatine monohydrate per serving, alongside NMN, NAD+, and other ingredients designed to support metabolic energy pathways.

Creatine Monohydrate by Longevity Farms is also available.

How Creatine Works in the Body

Creatine works through the phosphocreatine system, one of the body’s fastest ways to regenerate ATP.

The process works like this:

1. Creatine is stored in cells as phosphocreatine.

2. During energy demand, phosphocreatine donates a phosphate molecule.

3. This regenerates ATP, the cell’s primary energy currency.

This system is particularly important for:

• High-intensity physical activity
• Muscle contraction
• Brain energy metabolism

Creatine also plays a role in mitochondrial function and cellular energy buffering, which is why it has gained interest in longevity and cognitive research.

Benefits of Creatine

Cellular Energy

Creatine helps maintain ATP levels during periods of high energy demand. This supports both muscular and neurological energy metabolism.

Brain Performance

Creatine is present in the brain and may support cognitive processes that require high metabolic energy, such as memory and mental fatigue resistance.

Muscle Performance

Creatine supplementation is widely used to support strength, power output, and muscle recovery.

Creatine Research

Creatine is one of the most extensively studied supplements in the world, with hundreds of clinical studies examining its effects.

How to Take Creatine

Creatine is most commonly supplemented as creatine monohydrate.

Typical dosing protocols include:

• 3–5 grams daily for maintenance
• Optional loading phase of 20 grams daily for 5–7 days

Creatine can be taken with water, juice, or mixed into beverages.

Creatine vs Other Energy Compounds

Creatine differs from compounds like NMN or NAD+ because it directly supports ATP regeneration rather than influencing cellular signaling pathways.

These compounds can complement each other in energy metabolism stacks.

Creatine Supplement Sources

Creatine is naturally found in foods such as:

• Red meat
• Salmon
• Tuna

However, dietary intake often provides only 1–2 grams per day, which is why supplementation is commonly used.

Products Containing Creatine

Some formulations combine creatine with compounds that support cellular metabolism and mitochondrial function.


Ageless Cocktail by Longevity Farms includes 2 grams of creatine monohydrate per serving, alongside NMN, NAD+, and other ingredients designed to support metabolic energy pathways.

Creatine Monohydrate by Longevity Farms is also available.

Creatine FAQ

What does creatine do in the body?
Creatine helps regenerate ATP, the primary energy molecule used by cells. This allows muscles and the brain to maintain energy during periods of high demand.

Is creatine only for athletes?
No. Although creatine is widely used for athletic performance, research has also explored its role in brain energy metabolism, cognitive performance, and healthy aging.

Is creatine naturally produced by the body?
Yes. The body synthesizes creatine from the amino acids arginine, glycine, and methionine. It is also obtained from dietary sources such as meat and fish.

What foods contain creatine?
Creatine occurs naturally in red meat, salmon, and tuna. However, typical dietary intake is relatively low compared with amounts used in supplementation studies.

What is the most common form of creatine?
Creatine monohydrate is the most widely studied and commonly used form of creatine supplementation.

How much creatine is typically taken?
Many supplementation protocols use 3–5 grams per day. Some individuals use an optional short loading phase of around 20 grams daily for 5–7 days before transitioning to a maintenance dose.
