Special Populations

Certain groups should exercise caution with creatine:

Nutritional Context of Creatine

Creatine is a compound that’s important for energy production in muscle cells, occurring naturally in some foods, particularly in meat and fish, and is also synthesised in the human body from amino acids.

Creatine in Diet

Creatine is found in various dietary sources, especially in animal products. Here is a succinct overview:

Note: The creatine content can vary depending on the cooking method, with raw sources containing higher amounts than cooked. Vegetarians and vegans may have lower creatine levels due to the absence of meat and fish from their diet.

Interaction With Other Nutrients

Creatine interacts with various nutrients that can affect its storage and utilisation:

Ingestion of creatine supplements, coupled with carbohydrate or carbohydrate and protein, has shown to be more effective in increasing muscle creatine stores than creatine alone.

Note: A balanced diet that includes adequate amounts of macronutrients may help to optimise the body’s natural creatine levels and the effectiveness of creatine supplementation.

Creatine Supplementation Protocols

Creatine supplementation involves specific phases for optimising creatine stores in muscles. These phases ensure adequate muscle saturation and support muscle growth while considering potential weight gain.

Loading Phase

The loading phase is designed to rapidly maximise muscle creatine stores. Individuals typically consume 20 grams of creatine per day, divided into four 5-gram servings, over 5–7 days. During this phase, some may experience an increase in body weight due to water retention.

Maintenance Phase

Post-loading, the maintenance phase sustains elevated creatine levels. A common practice is the intake of a 3–5 gram daily dose, which is sufficient to maintain the muscle’s creatine stores. This phase seamlessly follows the loading phase, continuing indefinitely to support workout performance.
