Creatine

Also known as: Creatine Monohydrate, Creatine Ethyl Ester, Buffered Creatine, Amino Acid Derivative

Amino AcidsPowderNatural Source

Creatine is a naturally occurring compound synthesized from amino acids that plays a critical role in energy production during high-intensity exercise. It is stored in muscles as phosphocreatine, which rapidly regenerates ATP (energy currency). Creatine is one of the most studied and effective sports supplements.

Benefits

Enhances athletic performance and muscle strength during high-intensity exercise. Increases muscle mass and supports muscle growth. Improves power output and training capacity. Supports brain health and cognitive function. May improve muscle endurance and recovery. Increases cellular energy availability. Supports mental health and mood.

Recommended Dosage

No established RDA. Common supplementation: Loading phase 20 grams daily (5 grams 4x daily) for 5–7 days, then 3–5 grams daily maintenance. Alternatively, take 3–5 grams daily without loading. Effects take 2–4 weeks to manifest. Creatine monohydrate is most studied and cost-effective. Take with carbohydrates and protein for absorption.

Food Sources

Red meat (beef), fish (salmon, tuna), poultry (chicken), eggs, milk, seaweed (small amounts).

Side Effects

Generally safe and well-tolerated. Mild side effects: water retention (1–2 pounds), bloating, stomach cramps, diarrhea, nausea. Some report muscle cramping. High doses may cause kidney stress (in those with predisposition). Hair loss reported anecdotally but not proven.

Interactions

May enhance effects of diuretics (dehydration risk). Interactions with standard medications unlikely at recommended doses. Caffeine may reduce creatine effectiveness. NSAIDs may reduce absorption. Works synergistically with beta-alanine and other performance supplements.

Warnings

Those with kidney disease should avoid or use only under medical supervision. Adequate hydration is essential during supplementation. Pregnant and breastfeeding women should avoid. Those taking cephalosporin antibiotics should monitor kidney function. Not recommended for children without medical guidance.

Deficiency Symptoms

Poor exercise performance and reduced muscle strength. Lower muscle mass and difficulty building muscle. Reduced energy availability during intense effort. Potential cognitive decline (in those with naturally low creatine).
