How much reatine should i take?

For healthy adults using creatine monohydrate, either load with 20 g/day (4 x 5 g) for 5–7 days then maintain 3–5 g/day, or skip loading and take 3–5 g/day from the start—timing is flexible, daily consistency matters most. There are several factors to consider (hydration, mild GI effects, and medical considerations like kidney/liver disease, certain meds, and youth); see the complete details below and consult a clinician if you have conditions or plan higher doses.

How much creatine should I take?

Creatine monohydrate is one of the most researched and effective supplements for improving strength, power and muscle mass. According to the 2017 International Society of Sports Nutrition position stand (Kreider et al., J Int Soc Sports Nutr), it’s safe and effective when used correctly by healthy adults. Below is a practical, evidence-based guide to dosing, timing and safety.

  1. Standard dosing strategies
    There are two common ways to load and maintain creatine levels:

    • Loading phase + maintenance

    • Loading: 20 g per day, divided into four 5 g servings, for 5–7 days.
    • Maintenance: 3–5 g per day thereafter.
    • Benefit: Faster muscle creatine saturation (within 1 week).

    • No-load (steady) dosing

    • Simply take 3–5 g per day from day one.
    • Benefit: Similar muscle saturation over ~3–4 weeks, fewer digestive issues.
  2. Timing and how to take it
    • Any time of day will eventually raise muscle creatine levels if you stick to daily dosing.
    • Some athletes prefer post-workout with a carb/protein meal to enhance uptake, but the effect size is small.
    • Mix creatine powder into water, juice or a shake; it dissolves easily in warm liquids.

  3. Who can benefit?
    • Athletes in high-intensity, short-duration sports (sprints, weightlifting, basketball).
    • Older adults looking to preserve muscle mass and strength.
    • Vegetarians/vegans (often have lower baseline creatine stores).

  4. Safety and side effects
    • Extensive research shows creatine monohydrate is safe in healthy people when taken at recommended doses (up to 5 g/day long-term).
    • Common mild side effects:
    – Bloating or water retention (temporary)
    – Stomach discomfort (more common during loading)
    • To minimize issues:
    – Split loading doses (4×5 g) rather than one big dose
    – Stay well-hydrated (creatine pulls water into muscle cells)

  5. Special considerations
    • Kidney or liver concerns:
    – In healthy adults, creatine does not impair kidney or liver function.
    – If you have known kidney disease or liver disease (e.g., cirrhosis), check with your doctor first. Non-invasive liver assessments (Castera et al., Hepatology) and survival models (Kamath & Wiesner, Hepatology) underscore the need for medical guidance in advanced liver disease.
    • Children and adolescents:
    – Research is limited. Consultation with a pediatrician or sports medicine specialist is recommended before use.
    • Medications:
    – If you’re on diuretics, NSAIDs or other chronic meds, discuss creatine with your physician to avoid interactions.

  6. Monitoring your response
    • Track performance metrics (strength, sprint times) to gauge benefit.
    • Note any digestive issues or unusual symptoms. If you experience anything concerning, consider doing a free, online symptom check for gastrointestinal or kidney discomfort.
    • Keep a log of daily intake and any side effects.

  7. Practical tips for success
    • Buy micronized creatine monohydrate—pure, unflavored, from a reputable brand.
    • Store in a cool, dry place; avoid exposure to moisture.
    • Pair creatine with a balanced diet rich in protein and complex carbs.
    • Combine with a structured training program for best results.

  8. When to seek medical advice
    • Sudden or severe side effects (e.g., significant abdominal pain, unexplained swelling).
    • Pre-existing kidney, liver or heart conditions.
    • If you plan to exceed recommended doses or combine with other supplements.

Remember, while creatine is one of the most studied sports supplements with a strong safety profile in healthy adults, individual responses can vary. Always:

  1. Follow recommended dosing (3–5 g/day maintenance).
  2. Stay hydrated.
  3. Track your body’s response.
  4. Speak to a doctor before starting supplementation if you have any medical conditions or are taking medications—especially anything that could be life-threatening or serious.
