Understanding Creatine
Creatine is a molecule that is made naturally in the human body and helps supply energy to cells, particularly muscle cells. It plays a key role in providing quick bursts of energy during weight lifting or sprints. Creatine can also be obtained through certain foods or supplements.
Meat and Fish
Some of the best dietary sources of creatine include meat and fish. In particular, foods that are especially high in creatine include:
- Wild game meat
- Grass-fed beef
- Organ meats like liver or kidneys
- Fatty fish like salmon, tuna, or mackerel
- Herring
For people who eat meat and fish regularly, these foods may provide enough creatine to meet the body's needs without requiring supplements.
Vegetarians and Vegans
People who follow vegetarian or vegan diets are more likely to be deficient in creatine since their main sources of it are animal products. However, some plant-based foods also contain small amounts of creatine, including:
- Wheat germ and wheat bread
- Spirulina
- Raw cacao powder
- Roasted sesame seeds
- Hemp seeds
- Chia seeds
While these foods do have modest amounts of creatine, vegetarians or vegans would likely still need to take creatine supplements to reach optimal levels.
Should I Take Creatine Supplements?
Deciding whether or not to take creatine supplements will depend largely on your diet, lifestyle, and fitness goals.
Benefits of Creatine
Here are some evidence-backed benefits of taking creatine:
- Increase muscle mass and strength output
- Enhance high-intensity athletic performance
- Help speed muscle recovery
- Improve brain health and function
- Reduce fatigue and tiredness
Those who tend to benefit the most from creatine are:
- Weight lifters
- Sprinters and power athletes
- Team sports players
- Middle-aged adults wanting to preserve muscle mass
- Vegans and vegetarians
Potential Risks
While generally safe when taken properly, potential side effects can include:
- Weight gain from extra water retention
- Muscle cramping or strains
- Kidney stress
- Digestive issues like diarrhea
Creatine may also interact with certain medications and increase risk of injury if improper form is used when strength training.
How to Supplement with Creatine
For those looking to maximize creatine's benefits, supplementing with creatine monohydrate powder can more reliably increase muscular creatine stores compared to obtaining creatine solely from foods.
Recommended Dosage
Most research on creatine suggests the following dosage guidelines:
- Loading phase: Take 20 grams per day split into 4 doses of 5 grams each for 5-7 days.
- Maintenance phase: Take 3-5 grams per day with food.
- Take creatine with a carbohydrate source, as this may help absorption.
- Consider cycling on and off creatine, taking 3 months on 1 month off.
When to Take It
Its generally recommended to take creatine supplements:
- Right before or after workouts on training days.
- In the morning on non-training days.
- With a quick carbohydrate source like fruit or fruit juice.
Timing creatine this way can help maximize uptake by muscles and minimize side effects.
Is Creatine Safe?
Multiple long-term studies show creatine is likely safe to take for up to 5 years. However, due to limited data, creatine cannot yet be deemed safe for life-long use.
To reduce risk when supplementing:
- Drink extra water daily to stay well hydrated.
- Don't exceed suggested dosages long-term.
- Inform your doctor if taking other medications or if you have liver or kidney conditions.
- Closely monitor kidney function with a doctor while on creatine.
The Bottom Line
Getting adequate creatine from meat/fish or supplements can enhance exercise performance, muscle gain, brain function, and recovery. But improper use does pose some health risks.
Speak to a doctor or dietitian to decide if creatine is right for your goals.
FAQs
What foods contain the most creatine?
The foods highest in creatine are wild game meats, grass-fed beef, fatty fish like salmon, and organ meats like liver or kidneys. For vegetarians, foods like wheat germ, spirulina, and hemp seeds have modest amounts.
Is creatine found in any fruits or vegetables?
No, fruits and vegetables generally do not contain creatine. Only animal products like meat and fish or certain supplements like spirulina provide creatine.
What factors influence how much creatine is in meat?
Grass-fed beef contains more creatine than grain-fed. Wild game meat and organ meats also have higher creatine content. Cooking may slightly reduce meat’s creatine content.
Can vegetarians get enough creatine from plant foods?
It's unlikely. While small amounts of creatine are found in seeds, wheat germ and algae, a vegetarian would still likely need to take creatine supplements to reach optimal levels.
