Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: creatine monohydrate, a compound your muscles naturally use for energy during intense exercise. It's designed to boost muscle stores of creatine, which may support strength and athletic performance.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: improving explosive exercise and increasing muscle mass.
  • We looked for evidence on: Athletic performance, Muscle strength, Physical performance, Muscle breakdown, Sarcopenia, HIV/AIDS-related wasting — and 3 related terms.
  • The strongest evidence on file: Creatine is rated "Possibly Effective" for Athletic performance (Natural Medicines).
  • Also on file: Creatine is rated "Possibly Effective" for Muscle strength, Sarcopenia.
  • Also on file: Creatine is rated "Insufficient Reliable Evidence To Rate" for HIV/AIDS-related wasting, Muscle breakdown, Physical performance.

The evidence behind creatine monohydrate is mixed. It's possibly effective for muscle strength, athletic performance, sarcopenia (age-related muscle loss), and cerebral creatine deficiency syndromes.

However, for Huntington disease and osteopenia (low bone density), the evidence suggests it's likely ineffective. Most of the positive data comes from people doing resistance training or high-intensity exercise.

The evidence, ingredient by ingredient Creatine

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Creatine is generally well tolerated in healthy adults. The most common side effects are dehydration, diarrhea, stomach upset, muscle cramps, and water retention — usually mild.

Rare serious concerns like kidney injury and muscle breakdown have been reported in case studies, but large clinical trials haven't confirmed these as common risks. If you have kidney disease or reduced kidney function, talk with your doctor or pharmacist before starting; caution is warranted.

Safety data during pregnancy and breastfeeding is insufficient, so avoid use if you're pregnant or nursing.

General Statements

Creatine: The latest info on Creatine Creatine supplementation provides an extensive list of well known benefits which include improving explosive bouts of excercise, decreasing myostatin levels and increasing muscle mass without side effects when taken properly.† However, there is a lot to creatine that you may not be aware of. If you’ve heard of myostatin, then you know that it is a protein in the body discovered in 1997 that is responsible for regulating muscle growth by inhibiting it. Based on genetics, there are myostatin levels that vary from person to person that can cause one to be a world class bodybuilder and another a hard gainer. Everyone knew that creatine helped to increase strength, but was the increase in strength what lead to the gains in muscle? Or was it something else? Researchers from Tarbiat Modares University discovered that when combined with resistance training, creatine actualy helped to inhibit serum levels of mysostatin! This research comes as somewhat of a surprise, but the reason it was quickly accepted by many is that myostatin also worked by inhibiting satellite cell formation. And back in 2000, researchers from the University of Wisconsin Medical School discovered that creatine does the exact opposite of that. Satellite cells are myogenic cells responsible for postnatal growth and regeneration of skeletal muscle. Stimulating these cells through training and supplementation is of the upmost importance for lifters looking to build muscle. Another important capability of creatine is its effect on recovery from high intensity exercise. You’ve heard of bodybuilders neglecting the use of creatine in the past because they weren’t lifting for strength or power. They felt creatine was only effective for increasing strength (which as you’ve read so far, is only part of what creatine does) and it had no place in their 8-12 rep, high intensity bodybuilding program. It has long been tradition in many bodybuilding programs to use short rest periods, and because creatine takes upwards of 2 minutes to regenerate, some ill informed bodybuilders have not seen it as a necessary supplement in their regimen. Well research begs to differ; high intensity anaerobic exercise is notorious for depleting muscle glycogen because carbohydratesare the main source of fuel for high intensity activities. Bodybuilders consume carbohydrates post exercise along with their protein to refill their muscles depleted stores of carbohydrates so they can return to the gym and lift with the same intensity. Bodybuilders may notice however that when they do heavy multi-joint lifts (like the squat, or the deadlift), or they lift at a slower pace, it takes them longer to recover. This is a result of the eccentric (lowering portion) phase of the lift which causes moremuscle damage and inflammation; many experienced lifters know this already, what they may not know is that eccentric exercise also impairs glycogen replenishment! Yet low and behold researchers from the Exercise Physiology and Biomechanics Laboratory of Katholieke Universiteit Leuven in Belgium discovered that supplementing with creatine helps preserve muscle glycogen by increasing creatine utilization during exercise (the researchers used 5g of creatine a day with no loading phase). In case you were wondering if creatine cycling was a real issue, the researchers found out the hard way as the increase in muscle glycogen they noted vanished after 5 weeks despite continued creatine supplementation. So cycling on and off creatine during your training cycles is still a good idea.

Delay Fatigue† Boost Power Output & Maximize Absorption† Support Increases in Strength Muscle Mass & Volume† REDUCES MYOSTATIN FOR TRIGGERING MUSCLE GROWTH†

ENHANCE ATHLETIC PERFORMANCE & INCREASE ATP†

BENEFITS OF CREATINE SUPPLEMENTATION • Increase muscle mass by stimulating satellite cells (satellite cells are ‘blank’ cells that aid in tissue regeneration).† • Increase strength by elevating creatine phosphate levels.† The elevation of creatine phosphate leads to an increase in the formation of ATP, which is natures natural energy source. • Reduce fatigue and promote exercise recovery by reducing muscle glycogen depletion.† The higher the availability of creatine in the body, less muscle glycogen is necessary during intense strength training exercises. • Increase muscle volume†: increased intramuscular creatine stores draw water to properly hydrate muscle and improve muscle volume. FALLACIES OF CREATINE SUPPLEMENTATION Creatine is not good for outdoor sports: this is contradictory to the research. It is normally thought that creatine can lead to dehydration and muscular cramping. However, there isn’t a research proven link between cramping during athletic events and creatine use. What research has shown however is that increased hydration levels in muscle lead to your body’s ability to handle higher outdoor training levels. While it is true that your water requirement will go up due to increased intramuscular water, water has the ability to regulate temperature which will be to your advantage during outdoor activities. Creatine will also aid in boosting sports performance.

Suggested/Recommended/Usage/Directions

Recommended Usage: Mix 5 grams of Creatine Micronized with water or juice either with a meal, post-workout, or pre-workout. Continue the use of Creatine on non-training days as well to maintain muscle saturation. Creatine levels will decline and return to normal after 30 days. Creatine supplementation is also important for the elderly to support lean mass and functional strength. Loading & Cycling: If you’re an athlete or advanced lifter who is interested in loading creatine to increase phosphate levels quickly, use 20 grams (4 servings) a day for the first 4-5 days. Discontinue use after 4 weeks, and repeat after at least 4 weeks of discontinued use. Creatine effectiveness plateaus after 4-5 weeks of continuous use.

Creatine Micronized by Betancourt Nutrition: Common Questions

Does Creatine Micronized by Betancourt Nutrition interact with any medications?
We do not currently list a known interaction for the mapped ingredients in Creatine Micronized. This does not guarantee none exist, so confirm with your pharmacist.
How can one product interact with so many drugs?
Creatine Micronized contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will creatine make me retain water?
Water retention is one of the most common side effects. Creatine pulls water into muscle cells, which is part of how it works — some people notice mild bloating or a slight weight gain early on. This usually isn't harmful, but if it bothers you, mention it to your doctor.
Can I take this if I have kidney disease?
The safety notes advise caution for people with kidney issues. Because your kidneys process creatine, it's worth talking with your doctor or pharmacist first to make sure it's appropriate for your specific situation.
Is creatine safe if I'm pregnant or breastfeeding?
Safety data during pregnancy has not been established, so it's best to avoid it. There also isn't enough safety information for nursing mothers, so avoid use while breastfeeding. Talk with your doctor or pharmacist if you have questions about your individual situation.
What are the side effects I should watch for?
Most people experience mild side effects like dehydration, diarrhea, stomach upset, muscle cramps, or water retention. Serious concerns like kidney problems or muscle breakdown are rare but have been reported — if you notice any unusual symptoms, stop taking it and contact your doctor.
Does creatine actually improve athletic performance?
The evidence says it's possibly effective for athletic performance. It works best if you're doing resistance training or high-intensity exercise — it won't help much for endurance or casual activity.
