Health Notes

Creatine Monohydrate

Creatine Monohydrate
This nutrient has been used in connection with the following health goals
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

Chronic Obstructive Pulmonary Disease
Dose: 5 grams three times a day for two weeks, and then 5 grams once daily
Creatine has been shown to increase muscle strength, muscle endurance, and overall health status.(more)
High Cholesterol
Dose: Refer to label instructions
One trial found that supplementing with creatine significantly lowered serum total cholesterol and triglycerides in people with high cholesterol.(more)
High Triglycerides
Dose: Refer to label instructions
One trial found that supplementing with significantly lowered serum total triglycerides in both men and women.(more)
Athletic Performance and Non-Weight Bearing Endurance Exercise
Dose: 15 to 20 grams daily for five or six days
Taking this supplement for five or six days may improve performance of high-intensity, short-duration exercise (like sprinting) or sports with alternating low- and high-intensity efforts.(more)
Athletic Performance and High-Intensity, Short Duration Exercise or Sports with Alternating Low- and High-Intensity Efforts
Dose: 15 to 20 grams a day for five or six days
Supplementing with creatine may improve performance of non-weight bearing endurance exercises such as cycling.(more)
Chronic Obstructive Pulmonary Disease
Dose: 5 grams three times a day for two weeks, and then 5 grams once daily

In a double-blind study, people with COPD received creatine or a placebo for 12 weeks. After the first 2 weeks of supplementation, all participants underwent an outpatient pulmonary rehabilitation program. Compared with the placebo, creatine significantly increased muscle strength, muscle endurance, and overall health status, but not exercise capacity.1 The amount of creatine used in this study was 5 grams three times a day for 2 weeks, and then 5 grams once a day for 10 weeks.

High Cholesterol
Dose: Refer to label instructionsA double-blind trial found that 20 grams per day of creatine taken for five days, followed by ten grams per day for 51 days, significantly lowered serum total cholesterol and triglycerides, but did not change either LDL or HDL cholesterol, in both men and women.1 However, another double-blind trial found no change in any of these blood levels in trained athletes using creatine during a 12-week strength training program.2 Creatine supplementation in this negative trial was lower-only 5 grams per day were taken for the last 11 weeks of the study.

High Triglycerides
Dose: Refer to label instructions

A double-blind trial found that a supplement of 5 grams of creatine plus 1 gram of glucose taken four times per day for five days followed by twice a day for 51 days significantly lowered serum total triglycerides in both men and women.1 However, another double-blind trial found no change in any of these blood levels in trained athletes using creatine during a 12-week strength training program.2 Creatine supplementation in this negative trial was lower-only five grams per day was taken for the last 11 weeks of the study.

Athletic Performance and Non-Weight Bearing Endurance Exercise
Dose: 15 to 20 grams daily for five or six days

Creatine (creatine monohydrate) is used in muscle tissue for the production of phosphocreatine, a factor in the formation of ATP, the source of energy for muscle contraction and many other functions in the body.1, 2 Creatine supplementation increases phosphocreatine levels in muscle, especially when accompanied by exercise or carbohydrate intake.3, 4 It may also increase exercise-related gains in lean body mass, though it is unclear how much of these gains represents added muscle tissue and how much is simply water retention.5

Over 40 double-blind or controlled studies have found creatine supplementation (typically 136 mg per pound of body weight per day or 15 to 25 grams per day for five or six days) improves performance of either single or repetitive bouts of short-duration, high-intensity exercise lasting under 30 seconds each.6, 7, 8, 9, 10, 11, 12 Examples of this type of exercise include weightlifting; sprinting by runners, cyclists, or swimmers; and many types of athletic training regimens for speed and power. About 15 studies did not report enhancement by creatine of this type of performance. These have been criticized for their small size and other research design problems, but it is possible that some people, especially elite athletes, are less likely to benefit greatly from creatine supplementation.13

Fewer studies have investigated whether creatine supplementation benefits continuous high-intensity exercise lasting 30 seconds or longer. Five controlled studies have found creatine beneficial for this type of exercise,14 but one study found no benefit on performance of a military obstacle course run.15 Most studies of endurance performance have found no advantage of creatine supplementation, except perhaps for non-weight bearing exercise such as cycling. 16, 17, 18

Long-term use of creatine supplementation is typically done using smaller daily amounts (2 to 5 grams per day) after an initial loading period of several days with 20 grams per day. Very little research has been done to investigate the exercise performance effects of long-term creatine supplementation. One study reported that long-term creatine supplementation improved sprint performance.19 Four controlled long-term trials using untrained women,20 trained men,21 or untrained older adults found that creatine improved gains made in strength and lean body mass from weight-training programs.22, 23 However, two controlled trials found no advantage of long-term creatine supplementation in weight-training football players.24, 25

Creatine supplementation appears to increase body weight and lean body mass or fat-free mass, but these measurements do not distinguish between muscle growth and increased water content of muscle.26, 27 A few double-blind studies using more specific muscle measurements have been done and found that combining creatine supplementation with strength training over several weeks does produce greater increases in muscle size compared with strength training alone.28, 29, 30

Comments about GNC Pro Performance® AMP Amplified Creatine XXX™ Ripped - Fruit Punch:

I got this because I was looking to change up my creatine regime and thought the ripped blend would be a good fit for my current goals. Unfortunately, this tastes so bad (seriously, do NOT smell the container or you won't want to go near it) I couldn't get through more than 2 servings before returning it. It is likely the CEE in this one, as that is noted for tasting terrible, but I have had all kinds of supplements before and not experienced anything this bad.

Additionally, both times I took it I noticed feeling bloated and some stomach discomfort afterwards. It could be a coincidence, but this was the only change in my regime at the time. And I suppose one maybe adjusts to it, but at the AMP XXX price point, there's no reason to spend time on something that taste horrible and can make you feel bloated (the opposite of ripped).
