Safe: It's a remarkably safe supplement that helps bodybuilders gain muscle mass.
Dr. Dean Giannone
Internal Medicine 25 years experience
Creatine.: Creatine in doses of 1000 to 5000mg daily has been shown to increase muscle mass, muscle size and muscle energy stores. Creatine must be taken with lots of water throughout the day, and doses must not exceed 5000mg daily to avoid impairment of kidney function. The dose can be taken all at once, preferably after exercise to facilitate ATP store replenishment in the muscles after exercise.

Not sure: Studies are very inconsistent on creatine intake especially in young athletes going to the gym. While a study done in 2005 by pline et al showed no effect on kidney function, creatine role and influence in elderly and people with impaired kidney function is still unknown. I personally do not recommend it to my patients

Generally, Few: Creatine can cause an increase in water weight. It has been associated with stomach pain, nausea, diarrhea, and muscle cramping. There is some concern that it could harm the kidney, liver, or heart function. Drink extra water. If you are taking creatine, don't exercise in the heat. It might cause you to become dehydrated. Do not use if you have kidney disease, diabetes, or may be pregnant.

What does 1.43 creatine level mean? I'm)

Renal or Kidney role: Hi a creatine level at 1.43 would represent what we call 'renal insufficiency syndrome'. It could be that your kidneys are under strain and are not cleaning the blood of all of the toxins that it should. It could mean your kidneys are beginning to fail. If you do not have a relationship with the appropriate health care provider to protect your kidneys and treat the underlying disease get one!

A 19-year-old male asked:

Is creatine bad for bodybuilders to take ? And what does it cause ?

1 doctor answer3 doctors weighed in
Dr. Brian Badman
Orthopedic Surgery 25 years experience
No: Creatine when taken appropriately can help with muscle recovery. It will cause water retention and the biggest risk of taking this is muscle cramping from insufficient hydration. If you are taking this as a supplement you need to make sure you are staying adequately hydrated. Otherwise it has not had any long term notable side effects as it is excreted by your kidneys.
A 48-year-old member asked:

Help docs? Why is creatine considered bad?

1 doctor answer1 doctor weighed in
Dr. Stuart Winkler
Nephrology and Dialysis 48 years experience
Creatine: Ingesting too much creatine may induce diarrhea, kidney damage and liver damage. Creatine is brocken down into formaldehyde which theoretically is toxic to tissue. However ingestion of as much as 3 grams of pure creatine per day has not been associated with risk however the long term effects are not known.
