Is it bad to take creatine at a younger age?

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.

Football and track )has increased tremendously in the past 15 -20 years.Some studies suggest increase performance w/ creatine use in short, " burst" type activities such as sprinting.They are" legal" by ncaa ; but cannot be dispensed by the college.Side effects?Cramping/wt. Gain.

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!
