How do creatine supplements affect blood pressure during weight training?

High Cholesterol A preliminary study suggests that creatine supplements may help lower levels of blood lipids (cholesterol) in men and women with abnormally high concentrations of lipids in their blood. Congestive Heart Failure (CHF) In a few studies of people with congestive heart failure, those who took creatine (in addition to standard medical care) had significant improvement in symptoms and exercise capacity compared to those who received placebo. A February 2002 study published in the journal Medicine and Science in Sports & Exerciseexamined 15 males and 15 females in a randomized, double-blind experiment that administered 20 grams of creatine per day for five days. There was no increase in blood pressure among the subjects receiving creatine. Considering the limited amount of clinical studies in this area, this single study should not be interpreted as conclusive.
