Time Stamps:

02:00 Creatine draws water into cells.

04:00 Creatine and the phosphagen system are an ATP buffer for short term high intensity activities.

05:10 High intensity activities utilize creatine.

06:10 Creatine helps with the resynthesis of ATP during short duration high intensity exercise.

06:45 Hydration and plasma volume improves with creatine.

08:45 Creatine was discovered in 1835 in meat.

09:00 Creatine is stored in the placenta and impacts female hormones.

12:11 Renal function is not negatively impacted by creatine.

14:00 Creatine is osmotically active and alters body fluid dynamics.

14:40 Two to 5 grams per day around exercise should be sufficient.

15:10 Creatine does not promote muscle cramps or dehydration.

16:00 It does not hinder thermal regulation.

19:30 Creatine increases intracellular, extracellular, and total body water.

20:10 Creatine is associated with increased power and output.

21:00 Pediatric patients with systemic Lupus and muscular dystrophy improved with creatine.

21:45 Creatine may enhance the anabolic environment from resistance training.

23:00 Hair loss was indicated in one creatine study, but the cause was not explored.
