You have probably seen creatine supplements at your local drugstore or supplement store. It’s available in drink mixes, powder, energy bars, and tablets. Athletes and bodybuilders have used creatine supplementation since the 1990s. An estimated 40% to 50% of college and professional athletes use creatine supplements.
The Scientific consensus on the effectiveness versus risk profile of creatine is mixed. Some studies find that it can improve athletic performance on a short-term basis, and there’s essentially no evidence that it helps with endurance sports, like marathon running. In fact, some people’s muscles don’t appear to react to creatine supplementation at all.
Your physician is your best advisor on how to take creatine safely.
Creatine is natural – the human body produces it – but that doesn’t necessarily mean it’s safe to supplement what your body makes naturally. That said, most healthy people can take creatine supplements in moderation without damaging their health. But when people take too much, side effects, in addition to erectile dysfunction, can include
• Anxiety
• Weight gain
• Fatigue
• Diarrhea
• Headache
• Nausea and vomiting
• Rash
• Indigestion
What’s more common medications like acetaminophen (Tylenol), diabetic medications, and diuretics can interact dangerously with creatine. Taking creatine along with stimulants like caffeine can also increase the risk of unpleasant or dangerous side effects. Doctors advise that people who take creatine drink plenty of water and avoid dehydration. And whether or not you experience erectile dysfunction, you should always tell your doctor about creatine or any other supplements or over-the-counter medications you take regularly.
