How do I avoid stomach problems when taking creatine?

Answered by Nikkiey Stott and her guests · Updated

The short answer

Take a low dose and take it with food. Nikkiey explains that creatine's stomach cramps, nausea, diarrhea and bloating tend to show up with large doses or on an empty stomach. Start around five grams a day, increase gradually only if you want to, and mix it into a protein shake or a meal with carbohydrates.

The full answer

Nikkiey explains that creatine's digestive side effects usually come from an osmotic effect: it can pull water into the intestines, which is what causes the diarrhea and discomfort. Some people are simply more sensitive to it than others, so pay attention to how your body responds. She speaks from experience here. On Ep. 192 and Ep. 15 she shares that when she took creatine on an empty stomach, she was cramping for about an hour afterward.

The fix is about how you take it:

  • Start low. The episodes recommend about five grams a day, then increasing gradually over time.
  • Take it with food, ideally a protein shake or something with carbohydrates, which she says helps absorption and minimizes discomfort.
  • Stay hydrated. Nikkiey repeats this throughout her creatine episodes, because creatine pulls water into the muscles.

There is a small difference between episodes on dose. On the podcast she says five grams a day and build gradually. In her video on creatine safety, she gives five to ten grams a day as the typical range, roughly one or two scoops, and adds that you don't have to go up to ten. You can stay at five grams as long as you like.

Her own routine is simple: after her workout, she puts one scoop of creatine into her protein shake, blended with unsweetened almond milk and frozen bananas and strawberries. If your stomach has been rough on creatine, it's probably the timing or the amount, not you. Nikkiey also asks that you check with your doctor before starting creatine, especially if you have any existing kidney concerns.

    Can creatine help with brain fog in perimenopause?

    Nikkiey says it can. Your brain uses creatine for energy the same way your muscles do, and she points to studies showing better memory, processing speed and executive function. She noticed more clarity and energy herself during a stretch of brain fog and fatigue, and calls it directly relevant to perimenopause brain fog.

    Should women in menopause take creatine?

    Nikkiey says creatine can be a smart addition for many women in menopause who want to keep or build muscle and strength. As estrogen drops, the risk of osteoporosis and fractures rises, and she notes creatine is commonly used by older adults for muscle support. She advises checking with your doctor first and staying well hydrated.
