Creatine won’t magically give you abs. Here’s what it might do

FLORIDA — A lot of creatine experts are sick of the way we talk about creatine. Some are tired of cotton candy-flavoured energy drinks hawking “super creatine” on neon cans, protein bars infused with the supplement, social media posts confusing creatine with steroids.

FLORIDA — A lot of creatine experts are sick of the way we talk about creatine. Some are tired of cotton candy-flavoured energy drinks hawking “super creatine” on neon cans, protein bars infused with the supplement, social media posts confusing creatine with steroids.

Others are tired of the slew of “before and after” TikToks in which trim young men show off bulging muscles after a handful of weeks taking the supplement, or women display rippling abs they attribute only to the powder.

“I don’t know why people make up things about this particular supplement,” said Dr Jose Antonio, an associate professor of health and human performance at Nova Southeastern University in Florida who has studied creatine. The world of creatine is rife with misinformation, he said, despite the large — and growing — body of evidence that the supplement can improve short bursts of athletic performance and enhance muscle mass.

Is the powder a miracle workout supplement, or is the hype overblown? Here’s what to know.

WHAT EVEN IS CREATINE?

Creatine is formed in the body from compounds similar to amino acids, the building blocks of proteins. It serves as a type of fuel for your skeletal muscles, and can promote muscle growth when paired with exercise. It’s produced in the liver and kidneys, but you likely get creatine through your diet, too — red meat, fish and chicken contain it.

Throughout the day, your body naturally replenishes creatine in your muscles, but supplements can help “top up the tank,” said Dr Eric Rawson, a health, nutrition and exercise science professor at Messiah University in Pennsylvania.

Creatine monohydrate — the form of creatine typically found in commercial powders — has been rigorously studied. “There’s probably more data on creatine monohydrate than any other supplement in existence,” Dr Antonio said.

There are more than 20 different formulations of creatine, Dr Rawson said, including creatine hydrochloride and creatyl-l-leucine, but only creatine monohydrate has strong evidence behind it, so he would recommend against consuming another form of the compound.

WHAT ARE THE BENEFITS OF CREATINE?

Creatine has specific, focused benefits for exercisers. The supplement can power you through short bursts of activity, such as lifting a weight or dashing through a short race. If you’re in the middle of a Peloton workout, for instance, you might be able to increase your speed for a sprint, said Dr David Creel, an exercise physiologist and a psychologist and dietitian in the Bariatric and Metabolic Institute at the Cleveland Clinic.

But the effect is usually small. Creatine makes the most sense for certain competitive athletes eager for a split-second advantage, said Dr Samantha Heller, a senior clinical nutritionist at New York University Langone Health. “For your average gymgoer, someone who’s a cyclist, someone who plays soccer on the weekends — they don’t need this,” she said.

Scientists have studied creatine and exercise performance since the early ’90s. A recent review of 35 studies found that creatine supplementation, combined with resistance training, increased lean body mass — the body’s weight, minus fat — by more than two pounds (0.9kg) in adults, regardless of age. The difference is small, but significant, although men reported higher gains than women. Vegetarians and vegans are more likely to have a larger response to the supplements, since they don’t get as much creatine in their diets, Dr Rawson said.

Creatine may provide a small boost in muscle mass, but “whether it’s a two or three  or four per cent gain, no dietary supplements compare to proper training and sleep and nutrition habits,” Dr Rawson said. Still, the increase could have a notable effect on older adults in particular, he said.

“A very, very small improvement in strength could be the difference between a fall and not a fall.”

And emerging research suggests that creatine could have cognitive benefits, potentially enhancing memory and attenuating symptoms of concussions or traumatic brain injuries, although that data is much more limited than studies on creatine and muscular fitness.

ARE THERE SIDE EFFECTS TO CREATINE?

“There really doesn’t appear to be any major hazards to it, which is kind of unique for a supplement,” Dr Creel said.

People who take the supplement, especially in large quantities, might experience some gastrointestinal distress, said Dr Heller. People may also bloat or experience weight gain.

There are some claims floating around social media that creatine causes hair loss, but doctors said there was not significant research to verify that. And you won’t get any kind of high from creatine — it’s not like the jolt of energy you get from downing an espresso, Dr Creel said.

The supplement is popular with teenagers, but there isn’t data on long-term use, especially in people who are still growing, said Dr Pieter Cohen, an associate professor of medicine at the Cambridge Health Alliance, who studies supplements. Out of an abundance of caution, he suggested that teens refrain from using the supplement.

WHAT TO KEEP IN MIND BEFORE TAKING CREATINE

As with any supplement, you should talk to your primary care doctor before you start taking creatine. And just like other dietary supplements you can pull off the shelves, creatine is not tested by the Food and Drug Administration, Dr Cohen said.

That means there’s no guarantee that a powder you’re buying actually contains the amount of creatine it claims, or even any at all. The Department of Defense’s Operation Supplement Safety program recommends four third-party companies that test and evaluate dietary supplements, which you can use to ensure you’re really getting creatine.

You should also stick with the recommended dose, which is usually around three to five grams per day. There isn’t substantial data for how long people can safely take the supplement beyond five years.

It’s also important to come up with specific goals before taking the supplement, Dr Cohen said, and to determine what the pill or powder could actually help you achieve — keeping in mind that it’s not a guaranteed ticket to building muscle.

“People think creatine’s a steroid,” Dr Antonio said. “That’s like saying water is fire.”
