Bodybuilding legend Arnold Schwarzenegger is sharing more insight into the power of creatine. In Arnold’s Pump Club newsletter from June 16, 2026, he discussed whether creatine provides greater benefits for beginner versus experienced lifters.
Former seven-time Mr. Olympia Arnold Schwarzenegger continues to help fans find new, effective strategies for building muscle and burning fat. At 78, long-lasting health has also become a top priority, prompting Schwarzenegger to eat clean and take supplements.
Creatine can enhance workout performance, aid recovery, and help build muscle. Schwarzenegger has shot down myths around creatine in the past, but is now breaking down how it impacts lifters regardless of their experience level.
Arnold Schwarzenegger Discusses Whether Creatine Is Better at Helping New vs Experienced Lifters
In the newsletter, Schwarzenegger prefaced the discussion by stressing that supplements aren’t an absolute necessity:
“There’s a belief that supplements are something you earn. Put in a few years, hit a wall, and then supplements can help spark more progress. Beginners, the logic goes, grow fast enough already.
There’s a lot of truth to the claim. You don’t need most supplements when you’re starting out (or arguably any at all). But a new analysis specifically tested whether beginners and advanced lifters see different results with creatine.”
According to Schwarzenegger, research suggests that beginners and seasoned lifters build muscle similarly while taking creatine.
“Scientists found that creatine helps beginners and seasoned lifters build muscle similarly, so your experience level doesn’t determine whether it works for you.
“Researchers pooled 61 controlled trials, most of them double-blind and placebo-controlled, then sorted everyone by training history. Across the whole group, people taking creatine alongside resistance training gained about 1.4 kg of fat-free mass more than those on placebo, with no change in fat mass or body-fat percentage.”
He explained that over time, creatine impacts energy production and can help lifters recover between intense workouts.
“Creatine tops off your muscles’ fast-energy system, so you can grind out an extra rep and recover faster between hard sessions. Over weeks, those small wins add up to more lean tissue. The energy and hydration benefits don’t care how long you’ve trained.”
Overall, he emphasized that training history does not influence the benefits of creatine.
“Your training history won’t decide whether creatine works. Beginner or fifteen years under the bar, both groups beat placebo. But just because experience isn’t a variable, that doesn’t mean all creatine delivers the results you want.”
One thing those 61 trials controlled for that your kitchen counter doesn’t: whether the creatine was actually creatine.”
Moreover, Schwarzenegger warned that finding a reputable source of creatine is most important, as many products are packed with fillers.
“In a clinical trial, the powder gets verified before anyone swallows it. The tub off a shelf gets no such promise. Supplements aren’t approved before they’re sold, and independent testing keeps turning up products that don’t match their labels, are underdosed, are cut with fillers, or carry contaminants from cheap manufacturing.”
“You can do everything right, every day, paired with lifting, and still come up short because what you scooped wasn’t what the label said.”
For optimal results, he recommended sticking with around 3-5 grams per day to help fuel workout performance. A higher dose might be more appropriate if you’re after cognitive benefits.
“If you’re wondering how much to take, research suggests 3 to 5 grams of creatine monohydrate can help power physical performance. For cognitive benefits and to fight mental exhaustion, you likely need 10 grams per day. Pair it with lifting and be patient. It’s not magic, but it will help support your goals.”
Schwarzenegger believes creatine can help anyone, from high-level IFBB Pros to the everyday gym-goer. To ensure quality ingredients, he recommends sticking with third-party-certified products.
