Arnold Schwarzenegger is a name synonymous with bodybuilding and fitness. Even at 78, he remains dedicated to his health and wellness. On February 1, 2026, he shared insights into the three most critical supplements that play a role in maintaining his strength and vitality. This article distills his advice, giving you practical tips to enhance your own fitness journey.
In his prime, Schwarzenegger secured seven Mr. Olympia titles, besting legends like Franco Columbu, Sergio Oliva, and Tom Platz. While decades have passed since he graced the competition stage, intensifying long-term health has become a new mission for him. This pursuit led him to identify the three key science-backed supplements that contribute to his sustained fitness.
“Three supplements that earn their place. I want to start here, with what works because that’s more useful (and a lot shorter) than leading with a list of what doesn’t.”
Arnold Schwarzenegger’s Top 3 Supplements
In a recent newsletter, Schwarzenegger outlined his top three essential supplements for optimal health and fitness.
1. Protein
Leading his list is protein. Schwarzenegger emphasizes its importance beyond muscle building.
“It’s easy to think about protein as only for building muscle. But it’s so much more. Protein is the building block of every cell in your body. It’s essential for enzymes, tissues, and hormones, forming the basis for overall health.”
Research indicates that protein supplementation can lead to substantial increases in strength, lean mass, and muscle fiber size. Schwarzenegger references a large meta-analysis that found an effective daily intake of approximately 1.6 to 2.2 grams of protein per kilogram of body weight, or about 0.7 to 1 gram per pound.
“If you prefer whole food sources, that’s perfectly fine. But if you’re falling short, adding protein powder can help you meet your daily needs.”
2. Creatine Monohydrate
Next on the list is creatine monohydrate, renowned for its performance-enhancing properties.
“I recommend creatine to more people than any other supplement. The consistent research supporting its effectiveness is impressive.”
He cites studies demonstrating that creatine can significantly boost both body mass and strength in individuals engaging in resistance training. Schwarzenegger suggests that a daily dosage of five grams is sufficient for most individuals, but higher amounts may offer additional cognitive benefits.
“Stick to creatine monohydrate; there’s no need for fancy variations. It’s the most researched form and has proven efficacy.”
3. Vitamin D
Finally, Schwarzenegger underscores the necessity of Vitamin D, noting a high prevalence of deficiency among the global population.
“An estimated 35-50% of people are low on Vitamin D, with higher rates in those living in northern regions or spending a lot of time indoors. For this large group, supplementation is essential.”
He recommends starting with a daily dose of 1,000 to 3,000 IUs for optimal benefits.
“Get tested for Vitamin D levels. If they’re below 30 ng/mL, consider supplementation or focus on sun exposure and fatty fish.”
Arnold Schwarzenegger’s commitment to health and fitness continues to inspire both enthusiasts and novice athletes. He believes that if you’re considering supplements, these three have the strongest scientific backing and can genuinely enhance your health.
Conclusion: Incorporating these supplements into your routine, combined with a solid diet and exercise plan, can contribute to your overall well-being. Remember to consult a healthcare professional before making significant changes to your supplement regimen. Staying informed and following trusted advice can empower your fitness journey.
