Arnold Schwarzenegger is partnering with Momentous to launch The Arnold Stack, a simplified three product lineup built around what he describes as his daily non negotiables: protein, creatine, and vitamin D3.
What Is in The Arnold Stack
The stack includes:
Protein, offered through Momentous in whey isolate and plant options
Creatine monohydrate
Vitamin D3
The positioning is intentionally simple. This is not a 12 bottle supplement cabinet. It is the basics for consistency.
Why This Partnership Matters
Momentous has built a reputation around performance and credibility, including NSF certification across much of its lineup. Arnold brings mass cultural authority in training and longevity. Together, they are packaging the fundamentals as the message, not the optimization rabbit hole.
Final Take
The Arnold Stack is built for people who want a clear starting point and a repeatable daily routine. It is a reminder that the most effective “stack” for most people is still consistency with the basics.
