“I’ve tried a lot of supplements over the years. Momentous is the one that earned my trust because they always lead with transparency and quality.”
Three daily non-negotiables for lifelong strength. Creatine to support strength and muscle. Whey protein to support recovery and consistency. Vitamin D3 to support bones, immunity, and long-term resilience. This isn’t about optimization. It’s about showing up — every day — for decades. This is how strength lasts.
