Muscle loss isn’t just for the lazy—it happens when you’re injured, aging, traveling, or even just stuck in meetings all week. And once it starts, it’s harder than you think to reverse.

That’s where HMB steps in. When paired with vitamin D3, it becomes a stealthy tool to help preserve muscle even when your activity levels drop. Prime Powders’ HMB + D3 Capsules are built for those who want to hold onto strength—no matter what life throws at them.

Why Muscle Loss Happens—Even When You’re Not Noticing

Most people don’t think about muscle until it’s gone.

But the truth is, you start losing lean muscle mass as early as your 30s. Add in a week of inactivity—injury, illness, long flights, or deadlines—and the decline speeds up.

Muscle is metabolically expensive for the body to maintain. Without signals to keep it, your body starts breaking it down fast.

The Science of HMB: Muscle Maintenance Mode Activated

HMB (β-Hydroxy β-Methylbutyrate) is a metabolite of the amino acid leucine—and it’s gained attention for its unique ability to support muscle preservation, not just muscle building.

Unlike BCAAs or protein powders, HMB directly influences the body’s muscle protein breakdown processes.

What HMB Does:

• Helps reduce muscle breakdown during inactivity or caloric restriction
• Supports lean muscle mass during aging or bed rest
• Can help preserve strength during recovery periods
• Complements resistance training—but shines during rest phases

Why D3 Isn’t Just About Bones Anymore

Vitamin D3 is often thrown into bone health formulas and forgotten—but that’s a mistake.

Research shows that D3 plays a vital role in muscle function, particularly in older adults or anyone with low sun exposure. It supports muscle contraction, recovery, and strength output.

Even better, it works synergistically with HMB—providing a double-defense for maintaining mass.

Who Needs HMB + D3 the Most? (Hint: It’s Not Just Athletes)

You don’t have to be lifting PRs to benefit from HMB + D3. This stack is made for anyone who wants to protect muscle in less-than-ideal conditions.

Ideal Users Include:

• Adults over 35 looking to prevent age-related muscle decline
• People recovering from surgery or injury
• Frequent travelers or desk-bound professionals
• Individuals in calorie deficits or cutting cycles
• Anyone entering a rest week or light training phase

Preserving muscle isn’t flashy—but it’s one of the smartest things you can do for your long-term vitality.

One Capsule, Smart Routine: Using HMB + D3 Daily

HMB + D3 Capsules by Prime Powders are formulated to make muscle preservation effortless. Just one serving gives you clinically relevant doses of both ingredients—without needing multiple products.

You can take it:

• In the morning to set the tone for recovery
• During travel or downtime
• Alongside a protein shake or post-workout meal
• With creatine or collagen for added synergy

It’s low-maintenance, high-impact—just how your routine should be.

Final Word: Strength Isn’t Just Built—It’s Protected

You work hard to build strength. So why let it slip away every time you hit pause?

HMB + D3 Capsules offer a science-backed way to help preserve the muscle you’ve earned—even when life forces you to rest. It’s not a shortcut—it’s a strategy.
