Walk into any supplement aisle and you’ll probably see the same three products everywhere: protein powder, collagen, and creatine. But what do they actually do — and are they necessary?
As a Registered Dietitian, I always encourage people to focus on the basics first: consistent nutrition, strength training, sleep, hydration, and recovery. Supplements can be helpful tools, but they work best when supporting a strong foundation.
What Is Protein?
Protein is one of the body’s essential macronutrients and is made up of amino acids that help:
• Build and repair muscle
• Support recovery
• Keep you full and satisfied
• Support immune function and overall health
Protein becomes especially important as we age. Beginning around our 30s and 40s, we naturally start to lose muscle mass, strength, and bone density over time, a process that can accelerate during peri- and post-menopause due to hormonal changes. Men experience age-related muscle loss as well, though typically more gradually.
Adequate protein intake, combined with strength training, can help support:
• Muscle maintenance
• Strength and mobility
• Bone health
• Metabolism
• Recovery and healthy aging
Protein needs are often higher for people who:
• Exercise regularly/strength train
• Are peri- or post-menopausal
• Are aging
• Are recovering from injury
• Are trying to lose weight while maintaining muscle
Protein powders can simply be a convenient way to help meet daily needs when intake is low or schedules are busy.
What Is Collagen?
Collagen is actually a type of protein — and the most abundant protein in the body. It’s found in:
• Skin
• Tendons
• Ligaments
• Cartilage
• Bones
Unlike whey or soy protein, collagen is considered an incomplete protein, meaning it does not contain all the essential amino acids needed to effectively support muscle building.
That means collagen should not replace your main protein source.
Collagen may help support:
• Joint health
• Connective tissue
• Tendons and ligaments
• Skin health
Collagen may be beneficial for active adults, aging adults, or people experiencing joint discomfort, but it works best alongside adequate overall protein intake and strength training.
What Is Creatine?
Creatine is a naturally occurring compound stored in muscles that helps produce quick energy during high-intensity exercise.
It’s one of the most researched supplements available and has consistently been shown to support:
• Strength
• Power
• Exercise performance
• Muscle recovery
Scientific evidence suggests creatine supplementation can also help improve cognitive performance, particularly during periods of mental fatigue, sleep deprivation, and in older adults.
Will Creatine Make You Bulky?
One of the biggest misconceptions about creatine is that it will make you “bulky.” For most people, this is simply not true when taken at the recommended dose.
The initial “bulking” some people notice from creatine is temporary and mostly due to water retention within muscle cells — not fat gain. When taken at the recommended dose of 3–5 grams per day, this typically stabilizes within the first few weeks.
Who May Benefit from Creatine?
• People strength training
• Athletes
• Older adults
• Peri- and post-menopausal women
• Vegetarians and vegans
The Bottom Line
As we age, especially during peri- and post- menopause, maintaining muscle becomes increasingly important for long-term health, mobility, metabolism, and quality of life. While supplements like protein, collagen, and creatine can be helpful tools, they work best when paired with consistent nutrition, strength training, sleep, and recovery.
As a Registered Dietitian and coach, I help clients cut through the confusion around nutrition and supplements and create realistic, sustainable, evidence-based plans tailored to their goals and lifestyle.
