Introduction
Most people think about collagen for skin health and joint support, but collagen does more than that. New research shows it may also help with energy and metabolism, especially as we get older. Since our natural collagen production starts to drop in our mid-20s, this can affect our muscle mass, how our body uses fat, and overall vitality (1). In this article, we’ll look at how collagen peptides (including hydrolyzed marine collagen) can support energy levels and a healthy metabolism in adults. We’ll also explore how liquid collagen supplements - like Lemon & Co.’s Lemon Infused Collagen Elixir - fit into a balanced routine for both women and men.
Collagen Decline and Why It Matters for Metabolism
Our body’s collagen levels generally peak in our mid-20s, then gradually decrease (2). That drop can contribute to:
- Reduced muscle mass
- Joint stiffness
- Slower metabolism
All these factors can lower our energy and vitality as we age. Boosting collagen intake - through diet or supplements - may help offset these changes and keep you feeling more energetic.
Collagen content tends to peak in the mid-20s and then declines steadily with age (2). This age-related collagen loss can contribute to reduced muscle mass, joint issues, and slower metabolism. Supporting collagen levels through diet or supplements may help mitigate these changes and maintain energy and vitality in later years.
How Collagen Impacts Metabolism and Energy
Collagen is best known for its role in building and supporting our skin, bones, cartilage, and muscles. However, it also has an indirect effect on energy production and metabolism. Here’s how:
-
Rich Amino Acid Profile
Collagen is full of amino acids like glycine, proline, and hydroxyproline.
Altogether, these amino acids can help your cells produce and use energy more efficiently.
-
Helping Maintain Muscle
Muscle tissue burns more calories at rest than fat, which boosts your overall metabolism (6). As we get older, we naturally lose muscle mass (sarcopenia). Studies show collagen supplements can help preserve or even increase muscle when combined with exercise (7). For instance, in one study, older men taking collagen peptides and doing resistance training gained more muscle and lost more fat compared to men who just exercised (8). Having more muscle helps raise your resting metabolic rate (9).
Collagen Decline After 25 and Its Effect on Metabolism
Collagen production starts slowing down in the late 20s. In one study, the amount of collagen in skin peaked in people aged 25-34, then dropped by about 25% over the next 40 years (10). That loss can lead to more than wrinkles: it can affect your overall metabolic health, too. Less collagen can weaken connective tissues and reduce muscle support, making it harder to stay active and keep your energy up.
By age 30 and beyond, many people notice they tire more easily and find it tougher to maintain a healthy weight. While hormones and lifestyle changes are partly to blame, dropping collagen levels in the body also play a role. Research suggests that taking collagen peptides can help support metabolism in older adults. In a 2023 trial, participants over 50 who took 15 grams of collagen peptides for 12 weeks lost body fat (especially belly fat) while holding on to muscle, while the placebo group gained fat (11, 12). Another review found that collagen, especially combined with exercise, helped participants lose fat, gain strength, and reduce joint pain (13, 14).
Collagen Peptides for Muscle Energy and Recovery
One of collagen’s standout benefits is helping muscles repair themselves after exercise. Intense workouts cause tiny tears in muscle fibers, which must be fixed for muscles to grow. Collagen’s amino acids, such as proline and glycine, play an important part in repairing these tissues (15).
A 2024 review highlighted how oral hydrolyzed collagen peptides can boost muscle health and performance by helping reduce muscle damage after workouts (16). In several studies, athletes taking collagen reported less soreness and recovered faster than athletes who didn’t (17). As a result, staying active feels easier and more energizing. It’s worth noting that collagen doesn’t replace other good protein sources - rather, it complements them. In older adults, combining collagen with resistance training improved muscle strength and lean mass more effectively than training alone (18), likely because collagen’s unique amino acids stimulate the muscle’s support structures (19).
Why Hydrolyzed and Marine Collagen Are Easy to Absorb
“Hydrolyzed collagen” or “collagen peptides” refers to collagen broken down into smaller pieces. This makes it easier for your body to digest and absorb. Research shows these low molecular weight peptides (around 2,000 - 5,000 Daltons) get absorbed effectively and stay in the bloodstream long enough to assist in tissue repair (20, 21).
Marine collagen (from fish) is especially popular for its purity and high type I collagen content - type I is the main type in skin and bone. Studies comparing collagen sources found that fish collagen often leads to higher levels of collagen peptides in the blood compared to similar bovine (cow) collagen (22). Marine collagen is also unlikely to come with antibiotics or hormones sometimes used in livestock. Ultimately, the “best” collagen can depend on personal preference or dietary needs, as both marine and bovine sources have high bioavailability when properly hydrolyzed.
Liquid Collagen Supplements: Convenience and Added Nutrients
Liquid collagen has become a popular choice, especially among those who want a quick, hassle-free supplement. While liquids and powders generally provide the same type of collagen peptides, pre-mixed drinks can include extra nutrients like vitamin C or antioxidants. Vitamin C is particularly important because it’s needed for your body to build and stabilize collagen (23).
A typical collagen drink might contain 5-10 grams of protein in a small serving, which can help support muscle health, keep you feeling fuller, and contribute to a healthier metabolism. Liquid collagen is also portable - great for people with busy schedules.
Lemon & Co.’s Lemon Infused Collagen Elixir: A Modern Twist
A prime example of a liquid collagen product is Lemon & Co.’s Lemon Infused Collagen Elixir, which combines wild-caught marine collagen peptides with vitamin C-rich organic lemons. This carefully designed formula is sugar-free and has no preservatives. Each serving delivers a dose of marine collagen (known for high absorption and type I content) plus natural vitamin C from lemon juice, helping your body effectively use those peptides (24, 25).
Because it’s a liquid packet, you can easily mix it with water - no fuss or measuring. By providing high-quality marine collagen and vitamin C in a refreshing lemon flavor, this elixir targets multiple areas:
- Maintaining muscle, bones, and joints
- Supporting metabolism by keeping you active
- Helping your body build collagen more efficiently
Over time, many people notice improved recovery from exercise, less joint stiffness, and a general boost in everyday energy. Keep in mind that collagen works best as part of a balanced lifestyle that includes nutritious meals, regular exercise, and good sleep.
Conclusion: Energizing Your Metabolism with Collagen
Collagen is more than just a skincare trend. It forms the structural “scaffolding” for our bones, muscles, and connective tissues. By helping you keep muscles strong and joints moving comfortably, collagen can support a healthy metabolism and higher energy levels. Studies show collagen supplements (especially hydrolyzed versions from marine or bovine sources) can help with muscle maintenance, fat loss, and quicker workout recovery (26, 27).
If you’re over 30 and feeling a slowdown, adding a collagen supplement to your routine may help you stay more active and energized. Whether you choose a powder or a liquid collagen drink, the key is consistent daily use along with a balanced diet and regular exercise. Collagen won’t magically melt pounds away, but it can be a powerful ally in overall metabolic health and vitality as you age.
