Hydrolyzed Collagen Peptides are the backbone of Sera & Mattina’s product line, and for good reason. Collagen is the most abundant structural protein in the body, giving skin its resilience, cushioning joints and muscles, and providing the building blocks for connective tissue. As we age, natural collagen production declines, leading to dryness, sagging and stiffness. Supplementing with a high-quality collagen peptide can help fill that gap and support youthful vibrancy.
What Makes Hydrolyzed Collagen Special?
Collagen peptides are produced by breaking down the long collagen molecule into smaller fragments. These peptides (typically 2000–3500 Da in size) are water-soluble and easily absorbed through the digestive tract. Clinical research shows that collagen peptides from bovine, porcine and marine sources improve skin quality, joint function and muscle recovery.
Skin hydration and elasticity – Multiple placebo-controlled trials found that women taking 2.5–3 g of collagen peptides daily for 8–12 weeks experienced significant improvements in skin hydration, elasticity and dermal density compared with placebo (Proksch et al., 2014; Bolke et al., 2019). Fine lines and wrinkle depth decreased, and skin felt smoother and more hydrated.
Joint comfort – In a recent double-blind trial, patients with mild knee osteoarthritis who took 3 g/day of low-molecular-weight collagen peptides for 180 days reported less pain and better physical function than those on placebo (Kumar et al., 2025). No serious adverse events were reported.
Muscle recovery – Reviews of sports nutrition literature suggest that collagen supplementation combined with resistance training improves body composition and muscle strength in older adults. Peptides in the 2 000–3 500 Da range show greater bioavailability and may aid recovery from exercise (Jendricke et al., 2019; Zdzieblik et al., 2015).
Sleep support – Collagen is rich in the amino acid glycine, which acts as a calming neurotransmitter. Studies show that 3 g of glycine before bedtime reduces sleep latency and improves subjective sleep quality (Yamadera et al., 2007; Inagawa et al., 2006). This adds a nighttime benefit to your daily scoop of collagen.
Why Choose Sera & Mattina’s Hydrolyzed Collagen Peptides?
Sera & Mattina’s hydrolyzed collagen is sourced from grass-fed bovine hides and hydrolyzed for maximum absorption. It contains no additives or fillers and dissolves easily into hot or cold liquids. One serving provides 20 g of pure collagen peptides, enough to match the dosages used in clinical trials. The neutral flavor makes it easy to add to morning coffee, smoothies, soups or baked goods.
How to Incorporate Collagen Into Your Routine
Daily nourishment: Mix one scoop (20 g) into your beverage of choice every day. Consistency is key; most studies observed benefits after 8–12 weeks of daily use (Proksch et al., 2014).
Pair with vitamin C: Vitamin C is essential for collagen synthesis. Consider adding fresh citrus, berries or a vitamin C-rich supplement to support your body’s natural collagen production.
Evening ritual: Enjoying collagen in the evening supplies glycine, which may promote relaxation and better sleep quality (Inagawa et al., 2006).
Combine with movement: Resistance training amplifies collagen’s benefits for muscles and joints (Jendricke et al., 2019).
The Bottom Line
Hydrolyzed collagen peptides are more than just a beauty supplement. Research shows they support skin hydration and elasticity, reduce joint discomfort, promote muscle recovery and may even contribute to more restful sleep. Sera & Mattina’s Hydrolyzed Collagen Peptides deliver a potent, high-purity serving of these clinically studied peptides, making them an easy addition to your daily wellness routine.
