Collagen is a structural protein abundant in skin, bone, cartilage, tendons, and other connective tissues. As we age, natural collagen production declines, which can show up as wrinkles, sagging skin, brittle nails, slower joint recovery, etc. Supplementing collagen is thought to help by providing amino acids (like glycine, proline, hydroxyproline) needed for building and repairing collagen in the body.
There are different types and sources of collagen, different forms (peptides, hydrolyzed, etc.), and added ingredients. These all affect how you absorb it, what it may be especially good for, how it tastes (or doesn’t), and other side benefits.
The Three Products Compared
Here are the three GLW products we’re looking at:
Product | Key Features / Ingredients | Claimed Benefits |
Hydrolyzed Collagen Peptides (Sera & Mattina) | Types I & III collagen, from grass-fed, pasture-raised bovine; hormone-free, non-GMO; includes hyaluronic acid; enzymatically broken down (peptides) for better absorption.

Bovine vs. Marine vs. Marine + Pearl
Here are some of the differences and trade-offs to keep in mind:
Which Product Might Be Best for You?
Here are some suggestions depending on your goals / lifestyle:
- You want overall collagen boost for joints + skin + hair, and you prefer animal sources like beef → The Hydrolyzed Collagen Peptides bovine option is solid. Especially good if you also care about gut/hormone support and want something you can mix into many different things.
- You prefer marine collagen / fish-based sources or want something very light, easy to take, travel-friendly → The Premium Marine Collagen Packets are great. Single servings make it easy, especially if your schedule is busy or you don’t want to measure scoops.
- You want more of a beauty-focused, luxe product with extra minerals, antioxidants, and care for skin tone, hair strength, nails → Then Holi (Mane) may offer more. The pearl powder and trace minerals plus the marine collagen may yield that “glow / shine” effect, though always with realistic expectations (collagen helps, but it’s not a miracle overnight).
- Budget matters: Marine sources often cost more; added ingredients cost more; so if price per gram is a factor, the simpler collagen powder (bovine or pure marine) might offer good value.
- Dietary restrictions or allergies: If you have fish allergies, avoid marine options; if you avoid beef or want non-bovine, go marine. Also check for certifications if that matters (non-GMO, wild-caught, etc.).
Tips for Getting the Best Results from Collagen
- Use consistently: benefits (skin, joints, nails) tend to appear over a few weeks to a couple of months of daily use.
- Combine with Vitamin C: Vitamin C is important for collagen synthesis. Taking collagen supplements while ensuring adequate Vitamin C from diet or supplement can help.
- Hydration and diet: Collagen works best if your skin/hair/nails “raw material” from other nutrients is adequate: protein, healthy fats, minerals.
- Quality matters: Check for purity, source (wild-caught, grass-fed), avoid unnecessary fillers or additives.
- Consider form: Powders vs. single-serve vs. blends with extras. Choose what you’ll stick with.
All three products are good quality options; the best one depends on your needs:
- For a strong, all-rounder collagen supplement, especially to support joints, skin, nails, hair, Hydrolyzed Collagen Peptides (bovine) is a great pick.
- If you lean marine sources, want something easy and clean, the Premium Marine Collagen Packets are excellent.
- If your goal is beauty enhancement—skin tone, hair shine, nail strength—with a luxe touch, Holi (Mane) offers extra mineral and antioxidant benefits.
