What's Inside

Hydrolyzed Collagen Peptides

Bovine hide collagen, enzymatically broken down into small, bioavailable peptides that your body can actually absorb and use.

Hydrolyzed Collagen Peptides (Bovine Hide) +

Collagen is the most abundant protein in your body — it's the structural glue that holds your skin, bones, tendons, and connective tissue together. Starting in your mid-20s, your body loses approximately 1% of its collagen per year. By 50, you've lost roughly a quarter of it. Hydrolyzed collagen peptides are enzymatically broken down from their native triple-helix structure into small, easily absorbed peptide chains. Clinical research shows that oral collagen supplementation can improve skin elasticity by up to 25% in 8 weeks and significantly reduce wrinkle depth. The hydrolysis process ensures near-complete absorption in the gut, delivering the key amino acids — glycine, proline, and hydroxyproline — directly to the tissues that need them most.

Why Grass-Fed Matters +

Grass-fed bovine collagen comes from cattle raised on pasture, not feedlots. This matters for two reasons. First, grass-fed cattle produce collagen with a cleaner amino acid profile — free from the hormones, antibiotics, and inflammatory byproducts associated with grain-fed livestock. Second, pasture-raised sourcing reflects a commitment to higher animal welfare standards. We chose bovine hide specifically because it's the richest source of Type I and Type III collagen — the two types most critical for skin, hair, and nail health.

Key Amino Acids in Every Scoop +

Glycine (~33%): Supports skin repair, gut lining integrity, and sleep quality. The most abundant amino acid in collagen and one most people don't get enough of from food alone.

Proline (~12%): Essential for collagen synthesis in the body. Supports skin structure and cardiovascular health.

Hydroxyproline (~10%): Unique to collagen — not found in other proteins. Stabilizes the collagen triple-helix structure and is a direct marker of collagen turnover in the body.

How to Use

Mix. Sip. Glow.

1 Scoop Add one scoop (20g) to your drink of choice. Coffee, smoothie, water — it works in anything.
2 Stir Mix or blend until fully dissolved. Flavorless and odorless — you won't even know it's there.
3 Repeat Take daily for best results. Morning coffee is perfect. Consistency is where the magic happens.

Pro tip: Add it to your morning coffee or matcha — the heat helps it dissolve even faster.

What to Expect

Results Over Time

Collagen is a long game. Here's what consistent daily use actually looks like — no exaggeration, no false promises.

Week 1–2 Your body begins absorbing and distributing collagen peptides. Nails may feel harder. Joints may feel smoother. You're building the foundation.
Week 4–6 Skin starts to feel more hydrated and plump. Hair may feel stronger at the root. Nail growth accelerates. People start noticing.
Week 8–12 Full benefits. Visible improvement in skin elasticity, reduced fine lines, stronger hair and nails, improved joint comfort. This is the payoff.

*Results vary. Consistent daily use recommended for a minimum of 8 weeks.

The Research

Backed by Science

Collagen supplementation is one of the most well-studied areas in dermatological nutrition. Here's what the clinical evidence shows.

25% improvement in skin elasticity Women aged 35–55 who consumed 2.5–5g of hydrolyzed collagen peptides daily showed significant improvement in skin elasticity after just 8 weeks compared to placebo. Proksch et al. — Skin Pharmacology and Physiology, 2014. "Oral Supplementation of Specific Collagen Peptides Has Beneficial Effects on Human Skin Physiology." Double-blind, placebo-controlled study with 69 women.
Significant wrinkle reduction Daily collagen supplementation reduced eye wrinkle volume by 20% after 8 weeks. Procollagen production also increased, indicating the body was manufacturing new collagen. Proksch et al. — Skin Pharmacology and Physiology, 2014. "Oral Intake of Specific Bioactive Collagen Peptides Reduces Skin Wrinkles and Increases Dermal Matrix Synthesis." Placebo-controlled trial with 114 women aged 45–65.
12% increase in nail growth rate Participants taking 2.5g of collagen peptides daily for 24 weeks experienced faster nail growth, decreased breakage frequency, and 42% fewer broken or chipped nails. Hexsel et al. — Journal of Cosmetic Dermatology, 2017. "Oral supplementation with specific bioactive collagen peptides improves nail growth and reduces symptoms of brittle nails." Open-label study with 25 participants.
Questions

Frequently Asked

What type of collagen is this? +

Her Collagen contains Type I and Type III hydrolyzed collagen peptides sourced from grass-fed bovine hide. Types I and III are the most abundant in human skin, hair, nails, bones, and connective tissue — making them the most effective for beauty and joint benefits.

Does it have a taste? +

No. Her Collagen is completely flavorless and odorless. It dissolves fully in hot or cold liquids without changing the taste or texture. Most people add it to their morning coffee, tea, smoothie, or even water and can't tell it's there.

How long until I see results? +

Collagen works from the inside out, so it takes time. Most people notice nail and hair changes within 4–6 weeks. Visible skin improvements — better hydration, firmness, and reduced fine lines — typically show up around weeks 8–12. Consistency is everything.

Can I take this with other supplements? +

Absolutely. Collagen pairs well with vitamin C (which supports collagen synthesis), biotin, and omega-3s. It also stacks perfectly with The Glow Serum for inside-out skin support. There are no known interactions with common supplements.

Why only 14 servings? +

Each scoop delivers a full 20g clinical dose — the amount used in research studies. Many brands use smaller scoops (5–10g) to inflate their serving count. We'd rather give you the dose that actually works and let you subscribe for uninterrupted supply.

Is this keto / paleo / Whole30 friendly? +

Yes to all. One ingredient, zero carbs, zero sugar, zero additives. It fits into virtually any dietary framework. It's also dairy-free and gluten-free.

Is this vegan? +

No. Collagen is an animal protein — there is no vegan source of true collagen. Products marketed as "vegan collagen" are typically collagen boosters containing vitamins and amino acids, not actual collagen peptides. Her Collagen is sourced from grass-fed bovine hide.

What's your return policy? +

We offer a 45-day satisfaction guarantee. If you're not seeing results, contact us and we'll make it right. We stand behind every product we make.

My skin hasn't looked this good in years. The PDRN is the real deal — not another overpriced hyaluronic acid serum. My dermatologist actually asked what I changed.

Hot flashes went from daily to maybe once a week within the first month. Checked the doses against the studies they cite and it's actually formulated properly. Rare for this category.

Completely flavorless. I add it to my morning coffee and can't tell it's there. Hair feels thicker at 4 weeks and nails stopped breaking. One ingredient, no fillers — the way it should be.

Absorbs instantly, no stickiness. My skin is visibly brighter after two weeks. People keep asking if I got a facial. Nope — just this serum, twice a day.

The dual probiotic approach actually makes sense. After 3 years of recurring issues and countless doctor visits, I was skeptical. Within a month everything changed. Finally feel like myself again.

Perimenopause was making me miserable. Night sweats, mood swings, the works. This calmed everything down within 3 weeks. Not a miracle pill but a real noticeable difference.

Only 14 servings but each scoop is a full 20g dose. Most brands give you 5-10g and inflate the serving count. I'd rather have real dosing. Subscribed.

Took about 2 weeks to really see a difference but now I'm hooked. Skin texture is smoother and my foundation goes on like butter. Would be 5 stars if the bottle was bigger.

Been through so many probiotics and this is the first one that actually works where it needs to. The oral + vaginal approach is smart. No more recurring issues since starting this.

I've tried every Korean skincare brand out there. This is the first American brand that actually uses PDRN properly. The peptide complex is smart too. My 42-year-old skin says thank you.

Takes about 3-4 weeks to really kick in so be patient. Once it does though the difference is clear. Hot flashes are way down and I sleep better. Worth the wait.

I put it in my matcha every morning. Zero taste. My hair stylist noticed new growth at my last appointment and asked what I'm taking. That's all the proof I needed.

Was spending $80/month on two separate probiotics. This replaces both for less. And it actually works better because the strains are specifically chosen for vaginal health, not just generic gut stuff.
