Grass-Fed Collagen Peptides Powder (Chocolate)
Grass-Fed Collagen Peptides Powder (Chocolate)
20g Collagen.
Every System Supported.
Your body's most abundant structural protein — delivered in its most bioavailable form. Each serving provides 20g of hydrolyzed grass-fed collagen peptides to support your joints, skin, muscle, and connective tissue from the inside out.
28 servings at 1 scoop · 14 servings at 2 scoops · 378g net weight
- ✓ 10g or 20g per serving — you choose — start with 1 scoop (10g) for daily maintenance, scale to 2 scoops (20g) for higher-demand goals like gut health or body composition
- ✓ Grass-fed bovine source — no hormones, no antibiotics, richer nutrient profile than grain-fed alternatives
- ✓ 9–18g protein per serving — 9g at 1 scoop, 18g at 2 scoops, supporting muscle maintenance and satiety alongside collagen's structural benefits
- ✓ Rich chocolate flavor — sweetened with stevia, mixes clean into coffee, smoothies, or water
- ✓ Physician-formulated — developed by a board-certified peripheral nerve and reconstructive surgeon
One Protein. Six Systems.
Collagen makes up roughly 30% of your body's total protein — it's the structural backbone of your skin, joints, bones, muscles, gut, and cardiovascular system. After age 25, your body produces less of it every year.
Skin, Hair & Nails
Hydrolyzed collagen peptides have been shown in multiple RCTs to improve skin hydration, elasticity, and wrinkle depth — with results beginning as early as 8 weeks. Studies also support improvements in nail strength and hair density.
26 RCTs · Meta-analysis 2023Joints & Mobility
A systematic review of 36 RCTs found that type I collagen hydrolysate supports joint comfort, reduces stiffness, and improves mobility scores — particularly in individuals with osteoarthritis. Bovine collagen was effective at just 2.5g/day.
36 RCTs · Systematic review 2025Muscle & Body Composition
Combined with resistance training, collagen peptides have been shown to increase fat-free mass, improve muscle strength, and reduce body fat — especially in older adults. Benefits on body fat have been observed even without changes in exercise.
Placebo-controlled RCT 2023Bone Mineral Density
Meta-analyses show that collagen peptide supplementation — especially combined with calcium and vitamin D — significantly increases bone mineral density at the lumbar spine and femoral neck. Important for postmenopausal bone health.
Meta-analysis 2025 · 12-month RCTCardiovascular Health
A meta-analysis of 12 RCTs found that collagen supplementation significantly reduced LDL cholesterol and systolic blood pressure. Mechanistically, collagen peptides may inhibit ACE activity and support arterial flexibility.
12 RCTs · Meta-analysisGut & Digestive Health
Collagen's glycine and glutamine content supports gut lining integrity and tight junction proteins. In one clinical study, 93% of participants reported reduced bloating and improved bowel habits — with benefits appearing within just a few days.

Full Amino Acid Profile
Per serving (27g) — sourced entirely from hydrolyzed bovine collagen peptides
Glycine and proline are the key structural amino acids in collagen and central to gut lining integrity, tissue repair, and sleep quality via glycine's inhibitory neurotransmitter effects.
Simple to Use. Easy to Stack.
Two scoops is all it takes. Mix it into anything warm or cold — no grittiness, no aftertaste, just smooth chocolate flavor with 20g of collagen working in the background.
Measure
Add 2 scoops (27g) to a shaker cup or blender. One serving delivers 20g collagen + 18g protein.
Mix
Add 8–10 oz of your favorite beverage — hot coffee, cold almond milk, or water all work beautifully.
Drink
Enjoy daily. Consistency is what drives results — most studies show meaningful changes at 8–12 weeks.
Pro Tip
For joint support, take 30–45 minutes before exercise. For sleep support, mix with warm milk 1 hour before bed (glycine supports relaxation).

Collagen peptides are heat-stable and flavorless in most recipes. The chocolate version adds a rich cocoa note.

The Research Behind the Formula
This isn't a trendy ingredient — collagen is one of the most-studied supplements in the world, with a deep body of randomized controlled trials supporting its efficacy across multiple organ systems.
The research-validated dose for most benefits falls between 5g and 20g per day. This formula is designed to flex with your goals — start at 1 scoop (10g) for skin, hair, and daily maintenance, or use the full 2-scoop serving (20g) for gut health, body composition, and higher-demand protocols.

Not All Collagen Is Created Equal
Grass-fed bovine collagen isn't just marketing language. Pasture-raised cattle produce collagen with a distinct nutritional profile — higher in key nutrients, completely free from synthetic hormones and routine antibiotics.
| Attribute | Conventional / Grain-Fed | Dr. Fitz Grass-Fed ✓ |
|---|---|---|
| Collagen content | Standard | Higher concentration |
| Omega-3 fatty acids | Lower | Higher levels |
| Conjugated linoleic acid (CLA) | Lower | Higher |
| Antioxidants (glutathione, vit. A/E precursors) | Lower | Higher |
| Phytochemicals (polyphenols, tocopherols) | Lower | Higher |
| Antibiotics | Commonly used | None ✓ |
| Synthetic growth hormones | Commonly used | None ✓ |
Compositional differences are inferred from peer-reviewed comparisons of grass-fed vs. grain-fed bovine tissue nutrient density. Head-to-head clinical trials comparing grass-fed vs. grain-fed collagen efficacy are still emerging.
