Field Notes

Grass-Fed Collagen, Without the Hype

Collagen is the most abundant protein in your body — the scaffolding behind joints, bones, skin, and the gut lining — and your production of it declines steadily from your mid-twenties on. That much is settled biology. What a scoop of collagen powder can do about it is a fairer question, and the collagen aisle isn’t famous for answering it honestly. So here’s the field guide: what the research actually supports, what it doesn’t yet, and how we source ours — grass-fed, pasture-raised cattle and labels short enough to read out loud.

What the Evidence Actually Supports

Ranked by the strength of the research, not the size of the promise.

  1. Joints. The strongest case. A 2024 analysis of 35 randomized trials covering 3,165 patients found small-to-moderate improvements in joint pain and function, with minimal side effects. The typical protocol: 10–15g of collagen daily for at least 12 weeks.
  2. Bones. In a year-long trial, postmenopausal women taking 5g of collagen peptides daily increased bone mineral density at the spine and hip — and the gains held up in a four-year follow-up.
  3. Skin, honestly. Plenty of trials report better hydration and elasticity — but most were industry-funded, and the most rigorous independent analysis found no significant effect. Promising, not proven. A brand telling you otherwise is reading half the literature.
  4. Gut and sleep. About a third of collagen is glycine — the fuel for the cells lining your gut, and an amino acid that improved sleep quality in controlled studies at roughly 3g before bed. Earlier-stage evidence, but it’s why collagen fits a nightly routine.

What to Look For on a Collagen Label

  • A named animal source. “Collagen peptides” alone tells you nothing about how the animal was raised. Ours comes from grass-fed, pasture-raised cattle.
  • Types that match your goal. Types I and III for skin and bone, Type II for cartilage. Bones and connective tissue supply all three; hide-only peptides are mostly Type I.
  • Nothing it doesn’t need. Collagen is nearly tasteless on its own. Gums, fillers, and artificial sweeteners are a choice, not a necessity.
  • An honest protein count. Collagen is protein, but not a complete one — it’s low in leucine, the amino acid that triggers muscle building. Count it toward joints and connective tissue, not as a swap for your protein powder.

Choose Your Collagen

  • Grass-Fed Bone Broth Collagen + Turmeric — a standardized 16g of grass-fed collagen per scoop from slow-simmered beef bones, with turmeric root for curcumin. Four ingredients. Drinks warm like broth or mixes cold.
  • Protein+ Multi-Collagen — 20g of real-food protein plus collagen from four sources — grass-fed beef, wild-caught marine, chicken broth, and eggshell — at 90 calories. The one-scoop answer to “protein or collagen?”
  • Carnivore Complete — protein with five grass-fed organs, tallow, and bone broth in one scoop. Closer to a meal than a supplement, with collagen along for the ride.
Straight Answers

Frequently Asked Questions

What does collagen actually do?

Collagen is the most abundant protein in the body — the structural scaffolding of joints, bones, skin, tendons, and the gut lining. Your natural production declines from your mid-twenties onward, which is why supplemental collagen is most often taken for joint comfort, bone density, and connective tissue support.

Does collagen supplementation actually work?

It depends on what you're taking it for. Joints have the strongest evidence: a 2024 analysis of 35 randomized trials covering 3,165 patients found small-to-moderate improvements in pain and function. Bone density is well supported too, with postmenopausal women gaining spine and hip density on 5g daily over a year. Skin is the contested one — many positive trials exist, but the most rigorous independent analysis found no significant effect, so we won't oversell it.

Which Paleo Pro collagen product should I choose?

Choose Grass-Fed Bone Broth Collagen + Turmeric if you want collagen on its own — a standardized 16g per scoop from slow-simmered beef bones, drinkable hot or cold. Choose Protein+ Multi-Collagen if you want protein and collagen in one scoop: 20g of real-food protein with collagen from four sources at 90 calories. Carnivore Complete includes bone broth alongside protein, organs, and tallow if you want the whole-animal approach.

How much collagen should I take per day?

Follow the research protocols. Joint studies typically used 10 to 15 grams of collagen daily for at least 12 weeks. Bone density trials used 5 grams daily over 12 months. Skin studies ran 2.5 to 10 grams for 8 to 12 weeks. Across all of them, consistency over several weeks mattered more than any single large dose.

What is the difference between bone broth collagen and collagen peptides?

Bone broth collagen comes from simmering bones and connective tissue, so it carries collagen types I, II, and III along with minerals and other compounds from cartilage. Collagen peptides are usually made from hide, are hydrolyzed into smaller fragments for easier absorption, and are primarily type I. Bone broth gives you a broader whole-food profile; peptides give you a more concentrated, standardized single type.

Is collagen a complete protein?

No, and any brand claiming otherwise is stretching it. Collagen is low in leucine, the amino acid that triggers muscle protein synthesis, so it should not replace your regular protein powder for building muscle. Count it toward joints, bones, skin, and connective tissue instead — or use Protein+ Multi-Collagen, which pairs collagen with a complete protein base.

Is your collagen grass-fed?

Yes. Our beef collagen comes from grass-fed, pasture-raised cattle raised without added hormones or antibiotics. The bone broth collagen has a four-ingredient label — beef collagen, turmeric root, natural flavors, and monk fruit — with no gums, fillers, or chemical preservatives.
