Baar recommends a simple selection-and-timing rule for collagen support. Choose hydrolyzed collagen made from animal skin, such as bovine hide or fish skin, rather than focusing on whether the label says type I or III or advertises a special peptide. Digestion reduces collagen to amino acids, especially glycine and proline, so the original collagen type is not the key feature. Take it with vitamin C, which is required for collagen synthesis. When targeting a tendon, ligament, or cartilage site with limited blood supply, consume the mixture roughly 30 to 60 minutes before loading. Stretching or compressing the matrix helps fluid—and its amino acids—enter the tissue. Baar repeatedly emphasizes that nutrition contributes only a small fraction of adaptation compared with the loading stimulus itself.
Origin
Baar developed the recommendation through collagen-synthesis studies, including work during a sabbatical with Luke van Loon, and his earlier gelatin-plus-vitamin-C research.
Core principles
- 01Collagen supplements provide amino-acid building blocks rather than intact tendon collagen
- 02Skin sources avoid the heavy-metal concern Baar raises about mammalian bones
- 03Vitamin C is an essential cofactor for collagen synthesis
- 04Loading helps poorly vascularized tissue exchange fluid and receive nutrients
- 05Supplementation is a small adjunct to the loading stimulus
How to run it
- 1
Check the collagen source
Select a product whose ingredient identifies a skin source such as bovine hide or fish skin.
Pro tip The collagen type on the label matters less than the source because digestion breaks it into amino acids.
Watch out Baar raises a heavy-metal concern with collagen-rich broth made from mammalian bones.
- 2
Use a supported dose
Use at least five grams of hydrolyzed collagen, the amount Baar says increased muscle connective-tissue protein synthesis when blended with whey in a study.
Pro tip Higher doses have also been studied, but the transcript does not establish one universal optimum.
Watch out Do not reduce the dose merely because a product claims a uniquely active peptide.
- 3
Add vitamin C
Take vitamin C with the collagen so the cofactor needed to synthesize and export collagen is available.
Pro tip The goal is sufficient availability during increased synthesis, not treating ordinary intake as deficiency.
Watch out The episode does not establish a universal vitamin C dose recommendation from Baar.
- 4
Time the intake
When targeting a specific poorly vascularized tissue, consume the collagen and vitamin C about 30 minutes to one hour before loading.
Pro tip Taking it afterward is still acceptable when pre-loading timing is impractical.
Watch out Timing is an optimization, not a replacement for the exercise stimulus.
- 5
Load the target tissue
Perform the appropriate controlled loading exercise as amino-acid levels rise so matrix fluid exchange can deliver nutrients to the site.
Pro tip Match the movement to the tendon or ligament you are trying to reach.
Watch out Collagen without loading is unlikely to drive most of the desired adaptation.
In the wild
Baar says that taking collagen 30 minutes to an hour before loading a specific site lets amino acids peak as the matrix is stretched or compressed and draws in surrounding fluid.
→ More of the consumed building blocks may be delivered to the targeted rotator cuff during loading.
Baar describes work with Luke van Loon in which whey blended with five grams of hydrolyzed collagen increased muscle connective-tissue protein synthesis.
→ The study demonstrated that connective-tissue protein synthesis responds to diet.
Common mistakes
Buying collagen by type number
Baar says type I versus type III does not matter after digestion breaks the supplement into building blocks.
Paying for a magic peptide claim
He reports that companies' claimed special peptides did not justify using a lower dose in his testing.
Expecting food to replace force
Baar estimates that loading explains the overwhelming majority of muscle and connective-tissue adaptation.
Is it for you?
Best for
People already using an appropriate loading program who want a modest nutritional adjunct for a targeted tendon, ligament, or cartilage site.
Not ideal for
People expecting collagen alone to repair tissue without loading or those who need individualized medical or nutritional advice.
From the transcript
“It doesn't matter if it started from type 1 type 3. You want it from the skin.”
“We recommend taking those things together just because the vitamin C is absolutely essential for your body's ability to to synthesize collagen.”
“If you're really trying to target it to one specific spot, take it before, about 30 minutes to an hour before, and then those amino…”
