Today I’m talking with registered Dietitian  Lindsey Janeiro all about collagen. Collagen powder is the most popular supplement on social media with people putting it in everything from coffee to protein snack bites. So I’m talking to an expert to ask everything you want to know – should you take it? What are the benefits? will it make me run faster? lose weight? look pretty? get me friends? fill the hole in my heart???


If you’re new here … My name is Monica Camiseta Cerezo Osaka and I created Run eat Repeat over 9 years ago to document training for my first full marathon and struggles with my weight. I ran that marathon, eventually lost the weight and the site turned into a terrific community online and now this podcast! thank you for listening!

Now ‘let’s warm up!

Warm Up:

This weekend I’m running the Revel big Bear Marathon.

Thoughts before the race… approaching doom.

I don’t feel ready at all. and that stresses me out.

I used to run a half marathon and full marathon practically every month. I fell off the wagon because I was sad, not inspired and provided up on my goal.

In doing the notes for the warm up and identifying that I’m not ready to run a full marathon – in part because I didn’t train long or hard enough… but also because I got hurt in a non-physical way that really messed me up… makes me feel a bit better about it.

Yes – I could have gotten it together and ran the hell out of other marathons in the last year. yes – I could have trained harder. yes – I could have gotten in the best shape of my life!!

But I didn’t… so I start here.

This is where I am and I’m moving forward from this spot. focusing on where I was – faster, fitter, thinner… doesn’t help where I am.

I’m not being directly up reckless with my health – turns out I did run 2  -18 mile long runs! – which is all I did for m first marathon (let’s not talk about how I hated myself after that race tho).

And the only way I will get back to running marathon distance is by running a marathon, getting my ass handed to me and getting back on track.

So this weekend my marathon goals are:

A. Run a sub-4 hour marathon

B. finish the marathon strong – run smart, pay attention to fuel and how I feel to learn from it

C. Finish.

D. Not die.

And I’m running with my 1 friend!! So I’m really excited about that!!

Don’t forget – there are a lot of races coming up!!

Here’s some info from Lindsey Janiero RD via Nutrition to Fit:

Collagen 101 – what is it?

Collagen is the most plentiful protein in your body, found in skin, muscles, tendons, bones, ligaments, and even teeth, blood vessels, and corneas. Collagen has many roles, from assisting give your skin elasticity to providing strength in your bones.

What’s in collagen made from?

Hydrolyzed collagen peptides are made by processing animal cartilage, hides, and bones. This can be from cows, pork, chicken, or other animals and may include one source (i.e. bovine hides) or multiple (hides and cartilage). They can also be sourced from marine sources, like shellfish, fish skins, or cartilage from fish or sharks.

What are the benefits?

Collagen lovers claim collagen benefits/ collagen peptide benefits for anything from improved hair, nails, and skin, to joint health, digestive health, and other various medical conditions.

Note: Dietary supplements are not regulated by the FDA in the same way our conventional food supply is regulated, which means supplement business are expected to evaluate the safety and labeling of their products before marketing to ensure they meet all demands of DSHEA and FDA guidelines (6).

Are there specific benefits for athletes?

Research is suggesting that collagen may reduce and prevent joint pain and bone density loss (9). One 24-week study looked at hydrolyzed collagen as a dietary supplement to help athletes with activity-related joint pain, noting possible benefits of collagen supporting joint health, minimizing joint pain that could inhibit athletic performance, and possibly reduce the risk of joint deterioration in certain individuals (10).
