Supplements I don't take: collagen

[@nonsensei1]

Dave is the best. So good at de-tangling complicated questions into their counterparts and weighing the evidence. I personally messaged him for some tendonitis advice and he gave very detailed advice and assurance, which I did not expect at all, as he's probably very busy. That meant a whole lot to me. If you are reading this, thank you so much again. Keep making stuff Dave! I decided to and managed to quit vaping e-cigarettes since that discussion as well.

[@HoopersBeta]

Well said! I love the approach and personally loved the story at the end on the wonderful job of rebranding that collagen has done with regard to food waste :) - Jason

[@marcelodias6781]

In the collagen studies (Praet et al 2019; Gregory et al 2017; Jerger et al 2023) they should have included some sort protein placebo (e.g., whey or pea) to account for increase in protein intake. An isocaloric control (apparently maltodextrin seem to be a common choice) without accounting for the protein content is not a good control. Best case scenario they would have 2 controls: a protein based and a maltodextrin based placebo.

[@simonsharpe8772]

I think you missed the key ingredients in the gelatin study which was that it was enriched with vitamin C. as we know from how connective tissue is form in anatomy, tendons are formed from bundles of collagen fibres which are formed of bundles of fibrils which in turn is form from filaments. The fibroblasts as the cells that form the filaments require vitamin c to regrow the filaments, Vitamin C also increases the proliferation rate of fibroblasts. So that's why that study may have got the results it got over the gelatin side. I always recommend people have orange juice or better still orange as fruit for a healthy supplement to get the high dose of vitamin C for tendon health, but like you said there are plenty of other factors that are at play. Rest and over training, is the main cause of injury in my experience.

[@kubawydra7286]

What is your take on creatine? Would absolutely love the episode on that.

[@kutaycelik3196]

I was also wondering the same. Its common supplement that seems to come up in discussions

[@AdamL_18]

creatine have not much debate to have on since its the most studied supplement, research are pretty clear about it. and if you hear anything bad about it, its myths that have been debunked.

[@dkeener13]

Yes. I love the idea for this as a series, creatine is one I'm most interested in. It seems very beneficial in most sports, maybe more nuanced in climbing as strength gains are at least partially offset by weight gains.

[@aaronhauptmann869]

Like he mentions in the video creatine is actually proven effective through evidence based science. It's literally the counterexample he uses against collagen.

[@aaronhauptmann869]

​@@dkeener13 the weight gains in the vast majority of climbers is insignificant if it actually helps you get stronger, especially in the long run. Some people report getting extremely pumped after supplementing creatine, now that is actually a big issue for most climbers. But you might have to try and find out how you respond to know for sure.

[@benhewitt97]

As a cell biologist, this is a fantastic video Dave. Thanks for delving into the data so well, and in such a balanced way. Would be really keen to hear your views on creatine - I have my own, but would be really interested to hear from you based on your experience and knowledge of nutrition!

I am not really interested into supplements but would like to say your videos about feet placements were pivotal in my climbing journey.

[@christophertonkin4949]

Hi Dave. Your videos on nutrition are great. Love the detailed and unbiased approach. Would be great to hear your views on Creatine some time as this is another supplement popular among climbers. In particular it's supposed to help with explosive power, which as an older climber I'm working hard to hold on to.

[@wenlambotomy6231]

Creatine is the most scientifically studied supplement that actually does something. Physical and mental. In short - yes just take it. My only concern in relation specifically to climbing is does it cause your forearms to pump out ….?

[@Hopesfallout]

Creatine won't help you with explosive power, training explosive power will. Creatine might have a marginal effect on training, however, so it's probably worth a shot if you respond well.

[@joefernandez4170]

@christophertonkin4949 i actually asked Dave if he supplemented creatine and he told me that he gets enough of it with his current diet(primarily from red meat i think)

[@Gannicius]

​@Hopesfallout creatine facilitates higher quality training for power and maximal strength. Quality reps are what is important, and creatine can help an athlete achieve more high quality reps (assuming their programming is also good).

[@alexgalays910]

if it's mainly fingers that limit the number of your trainings (e.g "I need to rest 2 days to fully recover my fingers"), I don't find collagen to do anything worthwhile. Maybe worth supplementing if you're vegetarian though.

[@michaelbarker6460]

Wow this felt like it was really well done and thorough. The part that stood out the most is there's no attacking any ideas or anyone, you agreed with points of other views than your own without any issue because you legitimately seem to just agree with those points. Overall it tells me this was made by a mind that's not reactive, can look at all the sides of a topic and simply take the best ideas and positions from all of it and present it in a way that isn't definite truth but what you believe makes the most sense at the current time. Which long story short is a massive breath of fresh air. I'll be watching your videos in the future for sure and will be recommending you to my friends!

Dave - again thank you so much for this crystal clear, authentically motivated inquiry. Can’t fully express how much your trusted voice helps with my clarity on these important and often desperately muddied waters. Obviously I share your lack of certainty but the direction your scepticism points towards STINKS of truth to me! Big thanks!

[@PotatMasterRace]

You probably need many years, perhaps decades, to see any benefits of additional glycine/proline intake. Since you supplement a little more, and your body has to rely less on endogenous synthesis, and since some amino acids like glycine can act akin to mediators of internal processes, maybe there is a long term benefit.

[@biigginger]

Thank you for yet another informative video, Dave! You often speak of eating sufficient high quality protein and the importance of a healthy diet. I'd like to hear your take on general nutrition in a diet that would not require supplementation. Or even a video walking through your own personal diet, what do you eat in an average week, for example.

[@Hopesfallout]

Thank you Dave for keeping things complicated. :D It's funny how you go quite in-depth on some actual studies (the lack of studies in the field makes it a bit more convenient of course ;) and still manage to keep your video shorter than the content of some more "collagen-enthusiastic" creators who seem very concerned about our time and limited ability to understand biochemical processes. I liked that you showed and cited actual papers word for word, too much information gets lost in inaccurate paraphrases these days. As for my own collagen supplementation, I was aware of its esoteric nature, having read and at least partially grasped the meaning of some of your cited studies. But rupturing a biceps tendon makes one desperate I guess. Still, your content serves as a well-needed reality check, thank you for that again!

[@peters616]

You raise very good points but there is a study (with no apparent conflicts) that compared Collagen supplements to just protein supplements and found that Collagen was better for the endpoints studied which was skin healing (not ligament strength). It's a 2019 study which was a randomized double-blind trial with 31 men who had serious burns which found significantly higher healing in the Collagen group as compared to a group taking the same amount of soy protein. Of course, the mechanism may be different in ligaments, but this does tend to show that Collagen isn't just masking the benefits of increased protein.

[@ThatOneHomlessGuy]

Love this Dave! Lots of advertisements for collagen in climbing but not as much research being chucked in with these advertisements has had me skeptical.

[@zacharylaschober]

used to be worthwhile to experiment, but collagen has seemingly more than doubled in cost in this last year. was an easy addition to my morning tea, but now is more expensive than just adding a half scoop of whey into my diet to increase protein content of breakfast.

[@eheath23]

Fantastic video, thanks Dave! I really appreciate your data-driven, nuanced and scientific approach. This may not be a dietary supplement, but I'd be curious to see what you make of skin care products for skin healing and conditioning. There are balms and lotions galore, many of them seem to follow the same marketing models as supplements, and very few of them are developed with any experimental research or understanding of biochemistry. I would also be interested to in your scientific approach to some alternative treatments that are quite popular in climbing circles, such as cupping, chiropractic, and accupuncture rings. I understand the urge to try things out of desperation, but I'm totally unconvinced by other climbers' anecdotal evidence for these interventions. I'd also really appreciate an explanation and how-to video for reading sport science papers, and how you appraise the available evidence on a given subject. Thanks for the time you put into your research and videos, it really shows, and it's extremely useful for so many of us in the climbing community!

[@Hopesfallout]

Oh man, Dave trying to keep a straight face while attempting to find any scientific value in cupping or chiropractic would be hilarious.

Great advice! I just purchased your book after reading this. The most I've ever spent on a book, but after this video, I decided your perspective is worth it. I do a lot of paddle boarding and martial arts training. Repetitive movements in SUP gave me tennis elbows, and fast and furious kicking took a toll on my spine, neck, pelvis, and knees. I supplement with whey for protein, K2, calcium, komatsuna, and natto for bones, chondroitin, VitD fish oils, and glucosamin for joints, creatine and amino acids for muscles but recovery still seemed to be slower than I like. I've been supplementing sufficiently but have only been sleeping an average of 5 hours for the past 2 years. I changed that recently to 7 hours and added lamb legs to my diet, and I'm now able to handle 8 hours a week of SUP together with 20km a week of jogging, and 7 hours a week of spin kicking this way and that way. I'm not getting any younger (43), and I'd like to keep this up as long as possible. That's why I am interested in your book about regulating work and recovery. Thank you!

Most people dont need vitamin or mineral Supplements (especially not a couple of 100s % of the daily need) as they get enough in their diet. Taking high doses (like ag1) for a Long time might Even be harmful (i think it was an increased cancer Risk). Dont believe paid climbing Channels, Even if they claim their content is evidence Based. They are paid to do funny conmercials, they Even delete critical comments. Just Google reviews about Vitamin Supplements and you get plenty of information. Look for papers and Not reviews by influencers. If they Review it, check that they Talk about the effect of these super high doses.

Loved this and your AG1 video. This one might not be as popular, but I'd be curious to hear your thoughts on the typical endurance athlete diet. A lot of us climbers are also interested in trail and mountain running, and carbohydrates are the foundation of endurance nutrition.

How do performance endurance athletes think about these two potentially competing perspectives? Thanks, Dave!

[@felixinfinita3777]

I've been taking collagen peptides for quite some time now. But originally I decided to take it not to increase tendon strength, but for better skin recovery. Skin was a major letdown for me. My skin just couldn't recover fast enough and during the most bad periods I couldn't climb for weeks and it was flaking on its own. So far it seems like my skin have been doing great ever since - now climbing almost every second day and no skin issues. There's still a chance that might have been a coincidence (increased day light cycle - I started supplimenting right after the winter) or just less stress in general in this period. BTW I haven't been sipppliment protein so maybe doing it would have given me similar effects. Also I find the skin and bones part quite nasty, so I'm happy that I found vegan options :)

Great video Dave! As a scientist (all be it in a different field) I appreciate that these studies are quite hard to perform with many confounding factors. Having said that I'm not massively convinced by the way they presented the data in ref 11 fig 1. Looks more like P hacking than an honest presentation since they offer no real justification for reporting the CSA at 60% and 70% tendon length. I think the bigger takeaway from that paper is, as you say later, a 14-week resistance training program is good for tendons!

[@climbermacleod]

Agreed. So many studies yet such a poverty of any decent ones.

[@barnosaurusrex]

@@climbermacleod I think another thing to consider would be the effect on trained vs untrained athletes. I can't remember the studies exactly, but I was under the impression that supplementation (e.g. whey) had a greater effect on untrained people when they started training vs an athlete who trains regularly. I imagine the response of finger tendons to training of a reasonably good climber with good nutrition vs an untrained volunteer will further confound any conclusions.

[@Matt.Usherwood]

[@LoveAndClimbing]

Dave, I'm less interested in stuff you don't take, and more interested in stuff you DO take (or would take in some common situation). I can sniff a scam; I largely came to the same conclusions about collagen as you did from my (much less qualified) reading. But I'm sure there are things that work which I just don't know about, and things I don't know about prioritizing the things with strong evidence for efficacy. Here's what I do take: 1. Whey: it seems like a fairly balanced protein from another source with adequate leucine would probably be about equivalent. I also get significant dietary protein, usually from Icelandic yogurt, meats (chicken, beef, occasionally pork), eggs, and legumes. 2. Vitamin D: I actually haven't come across much with regards to athletic performance, but there's a ton of health benefits to this--I find that I do need to take this in the winter months. 3. Creatine: subjectively, I don't feel like this does anything, but the evidence seems to back it up, so I'm taking it daily. 4. Beta alanine: before workouts, seems to create higher-quality sessions, especially with regards to a wide variety of exercises (I prioritize the most climbing or goal-specific exercises first, because later exercises tend to be lower quality due to fatigue, but beta alanine seems to help with this). This seems fairly aligned with the literature. 5. Omega-3s: partially I take these for cognitive effects, but they do seem to have some evident effect on joint health in the literature. 6. Live cultures/probiotics: I don't know if this is actually "supplementing" since I tend to get these from foods, but there seems to be evidence that live cultures and fermented foods have impacts on mood and energy; yogurts in particular are a big part of my diet because they also provide high-quality proteins. 7. Anti-depressant foods: again not really a supplement, but since seeing your video on antidepressant foods, I've prioritized a number of foods with high AFS; particularly bell peppers which were previously not in my diet much. 8. Fiber: especially during a caloric deficit I'll prioritize fiber to help with satiation. Is there anything you'd add to this? One interesting thing I DON'T do is caffeine, at least not very often, and I'll actively avoid it before climbing. The benefits for energy are clear and I do see benefits for resistance training, but for actual climbing, it seems to cause an increase in anxiety that is more detrimental to my climbing the more heady a climb is. I'm a trad climber who's fairly comfortable with runouts, but with enough caffeine in me I even start having pause on generously-bolted sport routes. It's just not worth it.

[@climbermacleod]

I mostly just take the vitamin d and try to get the rest from food (except fibre), but your list sounds pretty good and I guess fits in well with what else you eat.

[@kimsperling]

Thanks a lot for another insightful video and food for thought. It would be interesting to see if a group of climbers with a collagen rich diet would show better tendon health compared to a group that eats mainly lean meat or maybe even follows a vegetarian diet. I live in Korea and a lot of dishes consist of fatty meat like for example pork belly (including ther skin) or chicken feet. I did feel bad about the high amount of fat because of the calories involved, but now it seems that this might not be as bad, as it could come with a potentially beneficial collagen boost for my tendons for free.

[@amuerteclimbing]

Thanks Dave! Actually for me the most useful thought was about relying on supplements and missing some other nutrients. Concerning collagen, I'd also consider people's gastrointestinal conditions like low stomach acidity or some other issues which could make peptides absorption easier for them then digesting real meat. And I'd be grateful for a video on creatine supplementation!

[@TheJust22az]

What many of these studies fail to take into account is the level of resistance training, if any, among older folks. As someone who is in their 60's and does resistance training 5 times a week, collagen is one of many supplements I take and believe are vital in my overall health care regimen.

Anecdotally I've notices a huge difference in my skin and ligaments since I've started supplementing. Like my skin is entirely different and more elastic, stronger.. I now have dead skin remain intact to the point where I have to exfoliate..I haven't had this happen since I was a child.

Love it, please more like that!

Another fantastic video!

I'm keen to hear your take on Creatine - the only supplement I take. I also tried a cheaper version of Athletic Greens - it was truly revolting and whatever benefit I had was probably down to the extra glass of water of a morning; but maybe I didn't give it time.... Would be great to see your take on that too.

How does this relate to your thoughts relating to bone broth? I understand not wanting to waste money on supplements but for instance chicken backs are usually a buck or two a lb here in the states, and it seems these types of foods have been common and preserved in more native diets (native Americans through mexico, various brothy soups in Asian countries etc). There’s lots of stories within the western price circles of natives eating marrow raw, cooking all the leftovers into soup etc. Seems like beyond the idea that supplementing collagen may be detrimental that consuming gelatinous portions has been a large aspect of more traditional eating

[@climbermacleod]

Yes bone broth is good nutritious food. If you like it, go for it. As you say you can make it very cheaply as well.

[@shokland]

Another great video. I really appreciate your scientific rigor and commitment to transparency. Is there a dietary difference between supplementing you’re normal nutrition with animal or vegetable based protein?

[@climbermacleod]

Thanks. Yes, with the plant proteins you just need to take care to blend some different sources since some of them have lower amounts of certain aminos.

[@thomasmehringer8870]

Thank you Dave! I am interested in a closer look on creatine and whey isolate.

[@mrtoocool5324]

What are your thoughts on bacopa, ashwangha, rhodiola? do a video on adaptogens

[@joshpennwatson]

Really interesting as always Dave, would love to hear your thoughts on creatine, it being one of the most common and, in climbing over the years, controversial

[@Mookiethedog]

Damn I started supplementing collagen in early August. Looking forward to hearing your take on it! I wonder if age factors in? Im almost 60 and im told us old farts dont produce as much collagen. Also other than collagen im a plant based athlete. I could listen to you all day bud! Definitely strength training is magic!

[@robertjakubowicz3265]

Would love to hear your take on all the bigger supplements usually used by climbers/strength trainers.

[@jrisner6535]

Would love you to make a 5 minute version of this for general consumption... Most people will not have the patience!

[@climbermacleod]

Most people do have the patience, but you can just use the chapter markers or see the short version here kzbin.info114EDZcKCk0?feature=share

[@jrisner6535]

Ah the short is great, nice one

[@RogerIElliott]

Fascinating Dave, thanks.

[@AnonUser2023]

Great video dave

Dave, I'm really curious about your thoughts on Huel (Black - low carb), marketed as a 'nutritionally complete food'. Compared to AG-1 (which I think is marketed using similar language), Huel seems to contain appropriate levels of protein (40g pea/rice), Iron (70% NRV), vitamin D (80% NRV) and fatty acids (around 5g each for Omega-3 and Omega-6) per dose. I use it to supplement a diet mainly consisting of otherwise unprocessed foods and animal protein, plus creatine. Been using it for years and I think it works well for my lifestyle. This is reason enough for my own personal justification but I am keen to hear your take. Your recent guest appearance on Climbing Stuff was good craic!

[@metyu3730]

more videos on suplements you do not take (or take) would be very interesting, especially your thoughts on creatine as a supplment for climbers :-)

[@connormccafferty5288]

Thanks for this Dave! I'm curious to hear your thoughts on creatine.

[@knightonwarbeck1969]

Much respect to you Dave. Great channel and very informative content. A study is study of how a thing affects OTHER PEOPLE, NOT how it affects you. Try a collagen supplement for 30-90 days. See if there are positive results for you. I discovered collagen does not benefit me after 60 days at double the "recommended" dose of 10g per day. I went up to 20g per day and my nails, skin, and hair remained unchanged in their "quality". A close friend and his girlfriend see remarkable results after 30 days at 10g a day. Now, a silica supplement like one by a German company DOES provide positive results on my nails, hair, and skin. Try and see.
