It's EXTREMELY important to get an iron test before supplementing with iron. Iron overload is very toxic and the body lacks the ability to effectively remove built up iron. My iron levels have always tested on the high side and an iron supplement would be just about the worst thing I could possibly take for my health.

[@markarnold4367]

Correct, I have genetic haemochromatosis which is exactly that! the noticeable symptoms are very much in line with anemia.....long term iron overload generally leads to liver cirrhosis followed by death! So all in all not something should be self diagnosing!!

[@McAwesome363]

@@markarnold4367 Exactly. It's important to recognize that people differ in their ability to uptake iron. We should not be self diagnosing ourselves based off of preconceived notions about who should be deficient in iron but rather based on objective measurements that prove whether we need supplementation or not. As for myself, I have been following a vegetarian diet for over a decade while doing long endurance training, and despite the common advice you hear on the internet that vegetarians and athletes need iron supplements, my iron levels have always been high. Carefully watching my diet to avoid processed foods with fortified iron and regular tea consumption have been the things that have kept my levels from reaching toxicity. Iron supplements often come with 100% or more of the daily value of iron, which is great for treating a known deficiency with regular follow up testing, but popping a pill everyday because you fear deficiency could be a disaster waiting to happen.

Ive posted more blood tests on youtube since 2009 than anyone else. ZERO of my athletes develop any deficiencies.

[@icantgivecredit871]

I think poor sleep is also a factor. From lab tests, I know I am not iron deficient - yet chronic fatigue, difficulty doing basic physical tasks, and long recovery time are all things that are perpetually part of my life. Sometimes, I'll have a good day and can really hammer the pedals... but a long recovery time always follows. The notion of "early to bed and early to rise" (easier said than done) would probably do wonders for me and many others.

[@ryoukokonpaku1575]

Definitely, especially if you're particularly stressed the night before. Either because of work or other things which makes your sleep quality suffer. I found that having good sleep was key to actually feel fresh again the next day to tackle workouts.

[@icantgivecredit871]

​@@robp3431 I have definitely been considering that I am being affected by hypothyroidism, despite tests' indicating "normal" function. However, I can neither rule out poor sleep nor attribute it to my fatigue, until I fix said sleep habits. I can say that I have increasingly been identifying with common symptoms of hypothyroidism, including fatigue/muscle fatigue; cold intolerance; dry skin; and maybe even hair loss. Please let us know if you find out more; you and I (and others) may be in the same boat together.

[@kiverrussell8369]

From my own personal experience/anecdotal point of view I would say the difference between getting 5-6 hours sleep a night and 7-8 hours is night and day in terms of my recovery as I entered my mid 40's. Less niggles, less sickness and better energy levels. Yes, a varied, primarily plant based, whole food diet plays a vital role too but I think without good sleep habits it can only achieve so much. Of course Dylan has a vid on sleep too!

Here in Asia, the most common, cheap, and plentiful source of organic iron is the leaves of the Moringa oleifera plant. Just 100 grams of leaves can supply 31% of your RDA. The 100 grams of leaves also contain iron-promoting minerals such as Vitamin C that meet 62% of your RDA Vegans will greatly benefit if they eat Moringa oleifera leaves.

[@Anxiouslydisengaged]

Great video and good info, Dylan. I must admit I was surprised to see you not break down iron nutrition into some of its more individual components, particularly hemoglobin and ferritin. I’ve been an endurance athlete for quite a while, and started to get all the symptoms you described a few years ago while on a Whole Foods, plant based diet. I concluded I may be iron deficient, and got tested. Hemoglobin was fine and ferritin came in at like 29, which is technically in range (29-400 usually), so nothing was flagged. I went deep into the literature on my own, and found quite a bit of research advocating ferritin levels to be at least 50, hopefully 70, and ideally above 100 for endurance athletes. I started supplementing and after 6-12 months, my ferritin had massively increased and all my symptoms were gone. I think this would be helpful territory for endurance athletes to know, imagine you’ve dabbled in this, and would be interested to know what you’ve found in the science as well.

[@daveanolik8837]

Did you continue with a plant-based diet? Supplements only? Asking because I was just tested, low Ferritin, and I’m a vegetarian.

I did not. I still don't eat much red meat though. My ferritin levels still drop without supplementation. There's some research showing that once you've dropped, it can take a while for the body to maintain higher levels on its own, but I'm still not entirely sure why my levels haven't stabilized on their own. I'm trying to decrease the amount of supplementation over time and have those ferritin levels stay high.@@daveanolik8837

Regarding bloodwork: according to my partner's knowledge (medical professional) it's important to perform a wider panel for iron, that will include TIBC (total iron binding capacity), transferrine, ferritine, hemoglobine (CBC) and iron. That is if you want to get a full picture, as 'just iron' test will not suffice. While you are doing such tests, you can also do the Vitamin D check, as it has some obvious crossover syptomps with iron deficiency (e.g. being tired all the time, etc.).

It is true that iron deficiency should not be self diagnosed. In western populations Haemochromatosis (retaining too much iron) is one of the most common reccesive genetic disorders, and not immediately obvious, even to GPs. It also includes symptoms of tiredness and lethargy. Taking iron with that condition would increase risks to heart liver and joints. On the other hand, our national blood service, the Australian Redcross Lifeblood, currently has a standing recommendation for women 18 - 45 yrs old to take a single course of iron supplements between blood donations, based on research they've been doing over the past two decades or so. Professional athletes are also subject to some special advice around donating blood or plasma.

[@thelifeofdev95]

An absolutely necessary video! I get blood work done regularly due to other health issues and my iron tends to drop like a cliff during heavy training blocks and race season. I started noticing weakness and breakage in my hair during these heavy training blocks and general fatigue as well. In my most recent blood test, my iron stores were "near depletion" from what my doc said, who then prescribed pre-natal supplements, which have made a massive difference. My diet is great and I'm very cognizant about getting everything I need. Supplements are great but maybe I'm just not getting enough from dietary sources--maybe it's time to reassess.

Really tasty!

I've been accused of a tendency to "Florentine everything"; spinach pasta and spinach/almond pesto is just plain delicious, though. Good to know that there's a scientific backing for why I like to eat the way I do, especially after a long ride.

I had been unusually fatigued for months. Since my hemoglobin levels were normal, doctor dismissed it. It wasn’t until I went back and talked about feeling muscle fatigue that she tested ferritin and iron binding capacity. Uh oh! Non-anemic iron deficiency. Doctor Started me on iron supplements and noticed very good recovery which has taken a couple years. I had a good diet. Full Recovery from iron issues takes time. Women in particular are subject to this because of monthly blood loss yet many doctors don’t test beyond hemoglobin levels. Advocate for yourself.

I am intrigued by this monthly blood loss problem (and too lazy to search out scientific research) so am hoping you’ll have some experience and info to guide me in my quest for answers. As far as I can tell from those I’ve known intimately during my life (not many endurance athletes), blood loss is not really significant during the cycle, certainly not compared to donating blood or do you really lose half as much every month as you’d donate every two months (of course if a female endurance athlete also donates blood every 2 months then things start getting critical). So I’m wondering, if it is not the amount of blood per se, whether this blood is not altered in composition, having for example much more concentrated iron products and maybe other differences.

bloodwork test during the summer revealed that I am low in iron, And that it’s the absorption rate that’s causing the deficiency. Have yet to do anything about it, but this video has helped me open my eyes to the topic, Going to bring it up to my doctor, Hopefully he suggests supplementation

Let’s not confuse iron deficiency with aging 😢

[@oldanslo]

The paradox with aging is that in order to maintain performance you have to increase your training volume while at the same time your capacity to train and recover is diminishing. More training, more tired.

[@michaelw7115]

Easy solution to that, don’t overdo it when your young and you can build up volume for decades ;-) 56 and still getting better.@@oldanslo

"Aaaand still didn't win. Don't for get that part." lmao Great use of self depcricating humor. Informative and entertaining!

[@BulletproofCycling]

Nice video buddy - this is something that I promote a lot and with my UC problem and bleeding etc I have to supplement it a lot - ps taking out the trash is always an energy sapper hahaha - I also have Vit D plus several B vits measured - especially B-12. Great work as always

[@willmcallister8464]

I've got haemocromatosis so go too much iron but interestingly I'm now cycling 75 mile a week to work & my ferretin levels have only increased by 4 points in a year which is impressive

[@catherinepeele5217]

Great summary on an important topic. As someone who has required multiple rounds of iron infusions, I can attest that iron deficiency and even anemia frequently go undetected and untreated/undertreated. Iron deficiency (low ferritin) can feel exactly the same as full-blown anemia, but a CBC at your typical annual physical does not measure ferritin; a full iron panel has to be ordered for that. At several times when I was anemic, PCPs might send me off with a casual recommendation for iron pills, but never require followup bloodwork in the near term. Permanent progress only came after a new PCP took me seriously and sent me to a hematologist. Iron infusions have been life-changing. To anyone reading this who has a suspicion that they might be suffering from iron deficiency or anemia (particularly if you menstruate), please advocate for yourself and ask your doctor for an iron panel. It's a debilitating condition with potentially life-threatening complications.

Also, low iron may be an indication of coeliac disease, which I was diagnosed with in June. My ferritin level has been declining slowly for about three years, reaching as low as 13 ug/L (normal range 20-200). My red blood count went below the minimum plus my haematocrit and my mean platelet volume. Since embarking on a gluten-free diet and supplementing with ferrous bisglycinate, my iron level is on the mend.

[@catherinepeele5217]

@@dpstrial Yes, there are so many potential causes! Glad you pinpointed yours and are on the road to recovery.

[@martinextejt3453]

I know that in "Senior" Multi-vitamin supplements for Men the iron is removed. It's also suggested that senior men do not use cast iron to cook because of excess iron. On an individual basis for the senior athlete my learning from the video is to ask your doctor and test.

I eat chicken/pork liver. Love it and contains tons of iron

Excellent information. And very funny too!
