Yet another super-helpful part of Iron-Land has been mapped!! Ever struggled to correct chronic iron deficiency in athletes or even just weekend warriors? Yep, me too. One of the key barriers being the 2-3 fold rise in hepcidin in response to exercise. Hepcidin whose day job is an inflammatory signal that two-times as an iron uptake blocking agent at the small intestine. In addition to other exercise-induced factors that either reduce Fe uptake or increase losses, it really is no surprise that these cases can be hard to treat. However, a recently published small Australian study has brought to light some constructive new information. Similar to the often talked about ‘anabolic window of opportunity’ whereby we encourage people to consume protein +/- CHOs within a short time-frame post-exercise to optimise exercise outcomes and negate negatives, these new findings imply the same might be true for optimal Iron uptake. But only in relation to exercise done in the morning!
The key finding was when individuals consumed iron after 90mins of exercise in the morning they exhibited higher uptake than both when they took the iron at the same time but didn’t exercise beforehand or took it after exercising at night.
This is a game-changer for potentially ALL our patients who struggle with iron absorption. With the key take-home being…not just take your iron preferably in the morning which we already know (when hepcidin is naturally lower as part of its diurnal rhythm) but before you pop that pill, pop on your sneakers and get busy sweating! How on earth might this be working? Well this study demonstrated that while hepcidin rises after exercise typically for up to 6hrs…it is not yet ‘up’ and blocking within the first hour – gotcha! But why would this mean an even greater uptake compared with the same iron at the same time in the same individual…but a resting version of themselves? Because exercise may in fact cause a transient leaky gut post exercise & enhanced nutrient uptake may be its silver lining! A small study that actually punches above its weight, this one is worth the read – via a great comprehensive summary on Medscape if you have it or you can check out the abstract.
Our ever-expanding Iron knowledge gives us great hope for the improved understanding we are likely to reach with all nutrients in the future. Let’s not forget Iron has about a 70 year head-start on other microminerals such as Zinc and almost a century on Selenium, which was identified to be essential in just 1979!
And the contrast is apparent anywhere you care to compare and contrast the ‘older’ with the ‘younger’ nutrients. Just look at iron studies. A personalised detailed account of each individual’s iron story: how much you’re consuming, how effective you are at absorbing what you’ve been offered, how hungry that makes you for more and what good stores mean to you (not some fictitious average male or female)! All told through 4 distinct but inter-related markers: serum iron, transferrin, transferrin saturation and ferritin. What can we glean from our current routine assessment of Selenium in contrast? Their short-term Se intake…yep. Looking forward to the multi-parameter markers of each individual nutrient we just might have at our fingertips in the future, thanks to iron nutrition which continues to teach us how sophisticated nutritional physiology really is 🙂
We know the most about iron and yet we know there is always more to learn. And who better to teach us this than our clients with iron deficiency or iron excess? Need some help getting across the most important aspects of recognising and correcting each iron issue in clinic? We released an Iron Package earlier this year for this very reason. It covers how to really read iron studies (with a great cheat sheet), how not to fall for a fake (deficiency) and what the best supplements and dosing regimes look like and how that differs in pregnancy, athletes, those with marked gut issues and other key groups. It’s your 1 stop iron shop.
We’re not deaf…we heard that stampede of Iron-Inundated Practitioners!
Our recordings and clinical resources for improving your skill-set in all things iron including, your accuracy of diagnosing deficiencies, pseudo-deficiencies & excesses, plus radically rethinking the best treatment approaches for each scenario…have been some of our most popular. Because nailing iron (pardon the pun) is harder than we were all lead to believe and at least 1 ‘iron maiden’ or ‘iron man’ walks into our practice every day, right? So we’ve brought together 5 extremely popular UU30’s on Iron into one bundle for the price of 4! So if you’re more than ready to graduate from ‘iron school’, now’s your best chance!
1. So You Think You Know How to Read Iron Studies? (≤30 min audio + Cheat Sheet)
Overt Iron Deficiency Anaemia or Haemochromatosis aside…do you understand the critical insights markers like transferrin and its saturation reveal about your patients iron status? Most practitioners don’t and as a result give iron when they shouldn’t and fail to sometimes when they should. This audio complete with an amazing cheat sheet for interpreting your patients Iron Study results will sharpen your skills around iron assessment, enabling you to recognise the real story of your patients’ relationship with iron.
2. Pseudo Iron Deficiency (≤30 minute audio)
The most common mistake made in the interpretation of Iron Studies is this one: confusing inflammation driven iron ‘hiding’ with a genuine iron deficiency. Worse still, following through and giving such a patient oral iron – when in fact it is at its most ‘toxic’ to them.
This audio together with some key patient pathology examples will prevent you ever falling for this one! Learn how to recognise a ‘Pseudo Iron Deficiency’ in a heartbeat!
3. Iron Overload… But not as you know it (≤30 minute audio)
We’re increasingly seeing high ferritin levels in our patients and getting more comfortable referring those patients for gene testing of the haemochromatosis mutations; but, do you know how to distinguish between high ferritin levels that are likely to be genetic and those that are not? This can save you and your patient time and money and there are some strong road signs you need to know. In addition to this, what could cause ferritin results in the hundreds if it’s not genetic nor inflammation? This Update in Under 30 summary will help you streamline your investigations and add a whole new dimension to understanding iron overload…but not as you know it!
4. So You Think You Know How To Treat Iron Deficiency? (≤30 min audio)
And then you don’t. The reality is we all struggle at times with correcting low ferritin or iron deficiency anaemia – so what have we got wrong? In spite of being the most common nutritional deficiency worldwide, the traditional treatment approaches to supplementation have been rudimentary, falling under the hit hard and heavy model e.g. 70mg TIDS, and are relatively unconvincing in terms of success. New research into iron homeostasis has revealed why these prescriptions are all wrong and what even us low-dosers need to do to get it more right, more often!
5. So You Think You Know the Best Iron Supplement, Right?! (≤30 min audio + Iron Supplement Guide)
Iron supplementation, regardless of brand, presents us with some major challenges: low efficacy, poor tolerability & high toxicity – in terms of oxidative stress, inflammation (local and systemic) and detrimental effects on patients’ microbiome. What should we look for to minimise these issues & enhance our patients’ chance of success. Which nutritional adjuvants are likely to turn a non-responder into a success story and how do we tailor the approach for each patient? It’s not what you’ve been taught nor is it what you think! This comes with a bonus clinical tool, a fabulous easy reference guide – to help you individualise your approach to iron deficiency and increase your likelihood of success.
You’ll never look at iron studies or your iron-challenged patients the same way.

And then you don’t, right? Because if my experience is anything to go by, there are some patients that just don’t respond to the usual iron repletion strategies. Depending on how low their ferritin is, this can then precipitate ‘practitioner panic’ (we’ve all had it right?!) where we’re inclined to go higher & higher with the dose and number of doses per day. Typically, this also fails. I hear about this from other practitioners all the time and I see the ‘normal’ doses of iron sneaking up and up. Remember the days when we couldn’t get a non-pharmacy supplement with over 5mg elemental iron in it and now we have > 20mg? But still, I hear you say, this fades into insignificance when you think about the standard medical model for iron correction which provides 100-200mg/day and you’re right.
Gee… after hundreds of years of knowing about this deficiency and being the most common deficiency word-wide, you’d think we had our supplemental regime nailed.
But that’s where you’d be wrong. (more…)
While I did diagnose this one correctly, I didn’t get 100% in this quiz – Can you? Speaking of the devil, Medscape, has this great little visual quiz to test your knowledge about physical signs & other hidden clues of nutritional deficiencies.
While we all know there can be a lack of specificity when it comes to some deficiency signs…like glossitis…eyeyiyi..naming a nutritional deficiency that doesn’t include this sign would be a tougher question 😉 but what a great reminder of some quirky things you may have forgotten or in fact deficiency features you may not have even known about.
A gem I love and apply frequently, is about zinc the ALP levels…watch out for the that later in the slideshow quiz.
Also note the distinct difference in opinion when it comes to vitamin D adequacy – with Medscape citing blood vitamin D result < 75 nmol/L unequivocally associated with osteoporotic change…in contrast to the …’anything over 50 nmol/L is a bonus’ line we’re being fed here in Aus and NZ! While we may not ever see some of these severe deficiency presentations walking through our doors – you can’t be so sure…given the reported resurfacing of scurvy in good ol’ Sydney just last year!
Is it just me? I love going back to nutrition 101. So tomorrow with your cuppa…test yourself and then let us know how you go 😉

Cheesy I know! 😉 However, recently the issue of knowing when to use Withania somnifera & when not to, came up again in mentoring so I thought it’s probably a good one to share. Withania, aka Aswagandha or Indian Ginseng, has become a favourite adaptogenic prescription for many practitioners, myself included. I remember learning specifically (about a million years ago!!) that this herb is ‘warming’ & ‘nourishing’, thanks in part to its iron content. In a traditional medicine context, it’s used for those particularly vulnerable populations such as children, the pregnant, the elderly and the malnourished, boiled in milk as a tonic. These ideas always stayed with me, and lead me to only use Withania in similar patients and presentations with good results. (more…)
Well here’s a thought…the ‘Superfood’ nutrition movement has just about eaten the South Americans out of quinoa and the Pacific Islanders out of coconuts..isn’t it time for a local hero? I get a bit despondent when any new food is touted as a ‘Superfood’ anyway for all the obvious reasons but this is heavily compounded when this so-called ‘Superfood’ and the bankable gross exploitation of this foodstuff comes at a huge cost: whether that be in terms of food-miles, another population’s access to their food staple or the radical change in land management in these countries that often follows, e.g. think palm oil plantations.
“I need a (Local) Hero!” – cue Bonnie Tyler soundtrack & wind machine 🙂
These days it seems like patients can almost be divided into two groups: those that have a tendency to iron overload and those that struggle most of their lives just to keep ferritin in the red…and what a struggle it can be. So many clients have spent years taking every form of iron there is in high doses, trying to improve their intake of dietary sources, working on their digestion etc etc but still those numbers can fail to really pick up. (more…)
We’ve just had another mentoring case in which a 40 something female with deficiencies of almost all other minerals but ‘pretty normal ferritin levels’ presented with a range of endocrine problems and arthralgia. Sounds as if iron’s not the problem right? Except that in this case her iron studies also tell us that her transferrin saturation % on last check was 48%. The diagnostic criteria for hereditary haemachromatosis (HH) necessitates elevated ferritin – to indicate that the iron stores are reaching saturation, however, while this becomes evident at relatively young ages in men (20s-40s), who have no specific excretory pathway for iron, is this still appropriate in menstruating female, whose monthly periods may mask the HH tendency with regard to ferritin? I’m guessing you know what my answer is already! 😉
Some would argue that HH, in spite of being an inherited disorder, is only clinically meaningful once the ferritin is elevated ( earlier and more potent elevations are seen in people possessing the C282Y genotype) but again this is very much up for debate in the current scientific literature, with a lot of research concluding that the transferrin saturation (also referred to as the transferrin ratio) being an important prognostic indicator for various chronic diseases including CVD.
When we go back to basics and remember the higher the transferrin percentage the more iron is being delivered to tissues around the body (whether they like/want it or not! so we refer to this as being ‘iron dumping’) and the higher the serum iron, the more unbound iron is in the system – a key source of oxidative stress..it becomes patently clear that these two parameters are important early warning signs of a tendency to iron overload, increased risk of heavy metal toxicity and already active mineral imbalance. So in future keep your eyes open for women with fasting transferrin saturation values that consistently sit above 35% and men, > 40% and if you do see a series of suspicious values – consider the genotype test through mainstream labs.
