Trends in mineral supplements are like music genres, you can pick which ‘decade’ they were formulated very quickly. But instead of going by clothes, hairstyles or even the style of accompanying music video, it’s all about the form – the ‘thing’ the mineral is bound to, that gives the game away. While mineral carbonates , sulphates and oxides seem to many of us contemporary clinicians, pre even MTV, amino acid chelates take me back to a time when I was wearing shoulder pads in everything, even my pyjamas. It was called power-dressing and needed to be adhered to 24/7, you see. Then along came fancy forms like orotates, aspartates, hydroxyapatites as we moved confidently into the 90s…well, as confidently as you can, when the Y2K bug may ‘end life as we know it’ come NYE. The dawn of the new millennium saw us embracing picolinates and bis-glycinates in a big way and for the last little while, citrates have really been having their time in the sun. But you know what…here’s a few things you MUST know…
- These are trends, not truths
- Every mineral has its Mrs Rights and Mrs Wrongs, in terms of chelates and ligands, and these are not the same from one mineral to the next e.g. Zn sulphate is a decent form of available Zn, Mg sulphate, an over-priced laxative
- In almost every case, there is simply NO strong consistent body of evidence that one form of a mineral is superior in terms of bioavailability, regardless of what companies tell you..go on I dare you…check their references and then do your own quick literature search away from the cherry picker
- Nor is there one mineral form that is above adverse effects in everyone
Brutal. Welcome back to ‘tough talkin’ Tuesday’ 😉 But we have to state these facts because we need effective supplements for our patients and not understanding the different forms that are better (but not ‘best’) compared with those that are inferior (this we do have some evidence of) threatens the integrity and efficacy of an otherwise well thought out prescription. So here’s where you might want to move into a room away from everyone and lock the door…because you’re likely to scream. One of, if not the most commonly used single nutrient supplement almost across the world, is calcium. After almost 30 years of studying supplemental forms side by side, can we conclude which form is best? No. How about ‘better’….hmmmmm yes…maybe…citrates look good going by some markers but not all and vice versa for other commonly seen forms. I can say this, because I have followed the research over the decades, reading the primary papers, like this excellent one by Bristow et al from 2015 that should burst quite a few people’s ‘best!’ bubbles. Have you screamed yet?
I scream. Often.
Because I am frustrated by the lack of research that we need, to be more certain of our preferred forms and then even more frustrated by companies’ claims that the evidence is already in, and guess what, theirs wins!
But it comes back to the same call to action for us – know your nutrients and specifically, where possible, get familiar with the Mrs Right and Wrong for each mineral! Know that the supplemental forms that work for zinc will not necessarily be a good match with iron, that any company that formulates their minerals in the vain of ‘one form for all’, be that glycinates, citrates, picolinates…well they’ve probably got a good fit for some of those minerals and a shocker for others. And as always truly check efficacy with follow up bloods, if you had baseline deficiencies evident in lab tests. I know, that’s not everyone’s model of practice right, or ideal but not always ‘real’, so alternatively, if you are prescribing based on clinical signs of mineral deficiencies that should respond quickly to repletion e.g. white spots on nails in the case of Zn deficiency, then ensure that they do!! If they don’t and your patient is compliant then consider switching form! When I see good practitioners’ prescriptions let down by poor choices of nutrient forms, well, that’s when I need to go into that separate room once more….can you hear me? Ooh that reminds me of something else dated by Mike and the Mechanics: Silent running “Can you hear me?!”😂
Let’s make sense of the over-arching nutrition principles, that will profoundly change your understanding and application of this modality Truly understanding the ‘big’ concepts, so often overlooked, or incorrectly taught, ensures you get the critical ‘small’ detail in your nutritional prescriptions right. In this 4 hour recording, together with key clinical tools, we talk about the tough stuff: dose-response curves, active versus passive stores and excretory pathways and ooh lah lah…the myth of taking ‘activated vitamins’. And yes we even mention Mrs Right/Wrong forms for minerals. Even those who feel satisfied with their original training – will find a lot in this critical review that is new, insightful and truly practise-changing!
