Those ‘still-believers’ look away now. One of the great myths, misconceptions and misunderstandings in nutritional medicine is that supplementation with specific nutrients will produce change specifically in one system, or pathway, which just happens to be the one that the practitioner has determined would benefit most/is targeting. Let me explain myself a bit better. When we give patients any nutrient, in the cases where it’s not simply to correct a global deficiency & therefore improve levels all round, it’s typically on the basis of a specific desirable therapeutic benefit, e.g. some magnesium to help their GABA production…, additional B3 would improve their mitochondria. Beautiful on paper…but like sending a letter to Santa in reality (I did warn you!)
Truth Bomb No.1: There are nutrient distribution pecking orders that have nothing to do with who you ‘addressed’ it to
This dictates that when something is given orally, for most nutrients, the gut itself has first dibs. So the cells of your digestive tract meet their needs before any other part of your body gets a look in. Sometimes the digestive system’s needs can be quite substantial and leave little for any other part of the body…not mentioning any names (ahem) Glutamine!
Truth Bomb No.2: En route to the ‘target’, these nutrients get delivered and distributed to many other tissues – with possibly not so desirable or intended effects!
You may determine that a patient needs iron because their ferritin hasn’t got a pulse…so you keep giving them daily high dose oral iron to ‘fix’ this…not realising you’re making their GIT dysbiosis and gut inflammation worse in the process. Or you feel their mysterious ‘methylation cycle’, happening predominantly in the liver and kidneys, could do with a folate delivery…perhaps ignoring the very worrying fact that their colon may have already had a ‘gut full’. Literally. Hence the concerns and caution against supplementing with folate in patients with established colorectal cancer. So is bypassing the gut via IM or IV nutrients the answer…well yes and no…but mostly no. Read on…
Truth Bomb No.3: Those pathways that use the nutrient you’re supplementing, that are most active in the patient’s body currently – which is determined by many factors (genes, physiology, feedback circuits, pathophysiology) and rarely simply by the availability of nutrients – will take take the next lion’s share of that nutrient
Wanting to nutritionally support someone’s thyroid, you know tyrosine is the backbone of the thyroid hormones, so you include this in the hypothyroid prescription. Will it help? Who knows? Being a non-essential amino acid the body exhibits very complex regulation of its distribution and use – with thyroid precursor availability being only one job on a very long list! And if this was in a patient who is regularly smoking cannabis, due to upregulation of the tyrosine hydroxylase enzyme – there is likely to be more of the supplement headed for even more dopamine production and very little or none reaching in fact your intended target. And don’t get me (re)started on Glutamine – supplements of which in an anxious and glutamate dominated patient will make…G.L.U.T.A.M.A.T.E…right…not GABA! 🙁
Sorry, I know, it hurts right? But these are essential teachings, that tend to have been over-looked or under-played I find, in nutrition education, regardless of training: nutritionists, naturopaths, IM doctors, dual qualification practitioners remedial therapists. Nutritional medicine is a wonderful and potent modality when it’s done well…but we need to revisit some core truths and principles that many of us have missed out on, to ensure we’re not writing letters to Santa.
Let’s start with Micronutrients. Let’s talk 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’. Even those who felt well trained – will find a lot in this critical review that is new, insightful and truly practise-changing!
