I'm a little late to the
www.haartest.nl party, but I've done some digging and I think I have a pretty clear picture of how things work in The Netherlands.
First of all, haartest.nl has the exclusive rights in the Netherlands to supply the actual hair test, but ALSO the supplements from Trace Elements. I've contacted many online webshops, mostly UK based because they are a lot cheaper, and they said they cannot ship Trace Elements products to The Netherlands due to exlusive rights from haartest. So we are basically stuck with
www.haartest.nl if we want to go the TEI route.
Secondly, some of the products that haartest sells have their own weird names, like Sympia and Adrena. These supplements are specifically made for The Netherlands, because their original counterparts, like Sympia <-> Sym-Pack III, have ingredients that are not allowed for sale in The Netherlands, hence the need to produce a slightly different version of the product. For example, Sympia is missing Whole Thymus Glandular (bovine) and Whole Pancreas Glandular (porcine). They assured me that the Sympia, which is a slightly modified version of Sym-Pack III, is at least as good. This is probably the reason why those supplements are being extra expensive.
Third, Fulvic Clean is probably a product that hairtest.nl advises and not TEI. Fulvic Clean is fulvic acid, which is one of the main components found in shilajit. It helps to detox, chelate heavy metals, and binds to minerals to help them enter your cells easier, at least that is how it is being promoted. If it's true it might be beneficial and speed up the TEI healing process. The price of Fulvic Clean is high though, if you look around on the internet you can find fulvic acid for less. I have this shit lying around, but unsure how and when to use it. I've tried it and felt like utter shit on it, perhaps it is chelating heavy.
So all in all this is the status of TEI hair analysis in The Netherlands. I'm still unsure if TEI could be sped up, by eating the right foods from the beginning instead of the recommended foods from TEI. The reason is that it takes like 2-3 hair tests to see your real oxidation rate and they could be recommending foods for your 'fake' oxidation rate on the first and second hair test, this might slow down your process. Last but not least, the amount of 'supportive' amino acids in their supplements is low, like really low. You have to combine those supplements with food, and I think the food you eat has way more amino acids than those supplements. So I'm doubting if these amino acids in their supplements are doing anything 'supportive'. Perhaps they know their shit and you only need a fraction of the supportive amino acids to make the minerals and vitamins work.
If anyone has some questions, don't hesitate to ask. I'm on TEI myself for 2,5 weeks right now. Not sure if I should take a 1-2 week break after 1 full month of TEI supplements. Still need to decide on that.
