GMO & Organic

I don’t think many care about an “organic” source of micronutrients. What matters is that the original plant sources, the oats, flax, soy, psyllium etc., are purchased from “certified organic” producers: those who are registered (with whatever agency does that in the UK) as having produced the crop without use of pesticides. This would, likely, raise costs to you as such producers are fewer in number.

You may possibly be thinking about the label “vegan” which means, nothing sourced at any remove from animals. This can affect the micronutrients, specifically Vitamin D is most economically sourced from lanolin, from sheep’s wool, and the presence of lanolin-derived D3 forecloses use of a “vegan” label.
