FAQs about maca and thyroid function

Does maca impair thyroid function or give you goitres?

Maca is often mistakenly associated with negatively impacting thyroid function as it belongs to the cruciferous vegetable family. These vegetables contain high levels of biochemicals called glucosinolates which can interfere with production of thyroid hormones, particularly in the presence of a low-iodine diet. This may only be an issue for those who consume maca raw.

In Peru, maca has never been consumed raw and it is always cooked. Raw maca may actually be more harmful than good and the beneficial properties of maca are not lost when cooking (see here). During cooking the glucosinolates break down to create a powdered form that is ‘thyroid friendly’. All our maca is  thyroid safe. It is pre-cooked and as such there is little to no risk of negative impact to thyroid function. In fact, traditionally in Peru cooked maca is used to regulate and enhance thyroid function and may actually be highly beneficial for those suffering from thyroid related conditions.
