I dont know of an Aussie stockist. I'm looking on iherb and mthfr dot net to see which ones are best.

The test is Medicare rebateable apparently. I know sometimes people are charged $50 but you should be able to get it bulk billed. I'm ordering the pills now though I havent had the test yet. My GP is a PITA to get in to see. If you do get the test, make sure it's for both mutations, not just C677T.

My green smoothies include:
Kale
baby spinach
beetroot (not a lot)
avacado
banana
strawberries and other berries if I have them
sometimes carrot or apple

Things with lots of natural folate. I did not know cos lettuce was high in folate. I add the fruit to disguise the tast, though strawberries are also good for folate.

You can add cacoa or cocoa as well. Whatever you like really. I use my TMX, so nothing is wasted like with a juicer. Just add ice or water to thin it out.
