And not just supplements - things like coconut oil. The ones I hear all the time are Vit D3, and B12.
I take a few things, but I'm always wondering if I'm missing something important!
This is my current regime -
Vit B12 in the morning,
2 tbsp coconut oil,
3 brazil nuts for the selenium.
Iron with orange juice (for Vit C) late afternoon
Magnesium and Vit D3 supps in the evening (with a yoghurt for calcium.)
