​Pickup, McNall’s partner, paid for a liver function test at the start of her pregnancy. The results, which she had her naturopath interpret, showed a zinc deficiency and a need for more protein, and she rejigged her supplements, which total 16 at the moment. Pre-pregnancy, she took eight each day. It’s an example of what Pickup called low-hanging fruit, like filtered water and improved sleep hygiene, that can be easily changed to better your health.
