Supplements for fertility and preconception
Methylfolate, vitamin D3, the preconception formula, omega 3 DHA, zinc and iron: built on UK guidance, with the GP line where it belongs.
How to choose a preconception supplement
This page follows UK guidance: folic acid 400 micrograms a day from before conception, vitamin D daily, and a GP conversation if you have been trying for more than a year, or for six months if you are over 36.
Why these
Methylfolate (5-MTHF) 1000mcg Capsules: Folate as methylfolate; folate contributes to maternal tissue growth during pregnancy.
Vitamin D3 & K2: Vitamin D contributes to the normal function of the immune system and the maintenance of normal bones.
Preconception Formula: The preconception formula, with what it contains stated.
DHA: DHA omega 3; maternal intake of DHA contributes to the normal development of the brain of the foetus.
Zinc Picolinate Capsules: Zinc contributes to normal fertility and reproduction.
Iron & Vitamin C: Where ferritin is low.

Common questions
What does UK guidance say to take before conception?
Folic acid 400 micrograms a day from before conception until twelve weeks, and vitamin D daily. Some people are advised a higher folate dose by their GP.
Is methylfolate the same as folic acid?
It is the form found in circulation and it meets the folate need; the UK guidance figure refers to folic acid, and your GP or midwife can advise which suits you.
When should we see a GP?
After a year of trying, or six months if you are over 36, or sooner if you have a known condition.
