3 vital roles

Belinda Adams Founder, Fertility Hero
"“Going through fertility treatment made me much more conscious of the foundations of my health — not just fertility supplements, but the nutrients my body relies on every day.

Magnesium became part of my own evening routine, and it’s something I’ve continued with ever since. When we created ours, I wanted a meaningful dose of magnesium bisglycinate in the simplest possible formula — just magnesium and the capsule, nothing unnecessary."

FAQ

Why magnesium bisglycinate?

Magnesium bisglycinate is a chelated form of magnesium, where magnesium is bound to the amino acid glycine.

We chose it because it’s well tolerated and suitable for everyday use, including for people who find some other forms of magnesium harder on the digestive system.

How much magnesium does it provide?

Two capsules provide 300mg elemental magnesium, equivalent to 80% of the Nutrient Reference Value (NRV).

When comparing magnesium supplements, look at the amount of elemental magnesium, rather than simply the total weight of the magnesium compound.

When is the best time to take magnesium?

Magnesium contributes to normal psychological function and normal functioning of the nervous system, which is one reason it has become a popular part of evening routines.

We don’t think you need to take magnesium specifically at bedtime, though. Fundamental Magnesium can be taken at whatever time of day works best for you.

Why take magnesium when trying to conceive?

Magnesium has a role in the process of cell division and contributes to normal protein synthesis and normal energy-yielding metabolism.

We see good magnesium nutrition as part of the broader nutritional foundations of preconception for both women and men, rather than as a standalone “fertility supplement”.

Can I take it during pregnancy and breastfeeding?

Yes. Fundamental Magnesium is designed to be suitable from preconception through pregnancy and breastfeeding.

Magnesium contributes to normal muscle function, normal energy-yielding metabolism, normal psychological function and the maintenance of normal bones, among its other recognised roles.

If you’re pregnant and taking other supplements containing magnesium, check your combined intake and speak to your healthcare professional if you’re unsure what’s appropriate for you.

Can I take it alongside Fundamental Woman or Fundamental Man?

Yes. Fundamental Magnesium is designed to complement Fundamental Woman and Fundamental Man and can also be taken alongside our Omega-3 and CoQ10 products.

If you’re taking other supplements containing magnesium, check the combined daily amount.

Is it vegan?

Yes. Fundamental Magnesium contains magnesium bisglycinate in a plant-based HPMC capsule and is suitable for vegetarian and vegan diets.

Does it contain any fillers?

No. The formula contains magnesium bisglycinate and the plant-based capsule shell — nothing else.
