Most fertility supplements take 3-6 months to show noticeable benefits. This is because egg development and hormone regulation work in roughly 90-day cycles. Ingredients like CoQ10, myo-inositol, vitamin D and methylfolate need time to build up in the body and support egg quality, cycle regularity and overall fertility.

However, every woman is different and results vary based on age, health and nutirtional deficiencies.

We recommend you take The One™ for 3 - 6 months before your try to conceive and during the critical first trimester.

Yes you can, follow the advice of your doctor if they have recommended you take high dose folic acid 5 mg.

The One™ already contains the recommended daily amount of active folic acid (Methylfolate 400 micrograms). Taking both together isn’t harmful, but may be more folate than you need. As folate is water-soluble, your body will excrete what it doesn’t need.

The One™ is formulated with nutrients commonly recommended during IVF, ICSI and egg freezing, including CoQ10, vitamin D and methylfolate.

Many fertility clinics encourage women to take supplements that support egg quality and nutrient status during treatment.

However, every IVF protocol is different, so we recommend sharing the ingredient list with your fertility specialist to ensure it fits your personal treatment plan.

The One contains methylfolate (5-MTHF) - the active, bioavailable form of folate. This is the form the body uses directly and is often preferred over folic acid, particularly for fertility, pregnancy and women with MTHFR gene variations. The dosage is in line with NHS pregnancy recommendations.

Yes - you don’t need to be trying to
conceive to take The One™.

The On™ is designed to support women’s
reproductive health to help proactively support egg quality as they get older
(even if not ready for children yet). Many of The One™ nutrients work best when taken consistently over time and can help support cycle health, energy and overall reproductive wellbeing.

It’s suitable if you’re planning
ahead, thinking about fertility in the future, or simply want to optimise your
egg health before you’re ready to try.

The One™ is already a comprehensive, science-backed supplement, so taking an additional multivitamin may be unnecessary and could lead to nutrient overlap (for example too high vitamin D, or B vitamins). 

If you are already taking a multivitamin, we recommend: 

- Checking for duplication of key nutrients

- Or using The One™ as your primary daily supplement while trying to conceive

- If unsure, your healthcare professional can help tailor this to your needs.

In many cases, yes. The One™ contains iodine and selenium, which contribute to normal thyroid function.*

However, if you have a thyroid condition such as hypothyroidism, hyperthyroidism, Hashimoto's or Graves' disease, or if you are currently taking thyroid medication, we recommend speaking to your doctor or pharmacist before starting any new supplement.

💡 Tip: Supplements are generally best taken several hours apart from thyroid medication.
