Started taking The One every day for 90 days after I had a miscarriage and feel it contributed to us getting pregnant. Definitely recommend.

I started taking The One as it contains all the vitamins in one supplement. I used to take 2-3 separate ones but I switched as its easier and more convenient.

I’ve tried a few different supplements, but this one doesn’t give me a tummy ache. So far, I like it and would recommend.

I have pcos and after taking The One for about 15 weeks I feel it has made a difference to my mood, food cravings, bloating and helped me ovulate a bit more regular (although still not completely predictable). I will continue to use.

I started The One about 4 months ago when we were trying to conceive and we have recently just found out we are pregnant! 🙏🏻

I switched to The One after other supplements didn’t suit me. I took it when I found out I was pregnant and I haven’t had any issues.

I have been struggling with my pcos symptoms for years but more recently with my periods. I’m not trying right now but want to sort my periods out first. The One has helped with my PCOS symptoms already and I feel happier being on it generally. Thank you!

Got Questions?

How long does it take The One to work?
+
-

Most fertility supplements take8–12 weeksto show noticeable benefits. This is because egg development and hormone regulation work in roughly90-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 months before your try to conceive.

Can I continue taking this when I’m pregnant?
+
-

Yes our 3 in 1 supplement is designed for preconception, pregnancy and postpartum.

Can I take these if I have PCOS?
+
-

Yes, The One is precisely designed for patients with PCOS with ingredients like Myo-Inositol, NAC and Vitamin D3 are specifically shown to improve ovulation in women with PCOS.

Can I take this alongside my 5mg folic acid supplement?
+
-

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.

Is The One safe to use during IVF treatment?
+
-

The One is formulated with nutrients commonly recommended duringIVF, 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.

Does The One contain folic acid or methylfolate?
+
-

The One containsmethylfolate (5-MTHF)— theactive, bioavailable formof 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 withNHS pregnancy recommendations.

I’m not trying to get pregnant right now, can I start taking The One?
+
-

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

The One 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 but want to plan for the future). 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.

Can I take this alongside my multivitamin?
+
-

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.

Can I take this if I have thyroid issues?
+
-

In many cases, yes as The One contains iodine and selenium which are important for production and regulation of the thyroid hormones. However if you have hypothyroidism, hyperthyroidism, Hashimoto’s, Graves’ disease, or if you are taking thyroid medication, its recommended to speak to your doctor before starting new medication. 

💡 Tip: Supplements should usually be taken several hours apart from thyroid medication to avoid absorption interference.

Can I take this if I am under 30?
+
-

Yes -  The One is suitable for Adults under 30. The ingredients are designed to support egg quality and support cycles, whether ou are trying to conceive, planning ahead or want to proactively support your egg health. 

The One supports foundational reproductive health, not just age-related fertility decline.
