Why these ingredients?

CoQ10 (Ubiquinone)
Supports cellular energy production — a key process involved in egg health.
Levels naturally decline with age, which may impact how efficiently eggs function.

Vitamin D3
Plays a role in hormone regulation and overall reproductive health.

Methylfolate (L-5-MTHF)
The active form of folate, supporting DNA synthesis and normal cell division — essential during early development.


Formulated at higher-strength levels than most formulations, with a focus on what matters most.

Core 3 has been an excellent product from start to finish. From the initial communication about the product being sent out to its timely arrival, everything has been handled so professionally.

The packaging was excellent, and I really liked how the bottle was presented. The tablet is easy to take and, most importantly, has been very gentle on my stomach. I’ve also been very happy with the effectiveness of the product.

The owner has been incredibly responsive and helpful, answering any questions I’ve had and keeping me informed throughout the process. It’s clear that a lot of thought has gone into both the product and how it is presented and marketed.

Overall, I’m extremely happy with my experience and would definitely recommend Core 3. A great product, excellent communication, and a business that genuinely cares about its customers.

I’ve been genuinely so impressed with Core3.

I’m usually quite reactive to supplements because I have MCAS, so I’m always cautious when introducing anything new. Core3 has been incredibly gentle on my stomach and I’ve had no issues taking it, which in itself has been a huge positive for me.

Since adding Core3 into my routine, I’ve also noticed a real improvement in the regularity of my cycle. Obviously everyone is different, but this is the only change I’ve made recently, so it’s been really encouraging to see.

It’s so refreshing to find a fertility supplement that feels well thought out, easy to take and actually agrees with me. I’ll definitely be continuing with it and would happily recommend Core3 to anyone looking to support their fertility and cycle health.

I rarely write reviews but I feel duty bound to do so here. First of all, Dr Parveen, wow, to have gone through what you did, and turn it around into what you have, speaks volumes as to the woman and doctor you are. From the guides to CORE3, you've built something you should be truly proud of. And side note, what sorcery have you done with this supplement? It's so easy to take and is tasteless. Love, Jen x

So glad I ordered from you doc. Was literally paying almost double this amount for procieve which doesn’t even have a high dose of coq10 and now I’m so angry that I only just learnt this. Omg the capsules are so easy to swallow and no taste at all. So far so good. Really really happy and will be reordering. Praying I get my rainbow soon
