About Meah Our Founder & Approved Naturopath

Hi! I'm Meah

I’m Meah, thank you for being here. You've probably found yourself here because you’ve heard great things about Fem21.

I’m the founder of Fem21 and I've been a Naturopath for over 18 years. Since 2015 Fem21 has helped over 30,000 women in Australia and Internationally.

As a woman with PCOS and mother of two, Fem21 was created from my own need to sort out my health and hormones. Also as a Naturopathic Practitioner I wanted to help as many women as possible to do the same.

I designed this beautiful blend to not only naturally balance hormones, but it also support the liver and digestive system, alkalises the body and looks after our adrenals and thyroid. I'm so happy that Fem21 has such a great reputation for supporting women's health and hormones holistically.

Real People, Real Reviews

I will say it definitely changed my hormones for the better. My period pain & symptoms decreased & the biggest thing is it almost completely eliminated my hormonal acne. It was very bad & my skin has cleared so much due to Fem21. I have the pictures if you want to see how much it changed haha. I am a big advocate for Fem21 & my friends have started using it too. I don’t know if Meah actually reads these emails or if it is an employee but I want to say thank you to Meah. Fem21 saved my face & brought back my confidence. I love that things are natural in this product. I stumbled upon the brand when I was crying one night in desperation to naturally cure my acne & found a youtube video of a girl who used your product. I listened to you talk on different podcasts too to hear your perspective. Thank you for making this product.

I just wanted to thank you so much for your product, I can’t live without it now! I had awful acne after coming off the pill and couldn’t budge it for years. I saw a naturopath for a little while and started to make a difference, but the appointments were so expensive (like $300 every two weeks 😭) it wasn’t sustainable. A friend mentioned how much she liked your product so I gave it a go and by taking it twice a day I’ve totally cleared my skin and experience hardly any hormonal mood swings around my period. LIFE CHANGING!!!
