"I created Myregyna® because menopause and its after effects is an enormous issue affecting millions of women. Yet we have so few options help us with it - until now!" - Dr Iona Weir


A lifetime of innovative cell biology.

Weir Science is an innovative New Zealand R&D company founded by cell biologist Dr. Iona Weir, PhD.

Dr. Weir, a scientist for 34 years, is among the few women globally patenting her research. She earned her PhD at the Cancer Research labs of the University of Auckland, discovering that the fundamental cellular process of apoptosis in plants could be reversed, later applying this to human cancer and immune cells. This led her into fields like botanical drug discovery, immune modulation, and gut health. She served as Chief Scientific Officer developing an oral drug for eczema, breakthrough gut innovations like IBSacol, Phloe, and KiwiCrush, and collaborating with major multinationals like Nestle.

Exploring cell signaling, gut health, and immunology, she saw remarkable effects on the skin. This led her to develop her patented Myrecil Ingredient behind her Atopis range of scientific skin care and dermatology, followed by her new Myregyna® postmenopausal health system.

Following her time at the Ontario Cancer Research Institute in Canada in 1999, Iona returned to New Zealand to pursue her ground breaking research into cellular renewal systems.


A breakthrough in post menopausal sexual health.

At the centre of this new approach is Dr Weir’s globally patented Myrecil®, which supports the optimisation of the cellular process of apoptosis. Myrecil®Biome – a version developed specifically for gynaecology – powers her new Myregyna® postmenopausal health system. Myrecil is so powerful and safe that as well as targeted topical usage with Myregyna Hydrating Cream, it can also be used in Myregyna Postmenopausal Dietary Supplements to support postmenopause at a systemic level. “My approach is to support your fundamental natural systems – systems that can go haywire for many reasons, such as the rapid hormonal changes of postmenopause. Once those systems are well supported, then you then just need maintenance. So that’s why I designed Myregyna to be simple, effective, and affordable.”
