Premular is used for the symptomatic relief of premenstrual syndrome (PMS).

About Premular

Premular is a natural medicine clinically proven to relieve PMS symptoms including irritability, anger, altered mood, headache, bloating and breast pain and tenderness.

Premular contains an exclusive extract of Vitex agnus-castus (Chaste tree) known as Ze 440 which has been the subject of multiple clinical trials. Evidence from these trials shows that Premular offers significant relief of PMS symptoms over a 3 month period, and lasting relief for 3 cycles after therapy has ceased.

Premular works by modulating hormones and neurotransmitters involved in the menstrual cycle which are linked with symptoms of PMS.

With its easy one-a-day dose, Premular is convenient to take and has been used by millions of women worldwide.

This medicine is well tolerated and non-habit forming.

Ask your health professional if you have any questions about why this medicine has been recommended for you. Your health professional may have recommended it for another reason.
