A capsule containing fatty acids can help to lift the monthly symptoms of pre-menstrual tension (PMT), research has shown.

The supplement significantly reduces PMT's emotional and physical effects which regularly blight the lives of millions of British women and their partners, said researchers writing in the journal Reproductive Health. Women taking the two-gram capsules for six months reported their symptoms becoming far milder than they were before.

PMT affects between 80 per cent and 95 per cent of women of reproductive age, a third of whom suffer disruption to their routine activities. The symptoms typically strike 10 to 12 days before a woman has her period.
