Premenstrual syndrome (PMS) describes physical and emotional symptoms that recur in the weeks before a period and improve after bleeding begins. Common experiences include mood changes, irritability, anxiety, tiredness, poor sleep, bloating, cramps, breast tenderness, headaches, skin changes and food cravings.
Recognising serious symptoms
Symptoms differ between people and from one cycle to another. When they are severe enough to disrupt relationships, work or daily life, assessment is important. Premenstrual dysphoric disorder (PMDD) is a more intense form associated with marked depression, anxiety or anger. Suicidal thoughts require immediate emergency help.
Establishing the pattern
Keeping a daily symptom record for at least two cycles is one of the most useful first steps. It shows whether symptoms consistently occur during the luteal phase and resolve shortly after menstruation, helping distinguish PMS from depression, anxiety, thyroid disease, perimenopause or another condition that is present throughout the month.
Regular exercise, adequate sleep, stress-management and a balanced diet can reduce symptoms. Some people prefer smaller, regular meals. There is no need for a universal exclusion diet, although reducing excess alcohol and noticing whether caffeine worsens anxiety, breast tenderness or sleep may be worthwhile.
If symptoms remain intrusive, a GP may discuss the combined contraceptive pill, an antidepressant—often an SSRI—or cognitive behavioural therapy. Specialist gynaecology or mental-health input may be appropriate when first-line approaches have not helped.
Useful supplements
Supplements should be selected for the individual rather than used automatically. Product directions and advice from an appropriately qualified professional should take precedence over general information.
| Supplement | Effects |
|---|---|
| Multivitamin and mineral formula | Provides zinc, vitamin C and B vitamins involved in hormone metabolism, mood, energy production and fatty-acid conversion. |
| Evening primrose oil or starflower oil | Provides GLA, which can be converted to DGLA and related compounds involved in inflammatory regulation. |
| Krill oil | Provides EPA and DHA used in signalling compounds involved in mood and inflammatory balance. |
| Hop alpha acids | Intended to reduce pain and support inflammatory balance. |
| Magnesium citrate | Supports normal hormone-related metabolism, glucose regulation and muscle relaxation. |
| Multi-strain probiotic | Intended to support bowel function and microbial processes associated with normal liver metabolism. |
| Lecithin powder | Supplies phospholipids that support normal cell membranes and liver function. |
| Chromium picolinate | Supports normal macronutrient metabolism and is intended to assist glucose regulation and cravings. |
Evidence for supplements in PMS is mixed. The NHS notes that calcium, vitamin D, magnesium and vitamin B6 may help some people, but research is limited. High-dose vitamin B6 can cause nerve damage, magnesium may cause diarrhoea, and chromium can interact with diabetes medicines. Evening primrose, krill oil and herbs may affect bleeding or interact with other treatment.
The aim is not to suppress every normal variation in mood or appetite, but to identify a reproducible cycle-linked problem and reduce its effect on daily life. A symptom diary also provides a clear measure of whether a treatment is genuinely helping rather than relying on memory during a difficult week.
