Systematic review, 2025

Do nutritional interventions help with emotional symptoms of PMS?

Vitamin B6, calcium, and zinc consistently improved emotional PMS symptoms. Other nutrients like vitamin D, magnesium, and soy had insufficient evidence supporting their use.

Systematic review, 2013

Does Vitex (chaste tree) help PMS and PMDD symptoms?

Most studies found Vitex better than placebo for PMS. For PMDD, results were mixed: one study showed it equal to fluoxetine, while another found fluoxetine more effective. Side effects were mild.

Systematic review, 2009

Which herbs, vitamins and minerals help treat PMS?

Only calcium has good evidence to work for PMS. Chasteberry and vitamin B6 may help, but most of the 62 products people try lack proper research.

Systematic review, 2007

What treatments work for premenstrual syndrome?

Many treatments have been studied for PMS, but researchers face a major challenge: there is no standard way to measure symptom severity, making it difficult to know which treatments truly work.

Randomised trial, 2003

What treatments work for PMS and PMDD?

Several treatments work. Non-drug options include cognitive behavioral therapy, exercise, and supplements like calcium and magnesium. Many studies support SSRIs (taken daily or only before menstruation). Hormonal treatments that stop ovulation also help.

Randomised trial, 2003

What complementary and alternative medicines help with women's reproductive health issues?

Acupressure helps with pregnancy nausea and calcium helps with PMS. Vitamin B6, ginger, magnesium, chaste-tree berry, low-fat diet, exercise, and fish oil show promise but need more research.

Study, 2002

Which PMS treatments have good scientific evidence?

Calcium at 1200 mg daily and certain antidepressants have good evidence of working. Many popular treatments like vitamin B6, evening primrose oil, and birth control pills lack strong evidence. Some treatments like progesterone do not work.

Randomised trial, 2000

Which dietary supplements help PMS?

Only calcium has strong evidence from large rigorous trials. Magnesium, vitamin E, and carbohydrate supplements show limited promise but need more research. Vitamin B6 and evening primrose oil have mixed results.

Review, 2026

Can diet and nutrition help reduce PMS symptoms?

Yes. High intake of calcium, magnesium, vitamin D, and vitamin B6 reduce PMS symptoms. A high-fiber, low-sugar diet with omega-3 fatty acids also appears helpful.

Review, 2025

Do yoga and dietary changes help with PMS symptoms?

Yes, both yoga and specific dietary supplements improve PMS symptoms and quality of life. Combining yoga and diet changes together appears to work better than either alone.

Survey study, 2025

Do certain nutrients and body weight affect PMS?

Yes. Higher energy intake and fat intake were significantly related to PMS, as was abnormal body weight (both underweight and overweight). Other nutrients tested were not significantly related.

Study, 2024

How do lifestyle factors like diet, exercise, and stress affect menstrual health and PMS?

Lifestyle factors significantly affect menstrual health and PMS. A balanced diet with adequate vitamins, regular exercise, good stress management, and healthy weight can reduce PMS symptoms, while poor nutrition, high stress, extreme weight, and substance use make them worse.

Review, 2023

Can diet and vitamins help reduce PMS symptoms?

Calcium, magnesium, vitamin D, B vitamins, and herbal supplements appeared helpful for PMS in studies. However, researchers say the evidence is not strong enough yet for doctors to officially recommend them as treatment.

Review, 2023

Can herbs and supplements help with PMS symptoms?

Herbs like chaste berry and supplements like calcium and magnesium may help with PMS. Evidence is strongest when combined with lifestyle changes and therapy, though more research is needed.

Case-control study, 2022

Are zinc and antioxidant levels different in women with PMS?

Yes. Women with PMS have lower zinc and antioxidant levels than women without PMS. Antioxidant levels appear linked to diet, particularly intake of antioxidant-rich foods.

Survey study, 2022

Do vitamins and minerals help reduce PMS symptoms?

Some vitamins and minerals appear to help reduce PMS symptoms, including vitamin E, B6, D and minerals like magnesium, zinc, and calcium. These findings come from reviewing studies published between 1980 and 2020.

Cohort study, 2020

Are calcium and magnesium levels lower in women with PMS?

Yes. Women with PMS had significantly lower calcium (8.3 vs 9.1 mg/dL) and magnesium (1.5 vs 1.9 mg/dL) levels compared to healthy women.

Randomised trial, 2020

Does whole body vibration work as well as resistive exercise for PMS symptoms?

Yes. Both whole body vibration and resistive exercise significantly reduced PMS symptoms, and they worked about equally well in this study.

Survey study, 2019

Do women with PMS have different nutrient levels than healthy women?

Yes. Women with PMS had significantly lower vitamin D levels than healthy women. Other minerals tested showed no significant differences. However, this does not prove that low vitamin D causes PMS.

Systematic review, 2019

Is low magnesium linked to premenstrual syndrome?

No clear link was found between magnesium levels and PMS overall. Studies outside the United States found lower magnesium during the luteal phase in women with PMS, but the practical significance is unclear.

Systematic review, 2017

Does the herb chaste-berry (Vitex agnus-castus) really reduce PMS symptoms?

A pooled analysis of 14 trials found a large average benefit of chaste-berry over placebo for PMS symptoms, but the underlying studies had a high risk of bias and very inconsistent results, so this cannot be taken as a firm conclusion.

Case-control study, 2013

Does eating more minerals help prevent PMS?

Women eating more iron had lower PMS risk, but women eating more potassium had higher risk. This suggests some minerals might help prevent PMS, but the evidence was mixed.

Randomised trial, 2012

Do magnesium or vitamin B6 reduce premenstrual syndrome severity?

Both magnesium and vitamin B6 significantly reduced PMS symptoms more than placebo, with B6 being most effective.

Survey study, 2012

What treatments help menstrual migraine and PMS symptoms?

Several treatments have evidence including triptans, NSAIDs, magnesium, phytoestrogens, and certain birth control pills. More research is needed to compare treatments.

Randomised trial, 2010

Do magnesium and magnesium plus vitamin B6 reduce PMS severity?

Yes. Both magnesium and magnesium plus vitamin B6 reduced PMS symptoms. The combination of magnesium and B6 worked better than magnesium alone or placebo.

Randomised trial, 2006

Which dietary supplements and herbs work for PMS?

Calcium and vitamin B6 have the best evidence for PMS. Evening primrose oil and magnesium have conflicting results. Other supplements like Vitex need more and better research.

Randomised trial, 2002

How well does magnesium supplementation reduce premenstrual symptoms?

Unexpectedly, the placebo (sorbitol) worked better than magnesium at any dose. Sorbitol reduced anxiety-related and total symptoms more than all three magnesium doses, suggesting sorbitol itself has an effect specific to women with PMS.

Review, 2001

What is the best treatment approach for PMS and PMDD?

About 5 percent of women have premenstrual symptoms severe enough to affect their daily lives. Start with lifestyle changes, then serotonin-based antidepressants if needed, preferably taken during just the luteal phase.

Randomised trial, 2000

Does magnesium and vitamin B6 together help with anxiety-related premenstrual symptoms?

A combination of 200 mg magnesium plus 50 mg vitamin B6 daily showed a small benefit for anxiety-related symptoms like nervousness and mood swings. Individual supplements alone did not work.

Review, 2000

Can calcium and vitamin D help with PMS symptoms?

Calcium supplementation effectively alleviates most mood and body-related PMS symptoms according to clinical trials, and women with PMS may have calcium regulation problems. However, this review does not provide specific trial details.

Randomised trial, 2000

What non-antidepressant treatments might help PMS?

A study of 466 women found calcium was effective at reducing emotional, behavioral, and physical PMS symptoms. Cognitive therapy, light therapy, and tryptophan also showed promise in early trials.

Randomised trial, 1998

Does 200 mg magnesium daily help premenstrual symptoms?

Yes, but only for fluid retention symptoms like bloating and breast swelling, and only during the second month of treatment.

Study, 1998

Does diet and supplements help PMS?

Yes, some dietary changes and supplements may help PMS. Magnesium and vitamin B6 are helpful for some women. Results usually appear after 3-4 months.

Randomised trial, 1997

Does a yeast-based dietary supplement reduce PMS symptoms?

Yes. By 6 months, the yeast-based supplement (Sillix Donna) reduced symptom scores to 18% of baseline levels, much more than placebo which reduced them to 73%.

Randomised trial, 1993

Do women with PMS have different hormone and chemical levels, and do essential fatty acids change them?

Hormone and chemical levels were mostly the same in PMS and healthy women, except aldosterone was lower and cholesterol higher in PMS. Essential fatty acids did not change any of these levels.

Randomised trial, 1991

Does magnesium supplementation help premenstrual mood changes?

Yes, magnesium significantly improved mood-related PMS symptoms and overall PMS scores in women taking it during the premenstrual phase.

Case-control study, 1988

Do women with PMS have vitamin or mineral deficiencies?

No. The study found no difference in vitamin and mineral levels between women with PMS and healthy women, so deficiencies probably do not cause PMS.

Randomised trial, 1985

Does vitamin B-6 help premenstrual tension?

No. Vitamin B-6 at 100 mg daily was no better than placebo for relieving premenstrual tension.

Randomised trial, 1983

Does evening primrose oil help premenstrual syndrome?

Yes. Studies found evening primrose oil highly effective for depression, irritability, breast pain, and fluid retention. The strongest evidence comes from 3 double-blind controlled trials.

Survey study, 2026

Does PMS affect how well young women sleep?

This study set out to check whether premenstrual syndrome is linked to poorer sleep in women aged 18 to 25, but the text available here only describes the background and methods, not the actual results, so no clear answer can be given from what is provided.

Survey study, 2026

Can changing your diet help with period and PMS symptoms like fatigue, mood swings and bloating?

This paper suggests certain foods may help, but it is not a real study on people, it is a write-up of general nutrition advice based on a newspaper health article, so it does not prove anything.

Study, 2026

How can lifestyle changes help reduce premenstrual syndrome?

Most women (75%) experience some premenstrual symptoms, but about 10% have severe symptoms. Exercise, diet changes, sleep, and stress reduction can help manage PMS.

Randomised trial, 2026

Does a multinutrient supplement reduce premenstrual and menstrual symptoms?

The supplement appears to reduce symptom severity and duration, with 88% of women reporting reduced symptom severity by the third cycle. However, this pilot study lacked a placebo control group, so we cannot be certain the supplement itself caused the improvement.

Randomised trial, 2025

Does dark chocolate help exercise performance and muscle pain during the premenstrual phase?

Dark chocolate significantly improved exercise performance and reduced muscle soreness during the premenstrual phase in female CrossFit athletes. The study was very small and limited to trained athletes, so results may not apply broadly.

Randomised trial, 2025

Can nutrients help PMS by regulating multiple body systems?

The paper proposes a theoretical framework suggesting nutrients could work across brain, hormone, blood vessel, and metabolic systems to help PMS. No evidence is presented. This is a conceptual proposal requiring clinical trials.

Study, 2025

Could ginkgo biloba, soy, and other nutrients help hormone-related mood problems like PMS and PMDD?

This paper presents a theoretical model suggesting ginkgo biloba, soy isoflavones, and supporting nutrients might together support hormone, blood vessel, and brain chemical balance in conditions such as PMS and PMDD. It is not a new study in women, so we cannot know how well it works.

Survey study, 2025

Does PMS affect how well female martial arts athletes perform?

Yes. Most female martial arts athletes experienced severe PMS symptoms, and PMS significantly affected their sports performance, though most still achieved adequate performance levels.

Study, 2025

Could taking a combination of vitamins and minerals help with PMS and PMDD symptoms?

This paper proposes a theoretical framework linking low or borderline vitamin and mineral intake to many health problems, including PMS and PMDD, but it is not a new study testing a supplement in women, so it cannot tell us how well any particular combination actually works.

Review, 2025

Does nutrition affect PMS and menstrual cycle regularity?

Yes, good nutrition supports regular periods and helps PMS, especially anti-inflammatory diets with magnesium, vitamin B6, and vitamin D. More research is needed for specific dietary guidelines.

Survey study, 2025

Do zinc, copper, and magnesium help PMS?

These minerals affect mood regulation and appear to work through similar pathways as PMS. However, the review does not provide clear evidence that supplements help PMS symptoms.

Case report, 2023

Does a combination of maca, progesterone, and magnesium help PMDD symptoms?

One woman improved significantly in headaches, cramping, menstrual flow, and psychiatric symptoms within three months. This is one person's experience, so we can't be sure others would benefit.

Survey study, 2023

Are low levels of magnesium, calcium, or vitamin D linked to PMS?

No. Although most students had low intake of all three nutrients and 69% experienced mild PMS, no statistical connection was found between nutrient intake and PMS symptoms.

Non-randomised trial, 2023

Does a supplement with Vitex, vitamin B6, and magnesium reduce PMS symptoms?

Yes. The supplement was more effective than standard therapy alone at reducing PMS symptoms and improving quality of life, with the best results when combined with standard treatment.

Case-control study, 2023

Does diet and stress affect premenstrual syndrome symptoms?

Yes. Energy intake, certain types of fat, vitamin B6, calcium, magnesium, and psychological stress were linked to PMS symptoms. Protein and carbohydrate were not.

Case report, 2023

Can maca, alfalfa, and magnesium help with PMS, period pain, and heavy bleeding?

One woman taking these supplements for four months experienced relief of her PMS symptoms, period pain, cramping, and heavy bleeding. However, this is just one person, so we cannot be certain these supplements caused the improvement.

Case report, 2023

Does acupuncture combined with supplements and meditation help PMS?

A 36-year-old woman with long-standing PMS saw major improvement in her symptoms after combining acupuncture treatments with several supplements and daily meditation. However, this is just one case, so we do not know which parts of the treatment helped most.

Lab study, 2022

Do women with PMS have different levels of calcium and magnesium in their blood?

Women with PMS had no clear difference in calcium levels in the blood compared to women without PMS, but they had a clear difference in magnesium levels.

Non-randomised trial, 2022

Does eating papaya help premenstrual tension syndrome?

We cannot tell if papaya helps because the abstract does not report the actual results. The study was small and not properly randomized.

Survey study, 2022

Are calcium and magnesium levels lower in women with PMS during the luteal phase?

Yes. This small study found that both calcium and magnesium were significantly lower in women with PMS during the luteal phase, though calcium mostly stayed within the normal range.

Non-randomised trial, 2022

Does eating red spinach pudding reduce PMS and painful period symptoms in teenage girls?

In this small Indonesian study, girls who ate red spinach pudding had a bigger drop in PMS symptom scores than girls who did not, and the difference was statistically significant, but the study was small and not randomized.
