Vitamin
Vitamin B6 (Pyridoxine)
B6 supports production of serotonin and dopamine, neurotransmitters that plummet during menopause, with solid evidence for improving mood symptoms and sleep quality in women with PMS. Several well-designed studies show benefits for depression, irritability, and sleep disturbances, though most research focuses on younger women rather than those in menopause. The evidence is promising enough to warrant trying food sources first, then modest supplementation if you're struggling with mood swings or sleep issues.

Overall: Mixed evidence
Randomised controlled trials
Multiple randomized controlled trials show B6 reduces depression scores and improves sleep quality, primarily in women with PMS.
Population studies suggest adequate B6 intake correlates with better mood, but results are inconsistent across different age groups.
Systematic reviews confirm B6's effectiveness for PMS-related mood symptoms, though effect sizes are modest.
Menopause-specific trials
No large-scale studies have specifically examined B6 supplementation for menopause-related mood changes or sleep disturbances.
What we do not know
Most clinical trials studied women with PMS in their 20s and 30s, not perimenopausal or postmenopausal women specifically. The optimal dose for menopause-related mood symptoms has not been established in dedicated trials. We don't know if B6 benefits extend to other menopause symptoms like hot flashes or cognitive changes. Long-term safety data for daily supplementation beyond one year is limited. The interaction between B6 and hormone therapy has not been adequately studied.
How it is used
Common dose range
25-100mg daily
Notes on dosing
Do not exceed 100mg daily long term. P-5-P (pyridoxal-5-phosphate) is the active form and better absorbed.
Get it from food first
Food sources are better absorbed than most supplements and come with co-factors that support the same pathways. If you eat two or three of these consistently, you may not need a supplement at all.
Chickpeas
1 cup
cooked, excellent source
Salmon
3 oz
wild-caught preferred
Chicken breast
3 oz
skinless, cooked
Potatoes
1 medium
with skin, baked
Sunflower seeds
1 oz
raw or roasted
Tuna
3 oz
yellowfin, cooked
Turkey
3 oz
roasted, light meat
Mediterranean diet
Rich in fish, legumes, and vegetables that naturally provide B6 along with other mood-supporting nutrients
Whole foods approach
Emphasizing unprocessed proteins and vegetables maximizes B6 absorption and retention
What depletes Vitamin B6 (Pyridoxine)
Alcohol consumption, oral contraceptives, and certain medications including some antidepressants and anti-seizure drugs can deplete B6. Processing and cooking can reduce B6 content in foods by 15-70%.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"The mood and sleep benefits seen in younger women are encouraging, and B6 is generally safe at reasonable doses. Your body needs this vitamin anyway for hormone metabolism, so focusing on B6-rich foods makes sense, with modest supplementation if food sources aren't cutting it for your mood struggles."
