Supplement
Alpha Lipoic Acid
Alpha-lipoic acid shows solid evidence for improving insulin sensitivity and supporting nerve health, particularly in the 300-400mg range. Most studies have focused on people with diabetes, but the metabolic benefits may help with energy and blood sugar stability during menopause. Evidence for direct fatigue relief is limited, though improved glucose metabolism could support more stable energy levels.

Overall: Mixed evidence
Randomised controlled trials
Multiple randomized trials show alpha-lipoic acid improves insulin sensitivity and glucose control, primarily in people with diabetes or prediabetes.
Some observational studies suggest associations with reduced oxidative stress markers, but findings are inconsistent across populations.
Meta-analyses confirm modest but consistent improvements in glucose metabolism and insulin sensitivity with 300-600mg daily doses.
Menopause-specific trials
No studies have specifically examined alpha-lipoic acid supplementation in menopausal or postmenopausal women for hormone-related symptoms.
What we do not know
No studies have specifically tested alpha-lipoic acid in healthy menopausal women experiencing metabolic changes. The optimal dose for menopause-related insulin resistance has not been established. We don't know if the timing of supplementation (with or without meals) affects absorption in postmenopausal women. Long-term safety data beyond 6 months is limited for doses above 400mg daily. Most fatigue studies were done in people with existing medical conditions, not healthy women experiencing menopause-related energy changes.
How it is used
Common dose range
300-600mg daily
Notes on dosing
R-ALA is the biologically active form. Take away from meals for best absorption. Can lower blood sugar.
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.
spinach
1 cup cooked
richest vegetable source
broccoli
1 cup
good source when eaten raw or lightly steamed
organ meats
3 oz
highest concentrations but amounts still very small
red meat
3 oz
small amounts, better absorbed than plant sources
Mediterranean diet
rich in vegetables and healthy fats that support antioxidant absorption
Low-glycemic eating
may work synergistically with alpha-lipoic acid for blood sugar control
What depletes Alpha Lipoic Acid
High blood sugar levels increase the body's demand for alpha-lipoic acid. Chronic stress and inflammation may also deplete antioxidant reserves. Alcohol consumption can interfere with antioxidant recycling pathways.
Interactions and cautions
No significant interactions noted at recommended doses.
Rose bottom line
"If you're dealing with blood sugar swings or metabolic changes that started with perimenopause, alpha-lipoic acid has legitimate science behind it for insulin sensitivity. The evidence isn't specific to women like us, but the biological pathways are the same. Start with food sources and consider supplementation if metabolic support is your primary goal."
