Supplements for health 55 menopause adhd
The short version: the evidence for supplements in menopause and adult ADHD is thin, conflicted, and mostly funded by the people selling the product.
For menopause, the best-tested supplements are soy isoflavones. Multiple randomized trials show they do not reduce hot flashes better than placebo [2, 3, 4, 6]. A 2001 trial gave women 80 mg of isoflavones daily for 24 weeks and found no difference from whey protein [3]. A 2003 review put the net effect at about 10-20% above placebo, which is small enough that most women cannot tell the difference [5]. The same review found that purified isoflavone extracts do not improve cholesterol; only intact soy protein does [5]. Black cohosh, evening primrose oil, and red clover also failed in controlled trials [4, 6]. One small 2006 trial of a hop extract showed early benefit at 6 weeks that disappeared by 12 weeks [8]. The only supplement with consistent evidence for postmenopausal women is vitamin D for bone health, especially if your blood level is below 20 ng/mL [11, 14]. A 2025 trial found that UVB phototherapy plus vitamin D improved bone density more than vitamin D alone, but both groups improved [14].
For adult ADHD, the evidence is even thinner. The only controlled trial in the retrieved evidence tested omega-3 plus Korean red ginseng in children, not adults [9]. A 2012 trial of omega-3/omega-6 in children already on methylphenidate showed some behavioral improvements after 6 months, but the study was funded by the supplement manufacturer [10]. No retrieved study tested any supplement in adults with ADHD. Melatonin has better evidence for sleep disturbance in neurodevelopmental disorders, including ADHD, with one observational study showing 78% of children improved sleep [19]. But that study was not blinded or controlled.
| Supplement | Condition | What the evidence shows |
|---|---|---|
| Soy isoflavones | Menopause hot flashes | No better than placebo in multiple RCTs [2, 3, 4] |
| Soy protein (intact) | Menopause lipids | Modest LDL reduction [5] |
| Vitamin D | Menopause bone loss | Improves BMD when deficient [11, 14] |
| Black cohosh | Menopause hot flashes | No benefit in controlled trial [4] |
| Evening primrose oil | Menopause hot flashes | No benefit [4, 6] |
| Omega-3 + ginseng | ADHD (children) | Modest parent-rated improvement, manufacturer-funded [9] |
| Melatonin | ADHD sleep disturbance | Improves sleep onset and duration, uncontrolled [19] |
My call: for menopause, vitamin D is worth testing your blood level for; the rest are not supported. For adult ADHD, no supplement in this evidence base has been tested in adults at all. Confidence: moderate for the menopause negative findings (the trials are decent), low for ADHD (the evidence does not address adults).
