A recently published meta-analysis compared the treatment of ADHD with multi-nutrient supplements versus placebo.
Children received either placebo or Daily Essential Nutrients(Vit A 384 IU, Vit C 40 mg, Vit D 200 IU, Vit E 24 IU, Vit K 8 μg, B1 4 mg, B21.2 mg, B3 6 mg, B6 4.67 mg, B9 50 μg, B12 60 μg, B7 72 μg, B5 2 mg, Ca 88 mg, Fe 0.92 mg, P 56 mg, I 13.6 μg, Mg 40 mg, Zn 3.2 mg, Se 13.6 μg, Cu 0.48 mg, Mn0.64 mg, Cr 41.6 μg, Mo 9.6 μg, P 16 mg. Proprietary blend: Choline bitartrate, Alpha-lipoic acid, Inositol, Acety-l-carnitine (as acetyl-L-carnitine hydrochloride), Grape seed extract, Ginkgo biloba leaf extract, Methionine (asL-methionine hydrochloride), Cysteine (as N-acetyl-L-cysteine), Germanium sesquioxide (as chelate), Boron, Vanadium, Lithium orotate, Nickel. Other ingredients: Cellulose glycine 45 mg, Citric acid 26.814 mg, Magnesium stearate24 mg, Silicon dioxide 20 mg).
Adults received either placebo or EMP+ (Vit A 5760IU, Vit C 600 mg, Vit D 1440 IU, Vit E 360 IU, B1 18 mg, B2 13.5 mg, B3 90 mg,B5 21.6 mg, B6 36 mg, B9 1440 μg, B12 900 μg, Biotin 1080 μg, Pantothenic acid21.6 mg, Ca 1320 mg, Fe 13.74 mg, P 840mg, I 204 μg, Mg 600 mg, Zn 48 mg, Se204 μg, Cu 7.2 mg, Mn 9.6 mg, Cr 624 μg, Mo 144 μg, K 240 mg, Germaniumsesquioxide 20.7 mg, B 2400 μg, V 1194 μg, Ni 29.4 μg, Choline bitartrate 540mg, DL-phenylalanine 360 mg, Citrus bioflavonoids 240 mg, Inositol 180 mg,Glutamine 180 mg, L-methionine 60 mg, Gingko biloba 36 mg, grape seed extract45 mg).
Using the Global Assessment of Functioning (GAF) scale for adults, and the Children's Global Assessment Scale (CGAS) for children, the study team reported moderate improvements in overall functioning from the use of the supplements. GAF and CGAF are used by mental health clinicians and physicians to rate subjectively the social, occupational, and psychological functioning of an individual.
Yet no significant improvements were found for either clinician-rated or observer-rated ADHD Change Scores.
Moreover, the positive finding was compromised by a series of methodological shortcomings:
· It was just barely a meta-analysis, involving only two studies.
· The combined number of participants in the two studies was small, 173, consisting of 93 children in one study and 80 adults in the other.
· Both studies had the same lead author, Julia J. Rucklidge, who was also a member of the meta-analysis team.
With only two studies, there was no way to evaluate publication bias.
