There are many alternative treatments promoted for ADHD, but only a small number have consistently shown benefits in classroom settings. The Australian ADHD Professionals Association (AADPA) guidelines highlight that approaches such as omega-3 supplementation and reducing certain food additives have the strongest evidence base among non-medication options.
Research has shed light on the significance of omega-3 fatty acids in the diet of children diagnosed with ADHD. Studies conducted by researchers at Oregon Health & Science University have indicated that children with ADHD tend to have lower blood levels of omega-3s compared to their peers without the disorder. Specifically, their blood levels of omega-3s are, on average, 38 percent lower. Furthermore, lower levels of DHA, a type of omega-3, have been associated with increased defiance, hostility, mood swings, and learning difficulties in school-age children.
Supplementation with omega-3s has shown some results in easing hyperactivity among children with ADHD. Analysis of data from multiple studies has consistently demonstrated that supplementing the diet with omega-3s can lead to a reduction in hyperactivity, as reported by both parents and teachers. This suggests that omega-3 fatty acids can offer a small benefit to some children.
DHA Dose Range:
The studies included in the meta-analysis used DHA doses ranging from 2.7 mg to 640 mg per day. Effective doses typically included 120–640 mg of DHA daily, often in combination with EPA.
Combination with EPA:
DHA is commonly combined with EPA, another omega-3 PUFA. The combined doses of EPA and DHA showed the best results for ADHD symptom management, with EPA doses above 500 mg/day being particularly effective for hyperactivity symptoms.
Key Considerations:
Although higher doses of DHA (e.g., 480–640 mg) were used in some trials, the majority of studies also included EPA, highlighting the importance of a balanced EPA/DHA formulation.
In addition to omega-3s, there is evidence suggesting that avoiding certain food additives may also be beneficial for some children with ADHD, particularly those with existing food sensitivities. Specifically, research has highlighted the potential impact of certain food colourings, including tartrazine (lemon yellow) (102), quinoline yellow (104), sunset yellow FCD (110), carmoisine (red) (122), ponceau 4R (red) (124) and allura red AC (129). While the effect may vary from child to child, a small group of children may experience reduced irritability by avoiding these additives.
