My son has ADHD and I find his behaviour improves vastly when he takes fish oil and probiotics daily (not sure which of these actually makes a difference!!) He used to be fairly happy to eat a mixture in yoghurt but won't anymore so I'm not sure how to get it in him. He won't have the chewy ones only liquid mixed in something. Any recommendations for a high quality one that won't make him gag? And how to sneak it into something to minimise the taste? Thanks!!
