You will see that one common factor in domestic abuse cases is a low level of omega 3 component DHA. This is not an excuse for violence but a possible reason for uncontrolled behaviour. It fits a pattern of other research papers which show in some cases the violence is turned on oneself See

We know that given omega 3 supplement the amount of violent events in prison or young offender institutes drops by 20% and similar reductions in disruptive behaviour occur in ADHD children if they are given omega supplements of appropriate strength.
I'm not for one moment suggesting that simply giving your abusive partner 4 portions of oily fish a week is going to change him overnight but maybe in a month or so it may make a difference. It is also the case that in order for the omega to be absorbed into the actual brain cells which communicate between the neurons, astrocytes, vitamin d has to be present. Availability of vitamin d is to some extent seasonal in that lower levels are available in the winter or if people don't go outside when the sun is shining strongly enough to synthesise vitamin d in the skin. This is why suicides tend to happen more after a run of bad weather or midwinter further north. As free sunlight is available throughout the year in the US no-one should be vitamin d deficient but previous studies have suggested that half of the elderly in the U.S. are vitamin D deficient (a serum level of 20 ng/mL or lower) as well as 35% to 40% of the younger population. So it is distinctly possible that this also applies to some adults who spend little or no time outside with their skin uncovered. It is also true that dark or black skinned people need six to ten times more exposure to make the same amount of vitamin d so they are far more prone to be deficient in both vitamin d and omega 3.
Cholecalciferol vitamin d3 tablets are cheap enough and a child under 50lbs needs 1000iu over 50lbs 2000 and adults can manage on 4000iu
For omega 3 to be effective a reasonable amount would be 2-3g of omega. So you need to look for high strength EPA and DHA and add the two figures together. Often capsules are 120dha 180 epa so that would make .3 of a g so ten of these would be needed to supply 3g It may be easier to use, as I do (for other reasons) a liquid form containing 900EPA600dha 1.5g omega in 5ml.I only have to take 2tps of this to get my 3g, much easier/cheaper than taking 10 capsules.
The experiments in the UK used 550mg of EPA and found this was effective for children however as DHA component is also necessary I would look for a supplement which supplies both if I had a difficult violent child.
