To Charlie,
I know this is an old post, but dermatitis is a classic sign of low arachidonic acid/prostacyclin. Theoretically, B6 would help increase AA and prostacyclin, but it doesn't help much. Chicken fat is the best source of arachidonic acid/prostacyclin, and would probably clear up your dermatitis. I know Ray Peat doesn't approve of eating chicken fat, but you might want to research this issue if you still have dermatitis. Dietary arachidonic acid, like in a rich chicken soup, is actually anti-inflammatory, as opposed to cellular arachidonic acid, which participates in the inflammatory response to free radicals, like those caused by unmetabolized vegetable oils. I think the key is to completely avoid vegetable oils. Deficiency of n-6 polyunsaturated fatty acids is mainly responsible for atopic dermatitis-like pruritic skin inflammation in special diet-fed hairl... - PubMed - NCBI
@haidut What I'm wondering is if arachidonic acid would be beneficial if trying to maximize muscle growth? I heard any anti inflammatory substances should not be taken anytime close to pre or post workout, since they can inhibit the inflammation and swelling response in the muscle tissue, which is needed to grow more muscle. Would arachidonic acid taken post workout maximize the inflammatory response, and thus help maximize muscle growth post workout?
