I am not sure what you mean by "hire". Perhaps English is not your native language and something is lost in translation?
You seem to be asking about dosage and timing. I take a 3-6-9 blend, 1200mg, three times a day, usually with a meal. Alternately, I drink a shake with flax seed oil in it, and take just omega 3s, I think 800mg per softgel.
Taking more EFAs has definitely improved my skin over the years. Not sure about internal health as I am doing pretty well in that sense anyhow.
