So, anecdotally, both my kids had allergies and myself, all three of us lost our allergy completely or sensitivity to a large extent within 1 year of daily supplements, no other known variable,
One got over egg allergy the other cat allergy, I had cat allergies for years. So we got a cat.
I used to seasonally suffer skin eczema where my hands would peel and covered in itchy bumps, rare occurrence now.
Brain function, my one child used to suffer fight or flight anxiety, always fight for some reason, which stopped in the early teens to being the coolest cucumber in the room most often, so puberty or fish oil benefit? who knows.
The other, no obvious effect.
Fish burps, yeah, I buy the smaller ones which say no fishy aftertaste.
