Best supplements for increasing GABA?

Hey guys, I’m curious to know your list of supplements that increase GABA.
Any particular experience?
Cause apparently taking GABA orally is not really well absorb (if any at all)
Thoughts?

There will be no better than l-theanine also good form of magnesium, deficiency can lead to lower levels of GABA

GABA does in fact work. I prefer taurine as it’s milder for me.
