Source Naturals Manganese, Amino... vs Standard Process - Biost - Glute...

I have no idea what amino acids this brand is chelated with, as the bottle doesn't say. The new pill is tan in color with brown spots and a very disturbing odor. These are not possible to consume.

Sp biost is a game changer. Love 'em. It's so much better to buy through amazon, than through a distributor.

The ones on the right are the few remaining i have left. Not for me.
