These seem to be working fine I think, haven’t taken them for long enough to know for sure, but what I have had happened a few times is when taking them they get stuck down low in my throat where I can just barely tell it hasn’t gone all the way down no matter how much I drink it down with or eat a couple of berries and then within 30 minutes I will burp and the powder comes up my throat and sinuses. It really irritates my tonsils and they swell up for a while. Was super unpleasant, but I’m not sure if it is just me or if the capsules that cause this.
