If I were to choose only one supplement it would be this versatile supplement.. effective for pain, inflammation, anxiety, fatigue, cramps or pretty much anything .. or I if get a feeling cold/flu is coming. I once had a cough for weeks after mold exposure because I ran out of it. Not even nattokinase could help. Only when I got serrapeptase it stopped

It immediately stopped a friend's tooth pain requiring root canal surgery

Worked for another's recurrent cold like magic

Long term, it should help with protecting your arteries, breaking up adhesions and keeping you healthy

It's not for everyone though, some get bad reactions (digestive issue, palpitations or anxiety) for even a portion of the capsule.

I used to take two pills a day and sometimes more (of 250kIU). Now, only taken when needed
