Sour, bitter and astringent to taste, amla's numerous health benefits are hard to get by directly eating the fruit. Instead, it is commonly consumed pickled, candied, juiced, or as a powdered extract (like that used in supplements). Amla has been used in Ayurvedic medicine for centuries to support immune, digestive, and skin and hair health.*

Frequently Asked Questions

Have been taking Serracor-NK for about 3 years now. Has definitely cut down on the excess fibrin and mucus. Can breathe so much better too. Will continue with this product indefinitely as it has greatly helped my breathing.

I’ve been using Serracor-NK for about 7 years now. The CoQ10 is great for energy and mental acuity! I’m pretty sure it’s the effect of the fibrin metabolism that supports my vision. I am 64 and still don’t wear glasses, for reading or otherwise. The magnesium support has a nice calming effect on the nerves, I find. I may get a cold every 5-6 years, but that’s it. I found out the hard way, by forgetting to pack my Serracor-NK for a trip, exactly what benefits I’m getting from this enzyme supplement. And I don’t want to be without it again! Thank you! It’s healthy in so many ways.

Serracor-NK

AST ENZYMES I believe are of top quality products. I just would like to know what the Natto mg content is per capsule.
Being it's a proprietary blend it's a guarded secret. The EXCELLACOR product has given me my hand dexterity back to an extent, & has rid my body of inflammation.

They have all the best proteolytic enzymes in it including Nattokinase which is super popular especially since Covid Times.
These are pure quality and so is the company since they manufacture them. Take them on an empty stomach...for best benefits
