Excellent!

Natto-Serra I can go on forever about these two ENZYMES... NATTOKINASE... 1. IS A PROTEOLYTIC ENZYME 2. IS A JAPANESE FERMENTED SOYBEAN 3. INHIBITS SARS-COV-2 ( SEVERE ACUTE RESPIRATORY SYNDROME CORONAVIRUS 2) as well as BHV-1 (BOVINE HERPES VIRUS). STUDY SHOWED that SARS-CoV-2 SPIKE PROTEIN SIGNIFICANTLY BLOCKS DNA REPAIR, YOU NEED NATTO KINASE TO COMBAT THIS!!! STUDY SHOWED SARS-CoV-2 trreated with NATTOKINASE FULLY INHIBITED INFECTION TO CELLS!!! ACE2 are proteins found on the surface of human cells, these proteins are the entry point for SARS-CoV-2 infection. the SPIKE PROTEIN binds to our ACE2 RECEPTORS. NATTOKINASE INHIBITS THIS FROM BEING ABLE TO PLACE. 4. BREAKS DOWN PROTEOLYTIC ENZYMES AND FIBRINOLYTIC ENZYMES. When you take enzymes with food, they help digest food, When you take on a EMPTY STOMACH, 2 HOURS BETWEEN MEALS, they quickly enter the bloodstream and clean BLOOD, TISSUES and ORGANS. They clean out proteins that don't belong in your BLOOD, TISSUE and ORGANS.

Honestly can’t say if it’s working as taking so many other supplements, but I know something’s doing the job against my candida. High quality as caps have lasted past best before date. Size is good. Dosage is good. Good benefits. Taste is fine. Ingredients are exactly what I wanted. Great!

I like that this gives the benefit of two quality enzymes and a single small sized capsule is enough for one day's dosage. The ingredients list looks clean and capsules are easy to swallow without taste. I bought this to clear my system of the virus after covid vaccination. My husband and I have both seen improvements in near and far sighted vision. In fact, he has completely reversed his! Also, metabolism has increased for both of us and we've lost weight, mostly fat and are able to fit into our jeans from 10 years ago. My weight is also more evenly distributed and I'm now more of an hourglass rather than a pear shape, which might be due to excess estrogen caused by a sluggish liver. Please give me a like if you find my review to be helpful for you. 🤗🙏

Good quality ingredients, enteric coated, absorbs well. Good size for the price. Dosage: I took three before each meal ( 1 hr). Neutral taste. Benefit: Mucolytic. Definitely helped clear out a past cold. Natto comes from fermented beans and Serrapeptase comes from a bacterium that helps silkworm emerge from coccoon. However, the product is animal-free. in case anyone was wondering, it is vegan.

Breathing has become easier. Something is dissolving, that's for sure. Just a few days later, it became easier for the nose to breathe, and some mucus flashed out against the background of the absence of diseases. A little, but surprised, never had this. A small scar from childhood became less noticeable. I hope something else unnecessary inside the body dissolves. I drank one capsule for the night on an empty stomach.

I am a woman who suffers with heavy menstrual cycles. I found that two ingredients within this supplement is great for women that suffer with cystic fibroids. After a few weeks of trying this, I noticed I missed your cycles aren’t as heavy. I hope to have continued success with the supplement.

Helps a tonne with long covid and ME/CFS. If you can stick through the first phase of herxing - temporarily feeling worse for about 7 to 10 days (as it breaks up micro clots and your body deals with this and what is contained inside the microclots). I have bought the larger 270 amounts of 120,000 Serrapeptase and and nattokinase (2000 fu per capsule) separately for some cost effectiveness also. I actually take around 6 capsules worth of this natto-serra (each capsule contains 40,000 fu serra and 2000 fu natto) a day (so overall this would be 240,000 fu serrapeptase and 6000 fu nattokinase) but split into two doses and both on empty stomach. For those wishing to try one at a time instead of both at once I reccomend nattokinase first before serrapeptase. I have had much improved cognition and energy with this.

I bought this awhile ago and finally started taking it a couple days ago. I don't know if it's this or just a real coincidence, but I have found I have a freakish amount of energy. I bought it for pain because I read it can help with that. It's only been a couple of days, and I am in the process of building a bunkie, so I still have the pain. But I'm just really amazed at the energy I've had for the last couple of days. Coincidence....maybe. But I'm thinking it's the Natto-Serra.

Have been doing a little experimenting with proteolytic enzymes and this has been the most effective so far. It's potent enough to do in 1 dose what others would take double or often triple. Scale of effectiveness is ease of mobility, smooth joints, less aches. I like to hit the ground running, and these two ingredients seem to deliver.

Doctor’s Best Natto-Serra is a combination of two natural enzymes that have been used as dietary supplements for decades. Serrapeptase (serratio-peptidase) is a proteindigesting enzyme isolated from the friendly bacterium Serratia E-15 discovered in the Japanese silkworm. Nattokinase also digests protein and is derived from 'natto,' a fermented soy food popular in Japan for centuries. This nattokinase is free of vitamin K. The serrapeptase is formulated with Serrateric, a superior alternative to enteric coating that protects the enzyme until it reaches the intestine for optimal absorption. Good buy!

Worked to clear my hubby's veins - his feet were blue prior to taking this medication and he always complained about his leg muscles tightening when he would walk a short distance. He would break out in sores on his lower legs and then end up in hospital with septicemia. Since taking this medication, his feet are pink and he has not been in hospital for these sores.
