I take K2 during the mid day with main meal. There are different theories on how K2 works. One says it goes to the liver and only is used if needed but don't know for sure. Nattokinase has a 3 to 8 hour window in which it is active. I take it morning and bedtime. So I just take K2 during my evening meal so outside the 8 hour windows.
My plan is to take K2 for 2 or 3 months - sort of like doing a cleansing of calcium from the arteries - then take it every second or third day dor maintenance. I'll experiment.
I would take a strong antioxidant like astaxanthin with your cod liver oil and butter. Fish oil without antioxidant protection can damage your brain.
Here is general guideline for the nattokinase
In regard to what dosage one takes with nattokinase and serrapeptase, it really depends how sick and symptomatic one is. Also age is a factor. As one ages, one can build up a lot of gunk in the arteries. Another factor is the profile of ones disease.
If your under 40 and relatively healthy, ones arteries are generally going to be in decent shape so I don't think one needs it. If one is relatively healthy and over 45, I would say 2000 FU on empty stomach before bed is all you need for preventative measure.
If one has anything related to heart disease and you are symptomatic, it means there are more serious problems going on. So probably a good idea to take higher dose just to be sure. I would dose nattokinase at dosage of 6000 FU 2X per day.
Whether one needs serrapeptase is not clear but it can't hurt and may help. PLus it works a little different than nattokinase. I'd go 80,000 IU three times a day. Take it with nattokinase. In my particular situation, I found I needed it.
You do this for 1 to 3 months. If you think you may have clots that need dissolving, it usually takes 2 to 3 months to take a lot of the clot away. Any symptoms you have should be gone within one month. For maintenance, taking 2000 FU when going to bed and upon wake. It's really ones call to decide whether serrapeptase is right for you and also length of time.
If one has cancer, i'd look into enzyme therapy also.
If one has a chronic illness then besides the aforementioned factors, you have to look at the profile of your disease. If people with your disease are dropping dead from heart disease or show any signs of blood coagulation then I would do a 1-3 month cleansing of your arteries then go on maintenance. So I'd follow what I said about heart disease and adjust it for ones age and other factors. i'd look into enzymes in general and experiment with them.
Everyone's situation can be different so the above is just some framework to operate within. you adjust it accordingly for your risk factors.
There are some rare blood clotting disorders that nattokinase doesn't treat so be careful. nattokinase can replace things like tpa, coumadin etc. It doesn't replace something like heparin. heparin by the way seems like one of the few positive prescription drugs that actually addresses the underlying problems.

After multiple thromboses, 2 heart attacks, and a stroke, I found out about it on a coronary care website.
5 weeks ago, I began with 4000 FU per day increasing to 4x 4000 FU per day for 3 weeks. Will shortly drop back to 4000 FU per day. I use alongside K2 every second day. My issues have settled, my varicose veins are noticeably less, not hard and painful anymore. ( I have had this chronic complaint for approximately 35 years.)
To say that I am impressed by the results is an understatement.
My heartbeat is still often irregular however I am seeing better results and quicker recovery times.

Glad to hear that you were able to resolve the pain in your calf using nattokinase!
There are different strengths of nattokinase. Could you tell us what strength and brand you used? Thank you!

Nattokinase Side Effects

Just thought it is worth sharing my experience with Nattokinase. Took it for a week without any other supplement, everything went fine even noticed a decline in the size of a small cyst.
Yesterday I took the supplement with Chaga mushroom, this morning I woke up and passed blood in my urine, little clots nothing major. Persisted throughout the day, went the GP they confirmed I have no infection and the GP and I both believe it is the Chaga interacting with the Nattokinase in a negative way, so I have no stopped Nattokinase and will stop all supplements for a few days to allow my body to reset.
Once this is done, I will resume with just chaga. Natto is good but make sure due to its blood thinning properties you are careful with what you mix it with.
Take care all, Joe

Then I took 200 mg of Nattokinase because it was throbbing in spite of all this and started in the middle of the night while I was sleeping, so to take all this again was a bit too much. After about 1 hr pain stopped. In the morning I had just a vague sensation of throbbing maybe 1-2 out of 10.
So I took 200 mg of Nattokinase more and NO PAIN. AND I DID NOT TAKE ANYTHING FROM THE LIST ABOVE.
I am so happy! I will continue to have Nattokinase 100 mg as a support for the next few days. I am an emergency physician myself and I can say this supplement is miraculous. In the way to replace Aspirin, but now with your post, it saved my life. Thank you.
I just read that you were taking CoQ10 and now added the Nattokinaise and it has helped your migraines. I have migraines now for 40+ years I have been taking CoQ10 for years, my question is, do you take both of these at the same time before a meal on an empty stomach? I was told to take my supplements (which we take a lot of them) after our night time meal. So that's why I'm asking. Would love to know how you are taking this. I will try anything for migraines. Thanks in advance. Ampy

Look for my posts on nattokinase by searching earth clinic "+prioris+nattokinase".
You will also find a lot of positive anecdotal reports on internet from people.

I will continue to take 1 capsule of 2,000 a day. Only side effect is that I tend to bruise more easily but that's okay.

Only taking Natto for one week it's likely it's lowered your bp 13/9 from what it would have been if you weren't on any meds.
This is why one should always take the natural supplement at least a month before starting to taper slowly off the meds while keeping close watch on bp.
Best Way to Take Nattokinase

It is my understanding that you get the best results when taken on an empty stomach because when you take it with food, the enzymes will work on breaking down any protein you have just eaten instead of the problem proteins you want it to work on.
I take it along with Serrapeptase and I leave them on my bathroom counter so I can take them when I wake up in the night to use the restroom. That way, by the time I wake up the hour has passed and I can eat my breakfast without worrying! It is great that it's working for you - it will probably work even better on an empty stomach :-)

EC: Pat, FU is the acronym for Fibrinolytic Units, which are defined as enzyme activity units specific for breaking down fibrin. If you search on Amazon for Nattokinase, you will see various brands of Nattokinase have 2,000 - 4,000 FU per capsule. More info regarding Fibrin Units in a Q&A on Amazon here.

The other thing worth mentioning is to be very careful if you take nattokinase with Advil as it may cause blurry vision. I took an advil at night a few days ago to help with muscle stiffness and the next morning my vision was extremely blurry for the most of the day. Advil can cause blurry vision (one of the listed side effects), but I have never had that before. Worth noting. Would love to hear from other's experience. Can't find much about feedback from real people about nattokinase side effects on the web.

Does anyone know how much Nattokinase to take everyday for blood thinning? I don't know whether to take 50mg daily or if I need 100mg daily? I also take VitE, Garlic and a good Fish oil but thought I should start that also! Don't want to go on Pharmaceutical blood thinners! Don't like that idea!
