Maintaining healthy blood circulation and balanced coagulation is a key part of supporting cardiovascular health. Fibrinolytic enzymes, such as plasmin, produced in the endothelial cells are responsible for ensuring proper blood flow. However, production of these enzymes decreases with age, which can result in increased fibrin levels. Nattokinase also inhibits a key enzyme resulting in arterial dilation to help maintain healthy blood pressure levels, and can generate tissue plasminogen activators helping to promote blood flow. Because it is a highly purified extract derived from soybeans, supplementing nattokinase differs from consuming soybeans in that nattokinase escapes the typical breakdown by digestive enzymes, and is absorbed and taken into the body directly from the small intestine to exert its effects in the plasma.

Nattokinase is a powerful enzyme used to support normal blood flow, circulation, and blood pressure levels. Derived from a highly purified extract of the traditional Japanese food natto, nattokinase is a natural, highly active enzyme that helps promote normal levels of fibrin. Fibrin is a filamentous protein formed in blood, which can accumulate along blood vessel walls and affect blood flow. Research has shown nattokinase closely resembles plasmin, the only endogenous enzyme that directly dissolves fibrin. It is thought to increase the body’s production of plasmin. Nattokinase has been shown to support activation of many of the body’s 3,000 endogenous enzymes. In addition, while many of the agents involved in promoting healthy blood flow and coagulation either have limitations, and or serious side effects, this formulation of Nattokinase has a potent support activity that lasts for an 8-12 hour period and is safe for long-term use. Each capsule of Nattokinase contains 100 mg of nattokinase.

Suggested Use:

1 soft gel capsule two times per day or as recommended by your health care professional.

Best I have tried
Source naturals is the best brand of melatonin that I have tried. I have been using it for years to help me stay asleep. I typically fall asleep fine, but where I run into issues is staying asleep or if I wake after a few hours of sleeping. The melatonin helps me fall back asleep faster and I feel refreshed the next morning. You will probably want to experiment with the dosage, I have found that the 5mg works best for me. And I like the peppermint flavor in lieu of the orange simply because I have usually just brushed my teeth before slipping this under my tongue.

My Most Reliable Sleep Aid
I've had issues falling asleep and staying asleep ever since I was a teenager, but for well over a decade, I've been able to count on melatonin to help me sleep better. This under-the-tongue version of it seems to work the best, being absorbed into the bloodstream. It helps get me to sleep relatively quickly while also helping significantly with keeping me asleep. I use one of these every night. I'd strongly recommend using these as well before turning to prescription sleep aids. They can also work well in conjunction with prescription sleep medicine if necessary.

This is a good product but the peppermint flavor is too overpowering
The sublingual Melatonin is ideal for traveling because it works almost instantly, so you can get to sleep faster than usual. I normally buy the orange flavored version and ended up with this peppermint one by accident (not paying attention), I found the taste much too strong and it seemed to create a burning sensation where I placed it under my tongue. I will stick to the orange version in the future.

I particularly love the sub-lingual
I've been using melatoning for yeeeears. I particularly love the sub-lingual. I use the 5 mgs and take two every night just as I go to bed and within minutes I'm asleep. I wake up rested and refreshed. Note: You have to be very patient with the dosage. Start with one..then add 1/2 a pill or another one. It works! The key is getting the exact dosage for you because we are not all the same. For example: I always take two. Very rarely I need one more, how do I know? Well, if I can't get to sleep within a reasonable amount of time I will take a third. Now, if I do this a couple of days in a row I start to wake up a little tired in the morning. Now I know I have too much melatonin in me so I may not take it the following night at all until my own body tells me it needs it.
