What is Doctor's Best Natto-Serra?
Doctor's Best Natto-Serra supports healthy immune response and supports healthy circulation. It is a combination of two natural proteolytic enzymes, serrapeptase and nattokinase. Serrapeptase (serratiopeptidase) is a protein-digesting enzyme isolated from bacteria isolated from the intestine of silk worms (Serratia E-15). The serrapeptase is formulated with Serrateric, a superior alternative to enteric coating that protects the enzyme until it reaches the intestines for optimal absorption. Nattokinase is derived from Natto , a fermented soy food popular in Japan for centuries.
How does it work?
Natto kinase is an enzyme that is found in traditional Japanese soy cheese that is also known as natto. Natto has been shown to exhibit a fibrin lytic effect in the blood stream. It has the capability to break down blood clots. Nattokinase was discovered I 1980 by a doctor from Miyazaki Medical College in Japan. Since its discovery, the cardiovascular effects of Nattokinase have been studied in many countries. Serrapeptase has other applications. Serrapeptase is an immunologically active enzyme. It can bind itself to the alpha 2 macroglobulin in our plasma where it is shielded from the immune system while retaining its enzymatic activity, and in this way it is transferred to the sites where it is needed in the body. It is this same type of specific action that allows silkworms to eat its own protective cocoon, digest it without any side effects.

Storage may be a problem
Size: 4 Panel-88‘’Wide, Color: Black
Worked as expected however storing it was not so easy. The feet did not collapse one over the other but provide privacy.

Perfect size, good privacy
Size: 4 Panel-88‘’Wide, Color: Black
This is a good divider. The dark, thick panels provide blockage from the light. Assembly was not very hard, but it wasn't simple. I ordered this product two times in the past couple of weeks. The first time I assembled it, I noticed that the picture assembly directions aren't completely accurate. The labeled parts don't match the labels on the instructions. The wrench included in my box is too big for any of the bolts or screws used for assembly. After getting the right tools and matching against the instructions, I finally got it assembled. The divider I ordered this week is missing two wheels and there is no number for calling the supplier; thus, I seem forced to return it, instead of easily getting the two wheels. Once assembled, I am pleased with the end product and I consider it a good value.

Pretty good, especially for this price point.
Color: Beige, Size: 21.5"- 1 Panel
This is merely a piece of cloth stretched between the frame borders, but it works perfectly. It arrived quickly, all parts present and in good condition. I didn't put the castors on, as it will be more or less always in one position. I simply attached some felt sliders on the bottom to prevent scratching the floor and to allow clearance for the center screw (which is not flush fit). Overall, a reasonable deal for the price point.
