Does Beta Glucan Have Side Effects?

No, there are no known side effects pertaining to our Beta Glucan. There have been numerous safe human and animal studies showing the safety of Beta Glucan. The Food and Drug Administration (FDA) has given our Beta Glucan GRAS rating, which means Generally Recognized as Safe under the Food, Drug, and Cosmetic Act. This certification is extremely hard to achieve especially when it comes to a dietary supplement.

You can take this product without worry! There have been multiple studies done on fully-healthy people looking at every health parameter you can imagine: organs, tissues, chemicals, brain function, etcetera. No harmful effects were caused at any dosage level. Even people who were taking doses that were exponentially higher than any level we recommend, (some of the more exotic animal studies have doses that exceed 800X the recommended dosage) displayed 0 side effects whatsoever. As I am famous for saying, “unless you hit somebody in the eye with the bottle, there is no harm that can be caused by this product” (A.J. Lanigan).

You can get killed by anything if you eat it by the spoonful. Anything, it’s like sand. Everything can kill you but in normal doses, ABSOLUTELY NOT. There were a few studies in ’80s coming from Japan that you shouldn’t take it together with aspirin or some non-steroidal drugs but they were never confirmed. And it seems that they had to use some particularly strange glucan which they never described in the studies, and, also a special genetically strange strain of mice which are not normally used and not fully normal. So there were a real strange, strange combination of things. They used a massive dose too. So for our body, for normal use, there is no way to harm us.
