The short answer is no. Beta Glucan Plus is extremely safe in the specific amounts that were added to this product. When taking the Suggested Use, it is very safe even with other drugs, medications, supplements, etc.
In situations where surgery or an operation is necessary, it is best not to take high doses of Beta Glucan Plus, due to some ingredients having blood thinning properties. However, the Suggested Use dose is still extremely safe in this scenario.
