I'm not finding a standardization percentage on my bottle nor in the description, does this have a guaranteed standardized dosage of beta glucan?

The bottle says 250 mg of the beta glucan but it is not standardized. I have used this product because I have an autoimmune disease that depresses my immunity and it does work to prevent pneumonia and other respiratory viruses. I am not sure you need a standardized dose but I usually take Swanson's Beta Right beta glucan and it works well consistently.

What are the other ingredients in this?

Beta - 1,3/1,6 -D- Glucan Powder (from Saccharomyces cerevisiae)100 mg* Maitake Mushrooms (Grifola frondosa)160 mg* Other Ingredients: Cellulose (capsule), Magnesium Stearate (vegetable source), Rice Flour and Silica.Contains No: Sugar, salt, wheat, gluten, corn, soy, milk, egg, shellfish or preservatives. Vegetarian/Vegan Product.

What does "1,3/1,6" mean?

Beta glucan is a chain of glucose sugars hooked together. Glucose has six carbon atoms in it and they are numbered 1 through six. So the bonds between two glucose molecules is either from the number 1 carbon on the first molecule to number 3 on the second molecule or from the number 1 carbon on the first molecule to the number six carbon on the second molecule. Both occur naturally and both are active immune boosters.

Why are the capsules half full, my capsules are barely half full? Is this correct are should I return them?

I would call NOW customer service. I checked one of mine and it was very full.
