Product Safety ImunoBran® MGN-3

Product safety is paramount for any supplement.

ImunoBran® MGN-3 is one of the safest supplements on the market today, with a clinical track record of nearly 15  years. It is non-toxic (LD50 >36.0g/kg) and is well tolerated. What is more, it does not have an unpleasant taste or smell, making it an easy food supplement to take. 

Despite the fact that mushroom enzymes are used in the breakdown of the rice bran to make the product, the finished product is well tolerated even by those with mushroom intolerances.


The only (and obvious) contraindication for ImunoBran® MGN-3 are with individuals taking immunosuppressant drugs. Obviously you won't want to boost the immune system if your doctor is trying to reduce your immune system. Apart from that, ImunoBran® MGN-3 is not specifically contraindicated with any other drug or supplement. However, we do advise that you always check with your doctor or practitioner.
