Doctor's Best is THE Best. I've taken DrB supplements for years and years. They are the best company out there and do all the necessary quality control on their products. For this particular product, they use mushroom extracts from Nammex, who is one of the leading mushroom suppliers out there. I was so exited when I learned that DrB was going to have mushroom cool! The health benefits of mushrooms are enormous and DrB is again ahead of its time.

Great Immunity Complex. Now more than ever, immune boosting supplements are a vital part of many people's routines. There are tons of different products out there making unfounded claims and adding a variety of weakly dosed, poorly researched ingredients into their supplement. This product from Doctor's Best contains a mushroom complex that is standardized for its beta glucan content. Beta glucans have been found to have various potential benefits, from improving cholesterol to stimulating the immune system. 2 capsules provide 280mg of beta glucans from Reishi, Lion’s Mane & Shiitake mushrooms. I take it daily to keep my immune system strong and so far, so good. Doctor's Best is also A brand that I trust so overall, I certainly can recommend this supplement. The value is worthwhile.

These vitamins should help boost your immune system. Because of the pandemic, I have tried many different products this year to try and boost my immune system. Doctor's Best is a respected brand of supplements, and this blend of 3 mushrooms contains beta-D-glucans, which have been shown in various studies to improve immunity. Of course you can never be sure how effective a supplement like this is, because if you don't get sick you can't be sure it was because of the vitamin you were taking or just because you managed to avoid being too close to others who were sick. But I think it's worthwhile to do everything you can improve your body's ability to fight infections, so I am sure that taking these supplements will not harm me. They can only help.
