I have been taking this for about 5 months now, and it has absolutely improved my resistance to getting sick. My girlfriend has had 3 bad colds in the past 6 months, and I have for the most part resisted 2 out of the 3.
It works for me. Good price, no surprises. I like the combination of mushrooms and the strength.
I have been using this product for over a year, and, so far, I feel like my immune system has been improved very much.
All I can say is this, I started taking these a couple of years ago and havent even caught a cold since I started. I cant prove its because of these mushroom supplements.
In the time of flu and Covid we need all the help we can get and this is better than most. 100% natural and working. Because I don't remember when was the last time I had a flu. No flu shot needed. At least not for me.
