We conducted a 12-week study to explore the effects of selenium supplementation on flu immunity in healthy adults aged 50-64. Participants were divided into groups receiving different selenium doses or no selenium at all.
The results indicated that selenium could have both positive and negative impacts on immunity against the flu vaccine, influenced by the amount and type of selenium consumed. This complexity highlights the need for careful consideration of the benefits and risks associated with selenium supplementation in boosting flu immunity.

We are a large family (and because of cost, we are only taking half dose, 1 pill per day). We added this to our winter regimen this year. It's March first and we haven't had a sniffle. We were surrounded by people, many sick with flu at large organised events, and we even had guests in our home recovering from the flu. We'll finish this winter on this supplement and add it again next year. I'm very impressed!

Flu protection effective

My Naturopath advised me about "cell changes" on my spleen and an old brain injury due to a car accident. I was instructed to take three tablets twice a day for 90 days, and during my next check-up, there was significant improvement in both areas. While many around me fell ill with the flu virus, I have remained healthy by taking two tablets daily for the past three weeks. I complement this with vitamins, minerals, and good omega oils throughout the year.

Not as good as expected for the price! I still became ill with the flu after taking them for over three weeks! For the cost, you'd anticipate better results. I saw none and will not buy this product again!

Flu-free experience
Remarkably, I haven’t had the flu since starting this product six months ago. It’s an excellent value for everything included and allows me to avoid hunting for mushrooms in various brands. It also energises me significantly.

No flu since

Since I started taking this supplement years ago, I haven’t caught any colds or flu. The inclusion of Selenium in the dosage seems beneficial for health, and studies indicate it may reduce cancer risks significantly. It seems a worthwhile addition to my routine.

Effective immune support
This product works like magic for me. I've always had immune issues and have tried many mushroom products, but this one is significantly better. It has helped with my allergies and remarkably aided me when I came down with the flu.
