Very impressive product. I take one capsule a day and it strengthens my body, in case I start feeling something, I also take another one at noon. The people around me caught Covid/flu but it passed me by and didn't affect me.

I bought it as soon as I tested positive for Covid. Compared to what I hear, I had a mild case. Afterwards, with all the infections and type A flu that the child brought home, I only developed a slight cough. It probably does what it promises (I also take vitamin D and spirulina). However, because I asked before buying it, it requires caution because it is immune-stimulating (if there are autoimmune conditions, it is better to ask one's doctor because astragalus root stimulates/increases symptoms).

For immune system reinforcement, it gets the job done, it has helped me a lot for two years now, take it with food in the morning or afternoon and not at night.

It does what it says. As soon as I feel like I have a cold, I take 2 capsules for 2-3 days and I also take echinacea and any symptom stops

I caught a cold and it went down to my upper respiratory system. I took this vitamin for 4 days and I got better! I will update after 1 month. I took about 35 pills continuously and sometimes 2 times a day. They do an amazing job and I am thrilled with the result (COVID-19), unfortunately, I experienced irregular heartbeats and it was because of this. It didn't happen to me in the first few days of use.

In my case, it helped me completely. I used to get sick even in ideal conditions. After many years of using corticosteroids and cold and flu medication (as always suggested by doctors), I realized that I was treating the symptom rather than the cause. So, I decided to approach the issue more holistically. My immune system was deeply depleted. I would catch a cold at the slightest exposure, even with a short swim in the sea during the summer. In Chinese medicine, my condition indicated chronic internal cold and lung dysfunction. The combination of herbs in this supplement is ideal for my case. It has been 2 weeks since I started taking it and I haven't gotten sick for a second, and what I believed to be allergic rhinitis hasn't appeared since then. If you think that a 2-week period is too short to judge, let me tell you that I was used to catching it every 3 days.
(What I have written is not medical advice, it is my personal experience and perspective on what I am dealing with.)

I am a fan of TerraNova in general. I regularly take this specific product (October-May) because it really boosts my immune system. I change it every 3 months so that my body doesn't get used to it, but I always come back to this one!
