Flu resistance
Most Useful Review
I often fall ill, so I decided to try zinc as an immune booster after reading about its benefits. I took it alongside Ester C for 1.5 months. Recently, I was exposed to flu, yet despite the infection in the house, I did not get sick! My son experienced a mild form of the illness, but he began taking zinc and recovered quickly. In contrast, my father-in-law, who refuses to take supplements, suffered significantly from the flu. It seems zinc truly works wonders for immunity!

Respite Vitamin A is essential for mucous membranes, so I purchased it for my husband with severe asthma. I struggled to sleep due to suffocation, but after taking 100,000 IU daily, I noticed a significant improvement within a month. His daytime cough has also decreased dramatically. However, high doses of vitamin A can result in vitamin K deficiency, so I recommend consuming natto alongside it.

Great Elder! It assists at the first sign of a cold. My daughter typically suffers from a fever and cough for a week, but when her temperature rose to 37.4, I swiftly gave her two elderberry tablets.

I suffer from a chronic stiff shoulder, which has been quite debilitating. Recently, my autonomic nervous system was disturbed, causing me to miss work.
