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!

My honest review! Instead of purchasing cough syrup, I recommend castor oil. Compresses made with honey, flour, and castor oil relieve my chronic cough overnight. Also, castor oil is perfect for massaging newborns; it instantly alleviates colic. This golden oil has numerous benefits and is our family's top choice.

Improved chronic cough
Most Useful Review
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. By evening, her temperature increased to 38.6, and I administered another tablet. The next day, her temperature was 37.2, and she continued taking three tablets a day. By the third day, she fully recovered without any cough or runny nose! I’m convinced that elderberry helped.
