Excellent in preventing colds and flu.
The product arrived fast and was not taxed. Obviously I bought it within the limit. This product is great ... It has great value for money. In the Brazilian market, it is not similar. Americans really make quality products. Super concentrated product. Aside from using it, I'm passing it on to my friends and my students. Generally I get two or three flus a year. Once you started taking this product, the flu went away. I feel more disposed. I have more energy for day to day chores. I have more vital energy to correct my students' tests. I recommend this product to all people who work overtime like me. The tablets are very consistent. Easy to swallow. The pot is very useful in preserving the product. It has airtight lid that seals the internal product well, avoiding waste. It has otina evaluation on the website. I am very satisfied.
