Best ever!! Thank you so much!!!!!

I took the chance. Which I don't like doing. Because of the price. ( Low income) and seeing the Reviews and so I bought one bottle. Then like when they were almost gone, I stopped taking them, and OMG the night sweats, lack of sleep. And everything just came back!!! I was feeling terrible. But started again. Symptoms went away!! And bought more. Waiting for some to be delivered. I will not run out again! This works, I promise you. Take that chance. 🙏🙏🙏🙏🙏🙏

Recovered quicker

My wife had a flu bug recently. I had been taking these for a few months but my wife had not. Once she had started taking Dr. Berg's Advanced Immune Support, she was able to knock out her flu faster. Her fever came down and was able to recover much faster than if she hadn't taken them.

It works as advertised. There's also a video on Dr Berg website that goes over the product.

I like the product because it does what Dr Berg says it does. I've been taking it for abt a year and have not gotten sick. No flu, no covair, etc!!!!!!!!!!!!!!!!!!!!!!JB

Why did you not add Copper to the formula?

Copper is needed to help make Zinc work in the body.
