Customer service is very friendly and helpful. They helped me figure out which product would best suit my needs. I purchased the maple-vanilla flavor Liqui-Magnesium and it arrived within a few days. The flavor is far better than other brands I have tried and so far this product does what I intended it to do. It helps calm me down at night so I can relax before bed. An added plus, the cost is much more reasonable than other brands on the market.
