Excellent customer service! Both times I needed to return a product

I don't know what I like the most. The product for sleeping is amazing as well as the magnesium. The customer service is spot on and I couldn't be happier. It takes a while to get your order but that is not their fault.

The product Magnesium Breakthrough did not overwhelm me but seemed to help my body feel better. Wither this was psychosomatic or real is still a question in my mind leaving me to wonder if other magnesium supplements were just as effective for half the price (after researching the different types of Mg). What concerns me is that Mg Breakthrough does not account for the amount of each type of Mg only to say that it is a "proprietary" blend which could mean anything. I found a different brand of Mg complex with most of all the different types as Mg Breakthrough has but was 1/4 the price. What made me switch was the ridiculous price of BiOptimizers products, and when I called to place a repeat order and attempted to negotiate a deal that was previously offered (6 for the price of 5), I was brushed off and they wouldn't budge. When I told them that they had just lost a repeat customer, they could care less. No call back - nothing except crickets. So I don't do business with them anymore. In addition, I am expected to recall the date of this failed negotiation with BiOptimizers? It was mid 2023, how's that?

I've used many BiOptimizers products over the years and have always been impressed with the quality and the results I see from the products. Recently I've been working with Eric from BiOptimizers sales staff and he's made me feel like a VIP. He's dealt with any questions I've had, chatted about options, and found the best deals for me. I can't recommend the company enough. Keep being awesome!

I love the product, but the website is a little difficult to navigate.
