On the face of it, I like it - its not easy to find a bio/ organic Magnesium compound. However, on 3 separate occasions I found damaged capsules/ half empty/empty capsule shells in 3 separate batches.. The UK distributer was very responsive at addressing the problem, BUT I'm extremely unconvinced with the manufacturing process. I strongly suspect Biooptimizers are focused on an aggressive marketing campaign (also involving influencers) to try copy the success of AG1 and others, and hence are happy to sacrifice on quality control. Given I've consistently received poor quality product also leads me to think that the actual magnesium compounds inside Bioptimisers may not be as high quality as they make us believe. I've therefore found other magnesiums. I'd encourage buyers to tread carefully with this company (and likely others!)

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

I used to think this was a great company however I’m beginning to have my doubts. They’ve become such a hit that it now takes 2 week to get an order which is ridiculous for the amount of money the charge. I’ve been greatly disappointed with this last order and how it was handled. They convince you by making you think the the only company out there that has such superb products. I am going to look into other companies. You can also get these on Amazon now. And you get them much quicker but the fee is slightly higher in top of an already high price. I’ve been using these products for a long time and I’m not sure if I will continue.

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?
