Great product and service!
By Shabir
I absolutely love BiOptimizers products. First I bought magnesium breakthrough which helped me so much with anxiety and the 2nd product was mushroom collagen . Then 2 together changed my life. Customer service is brilliant especially Jessica which is always helpful. 100% recommend

I was actually having severe pains from by butt to my leg those pains were unbearable, painful and severe i started the magnesium breakthrough on October 24th I started feeling better with no pains on November 3rd today is November 18th I’ve been pain free. Please consider taking it for muscle and nerve

I have tried a lot of different magnesium formulations, and I like this one. Maybe it's the individual ingredients or maybe it's the synergy, but I did feel that my breathing while running was improved while taking this. Looking forward to taking this another couple months and then rechecking my lab work to see how it makes a difference!

I have been taking magnesium, enzymes and probiotics for the past 3 years. My health and performance have never been better! I highly recommend it.

Excellent customer service! Both times I needed to return a product
By Shopper M.
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.

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!
