I placed an order with BiOptimizers on April 6, 2025, and requested a refund under their 365-day satisfaction guarantee. I contacted their support team on April 28 and again on May 1, both messages were ignored. Per their stated policy, I only opened one bottle of each product and returned everything else unused. This meets the conditions for a refund. Instead of honoring their guarantee, BiOptimizers has provided no response, no RMA, and no accountability. It’s now been over two weeks with complete silence. This isn’t about the refund, it’s about trust. If a company builds its brand around health, transparency, and customer care, ignoring valid refund requests violates all three. Until they respond and resolve this, I can’t recommend them to anyone. Order #: BHTSC37OI5 Contacted Support: April 28, May 1 (no reply)

I ordered the Digestive Health Stack in October 2024. I reached out today to use the 365-Day Guarantee on "all Bioptimizer products". The guarantee is included on the bottom of the Stack product page for digestive-health-stack. However, I was told that the guarantee doesn't apply to stacks or multipole bottles of the same thing. When I responded with the page information above, they sent me to a line in the terms and conditions that qualifies the 365-day guarantee. This significant and very expensive caveat isn't referenced even with an * on the guarantee on the Stack product page, so this is definitely underhanded and intentionally misleading. I'll never order from a company that uses such deceptive practices again.

I ordered their magnesium 12 days ago, the UPS delivery tracking changes every single day to the next day. I wrote to the customer service and the email came back after about 6 hours that it is not possible to deliver. Great product but awful service. I am leaving abroad and won’t get my package, although I ordered it 14 days before. Just for the info I ordered it to a very central Florida address where the delivery trucks come and go several times a day.

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.

I ordered 3 bottles of their magnesium... 7 days later, and UPS tracking label states that they still haven't received the item. I've called customer service, and they told me they would reach back out to me that day, they didn't... nor the next day. I even emailed their customer support email twice now in the last 3 days, and still haven't gotten a reply. Next step appears that i will have to contact my bank and get the charge disputed. NO TRUST or communication from this company and very disorganized. I needed these supplements in the window they were explained, and it's already passed due and it hasn't even shipped.

I ordered this for the first time. Took 1 tablet instead of the recommended 2, just to see how it would affect me. Within an hour I felt nauseous and light headed. Deciding that it wasn't going to be something I could take, I decided to look up their return policy. I was incredibly upset to find out that they wouldn't do a refund at all unless the bottle was unopened. So after spending over $40 on a bottle of supplements that I can't take I'm out this money. What's the point of sending something back that I haven't tried? You don't know how it's going to affect you or work for you unless you try it and then your just out this much money!

All the worst. I ordered the goods a month and a half ago and I still haven't received them. I write to customer service and no one answers. I lost 40e for nothing. Avoid this site.
