This review is for Bioprimizers UK. Unfortunately I have had an issue with an order which has not been delivered due to a wrong postcode. I don’t know if the mistake was me or them. This isn’t the problem, tbe problem is you can’t talk to anyone, they don’t respond to emails & you just can’t sort anything out. I have called Royal Mail myself & they told me it had a postcode in Wales on the package, I live in Essex. UPDATE, I have now had a response from the customer service department who said they had an issue with their email system. They have given me a partial refund & sent a new item out to the correct address so I am more than happy with this.

This company is breaking the law
This company is breaking the law. In the United States, the FDA requires manufacturers to list the specific quantity and name of each dietary ingredient in a "Supplement Facts" panel. Ingredients must include measurements like milligrams (mg) or micrograms (mcg) to show the amount per serving. They don't provide this information, which is highly suspicious. Some forms of magnesium are cheaper than others, and are less easily absorbed. There's a lot of hype on this site, but little real information.

Hello Janet,
Thank you for contacting BIOptimizers! My name is Kerry-Ann, and I am your Happy Health Concierge assigned to assist you today.
Our apologies for any confusion you may have regarding our supplement facts breakdown.
Our Magnesium Breakthrough uses a proprietary formula, which is fully compliant with FDA regulations. As required, we list the total amount of the proprietary blend per serving (500mg), along with the different forms of magnesium included, in order from highest to lowest quantity.
This labeling format is standard and ensures that you know exactly what types of magnesium are present, while protecting the unique formulation that makes our product effective. Please rest assured that our products meet all regulatory requirements for safety and transparency.
If you have any further concerns, please feel free to call us at 1-800-719-2467 or email [email protected].
Wishing you happiness and great health, take care!

365 Day Money back guarantee
I purchased bioptimizers magnesium breakthrough back in I think it was Sept 2025. I purchased it for myself and my wife hoping it would really help her with sleeping and more energy. Well it really did not help either one of us, so after two months and nothing I decided to get my money back so I called and explained what I wanted, don’t believe there money back guarantee of 365 days, you will only get your money back on any unopened bottles so if you order six bottles and you have taken it for five months and now your on your sixth or last bottle and it hasn’t helped you at all so you call and explain it hasn’t helped you are asked how many unopened bottles you have left well guess what you don’t have any unopened bottles so you do not get a refund. They don’t give your money back because their product did not work for you they only give your money back on any unopened bottles you return to them. This is very bad customer relations and service, so to me there product is a fraud. a fake. Don’t buy it !!! It doesn’t work

Tried to place an order
Tried to place an order, cart is horrible
Then did a live chat and agent was quick, I was trying to place a large order for my clients. They told me the website and cart is getting fixed and they sent me to Amazon to pay Full price and even to go to sprouts and even pay more than full price. I'm a Chek practitioner and now looking for another vendor

Bioptimisers uk
Bioptimisers uk. Sent out a subscription even though I had cancelled and have simply not responded to any email or contact to simply return unopened order. Sad thing is I buy quite a bit from them, but this episode has resulted in my electing to switch to a different supplier for my supplements. I simply wanted to return and re-order when I need new supplies. Post sale support is the measure of a great company and sadly they (vipertech as their agent in the uk managing orders) have spectacularly failed. So disappointing

Product did not work
Update:
They were very very quick and good about handling the refund. I updated the stars to reflect this.
They are very misleading and rely on the heaviest marketing to sell their products. I purchased Masszymes and the products do NOT help at all. I have used digestive enzymes in the past from reputable companies like Thorne and can literally feel the difference in my digestion. I don't know why I thought I could find something better, especially through such a scammy looking website... It's my fault in the end.
