I've grown up with Mannatech in my life ever since I was young. I've been blessed to experience a healthy lifestyle I believe mainly because of Mannatech. I especially love Osolean; adding it to my daily coffee.
I don’t usually write reviews, but this was too remarkable not to share. My husband was dealing with a painful case of shingles, and we were just hoping for some relief. We tried a product from Mannatech, and within 24 hours his pain completely subsided, and within 48 hours, the improvement was undeniable. His skin visibly was clearing up dramatically. It wasn’t subtle. It felt Instant in just taking 2 twice a day. Everyone’s experience may differ, but for us, this was incredible and absolutely worth looking into. Keeping this stocked!
I have been trying to cancel my monthly order since August last year. Thry continue to take almost R2000 from my account every month. It has finally come to a stop. I have the monthly stock sitting in boxes ready to be returned, but in signing the form I waiver my rights, this includes postage! Its R75 every time! And now I must pay for returns as well. That is total insult to injury given if I could afford it I wouldn't be stopping my supply. I am disgusted at the service and total disregard and lack of care for a long standing supporter of this product. This has caused me so much anxiety. I am at my wits end as not sure how to fix this extremely simple situation. U basically stole my money ' im demanding u return it. End of story. U should be ashamed!
I like the company, because there's faithfulness if you find a true partner.
Mannatech has now stolen money from my credit card for the third time. Sending me products I did not order. They take no responsibility for this, rather forcing me up jump through excessive hoops, holding my money for months and forcing me to cover interest on the credit card payments. Their customer service representatives provide no assistance whatsoever. It is disgraceful that an alleged wellbeing company can operate while treating humans with such disrespect and disregard. I am hoping to cancel my account but who knows, probably get sent something I didn’t order in another few months.

My MiL has been on Mannatech for years and has encouraged me to use their products. I know she deeply believes in them, but going onto their so called Cdn site I was dumbstruck by all the “keywords” utilised, without ANY medical information included- cell to cell communication?? Which cells and how is this possible pathophysiologically? Sorry I am looking for specific things such as GI support as I have a medical condition that needs some targeted support? Also menopause is real and I would like to try to use a supplement that could help with this specifically. They are trying to sell u their business in order to buy it for 49.99 Cdn-!but no knowledge spoken ethically? Or using correct medical terminology- I am also
Thank you for sharing your concerns. We truly value honest feedback and the opportunity to clarify some important points. Mannatech products are nutritional supplements, not pharmaceutical drugs. That means they are not designed to diagnose, treat, cure, or prevent medical conditions. Because of this, you won’t find medical terminology or claims tied to specific diseases on our website. However, Mannatech does invest in published, peer-reviewed research on many of our flagship products. You can review this science for yourself at www.mannatechscience.org. Since supplements are not medications, we cannot and do not make claims regarding medical treatments or targeted disease support (such as for GI issues or menopause). We always recommend consulting with a qualified healthcare professional for guidance specific to your condition. Our focus is on providing high-quality supplements that support overall wellness. While everyone’s body responds differently, many customers—like your mother-in-law—have found value in incorporating Mannatech into their wellness routines. Becoming an Associate is completely optional. Anyone can purchase products directly without enrolling in the business opportunity. We strive to make this clear so customers can choose what works best for them. We hope this helps bring clarity, and we invite you to explore our published research or contact our Customer Care team if you’d like more detailed guidance on our products and how they may support your general wellness. — Mannatech Family
Good products and service, but they constantly send me spam mail.
Thank you for your honest feedback. We’re glad you enjoy our products and service, and we also hear your concern about receiving too many emails. You’re right—we’ve been sending more than we should, and we’re actively working on an initiative to reduce and streamline our communications. Our goal is to keep our customers and Associates informed without overwhelming your inbox. We truly appreciate you bringing this to our attention and for giving us the opportunity to improve. —Your Mannatech Team

Luminovation skincare with its benefits is not my favorite. Wash and toner all agents stories from no make up remover IS NOT TRUE ,u still need to use makeup remover after 3 weeks using facewash just landed in a humid country ,face wash reacts super oily in a short period of an hour. After a launch there was before and afters where the young woman look the same and not for African ladies as she looked horrible after. U decide for the price u expect a miricle ,product not suitable for everyone. I'll stay with Estee lauder thank you.

I have been ordering products from Mannatech for over 15 years. I have always been more than satisfied with their professionalism and the products are absolutely top class. Our whole family is taking Mannatech products every day, and will continue forever. Thank you Mannatech
Was very ill with the product so they accepted a return and said they would refund me. Been 2 months now with many promises, but still do not have refund. Despite the response below, I have done that already 4 times, just useless, more and more failed promises. Also note this is a UK review, but no UK telephone number, so I am expected to also chase US, Spain etc. Just stay away from this company and save your money.

Mannatech This is the most amazing product that I have ever used. I will never use anything else again. The company is also trustworthy and delivery quick and effective
I've been using the Mannatech products for 18 years, specifically the Ambrotose technology and the other core products Plus, AO and Catalyst. My family and I have experienced wonderful wellness results as a result of these technologies. I would highly recommend these products to anyone who wishes to maintain their wellness.

Day 35 of trying to get my money back from Mannatech! My wife is an associate and Mannatech has, belatedly, agreed to refund the final £56.25 of three orders that were never delivered... this totalled over £230 held by Mannatech in accounts for over a year. Mannatech has benefitted from holding my money and been in clear breach of contract under the UK Consumer Rights Act 2015 (payments made for goods never received). As of today, the final £56.25 has not been refunded... despite Mannatech claiming they paid it back last week! Then they wanted to check a bank account that they had refunded £177 to just two weeks ago... either delaying tactics or just complete incompetence. In all three instances Mannatech simply took money and never provided any goods. All of these instances were Mannatech's errors, not ours. Yet when the company's customer services department contacts you they make out they're doing you the biggest favour ever when, in fact, they have effectively stolen money and kept it in their accounts. A message to any Mannatech associate... a simple check of my wife's activity being an associate (for just over 2 years) highlighted over £230 of funds taken out of our bank account with no goods ever received. I urge all Mannatech associates to check the full history of your dealings with this company as it might highlight similar discrepancies in your accounts. Indeed, I know of another associate who is owed a hell of a lot more (around £2K). Check all your orders and bank statements to make sure you haven't been charged for goods you never had...
I ordered some products. They made me violently ill, so contacted the company, they sent me a label to return. I did that expecting a refund. A week later I get them back, with another almost $550 charge to my CC. I complained again so they told me to return them again. That time I had to pay for shipping which was almost $34. I did get the the almost $1100 back as credit, but they changed me for returning both shipments which ended up being about $46. Very poor business on their part and the products were unimpressive with getting so sick.
