I've been trying to buy Prolon for over two weeks, but the website keeps kicking me out. I also tried getting help via chat and sent messages, but no one responded. I hope the product is worth the time I've waited to get it.

Hidden Checkout Charge and Customer Service Ignored My Refund Request
During checkout on a $360 order, a $10.68 “Order Protection” charge was quietly added without me intentionally selecting it. That feels like it was snuck into the cart, which is not something I appreciate from a company I’m trusting with my health products.
After noticing it, I contacted customer service and clearly requested that the charge be removed and refunded. Instead of addressing the request, I received a templated response explaining the benefits of the protection plan, completely ignoring the fact that I asked for the charge to be removed.
So to summarize the experience:
• An add-on charge was inserted into my order that I did not knowingly select
• I requested a refund
• Customer service replied with marketing copy and ignored the request
That is why this review is one star.
The charge itself is small. The issue is the practice and the response. Sneaking optional fees into checkout and then ignoring a direct refund request is frustrating and unnecessary. Just process the refund when a customer asks.
Hopefully someone there actually reads this feedback and fixes the checkout experience.

We truly appreciate you taking the time to share your experience and want to sincerely apologize for any inconvenience or frustration you encountered during checkout. We completely understand how upsetting it can feel when unexpected charges appear or communication feels unclear. Please know that we hear you, and your feedback is extremely valuable in helping us improve.
To provide clarity on the Onward Order Protection charge: this is an optional add-on designed to safeguard your purchase and give you extra peace of mind. When selected at checkout, it provides benefits such as:

Carbon Neutral Shipping – offsets CO₂ emissions from your shipment
Priority Support – skip the line and receive expedited assistance from our customer care team
This is our way of helping you shop with confidence, ensuring your order arrives safely, and giving you access to valuable perks. While the charge is added as a default, we understand that preferences vary, and multiple options exist at checkout to adjust or remove it if desired.
However, our Customer Service Team has already reached out to you directly via customerservice@l-nutra.com to help clarify your concerns and work with you toward the best possible experience. We are dedicated to making your experience as smooth, reassuring, and positive as possible.
Your satisfaction and trust are our top priorities. Please let us know how we can best support you moving forward. We’re here to help every step of the way.
Love Prolon products
Love Prolon products. Want to get your organic but cannot afford it anymore. The difference in price between the regular and the organic in my opinion is outrageous. I know it’s organic, but still that much difference?

Hi Sierra,
Thank you for sharing your feedback. We completely understand your concern regarding the pricing, especially when comparing the traditional program with the organic Next Generation option.
Our goal is always to make our programs as accessible as possible while maintaining the quality and scientific standards behind them. The price difference largely reflects the use of certified organic ingredients, updated formulations, and the additional sourcing and certification requirements associated with organic production. That said, we understand that the program can represent a meaningful investment in your health.
We are continually working to improve our offerings and find ways to make them more cost-effective so that more people can benefit from the program, which is built on more than 20 years of scientific research.
As we want to ensure we can support you in reviewing the available options or finding the best choice for your goals and budget, please feel free to reach out to us at customerservice@l-nutra.com. We would be happy to assist you further.
We truly appreciate your continued support and are grateful to have you as part of the Prolon community.

Prolon is an excellent addition to healthy eating
The Prolon program is supported by excellent science. The staff is knowledgeable and friendly. The website is very good. I’ve been wanting to do a 5 day water only fast for a while now, but was concerned about loss of muscle mass. Prolon seems safer in that respect. I’ve completed 3 Prolon 5 day fasts so far with no noticeable reduction in muscle mass, or strength.

Hi Victor,
Thank you so much for your thoughtful review. We truly appreciate you recognizing the science behind the Prolon program, as well as the efforts of our team and website experience. Your kind words mean a great deal to us.
We also sincerely appreciate your constructive feedback regarding the default setting for the 5-Day kit. That’s a very helpful insight. We do offer both a one-time purchase option and a subscription option, so customers can choose what best fits their goals. The subscription is designed to support those planning multiple cycles, but we completely understand how having the single-purchase option more clearly highlighted may feel more straightforward. We truly appreciate you sharing this perspective.
We will absolutely share your feedback with our team for consideration as we continuously work to improve the ordering experience.
Thank you again for being part of the ProLon community and for taking the time to share both your praise and your suggestions.

The Science makes Prolon 5 day fast makes this the best option for me
The science behind the Prolon 5 day fast makes it one of the best healthy total body and metabolism reset out there. The combination of nutritionally balanced meals and snacks makes it easy to stay on point until the end. Losing a little weight and not sacrificing muscle or skin integrity is the best of all options. Everyone can benefit from this program regardless of their diet and health.

I understand how frustrating it must have been to receive multiple emails prompting you to complete an order when you had already received a confirmation number. That would absolutely feel like a miscommunication, and I apologize for the added stress.
In some cases, automated reminder emails can still be triggered if a cart remains active in the system, even after checkout is completed through a separate session. That said, we recognize how confusing that can be and appreciate you bringing it to our attention.
