Don’t rely on email help
Accidentally ordered, cancelled and reordered. At no time in email follow up did anyone bother to say that if you immediately cancelled a subscription made in error the subscription would be cancelled but not the first package. Especially confusing since they kept just saying which order do you want to cancel? Which didn’t mean anything without an explanation. Terrible service.

Awful
Awful, scammy company. Asked for a refund for an unopened box and they kept stalling “waiting for an answer from the delivery company”. Had to initiate a chargeback to get my money back after several weeks and unreplied emails. Do not trust this company.

Probably one of the worst supply organisations I have used. After an order is placed they send out offers for a cheaper price!! They do not update existing subscriptions to the cheaper price. They fail to respond, continually debiting any payment data, failing to refund and putting right the errors.

Dear Peter, thanks for your feedback. On our part, we periodically launch offers to facilitate the purchase of our products, so it may happen that you receive the newsletter after placing an order. Then, we remind that subscription products, already available at a promotional price, are not subject to further discounts. Their price is fixed and it is not possible to set an automatic update. Anyway, we are committed to finding the best solution for any issue you may encounter, as your satisfaction is our main priority. Do not hesitate to reach out to our Team if you have any other needs.

L Nutra/Prolon Awful Customer Service - avoid
Prolon 5 order and subscription cancelled. Later that day Evri notified me they had received a package, from L Nutra, which they delivered to an unattended porch the following day without my having an opportunity to reject the package. NO return address on the box. I have emailed prolon.co.uk contact point at info@ in the prescribed time to exercise my right to return the product for a refund under the distance selling regulations but Prolon/LNutra have not acknowledged my emails to provide a mailing label - they remain uncontactable. Totally unsatisfactory customer service.

This works! Everyone should try it.
As I write I am in the middle of day 5 and have not felt this good since the last time I did it in July. I have stocked up thanks to Black Friday sales and will be doing it monthly for another 4 months to keep this feeling going. Everything improves immeasurably from day 4; sleep, mood, sugar levels, food cravings - it all just gets better.
With a bit of preparation the week before, i.e. reduce sugar, meat and alcohol consumption, you will not be hungry. Don't let the word 'starvation' put you off - it is not a starvation diet. And before you know it, 5 days have past and you look and feel amazing. I have recommended this to everyone I know and do, wholeheartedly, to everyone who reads this.
P.S. Another bonus is how it reveals your real relationship with food. I thought I never snacked and ate healthy foods, then the truth came out when I craved sugary tea, biscuits and fried chicken, and I realised how I would reach for food (sugar) for emotional comfort - it's eye opening.
Good luck! You'll thank yourself for doing it.

The best fasting
I have done 4 rounds of 5-day fasting and can’t be more happy with results in terms of weight loss and health. Prolon obviously knows what they’re doing, fast is balanced, food is good (I really liked version 4) also they provide zoom support with Prolon nutritionists which is very helpful. Highly recommend

Perfect addition to my fasting routine
I recently tried the ProLon Shake, and it’s been a fantastic addition to my intermittent fasting routine! The product arrived right on time, and I was pleasantly surprised by the taste – smooth and satisfying without being overly sweet. It keeps me feeling full and helps me stay on track with my fasting goals. Highly recommend for anyone looking for a tasty, reliable option to support their fasting diet!

Food very repetitive
Food very repetitive, soups horrible. Not worth the money - better to make your own fresh versions of it.

Reply from ProLon UK
Dear Andy, thanks for your feedback. We are sorry you didn't have a positive experience with the ProLon products! We are aware that the packaged product is not always appreciated, but you should consider that the protocol must be standardized, so as to recreate the same conditions for each use, reducing to a minimum the variability that would occur with fresh food. On our part, we have developed four varieties, so you can choose the one closest to your tastes. The fourth, in particular, contains a greater variety of soups and breakfast bars than the previous ones, as well as other important innovations. Soon, we will also launch a 5-Day kit with a new line of soups, fresher and ready-to-eat. For any further questions, do not hesitate to contact us at info@prolon.co.uk!

Great Plan to use for better health.
Ordered the 5 day plan. It arrived promptly. Good instructions on how to prepare and eat everything. I found the plan quite easy, I didn’t get hungry at all. I am a seasoned faster though, fasting every day and a 40+fast Sunday to Tuesday.

ProLon is an incomparable reset and longevity tool. I have used it for ~8 years and find it helps keep me balanced and healthy by using it a few times a year. I am impressed by the science and clinical results. When I first started ProLon it was challenging. Now it is straightforward. It still takes patience and lifestyle adjustment, but all to the good.
