Appetite suppressant
I really love this product. I drank this in combination with a keto diet and lost 70 pounds. The lime is my favorite flavor. I have used the charged and not charged (caffeine or caffeine free). The only thing is that it’s 20 day supply and it’s on the expensive side if you live pay check to pay check. Otherwise a great addition to a diet.Keto//OS NAT Lime Time Keto Supplements – Charged – Supplement for Men and Women (20 Count

A Little Overpriced – But Tasty and Ships Quickly
I love the product, but ordering through Pruvit can take awhile. I was going on vacation and needed a supply before I left.Not sure it does anything for weight loss – but it’s an energy boost and tastes great without a weird aftertaste.

Bad Batch?
I normally love this product. The box I received this time – the powder was hard and chunky. I thought maybe it will still be fine, it wasn’t! The taste was terrible -I checked the date and it said it expired in 2025. I see other reviews from this time period with the same issue – please check the quality of your stock. Something is wrong with the batch! I am not able to request a refund or return but I will not be able to use this box of powder. A lot of money lost, very disappointed in the quality of this box.

Product is Great-Subscription is a bust
This product is great. I use the cacao flavor in my coffee to kickstart my day. Nothing bad to say about the product. It is a little high priced but worth it, in my view. Now the bad, For the first time ever, I put this product on a subscription so I would never run out and wouldn’t have to manually order. They have failed. I am now out, and have received no updates as to when I will receive my subscription order. It is now 9 days overdue, but you better believe they got their money first right. I went ahead and made another order but that product wont be here for over a week. So I am out of it and will now do without for 7-10 days because of it. It’s unfortunate but I have seen in many instances customer service everywhere has gone down the tubes. Really disappointed that the subscription service is a total failure.

Super Happy with results not the price
I ordered a box of this while eating keto and lost 10 pounds in a week. I love them but they are super expensive. I asked my family to order me more since my birthday is coming up. Wish I could keep ordering these. They taste amazing and am super happy that they curbed my appetite
