Okinawa Flat Belly Tonic Review: Legit for Weight Loss?

Okinawa Flat Belly Tonic Review: Legit for Weight Loss?

| |
| |

Okinawa Flat Belly Tonic is a weight loss supplement manufactured by a brand called Vitalina. This company manufactures a probiotic weight loss supplement called BioFit which we previously reviewed very negatively.

In this article we’ll review the ingredients in Okinawa Flat Belly Tonic to provide our determination on whether or not this supplement is likely to be effective for weight loss. We'll also share some concerns we have about the manufacturer.

At the time of updating this article, Vitalina appears to have discontinued Okinawa Flat Belly Tonic as the product is not currently showing on their website. We'll leave the ingredient review up incase the brand re-launches this product, and we'll also highlight some research-backed weight loss supplements for the convenience of our readers.

Ingredient Review

Okinawa Flat Belly Tonic ingredients

All three active ingredients in Okinawa Flat Belly Tonic are ketone salts: magnesium beta-hydroxybutyrate, calcium beta-hydroxybutyrate and sodium beta-hydroxybutyrate.

We cannot identify any medical research with human trial participants proving that any of these ingredients are effective for weight loss, nor did Vitalina cite any prior to discontinuing this product, so we will consider this formulation to be ineffective for weight loss.

We don't recommend taking exogenous ketone salts without the approval of a doctor, because we haven't come across much medical research on the safety of these compounds, nor can we identify any clinical trials suggesting ketone salts are effective for improving any aspect of health, irrespective of weight loss.

The brand also misspelled an inactive ingredient called silicon dioxide as "silicone dioxide."

At the time of initially writing this article, Vitalina's Okinawa Flat Belly tonic product listing on Amazon did not include a Supplement Facts label.

This clearly violates Amazon’s dietary supplement guidelines, which state that dietary supplement images must show all sides of the product label including the ingredients list.

Supplement Facts labels list the dosage of each ingredient which is important information for consumer health and safety, and we recommend avoiding any supplement brand that fails to publish a Supplement Facts label on their website or Amazon listing. 

Overall we cannot identify any effective ingredients in this formulation and we recommend avoiding it.

Our Clean Weight Loss Picks

There are food-based nutrients which have been shown in medical studies to be effective for weight loss.

Dietary fiber was shown in a medical review published in The Journal of Nutrition to cause 16 pounds of weight loss in 6 months when combined with moderate caloric restriction (750 calories per day below baseline).

Supergut Fiber Mix is our top fiber supplement, because it contains three different types of fiber powder, and retails for only $1.75 per serving at a subscription rate.

MCT oil was shown in a meta-study to cause more than one pound of weight loss over 10 weeks. This equates to potential annualized weight loss of 6 pounds per year with less than one tablespoon's worth of MCT oil per day.

Bulletproof MCT Oil is our top MCT oil product, because the only ingredient is MCT oil derived from coconuts. and it currently costs only $15.50 for over a month's worth of product.

Ginger intake "significantly decreased body weight" according to a 2019 meta-study on ginger and weight loss that analyzed data from 14 clinical trials.

Pique La Ginger is our top ginger product, because it's an organic tea in convenient crystallized form, and all that's needed is to pour the powder into a glass and add hot water.

All three of the products mentioned in this section are entirely free of additive ingredients that we consider to be unhealthy or unsafe.

Okinawa Flat Belly Tonic Side Effects

Exogenous ketones do cause side effects in some patients. A clinical trial of supplemental ketone salts with healthy adult participants caused 1 of the 6 participants to drop out due to severe vomiting, nausea and abdominal pain. This was a small trial, but similar reports have been documented in other studies.

The risk of side effects may be higher in Okinawa Flat Belly Tonic than other ketone salt formulations because the ingredient doses in this supplement are not published.

Stay up-to-date on our research reviews


We recommend avoiding both Okinawa Flat Belly Tonic and all supplements sold by its manufacturer Vitalina. We are unable to identify any medical research with human trial participants suggesting that any ingredients in this formulation are effective for weight loss.

Vitalina, the brand that manufactures this supplement, failed to publish ingredient doses on their website or Amazon listing for this product, which we believe is a consumer safety issue.

It appears that this product has been discontinued by the official manufacturer Vitalina, and we do not recommend buying any other supplements called "Okinawa Flat Belly Tonic" currently being sold on Amazon.

Dietary fiber and MCT oil are research-backed weight loss supplements without any significant side effects.
