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.

Manufacturer Concerns

We have concerns about the manufacturer of this supplement named Vitalina. As stated in the intro section, we consider BioFit (the other Vitalina weight loss supplement that we reviewed) to be ineffective. That product also did not have a Supplement Facts label on its product page or Amazon listing.

Vitalina discontinued BioFit as well.

We recommend avoiding any supplements manufactured by Vitalina. We consider them to be a low-quality brand, and the lack of published ingredient dosage information is concerning to us.

Our Weight Loss Supplement Recommendations

There are several weight loss products that we recommend due to their research backing and lack of side effects.

Dietary fiber is a safe and effective weight loss supplement.

An extensive medical review published in The Journal of Nutrition found that dietary fiber intake directly predicts weight loss when consumed at a high enough dose. Fiber is zero-calorie plant matter that makes you feel full faster, and consume fewer calories overall.

The fiber supplement we recommend is SuperGut Fiber Mix. It contains a clean and effective formulation: a blend of three different types of unflavored dietary fiber and zero additive ingredients. It can be mixed into liquids or foods. Interested consumers can buy SuperGut fiber at this link.

We recommend using two fiber mixes per day, which provides 16 grams (g) of fiber. This is within the effective fiber dosing range associated with the greatest weight loss outcomes in the above-linked study.

Medium-chain triglyceride (MCT) oil is another dietary supplement which has been shown in clinical trials to cause weight loss.

MCT oil is quickly absorbed by the body and increases metabolic rate, which causes fat loss. A meta-study on MCT oil documented weight loss of 1.12 pounds over 10 weeks. This equates to a potential annualized weight loss of 5.84 pounds with MCT oil supplementation.

We recommend Bulletproof MCT Oil as our top MCT oil product, because it has a clean and effective formulation. The only ingredient is MCT oil derived from coconuts, and the product has no questionable additives. Interested consumers can buy Bulletproof MCT Oil at this link.

The effective dose range of MCT oil for weight loss (based on the medical review) is 1.7 g to 10 g per day. Bulletproof's MCT oil provides 14 g in one tablespoon, so around two-thirds of one tablespoon should be a maximally-effective dosage.

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.

Other Okinawa Flat Belly Tonic Brands

Even though Vitalina has apparently discontinued Okinawa Flat Belly Tonic, there are a number of other manufacturers on Amazon selling products by the same name. We do not recommend purchasing Okinawa Flat Belly Tonic from any of these companies.

In our opinion, dietary supplements made by companies other than the official manufacturer tend to be poorly formulated. It's a sign of a low-quality supplement brand to create a product with the same name as a competitor to try to take their market share.

Questionable YouTube Reviews

There are a number of YouTube reviews of this product and we cannot identify any that we would consider unsponsored. In nearly all videos that we reviewed, a person with no medical credentials is speaking vaguely about the health and weight loss benefits of Okinawa Flat Belly Tonic with no citations for their claims.

Many of these YouTube videos have links in the description to various Okinawa Flat Belly Tonic distributors.

We recommend being very cautious about believing health claims from these videos, as we were unable to locate one single YouTube review of this product which appears unsponsored, unbiased and well-researched.

Conclusion

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.
