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
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.Â
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 recommended fiber supplement, because it contains three different types of fiber powder and no questionable additive ingredients. Interested consumers can check out Supergut Fiber Mix at this link to the product page on the brand's official website, where it retails for under $2 per serving at a subscription rate.
MCT oil is quickly absorbed by the body and increases metabolic rate, which causes fat loss. A 2015 meta-study on MCT oil documented 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. There are no questionable additives. Interested consumers can check out Bulletproof MCT Oil at this link to the product page on the brand's official website, where it currently costs only $15.50 for over a month's worth of product.
Coffee is one of the few whole food ingredients associated with weight loss in clinical trials. A meta-analysis published in the Nutrients journal found that coffee intake was associated with reduced body mass index (BMI) and waist circumference.
VitaCup Organic Instant Coffee Sticks is our top coffee product for weight loss, due to its convenience. No preparation or machinery is needed. The sticks can be mixed into hot or cold water (or other beverages) and consumed. The only ingredient is organic instant coffee; no questionable additives.
Interested consumers can check out VitaCup Organic Instant Coffee Sticks at this link to the product page on the brand's official website, where they retail for $1 per serving at a subscription rate.
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.
