Despite bold claims Okinawa Flat Belly Tonic is just a fruit extract drink, there's really nothing special about it and unless you're using it to replace full calories sodas then it isn't going to help you lose weight. There are a couple of ingredients in it that were they dosed effectively could claim to reduce bloating, however it is impossible that they are. For example, Turmeric contains about 20% curcumin.
For curcumin to be effective it needs to be dosed at 500mg and up to reduce bloating as Okinawa Flat Belly Tonic claims. However, the blend that contains turmeric is only a total of 465mg per serving and it contains 6 other ingredients. For standard turmeric to be effective you'd need at least 2500mg. So, even if we were trying to be generous here we're not off to a good start.
There's some probiotics in there, which could have a bloating reducing effect, but nothing that would make Okinawa Flat Belly Tonic more effective than taking a standard (much cheaper probiotic supplement). But, technically that does mean that at least it will live up to one of it's claims in that it should result in improved gut health, Although a 3rd rate probiotic that tastes like fruit juice probably isn't what most people are after when they're spending $70 on a month's supply.
All in all we don't recommend Okinawa Flat Belly Tonic. There are actually effective weight loss supplements and better probiotics available for the same price point.
Even trawling through Okinawa Flat Belly Tonic Reddit reviews it was relatively difficult to find any posts that weren't simply trying to sell the product rather than us actually managing to find any verified customer reviews of Okinawa Flat Belly Tonic.
This typically isn't a great sign, as it means that there's been great lengths to bury any legitimate ones. And seeing as the product isn't likely to live up to the promises made then we're not overly surprised.
There are a few testimonials and implausible okinawa flat belly tonic before and after photos, but again, these all seem to only be purposed towards selling the product.
Polyphenol Blend 2150mg
Cherry, Mulberry, Carrot, Green Mango, Hibiscus, Beetroot, Raspberry, Acai fruit, Black currant, Blueberry extract, Cranberry fruit, Grape Seed extract, Mango seed extract, Pomegranate.
This is the bulk of the product and the vast majority of the ingredients don't have any benefits in regards to weight loss. Hibiscus and Blackcurrant Extracts have some mild diuretic qualities and beetroot in quantities of over 500mg can have some benefits to blood pressure and heart health, but again not particularly great for a weight loss supplement.
The only other element of Okinawa Flat Belly Tonic that could have any benefit is the mango, if it's specifically mango seed extract (and some versions of the label list it as mango and others as extract, so this would depend on the version). However, studies are relatively limited and it would need to make up 350mg of the blend as a minimum so we're unconvinced.
Okinawa Flat Belly Tonic does also have Grape Skin Extract which if the doses are right could contain enough resveratrol to have some anti inflammatory properties, but it would need to make up about 70% of the polyphenol blend to be within the effective range, so we don't expect that's going to help Okinawa Flat Belly Tonic work.
Pretty much nothing else has much in the way of benefits that you're not just getting direct from the nutrients themselves.
Metabolic Blend 465mg
Okinawa Flat Belly Tonic reviews tend to focus on it's supposed weight loss qualities, but looking at the metabolic blend, it isn't going to do much to burn fat.
Cinnamon bark - This can be beneficial for weight loss however, you need 2g/1lb of body weight, so this isn't really going to do anything in what is likely to be a maximum of 100mg in Okinawa Flat Belly.
Green tea - This extract can have some mild weight loss effects, however, it's usually the worst ingredient in much better products.
Ginger - Ginger root as with Turmeric can have a host of benefits for bloating even potentially as a weight loss supplement (in that it it can boost testosterone production in males, helping them lose fat). However, the dose has to be between 1000mg and 3000mg and the blend only contains 465mg across all it's ingredients.
Turmeric - As mentioned in the intro, curcumin can have a benefit to reduce inflammation if it was here in a higher dose than is possible in okinawa flat belly tonic.
Shilajit extract - Shilajit does have a lot of benefits to brain health, but nothing for weight loss, added to which it typically needs to be taken in doses of 300mg or up, which is unlikely to be the case in Okinawa flat belly tonic's metabolic blend.
Bitter melon extract - This one may actually be OK, although generally speaking we've only seen it in lower quality weight loss supplements. And typically the studies that suggest it is beneficial for an increased rate of weight loss have it at 500mg/day doses, which once again is not possible within Okinawa flat belly tonic.
Black pepper extract - Black pepper or Bioperine helps people absorb nutrients more effectively, but doesn't do anything directly for weight reduction.
The digestive blend is all fine, we have no complaints here, it's nothing special, and would be in a lot of greens and reds powders (not marketed as a weight loss supplement).
Blue Agave Inulin 100mg - this is a prebiotic (meaning good gut bacteria eat it, but the body itself doesn't digest it), it's also a sweetener.
Probiotics 3billion cfu - Probiotics are good for gut health and typically reduce bloating. Some studies show they could potentially have a mild impact on weight loss, but most are correlative in that they showed people who lost more weight had better microbiomes, although there are a lot of explanations for said microbiomes being better, such as better diets.
