Sumatra Slim Belly Tonic

Sumatra Slim Belly Tonic is like a sleep aid supplement masquerading as a weight loss formula.

Don’t get me wrong: sleep is crucial for weight loss.

Your body produces crucial weight loss hormones while you sleep, for example. It also repairs and recovers, helping you keep up with your exercise program.

But the makers of Sumatra Slim Belly Tonic appear to suggest you can simply sleep your way to significant weight loss. Users featured on the official website claim to have lost 42lbs within 6 weeks, for example, by taking Sumatra Slim Belly Tonic.

Features

One of the key areas of “science” behind Sumatra Slim Belly Tonic involves blue light exposure.

The makers of Sumatra Slim Belly Tonic claim blue light exposure, late at night, could interrupt fat burning overnight, preventing you from losing weight – even if you’re eating right, exercising, and doing everything right.

By taking Sumatra Slim Belly Tonic nightly, you can purportedly promote a balanced sleep, helping you burn fat overnight.

That may sound good. However, you can’t simply sleep your way to weight loss, no matter how many sleep aid supplements you take.

Ingredients

The ingredients in Sumatra Slim Belly Tonic are similar to the ingredients found in your average sleep aid supplement. You get valerian and 5-HTP, for example – two cornerstones of sleep supplements.

What makes Sumatra Slim Belly Tonic unique, however, is the other ingredients – like blue spirulina, black cohosh, and berberine. These ingredients aren’t directly linked to sleep but could promote weight loss in other ways.

Valerian Root: Valerian root is best-known for its sedative properties. Some take it daily to promote sleep. Others take it for anxiety or overall restlessness. There’s no good evidence linking valerian root to weight loss. However, being anxious and stressed is not good for weight management.

Humulus Lupulus: Better-known as hops – yes, the same ingredient in beer – Humulus lupulus has surprising links to weight loss. Some studies suggest hops can inhibit weight gain and reduce adipose tissue mass in animals following a high-fat diet. A 2013 trial, for example, found hops inhibited long-term obesity in mice fed a high-fat diet. However, there are few human studies showing this same connection.

Griffonia Simplicifolia: Griffonia simplicifolia seeds are one of nature’s best sources of 5-HTP. 5-hydroxytryptophan (5-HTP) is a precursor to serotonin, which helps you relax. Some people take 5-HTP supplements nightly to promote satiety, reduce food intake, and help with weight loss.

Berberine: Berberine is best-known for its effects on blood sugar. Some take berberine daily to support healthy blood sugar balance. However, berberine has also been linked to weight loss, BMI, and reductions in waist circumference, among other benefits. In one meta-analysis, researchers found berberine supplementation was linked to a significant improvement in BMI and waist circumference across 10 trials involving hundreds of participants.

Blue Spirulina: NASA gives spirulina to its astronauts to boost nutritional intake in space. Today, you can get that same spirulina in Sumatra Slim Belly Tonic. Spirulina has been linked to reductions in body weight, body fat percentage, and waist circumference in obese and overweight individuals, based on the results of one meta-analysis.

Black Cohosh: Black cohosh has been shown to decrease body weight gain, reduce fat mass, and even help with insulin resistance in animal trials. However, largescale trials on humans are limited. Nevertheless, many take black cohosh daily for detoxification or weight loss.

Inulin: Inulin is a prebiotic fiber linked to gut health, weight management, and blood sugar balance. In one trial, inulin was shown to promote weight loss and reduce body fat in a group of adults with prediabetes. Participants lost significant weight and overall fat mass with inulin compared to a placebo.

Lutein: Lutein is a carotenoid, or a type of natural antioxidant, typically found in eye health supplements. For whatever reason, lutein appears to exhibit antioxidant effects specifically around the eyes. There’s no major evidence connecting lutein to weight loss, but the antioxidant effects could promote healthy inflammation levels to indirectly help with weight loss.

Trick Factor

If Sumatra Slim Belly Tonic was simply advertised as a sleep aid with mild fat burning properties, we would have been okay with that.

However, the official website dips into bizarre territory: it tentatively links the ingredients to the Indonesian island of Sumatra, for example.

Where Sumatra Slim Belly Tonic really loses us, however, is in the weight loss claims. One verified user, on the official website, claims to have lost 42lbs in 6 weeks with the supplement. We guarantee that didn’t happen.

The only way to lose weight is by maintaining a caloric deficit. Getting a better sleep can help, but it won’t cause you to lose 1lb per day.

Pricing

Sumatra Slim Belly Tonic has fair pricing compared to other sleazy weight loss supplements available today – some of which are now priced at $69 to $79 per bottle.

However, you’re still paying a high premium for a sleep aid supplement. You can find 5-HTP and valerian supplements, for example, for a quarter of the price.

Sumatra Slim Belly Tonic does, however, contain ingredients not typically found in sleep aids – including pricey ingredients like blue spirulina. We didn’t dock the score too much for pricing.

Sumatra Slim Belly Tonic: Overall Rating

Overall, Sumatra Slim Belly Tonic spins a tale about how blue light exposure, late at night, is causing you to be fat. Even if that’s the case, Sumatra Slim Belly Tonic won’t help you automatically overcome that – even if it does contain a blend of ingredients linked to sleep and fat burning.
