There's a lot of marketing hype around Protetox, but very little substance behind this weight loss aid. Half of the ingredients in Protetox have been debunked and the other half can't possibly be dosed high enough within a single capsule and are normally only included in supplements that require 4 pills a day to be effective. Protetox also misses out on a lot of more effective fat burning ingredients in favor of ones that simply sound more exotic.
We suspect that in the effort of trying to differentiate themselves from other diet pills they've done themselves a disservice. A few of the ingredients like Banaba have had some very early research suggest that they may have some benefit, but there have yet to be any notable trials, and we're looking at speculative cell data, not tested in real life and quite often ingredients that work well in these studies don't translate to real world clinical trials.
The fact is that a caffeine pill with some added cayenne pepper would likely be more effective than Protetox and it simply doesn't hold a candle to any of the best fat burners on the market right now.
We don't recommend Protetox, and generally we don't recommend fat burners that don't contain any of the many well backed ingredients that have been clinically trialled and proven over the last few decades. Protetox falls into this camp.
None really hype up their antioxidant qualities like Protetox, because that's not really something that largely effects weight loss. There's a bit of pseudoscience around it, which largely comes from the back of antioxidants reducing joint pain making it easier for obese people to exercise, but it's not directly related to losing fat, which ultimately can only be achieved by using more calories than you consume and Protetox doesn't really help with that.
Generally speaking we recommend Instant Knockout if you're looking for a good all round fat burner over Protetox. The most effective weight loss supplements generally focus on appetite suppression, keeping energy levels high whilst dieting and thermogenic effects (metabolism raising), not antioxidants.
It's hard finding verified customers Protetox reviews, however, the ones we did find were generally middling. Most of the reviews we were able to find were on social media or reddit, although the general gist of these wasn't particularly positive. We didn't find many complaints of protetox side effects, which isn't surprising seeing everything is relatively low in terms of dosage. The most common complaint in negative Protetox reviews was that didn't actually work. Which we can't say came as much of a surprise.
As for Protetox Amazon reviews, these aren't actually something we can look at as valid, seeing as this seems to be a fake product. So we can't advise that you purchase protetox from amazon. This is quite common with supplements that have large advertising campaigns unfortunately. As a result it is generally better to get supplements from the manufacturers websites.
There's a lot of ingredients in Protetox and none of them can be properly dosed with one 100mg capsule being a days supply. With exception of the vitamins, but they're not going to do all to much to help you lose weight.
Banaba - there's one early study that suggest banaba can inhibit lipogenesis in test cells,  but this isn't something that is going to make any real difference to weight loss, there's also the fact that it's only one early study and over the years there have been 100s of promising studies like this, that when tried real world applications simply didn't work.
Guggul - Guggul is rich in anti oxidants which protetox claim helps regulate blood sugar, but honestly there are a lot of ingredients that would be more effective, and generally for ingredients like this to have any effect on blood sugar control they need to be in dosages of grams not one ingredient of a dozen that make up less than one gram. There were positive studies in rats, but again this has the same issue. 
Bitter Melon - Bitter melon has only been shown to work in rats  eating a high fat diet, the volume was also quite high, a human body weight size does would be more like 10grams in contrast.
Yarrow - Yarrow is typically something that's supposedly used for an improved immune system, it's mildly diuretic which could lead to a loss of some water weight, but again it doesn't belong in weight loss supplements. 
Gymnema Sylvestre - There's possibly something here that could work in the protetox weight loss supplement, but there's very limited research. In theory it could activate sugar usage in the body, helping maintain healthy blood sugar levels and reducing cravings, but it's a bit of a stretch. 
White Mulberry - There are some studies which suggest that white mulberry could be beneficial  but again they're minimal and nowhere near as well backed as ingredients that aren't in protetox. And usually white mulberry is normally dosed at 1gram 3 times per day to be effective, keep in mind a the size of protetox pills is 1 gram. There can't possibly be enough in here to be effective.
Vanadium - Vanadium is often studied in doses of 100mg for people who have poor blood sugar regulation. It is effective for this, so protetox weight loss supplements could help with food cravings in this instance. It is also possible that it's dosed correctly for it's health benefits, and if we're being charitable, well suggest it is, however, if this is the only ingredient in the protetox formula then that's hardly a glowing recommendation. 
Vitamin C & E - if you're deficient in either vitamin c or vitamin e then there can be negative effects leading to weight gain, however, these are pretty easy to deal with in other ways that will be more beneficial for healthy weight loss.
And apparently there are traces of Licorice, Cinnamon, Cayenne, Juniper Berries, Biotin Pure, Alpha Lipoic Acid, Taurine, Manganese, Chromium, Magnesium & Zinc which are unlikely to be in any beneficial dose.
Protetox is another flash in the pan supplement with a hefty marketing budget, not one that has a great deal of scientific backing. Protetox seems to be a collection of random ingredients relying more on the placebo effect than any proven science. We'd recommend that if you're looking for a supplement that can help you lose weight and want to avoid caffeine then you look for something that contains glucomannan and 5htp, to suppress appetite and other energy boosting ingredients to help handle the subconscious dip in activity that happens when you diet.
Protetox doesn't do any of these things, instead it relies on poorly backed supplements. As a rule of thumb with supplements if it sounds to good to be true, it is. And with weight loss aids specifically, if it sounds very complicated and the manufacturers say it stops you creating fat, or talks a lot about detoxifying, then it's even more dubious.
