Jadera is one of the most attention-seeking products on the market. This might be an unusual title to hand out, but it’ll become clear when we discuss this product in detail.
It’s an example of how a supplement company attempts to pad their product with so many different ingredients that two things start to happen:
- They get a lot of attention initially because of the number of ingredients they can flaunt/get noticed for
- They’re so under-dosed on each individual ingredient that they dilute their overall effect and become utterly worthless.
These are consistent themes we’re going to pick up on in this piece, but to start with, its clear to us that there’s a lot going on with this supplement – probably too much.
There’s a significant amount of junk in this product, and so many ingredients hidden behind the proprietary blend that there’s really not much of a dose of anything.
We’ve seen the importance of dose-response relationships with ingredients like garcinia cambogia and raspberry ketone before (spoilers: they’re both useless in supplementary doses). With a reduction in active ingredients, this product may be diluted down beyond the functional value it might have had in the first place!
What is Jadera?
We’re not sure, and we don’t think that Jadera is either!
The basic idea behind the supplement is that it’s a fat loss and “slimming” pill. It’s a bit non-descript, but the theme of the ingredients are a variety of plant-based compounds aiming at everything from weight loss to vitamin deficiency and beyond.
There’s neither a unifying theme to the ingredients nor a discernible reason to use the supplement. “Slimming” is incredibly vague, with a combination of mental and physical wellbeing compounds, as well as some obscure herbs that have very mixed scientific efficacy. Overall, the product seems a bit undecided on what it wants to be/do.
The Physical Effects
This is obviously the point, as a slimming product is geared towards improving body composition in some way.
To start with, it contains an extensive B vitamin complex, which is a positive choice given the extensive positive effects of vitamin B and how difficult they can be to get into the diet . There are benefits to metabolism, blood and energy transfer from these vitamins.
Are they going to be useful to the average joe who isn’t deficient though? Well, that’s unclear. Some of these compounds are effective above and beyond fighting deficiency, making them a great supplementary choice. There might be some benefits, but we can’t say this for all of them – especially not in relation to fat loss specifically.
It’s confusing that this product contains so many different things, but no caffeine. Instead, it opts for a much gentler stimulant in the form of bitter orange. This is a common ingredient on the market, even though the science clearly shows that it's far less effective than caffeine for everything from weight loss to energy and focus. We’re not sure what it’s here for, but it’s definitely not our first choice.
The various herbs that are involved in this product are not aimed at weight loss, nor are they proven to achieve anything like accelerated fat-burning. They’re ‘traditional medicine’ compounds that have been put together in order to make people feel better, rather than actually make positive changes. Feeling better is always good (duh), but these ingredients do not reliably contribute to weight loss.
The science has yet to prove any positive effect though, especially compared to existing alternatives like the unusually-absent caffeine.
The Mood Boosters
There are a few compounds in Jadera that strike us as being relatively effective in the pursuit of happiness. These are mood-boosting compounds that aim to provide the building blocks for key neurotransmitters Dopamine and Serotonin.
These essential brain-chemicals are the triggers for happiness and joy, and a bunch of other feelings and emotions that overlap with them. This is why Jadera has a number of positive reviews related to feeling better. Definitely a worthwhile goal, but it does make us wonder why this is marketed as a slimming pill when it contains a single (relatively ineffective) weight-loss aid and so many general wellbeing support compounds.
Dopamine is one of the two key chemicals behind happiness. It’s the one associated with pure joy and elation, the kind you experience during enjoyable social interactions and other forms of fun. It’s the driving force behind raw-positive emotions.
You can’t just eat dopamine to get happier, however. Your body breaks down dopamine and other forms of unusual chemicals in the digestive system. What you can do is consume L-Dopa, an amino acid that provides your body with the raw materials to produce dopamine later on .
This is what Jadera does by including L-Dopa, further proving that it is not a slimming pill at all. It’s a wellbeing pill that has an unusual overlap with herbal supplements and B vitamins. It might obscure the point of the product, but it definitely brings key benefits.
Serotonin is a key compound in producing the kind of happiness that we experience in response to achieving tasks and other forms of social achievement. It’s not about playing with a puppy, but more likely to be released when you achieve something that you consider meaningful – like a tough project or a promotion.
5-HTP is the same type of pre-drug that L-Dopa is  – it’s a key player in the organic development of more serotonin in the body. It’s another way of addressing stress-related problems, though it’s important to control your intake as serotonin is related to fatigue and the more you produce, the greater the length of fatigue you are likely to experience.
The levels in this product aren’t clear, but they’re not going to cause a problem. We expect that you might experience a general improvement in mood, though with the dosings as they stand its unlikely that they’ll cause any problems or be particularly obvious.
Jadera’s Ingredient Problem
The real problem with Jadera is that it contains a mixture of ingredients that don’t contribute to the problem it aims to address: body fat and obesity.
The number of ingredients included, and the overall weight of each pill, suggests that there’s going to be a serious problem fitting in an effective dose of the active ingredients. This is a serious problem: if the ingredients in this product are at 70% doses, you’re going to fall below the necessary levels to get the benefits.
This is obviously a problem as it could quite easily reduce the effect of all of these compounds. Jadera also suggests taking 4 pills per day, which is an easy way to burn through your purchase in a few weeks and become dependent on Jadera for mood adjustments.
We’re not sure this is a sustainable model and, given the lack of proven effect on weight loss, we’re not big proponents of this supplement as a way of addressing/controlling body fat.
The only thing to say about Jadera is that it is not a weight-loss supplement. Despite selling itself as a slimming pill, the whole host of effects that Jadera has is effective at improving wellbeing and mood.
These are valuable in themselves, but the effects that they have on weight loss and ‘slimming’ are slight and unreliable. Jadera claims that L-Dopa is the cause of these benefits, but they’re clearly small, indirect results of a better mood!
If you can look past the trashy website, Jadera isn’t bad for those purposes. However, we have to look at it based on the effects its aimed at and, as a slimming pill, this has absolutely no real benefits. At any price, this is a rip-off. If you want a wellbeing pill it’s a 3/5, but if you want fat loss, it’s a 1/5!
