Chogan Dren Fast is a liquid food supplement from the SuppleFit line, sold as a draining drink: a pineapple-flavoured concentrate you dilute in water and sip through the day. It comes in two versions, a box of 30 ten-millilitre sticks and a 300 ml bottle, and the brand’s dose is one stick per litre of water. The price sits between about 39 and 44.90 euros depending on format and reseller (indicative EU figures, July 2026). This article covers what is in it and how it is taken, and it is straight with you about what can and cannot be said about the effects.
Interest declared: I sell Chogan products. It would be easy to oversell this one, so I am sticking to what the label says and what EU rules let me claim.
What is Dren Fast?
It is a concentrate for dilution, part of Chogan’s SuppleFit supplement line, in the category the brand calls weight balance. It is not a tea or a medicine, and it does not replace a meal.
The two formats in the catalogue:
| Format | Contents | Indicative price |
|---|---|---|
| Stick box | 30 x 10 ml sticks (300 ml total) | ~39 EUR |
| Bottle | 300 ml | ~44.90 EUR |

On the composition, the ingredient the brand leads with is Equitullas, a patented complex of pineapple (stem, with bromelain), birch and horsetail. Alongside it the label lists water, vegetable glycerine, maltodextrin, magnesium citrate, burdock, orthosiphon, grape extract, Centella asiatica, green tea, melilot, guarana, vitamin C, folic acid, acidifiers, preservatives (potassium sorbate, sodium benzoate) and sucralose. A source reproducing the label gives around 20 mg of caffeine per stick, which comes from the guarana.
To be straight about one thing: promotional copy also mentions artichoke, asparagus and fig. Those three do not appear on the ingredient panel I was able to verify, so I treat them as marketing text rather than composition.
What is it for and how do you take it?
The instruction is simple: one 10 ml stick diluted in 1 litre of water, drunk across the day. Shake before opening. With the bottle format the logic is the same, measuring out the equivalent dose.
In practice, what the product genuinely does is flavour a litre of water and build the habit of drinking it. That on its own is the most useful effect I can attribute to it without overstating anything: plenty of people drink very little water during the day and end up finishing a litre because it tastes of something.
As for the functions the brand attaches to it (fluid drainage, a feeling of lightness, support for weight balance), those are the brand’s positioning. In the EU, health claims for these botanicals in a drainage or weight-loss context are not authorised, and some remain under assessment. I would rather you heard that from me than found it out after spending 40 euros.
Does Dren Fast work? My review
It depends entirely on what you expect from it, and this is where I want to be clearer than most descriptions you will run into.
If you expect to lose weight, no. That is not what it is for, and no supplement replaces food and movement. None of the botanicals in the formula carries an authorised EU weight-loss claim.
Fluid retention is harder to answer. Feeling less puffy is an effect the brand states and one I cannot present to you as proven. Some of my customers like it and say they notice a difference within a week; others find it does nothing much for them. I know of no independent trial on this specific product that would settle the question.
If what you want is to drink more water and fewer soft drinks, it works well. That is the use I actually recommend: a litre of pineapple-flavoured water instead of two soft drinks is a trade with a real effect.
Two cautions before you buy. It contains caffeine, not much, but it does: if you are sensitive, avoid it late in the day. And as with any supplement, if you are pregnant, breastfeeding, on medication or managing a health condition, talk to your doctor or pharmacist before starting. That is not legal boilerplate, it is what I would tell a friend.
The SuppleFit line is described as nickel-tested, paraben-free and not tested on animals. Those are brand statements at line level, with no certification I can confirm for this particular product.
Price and where to buy
Like every Chogan product, Dren Fast is bought through an independent consultant or through the online shop tied to their code. There are no brand shops and it is not sold in pharmacies. I covered all the routes, with timings and things to watch for, in the guide on where to buy Chogan perfume, which applies to the rest of the catalogue too.
On price: 39 euros for a box of 30 sticks works out at roughly 1.30 euros per daily dose if you run the full month. That is the benchmark to compare any alternative against before you decide.
If you are looking at Chogan for personal care in general rather than supplements specifically, I wrote about the snail slime line in the same spirit, and real customer feedback is gathered in Chogan reviews.
My verdict
So, buy it or not? Buy it if you want a pleasant reason to finish a litre of water a day and you can live without proof of anything beyond that, because the drainage functions the brand attaches to it carry no authorised EU health claim. Skip it if you are hoping it will do the work of a diet. At roughly 39 to 44.90 euros a month, that is the whole decision.
