Fast&Up Reload Electrolyte Tablets, Orange + Caffeine Flavour, 20 Effervescent Tablets, Rapid Hydration & Energy, with Vitamin C & B12, Vegan

I’ve been using the Fast&Up Reload Electrolyte Tablets in Orange + Caffeine flavour for a few weeks now, and I’m genuinely impressed. The fresh, natural orange taste is the first thing that stood out to me—refreshing without being overly sweet, and surprisingly pleasant for an electrolyte supplement. I also love that Fast&Up offers multiple flavours, so there’s always a bit of variety. The price range is fair considering the quality, convenience, and performance of the product. The slim tube design makes them super easy to throw into my travel bag, gym kit, or even take on hikes. Perfect for days when I’m on the go and need something quick. In terms of performance, I definitely feel a difference in my hydration levels. Whether I’m working out, travelling, or just feeling drained, popping one of these into my water bottle gives me a noticeable energy lift and helps me stay properly hydrated. The added caffeine is just the right amount—enough for a gentle boost without the jitters. Overall, a fantastic product that does exactly what it promises. I’ll definitely be repurchasing!

I picked up Fast&Up Reload on a friend’s recommendation because I’ve been trying to stay on top of hydration, especially during workouts and when it’s stupidly hot outside. The tub arrived well sealed and secure — no broken tablets or powdery mess inside, which has happened to me with other brands before. I mainly use these before or after the gym. They dissolve fast in cold water — no lumps — and the mixed berry flavour is actually pretty decent, not overly sweet or fake-tasting. I feel like it really helps me bounce back quicker after a tough session, especially when I’m sweating buckets. I like that it’s got electrolytes plus vitamin C and B12, so it feels like more than just a sports drink. Also nice to know it’s vegan, although that’s not a deal-breaker for me. I’d say these tablets are perfect for anyone active — gym-goers, runners, cyclists — or honestly just if you’re travelling or working long days and don’t drink enough water. I keep a few in my bag for days when I know I’ll need them. Positives for me: they’re super easy to use, taste good, no sugar crash, and definitely help with staying hydrated. Negatives: I guess they’re not the cheapest if you use them every single day, but I usually just have 1–2 tablets max when I really need it. I’ll definitely keep buying them — they’ve replaced the energy drinks I used to reach for, and I feel better not loading up on sugar. If you want an alternative, maybe check out Nuun or SIS tabs — I’ve tried them too but I keep coming back to Fast&Up for the taste and how quickly they dissolve. I’ve added a couple of pics so you can see the tablet size and how they fizz up in water — looks way more appealing than the product photo online. Solid product — does exactly what it says and I actually notice the difference.

Not sure if it’s just the additional water intake after taking the these that’s giving me a hydrated feeling or if these really work. I’ve used quite a few of these hydration tablets and these aren’t the best but definitely not the worst. These take quite a while to dissolve and require a stir to get the final bite to vanish. Taste is ok not great tasting but not a horrible taste either. vitamin content seems reasonably good and better than other alternatives. Feel a slight energy boost after taking them and definitely feel more hydrated. I bought them in offer which made them great value for money however at full price they are similar to other alternatives.

​As someone who spends most of my life feeling like a dehydrated raisin, I've tried a lot of things to get my fluids back up. Most electrolyte drinks either taste like a spoonful of artificial sweetener or have the texture of chalky water. But these Fast&Up tablets are a whole different story. ​They taste genuinely great—a crisp mixed berry flavor that actually makes you want to drink the whole glass. I've used them after workouts, on hot days, and even after one too many coffees, and they work like a charm. I feel re-energized and less like I’m powered by a dying battery. It's truly an electrifying experience. ​My only minor complaint is that when you drop them in the water, you have to wait a little bit for the fizzing to stop. It’s like waiting for a pot to boil when you're already parched, but honestly, it's a small price to pay for what you get. ​Highly recommend for anyone who needs a delicious and effective way to recharge!

I regularly buy these. The taste is nice and really helps with hydration. You get 4 tubes for the money so is a good price.

Tried these as a change from my usual electrolytes and the flavour is actually really nice — peach iced tea is refreshing and not overly sweet. Easy enough to drink and doesn’t have that weird aftertaste some others do. Only downside is they don’t fizz up as well or as quickly as some other brands I’ve used. Takes a bit longer to fully dissolve, even in cold water, which isn’t ideal if you’re in a rush. Still does the job hydration-wise, and the taste is spot on — just wish the fizz was a bit more lively.

Sold! Avid electrolytes user as on Monjaro. Found this product to be extremely tasty. Very surprised due to the cheap price paid during promotion. Definitely purchase again. 5 stars ☀️☀️☀️☀️☀️

I recently tried the Fast&Up Reload – Mixed Berry effervescent tablets for instant hydration and electrolytes, and I’m quite impressed with their effectiveness. They do a great job at quickly replenishing electrolytes and keeping me hydrated, especially after intense workouts or long days. The convenience of the effervescent tablets is fantastic—just drop one in water, and it dissolves quickly, providing a refreshing drink that helps me stay on top of my hydration game. The product delivers exactly as promised in terms of performance and hydration benefits. However, I have to admit that the taste wasn’t quite to my liking. While it’s a mixed berry flavor, it comes off as a bit artificial for my palate. It’s not a deal-breaker, but it's worth noting if you're particular about flavors.
