SiS Hydro Tablets Cola en Caffeine

Dit is de enige variant in de lijn met cafeïne: 75 mg per tablet, vergelijkbaar met een stevige espresso. SiS Hydro Tablets Cola en Cafeïne combineren de elektrolytenformule van de standaard hydrotablet met cafeïne als extra toevoeging. Handig als je voor een training of wedstrijd zowel gehydrateerd als mentaal alert wilt beginnen, zonder een aparte koffie of energiedrank te nemen. Geen suiker, slechts 3,5 kcal per tablet. Vrij van lactose, gluten en soja.

Wat die 75 mg cafeïne toevoegt

Cafeïne blokkeert tijdelijk de adenosinereceptoren in je hersenen, de stofjes die je slaperig maken bij vermoeidheid. Dat geeft een tijdelijk gevoel van alertheid en verminderde inspanningsbeleving. 75 mg is een bescheiden maar functionele dosis, vergelijkbaar met een stevige espresso. Het is genoeg om effect te merken maar niet zo veel dat het bij de meeste mensen onrust veroorzaakt. Toch: als je gevoelig bent voor cafeïne of dit product laat op de dag drinkt, houdt het je wakker. Gebruik het bewust.

Natrium is niet zomaar een zout

Van alle elektrolyten die je verliest via zweet, gaat het bij natrium om de grootste hoeveelheden. Afhankelijk van je lichaam en de omstandigheden verlies je 200 tot 2000 milligram per liter zweet. Maar het gaat niet alleen om die hoeveelheid op zich. Zonder genoeg natrium houdt je lichaam water minder goed vast. Je kunt flinke hoeveelheden water drinken en toch gedehydrateerd raken, omdat je nieren het vocht snel uitscheiden als er te weinig natrium in het bloed zit. Elk tablet levert 345 mg natrium, in een concentratie van 30 mmol/L in 500 ml water. Die concentratie is niet willekeurig gekozen.

30 mmol/L en de Britse zeilers in Peking

In 2008 vroeg het Britse olympische zeilvaarteam SiS om hulp bij hydratatie. Zeilers zweten flink, ook al lijkt het tegenstrijdig, en vochtverlies bij wisselende weers- en windcondities maakt hydratatie lastig te managen. SiS formuleerde een tablet die precies 30 mmol/L natrium in 500 ml water levert, de concentratie die in wetenschappelijk onderzoek herhaaldelijk beter bleek te werken dan gewoon water voor rehydratatie. Sindsdien is de formule vrijwel ongewijzigd, want die werkt. Vier elektrolyten in elk tablet: natrium, kalium, calcium en magnesium. Niet één, niet twee.

Drie B-vitaminen, een bescheiden maar concrete toevoeging

Vitamine B1, B2 en B6 zijn geen hoofdrolspelers in dit product, maar ze staan er wel in. Vitamine B1 en B2 dragen bij aan de omzetting van koolhydraten naar energie. Vitamine B6 speelt een rol in de eiwitstofwisseling. De hoeveelheden zijn bescheiden: 0,2 mg B1, 0,3 mg B2 en 0,4 mg B6 per tablet, goed voor respectievelijk 18%, 21% en 29% van de dagelijkse referentie-inname. Geen overdreven claims. Gewoon een nuttige aanvulling in een product dat je toch al drinkt.

De cola-smaak onderscheidt zich van de andere varianten door de karamelkleurstof en het ontbreken van groene thee-extract. Voor wie een vertrouwde colasmaak wil combineren met hydratatie en een cafeïneboost voor de start. Niet aanbevolen voor kinderen, zwangere vrouwen of personen gevoelig voor cafeïne.

Great printer...I thought
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
This unit has really great reviews and many from small biz owners who say it works great and lasts. I've had it for a month and I'm really happy with it. It's much better than my last one. If it lasts as so many other reviews say, it's a great purchase. **UPDATE** Loved this printer. Only used it a few times. On the 3rd month, I pushed the button to turn on the printer and there was no response at all. I tried everything. Checked all connections and the outlets. It would not turn on at all. I was out of the return window with Amazon, so I called Epson. They told me they are sending a unit to me and to return mine with the box and label in the shipment. But they said they are NOT SENDING A NEW UNIT, BUT A REFURBISHED UNIT! I am not at all happy about this! I purchased a new printer, not a refurbished printer, and I want a new one! So, I'm really unhappy with Epson right now.

Not a good choice.
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
I recently purchased this printer with high hopes of a reliable and efficient printing solution. Unfortunately, my experience with this printer has been nothing short of a nightmare. Connectivity Woes: The most glaring issue is its abysmal Wi-Fi connectivity. Despite being placed right next to the router, the printer consistently displays a "Poor Wi-Fi Connection" message. This is in stark contrast to all other devices in my home, which work seamlessly with the Wi-Fi network. Even my old laser printer, which is placed close to the same location, functions without any connectivity hiccups. It's baffling how a modern printer can struggle so much to maintain a stable Wi-Fi connection. Scanning Nightmares: The scanning functionality of this printer is equally disappointing. The user interface is far from user-friendly, making it a daunting task to set up scanning to email or computer directly from the printer. This is a basic feature that should be intuitive and hassle-free, but instead, it's a convoluted process that requires unnecessary effort and time. Ineffective Customer Service: I reached out to customer service in hopes of resolving these issues. While they guided me through a reset process, the solutions they provided were only temporary fixes. The problems resurfaced shortly after, leaving me back at square one. It's frustrating to invest in a product only to find that the customer service solutions are inadequate and short-lived. Comparative Performance: What's more perplexing is that my older laser printer, which is from a different brand, continues to perform flawlessly in terms of connectivity and scanning capabilities. This stark contrast highlights the subpar quality of the Epson. Final Verdict: I'm deeply disappointed with this printer and regret this purchase immensely. Its inability to maintain a stable Wi-Fi connection, along with the cumbersome scanning setup and unsatisfactory customer service experience, make this printer a headache rather than a helpful device. I strongly advise against considering this printer if you value reliable performance and user-friendly features. Save yourself the frustration and explore more dependable options on the market.

Easy set up on USB cable. Works as expected on my Windows 11 computer
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
I got this Epson All-In-One printer for my work. I had been using HP printers for years. I started having problems with paper handling on them. Things like getting a paper jam error when there was not paper jammed in it. I decided to try an Epson for a change. I have had the printer now for three weeks. So far it has worked great. Easy to set up on my Windws 11 computer. Works great for printing and for scanning. I have it set up by USB cable because I don't have reliable wireless internet in that part of the building. No issues with the USB configuration. Ink usage seems good so far. Ink on any printer is expensive, but that was expected. I would recommend this printer.

Much harder to install than expected - especially if you have a comma in your Wifi password
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
I found this printer surprisingly hard to install. First, I used the software on the DVD that came with the system. That caused my computer to crash and reboot! After it rebooted, I downloaded the (presumably newer) combo installer from the Epson web site. That ran, but when it came time to connect the printer to the wifi network, I found that there is no way in the Epson network configuration wizard to use a comma in the wifi password. There is a period and many other symbols, but I didn't see a comma. But our system admin used a comma in our wifi password, so I couldn't connect the printer to the wireless network. I had to dig up a LAN cable and plug the printer into a network switch, restart the installation and configure the printer for a LAN connection. That seemed to work, at least according to the installer, but when I tried to print a test page there was a print connection failure. After running the "Epson Printer Connection Checker", it found a printer port error and tried to fix it, but was unable to. So, I removed the printer entirely from the computer using Windows device management and had Windows try to detect the printer. That finally worked, although now the Fax device is missing. But at least now I can print, and the print quality looks good. But I'm still frustrated by the inability to connect to the wifi.

Great printer
Style: WF-4820, Set: 1. SINGLE TRAY (250 sheets)/FAX/ADF/PRINT/COPY/SCAN
This printer is compatible with my Apple Mi 4 desktop and my Apple Laptop. I didn’t have a dvd player, so I went to the required Epsom website, and downloaded the software. No issues. All of the bells and whistles on the printer works flawless. Follow the directions and enjoy the results .
