Potassium is an abundant mineral in the human body, which is needed to perform essential physiological processes. It plays a part in the transmission of nerve impulses, muscle contraction, maintenance of normal kidney function, and is especially important for regulating normal heartbeat.*

Like other minerals such as sodium, calcium, and magnesium, potassium is an electrolyte that is necessary to send electrical nerve impulses to the muscles. One very important muscle is the heart, of course. Healthy potassium levels have been linked to reduced blood clotting and efficient opening of blood vessels, both of which are important for maintaining blood pressure.*

Diets rich in potassium help to dissolve calcium deposits in the kidneys. This promotes clear passageways in the urinary tract.*

Ingredients
Potassium (from potassium gluconate), gelatin (bovine) capsule

Suggested Use
Take 1 capsule, preferably with a meal or as directed by a healthcare professional.

Store at room temperature. Keep out of reach of children.

 

Frequently Asked Questions
Q: What is the capsule size?
A: Capsule size 00.

Q: What type of capsule does this product come in?
A: This comes in a gelatin capsule. The gelatin is derived from bovine hide (beef skin).

Q: Why does each capsule provide only a small percentage of the recommended daily allowance for potassium?
A: Sadly, we are limited by the size of the capsule. There is a limit to how much raw material we can fit inside each capsule. Minerals such as potassium, calcium, and magnesium in raw material form take up a lot of space and only supply a small fraction of the elemental amount that we can claim on the label.

We don’t outsource to the lowest bidder.

Guaranteed Authenticity: Every batch of Potassium is carefully sourced and undergoes rigorous testing for ID, purity, potency, and microbiology before, during, and after manufacturing.

Just Pure Ingredients: At Dr. Clark Store, we stand against adulteration. Our rigorous testing reveals that an estimated 30% of bulk supplement powders in the U.S. market contain added fillers and/or come from incorrect species or plant parts. Unlike importers who operate according to FDA 21 CFR 117 and often rely on analyses done by the manufacturer abroad, we conduct thorough tests on all incoming materials in our full-size laboratory, guaranteeing the integrity of our products.

Carrageenan and Surfactant-Free Capsules: FDA regulation 21 CFR 101.100(a)(3)(ii) allows manufacturers to avoid disclosing ingredients in food if present at “insignificant” levels. This is why "Veggie Capsules" may contain carrageenan. Dr. Clark Store ensures the use of only the finest BSE-free gelatin capsules, free from carrageenan, surfactants, and prion risks. Our dedication to purity dates back over 30 years, ensuring safety and quality in line with Dr. Hulda Clark's original vision.

No Magnesium Stearate and No Hidden Processing Aids: True to Dr. Clark's vision, we never use magnesium stearate or any toxic processing aids in our products. Our commitment to transparency means all ingredients are clearly declared on the label, offering you peace of mind and a product you can trust. Again because of FDA’s lacking regulation 21 CFR 101, many brands contain magnesium stearate without it being declared on the label.

Verifiable GMP Certification: Trust is earned, not given. That's why we back up our GMP certification claims with verifiable evidence. Partnering with VeriGMP®, a UL-certified company, we adhere to strict GMP quality systems, ensuring that each product meets the highest standards of manufacturing and quality assurance.

Epson is Epic!
This review is for the Epson EcoTank ET-2903 All-in-One Color Supertanker Printer. I am having a difficult time finding enough superlative words to describe how awesome this printer is. Let me begin by saying this printer blows any competition out of the water. I have personally owned several, highly touted, printers in the past four years and either they have underperformed, had complications or had major connectivity issues. They were a source of constant frustration. Then, I was able to procure an Epson EcoTank printer in the office where I work and have loved it. So, when I saw this Epson ET-2903 EcoTank, I did not hesitate to order it. Out of the box, you receive an all in one printer, a very precise set of instructions, and 4 bottles of high quality ink in Black, Cyan, Magenta, and Yellow. The printer is designed to work with the Epson Smart Panel app which guides you effortlessly through the installation and printer initialization process. Epson made this process very easy to set up, even for someone not very tech savvy. With the app, you can use your computer, laptop, tablet or mobile phone to print wirelessly to your printer. The difference with this EcoTank printer versus ink cartridge/toner printers is that each color ink has a separate refillable tank well that uses fluid ink. My office Epson EcoTank ink lasts and lasts and lasts and is very economical. I expect this ET-2903 will ink will last as well. I printed out my initial test page and all is working perfectly. I then printed out a color wheel to test the colors. It printed vibrant, beautiful colors in only seconds with the capability of printing 11 pages per minute. The printer is equipped with a scanning bed to easily scan and print any documents or photos. You can also scan an import any document/picture directly to your mobile phone, tablet or computer. One of the things I have learned about printers with ink tanks is that because they use liquid ink, they work a little differently from standard ink cartridge printers. Each color tank has tubes that run from the tanks to the printhead, providing excellent quality prints each time. However, an issue with this type of printer can be that they can occasionally get clogged if they sit idle for long periods. To prevent this, under the maintenance option on the control panel, I run a nozzle check periodically that takes only seconds to run. If it appears that there is a clog, the maintenance menu has a printhead self-clean option for easy cleaning. I was impressed with how lightweight the printer is and the dimensions are perfect for smaller areas. I measured the printer to be approximately 14.2” Length x 12.5” Deep x 6.4” High and can easily sit atop a desk, printer cart or shelf. Epson got this printer right and I can honestly say if you are looking for an economical, easy to use and reliable printer, you can buy this printer with confidence. With one click on my phone, I said goodbye to clunky disposable ink cartridges that are environmentally unfriendly, and hello to refillable tanks when I placed my order. I am thrilled with this printer and wholeheartedly recommend it.

Well Designed, Prints Clearly and Accurately, Software is a Bit of a Pain To Set Up
I've never used a printer in my entire life that didn't use finicky ink cartridges that are almost more expensive than the printer itself and need to be constantly replaced; this is a breath of fresh air, despite the dangers of spilling ink and making a mess. I found filling this with ink to be really easy, since you only have to pout the ink bottle in the correct port and leave it to fill itself, which takes about 10-15 seconds. the included ink bottles really only give you enough for a complete fill: You fill it, the printer set up charges the printer with ink, and the remaining ink in the bottles can refill about to the "max" line. Still, I really like this method. The top of the printer pops open like the hood of a car, to access the filling ports. It then has to be lowered down in two stages, presumably to prevent dropping the lid on fingers, though it doesn't seem heavy enough to cause major damage to adult fingers, and I have the printer elevated away from little fingers. This thing has the tiniest little LCD screen! It's a bit tricky on the Epson website to determine which software you need specifically. Obviously, my goal is to have a wireless printer for the entire home network. Some of the software seems specifically web-based, so you could theoretically print from work to a home printer, etc., though I balked at setting up or using an email address to send print jobs to. The wireless was annoyingly tricky to set up. I am still not sure if you're supposed to connect a computer and the printer to the wifi separately, or the printer first and then the computer would automatically recognize it, or what. I did successfully connect the printer to the wifi, but couldn't install some of the Epson software - it kept failing - but a quick test did allow me to print wirelessly, so I decided to just call it good and be done. Everything I have printed has been very clear and crisp. It could be a little darker and have more contrast, but that may be how I printed, or printing from pdf. It printed without jamming or sticking, and everything came through quickly and accurately, without leaks or streaks on my paper. I haven't tried the photocopier function though, since I mainly need it for printing and not scanning.

No automatic double sided. Bulky external paper tray
Set up was easy. I didn’t like the exterior paper storage. The whole printer was slick and stealthy until it got to that obnoxious tray. Set up was easy. Printer does not have automatic duplex capabilities you have to manually flip the paper to do double sided. I also didn’t think the printing quality was great.

Sorry, Brother. Epson smashed you.
I have been a long time Epson user. I have owned their printers, all-in-ones, movie projectors, and even a receipt scanner. In all cases, I have always found them to be the best performance per dollar of any of the big guys. There kind of like Panasonic in cameras where people may talk about some other big names, but what you get per dollar is always good from them. Somewhere along the way, I got disillusioned with companies charging me $60 per pack of ink. I'd get really mad when I couldn't print black text because red or something was out. For a few years, I gave up and just went black and white laser printer. The toner was dirt cheap, and my printing cost dropped to virtually nothing. But, my ability to pront pictures was gone. No more color at all. I'd have to go to a print business if I needed color copies. Well, this finally changed that. The EcoTank is a great design. The "Eco" stands for the economic cheap ink it takes, and the "Tank" refers to the big holding tanks for the ink and give long ink life. Epson probably makes the best ink, but many manufacturers sell inks for this printer. There's none of the stupid compatability issues with cartridges. It's 2026, so of course it all connects wirelessly over WiFi. It's wonderful. The only issue is that you might have to do a little more maintenance to keep it reliable. If you let old ink carts sit too long, you could just replace them. Here that isn't an option. I've seen Youtube recommendations that say you should probably print a color page every week or two, so factor that in to keep it running well. I love it. Five stars.

Solid Printer for Regular Use
I ordered this Epson EcoTank ET-2903 because I wanted a printer that did not make me feel held hostage by tiny ink cartridges. The refillable tank system is the main reason this printer stands out. Being able to see the ink levels on the front and refill from bottles makes the whole process feel less wasteful and less stressful. Setup was straightforward. Filling the ink tanks was easier than I expected because the bottles are keyed to the right color, so you are not guessing where each one goes. I did not have a mess during setup, and that was my biggest concern with a tank printer. Print quality is strong for normal home and office use. Black text comes out clean and easy to read, and color prints are bright enough for school projects, labels, recipes, forms, and casual photo printing. It is not the fastest printer I have ever used, but the tradeoff is lower ink stress and better long-term value. The wireless printing is convenient once it is connected. I like being able to print from my phone or laptop without moving files around. The scanner and copier are also useful for everyday paperwork, receipts, and documents. A couple practical notes: this is a rear-feed paper tray style printer, so plan where you are putting it because it needs some clearance. Also, it does not automatically print double-sided, so duplex printing takes a manual flip. For value, the ink tank system is what makes this worth it. If you print regularly and are tired of buying cartridges, this is a smart home office upgrade.
