Older adults often forget to drink enough water throughout the day, which can lead to dehydration. You will be surprised to learn that dehydration is more common in the elderly than it is in younger people. We, young caregivers, are not much concerned about drinking the recommended 6-8 glasses of water a day. We can get by. Such is not the case with seniors. This is where hydration supplements can help. Below, I share the best hydration tablets for the elderly. 

Editor’s note: These tablets are not meant to be swallowed. You can put them in water, fruit juice, or smoothies. They dissolve in two minutes.

The best thing about this hydration supplement is you get an assortment of four exciting flavors: Lemon Lime, Orange, Strawberry Lemonade, And Tri-berry. Each flavor comes in a separate container. 

Each container contains 12 tablets, which makes it 48 total servings. 

You can add one tablet to a cup/sipping bottle filled with 16 ounces of water. The tablet dissolves quickly, although I recommend you stir it with a spoon or give the bottle a good shake. 

The drink gives off bubbles and is a little fizzy. The flavor is perfect for older people who have an affinity for fizzy drinks such as Coke or soda. The drink tastes great after a workout session or a long walk in the park.

Can a person with Dementia benefit from hydration tablets? 

It is safe for a person with Dementia to take hydration tablets by dissolving them in water. Caregivers must prepare the solution themselves, and monitor while the person with Dementia gulps the hydration drink down. 

How much electrolyte solution should I drink daily? 

A healthy adult needs 1,600 to 2,000 mg of electrolyte water a day, says a report by the National Research Council (US) Subcommittee. You don’t have to fulfill all your daily electrolyte needs from a hydration solution. 1-3 servings of hydration tablets should suffice for an active senior person.

What causes an electrolyte imbalance in the elderly?

Electrolyte imbalance can occur in a person if they have too much or too little water content in their body. Dry mouth, tiredness, dizziness, vomiting, nausea, etc are some of the symptoms of electrolyte imbalance, confirms a report by the MedicalNewsToday. 

How long does it take for electrolytes to work?

It depends on how low you are on your electrolyte levels. It will take a few minutes for a dehydrated person to feel good upon taking electrolytes. The primary job of hydration tablets is to speed up the process of water absorption in the body. On the other hand, it will take more than a day to replace the entire electrolytes in your body. 


As people get older, their thirst detectors begin to function intermittently. They do not realize when they are thirsty. They may go hours without drinking water, which can certainly lead to tiredness, fatigue, irritability, and in some cases more severe health issues. This is why it is important to keep yourself hydrated at all times. An elderly person can stay hydrated by taking hydration tablets with water. These tablets contain natural electrolytes, mixed with food-derived vitamins and minerals. They have no side effects.
