Best Juices for Hydration and Immune Support When Sick
When sick, the best juice to drink when sick is one that replaces fluids, electrolytes, and key nutrients without excess sugar. Clear fruit and vegetable juices with vitamin C, potassium, and natural sugars can support hydration and energy. The CDC emphasizes drinking fluids to prevent dehydration during fevers, vomiting, and diarrhea, and notes that water, broths, and moderate juice intake help maintain electrolyte balance CDC.
For most adults, 4 to 8 ounces of 100% juice per serving is a practical guideline, with total daily fluid intake adjusted for body weight and symptoms. The WHO and many national health agencies recommend oral rehydration solutions for moderate dehydration, but diluted juices can complement these when appetite is low WHO.

Sugar, Electrolytes, and Practical Consumption Guidelines
Sugar concentration matters when sick, because hypertonic drinks can draw water into the gut and worsen diarrhea. The American Academy of Pediatrics and the WHO recommend oral rehydration solutions with specific glucose and sodium ratios, but 100% fruit juice diluted with water (1:1) can be a safe alternative for mild dehydration AAP.
Practical guidelines include sipping small amounts frequently rather than drinking large volumes at once, stopping if nausea increases, and choosing pasteurized juices to reduce infection risk. For children, the AAP advises avoiding sports drinks and undiluted juices, and using oral rehydration solutions as the first line for dehydration AAP.
How to Dilute and Combine Juices for Better Tolerance
Diluting juice with water or electrolyte water reduces osmolality and sugar load while preserving flavor and some nutrients. A common ratio is one part 100% juice to one part water, with a pinch of salt or an electrolyte tablet to replace sodium lost through fever or sweating. This approach is used in many clinical oral rehydration recipes and is endorsed by several hospital nutrition departments.
For people with diabetes or glucose sensitivity, the ADA recommends monitoring blood sugar closely when consuming fruit juices, even 100% varieties, and choosing low-glycemic options such as green vegetable juices mixed with a small amount of apple or carrot juice ADA.
