Why Add Electrolytes to Plain Water?
Drinking high volumes of plain water throughout the day can sometimes flush out vital trace minerals—leading to mild brain fog, muscle tightness, or mid-afternoon energy slumps. Replenishing sodium, potassium, magnesium, and calcium in clean ratios ensures your body actually absorbs fluids at a cellular level.

Frequently Asked Questions
Can I mix electrolytes in my Stanley tumbler every day?
Yes. Food-grade 18/8 stainless steel does not absorb flavors or react with natural citrus citric acid. Just hand wash your lid and straw regularly to prevent residue buildup.
How many packets should I use in a 40oz Stanley?
Most single-serve stick packs are formulated for 16–20oz of water. For a full 40oz Stanley, use 1.5 to 2 stick packs of lighter mixes (like Ultima or Cure), or 1 stick pack of higher-sodium mixes (like LMNT).
Are zero-sugar electrolytes better than regular sports drinks?
For daily desk sipping and routine hydration, zero-sugar options are much better for preventing sugar crashes, dental wear, and unwanted insulin spikes.
