Can Electrolytes Help Me Recover from a Hangover?

(What the Science Really Says)
A night of drinking can leave you feeling drained, foggy, and dehydrated. But what exactly is happening in your body — and can electrolytes actually help?
Let’s explore the evidence behind how alcohol affects hydration and whether replenishing electrolytes can support recovery from a hangover.
The Biology of a Hangover
Alcohol is a diuretic, meaning it increases urine production. It does this by suppressing the hormone vasopressin, which normally helps your kidneys retain water. This leads to greater fluid loss and the excretion of electrolytes — such as sodium, potassium, and magnesium — via urine.
Dehydration and electrolyte imbalances are widely believed to play a role in some hangover symptoms, including:
Headache
Fatigue or weakness
Dizziness or lightheadedness
Muscle cramps
While hangovers involve other processes too — such as immune system responses, acetaldehyde buildup (a toxic alcohol metabolite), and blood sugar fluctuations — hydration status is one modifiable factor supported by clinical research.
🔬 A 2000 review in the Annals of Internal Medicine notes that alcohol-induced dehydration may contribute to hangover severity, particularly symptoms like thirst, fatigue, and headache.
Can Electrolytes Help?
Electrolytes are minerals that help regulate fluid balance, nerve function, and muscle activity. When you lose fluids and electrolytes through increased urination (or sweating, exercise, or illness), your body’s ability to retain and use water is impaired.
Research into oral rehydration therapy (ORT) — used for decades in clinical settings to treat dehydration — shows that combining water with electrolytes is significantly more effective than water alone for fluid absorption (World Health Organization guidelines, 2005).
While specific clinical trials on electrolytes and hangover recovery are limited, replenishing fluids and electrolytes is widely recommended as part of general hangover management. It may help reduce dehydration-related symptoms and restore a sense of balance.
Where HYDRO-SALTS Comes In
HYDRO-SALTS is an electrolyte infused with vitamins and formulated to support hydration. It contains:
Sodium – A key mineral for water absorption
Potassium – Supports muscle and nerve function
Magnesium – Involved in energy metabolism and may help with fatigue
Chloride – Helps regulate fluid and acid–base balance
Zinc and bicarbonate – Commonly included in hydration support products
While HYDRO-SALTS is not a medical treatment for hangovers, it may aid hydration and electrolyte replenishment, especially when taken alongside water and rest.
Best Practices for Hangover Recovery
Before Sleep: If possible, hydrate with electrolytes and eat a light snack.
Morning After: Sip fluids with electrolytes, eat a simple, nourishing breakfast, and rest.
Throughout the Day: Continue hydrating steadily — not all at once.
The Bottom Line
Hangovers are caused by a mix of biological processes — not just dehydration — so there’s no single cure. However, supporting your hydration and electrolyte balance may reduce certain symptoms and help you feel better, faster.
💧 If you’re looking for a simple way to support hydration after a night out (or during any demanding day), HYDRO-SALTS offers a scientifically grounded option without compromising on flavour.
