From The Clinician’s Bench

We are not in the business of encouraging anyone to drink. But people do — and when they land in Dr. Courseault’s clinic feeling wrecked the next morning, they deserve an honest, physiology-first answer instead of folklore. Here is what a hangover actually is, what the peer-reviewed literature says about sodium, tyrosine, taurine, and ginger, and why those four ingredients ended up together in CoreSalt™.

01 · What A Hangover Actually Is

A hangover is not simply “dehydration,” and it is not one single thing you can switch off. The current scientific picture describes several overlapping insults that arrive together. Alcohol suppresses vasopressin (antidiuretic hormone), so the kidneys stop holding onto water and you lose fluid and electrolytes — sodium first, then potassium and magnesium. At the same time, ethanol is metabolized into acetaldehyde, a reactive toxin that drives oxidative stress before it is cleared. On top of that, the body mounts a low-grade inflammatory and immune response, and sleep, blood-sugar regulation, and neurotransmitter balance all take a hit.

Interestingly, when researchers measured blood and urine markers, dehydration alone did not predict how bad someone’s hangover was — the immune/inflammatory response tracked severity most closely (Penning & Verster, Curr Drug Abuse Rev, 2010; van de Loo et al., 2020). That is the honest starting point for anyone selling a “hangover fix”: because the cause is multi-factorial, no capsule neutralizes alcohol or erases a hangover. What a well-built formula can do is support the specific, measurable losses and stresses alcohol creates — which is exactly the lane CoreSalt™ was designed for.

02 · Sodium & The Core Electrolytes

Because alcohol switches off vasopressin, you urinate more than you take in and dump sodium, potassium, and magnesium along with the water. Plain water alone rehydrates slowly, because water follows salt — sodium is what actually pulls fluid across the gut wall and back into the bloodstream. This is the well-established principle behind oral rehydration: a small amount of sodium (and glucose) dramatically speeds how fast water is absorbed compared with water alone.

The American College of Sports Medicine’s position stand on fluid replacement remains the foundational document on why sodium and potassium — not just fluid volume — are what restore normal fluid balance, blood pressure, and nerve and muscle function after heavy fluid loss (Sawka et al., Med Sci Sports Exerc, 2007). It is worth being precise, though: controlled work shows that drinking water helps thirst and dry-mouth but does not by itself abolish a hangover — hydration and hangover appear to be co-occurring but largely independent consequences of drinking (Mackus et al., Alcohol, 2024). Electrolytes address the fluid-and-mineral part of the morning — the lightheadedness, the cramps, the wrung-out feeling — which for many people is the most miserable part.

This is the core of CoreSalt™: sodium, magnesium, and potassium in a taste-free capsule, so you can rehydrate with plain water rather than forcing down a salty drink when your stomach is already unhappy. See how the full CoreSalt™ formulation is built, and for a heavier reset the clinic also offers IV Hydration Therapy.

03 · Tyrosine

Part of a hangover is not in your stomach — it is in your head. The mental fog, the flatness, the can’t-focus feeling. L-tyrosine is the amino-acid precursor the body uses to build dopamine and norepinephrine, the catecholamine neurotransmitters that drive alertness, motivation, and working memory. Under stress, fatigue, and sleep loss — the exact conditions of a hungover morning — these neurotransmitters get depleted faster than the body replaces them.

A systematic review found that supplemental tyrosine helps preserve cognitive performance — working memory, decision-making, mental processing — specifically when the brain is under stress or short on sleep and its catecholamines are temporarily run down (Jongkees et al., J Psychiatr Res, 2015). Notably, tyrosine tends to help most precisely when the system is depleted — which is why it earns a place alongside the electrolytes rather than in place of them.

04 · Taurine

Taurine is one of the most abundant free amino acids in the body, concentrated in the heart, muscle, and brain, where it participates in fluid balance, cardiovascular function, and the response to physical stress. In athletic and recovery research, a meta-analysis supports taurine’s role in endurance performance and exercise recovery (Waldron et al., Sports Med, 2018).

More directly relevant to drinking: much of a hangover’s toxic load comes from acetaldehyde, the reactive intermediate produced when the body breaks down alcohol. Mechanistic studies report that taurine can support the activity of aldehyde dehydrogenase (ALDH) — the enzyme that clears acetaldehyde — help blunt the rise in acetaldehyde after alcohol, and bolster the liver’s own antioxidant defenses against the oxidative stress that acetaldehyde generates (Wu et al., Food Chem, 2011). A more recent randomized, double-blind, placebo-controlled trial on post-alcohol discomfort found taurine-related metabolism and antioxidant regulation among the pathways involved in feeling better afterward (randomized controlled trial, 2024). It is worth being candid that much of the acetaldehyde-clearance data is preclinical — but the mechanism is biologically coherent and low-risk, which is why taurine is a longtime fixture of recovery formulas.

05 · Ginger

Nausea and an unsettled gut are, for many people, the defining feature of a hangover — and they are also what make it hard to keep down the water and minerals you actually need. Ginger (Zingiber officinale) is one of the best-studied botanicals for nausea, with randomized-trial evidence across post-operative, chemotherapy-related, and pregnancy nausea (Ernst & Pittler, Br J Anaesth, 2000).

Its active compounds — gingerols and shogaols — also contribute to the body’s normal antioxidant and anti-inflammatory response, which connects back to the inflammatory side of a hangover (Mashhadi et al., Int J Prev Med, 2013). In CoreSalt™, ginger is there for a practical reason as much as a pharmacologic one: it helps the capsule sit easily on a sensitive stomach, so the electrolytes and amino acids can do their job.

06 · How To Use It Around Drinking

The physiology points to a simple pattern. Before and during: hydrate with water and replace electrolytes as you go, rather than waiting until the losses have piled up — you are getting ahead of the fluid and mineral deficit. The next morning: rehydrate again with electrolytes to restore balance, and let the ginger settle your stomach and the tyrosine support your focus while your body finishes clearing what’s left. Eat, and sleep as much as you can — no supplement substitutes for either.

Because CoreSalt™ is dosed for the individual patient, Dr. Courseault sets timing and amounts in clinic based on your diet, your medications, and your situation. Sodium and potassium can interact with blood-pressure medicines, diuretics, and kidney conditions — so this is a conversation, not a guess.

07 · Honest Answers To Common Questions

Does CoreSalt™ cure a hangover?

No — and be skeptical of anything that claims to. The most rigorous review of hangover interventions found no product that reliably eliminates a hangover, and concluded the only sure prevention is drinking less or not at all (Pittler et al., 2005). What CoreSalt™ does is support the specific, well-characterized losses alcohol causes: fluid and electrolyte depletion, catecholamine drain, acetaldehyde-driven oxidative stress, and GI upset.

If dehydration doesn’t predict hangover severity, why bother with electrolytes?

Because “hangover severity” and “how you feel” aren’t the same measurement. Rehydration and mineral replacement won’t undo the inflammatory response, but they directly address the lightheadedness, cramps, and drained feeling that come from losing sodium, potassium, and magnesium — the part patients most often want relief from.

Is this the same as a sports drink or an energy drink?

No. CoreSalt™ is a taste-free capsule with no sugar, artificial sweeteners, or artificial colors, taken with plain water — not a sweetened beverage. It is manufactured in an NSF-certified facility and dosed clinically rather than marketed as a party product.

The reference list is illustrative of the literature underpinning the role of each ingredient and is not exhaustive. Several mechanistic findings (particularly for taurine and acetaldehyde) derive from preclinical models. CoreSalt™ is a dietary supplement; these references describe the role of individual ingredients in the published scientific literature and are not claims about the product itself.
