Thorne Research Daily Electrolytes Review

The main ingredient here is salt, which supplies chloride and sodium. The best direct evidence is small but positive. In 10 men resting at high altitude, a salt and citrate drink restored blood plasma volume better than plain water ^[1]. In 12 female cyclists and triathletes exercising in the heat, a salt drink taken 2 hours beforehand helped the body hold more fluid and lose less weight than a placebo drink ^[2]. Most other chloride studies tested salt water given into a vein to protect hospital patients' kidneys from contrast dye, with mixed results, and they do not speak to everyday hydration ^[3][4]. The magnesium is a trace amount, far below the 800 milligrams used in the trial where cells held more water, and that trial also gave creatine, so magnesium alone cannot be credited ^[5]. A 200 milligram dose eased bloating in women only after two months ^[6]. For calcium, the only study was in women past menopause and did not test hydration ^[7]. For potassium, two small studies in men did not show that it improves hydration ^[8][9]. Animal and cell studies are never counted.

Magnesium is the main ingredient here, and nearly the whole panel spoke about it: about half use it themselves and most of the rest recommend it. The most common reason is sleep, with several taking it before bed, though one panelist says the evidence for sleep is not yet consistent and another says it does not fix waking in the night. Preferred forms are glycinate and L-threonate, with 400 mg before bed named by three panelists and others giving ranges of 300 to 600 mg a day, while some use electrolyte drinks with sodium, potassium and magnesium for workouts and fasting. Other reasons given include muscle cramps, blood pressure, constipation and bone health, and one panelist cautions that some labels list the whole compound weight so the real magnesium dose is much lower than it looks. Potassium, a smaller ingredient in this product, is backed by two panelists, one who prefers getting it from foods rather than supplements; no one said they stopped taking anything.

Combine with: For hydration use, pair with a quality multivitamin or B-complex and adequate plain water; vitamin C and a small amount of carbohydrate can aid absorption during intense exercise. If the real aim is blood pressure support, consider a sodium-free approach such as magnesium glycinate or taurate (200-400 mg), potassium from food sources (leafy greens, beans, bananas, avocado) rather than high-sodium mixes, omega-3 fish oil (EPA/DHA), CoQ10 (100-200 mg), and possibly beetroot/nitrate or hibiscus extract. Those with kidney disease or taking meds, ARBs, or potassium-sparing meds should consult a clinician before adding potassium or magnesium supplements.
