Liquid I.V. Hydration Multiplier Lemon Lime Review
The page presents Liquid I.V.® Lemon Lime Hydration Multiplier® Powdered Electrolyte Drink Mix in a 15 count packet format, sold by the Liquid I.V. store on Walmart. The listing's key item features describe it as a hydration mix, a non-GMO electrolyte drink mix that the page says delivers hydration faster than water alone. The page describes the Lemon Lime flavour as zesty and bright, with a punch of citrus flavour. The product is said to be powered by LIV HYDRASCIENCE™, which the page describes as an optimized ratio of electrolytes and clinically tested nutrients. According to the listing, Hydration Multiplier® contains three times the electrolytes of the leading sports drink, along with eight vitamins and nutrients. The page states that it contains 100% of the daily value of four B vitamins: B3, B5, B6 and B12. The product is presented as convenient, with single-serving, travel-friendly packets that are easy to enjoy on the go. The listing instructs buyers to pour one easy-to-open packet into 16 oz of water, then mix or shake and hydrate. The page also describes a hydration aid commitment: since 2015, the company says it has donated over 55 million servings of Liquid I.V.® to people in need around the globe, and donates over 1% of its revenue to its Impact programs. The rating shown on the page is 4.7 out of 5 stars from 3,877 ratings. The page does not show a written review section, a star breakdown, a current price for this exact listing, an ingredients list, or a printed barcode in the scraped text. Related products shown on the page include other Liquid I.V. flavours and sizes, but these are separate listings and are not the product described here.

Study, Trial or Testing Result Summary
Members Only21 human studies · 11 improved
No study given here tested this drink, or its main ingredients, for keeping men hydrated. Potassium, the one ingredient with a stated dose, was studied in two small trials in men, and neither showed better hydration: a single potassium drink did not change blood vessel function or blood pressure and did not measure hydration [1], and a lower potassium diet during heavy exercise raised the liquid part of the blood [2]. The vitamins are hidden in a blend at unknown amounts. Vitamin A and vitamin B3 improved skin moisture only as creams or serums put on the skin, mostly in women, not as a drink [3][4][5]. Vitamin C did not improve skin moisture more than placebo [6][7]. A four week trial of a similar vitamin hydration drink in 40 men and women found it safe and well tolerated but did not measure hydration [8]. Calcium, vitamin B6, vitamin B12 and pantothenic acid have no hydration studies [9][10][11]. Iron and phosphorus have no human studies here. Animal and cell studies are never counted.

Review Totals and Summary
Members Only144,531 reviews · 93% positive
Liquid I.V. Lemon Lime powder is well liked overall, with about 136,237 ratings across the stores and most reviewers giving 4 or 5 stars. Buyers praise the flavor and the convenience of the packets. The few criticisms concern sodium and ingredients. **What buyers say it did for them:** Most describe it as helping them stay hydrated, especially in heat or during activity. One says it "keeps me from getting dehydrated," and another, in Arizona, calls the packets "a life saver" in extreme temperatures. Costco reviewers mention endurance training, hiking, and travel, and say it kept them hydrated for hours without a heavy or syrupy feel. Some report energy through the day, and one reviewer says it is essential for people with POTS or dysautonomia. A few report relief from leg cramps or migraines, but these are single personal accounts, and one reviewer admits the energy boost could be placebo. **Complaints:** Complaints are few. One 4-star reviewer says it "needs half the sodium," worrying that people double up without reading the warning label. A 1-star reviewer had not opened the box and returned nothing, but was put off by online research about the ingredients. Another wishes the packaging were biodegradable. The Sam's Club and Liquid I.V. website summaries show no complaints in the visible written reviews, though the website's histogram shows 37 ratings of 1 or 2 stars with no text. **Taste and form:** Flavor is the strongest theme. Reviewers call it "Terrific flavor" and say it is refreshing without being overly sweet, with no weird aftertaste. One says it is "like drinking lemonade," and a Costco reviewer compares it to old-school Gatorade. One reviewer likes the saltiness and the small amount of real sugar. Another says you can add more water if the taste is too strong, and a Costco reviewer found one packet in 32 ounces less concentrated and more palatable than the label's 16 ounces. The single-serve packets are described as easy to toss in a bag or purse and handy on planes. Reviewers also like that it has no caffeine, though one wishes a caffeinated version existed. **Value for money:** Opinions on value are positive but thin. One reviewer calls the price "very reasonable" and "great value." Sam's Club reviewers say a monthly membership means they never run out and saves a few dollars per packet. A website reviewer likes the bigger pack size for creating less waste. One Costco reviewer notes FSA eligibility made checkout easier. **Who it suits and who it didn't:** It seems to suit active people, such as runners, hikers, cyclists, and Ironman athletes. It also suits people in hot climates, travelers, people who dislike plain water, and those with physically demanding jobs or high hydration needs, including a breastfeeding reviewer. Households that want a no-caffeine flavor also like it. It suited least the reviewer concerned about sodium and ingredients, and anyone who wants a lower-sodium or biodegradable option. Reviews of other forms of the product, such as gummies and capsules, were left out; this summary covers the powder only.
Biohacker Summary
Members Only10 of 10 recommend it
Vitamin C is the main ingredient here, and most of the panel speaks well of it: Ben Greenfield, Siim Land, Dave Asprey, Dr. Mark Hyman and Dr. Rhonda Patrick recommend it, and Thomas DeLauer and Andrew Huberman use it. The main reasons are collagen and joint support, skin health, immune support and help during detox. Siim Land and Thomas DeLauer pair it with collagen, DeLauer taking both about an hour before a workout, and Ben Greenfield mentioned doses of 500 mg to 1 g while noting that the best dose is unsettled and that high doses might blunt the benefits of exercise. Potassium is the other lead ingredient: Dr. Eric Berg, Dr. Rhonda Patrick and Peter Attia recommend getting enough, Thomas DeLauer and Andrew Huberman use it in electrolyte drinks for workouts and hydration, and Attia favors food sources such as bananas and potatoes over supplements. Iron is a smaller ingredient in this product, and one panelist said he stopped taking it after years of no improvement before later getting his levels back to healthy.

RAL Summary
Members OnlyTier 4 for Hydration Men
The study support counted toward tier 3 comes only from vitamin A and vitamin B3 creams applied to the skin for skin moisture, which are a different form and goal and trace ingredients, while the main ingredient potassium showed no effect, so the evidence is thin. So it is graded Tier 4, lower than the rules alone gave.
- Emerging: not enough evidence to rank higher yet.
- Vitamin A: amount hidden in a blend
- Niacin: amount hidden in a blend
Where the evidence disagrees: 8 of the 21 human studies found no effect.

Combine with: For hydration purposes, pair this product with plain water and potassium-rich whole foods such as bananas, leafy greens and avocados, and use it mainly around heavy sweating, illness or endurance exercise rather than daily if blood pressure is a concern. For actual blood pressure support, consider supplements with clinical backing such as magnesium (glycinate or citrate), CoQ10, omega-3 fish oil, aged garlic extract, beetroot or nitrate-based formulas, and hibiscus extract. People with hypertension, kidney disease or those taking meds (meds, ARBs, potassium-sparing meds) should consult a physician before using electrolyte supplements, because sodium and potassium can interact with these treatments.
Possible side effects: No major side effects reported.
