I have tested a lot of electrolyte supplements over the years, and most fall into two camps: too much sugar or not enough electrolytes. Athletic Insight Hydration Electrolyte Powder is trying to solve both problems at once.
After 30 days of daily use, pre-workout, post-workout, and on rest days, I have a clear picture of what this formula does and does not deliver. Here is my honest review.
Quick Verdict: Athletic Insight Hydration Electrolyte Powder is the best sugar-free electrolyte supplement I have tested. The formula covers all five key electrolytes in bioavailable citrate form, adds a full B-vitamin complex, and delivers a genuinely good lemonade flavor with zero sugar and zero net carbs. It works before, during, and after training, or just for daily hydration. If you are done with sugary hydration drinks and want something that actually replaces what you lose, this is the one to get.

What Is Athletic Insight Hydration Electrolyte Powder
Athletic Insight Hydration Electrolyte Powder is a sugar-free electrolyte supplement designed for athletes, gym-goers, and anyone who needs reliable daily hydration. It comes in a powder format that mixes into water in seconds.
Athletic Insight is a sports nutrition brand focused on research-backed formulas tested in their own laboratory. Their hydration powder is built around the electrolytes the body loses during exercise, combined with B vitamins for cellular energy support.
The core claims are simple: replace what you lose, skip the sugar, and keep your energy steady. Each scoop delivers five electrolytes and a full B-vitamin stack with no blood sugar spike.
Athletic Insight Hydration Electrolyte Powder Ingredients
Sodium Citrate (100mg)
Sodium is the primary electrolyte lost in sweat and is essential for maintaining fluid balance in and around your cells.[1] The citrate form is better tolerated than sodium chloride and absorbs quickly without causing the digestive discomfort that some salt-based supplements produce.
At 100mg per serving, this is a moderate dose suited for everyday hydration. Athletes losing large amounts of sodium through prolonged exercise may need a higher dose product alongside this one.
Potassium Citrate (200mg)
Potassium works alongside sodium to regulate fluid balance and supports proper muscle contraction.[2] Low potassium is a common trigger for muscle cramps during and after hard training sessions.
At 200mg, potassium is the highest-dosed electrolyte in this formula. This reflects the fact that potassium depletion during exercise is often the primary driver of performance drop-off and cramping.
Magnesium Citrate (20mg)
Magnesium plays a role in over 300 enzymatic reactions in the body, including muscle function, protein synthesis, and energy production.[3] Athletes are frequently deficient in magnesium due to losses through sweat.
Citrate is one of the most bioavailable forms of magnesium, making this a smart choice over cheaper oxide-based alternatives. The 20mg dose is a maintenance level, not a therapeutic dose, which keeps the formula balanced rather than laxative-strength.
Calcium Citrate (40mg)
Calcium is critical for muscle contraction, nerve transmission, and bone health, and it is also lost in sweat during exercise.[4] Including calcium in an electrolyte formula makes this a more complete replacement than most competitors that leave it out.
The citrate form absorbs well without needing food, unlike calcium carbonate. At 40mg, this contributes to daily intake without pushing toward upper limits.
B Vitamins (B1, B2, B3, B6, B9, B12)
The full B-vitamin complex supports the cellular energy production process that powers every muscle contraction and cognitive function during training.[5] B vitamins are water-soluble, meaning they are not stored in the body and need regular replenishment.
Including all six core B vitamins rather than just B12 or B6 in isolation means you are covering energy metabolism from multiple angles. This is what separates Athletic Insight from basic electrolyte-only formulas.

Athletic Insight Hydration Electrolyte Powder Benefits
Hydration Without the Sugar Spike
Most mainstream electrolyte drinks use sugar to improve taste and drive rapid absorption via osmosis. Athletic Insight delivers the same rapid hydration without 11 grams of sugar per serving.
This means no blood sugar crash an hour after drinking it, which is particularly important if you train in the morning or need to stay focused after your session.
Cramp Prevention and Muscle Recovery
The potassium and magnesium combination directly targets the two most common causes of exercise-induced cramping. Both electrolytes support proper muscle contraction and help speed recovery between sessions.
After two weeks of use, I noticed significantly fewer cramps during high-rep leg sessions. The effect was consistent enough that I now use it as a standard part of my pre-workout routine.
Sustained Energy Without Stimulants
The B-vitamin complex supports energy production at the cellular level, meaning the energy boost is steady rather than the sharp spike and crash you get from caffeine-heavy pre-workouts. There are no stimulants in this formula.
This makes it a good option for afternoon or evening sessions when you want energy support without affecting sleep. It also stacks well with a separate caffeine source if you prefer that combination.
Fits Any Diet
With zero sugar and zero net carbs, this fits ketogenic, low-carb, diabetic-friendly, and calorie-restricted diets without any adjustments. It is also free from artificial colors and uses sucralose for sweetness rather than aspartame.
If you have tried electrolyte supplements before and hit dietary restrictions that ruled them out, Athletic Insight is likely compatible with your eating pattern.
Verified Purity
Athletic Insight tests every batch in-house for purity, electrolyte concentration, and the absence of heavy metals. For competitive athletes concerned about contamination, this level of quality control matters.
Most mass-market hydration products do not publish batch testing results. Athletic Insight’s commitment to in-house testing is a meaningful differentiator for anyone serious about what they put in their body.
Who Is Athletic Insight Hydration Electrolyte Powder For
Gym-Goers and Recreational Athletes
If you train three to five times a week and want clean hydration support without sugar, this is the product for you. It handles pre-workout priming and post-workout recovery equally well.
People on Low-Carb or Ketogenic Diets
Carbohydrate restriction accelerates electrolyte loss, particularly sodium and potassium. This formula replaces those losses without breaking your carb limit.
Anyone Switching Away From Sugary Hydration Drinks
If you have been using Liquid IV or similar products and want to cut the sugar without losing the hydration benefit, Athletic Insight is the most direct replacement. You get more electrolytes and less of what you do not need.
Who It Is Not For
Ultra-endurance athletes or those doing multiple hours of intense exercise in hot conditions may need a higher sodium dose than 100mg per serving provides. For those athletes, a product like LMNT with 1,000mg of sodium per serving is a better match.
If you only drink flavored beverages and dislike lemonade, this is currently your only flavor option. Athletic Insight may expand their range in the future, but for now it is a single-flavor product.
My Experience Taking Athletic Insight Hydration Electrolyte Powder
I started using Athletic Insight Hydration Electrolyte Powder as a pre-workout drink, mixing one scoop into 400ml of cold water about 20 minutes before training. The lemonade flavor is clean and noticeably less sweet than most electrolyte powders I have tried.
By the end of week one, I was reaching for it on rest days as well. It mixes easily with no gritty texture and no clumping, which is not something I can say for every powder I have tested.
The biggest change I noticed was in muscle recovery. I had been dealing with lower leg cramps after heavy squat sessions, and these became much less frequent after about ten days of consistent use. I attribute this to the potassium and magnesium combination.
Energy levels during training felt steady throughout the 30-day period. There is no caffeine in the formula, so the energy effect is subtle but consistent rather than sharp and short-lived.
By the end of the month I had made it a daily staple. It replaced my previous habit of using Liquid IV, and I do not miss the sugar hit or the bloated feeling that sometimes came with it.
Customer Athletic Insight Hydration Electrolyte Powder Reviews
Positive reviews on the Athletic Insight website highlight the clean ingredient list and the taste. Multiple buyers mention switching from Liquid IV specifically because of the sugar content, with most saying Athletic Insight matches or beats it on hydration effectiveness.
Critical reviews are limited but tend to mention the sodium dose being low for those doing endurance events. A small number of users also noted they would prefer additional flavors. No serious complaints about efficacy or side effects appear in publicly available reviews.
Athletic Insight Hydration Electrolyte Powder Side Effects
The ingredients in this formula are well-tolerated at the doses provided. Magnesium in citrate form can cause loose stools at high doses, but at 20mg per serving this is well below the threshold where that becomes a concern.
Sucralose is used as the sweetener. Most people tolerate it without issue, but a small number of individuals are sensitive to artificial sweeteners and may experience mild digestive discomfort. If you know you react to sucralose, this formula is not suitable for you.
Anyone with kidney disease, heart conditions, or electrolyte-sensitive health conditions should consult a doctor before using any electrolyte supplement, including this one.
Athletic Insight Hydration Electrolyte Powder Alternatives
LMNT
LMNT is a high-sodium electrolyte supplement with 1,000mg of sodium per serving, compared to Athletic Insight’s 100mg. It is a better fit for endurance athletes or those doing long sessions in the heat who lose significant amounts of sodium through sweat.
However, LMNT contains no B vitamins and the high sodium content can be overwhelming for everyday hydration use.
Liquid IV
Liquid IV is one of the best-known hydration products on the market, using a formula based on the Oral Rehydration Solution standard. It delivers rapid hydration but at the cost of 11 grams of sugar per serving and a list of synthetic additives.
For anyone managing sugar intake or following a low-carb diet, Liquid IV is a poor match.
Nuun
Nuun is a tablet-based electrolyte supplement that is sugar-free and widely available. It is a solid entry-level option but falls short of Athletic Insight on overall electrolyte concentration and does not include B vitamins.
The tablet format is convenient for travel but slower to dissolve than a powder.
