Skratch Labs is the taste pick of this lineup, and endurance athletes have long known it. Sweetened with real fruit and a small amount of cane sugar rather than stevia or artificial sweeteners, it's light, clean and genuinely drinkable hour after hour — the mix you'll actually finish on a long ride, run or hike. The small dose of cane sugar is functional carbohydrate to fuel working muscles, not a marketing flaw, and the ingredient list is exactly the kind endurance athletes favor over heavily-flavored mixes. The reasons it sits at #7 are dose and sugar, and we're blunt about both. It isn't zero-sugar or keto — that ~4 g of cane sugar rules it out for fasting and low-carb goals — and it's tuned for palatable light fueling rather than maximal electrolyte replacement. Sodium is a respectable ~380 mg, but potassium is notably low at ~39 mg, so the mineral spread is thin. Skratch is the best-tasting training-day mix here and a trusted endurance brand; it just isn't built to be your high-salt, full-spectrum, or zero-sugar electrolyte.

Read the complete Electrolyte Powder guide →Mid-pack and uneven. Sodium is a reasonable ~380 mg per serving, but the total electrolyte load is held back by very low potassium (~39 mg) and only small magnesium and calcium. It's a serviceable training-day dose, not a high-content salt mix — well short of LMNT (~1000 mg) and Redmond (~810 mg) on the decisive sodium measure, and thin on the supporting electrolytes.
Clean ingredients, but not zero sugar. Skratch uses real fruit and a small ~4 g of cane sugar with no artificial sweeteners, colors or flavors — genuinely clean and light. It scores well for ingredient honesty but is marked down for everyday, keto and fasting use because the sugar, while functional fuel during exercise, disqualifies it for sugar-free goals.
The weakest axis. There's a token magnesium (~38 mg) and calcium (~38 mg), but potassium is only ~39 mg — among the lowest in the lineup. This is a sodium-led fueling formula, not a complete mineral spread, so a buyer wanting a genuine potassium-and-magnesium load should look to Redmond Re-Lyte (#3) or Trace Minerals Power Pak (#9) instead.
Solid. The 20-serving resealable bag works out to roughly $1.00 per serving — mid-range here and fair for a trusted endurance brand with a clean, real-food formula and functional carbs. Not the cheapest zero-sugar option (Key Nutrients is ~$0.85), but reasonable value for its intended training use.
Best-in-class — the whole reason to buy it. The light real-fruit Lemon & Lime flavor is widely praised as the most drinkable in the category over a long effort, with no artificial sweetener aftertaste, and it mixes cleanly into 12–16 oz of water. For daily training compliance, nothing here is more pleasant to actually finish.
“Real-fruit flavor with no artificial sweeteners, colors or flavors.”
Consistent with the documented label — Skratch is sweetened with real fruit and cane sugar and contains no artificial sweeteners, colors or flavors. This is the clean-ingredient claim behind its category-leading taste reputation, and it's accurate as stated.
“Light cane sugar provides fuel for working muscles during exercise.”
Mechanistically sound. The ~4 g of glucose-plus-fructose cane sugar supplies usable carbohydrate during exercise, which is the intended function of a sport-drink mix. The claim is accurate provided buyers understand it's a deliberate feature for training, not a sugar-free everyday hydration product.
“Effective hydration for athletes.”
True for its niche, with a caveat. The ~380 mg sodium plus light carbs supports fluid uptake during exercise, but the very low ~39 mg potassium and thin mineral spread mean it's tuned for palatable light fueling rather than maximal electrolyte replacement. Effective for training-day hydration; not a high-content electrolyte replacer for heavy losses.
Skratch's reputation rests on palatability over a long effort. Real fruit and a small amount of cane sugar give it a light, clean flavor with no artificial aftertaste, which is exactly why endurance athletes reach for it on rides and runs where a heavily-flavored mix becomes hard to stomach. Taste is only 10% of our methodology, but it's the difference between a mix you finish mid-effort and one you abandon — and on that axis Skratch leads the lineup.
The ~4 g of real cane sugar is a deliberate design choice: glucose and fructose to fuel working muscles during exercise. For a training drink that's a feature, not a defect. But it does disqualify Skratch for keto, fasting, or anyone cutting sugar, which is why it's marked down on the clean-formula axis for everyday use. Read it for what it is — a sport-fueling mix, not a sugar-free daily electrolyte.
The clearest weakness is the mineral profile. Sodium is reasonable at ~380 mg, but potassium sits at only ~39 mg — among the lowest here — with just token magnesium and calcium. Skratch is sodium-led and fuel-focused, not a full-spectrum electrolyte. A buyer who wants a genuine potassium-and-magnesium load alongside the sodium is better served by Redmond Re-Lyte (#3) or Trace Minerals Power Pak (#9).
Skratch is a long-trusted name in endurance sport, and the 20-serving resealable bag at roughly $1.00 a serving is fair for a clean, real-food formula with functional carbs. It isn't the cheapest zero-sugar option in the lineup, but you're paying for taste, reliability and light fueling. For its intended training use, the combination of brand trust, clean ingredients and palatability justifies the mid-range price.
Skratch Labs is the mix you'll actually enjoy drinking over a long ride or run: light real-fruit flavor, a small dose of cane sugar for fuel, and a clean ingredient list with no artificial sweeteners or colors. On taste and tolerability during exercise — the thing that decides whether you keep sipping mid-effort — it's the best in this lineup, and it comes from a trusted endurance brand at fair value. It lands at #7 because it's a sport-fueling mix first and an electrolyte replacer second. The ~4 g of cane sugar disqualifies it for keto and fasting, and the mineral profile is sodium-led with notably low potassium and only token magnesium. Buy Skratch for endurance training days where taste and gentle carbs are the goal. For zero-sugar salt replacement reach for LMNT (#1) or Redmond Re-Lyte (#3), for a full mineral-and-magnesium load Trace Minerals Power Pak (#9), and for the cheapest zero-sugar everyday mix Key Nutrients (#8).
