Quick answer: Both are clean-label electrolyte drinks aimed at wellness-conscious buyers. Just Ingredients (founded by wellness influencer Karalynne Call) focuses on minimal-ingredient transparency and organic sourcing. Instant Hydration provides higher electrolyte density and a fuller vitamin complex with clean sweeteners. For ingredient purists, Just Ingredients’ shorter label is appealing. For effective daily hydration, Instant Hydration has the better formula.

What Is Just Ingredients?
Just Ingredients was founded by Karalynne Call, a popular wellness influencer known for her Instagram account and podcast focusing on clean living, motherhood, and food transparency. The product’s philosophy:
- Fewer ingredients, all recognizable
- Organic when possible
- No seed oils, no gums, no synthetic colors
- Transparent sourcing
The brand extends beyond hydration to include protein powder, greens powders, and other wellness staples. The hydration product specifically markets itself as the cleanest electrolyte drink you can buy — though that claim is competitive with Cure Hydration and Instant Hydration.
What Is Instant Hydration?
Full detail in our Instant Hydration review. For this comparison, the key facts:
- 500mg sodium, 470mg potassium, 50mg magnesium, 100mg calcium
- 0g added sugar (stevia + monk fruit)
- Full B-complex + 150mg Vitamin C
- 9 flavors
- Published third-party Certificates of Analysis
Ingredient Transparency Comparison
Just Ingredients’ approach
The hydration product lists approximately 8 ingredients on the label. You’ll recognize all of them from a kitchen. Example:
- Sea salt
- Coconut water powder
- Lemon juice powder
- Organic cane sugar
- Stevia leaf extract
- Real fruit powder
- Potassium citrate
- Magnesium citrate
This is genuinely short and genuinely clean. If you’ve ever been frustrated reading 40-ingredient wellness product labels, Just Ingredients solves that.
Instant Hydration’s approach
Instant Hydration lists approximately 15 ingredients — longer than Just Ingredients, shorter than most mass-market competitors. Notable inclusions:
- B-vitamin complex (cyanocobalamin, pyridoxine, niacin, pantothenic acid)
- Vitamin C (ascorbic acid)
- Calcium lactate
- Monk fruit extract alongside stevia
- Natural flavors
The “longer” list is almost entirely vitamins. If you want the added vitamin complex, you accept the longer label. If you don’t care about the vitamins, Just Ingredients is shorter and cleaner.
Who wins on ingredient purism?
Just Ingredients wins on pure ingredient count and label readability. Instant Hydration is close — neither contains artificial colors, artificial flavors, or synthetic sweeteners.
Electrolyte Content
This is where the comparison gets decisive.
Sodium
- Instant Hydration: 500mg
- Just Ingredients: 250mg
Instant Hydration has double the sodium. For meaningful athletic or recovery hydration, this matters.
Potassium
- Instant Hydration: 470mg
- Just Ingredients: 250mg
Nearly double. Potassium is the most frequently under-consumed electrolyte.
Magnesium
Both: 50mg — tie.
Electrolyte verdict
Instant Hydration wins substantially. Just Ingredients’ sodium and potassium levels are closer to “mineral-fortified water” than to a proper electrolyte drink. For users who want the full electrolyte replacement benefit, Instant Hydration delivers significantly more per serving.
Sweetener Analysis
- Instant Hydration: 0g sugar, sweetened with organic stevia + organic monk fruit
- Just Ingredients: 2g sugar (organic cane sugar) + organic stevia
Just Ingredients’ 2g of cane sugar is minor — it’s there primarily for flavor, not for glucose cotransport activation. If you’re strictly zero-sugar (keto, diabetes), Instant Hydration wins. Most buyers won’t care about 2g.
Third-Party Testing + Certifications
- Instant Hydration: publishes batch Certificates of Analysis publicly, manufactured in FDA-registered GMP-certified facility
- Just Ingredients: less transparent about batch testing. Brand emphasizes ingredient sourcing rather than batch-level testing.
For buyers who want documented heavy-metal and purity testing, Instant Hydration has better transparency infrastructure. Just Ingredients relies more on trust-the-founder brand equity.
Price
- Instant Hydration: $1.83/serving subscribed
- Just Ingredients: $1.70/serving subscribed
Just Ingredients is marginally cheaper. The price gap is smaller than the value gap — you’re getting meaningfully more electrolyte density and vitamin content from Instant Hydration for 8% more.
Taste
Our blind panel:
- Top Instant Hydration (Watermelon Mint): 9.2/10
- Top Just Ingredients (Watermelon): 7.9/10
Just Ingredients’ flavors are reminiscent of Cure Hydration — subtler, more natural, less engineered. Fans of clean, minimal flavors prefer Just Ingredients. Most of our panel preferred Instant Hydration’s more vivid flavor profile.
Our Pick
For most buyers: Instant Hydration.
Higher electrolyte content, better vitamin complex, better third-party testing transparency, better flavors, marginal price premium.
For ingredient minimalists and Karalynne Call fans: Just Ingredients is a legitimate clean-label pick. The shorter ingredient list has real appeal for a specific buyer, and the brand ethos lines up well for people who already follow Karalynne’s other content.
If you’re choosing between the two on product alone, Instant Hydration is the better product. If you’re factoring in brand affinity, Just Ingredients has passionate fans for a reason.

Instant Hydration, decisively. Double the sodium (500mg vs 250mg) and nearly double the potassium (470mg vs 250mg).
