The electrolyte market has a sweetener problem. Most formulas use stevia or monkfruit because they're calorie-free and technically "natural" — but the aftertaste is real, and for a growing number of people the blood sugar signaling effects of sweeteners (artificial or not) are something worth avoiding. Conventional sports drinks use sugar. The clean alternatives use stevia. There hasn't been a meaningful third option.

Subluna built one. Mermaid Water uses glycine — an amino acid — as its natural sweetener, and it works: glycine is inherently sweet, completely non-synthetic, and happens to be one of the most important amino acids in the body for collagen production, gut lining integrity, and regulation of the nervous system toward calm and sleep. The sweetness is a side effect of a functional ingredient, not the other way around.

The electrolyte base is organic coconut water powder (potassium, sodium, magnesium, antioxidants) and sea salt (sodium, chloride, trace minerals) — the minerals your body actually needs for fluid regulation, muscle function, and cellular hydration. Organic cucumber fruit adds silica and hydration with a cooling quality that makes this taste like the best version of spa water you've had.

Then the botanical depth: Organic sea moss — one of the most mineral-dense plants on earth, containing 92 of the 102 minerals the human body uses, including iodine, iron, calcium, magnesium, and potassium. Organic nopal cactus (prickly pear) brings betalains — pigment antioxidants specific to cactus that have anti-inflammatory and hydrating properties and are only available in a handful of foods. Organic spirulina (blue and green) adds chlorophyll, protein, B vitamins, and iron for cellular energy. Organic sea buckthorn contributes omega-7, vitamin C, and the same coastal antioxidant profile that makes it valuable in topical skincare. Horsetail — the most silica-rich plant source — supports collagen integrity, hair, skin, and connective tissue. Organic peppermint cools and calms.

No caffeine. Third-party tested. Safe during pregnancy and breastfeeding per Subluna's own research into each ingredient.
