Women aren't small men.
So why drink a formula made for one?

Most electrolyte drinks were built on research done almost entirely on men. Sora starts from female physiology. Here's the science that proves why it matters.

Built for Her DNA

Not a generic formula. Every ingredient in Sora was chosen for a specific reason rooted in women's biology. Premium forms, purposeful doses, zero filler. You'll see exactly why below.

Body water & baseline hydration
Women
Hormone-driven hydration
Men
Volume-driven hydration
~49% water
Women's body weight is roughly 49% water due to naturally higher body fat, which holds far less water than muscle. Women have a smaller fluid reserve — dehydration hits harder and faster.
~58% water
Men's higher muscle mass means their bodies are about 58% water. They start every workout with a larger fluid buffer and more tolerance for fluid loss before performance drops.
Sora's formula
Coconut Water Powder + a calibrated sodium-potassium ratio keeps plasma volume up and fluid where it belongs. Unlike drinks that overload sodium and leave you bloated and sloshy, Sora uses just enough to do the job — so you feel hydrated, not heavy.

Body water composition
Men carry roughly 9 more percentage points of body water than women — equivalent to almost 7 litres of additional fluid reserve at rest.

Sweat rate & sodium loss
Women
Hormone-driven hydration
Men
Volume-driven hydration
Narrower tolerance
Women sweat less per hour but tolerate fluid loss in a much narrower range. Progesterone also promotes active sodium loss through the kidneys during the luteal phase — increasing depletion risk even at rest.
Higher volume loss
Men typically lose more sodium per session — up to 3g in a single intense workout. Larger body size and muscle mass generate more heat, demanding higher sweat rates to cool down.
Sora's formula
Without sodium your body can't hold onto the fluid you drink. But the answer isn't more sodium — it's the right amount. Sora replaces what's lost through sweat and hormonal excretion without tipping into the excess that causes bloating. That's a formula designed for women, not just a smaller serving of a men's drink.

Bone density & injury risk
Women
Hormone-driven hydration
Men
Volume-driven hydration
2–4× higher fracture risk
Women have smaller, thinner bones and rely on estrogen to maintain bone density. When estrogen fluctuates, bone loss accelerates. Female athletes are 2–4× more likely to suffer stress fractures, and ACL tears occur up to 8× more often in women than men.
Greater bone mass
Testosterone supports denser cortical bone. Stress fracture rates in identical training conditions run 0.9–7.9% in men versus 3.4–21% in women. Men don't face estrogen-driven bone loss cycles.
Sora's formula
Sora uses Calcium Citrate Malate (CCM) — one of the most bioavailable forms of calcium, shown to maintain bone mass and reduce fracture risk. Paired with Vitamin D at 130% DV — the transport mechanism your body needs to actually absorb that calcium. No Vitamin D, no benefit. Most electrolyte drinks include neither.

Stress fracture rates under identical training loads
In military recruit studies, women experience stress fractures at significantly higher rates than men performing the same training — up to 21% vs. 7.9% at the high end.

"Train just as hard on day one of your period as any other day of the month."

Hormonal influence on electrolytes
Women
Hormone-driven hydration
Men
Volume-driven hydration
Cycle-driven depletion
Estrogen alters fluid retention thresholds. Progesterone drives sodium loss through the kidneys. Magnesium depletes rapidly in the luteal phase — directly impacting mood, sleep, and cramping.
Stable hormonal baseline
Testosterone supports consistent muscle mass and steady electrolyte demand. No monthly hormonal swings mean men's hydration and recovery needs are largely predictable day to day.
Sora's formula
Magnesium Bisglycinate — the most absorbable, stomach-friendly form — drives over 300 enzymatic reactions including energy, mood, and sleep regulation. The full B-Vitamin Blend supports the cellular pathways that hormonal fluctuations disrupt. Not just replacing what's lost — supporting the systems that keep you feeling even all month.

Iron, cycles & training through your period
Women
Hormone-driven hydration
Men
Volume-driven hydration
Monthly iron loss
Menstruation causes regular blood loss, making iron deficiency one of the most common issues in active women. Low iron causes fatigue, cramps, reduced oxygen delivery, and brain fog — compounded when you're also losing iron through sweat during training.
No monthly loss cycle
Men don't experience monthly iron depletion through menstruation. Their iron needs are relatively stable and easily met through diet, with no recurring hormonal cycle creating compounding loss over weeks of training.
Sora's formula
Ferrous Bisglycinate (4mg / 20% DV) — a highly absorbable, gentle form of iron — supports red blood cell production, oxygen delivery, and helps combat the fatigue and cramping that comes with your cycle. Vitamin C (100mg) is included specifically to enhance iron absorption. The goal: train just as hard on day one of your period as any other day.

What's actually in Sora vs. a typical electrolyte drink
Most electrolyte drinks skip the ingredients women actually need. Sora includes the full picture — hover each bar to see the detail.
Sora — fully included Typical drink — low dose Typical drink — not included
Sora includes Iron, Magnesium, Calcium, Vitamin D, Tart Cherry, MSM, B-Vitamins. Typical drink has only some electrolytes.

Muscle recovery — women take longer
Women
Hormone-driven hydration
Men
Volume-driven hydration
Longer recovery window
Women experience greater exercise-induced muscle damage relative to their muscle mass, and hormonal fluctuations in the luteal phase increase inflammatory markers and extend recovery time — making overuse injury a bigger compounding risk.
Faster baseline recovery
Testosterone supports faster muscle protein synthesis and recovery. Men's higher muscle mass distributes eccentric load more broadly, reducing peak soreness. Recovery needs are driven by intensity, not hormonal inflammatory cycles.
Sora's formula
Organic Tart Cherry inhibits the same COX-1 and COX-2 inflammatory enzymes as ibuprofen — naturally. Studies on female athletes show it reduces inflammation markers, shortens DOMS, and speeds strength recovery. MSM reduces oxidative stress in muscles and joints, supports collagen, and protects hair health — strengthening keratin against the constant stress of sweat, heat, and frequent washing. Recovery isn't just about your muscles.

Cognitive & mood impact of dehydration
Women
Hormone-driven hydration
Men
Volume-driven hydration
Mood & focus hit first
Research shows women experience greater mood disturbance and slower reaction time under mild dehydration — before physical performance is even affected. Sodium drops trigger measurable mood shifts in women that don't appear in men under the same conditions.
Physical output drops first
For men, dehydration shows up as reduced cardiac output and declining physical performance first. The emotional and cognitive sensitivity women show to electrolyte drops is significantly less pronounced in male physiology.
Sora's formula
Palatinose (Isomaltulose) delivers slow, steady glucose — real lasting energy without the spike and crash of high-sugar drinks. Combined with the B-Vitamin Blend for cellular energy and iron for oxygen delivery, Sora supports how you feel and function all day — not just during your workout.

The bottom line. Most electrolyte drinks were built for men and repackaged with a new label. Sora started from scratch — formulated around how women lose electrolytes, sustain injuries, recover, and train through their cycles. Every ingredient has a reason to be here.
