sodium
the main electrolyte lost in sweat. water follows sodium, which is how your body absorbs and holds on to the fluid you drink. it also carries the electrical signals behind nerve and muscle function.
cellular hydration complex™
daily electrolyte & trace mineral liquid concentrate.
the first of its kind: a single-serve liquid concentrate. no powder, no frother, no mess.

formulated for people
who sweat the details.
built from two rigorously calibrated systems. explore them below.
electrolyte layer · per sachet
potassium
sodium's counterbalance inside the cell. it keeps fluid properly distributed and contributes to normal muscle and nerve function.
magnesium
a cofactor in more than 300 enzymatic reactions, including the ones that turn food into usable energy. we use magnesium citrate, a soluble form.
calcium
more than a bone mineral: a cellular messenger behind muscle contraction and nerve signalling. we use calcium lactate gluconate, a soluble form.
chloride
sodium's partner charge. it maintains fluid balance and contributes to normal digestion as part of stomach acid.
functional layer · per sachet
trace minerals
nine minerals your body needs in small amounts that do outsized work, from thyroid function to antioxidant enzymes. every dose is listed below.
hyaluronic acid
a molecule that attracts and holds water in skin and connective tissue. we chose a low-molecular-weight form made for drinking.
glycine
the smallest amino acid, and every third one in collagen's structure. it is also a building block of glutathione.
taurine
an osmolyte your cells use to regulate their own water balance. concentrated in muscle and nerve tissue.
water
the delivery medium. everything arrives already dissolved, so it disperses instantly in still or sparkling water. no powder, no frother, no mess.
(original) flavor system
allulose
a rare sugar found naturally in figs and raisins. a small amount rounds out the flavour. it is not a sugar alcohol, stevia or monk fruit.
citric acid
the brightness in citrus. it lifts the flavour and balances the salinity of the minerals.
malic acid
the tartness of a green apple. it softens citric acid so the finish is round, not sharp.
pectin
a natural fibre from fruit that gives the drink a fuller, smoother mouthfeel.
yuzu
natural yuzu extract: the flavour of the fruit itself. bright, tart and floral.
lychee
natural lychee extract: the flavour of the fruit itself. soft, floral and fragrant.

why a liquid, not a powder.
it mixes in seconds
the minerals are already dissolved. squeeze the sachet into water and it disperses on its own, with no gritty layer at the bottom of the glass.
still or sparkling
powders fizz over in sparkling water. a liquid concentrate goes straight in, so soda water becomes a mineral drink.
one sachet, one day
each 15 mL sachet is a full serving. it fits in a pocket, a gym bag or a carry-on, and there is nothing to measure.
how to use.
one sachet a day. good moments for it: before a workout, on hot days, after a long flight, or alongside your morning coffee.

questions, answered.
whenever it fits your day. most people take one in the morning, around a workout, on a hot day or after a flight. one sachet is one serving. [confirm recommended daily use.]
yes. the concentrate is already liquid, so it goes into sparkling water without foaming over the way powders do.
yes. original, yuzu and lychee share the identical hydration system. only the flavour system changes.
a small amount of allulose, a rare sugar found naturally in figs and raisins. there is no stevia, monk fruit, sugar alcohol or artificial sweetener. [confirm whether original contains allulose.]
caspia is formulated for adults. if you are pregnant, breastfeeding, on a sodium-restricted diet or managing a kidney or heart condition, ask your doctor before using it.
[lab name] tests every batch for heavy metals, microbial safety and label accuracy. the certificate for your batch is at [link].
