Why fibre and
electrolytes
Fibre and hydration aren't separate problems. Your gut needs both to function well, and most supplements only give you one.
Fibre needs water to work
Soluble fibre absorbs water as it moves through your gut. Without adequate hydration and electrolytes, fibre can actually worsen constipation. Sol.ve delivers both together.
Electrolytes support gut motility
The smooth muscle contractions that move food through your bowel are regulated by electrolytes, particularly sodium, potassium and magnesium. Low levels can leave your gut feeling sluggish.
Magnesium for muscle function
Magnesium is necessary for normal muscle function, including the muscles involved in digestion, which can be directly affected by hormonal changes after 40.
One drink, solved
Instead of a separate fibre supplement, a separate magnesium supplement and an electrolyte drink, Sol.ve combines four minerals with clinically studied PHGG fibre in one serve.
The hero ingredient
PHGG, the fibre
your gut can
actually tolerate.
Sol.ve is built around Partially Hydrolysed Guar Gum, a soluble prebiotic fibre made from guar beans. It is designed to support fibre intake without the thick, gluey feel of traditional fibres. A smarter daily fibre for real bodies and real routines.
PHGG has been widely studied for digestive health, regularity, gut balance, satiety and metabolic support, making it one of the most considered fibres for daily use.
Unlike traditional fibres that can become heavy or gluey, PHGG has a smooth, low-viscosity texture that makes it easier to take consistently.
The best fibre is the one you will actually keep taking. PHGG was chosen because it is gentle, practical and easy to make part of your everyday routine.

What it does
Six reasons your gut
needs Sol.ve
Supports regular bowel movements
Dietary fibre contributes to regular laxation — helping you stay comfortable and consistent without harsh stimulants.
Feeds your good gut bacteria
PHGG acts as a prebiotic — nourishing beneficial bacteria linked to a balanced gut microbiome and better overall digestive health.
Supports hydration for digestion
Added sodium and potassium support electrolyte balance — because good digestion depends on good hydration at the cellular level.
Supports bones, teeth and muscles
25% of your daily magnesium RDI and 10% calcium RDI — both necessary for normal nerve, muscle, and bone function.
Contributes to energy metabolism
Magnesium contributes to normal energy metabolism and a reduction in tiredness and fatigue — something every adult over 40 notices.
Completely dissolves — no texture
No grit. No gel. No paste. Just 2.5 teaspoons into 200–400ml of water. Disappears completely — you won't know it's there until you feel it.
A GP who experienced
the problem herself
"After having my second baby and heading into my late 30s, my own gut health took a hit. I knew exactly what I needed — but I couldn't find a fibre supplement I'd actually stick to. Everything was gritty, gluey, or just unpleasant. So I formulated one I'd take myself."
