The vegetable gap is real, boring, and worth closing
Singapore adults average under two servings a day. A greens tablet is not a replacement — it is a floor.
The gap is real and boring
National nutrition surveys here put average adult vegetable intake at under two servings a day against a recommendation of at least two servings of vegetables plus two of fruit. The shortfall is not exotic — it is fibre, folate, potassium, magnesium and carotenoids.
No tablet closes that gap. A greens tablet raises the floor on a bad week, which is a smaller claim and a true one.
What a greens tablet can and cannot do
It can supply concentrated chlorophyll, phycocyanin, carotenoids and a modest amount of B vitamins in a compressed form. It cannot supply the volume, the water, the potassium load or the chewing that a plate of vegetables does.
Treat it as insurance against the days you eat badly, not as a substitute for the days you eat well.
Spirulina and chlorella are not interchangeable
Spirulina is a cyanobacterium with no cellulose cell wall, high in phycocyanin and readily digestible. Chlorella is a true green alga with a tough cell wall that has to be mechanically cracked to be bioavailable at all — look for "cracked cell wall" on the label or assume it is not.
They complement each other, which is why serious formulas carry both rather than one at a larger number.
Where it fits
This is the least interesting product in most ranges and the one most people would benefit from first. If you take nothing at all and eat like most people in a city, start here rather than with the specialist formula for the problem you find most annoying.
Then add one targeted formula. Not three.
