Short answer: both deliver the same hydrolysed marine collagen with vitamin C for daily skin support — the difference is sweetening. Collagen Glow Berries has the classic berry taste many people love, while Berries Zero gives you the same collagen with no added sugar, for anyone watching their sugar intake or blood sugar.

What they share

Both are built around the same core: hydrolysed marine collagen peptides plus vitamin C (which your body uses to build collagen), taken as a daily berry drink. The collagen dose and the skin-support rationale are the same, so you're not trading away effectiveness either way.

The real difference: sugar

The original Collagen Glow Berries has a touch of sweetness for that classic taste. Collagen Glow Berries Zero delivers the same collagen with no added sugar — handy if you're cutting sugar, managing blood-sugar steadiness, or simply prefer a lighter taste.

How to choose

Pick Original if you love the fuller berry flavour and aren't fussed about a small amount of sugar. Pick Zero if you're sugar-conscious, watching blood sugar, or want to take it later in the day without the sweetness. Either way, consistency over 8–12 weeks and daily SPF matter most for results.
