Bio PetActive Betisol is a liquid vitamin B complex for cage birds, added to drinking water. It's a targeted supplement rather than a general multivitamin — built for moulting, stress and breeding, the times a bird's B-vitamin demand climbs.

Why B vitamins, and why at moulting

The B-complex vitamins sit at the centre of how a bird turns food into energy and keeps its nervous system running. They aren't stored in the body for long, so the bird needs a steady supply — and when demand spikes, a seed diet can fall behind.

Moulting is one of those spikes: regrowing a full set of feathers is metabolically expensive, and it leans heavily on the B group. Breeding, showing, and general stress do the same. Betisol is built for exactly these windows — a concentrated top-up of the vitamins most likely to run short when the bird is working hardest.

• ✓Eases the moult. Supports feather regrowth through the most demanding part of the year.
• ✓Supports the nervous system. B vitamins are central to nerve function and steady energy.
• ✓Helps through stress. A buffer during transport, showing, or seasonal change.
• ✓Supports breeding. Aimed at breeding performance and the healthy development of young birds.
• ✓Can help a poor appetite. B vitamins are tied to appetite, and the maker notes its use where a bird is eating poorly.

Betisol or a full multivitamin?

Think of Betisol as the specialist. A general multivitamin covers the everyday vitamin gaps of a seed diet across the year; Betisol concentrates on the B group for the specific stretches — moulting, breeding, stress — when that group is under the most pressure. Many keepers run a general multivitamin as routine and reach for a B-complex like this during the moult. The two complement each other rather than compete.
