Oxbow Natural Science Vitamin C Support is a tablet supplement designed for guinea pigs and other small animals that cannot synthesise their own vitamin C. Each tablet combines stabilised vitamin C with high-fibre Timothy hay, addressing both the deficiency risk common in guinea pigs and their need for consistent dietary fibre in a single daily supplement.

Guinea pigs rely entirely on dietary sources for vitamin C — deficiency leads to lethargy, rough coat, and joint deterioration. Oxbow uses a stabilised form that resists breakdown over the tablet's shelf life, ensuring each dose delivers what's on the label. High-fibre Timothy hay adds digestive support alongside the vitamin. The formulation was developed with input from vets and small animal nutritionists and comes in a 60-tablet count.

A reliable daily supplement for guinea pig owners who want a consistent vitamin C source beyond fresh vegetables alone. Particularly practical during illness, stress, or recovery, when appetite drops and dietary intake becomes less predictable.
