SOLUVITE D is highly recommended for indoor birds!
Birds need to have a great exposure of sunlight for its vitamin. They need natural sunlight for Vitamin D production, hormone balance, and organ, skin and feather health. However in Singapore, not everyone are able to sun their birds often due to the housing we live in. Especially during rainy season too. Hence, Soluvite D has a role in the absorption for calcium, which are essential for normal growth of healthy bones in young birds and for normal eggshell formation in breeding hens. Soluvite D also contained all 12 essential vitamins required for a balanced diet in birds along with increased levels of vitamin D3 to support birds with insufficient access to natural sunlight.
