Food supplements:
If you are giving your monkeys a balanced and versatile diet, then very few supplements will be needed. Calcium Deficiency is a possibility, and adding a little bit of extra calcium into the diet. Just remember that the absorption of Calcium into the body relies almost entirely on the presence of Vitamin D3. This is why it is essential that your Monkey receives direct sunlight on a daily basis. Vitamin D3 is produced from direct sun to skin exposure (not through glass)Be careful with adding extra vitamins to your Monkeys diet, as this can be a danger to their livers in too large amounts. If you maintain a balanced diet of fruits and vegetables, your marmoset should receive all the nutrition it needs. Natural vitamins obtained from a correct diet are more beneficial than any supplement.
a small amount of Energade - on extremely warm days - can help to put all the electrolytes back into your monkey's system. It is also very good to prevent dehydration, and so in cases where your Monkey is suffering from diarrhea, it is very good.
