Calcium (Ca)
Reptiles, amphibians, and other pets require calcium for strong and healthy bones, including teeth as well as for other physiological functions like muscle functioning, nerve impulse transmission, heartbeat regulation, metabolism, among others.
A deficiency in this mineral will result in hypocalcemia (low blood calcium level) and other disease and conditions, including metabolic bone diseases. Hypocalcemia will cause muscle twitches, lethargy, and neurological symptoms in severe cases.
Phosphorus and oxalic acid in diets, vitamin D, the bioavailable amount in food, and so on will influence how much calcium these pets absorb. Phosphorus and oxalic acid bind with this mineral while in the stomach hence reduce bioavailability.
Vitamin D3 or cholecalciferol
As you have seen, calcium is quite vital for your pets. On the other hand, vitamin D3 (cholecalciferol) helps in its absorption. Besides dietary sources, any pet that requires UV light to make cholecalciferol should get cholecalciferol supplements too.
Best calcium with or without vitamin D3 supplements for reptiles
We have seen the essence of supplementation with this mineral and cholecalciferol. If you need them, most of these supplements are available liquid, spray, or powdered forms.
Besides, some veterinarians may recommend liquid calcium gluconate absorbed quickly or bone meal as it is easy to know how much you have added.
Finally, you need to decide if you want those with or those without vitamin D3. You don’t have to buy those with it if your reptile or amphibian doesn’t require UV light or has enough UV light mainly from the sun.
The best calcium supplements (powders, liquids, and sprays) without or without vitamin D3 include the following:
