My turtle seemed like he was having eye problems. Once he started having this, his eyes got much better.

Reptile calcium suppliment

This time of year our aquatic turtles are in their retreat outside, so they eat fresh from the garden plants growing for them. But I was worried that they were not getting enough nutrients as they would if eating the commercial foods, the calcium suppliment is one way I can insure that they will remain healthy through the summer while only eating greens and fresh foods

Great for treating MBD in snakes

Want to preface this with added D3 being unnecessary for supplementation for most lizards, from what I recall. But this is not about lizards. Metabolic bone disease is EXTREMELY rare in snakes because it is caused by deficiencies, and generally, at least one would hope, they are fed an appropriate diet as carnivores and born appropriately sufficient. However, I have garter snakes and the breeder of one was irresponsible; she was born from an unhealthy mother and did not start out with enough nutrition. Almost a year of many questions and vet visits later and she finally was diagnosed with MBD at a young age. At that point she had seized and almost all bones in her body began breaking down (I had 0 idea that was what was happening to her, but she was clearly unwell and 1 vet suggested palliative care). First thing I did was buy this supplement, apply it to ALL her meals, and get some UVB on her - and switch her to reptilinks food once she was eating regularly again. She doubled in size within 6 months. Long story short, MBD is NOT curable but it is possible to completely halt its progression by getting the animal back to baseline and healthy, which also re-strengthens the bones and muscle tone. She will never relapse again, because she is on an appropriately nutrient-dense diet (which was impossible with how young she was when symptoms began), and is extremely healthy at this point. She leaves me and veterinarians in awe. She turns 5 years old this fall. This supplement (and my hope in her) is directly responsible for saving her life. I am buying it again for her tankmate who is slow to pass her "slugs" yearly because added calcium can help prevent dystocia as well.

Red Foot Tortoise Repti Calcium

This was a waste of money for me because my red foot tortoise will not eat his food when I sprinkle this on it. Any product that the consumer purchases for the first time is a risk of not working for you. He will 'peck' at a calcium block.

Quality is great. I received my item so I turned it around to check expiration date but it was all erased so I couldn't make it there date. My previous one was expired and that's why I ordered again.
