Plants contain D2, ergocalciferol. Ergocalciferol has been found to be much less efficient in calcium metabolism than cholecalciferol.
in some species, such as rats, vitamin D2 is more effective than D3.
A study of captive iguanas, however, at the National Zoo, found that when they were kept under experimental very high output (VHO) UVB fluorescents, they developed a condition that, the researchers said, would, in mammals, be considered vitamin D toxicity - too much D.
First off, I'm assuming you've completely forgotten about the diurnal geckos. Secondly, even most nocturnal geckos HAVE been shown to bask. It's been shown several times that assuming nocturnal species don't bask is erroneous. Thirdly, it has also been shown in many reptiles that although they may not bask in direct sunlight, that even when living under the canopy of dense foliage, enough UVB gets scattered to reach and impact the health of particularly delicate skinned reptiles such as geckos.I see your point Wes, but what about wild geckos? They do not bask, so how do they get this needed D3, If it is needed?
Agreed, 100%. That goes, in my opinion, for overly strong UV bulbs as well. Folks, do yourself a favour and buy good vitamins from your veterinarian. Also make sure your tegu gets good UVB exposure (caveat: good does NOT mean excessive) and a varied, balanced diet.What is the safest way to keep tegus? IMO, it is not taking risks with unproven products. Just my honest opinion.
Ray Sahelian, M.D.: Source of cholecalciferol or vitamin D3
Cholecalciferol has an origin from animal products such as sheep wool. The sheep are not killed. The wool is sheared, and lanolin from the sheep wool is chemically altered in the lab to produce vitamin D3 or cholecalciferol.

prior to this happening I started using calcium/D3 when I made her food and after a while of using it is when I started noticing these problems to the point where she has a hard time swallowing food now.

I would not doubt it could cause a whole host of problems in tegus.

I will feed mine a proper diet and provide good UV lighting when they are inside.
How often were you using the D3? How old is she? There are things to consider when giving extra D3. Your Tegu is showing signs of too much D3. I am afraid you may have given too much not realizing it.Most carnivores get their d3 from the animals they eat. When they are adults this is usually enough to keep them going. Young lizards on the other hand can use it. I would really like to carry the subject of How to properly give supplements to lizards . To another thread. There are right ways and wrong ways of doing it.angelrose said:VARNYARD said:angelrose said:Bobby as you know my colombian is still not well and having difficulty breathing.

before I started using D3 my colombian was spunky and never a problem and now this after giving her D3 for a while. she is still having a hard time breathing. I'm scared she is not going to make it. I have been feeding with a syringe and if it's too much it will come back up. I am still feeding with a syringe and she's been holding on but still struggling to breath and keep down her food.
so I have been feeding with the syringe in small amounts throughout the day.
is this reversible ?
