solaray - emulsified dry vitamin a, 25000 iu- 60 count
Here is the one Ed has been recommending. I found it at a local Vitamin Cottage. You will have to regrind it into smaller particles for it to stick well. I use a mortor and pestle but before that I used a spoon and a nylon cutting board.

That product is a combination of beta carotene and rentinyl palmitate. I thought Ed recommended against the beta carotene form of vitamin A.
I think maybe this one - http://www.smartbomb.com/p/Source-Naturals--Vitamin-A-Palmitate-10000-IU-100-tab/110823.html

heres a list of retinol suppliers. dosage in the small quantities needed will likely require the use of a highly accurate scale (milligram would probably be appropriate)

Went back and searched some posts on vitamin A. It was Ed's recommendation not to use a vitamin A source that was 100% beta carotene. So that combination product looks to be a good one to get.
THANKS.
The beta carotene appears to be fine as a cutting agent. Just dusting the flies at least once a month actually works pretty well for me. I know Dr. Wright recommends once a week.

sorry to get too far off topic, but im interested in purchasing large quantities of retinol powder (99%purity) and distributing it to other members since finding a good source isnt too easy. however i certainly dont want to create a supp, that will harm the frogs so dosage will be key. i like the idea of using beta carotine to "cut" the retinol with but i'd like to find out more about ratios of each. please feel free to PM me or chat on the subject.
thanks,

I have some.
My 'worry' is dosing....
Repashy has Vit A,
Dendrocare has Vit A,
Superpreen has Vit A
and I use them in rotation already....that said 'everyone' is touting the benefits of extra Vit A supplementation....
hence the feeling that Vit A cures all.
Do we all start crushing Vit A human grade tablets and supplementing more FF's???

BUMMER, I just placed an order for some. I guess let me know when you run out and need some
When are you home for the summer? I still need to hear about your trip to Peru.
Hi Shawn,
There is a risk of overdosing and I have concerns if people move to a easily dusted retinol only product. If we are willing to look at the empirical anecdotal evidence we can see that at least before the modification of the Repashy supplements, just using those supplements did not resolve symptoms of hypovitaminosis.
I ran a number of trials with both D. ebraccata and R. ventrimiculatus at work and replicated them at home with the hourglass treefrogs.
What looked to be poor fertilization and developement of eggs and SLS did not change significantly with the addition of dusting supplements containing vitamin A as retinyl palmitate. Once I added the dry vitamin A as a dusting supplement once a month, I saw an improvement in fertility, development and decrease in SLS. Once I went to twice a month, all of those issues disappeared and even after reducing the dry vitamin A to once a month I did not see a reoccurance of those issues. In several batches at home, I stopped using dry vitamin A for several months and just continued the Repashy and Dendrocare supplements without any decrease in fertility or development.
I want to move this over to trials with egg feeders as I think that is going to tease out a little more detail along with some more color trials.
We can probably extrapolate a RDA range using data from reptiles and birds but the issue is quantifying the amount that is actually sticking to the flies under different conditions....
Ahh, you need to consult me before purchasing any more supplements, second time this year!BUMMER, I just placed an order for some. I guess let me know when you run out and need some

Ed, I was concerned as well about the possibilities of overdosing. Did you dust with pure vitamin A or did you cut it at all?
I was tossing around the idea of cutting it with a few fillers such as glucose, sorbitol, fructose, whey or corn starch, but had concerns of effects to the darts diet, especially the sugar based products. I had also thought about mixing crushed vitamin A into my older supplements that are out of date.
My main concern of creating a mixture is the proportions. Is there any benefit to providing a gradual supplementation of vitamin A in lower quantities with frequent dosing instead of a heavy dose once every couple of weeks?

They're out of stock. I ordered some a few weeks ago and I'm still waiting for them to get back in stock.
