Well, I can say for sure that 100% pure Biotin is water-soluble. And, it does not need warm water to dissolve.
I use 20oz/500ml bottles with the "sports cap", which are stored in the kitchen.
Each evening I measure 300mg (maybe + 1 or 2 mg) remove the bottle cap, and tip the measured Biotin in.
Over the next 4-5 minutes the Biotin sinks to the bottom of the bottle, and is half dissolved by the time it gets there.
The bottle is then inverted a few times, and left to stand overnight.
In the morning it will be inverted couple of times, observed to make sure that no particles remain undissolved, and then I take a pull on it regularly thru the day.
By the evening, there is just enough left to wash down the regular medication.

Thanks!
My chiropractor told me yesterday that Biotin was water soluble. Just wanted another opinion from someone here as I had read elsewhere that it was.

According to Sigma-Aldrich, the water solubility is 0.2 mg/mL.
http://www.sigmaaldrich.com/catalog/pro ... rodRecCold
20 fl. oz. is 591.5 mL. Thus, 118.3 mg of biotin should dissolve. This is less than half of the 300 mg which raises some interesting questions. Either Sigma has misreported the solubility, or perhaps there's something different about the bulk biotin.
Other sites report similar water solubility for biotin...
22 mg/100 mL = 0.22 mg/mL
http://www4.mpbio.com/ecom/docs/proddat ... %29/194634
220 mg/L = 0.22 mg/mL

The Biotin does not have to completely dissolved, it just needs to be suspended in the water so you can easily swallow it with the liquid. Biotin is a very fine power and easily mixes with water.

Yes, it's probably a colloidal solution of suspended particles. This can be easily confirmed by shining a laser pointer through the solution. If you can see the laser line going through the solution, then it confirms the colloidal properties. This is known as the Tyndall Effect.

I had never come across Tyndall scattering, so I reached for my laser pointer - and the batteries were dead!
So I got out my backup pointer - and the batteries were dead on that one as well!
Cut to the chase - new batteries, and there is no difference between a bottle of spring water, and a bottle of the same water containing 300mg of Biotin.
This argues that I have a solution, not a suspension. Against that, ElliotB's point does have a certain feel of "rightness".
However, none of the values for Biotin solubility, that I can find, specify the temperature of the water. I have seen a statement that Biotin will NOT dissolve in room temperature water, but that the water must be WARM. In logic, the temperature must play a part.
I guess that until I find a reason to change, I will stick to my current routine.

Whether the Biotin dissolves is, IMHO, irrelevant. You just need to consume it one way or another.

Some laboratory tests may potentially be distorted by CERENDAY®
These are tests that require the use of a biotin-based reagent such as some immunoassays (see list of parameters below) and tissue pathology examinations.
Depending on the method used, results can be falsely low / negative (e.g. sandwich immunoassays) or falsely high / positive (e.g. competitive immunoassays).

Don't see a reason to be concerned if it's mostly dissolved, totally, or not at all. In pill form, it's not dissolved at all when you take it. It just whether or not its in your body that's important. Being 'water soluble' basically is just important in that it doesn't store in your body fat like other vitamins do, and excess gets excreted pretty quickly. Vitamins that are stored in your fat (D3 for example) can build up to toxic levels eventually and much easier.
It does fwiw dissolve completely at room temp. Just not immediately. Give it a minute and a couple shakes of the bottle and its gone IME. The stuff I made last night went in the fridge for this morning. Completely dissolved as far as I can tell in cold water. It probably just took longer. Creatine, which I've been using off an on for a couple decades is also water soluble. Eventually. If you have no patience you drink wet sand, no big deal. If you have no patience and don't want to drink wet sand, you buy it in pill form. It still digests the same.

After NHE brought up the Tyndall Effect, I got to playing with a laser.
I think what happens is that the water dissolves as much Biotin as it can - so that we have a saturated solution of Biotin - and the remainder is then a suspension in that solution.
To all appearances, my 300mg had dissolved totally at room temperature. A laser in a darkened room showed a very faint trace - implying a suspension.
But, to paraphrase ElliotB, does it matter as long as you get the right dose?
As for the effect of hi-dose Biotin on blood tests, I have found this reported as far back as August. The link to Medday does not work for me, and I certainly want more data on this. There is another potential affect I would like to see nailed down - does Biotin affect the "dip-test" used as a first screen for a UTI? This could potentially affect a lot of people with MS.

And buried in the middle of that long, long, list was the one I was worried about - PSA.
This is for Prostate Specific Antigen.
An annoying test in that a positive result can mean more than one thing. An enlarged prostate, prostate cancer, or both. It is known that the test can be skewed by a UTI. i am in the middle of an investigation in this area and the next step but one may well involve a blood test for PSA (depends on a dip for UTI) so I shall have to to quit Biotin a couple of days before.
Thanks Poet.

It might be helpful to know what type of test is used in order to know if the potential interference might raise or lower the results.
