Night sweat has a lot of causes, the most important one is infection. If physiological causes have been ruled out, it can still be due to:

Medications 鈥?Taking certain medications can lead to night sweats. In cases without other physical symptoms or signs of tumor or infection, medications are often determined to be the cause of night sweats. Antidepressant medications are a common type of medication that can lead to night sweats. All types of antidepressants can cause night sweats as a side effect, with a range in incidence from 8 to 22% of persons taking antidepressant drugs. Other psychiatric drugs have also been associated with night sweats. Medicines taken to lower fever such as aspirin and acetaminophen can sometimes lead to sweating. Other types of drugs can cause flushing, which, as mentioned above, may be confused with night sweats. Some of the many drugs that can cause flushing include:
niacin (taken in the higher doses used for lipid disorders),
tamoxifen,
hydralazine,
nitroglycerine, and
sildenafil (Viagra).
Many other drugs not mentioned above, including cortisone medications such as prednisone and prednisolone, may also be associated with flushing or night sweats.

Hormone disorders - Sweating or flushing can be seen with several hormone disorders, including pheochromocytoma, carcinoid syndrome, and hyperthyroidism.

Hypoglycemia 鈥?Sometimes low blood glucose can cause sweating. People who are taking insulin or oral anti-diabetic medications may experience hypoglycemia at night that is accompanied by sweating.

Go with the old trial and error method. Stop taking one of your supplements, see what happens. Try it with all, sometimes one will not give this side-effect, but by taking 2 together you might be causing it and not know.

if you're looking for an alternative answer (?) after that extremely comprehensive medical-model one then...night sweats are caused by your astral body struggling to return to the body after travelling too far! i'm not saying i believe this in a literal sense but CAN say that getting my emotional and psychological health into better balance has stopped night sweats for me..... =P

I think if they haven't found anything then there isn't anything to find. Don't worry about them. I get night sweats as well and have for years.
