Is it okay to take apple cider vinegar. colloidal silver. vitamin c and B6 to boost white blood cells?

 
I am not a fan of colloidal silver. I do not agree with ingesting heavy metals such as this to increase activity of our bodies. I rather use nutrients which the body recognizes and utilizes naturally.
 
Boosting white blood cells is needed when they are low. Too high is not good.
 
Vitamin C is great.
 
Apple cider vinegar is an excellent digestive aid but not sure if it affects white blood cell count.
 
Vitamin B6 is good - make sure it is a quality B6.  This article may be of some interest.
 
A quality multivitamin is a good idea to support overall immunity and not imbalance a specific nutrient.
 
I suggest you consider:
Lypospheric Vitamin C
Optimal Multivitamin
Magnesium Plus
 
 
Combined, these should support increasing your white blood cells.
