Clinicians Hi-Dose Vit C Powder is a potent formulation containing two forms of Vitamin C that may support the immune system in times of stress. Each teaspoonful provides a high 3550mg dose of Sodium ascorbate and Ascorbic acid, buffered forms that are well tolerated and easily absorbed by the digestive tract. 
Hi-Dose Vit C can be taken every 2-3 hours when ills and chills strike to provide acute support to the immune system.  Studies show Vitamin C absorption is greatly increased in individuals when they are unwell before reaching bowel  tolerance and provoking side effects. This is due to increased support required for immune system function. Hi-Dose Vit C is also appropriate for daily use as it supports stress hormone production from the adrenal glands during times of stress. 
  • This product may cause bowel looseness. 
  • If you are on any medication, please consult with your health professional before taking this product.

My Secret Weapon!

Cannot do without this. Have a teaspoonful every morning mixed with 1/3 cup hot water and wash my collagen tabs down with it. I look forward to my morning ritual and am finding I have no more issues with sinus, the colds are passing me by and best of all, the dark red bruising I'd get from knocking my arms or hands (I'm 60) has stopped occurring. A naturopath recommended Vit C to help this and boy! has it worked!! Love the taste also. Repeat order for this product!

I work in a large open plan office with bad air con and honestly there is not a time EVER when people are not sick. In winter it is far worse - many people have a bad cold x3 over that season. I take a small does of this daily at work with camomile tea and I have not been sick with a cold once. I even dish it out to colleagues when they are unwell. Love this product, it has a pleasant mild taste (not at all sweet). I directly attribute it it keeping well in the office!
