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.

I would appreciate if it was without flavouring and Thaumatin

It is a fair price, but I stopped buying this one as it still contains so called natural flavouring which still is artificial. Also would appreciate it without Thaumatin ( which is a sweetener even though plant derived ). Switched to Bio Balance Esterified Vitamin C ( here on healthpost ) as it comes in a glass bottle and is without any flavouring or sweeteners.

This is the best vit C supliment I have tried, I have been taking it for over 2 years now. It really suits me as I can get the high dose my body requires for my condition also it is a way of getting me to drink extra water. I have 3 x per day in 500mls water...

I already take a daily vitamin C, and got this for those times when extra support is needed. One of those times was last week, when I woke with a sore throat on Friday. I took a level teaspoon in water before breakfast, before lunch, and before dinner. This was less then the every 2-3hrs recommended on the label for immediate support, as I was still also taking my other vitamin C. Unfortunately I experienced the 'bowel looseness' that is warned of on the label. Glad I only got the 75g size as I won't be having any more of this. Taste is fine, and it dissolved well in water so not a complete disappointment. Potentially would be a higher rating if I was using this as my daily vitamin and only taking 1t per day.

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!
