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.

Good solid product for immunity, healing and general health. Because of powder form, it provides flexibility in dosing depending on your needs. Since it has changed formulation recently, my family have gotten used to the taste. It taste OK but some might not like it.\nMy family has been taking this daily for years.

Great value supplement

So many people moaning about the sweetness! Seriously - get over it. It\'s a supplement, not a treat. Perfectly good formula that gives you everything you need, nothing you don\'t.

Love this product

I was recommended the high dose vitamin c four years ago by a nutritionist and now I always have a container in my cupboard. All the family use it and like it. Plus it keeps us well over winter and knocks any emerging sniffles or sore throats on the head.

Great product but please go back to original taste!

Love this product, is a great way to up your vitamin c intake easily. Unfortunately with the changes, it first became very sweet (which a lot of people complained about, we didn’t mind too much) but now we notice it has changed again and is now not sweet enough! The kids don’t like it! Please Clinicians, go back to your original formula!

Way too sweet

I used to regard this product as very good but they have changed the recipe and now it is way too sweet. Such a shame.

It\'s a real pity when a company takes a great product and changes it. This used to be my favourite vitamin C - but then the formulation changed and now it tastes ghastly! Yes, it may have been a tad sweet (thaumatin and stevia) but using less powder was a simple solution. Am very disappointed.

Still good

I re-purchased this product despite the reviews around taste, because it still delivers. Yes, the taste is much sweeter but it’s still consumable.
