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.

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!

Works well.

I have been taking this for quite a few months now. I work in the hospitality industry with food and did not want to get the usual cough and colds I get every year. I have not had a cough or cold since taking this. It doesn’t taste the best but well worth taking it to keep the bugs away. I will keep taking it as I think it definitely works for me.

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 tasting. The flavouring is not too citrusey so doesn\'t cause me reflux- usually and is easy to take. It mixes well and seems to do the job. Would be good to have a 1/3 tsp measuring spoon in there though as 1000 mg (1/3 teaspoon is a very common dose) and is hard to measure exactly with an ordinary teaspoon.

New formula is great
5th Oct 2019
We\'ve been using this for years through all it\'s formula adjustments. This new one isn\'t as sweet, but my kids still happily drink it. I find it\'s great especially if I feel like I\'m getting sick - it seems to knock it on its head

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.
