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.
