The Living Force
Thank you MK Scarlett for your feedback, in the last 5 days I took around 14:00 the vitamin D, Magnesium first and after about 15-20 minutes later I took 400 mg of Quercetin, 25 of zinc piccolinate and 3 gr of Vitamin C on an empty stomach.I do it sometimes, when needed, and never had any irritation to the throat.
@Andrian, I take Quercetin 500 mg with zinc 30 mg as well as Magnesium Malate and Melatonine 2 g on evening before going to sleep.
So, as I take Magnesium at the same time and that I'm going to sleep, I don't take Vitamine C around that time.
And I don't think that Quercetin 400 mg is a high dose, as shown in this study published in NCBI, where it is said that Quercetin exhibited safety (up to 5g daily):
I don't know when you took the Zinc and Quercetin: Was it morning, afternoon or evening? Close to a meal, or on an empty stomach?
I don't have the information at hand, but I remember reading it somewhere that it is better to take Zinc in the evening, but maybe others will have another opinion/knowledge on this. It seems that one should not take it on an empty stomach, that's what I've just find from Mayo Clinic:
As far as I understood from the above it will be wise to take them before or after a meal.
