Rose hips.
I like the dosage of 500 mg that I take morning, noon, evening and bed time. That meets my goal of 2000 mg per day and I believe makes vitamin C present in my system most of the time. I believe the rose hips may be more bio available. I started taking 500 mg vitamin C with rose hips when I was 23. I am 69 now and have not been bed ridden with a cold or virus since.
