Viridian High Twelve® B12 with B Complex 30's
- Product Review (submitted on 9 August 2018):
- Best quality b12 supplement. I'm vegan, and take this only once or twice a week. I had my bloods done and my b12 level was 525.5 pmol/l (considering 698 pmol/l is the highest) my b12 level was on the high side, and it was 5 days after taking this supplement. You don't need to take it everyday. It works very well.
