– Why are there so many B vitamins but not multiple of other letters. What’s the difference between them all?

Question

I’m eating cereal right now and it says it’s a good source of 5 B vitamins. You always see Vit B6 or B12. What are all these vitamins and why is there only one A or C vitamin?

Answer 1

I actually had a question about my B12 vitamin today… my vitamin D supplements come in 125% the daily dose (25 mcg) but my B12 has a whopping 35417% of the daily dose (850 mcg)!

Is there a reason for this?
