I was wondering whether adding the following B-50 to my multivitamin regime would be a good idea or whether it's overkill. Here is the B-50 content (Nature's Harmony brand - not sure if this is standard):

Pantothenic Acid (is this the same as B5?) 100 mg
B1/Thiamine HCI 50 mg
B2/Riboflavin 50 mg
B3/Niacinamide 50 mg
B6 50 mg
Folate 1 mg
B12 75 mcg
Biotin 75 mcg
Choline 50 mg
Inositol 50 mg

My multivitamin (Genuine Health Multi + Daily Joy) contains the following B's:

B1/Thiamine HCI 25 mg
B2/Riboflavin 50 mg
B3/Niacinamide 25 mg
B5 25 mg
B6 25 mg
B12 1000 mcg
Folic acid 800 mcg
Biotin 25 mcg

Any thoughts? Also, is it better to take B vitamins earlier in the day?
