B Complex

B vitamins, including B12 and B6, are important for healthy immune response. Yet many adults are deficient in them, which may negatively affect immune health.


Unfortunately the amounts of the individual B vitamin in many vitamin B complex supplements are seriously unbalanced.

This is particularly true of the high strength B Complex supplements – where they may have 50mg or even 100mg of each of the individual B vitamins.

Ideally the complex should contain vitamins B1, B2 and B6 in equal amounts. B3 and B5 should be 10 times the amount of B1, B2 and B6.

Cause deficiency

Comparatively high B1, B2 or B6 will drive out B3 and B5, causing deficiencies of these two vitamins.

The only well-balance B Complex that I am aware of is Solgar’s Vitamin B-Complex with Vitamin C.

Here is the list of the amounts of individual B vitamins in Solgar’s B complex:-

Serving Size: 2 Tablets provides:
Vitamin C (as L-ascorbic acid) 500 mg
B1 (Thiamin) 10 mg
B2 (Riboflavin) 10 mg
B6 (Pyridoxine) 10 mg
B3 (Niacin) 100 mg
B5 (pantothenic acid or calcium pantothenate) 100 mg
Folic Acid 100 mcg
B12 (cobalamin) 25 mcg
Biotin 25 mcg
Inositol 100 mg
Choline (as choline bitartrate) 41 mg

Solgar appear to have updated the label on their B Complex with C:-

The amounts of individual B vitamins are the same, however, so either product will do.
