Dear Dr. Allen:

The price of our Kapseal Combex has all ways been
higher thah the product you refer to.

However, I believe you will find that Kapseal
Combex is 33% to 50% higher in potency in several of the important
factors.

I would appreciate you comparing the two products
as to their potency, before buying.

Kapseal Combex

Vitamin B (1) 500 International Units
Vitamin B (2) 200 Sherman Units
Vitamin B (6) 250 Gamma
Pantothenic Acid 500 Gamma
Nicotonic Acid D Mee
Sincerely,
vy ey
