Vitamin B3 (niacin) won't induce hypoglycemia.

Many people are sensitive (or "allergic") to supplements, including their
binding agents and the raw materials they were derived from (ex, corn and
vitamin C).  This explains why a lot of people feel worse after taking them.
Their body expends energy to the get rid of the allergic or "offending
substance".

Various energy-based therapies, including NAET

sensitivity/allergy (to virtually any substance according to its proponents)
