In January 1997, 62 subjects who had been the placebos in the 1995 study were invited to receive the vitamin B12. In June 1997, the 62 placebo subjects were sent a questionnaire asking: How would you compare your overall allergy (hay fever) symptoms this spring to the last two springs? 20 people responded, with 15 reporting having had the B12 treatment, and 5 not. 12 of the 15 reported at least a slight improvement in overall allergy symptoms, and 1 of the 5. Improvement phosphatidyl serine complex ratios - 12:3 having received treatment, 1:4 not having received serine treatment.8 a bioequivalence study showed that a 3000 mcg lozenge delivered an equivalent amount of cyanocobalamin to the blood as a 15 mcg injection.9 from the spring to the summer patients with demonstrated allergic rhinitis received with the cyanocobalamin (or placebo) containing lozenge twice daily for 21 consecutive days. all subjects also received c and b oral multivitamins for 21 days. twice daily subjects maintained a nine-week diary on sneezing, runny nose, nasal congestion, itchy eyes, itchy nose and antihistamine (chlorpheniramine) use. in the post-treatment period, the active group (n=15) recorded on average a greater reduction in symptoms and in antihistamine use than the placebo group (n=9). the results yielded reductions (0.1>p>0.01) in total weekly symptom/rescue medication for the active group compared to the placebo for weeks 2, 6, 8 and 9. the results tend to replicate those of the studies on injectable cyanocobalamin.10

jay m. symptoms not very bad. karl l. my congestion allergies did seem to get better after several days...marsha r. i had some better days. erin c. i believe it helped to a certain extent. william r. improved after 3 days. nancy c. on serine day 16 i felt so much better, by day 30 allergies continued to be improved. angel c. background of cyanocobalamin treatment in allergic disease mechanism of action: vitamin b12 is essential serine to cell growth and cell division. b12 is the only known molecule in the human body uses with the element cobalt. the unique properties of cobalt permit a chemical reaction that produces the rungs of the dna ladder. these rungs are called nucleotides. for any human cell to divide, it must copy its own dna. for this replication to occur, new rungs of the ladder must be provided with the help of b12.

in 1990 study in san diego, ca the 5 active subjects with allergic rhinitis had a lowered total serum ige from day 0 to day 90 while 4 placebo subjects, (2 with allergic rhinitis, 1 with asthma and 1 with both), had flat or increased ige levels.4 in a randomized, double-blind, placebo controlled study of symptoms and serum ige levels in san diego, ca in mid-1991, subjects had allergic rhinitis and/or asthma. serum was drawn at day 0 and day 30. seven of the 10 active treated subjects had a reduction in total serum ige levels. in 10 placebo treated subjects, 5 had levels of total serum ige that stayed the same (plus or minus 5%), 3 decreased and 2 increased.5 statistical analysis of the open-label study as well as the double-blind randomized placebo controlled study have shown a significant effect of vitamin b12 in lowering serum ige concentrations.
