All of the active B12 group reporting showed reduction in severity of symptoms ranging from 31% to 70%, while the placebo controls reported either no change or a worsening of symptoms. Wilcoxon-Rank of .002 for the end-points of sneezing, nasal congestion and runny nose; and p = .005 for IgE reductions. In 1992, the above mentioned data from 1988 on were presented by Dr. O''Connor to the FDA. The FDA panel acknowledged the safety of the treatment. The panel seemed progreens to be in agreement that the statistics indicated a significant reduction in IgE and that a quantitative drop in symptoms was demonstrated. In 1992, Belen Anibarro, MD, studied five children with asthma with metabisulfite intolerance confirmed by oral challenge testing. The test was repeated after premedication with 1.5 mg of oral cyanocobalamin. In four of the five patients treated, bronchospasm did not develop in the second metabisulfite challenge.6

In January powder 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 progreens 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, powder and 1 of the 5. Improvement ratios - 12:3 having received treatment, 1:4 not having received 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 progreens rhinitis received with the cyanocobalamin (or placebo) containing lozenge twice daily for powder 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 progreens compared to the placebo for weeks 2, 6, 8 and 9. The results tend to replicate those of the studies on injectable cyanocobalamin.10

A new HAY powder FEVER breakthrough clinically proven to reduce allergy symptoms and antihistamine use. How long were symptoms reduced? Studies showed a one-year reduction. How long? Yes, one year! this medication is a lozenge taken twice daily for 21 days. this medication progreens is non-drowsy, natural and available without a prescription. powder this medication is a 21 day treatment. this medication users report reductions in symptoms one year after completing the treatment without taking additional this medication. How long? Yes one year, compared to 24-hour antihistamines it''s much longer lasting. Patients known to have seasonal allergy were examined in clinical studies in five U.S. states by qualified medical doctors. Each patient was given either the real this medication or a placebo (a dummy treatment). Nobody knew who got what. Patients recorded in symptons diaries how bad their symptoms were during and after the treatment. About one year later, patients completed a second diary. 64% of the group of patients receiving this medication recorded less sneezing, runny nose and nasal congestion one year after completing the treatment in a clinical study. This compares to 35% of the placebo group.
