I know Dan also uses zinc frequently as part of his daily regimen along with o3 supps
Here's some I found so far:
Zinc and acne:
In a double-blind investigation of 54 patients suffering from acne vulgaris, the effect of 0.6 g of oral zinc sulphate daily versus placebo was studied. During the active treatment period of 6 weeks, the acne improved by about one-third, as rated with a score system. Clinical comparison with placebo showed the result of zinc sulphate therapy to be slightly, but statistically significantly better. Various methods for the clinical evaluation of acne were studied. Counting of acne lesions was found to be a more precise method than assessment according to the opinion of the patients and the assessment of colour photographs. The correlation between the results obtained by lesion counting and evaluation by photographs was low, as was also the reproducibility of photographic assessment.
In accordance with a randomized double-blind experimental design, capsules of zinc sulfate, 440 mg total daily dose, and lactose placebo were administered orally to 10 normal Caucasian males for 3 weeks. Sebum secretion rates and serum zinc levels were determined prior to and following treatment. There was a statistically significant change in the before and after mean sebum secretion rates of the zinc group when compared with those of the placebo group (p less than 0.028). The results of this preliminary study indicate that supplemental zinc sulfate may reduce the quantity of skin-surface sebum. Further investigation is warranted.
Zinc and Rosacea:
BACKGROUND: Rosacea is a skin problem not uncommonly encountered world-wide. There is a need for an effective and well-tolerated treatment for this disease. OBJECTIVE: To evaluate the efficacy and side-effects of zinc sulfate in rosacea in a randomized, controlled, double-blind trial. PATIENTS AND METHODS: Patients with rosacea who attended the outpatient Clinic of Dermatology and Venereology in Baghdad Teaching Hospital were recruited into this study between October 2002 and August 2004. A disease severity score was calculated for each patient. The patients were randomly allocated to receive either zinc sulfate 100 mg or identical placebo capsules three times per day. Zinc sulfate and placebo capsules were given in a double-blind manner. Following 3 months of starting the treatment, the patients crossed over, i.e. patients on placebo crossed over to zinc sulfate and those on zinc sulfate crossed over to placebo. RESULTS: Twenty-five patients with rosacea were included in this study: 16 (64%) females and nine (36%) males. Nineteen patients completed the study: 11 (58%) females and eight (42%) males. Patient age ranged from 21 to 64 years with a mean +/- SD of 48.2 +/- 9.3 years. Duration of the disease ranged from 1 to 14 years with a mean +/- SD of 4.4 +/- 3.2 years. In the group started on zinc sulfate, the score before therapy ranged from 5 to 11 with a mean +/- SD of 8 +/- 2.0. The mean started to decrease directly after the first month of therapy with zinc sulfate to a significantly lower level. After shifting to placebo treatment, the mean started to rise gradually in the fifth month but remained significantly lower than the levels before therapy. In the group started on placebo, the score before therapy ranged from 5 to 9 with a mean +/- SD of 7 +/- 1.3. The mean remained high in the first 3 months of therapy while the patients were on placebo. After shifting to zinc sulfate, the mean started to decrease after the fourth month to significantly low levels. No important side-effects were reported apart from mild gastric upset in three (12%) patients on zinc sulfate. CONCLUSION: Zinc sulfate was found to be a good option in the treatment of rosacea, as it was safe, effective and lacking important side-effects.
How much zinc is needed, and how much gets blocked:
50 mg daily is highly adequate, which at least half to 70% is used by the body. Considering you only need 11 mg a day to function fully, 25 mg is overly adequate. Reasons why in this post as to the interactions along the way in the body with zinc.
