Manufacturers are responsible to ensure the safety, but do not need to <i>prove</i> the safety and effectiveness of dietary supplements before they are marketed. Dietary supplements may contain multiple ingredients, and differences are often found between labeled and actual ingredients or their amounts. A manufacturer may contract with an independent organization to verify the quality of a product or its ingredients, but that does <i>not</i> certify the safety or effectiveness of a product. Because of the above issues, clinical testing results on one product may not be applicable to other products.

Then they pumped 1 to 4 milk samples at the time they perceived the smell of eucalyptus on their breath which had been previously shown to be approximately concurrent. A total of 21 milk samples were obtained. Odor was rated by a panel of 3 to 5 experts as either smelling like eucalyptus or not. Fourteen of the samples had a distinct eucalyptus-like odor. Chemical analysis of the positive odor tests found 1,8-cineole in concentrations from 70 to about 2090 mcg/kg of milk, most in the range of 100 to 500 mcg/kg of milk. Samples with negative odor tests contained concentrations in the range of 0.98 to about 20.23 mcg/kg of milk. In one woman who donated 3 samples, the highest concentration of 71 mcg/kg occurred at 1.5 hours after ingestion, with concentrations of 1 mcg/kg before ingestion and 15 mcg/kg at 9.5 hours after ingestion.[<a class="bk_pop" href="#LM912.REF.7">7</a>]</p><p>Eight women had their milk analyzed for 1,8-cineole metabolites.

Baseline linalool concentrations in milk averaged 0.22 mcg/L (range 0 to 1.1 mcg/L). Milk samples contained linalool in concentrations of 0.12 to 15.24 mcg/L at 1 hour after eating, 0.03 to 6.44 mcg/L at 2 hours after eating and 0.01 to 3.73 mcg/L at 3 hours after eating. In the same study, the curry dish contained an average of 394 mcg of 1,8-cineole. Baseline 1,8-cineole concentrations in milk averaged 1.44 mcg/L (range 0.07 to 7.57 mcg/L). Milk samples contained 1,8-cineole in concentrations of 0.19 to 7.41 mcg/L at 1 hour after eating, 0.33 to 7.86 mcg/L at 2 hours after eating and 0.22 to 3.33 mcg/L at 3 hours after eating.[<a class="bk_pop" href="#LM912.REF.10">10</a>]</p><p>Twenty nursing mothers who were nursing their infants with a mean of 25 weeks of age were served a standardized curry dish that contained an average of 400 mcg of 1,8-cineole and 35 mg of linalool.

Peak milk 1,8-cineole concentrations ranged from 0.98 to 10.1 mcg/L. Linalool reached its maximum concentration in milk after 1 hour in eleven participants, after 2 hours in six, after 3 hours in two participants, while in one participant, the maximum was not clearly determinable. Peak milk linalool concentrations ranged from 4.13 to 18.91 mcg/L.
