Oh Mama! Bars Containing Martek DHA™ Now Available at
Motherhood Maternity Stores Nationwide

Nutritional Bars for Pregnant and Nursing Women Contain 100 mg of non-fish DHA

COLUMBIA, MD, July 11, 2005 –Expecting and nursing moms may not be getting enough DHA (docosahexaenoic acid), an omega-3 fatty acid essential for their babies’ brain and eye development, because dietary sources are limited. Now they only have to visit one of their favorite stores to get a non-fish source of DHA. Oh Mama! nutrition bars containing Martek DHA, the all-natural vegetarian source of DHA added to infant formula, are now available at over 700 Motherhood Maternity stores nationwide.

Fatty fish and organ meat are the primary dietary sources of DHA, making it difficult for most people to get enough of this important nutrient through diet alone. Americans tend to have among the lowest DHA intake in the world, and pregnant women, who are cautioned by the U.S. FDA and EPA to limit their consumption of certain fish due to concerns about mercury intake, may get even less DHA in their diets.

The amount of DHA in a mother’s diet determines the amount of DHA passed on to their developing baby through the placenta during pregnancy, and through breast milk after birth. Studies have shown that maternal DHA supplementation throughout pregnancy and nursing results in long-term cognitive and psychomotor advantages in children.

Oh Mama! Bars, which contain 100 mg of Martek DHA, offer a convenient and safe dietary source of DHA for pregnant and nursing women. Martek DHA is the only DHA accepted for use in U.S. infant formulas. Developed by a process that extracts DHA from algae under tightly controlled manufacturing conditions, Martek DHA is free of chemical pollutants and toxins that may be present in certain fish and fish oils. Martek DHA is produced under U.S. FDA current Good Manufacturing Practice (cGMP) conditions and Martek’s plants are regularly inspected by the FDA.

“This is great news for new moms and moms-to-be who are concerned about getting enough DHA from a safe source while they are pregnant and nursing--a time so critical to their developing baby. Now they can get the same DHA trusted for use in infant formulas through a great-tasting nutrition bar widely available in stores throughout the U.S.,” said Henry "Pete" Linsert, Jr., Chairman and CEO of Martek.

High in protein and low in both calories and fat, Oh Mama! Bars were created with the help of doctors and nutritionists to ensure pregnant and nursing women get the right amount of the most important vitamins and minerals. The bars include important nutrients not found in most prenatal vitamins, such as DHA, magnesium, and iodine. They are available in 3 different flavors—yogurt honey, chocolate peanut butter and frosted white raspberry. For more information, visit www.ohmamabar.com
