Numerous Sources of Choline

Choline for the Female Athlete

Choline’s potential benefits to brain health, liver function and cellular integrity are of particular interest to the female athlete.

There are good reasons why women of all ages should strive to maintain adequate levels of choline, and there is substantial information on its benefits to brain health, liver function and cellular integrity that are of particular interest to the female athlete.

Based on data from the National Health and Nutrition Examination Survey (NHANES) 2013-2014, women experience larger shortfalls in choline intake than men do. Choline plays a vital role in cell structure and function, fat metabolism and neurotransmission.1 Given that women depend on their bodies to be healthy and energetic, and their brains to function well, the need for adequate choline intake should be viewed in the context of everyday life, not just in the gym.

Choline provides critical benefits before, during and after exercise. It provides fuel for energy production. Choline consumption is especially vital to physically active people engaging in sustained intensive exercise, which depletes choline levels.2,3 Without inadequate choline levels, the body will break down cells to ensure the brain gets enough. Over time, this can lead to a detrimental buildup of fat in both liver4 and muscle cells.5

Replacing choline post-workout helps to maintain the body’s stores and ensures proper communication throughout the brain and to the muscles via the neuromuscular junction.6,7 Manufacturers are also recognizing the important role choline can play in sports nutrition products. According to product launch data from Innova Market Insights, sports nutrition is a leading market category for choline, with 6.1 percent of new product launches in 2017 in sports nutrition containing choline compared to just 3.8 percent in 2015—an increase of 61 percent in just two years.
