5 Things You Need to Know About Choline

Choline is one of the most undervalued – and often overlooked – essential nutrients. In fact, nutrition experts estimate that as many as nine out of 10 adults fail to get enough to support the body’s basic needs.1 If you need inspiration to add more choline to your daily plate, check out these five reasons to start today:

1. Choline delivers whole body benefits

Choline is a building block for phosphatidylcholine and other phospholipids required by all cell membranes for structural support and cell signaling function. It’s also a building block for acetylcholine, an important biochemical messenger for nerve cell communication.

2. Choline supports liver function and lipid metabolism

Choline-derived phosphatidylcholine is a component of very low density lipoprotein (VLDL) particles produced by your liver. VLDLs serve one very important function: To move fatty triglycerides out of the liver. Phosphatidylcholine helps by making VLDLs water-loving molecules that can package triglycerides, transport them through the bloodstream, and deliver them to fat cells for storage or muscle cells for immediate use. Phosphatidylcholine is also a component of bile, produced by the liver to aid fat digestion.

3. Choline activates numerous bioactive compounds

Choline and its metabolites are a key source of methyl groups needed for healthy cell function, gene expression, detoxification and more. In fact, your body’s biggest demand for choline is supporting biochemical pathways requiring the transfer of methyl groups. It’s even at the core of healthy homocysteine metabolism, which is an emerging biomarker for heart health. Adding a methyl group (with the help of vitamin B12 and folic acid) converts homocysteine into the amino acid methionine that, in turn, supports even more methyl group transfer reactions.

4. Choline is found in common foods

You can boost your choline intake by eating more choline-containing foods such as beef liver, eggs, meat, fish, poultry, soybeans, milk, and cruciferous vegetables like broccoli, cauliflower and Brussels sprouts. Men and nursing women need at least 550 mg per day, while women need at least 425 mg (at least 450 mg during pregnancy). By contrast, the average daily intake is reported to be much less at 300 mg.2

5. Choline SR is a convenient way to fill the gap

Choline (Sustained Release) is a convenient way to fill any potential choline gap between what your diet supplies and what your body really needs. It’s a daily supplement formulated to deliver exactly what your body needs: highly bioavailable choline with advanced delivery technology for optimal absorption. Plus, Choline SR contains 300 mg of choline per serving, which is 54% of the Daily Value for choline (550 mg), making it an excellent source of this underappreciated, but oh-so-important, nutrient.

Product Description

Choline 300mg Sustained Release (SR) is ideal for adults who want targeted nutritional support for healthy liver function and lipid metabolism, as well as whole body support for optimal cell function at any age.*

Choline SR provides an excellent source of choline with 300mg per tablet. As a building block for phosphatidylcholine, choline supports cell membrane integrity and cell signaling, fat digestion and liver function and lipid metabolism.*

In the liver, choline-derived phosphatidylcholine helps transform VLDL (very low density lipoprotein) particles into water-loving molecules that can shuttle triglycerides through the bloodstream to fat cells for storage or muscle cells for immediate use. Choline is also a building block for acetylcholine, an important biochemical messenger for nerve cell communication.*

Yet the body’s biggest demand for choline is as a source of methyl groups needed not only for healthy cell function, but also for gene expression, detoxification, and more. Choline is even at the core of a healthy homocysteine metabolism, which is an emerging biomarker for heart health.*

Choline SR can be part of a pre- or post-natal supplement plan to help mothers-to-be and new moms fill any nutrient gap between what they consume and what a baby’s brain needs to thrive.* Choline plays a key role in fetal development, especially brain development, which is particularly rapid during the third trimester of pregnancy. For this reason, the recommended intake for choline is high for pregnant women (450 mg/day) and even higher for women who are nursing (550 mg/day).
