Ultralec
Also known as: Ultralec, deoiled lecithin, soy lecithin, phosphatidylcholine, Lecithin
Overview
Ultralec is a brand name for a type of deoiled lecithin, primarily composed of phospholipids such as phosphatidylcholine. Lecithin is a natural phospholipid complex found in many plants and animal tissues, commonly extracted from soy or sunflower seeds. It is widely used as a food additive due to its emulsifying properties and as a nutritional supplement to provide phospholipids and choline. Ultralec, specifically, is a dry, deoiled lecithin product derived mainly from soybeans, characterized by a high phospholipid content (approximately 50% more phospholipid strength than fluid lecithin), a bland flavor, low aroma, and water dispersibility. It is available in powder, fine granular, and granular forms, making it versatile for various food and supplement formulations. While lecithin as a nutrient and emulsifier is well-studied, direct clinical research on specific branded products like Ultralec is limited. Most evidence regarding health benefits relates to general lecithin or phospholipid supplementation.
Benefits
Lecithin supplementation, including products like Ultralec, primarily provides bioavailable choline, which is essential for maintaining cell membrane integrity and synthesizing neurotransmitters like acetylcholine. It may support healthy lipid metabolism and liver function, although direct clinical trials on Ultralec specifically demonstrating quantified clinical benefits are lacking. Lecithin-derived phospholipids can also improve the emulsification and absorption of fats and fat-soluble nutrients. Some studies suggest that lecithin can modestly improve lipid profiles, but these effects are generally small and inconsistent across research. Potential benefits may exist for populations with choline deficiency or increased choline demand, such as pregnant women or the elderly, but specific data on Ultralec for these groups are not available. No clinical significance thresholds or effect sizes are reported for Ultralec specifically, and the time course of benefits is not established, though general lecithin supplementation effects may require weeks of consistent intake.
How it works
Lecithin, including Ultralec, functions by supplying phosphatidylcholine, a crucial component of all cell membranes and a direct precursor to acetylcholine, a vital neurotransmitter. This contributes to maintaining membrane fluidity and integrity throughout the body. In the liver, lecithin influences hepatic lipid metabolism, aiding in the transport and processing of fats. In the brain, its role as a precursor to acetylcholine supports neurotransmission and cognitive functions. Furthermore, in the digestive system, lecithin facilitates intestinal fat absorption by acting as an emulsifier, breaking down dietary fats into smaller droplets. Deoiled lecithin, like Ultralec, is water dispersible, which enhances its absorption and bioavailability compared to fluid lecithin forms.
Side effects
Lecithin is generally recognized as safe (GRAS) by regulatory authorities, and Ultralec, as a purified lecithin product, shares this favorable safety profile. Common side effects are mild and infrequent, primarily involving gastrointestinal symptoms such as nausea or diarrhea. Uncommon side effects (1-5% incidence) include allergic reactions, particularly in individuals with a soy allergy, as Ultralec is typically derived from soybeans. Rare side effects (less than 1% incidence) are not reported, and no serious adverse effects have been documented. There are no major known drug interactions associated with lecithin. The primary contraindication for Ultralec use is a known allergy to soy or any of its components. Individuals with soy allergies should exercise caution or avoid this supplement.
Dosage
Specific minimum effective doses for Ultralec are not established. However, for general lecithin supplementation, typical daily doses range from 1 to 3 grams. This range is also considered optimal for general supplementation purposes. The maximum safe dose for lecithin is generally considered to be up to 10 grams per day. Ultralec can be taken with meals, as this may aid in the digestion and absorption of fats. Ultralec is available in powder and granular forms, which are optimized for blending and dispersibility, potentially improving its absorption due to its water dispersibility. No specific cofactors are required for its absorption or efficacy.
FAQs
Is Ultralec safe to use?
Yes, Ultralec is generally recognized as safe (GRAS) with a low risk of side effects, primarily mild gastrointestinal upset or allergic reactions in soy-sensitive individuals.
What are the expected benefits?
Ultralec primarily provides nutritional support by supplying phospholipids and choline, essential for cell membranes and neurotransmitter synthesis. It is not supported for direct weight loss or significant lipid-lowering effects.
When should it be taken?
It is generally recommended to take Ultralec with meals, as this can help enhance the digestion and absorption of dietary fats.
Can it cause allergies?
Yes, as Ultralec is typically derived from soy, it can potentially cause allergic reactions in individuals who are sensitive or allergic to soy.
Is it effective for weight loss or cholesterol?
No, there is no high-quality evidence specifically supporting Ultralec's efficacy for weight loss or significant cholesterol reduction.

- https://pubmed.ncbi.nlm.nih.gov/33976376/ – This systematic review and meta-analysis investigated the efficacy of various dietary supplements for weight loss. It concluded that lecithin or related compounds did not show a clinically significant effect on weight loss, indicating limited utility for this purpose.
- https://pubmed.ncbi.nlm.nih.gov/36891733/ – This systematic review and meta-analysis focused on the effects of phytosterol supplementation on lipid profiles. While phytosterols are structurally related to some lecithin components, the study did not specifically focus on lecithin itself, but rather on compounds known for their lipid-lowering effects.
