Sunflower Lecithin

A natural phospholipid complex

72,99 zł

Provides a natural phospholipid complex
Combines complementary phospholipid fractions
Sunflower-derived lecithin

Overview

A natural complex of phospholipids. Sunflower Lecithin provides molecules with a distinctive structure: one part is drawn to water, the other to fats. This allows phospholipids to arrange themselves into the double layers that form cell membranes, and explains lecithin's effectiveness as an emulsifier.

Sunflower Lecithin

Made for your daily routine.

Phosphatidylcholine is a prominent component of lecithin, alongside other phospholipids. This sunflower-derived ingredient provides a mixture of lipid classes rather than a single isolated fraction.

We use non-GMO sunflower lecithin with olive and rosemary extracts. These help protect the lipid mixture against oxidation during storage.

Sunflower Lecithin

Why do lecithin phospholipids matter?

Phospholipids, including phosphatidylcholine and phosphatidylethanolamine, form cell membranes and participate in lipid transport and signaling. Phosphatidylcholine contains a choline component, but 200 mg of phosphatidylcholine is not 200 mg of choline. This product is primarily a phospholipid source.

Sunflower Lecithin

What research informs Sunflower Lecithin?

Human studies show that phosphatidylcholine supplies choline but is metabolized differently from free choline salts. Controlled experiments have reported different TMAO responses under specific conditions. Research also describes phospholipids' fundamental roles in membranes and lipid metabolism. Evidence for a direct memory benefit from lecithin is mixed.

Science & sources

Understand the formula.

Research on lecithin extends beyond memory to phospholipid physiology, including cell membrane structure, lipid transport, and choline metabolism. Human studies also show that phosphatidylcholine is metabolized differently from free choline salts, providing context for discussions about TMAO.

These publications concern the studied ingredients or formulas. They do not all evaluate the finished Doctor Life product, and research results do not guarantee individual outcomes.

01The critical role of phosphatidylcholine and phosphatidylethanolamine metabolism in health and disease

Jelske N. van der Veen, John P. Kennelly, Sereana Wan, Jean E. Vance, Dennis E. Vance, René L. Jacobs

Biochimica et Biophysica Acta (BBA) - Biomembranes (2017), 1859(9 Pt B), 1558–1572. DOI: 10.1016/j.bbamem.2017.04.006; PMID: 28411170.

This review describes phosphatidylcholine and phosphatidylethanolamine as major phospholipids in mammalian cell membranes. The authors examine their roles in membrane properties, lipid and lipoprotein metabolism, and mitochondrial function. The publication provides context for whole lecithin, which naturally contains several phospholipid classes.

02Differential metabolism of choline supplements in adult volunteers

Katrin A. Böckmann, Axel R. Franz, Michaela Minarski, Anna Shunova, Christian A. Maiwald, Julian Schwarz, Maximilian Gross, Christian F. Poets, Wolfgang Bernhard

European Journal of Nutrition (2022), 61(1), 219–230. DOI: 10.1007/s00394-021-02637-6; PMID: 34287673.

A randomized crossover study compared several choline forms in healthy adults, including phosphatidylcholine. All forms increased choline levels, but phosphatidylcholine produced a later peak and, unlike the water-soluble forms, did not increase TMAO under the study conditions. The findings illustrate how chemical form can affect metabolism.

03Effect of Choline Forms and Gut Microbiota Composition on Trimethylamine-N-Oxide Response in Healthy Men

Clara E. Cho, Niklas D. J. Aardema, Madison L. Bunnell, Deanna P. Larson, Sheryl S. Aguilar, Janet R. Bergeson, Olga V. Malysheva, Marie A. Caudill, Michael Lefevre

Nutrients (2020), 12(8), 2220. DOI: 10.3390/nu12082220; PMID: 32722424.

A controlled study in healthy men compared equal amounts of choline supplied as choline bitartrate and phosphatidylcholine. Free choline increased TMAO substantially, while phosphatidylcholine did not differ from the control in this respect. The study shows that different choline sources can be metabolized differently.

FAQ / Sunflower Lecithin

Good questions. Clear answers.

Talk to us ↗

Is lecithin only a food emulsifier?

No. Its phospholipids have both water-attracting and lipid-attracting parts. This explains their usefulness as emulsifiers and their ability to form membrane structures. Lecithin is also a dietary source of several phospholipid classes.

Does 200 mg of phosphatidylcholine mean 200 mg of choline?

No. Choline makes up only part of the phosphatidylcholine molecule. Each capsule provides 200 mg of phosphatidylcholine; a separate choline amount is not stated. Do not compare those milligrams directly with choline salts or alpha-GPC.

Why choose sunflower instead of soy lecithin?

The active lecithin ingredient comes from non-GMO sunflower seeds. This identifies its source but does not, by itself, establish a soy-free manufacturing or cross-contact claim.

Does lecithin improve memory?

Clinical findings are mixed and do not support presenting ordinary lecithin as a quick memory booster. This formula is intended as a phospholipid supplement.

Why include olive and rosemary extracts?

Some fatty acids in phospholipids are susceptible to oxidation during storage. Olive and rosemary extracts help protect the lecithin mixture, serving a role in formula stability.

Does phosphatidylcholine raise TMAO?

The response depends on the choline form, amount, microbiome, and study conditions. Some controlled studies found a stronger TMAO rise with free choline than phosphatidylcholine. Results for one form should not automatically be applied to every phospholipid product.

Do the directions around alcohol mean the product protects against alcohol?

No. Lecithin and phosphatidylcholine do not neutralize alcohol or make drinking safer. Follow the label serving limits; the product's purpose is phospholipid supplementation.
