Does soy lecithin act in the prevention of cardiovascular diseases?

The main benefit of soy lecithin is to reduce bad cholesterol (LDL). This is because soya lecithin acts as an emulsifier, dissolving the fatty plaques in veins and arteries.

Soy lecithin also helps reduce triglyceride levels. Another benefit is that soy lecithin is a source of fatty acids, so it helps increase levels of good cholesterol (HDL).

Is it true that soy lecithin helps the brain function well?

The main nutrient provided by soy lecithin is phosphatidylcholine, a substance that makes up the membrane of brain cells.

Recent scientific studies have demonstrated that soya lecithin is very beneficial for the recovery of brain nerve structure and the formation of acetylcholine, a neurotransmitter responsible for the retention of knowledge and prevention of age-related memory loss.

Some research indicates that the use of soy lecithin may prevent the onset or progression of neurodegenerative diseases such as Alzheimer’s disease, dementia, amnesia, among other diseases.

Soy lecithin acts as a protector of the liver, improves liver function and prevents the damage caused by the consumption of alcoholic beverages – it is recommended that the supplement be consumed in larger doses before and after the consumption of alcohol.

Besides, the supplement has a detox effect, as it stimulates the elimination of toxins by the liver. This benefit is very important for those who take many medications on a daily basis.

The supplement also contributes to improved digestion, as it breaks down the fat particles in the body, reducing the work of the digestive system.

Due to the indiscriminate cultivation of soybeans, we recommend buying a supplement extracted from organic soybeans, as the raw material is natural, healthy and sustainable.

Other components

Pay attention to the composition of the soy lecithin supplement. The ingredient in the highest concentration in the composition of the supplement is the first on the list and so on.

  • Vitamin E acts as an antioxidant, i.e. it neutralises free radicals and slows down premature skin ageing. It also acts as a vasodilator, helping to improve blood circulation and preventing cardiovascular diseases such as hypertension and atherosclerosis.

  • Omega 3 and 6 are fatty acids. Omega 3 helps strengthen the cardiovascular system, increases immunity and stimulates brain activity. Omega 6 regulates blood pressure, strengthens the immune system and acts on hormonal activity.
  • Vitamin C strengthens the immune system, acts as an antioxidant, protects the cardiovascular system against numerous diseases, reduces the risk of ophthalmological diseases, eliminates the risk of stroke, prevents the advance of tumours, stimulates the formation of collagen and promotes the absorption of nutrients.
