The Effects of B12, Lecithin and Garlic

Updated February 21, 2017

As science continues to create studies and trials to learn ways to prevent and eventually eliminate illnesses such as heart disease and cancer, it has become clear that certain vitamins and foods re-emerge as important to health. For example, garlic, used for thousands of years in medicine and food, has shown the ability to foster healing in scientific experiments. Lecithin, which is found in the cells of all living organisms, is believed to be important in breaking down food for energy. Supplementing with vitamin B12 may help improve conditions such as male infertility.

Vitamin B12

As with all B vitamins, vitamin B12, known also as cobalamin, helps the body convert carbohydrates into energy, metabolises protein and fats, and promotes healthy nerve cells. B12 also helps produce DNA and RNA and form red blood cells in the body. If you suffer from a deficiency of vitamin B12 you will experience numbness, tingling in your fingers and toes, shortness of breath, fatigue and nervousness. If you have chronic fatigue syndrome, vitamin B12 shots may benefit you. According to the University of Maryland Medical Center, you have a higher risk of breast cancer as a post-menopausal woman with low B12 amounts in your diet. Vegans, because they do not eat eggs or dairy, as well as the elderly and those with eating disorders, can also have a B12 deficiency. Taking B12 supplements may also help increase sperm counts and treat Parkinson's disease and chronic asthma. Since vitamin B12 works with folate it can help reduce the chances of developing breast cancer. You can get your daily requirements of vitamin B12 in your diet by eating animal protein and dairy products. Ask your doctor for the correct dosage of B12 supplements, which you can take as liquid drops, capsules, tablets, lozenges or softgels. While known as safe and non-toxic, vitamin B12 can be depleted if you are taking antibiotics, tetracycline, chemotherapy medications, anticonvulsants or H2 blockers to reduce stomach acid.


Lecithin, an important fatty substance found in cell membranes of plants and animals, breaks down fats. The liver produces lecithin naturally every day, which helps break down blood and dietary fats into small molecules and eventually into fatty acids for energy. Foods containing lecithin include peanuts, eggs, steak, beef liver, oranges, cauliflower and soybeans. You can also take lecithin in capsules safely without complications from other medications. Taking lecithin supplements also helps repair damage to the liver.


Garlic is part of the lily family and has been used as a spice and medicine for thousands of years, but it may also help prevent cancers, such as the colon and stomach varieties. In addition, garlic thins the blood and may slow hardening of the arteries, which can lead to stroke or heart disease. It is also said to help lower high blood pressure. A 2009 report by the Korea Food and Drug Administration in Seoul indicates that eating or taking garlic reduces the risk of cancers of the prostate, colon, ovaries, oesophagus, larynx and oral and renal cells. You can ingest garlic by eating it cooked or raw or by taking capsules, tablets or liquid extracts. Consult with your doctor before consuming garlic if you currently take blood-thinning medication.
