What is Amaranth?

Amaranth is obtained from Amaranthus dubius, also called Red Spinach, Chinese Spinach, Yin choy, Hsien tsai, Hon-toi-moi, Araikeerai, Cheera, Chauli, Ptee, Terere or Telele. The plant originated in South America and was introduced to Asia, Africa and Europe. It is commonly used as a leafy vegetable in Southeast and South Asia and Africa. In traditional African medicine it is used as a herbal medicine.[1]

The edible portion of amaranth leaves can contains in 100 gm of leaf about 84 gm of Water, 176 kJ (42 kcal) of Energy, 8.3 gm of Carbohydrates, 4.6 gm of Proteins, 1.8 gm of Fibers, 0.2 gm of Fats, 410 mg of Calcium, 103 mg of Phosphorus, 8.9 mg of Iron, Vitamins such as 64 mg of Vitamin C, 1.2 mg of Niacin, 0.42 mg of Riboflavin, 5716 μg of β-Carotene and 0.05 mg of Thiamin, and Minerals such as Nitrates and Oxalates.[2, 3]

The protein content analysis of Amaranth leaves shows proteins such as Glutelin, Prolamin, Globulins, Albumin and other Amino Acids in Amaranth.[4]

What are the Benefits of Amaranth?

Amaranth is a rich source of Vitamin C, which can be beneficial for cardiovascular health. Vitamin C supplementation can decrease systolic and diastolic blood pressure in patients with mild hypertension.[5, 6] Vitamin C can reduce plaque buildup in healthy adults by preventing adherence of White Blood Cells (WBCs) to blood vessels in patients with low plasma Vitamin C.[7] Vitamin C can increase good cholesterol High Density Lipoprotein (HDL) in women.[5] Vitamin C can lower triglycerides, Low Density Lipoprotein (LDL), fasting blood glucose levels, serum insulin and HbA1C in patients with Type II diabetes.[8] Vitamin C is also known to boost the immune system and reduce the frequency of common cold.[9]

Vitamin C has antioxidant effects in smokers, cancer patients, and exercise induced oxidative stress. Vitamin C supplementation helps reduce the oxidative stress on skeletal muscles caused by exercise and attenuate the protein oxidation caused by exercise, thus resulting in reduced muscle soreness and improved muscle function.[10, 11, 12] Vitamin C can reduce plasma C Reactive Proteins (CRP) in smokers, and because CRPS can be involved in atherosclerosis, Vitamin C use can indirectly help reduce atherosclerosis in smokers.[13] Vitamin C and Vitamin E combination taken together by smokers can reduce oxidative stress induced DNA damage in the blood cells caused by smoking.[14] Vitamin C may lower the toxicity of chemotherapy drugs in esophageal cancer patients, in gastritis patients supplementation with Vitamin C reduces the risk of gastric cancer, and a combination of Vitamin C with molybdenum was found to be protective against esophageal cancer in a long term study.[15, 16]

Apart from the benefits of Vitamin C present in Amaranth, there are other additional benefits to taking Amaranth one of which is the rich protein content of the supplement, which can be a protein source for athletes.[2, 3, 4] Studies with Amaranth showed an increase in nitrate and nitrite levels post ingestion, which can be beneficial as an energy boost for athletes.[17, 18]

Why Take Amaranth Supplements?

Amaranth is a rich source of proteins, vitamins and minerals that can have cardio-protective, anticancer, immunity, energy boost, and other benefits.[2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 15, 16, 17, 18]

What are the Most Common Side Effects of Taking Amaranth Supplement?

Currently there are no known side effects of Amaranth.[19] In elderly men undergoing strength training high dose of Vitamin C and Vitamin E taken together can decrease the bone mineral density improvement from strength training.[20]

What are the Precautions and Warnings with Amaranth Use?

Pregnant women, nursing women, and individuals with hematologic disorders including thalassemia, anemia, cancer or glucose-6-phosphate deficiency should consult a physician before using supplements with Vitamin C.[21, 22, 23, 24] World Health Organization does not recommend use of Vitamin C supplementation during pregnancy.[24]. Patients taking Simvastatin and niacin should consult their physician and monitor their cholesterol levels when taking Vitamin C, since the HDL levels can increase with concurrent use of the three.[23]
