Vitamin B6, also referred as pyridoxine, is one of the vitamins included in the B-complex vitamin family. This vitamin helps the human body to produce the neurotransmitters norepinephrine (which helps the body cope with stress) and serotonin (which regulates mood).
Pyridoxine is also helpful in maintaining the level of hormones in the human body, that helps to control many different activities and metabolic occurrences in the body. Also, it is required for proper brain function and development for people of all ages.

100 of this tuber contains 598mg of potassium which is about 17 percent of the recommended daily intake.
Copper is a trace mineral found in all body tissues and is required for survival. For instance, copper plays an important role in maintaining a healthy immune system and nerve cells, and producing red blood cells.
The body also uses this essential trace mineral in the manufacture of numerous enzymes, some of which act as antioxidants. In addition, it plays an essential role in maintaining the health of the myelin sheath (a fatty white substance which surrounds the axon of some nerve cells) as well as it is important for keeping hair from thinning and turning. A person who has a copper deficiency can experience the following symptoms:
- birth defects;
- thyroid disorders;
- low skin pigmentation;

100 of this tuber contains 5,2 mg of vitamin C which is about 9 percent of the recommended daily intake.
Vitamin B1, also referred as thiamine, is a vitamin which belongs to the vitamin B complex. It is a coenzyme used by the human body to maintain proper heart and nerve function and to metabolize food for energy.
