In geometry, a tetrahedron (plural: tetrahedra or tetrahedrons) is a polyhedron composed of four triangular faces, three of which meet at each corner or vertex. It has six edges and four vertices. The tetrahedron is the simplest of all the ordinary convex polyhedra and the only one that has fewer than 5 faces. The tetrahedron is the three-dimensional case of the more general concept of a Euclidean simplex.
Research shows that B vitamins improve memory by creating a protective shield for the neurons in the brain. B vitamins break down homocysteine, which is an amino acid that is a toxic poison to nerve cells. These vitamins also aid in the production of red blood cells, which carry oxygen, an important brain nutrient. The most important B vitamins for memory include B6, B12, and Folic Acid (B9).
Vitamin B5, also called pantothenic acid, is one of 8 B vitamins. All B vitamins help the body convert food (carbohydrates) into fuel (glucose), which the body uses to produce energy. These B vitamins, often referred to as B complex vitamins, also help the body use fats and protein.
