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).
Thiamin, vitamin B1, works in the form of a co-enzyme (enzyme helper) in reactions that produce energy in our bodies. It helps break down glucose (a simple sugar) for energy in 2 steps of metabolism; helps make DNA and RNA and produce energy-rich molecules that power protein synthesis.
