For most of us, vitamins are synonymous with good health. Yet most Americans do not take vitamins. (See Research Update along side this article.) Changing diet affects the need for vitamins, as does age, since older bodies don’t absorb vitamins as well as younger ones. Vitamin D is a good example of the controversy surrounding vitamins.
Structurally, the difference between the acetyl-L-carnitine (ALC) and L-carnitine (LC) is that ALC is an LC molecule that also contains an attached acetic acid group. This structural difference is small, but it produces a considerable difference in the biochemical properties of the molecule and, consequently, in its effects on metabolism.
Juvenon Health Journal Volume 2 Number 4 – April 2003 Wishful thinkers are often ingenious in their ability to rationalize the avoidance of exercise. Some worry whether too much exercise would wear them out prematurely. Others question whether an older body really needs to break into a sweat. Recent discoveries, combined with a widely accepted theory of aging, clearly counter these rationalizations and document how exercise initiates a coordinated series of responses by the cells of the body culminating in greater strength, energy and stamina. The mitochondrial theory of aging is widely accepted. It states that cumulative damage to the mitochondria, the power plants in each cell, contributes to physical decline, a wide variety of degenerative conditions, and ultimately to cell death. Maintaining mitochondrial health is therefore essential to successful aging. This is where exercise comes in. Here’s how it works. More Mitochondria Without The Hard Work? Recent research with animals has demonstrated that it is possible, at least with some cells, to artificially increase the production of mitochondria without exercise. The authors demonstrated that they could increase the production of mitochondria by introducing a gene to overproduce one of the key regulators of mitochondrial biogenesis, known as CaMK. This research may …
What are mitochondria, what are their functions and why are they so important? These tiny cellular structures specialize in energy production, but also play a role in aging, cancer, cell death, and degenerative diseases. Virtually all the energy needed for you to go about your daily life ultimately derives from the mitochondria.
