Q: I’m only 40, but I feel much older. What could be causing this, and what can I do about it?

Damage to cell membranes is what drives and accelerates the aging process. Every cell in the human body is surrounded by a membrane. Healthy membranes are vital for proper communication between and within cells. They enable nutrients to enter a cell and be used to efficiently generate energy, for waste to be removed, and for optimum function of the whole body.

Cell membranes endure assault from free radicals. As we get older, we naturally lose our ability to repair such damage, and today’s environmental toxins, stress, and poor diets do additional harm. However, we can help slow down aging and restore energy by repairing cell membranes.

Cell Membrane Starvation

Fatty substances, called lipids, are the building blocks of cell membranes. Imagine a smooth leather glove that fits perfectly on your hand. If it is continually exposed to harsh weather and toxic substances, that glove becomes scarred and brittle, and will easily tear or crack. An undernourished cell membrane shares a similar fate, and this speeds up the aging process.

The Nutritional Solution

One of the most promising supplements for repairing cellular damage is NT Factor. It’s a form of lipid replacement therapy, meaning it contains lipids in a form that can be absorbed directly into cell membranes, literally replacing damaged molecules with healthy ones.

When taking supplements with NT Factor, my patients report substantial improvement in energy levels, a feeling of well-being, improved ability to handle stress, better mental function, sleep, and digestion, and fewer colds and joint problems.

NT Factor: Study Snapshot

NT Factor is food based, contains no added sugar or stimulants, and doesn’t interact with drugs. But by improving health, it may reduce need for medications. These are some highlights from more than 20 published studies:

Among people diagnosed with moderate to severe fatigue, NT Factor in multivitamin, antioxidant, or anti-aging formulas has reduced fatigue by up to 43 percent within one to several weeks. And, in healthy, middle-aged people, a drink with NT Factor noticeably improved physical and mental energy within 15 minutes to three hours. —Functional Foods in Health and Disease

Among people suffering from chronic fatigue syndrome, fibromyalgia, Gulf War illness, or chronic Lyme disease for an average of at least 17 years, NT Factor reduced severely debilitating and previously unrelenting fatigue by 31 percent in 60 days. —International Journal of Clinical Medicine

How to Benefit

NT Factor is available as an ingredient in a few supplement products, including a multivitamin/mineral formula (Nutritional Therapeutics Propax with NT Factor) and an anti-aging formula (Nutritional Therapeutics Healthy Aging NT Factor). Common daily dosages for NT Factor range from 3,000 to 4,000 mg.
