Alpha Lipoic Acid (ALA) is a compound that most Health Care Professionals would agree is one that should be a core supplement on most people’s lists, however few in the general public know about it.
It is certainly a compound that would be found in most nutrition oriented clinics: and justifiably so given the spectrum of health benefits it provides.
A recent news release suggests that we can add to the list of ALA’s many benefits the stimulation of telomerase activity (in an animal model at this point).
Here is a quick summary of previously identified benefits provided by ALA (summarized from an article which appeared in the Life Extension Foundation Magazine):
- Reverses mitochondrial aging and decay
- Reduces oxidative stress in the body via powerful antioxidant activity
- Improves several components of the metabolic syndrome—a combination of risk factors that increases one’s risk for diabetes
- Reduces blood pressure
- Reduces insulin resistance
- Improves the lipid profile
- Reduces weight
- Increases insulin sensitivity
- Improves diabetic neuropathy
- Protects against cataract formation
- Improves visual function in glaucoma
- Helps prevents retinal cell death when combined with vitamin E in retinitis pigmentosa
- Reduces brain damage after a stroke
- Prevents bone loss, possibly through an anti-inflammatory effect1
- Removes toxic metals from the body
- Reduces frequency and intensity of migraines
- Improves skin texture
- Cells with mitochondria isolated from old animals degenerate far more rapidly than those with mitochondria from young animals
- When supplied with a nutrient regimen that includes lipoic acid, a profound regenerative effect is observed
- Experimental models show that lipoic acid optimizes function of the mitochondria in aging cells and reverses cell aging
- Recent data reveal that lipoic acid specifically targets factors that contribute to mitochondrial aging, dysfunction, and cell death.
- Lipoic acid can help to prevent cardiovascular disease, obesity, insulin resistance, and diabetic complications.
- Lipoic acid protects against nerve and brain cell damage induced by aging and trauma.
- New evidence suggests that lipoic acid may also have important cancer-preventive effects, even against some of the most difficult-to-treat malignancies.
Alpha Lipoic Acid is a supplement that many of us here at Biotics consume on a daily basis, and I am sure that many of you that read this newsletter do also, and continuing new published research documenting newly discovered health benefits of ALA justify this choice.
Here is the article from Emory Health Sciences
Alpha-lipoic acid stimulates telomerase in vascular smooth muscle
In human cells, shortened telomeres, the protective caps at the ends of chromosomes, are both a sign of aging and contribute to it. Scientists at Emory University School of Medicine have found that the dietary supplement alpha lipoic acid (ALA) can stimulate telomerase, the enzyme that lengthens telomeres, with positive effects in a mouse model of atherosclerosis.
The discovery highlights a potential avenue for the treatment for chronic diseases.
The results were published Thursday, August 20 in Cell Reports.
“Alpha-lipoic acid has an essential role in mitochondria, the energy-generating elements of the cell,” says senior author Wayne Alexander, MD, PhD, professor of medicine at Emory University School of Medicine. “It is widely available and has been called a ‘natural antioxidant’. Yet ALA’s effects in human clinical studies have been a mixed bag.”
ALA appears to exert its effects against atherosclerosis by spurring the smooth muscle cells that surround blood vessels to make PGC1 (peroxisome proliferator-activated receptor gamma co-activator 1)-alpha. PGC1-alpha was already well known to scientists as controlling several aspects of how skeletal muscles respond to exercise. While the Emory researchers did not directly assess the effects of exercise in their experiments, their findings provide molecular clues to how exercise might slow the effects of aging or chronic disease in some cell types.
“The effects of chronic diseases such as atherosclerosis and diabetes on blood vessels can be traced back to telomere shortening,” Alexander says. “This means that treatments that can restore healthy telomeres have great potential.”
“What’s new here is that we show that PGC1-alpha is regulating telomerase, and that has real beneficial effects on cellular stress in a mouse model of atherosclerosis,” says Shiqin Xiong, PhD, instructor in the division of cardiology and first author of the paper.
Xiong and Alexander used a model of atherosclerosis where mice lacked the ApoE cholesterol processing gene and were fed a high-fat diet. In this model, mice also lacking PGC1-alpha have more advanced plaques in their blood vessels, but only in older animals, the authors show.
Consistent with the poorer state of their blood vessels, aortic cells from PGC1-alpha-disrupted mice had shorter telomeres and reduced telomerase activity. Having shortened telomeres led the smooth muscle cells to display more oxidative stress and damage to the rest of their DNA.
The authors show that introducing PGC1-alpha back into vascular smooth muscle cells lacking that gene with a gene-therapy adenovirus could restore telomerase activity and lengthen the cells’ telomeres.
Telomerase is off in most healthy cell types and only becomes turned on when cells proliferate. Because telomerase is active in cancer cells and enables their continued growth, researchers have been concerned that stimulating telomerase in all cells might encourage cancer growth or have other adverse effects.
As a way to boost PGC1-alpha in cells more conveniently, Xiong and Alexander turned to alpha lipoic acid or ALA. ALA is a sulfur-containing fatty acid used to treat diabetic neuropathy in Germany, and has previously been shown to combat atherosclerosis in animal models.
Treating isolated smooth muscle cells with ALA for one day could both stimulate PGC1-alpha and telomerase, the authors found. ALA’s effects on vascular smooth muscle cells could also be seen when it was injected into mice. Xiong and Alexander say they are now investigating the effects of ALA on other tissues in mice. They have not observed increased cancers in ALA-treated mice, but say more thorough investigation is needed to fully assess cancer risk.
“While ALA is present in many foods and its effects in animal models look promising, it may be problematic for clinical use because of its poor solubility, stability and bioavailability,” Xiong says. “We are designing new ways to formulate and deliver ALA-related compounds to resolve these issues.”
