Aloe Vera

Many claims are made for the health benefits of aloe vera, used both topically and orally. The scientific evidence is lacking. This home remedy may be soothing on the skin, but scientific claims don’t stand up to scrutiny. I had heard of aloe vera. I’ve seen it grown in flowerpots in the home and broken

Vital Stem: Affordable Stem Cell Treatments for Everyone? Anti-Aging Breakthrough?

Vital Stem is a dietary supplement mixture that supposedly reverses the changes of normal aging by increasing the body’s production of stem cells. We can’t know if it works, because it hasn’t been tested. Is Vital Stem a Miracle Anti-Aging Remedy? Evidence is lacking. Stem cell treatments are very promising. Bone marrow transplants are already

Anti-Aging Claims: The Fountain of Youth is Still Only a Legend

The Spanish explorer Ponce de León wasn’t really looking for the Fountain of Youth when he trekked through Florida. That’s only a legend that wasn’t attached to his name until after his death. The idea of anti-aging remedies dates back to at least 3500 BCE, and the hope is alive and well today. Who wouldn’t

Product B: Here We Go Again

“Telomeres shorten each time a cell divides. In most cells, the telomeres eventually reach a critical length when the cells stop proliferating and become senescent.

Antioxidants? It’s a Bit More Complicated

Like Pavlov’s dogs, I’m becoming conditioned to flinch when I hear the word “antioxidant” because it is so often followed by oversimplifications, distortions, and partial truths. The hype is everywhere, in magazines, on the Internet, on the radio, in books, in stores. Antioxidants promise to prevent heart disease, cancer,

Testosterone: Not an Anti-Aging Panacea

On the car radio, I have several times happened upon “infomercial” programs touting the benefits of testosterone replacement therapy for men, broadcast by doctors who specialize in prescribing the drugs. They have lots of wonderful stories about men who feel younger, happier, and more vigorous because of their macho remedies. It’s a tribute to the

Life Extension: Science or Pipe Dream?

Wouldn’t it be great if we could find a way to prolong our lives and to keep us healthy right up to the end? Ponce de León never found that Fountain of Youth, but science is still looking. What are the chances science will succeed? How’s it doing so far? In his new book The

Bioidentical Hormones: Estrogen is Good. No, It’s Bad. No, It’s Good

MENOPAUSAL WOMEN USED TO HAVE NO ESCAPE from the sufferings of the dreaded “Change.” In the mid-20th century, they were offered a reprieve. They could take a pill to replace their missing hormones, and feel back to normal. That was good in itself, but then they found that replacing estrogens could prevent osteoporosis and hip
