Not all vitamin D supplements are created equal, and new research suggests that one popular form may have an unexpected downside. Scientists found that taking vitamin D2 can actually lower the body's levels of vitamin D3, the form naturally produced ...
A vitamin D analog may help break down pancreatic cancer’s protective defenses, potentially making tumors more vulnerable to chemotherapy and immune attack. A small clinical trial found encouraging responses, especially in patients whose tumors ...
Weak sunlight can still damage skin DNA if you spend enough time outdoors, according to a landmark Australian study. Even UV doses too low to cause visible redness triggered cellular damage that could accumulate over time and contribute to skin ...
Scientists discovered a population of cells that can start the process of programmed cell death, survive it, and then help rapidly rebuild damaged tissue. Their descendants become far more resistant to future damage, revealing a mechanism that could ...
Low vitamin D levels may make recovery from breast cancer surgery more painful, according to a study of 184 women undergoing mastectomy. Patients with vitamin D deficiency were three times more likely to experience moderate to severe pain during the ...
An experimental compound called AP503 significantly strengthened bones in mice by activating GPR133, a receptor that boosts bone formation while slowing bone loss. Because the same treatment has also been linked to stronger muscles, researchers see ...
Researchers have produced a form of Spirulina containing biologically active vitamin B12 at levels comparable to beef. By carefully controlling the light used to grow the algae, they overcame a major problem with conventional Spirulina, which mainly ...
The belief that huge doses of vitamin C can ward off colds was popularized more than 50 years ago by Nobel Prize winner Linus Pauling. Since then, larger studies have found that vitamin C does not prevent most people from catching a cold, although ...
Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none. The preliminary findings suggest vitamin D could be worth studying ...
A large study of more than 5,500 adults over 50 found a striking combination of risk factors: abdominal obesity paired with vitamin D deficiency was linked to a 123% higher risk of death over six ...
A daily glass of 100% fruit juice or a smoothie may help improve more than just fruit intake. In a small four-week trial, participants who added one to a healthier diet showed significantly lower depression scores, hinting that a simple dietary ...
Linus Pauling was widely mocked for claiming that vitamin C could fight cancer, especially after trials using vitamin C pills showed no benefit. Researchers now know that intravenous vitamin C reaches vastly higher concentrations and can behave more ...
