Answer: Perhaps, but it is good to know more about it first.

Lipoic acid is a naturally-occurring compound that is found in small amounts in food and is also synthesized in small amounts by humans. The amount of lipoic acid available in dietary supplements (200-600 mg) is likely as much as 1,000 times greater than the amount that could be obtained from the diet alone. Continue reading

online_survey_icon_or_logo1Public outreach is a vital part of the mission of the Linus Pauling Institute. Please help us improve our efforts by taking this short online survey.

It should only take about 5-10 minutes to complete. As a way to say thank-you, we’ll be doing a drawing among survey participants for 2 $50 Amazon gift cards as well as 10 copies of the following Linus Pauling Institute publications: An Evidence-based Approach to Vitamins and Minerals: Health Benefits and Intake Recommendations and An Evidence-based Approach to Phytochemicals and Other Dietary Factors. 

Thank you for your participation!

Adrian Gombart, PhD - Expert on Vitamin DAdrian Gombart, Ph.D., is the Linus Pauling Institute’s resident expert on vitamin D. The institute hosted a free webinar with him, discussing the role of vitamin D in bone health, cancer prevention, fighting infections, and supporting the immune system. We present it here, along with his follow-up answers to audience questions.

Nutrition’s legacy as a “soft science”

Nutrition has always been considered a “soft science”—a field rife with studies showing associations but no firm causation. Conclusive trials in humans are very difficult to do, and long-term studies assessing disease prevention are often cost prohibitive. In the past, the status quo was to do studies with laboratory animals to test whether a certain food or nutrient had an effect on cancer incidence or the hardening of arteries that can lead to heart disease or another such end point, but this approach lacked a critical element: the “why” was missing. “Something went in, something possibly resulted from it, but what happened in-between was largely a black box,” said Linus Pauling Institute Director and Distinguished Professor of Biochemistry and Biophysics Balz Frei, PhD. “What was lacking was mechanisms.”
