Urolithin A: The Game-Changing Nutrient for Healthy Aging

When a team of scientists from EPFL, the Swiss Federal Institute of Technology in Lausanne, set out to thoroughly study the health benefits of pomegranates, they discovered something truly remarkable – the power of a postbiotic nutrient, Urolithin A (UA) to promote cellular health and longevity. For the past 15 years, Urolithin A has been one of the most well-researched longevity molecules. Over 300 studies, 11 of which are clinical trials, show impressive benefits in UA’s ability to target some of the key biological hallmarks of aging. These same scientists and doctors developed the first and only clinically tested Urolithin A formulation (more on that below!)

How the OS-01 Peptide Works to Reverse Skin’s Biological Age

When we’re young, building a skin care routine is relatively simple: a face wash, moisturizer and sunscreen will do the trick. But as we grow older and develop visible signs of aging skin, choosing from the overwhelming array of mature skin care products like anti-aging creams, serums, and treatments often feels like an impossible task. What can we trust to actually work? It’s easy to get lost in new trends like 10-step skincare routines, but try to look past marketing and prioritize your skin’s health above all else. As our largest organ and first line of defense against environmental aggressors, our skin can have an enormous impact on our overall body health. A truly effective skin care routine should support your skin’s health first and improve the way it looks as a result. That’s where OneSkin comes in.

Estrogen + Microbiome = Estrobolome

The function of the digestive tract is essential for proper function of almost every biological system in the body. Hormone metabolism and endocrinology is no exception to this rule. In fact, the connection is so strong with estrogen, that there is a term to describe it in the literature – the estrobolome.

Going Beyond Cholesterol Testing to Enhance Heart Health

Cardiovascular conditions are one of the most common disorders of modern times. Testing for cholesterol as a potential modifiable risk factor for heart disease is a common part of many functional medicine providers’ clinical practices. Recently, at Rupa Health we wrote about the latest innovations in cholesterol testing such as measuring ApoB-containing lipoproteins and genetic differences in intracellular cholesterol production or gut absorption. In this article we will go beyond cholesterol to discuss the other critical tests for heart health.
