Can a daily scoop of collagen powder really improve your skin?

Published August 1, 2021

Manufacturers tout collagen supplements as a way to improve signs of skin aging and skin quality. There is some research that shows they may bring skin benefits, reducing wrinkles, speeding wound healing, and improving skin hydration and elasticity.

Vitamin D and the big C

Published July 1, 2021

New research has found an association between high and low levels of vitamin D and cancer risk. However, many older adults don’t get the recommended daily amount of 600 to 800 international units, as the main sources of vitamin D are sun exposure (which many people try to avoid) and certain foods, like fatty fish, fortified milk and cereal.

Other blood tests to consider include those for HIV or hepatitis C infection, and a test to measure fasting blood sugar.
