Lycopene lowered inflammation and improved blood flow

Blood vessels have an inner lining called the endothelium which may become inflamed, stiffened, and more likely to form clots. In this study, 126 healthy men, average age 34 with healthy weight, took 6 mg of lycopene or 15 mg of lycopene per day, or a placebo. After eight weeks, compared to the start of the study, while there were no significant changes in the low-dose or placebo groups, men who took 15 mg of lycopene had much higher antioxidant levels, less DNA damage, better blood pressure flow and lower systolic blood pressure, lower levels of C-reactive protein–an inflammatory factor–and an increase in the size of LDL-cholesterol particles, making them less likely to stick to artery walls and form plaque.

In discussing their findings, doctors said supplementing to raise lycopene levels in the blood can reduce oxidative stress and improve the health and function of the endothelium blood vessel linings.

Vitamin D improves reproductive health

Doctors said when animals are deficient in vitamin D, sperm counts and sperm motility are low. In this study, researchers measured vitamin D levels in 40 men and found that those with 75 nanomoles of vitamin D per liter of blood (nmol/L) had much higher sperm motility compare to men with 25 nmol/L or less. Motility is the ability of sperm to move properly toward the egg. As levels of vitamin D increased, more of the sperm were motile, and had normal structure, shape, and size.
