Some nutritional deficiencies are so widespread, thanks to soil depletion and reliance on processed foods, that just about everyone can benefit from supplementation. In this article, I will review 10 of the most popular nutritional supplements that may be helpful for many.

Ashwagandha

Ashwagandha is an adaptogenic herb, meaning it helps your body adapt to stress by balancing your immune system, metabolism and hormonal systems. The root contains the highest concentration of active ingredients that modulate hormones, including thyroid hormone, estrogen, progesterone and testosterone.

Naturally occurring steroids called withanolides in ashwagandha also suppress pathways responsible for several inflammation-based illnesses such as arthritis, asthma, hypertension, osteoporosis and cancer.

Ashwagandha also supports sexual and reproductive health in both men and women. In men, it helps boost testosterone levels, and has been shown to improve semen quality in infertile men.

In women, ashwagandha's ability to rebalance hormones (including thyroid hormone, estrogen and progesterone) has been shown to improve polycystic ovary syndrome and relieve menopausal symptoms.

Ashwagandha also has natural pain reliever (analgesic) and rejuvenating properties, and can promote general health when used regularly. While some adaptogens are stimulants in disguise, this is not the case with ashwagandha. It can give your morning exercise routine a boost, and when taken prior to bed it can help you get a good night's sleep as well.
