The sun, salmon, tuna, milk, cereal, pork, eggs, and mushrooms are all great sources of vitamin-D, but most Americans are deficient in it. How do you know if you’re one of them?
Muscle weakness is a sign you may be lacking vitamin D. If you don’t have the same stamina you had a few years ago, check your “D” level.
Women lacking in vitamin D are twice as likely to suffer depression, according to the journal of clinical endocrinology,
Insufficient levels of Vitamin D have also been linked to chronic pain, especially in
African-Americans. It also plays a role in heart health. When you don’t get enough, your blood pressure can creep up.
A study in the Journal of Clinical Sleep Medicine reported lower levels of vitamin D were also linked to higher levels of daytime sleepiness.
If you suffer from these signs, see a doctor because the solution may be in a simple supplement.
