Can Vitamin D Help Your Blood Pressure?

This Nutrient does so much for your heart, blood pressure! 

Wellness experts tout Vitamin D in the prevention of disease for optimum wellness.  Vitamin D affects 2,000+ genes in your body, and so many parts of your body!  Deficiencies in this important nutrient do affect your circulatory system and blood pressure.

“People with vitamin D deficiency have vascular dysfunction comparable to those with diabetes or hypertension1.”

“Sunshine Vitamin” D is a fat-soluble hormone present in few foods; some fish, fish liver oils, eggs, fortified dairy, and grains. Ultraviolet rays from sunlight striking the skin trigger vitamin D synthesis; vitamin D is produced by the body in response.

Symptoms of Low D:

  • Fatigue
  • Muscle pain/weakness/cramps
  • Joint pain
  • Chronic pain
  • Weight gain
  • High blood pressure
  • Restless sleep
  • More

Vitamin D helps lower blood pressure in people with and without hypertension.

Researching vitamin D in helping to lower blood pressure in people who don’t have hypertension, one large study2 found that people with more vitamin D had lower blood pressures and a lower risk of developing hypertension.

Studies look at the effect of vitamin D on blood pressure in people who have hypertension. One found that taking a vitamin D supplement lowered systolic blood pressure but not diastolic blood pressure6.

The farther you live from the equator, the higher your risk of developing high blood pressure, and blood pressure is typically higher in winter months than in summer!

Sunlight affects blood pressure by:

  • Causing your body to produce vitamin D. Lack of sunlight reduces vitamin D stores and increases parathyroid hormones, increasing blood pressure.
  • Being a negative inhibitor of your body’s renin-angiotensin system (RAS), which regulates blood pressure. If you’re vitamin D deficient, it can cause inappropriate activation of your RAS, which may lead to hypertension.
  • Exposure to UV rays causes release of endorphins, chemicals that produce feelings of euphoria and pain relief, naturally relieving stress.  Stress management is an important factor in resolving hypertension.

Get vitamin D!  Expose your bare skin to sunlight (ultraviolet B rays). This happens quickly, particularly in summer. Don’t tan or burn; expose your skin for half the time it takes to turn pink or burn. How much vitamin D is produced from sunlight depends on time of day, where you live, and skin color. The more skin you expose the more vitamin D is produced.

It’s hard to get Vitamin D from the sun in winter, or if you live in the north, work inside in cities with tall buildings.

How Much?  

Get tested!  Supplement with 5,000 – 10,000/mg D3 with calcium K2 for absorption per day.  Test after 3 months.

  • Deficient < 25 ng/ml
  • Optimal is 50-70 ng/ml
  • Therapeutic levels 70-100 ng/ml for disease
  • Excessive > 100 ng/ml
