In short, yes.  Children under 5, pregnant women, those with malabsorption conditions (IBS, Crohn’s, colitis, coeliac disease), those who suffer from autoimmune conditions, people who are overweight and those on a plant-based diet are more likely to have insufficient levels.  As you grow older, your skin’s ability to make vitamin D starts to drastically decline, so the elderly are also at higher risk of vitamin D deficiency. Darker skin has a much higher level of melanin, the brown pigment which functions to filter and protect the skin from UV rays. The darker your skin, the more efficiently you block out UV rays decreasing your skin’s ability to make your own supply of vitamin D.  Supplementing with Beam & Balance Vitamin D + K2 Spray gives you a plentiful daily dose of vitamin D3, supporting those with a risk of deficiency.
