Liquid Vitamin D3

Maintaining healthy levels of vitamin D helps preserve youthful cognitive function and offers broad-spectrum benefits for bone, immune system health and more. Here's why you should be making sure you get enough of this essential vitamin every day:

Cognitive health

Vitamin D is important for maintaining cognitive health and function as you age. Healthy serum vitamin D levels have been shown to correspond with better scores on cognitive health tests and better maintenance of cognitive ability in aging individuals.^1-4

Bone and immune health

Vitamin D (along with vitamin K and essential minerals) is essential for facilitating the transport of calcium into the bone matrix.⁵ This is an important step in maintaining strong, healthy bones and teeth. Vitamin D also plays a critical role in healthy immune function.^5,6

Heart health & blood pressure support

Vitamin D helps to regulate the body's calcium balance while facilitating calcium absorption into the bloodstream, promotes a healthy inflammatory response in the cardiovascular system and encourages healthy endothelial function.^7,8 Vitamin D may also help inhibit excess renin levels. Healthy renin levels help maintain healthy blood pressure already within the normal range.⁹

Getting enough vitamin D

This vitamin D3 supplement delivers 50 mcg (2,000 IU) of vitamin D3 as cholecalciferol per liquid drop. We suggest that you take a 25-hydroxy vitamin D blood test after 3 months to assess and adjust your dosage. Your optimal blood levels should be 50–80 ng/ml year-round.
