Found in cells throughout the brain and body, Vitamin D plays an integral role in regulating the neuromuscular and immune systems [1,2], as well as mood and sleep [3]. It’s also a critical hormone precursor that supports new cell growth [4] and bone formation [5,6].
Vitamin D is essential to maintaining health and optimizing performance. Unfortunately it’s only found in a few foods and often in very small amounts. Because of it’s vital importance and lack of dietary sources, humans evolved to be able to make Vitamin D on their own.
Ultraviolet (UV-B) radiation from sunlight penetrates uncovered skin and naturally gets converted into Vitamin D. Season, time / length of day, cloud cover, smog, sunscreen, and darkness of skin all affect the amount of UV exposure and rate of Vitamin D synthesis [7]. It’s been shown that cloud cover and pollution can reduce UV energy by up to 60%, and UV-B radiation doesn’t penetrate glass so exposure to sunlight through a window does not produce Vitamin D [8].
It’s estimated that 1 billion worldwide suffer from Vitamin D deficiency or insufficiency [9]. Symptoms of inadequate levels of Vitamin D include bone pain and muscle weakness, but the symptoms can be subtle and go undetected in the initial stages. Deficiency has been associated with increased risk of autoimmune, cardiovascular, and infectious diseases [10].
Natural Stacks™ Vitamin D3 provides the highly bioavailable form of natural Vitamin D (Cholecalciferol).
To ensure optimal absorption of this fat-soluble vitamin we suspended it in the healthiest fat on the planet - organic cold pressed coconut oil. The natural fatty acids in coconut oil aid the transport of Vitamin D into the bloodstream for fast and effective results.

PERFORMANCE ESSENTIAL
Suggested Use: Take 1 softgel per day, preferably in the morning, or as directed by a healthcare practitioner
Vitamin D3 (Cholecalciferol)
Each softgel features 5,000 IU of the most bioavailable form of natural Vitamin D (Cholecalciferol). Vitamin D3 is absolutely essential for optimal performance and health.
Organic Coconut Oil
Certified organic coconut oil is the perfect addition to Vitamin D3. Fat-soluble vitamin D is suspended within the coconut oil allowing for maximum absorption.
When studying the relationship between vitamin D levels and cognition, researchers found that “the high vitamin D group had significantly more correct responses than the low vitamin D group”. [1]
A meta-analysis of 18 independent randomized controlled trials (total 57,311 participants) found that “Intake of ordinary doses of vitamin D supplements seems to be associated with decreases in total mortality rates”. [2]
An extensive 2007 study on 2,160 healthy women concluded that “higher vitamin D concentrations are associated with longer LTL, which underscores the potentially beneficial effects of this hormone of aging and age-related diseases”. [3]
A rodent study investigating the neuroprotective effects of vitamin D discovered it’s ability to mitigate inflammation, making it “a useful therapeutic option to alleviate the effects of aging on cognitive function”. [4]
Dr. Rhonda Patrick recently discovered that “Vitamin D hormone regulates serotonin synthesis”. Serotonin is the neurotransmitter responsible for mood regulation. [5]
A study examining the cognitive performance, mood, and physical performance of 80 older adults found that “vitamin D deficiency was associated with low mood and with impairment on two of four measures of cognitive performance”. [6]
