Active-D is your convenient source of highly absorbable, liquid Vitamin D with added K2.
Vitamin D has a widespread effect on the human body. Vitamin D is important for optimal cardiovascular, neuromuscular and immune function and can be a factor in many symptoms people suffer from on a daily basis such as fatigue and general aches and pains.
Studies have shown that people with a Vitamin D level below 30 nmol/l have decreased strength and muscle wasting. One of the reasons for reduced muscle function is because people with deficient levels of Vitamin D are likely to have fatty muscles. In a recently published cross-sectional study, 59% of young women aged 16-22 in California (one of the sunniest states in the U.S.) had insufficient (< 29 ng/ml) levels of Vitamin D and 24% were deficient (< 20 ng/ml). Fat infiltration in muscle tissue affects strength and power and can impair physical functioning.1
Additional studies suggest that higher intake of vitamin D is associated with the reduced risk of certain cancers.2
People who have a high risk for deficiency include:
Those with limited sun exposure (most people in winter months)
People indoors most of the day
Dark skin individuals
Active-D contains the unique combination of Vitamin D and K-2. Studies have shown a slower progression of calcification in tissue for those taking both vitamin K2 and vitamin D together verse those just taking Vitamin D. The combination appears to protect against cardiovascular calcification. K2 appears to also help direct calcium to your skeleton, therefore preventing it from being deposited where you don't want it, such as your organs, joint spaces and arteries.
Deficiency of Vitamin D is becoming a well known epidemic due to the lack of daily sun exposure on a daily basis. It is estimated that millions of Americans currently suffer from Vitamin D deficiency.
Technically not a "vitamin," vitamin D is in a class by itself. Its metabolic product, calcitrol, targets over 2000 genes (about 10% of the human genome) in the human body. Current research has implicated vitamin D deficiency as a major factor in the pathology of at least 17 varieties of cancer as well as heart disease, stroke, hypertension, autoimmune diseases, diabetes, depression, chronic pain, osteoarthritis, osteoporosis, muscle weakness, muscle wasting, birth defects, periodontal disease, and more.*
Vitamin D's influence on key biological functions vital to one's health and well-being mandates that vitamin D no longer be ignored by the healthcare industry nor by individuals striving to achieve and maintain a greater state of health.*
How To Get Enough Vitamin D
There are 3 ways for adults to insure adequate levels of vitamin D:
1. Regularly receive midday sun exposure in the late spring, summer, and early fall, exposing as much of the skin as possible.
2. Regularly use a sunbed (avoiding sunburn) during the colder months.
3. Take 5,000 IU per day for three months, then obtain a 25-hydroxyvitamin D test. Adjust your dosage so that blood levels are between 50–80 ng/mL (or 125–200 nM/L) year-round.
