ADEK supplies the four fat-soluble vitamins A, D3, E, and K2 to support immune function, bone building, and cardiovascular health.* ADEK is part of any immune support protocol, boosting the body’s defense against viruses and raising antioxidant status.* ADEK is designed for optimal absorption to meet the needs of people who eat a low-fat or low-quality diet.*  It is well suited for gallbladder, liver, pancreatic, or related gastrointestinal concerns.*


ADEK features all the fat vitamins A, D3, E, and K2. Each vital for health on their own, the vitamins A, D, E, and K work together to optimize human health. These four vitamins interact synergistically to support immunity, build strong bones and teeth, and protect the blood vessels against calcification that leads to heart disease.*

Synergistic & Individual Benefits
All four fat-soluble vitamins make independent contributions to immune function, yet studies show that they work better in the cooperation of the others. Every cell in the body has a vitamin D receptor. But, vitamin D receptors only become “active” in the presence of vitamin A. Meanwhile, vitamin K is necessary for the synthesis of vitamin D-made proteins that build bone. And all four fat-soluble vitamins work as antioxidants so that inflammatory markers don’t get out of control and damage cells.

On an individual basis there are many clinical benefits of vitamins A, D, E, and K:

Vitamin A
Vitamin A supports vision and eye health. It also builds immunity and raises your antibody levels to fight off viruses. Low vitamin A can occur in people who avoid animal products or who eat low-quality diets. Getting enough vitamin A has been shown to:

  • Improve Skin*: Vitamin A helps with skin repair and wound healing. Acne is associated with low vitamin A and treatment may reduce breakouts.
  • Support Immune Function*: Vitamin A enhances immune cell activity and maintains the body’s physical barriers against pathogens.
  • Support Fertility*: Vitamin A is necessary for reproductive function in both men and women. It also plays a role in growth and development in fetuses.


Vitamin D
Vitamin D is the “sunshine vitamin” because our bodies synthesize vitamin D in response to sunlight. Due to limited sun exposure, many people don’t get enough vitamin D, putting them at risk of osteoporosis and poor health. Raising vitamin D levels has been shown to:

  • Prevent Bone Disorders*: When vitamin D is low, bone breakdown occurs to satisfy the body’s demand for calcium. Maintaining healthy vitamin D helps prevent osteoporosis and osteopenia.
  • Prevent Muscle Weakness & Decrease Falls*: Vitamin D supports strong muscle contractions and helps reduce fall risk in all populations, including athletes and the elderly.
  • Support Immune Function*: Vitamin D improves the number and function of immune cells that fight off disease.
  • Support Cardiovascular Health*: Adequate vitamin D decreases calcification of the arteries, reducing stress on the heart.


Vitamin E
Vitamin E is best known as an antioxidant that protects skin from damage due to the sun or aging. Poor immune function is a symptom of vitamin E deficiency and studies show vitamin E confers improved resistance to infection in people with poor health. Getting enough vitamin E has been shown to:

  • Prevent Bone Disorders*: Vitamin E reduces oxidative stress that damages joint tissue, leading to pain and osteoarthritis.
  • Support Immune Action*: Vitamin E raises immune cells and improves resistance to infection in people with poor health. It also enhances the antibody response to vaccination in older adults.
  • Support Metabolic Health*: Vitamin E modulates the chronic inflammation that results from insulin resistance. Supplementation may help control diabetes complications.


Vitamin K
Vitamin K is named for the Danish word “koagulation” for its blood clotting abilities. It helps regulate calcium levels, making it important for bone strength and preventing calcium buildup in the arteries. Low vitamin K can result from a diet low in animal products and green vegetables. Vitamin K insufficiency is more common in those with gastrointestinal disorders, chronic illness, or following a round of antibiotics. Getting enough vitamin K has been shown to:

  • Support Bone Health*: Vitamin K2 activates the bone-building protein osteocalcin to prevent bone loss.
  • Protect Cardiovascular Function*: Vitamin K2 reduces calcification of the arteries, helping to keep blood vessels healthy and flexible.
  • Improve Cancer Survival Rates*: Vitamin K has anti-inflammatory effects, inhibiting the cancer marker NF-Kappa-B that fuels tumor growth.


What Makes This Product Different?
ADEK features superior forms of vitamins A, D, E, and K that can be easily absorbed by the body. It also includes phosphatidylcholine, which helps the body breakdown and absorb fat.*

ADEK is designed for absorption even in GI-compromised individuals.*  ADEK supplies the active form of each fat-soluble vitamin so that the body can use them immediately without the need for activation via the liver*:

  • Vitamin A  is the preformed vitamin A palmitate, not the inactive beta carotene.
  • Vitamin D3 is the active cholecalciferol, not the inactive D2 ergocalciferol.
  • Vitamin E is from mixed tocopherols, including alpha tocopherols that is protective for humans.
  • Vitamin K2 is the Menaquinone-7 form, not the inactive vitamin K1 form.

Individuals with GI issues, celiac disease, gastric bypass, pancreatic insufficiency, hydrochloric acid insufficiency, or who have had gallbladder removal are at risk of fat-soluble vitamin deficiency.* You will benefit from a supplement specially designed to overcome these obstacles.*


Quick Facts

Who Can Benefit From Taking ADEK?
In the perfect world, you could get all your nutrition from food. However, surveys show that nearly half of the U.S. population does not meet the recommended levels for vitamin D, vitamin E, and vitamin K. Low levels of vitamin A are also common.

  • The reasons for these deficiencies vary: Modern farming may result in foods having fewer nutrients than in the past. Some individuals have poor ability to absorb nutrients, either due to compromised gut health or genetic differences. In the case of the fat-soluble vitamins, gall bladder removal, liver problems, or pancreatic insufficiency all get in the way of absorption.
  • Then there is stress: High levels of oxidative stress due to environmental toxins, chronic stress, alcohol, smoking, or intense exercise may increase your nutrient needs.
  • In the case of vitamin D, avoiding the sun leads to deficiency.  Living in cold climates also puts you at risk of vitamin D deficiency during the winter.
  • Groups with a particular risk for nutrient deficiencies who can benefit from ADEK include teenagers, athletes, the elderly, vegetarians, individuals on a restrictive diet, those who have a chronic disease, and individuals taking medications that cause nutrient deficiencies as a side effect.* ADEK can serve as dietary insurance for all of these populations.*
  • ADEK is also useful for people with osteopenia, joint pain, or other bone disorders.*
  • Vitamin A, D, E, and K are recommended with vitamin C as part of an immune support protocol.*

Who Should Not Take It?

  • Check with doctor if taking blood thinners, such as Warfarin. Vitamin K increases blood clotting and may impair the action of blood thinners.
  • Women who are pregnant or nursing should speak with a healthcare practitioner prior to supplementing.
  • Anyone with a serious medical condition or who uses medications should consult with a physician prior to supplementing.
