Chewable Vitamin K and D Supplement with DHA/EPA

anabolic laboratories ultra k2-d3 chewable vitamin d

Price: $22.00

  • Provides healthy dose of Vitamin D3
  • Vitamin D3 is the small molecule required by the gut for calcium ingestion and regulates the bloodstream level of calcium
  • Provides Vitamin K2, also known as menaquinone-7, menaquinone-9 and menaquinone-4, which are the small molecules required for modification of proteins which deposit calcium in bones
  • Contains DHA and EPA for additional health support

Brief Product Description

Ultra K2-D3 provides the recommended amount of vitamins K2 and a liberal amount of vitamin D3, the preferred form of vitamin D. These vitamins are specific for calcium metabolism, bone health and density retention. Research has recently shown the majority of North Americans are deficient in these vitamins, especially during dark winter months, and thought to be indirectly responsible for a portion of adult bone breakage. As a pleasant tasting, chewable tablet, Ultra K2-D3 is easily taken by people who find it difficult to swallow supplements and need vitamins K2 and D3.

Ultra K2-D3 - How it Works


Osteoporosis is the underlying cause for breakage of the large supporting bones in humans, especially post-menopausal women and seniors of both sexes. Accidental falls are often morbid and can become mortal. The onset of osteoporosis is now considered direct indicator of overall health. Osteoporosis is a syndrome in which the bone micro-architecture is disrupted, the minerals calcium and magnesium are lost and the amount and variety of non-collagenous proteins in bone are also altered. The measured rate of Bone Mineral Density (BMD) loss has now become a hi-tech predictor of death for both men and women from all causes1.

For many people osteoporosis is directly related to long-term, insufficient dietary intake of calcium, magnesium, vitamin D3 and K2 – in other words nutrient starvation. This dire condition may be due to the decreased appetite of the elderly, decreasing ability to absorb important nutrients with age, lack of sunshine and exercise, substitution of regular meals with non-nutritious snacks, the lack of will power to follow a healthy diet and/or the final phases of chronic alcoholism2. It appears the requirement for vitamin K2 also increases with age; bloodstream markers of vitamin K2 deficiency increase with age despite similarities in diet and a steady ingestion of dietary K23. Correlating with these findings, vitamin K2 deficiency is becoming common in the US as we age. Unfortunately, vitamin K2 is not a common nutrient supplied from fruits and vegetables but is only available in small amounts from meats, fish and eggs. A major source for vitamin K2 in Asia, not suffering osteoporosis at the US rate, is fermented legumes such as soybeans - not a common dietary source in the US. Purified, natural vitamin K2 has recently become available; encouraging a number of recent clinical investigations.

Long-term supplementation of post-menopausal Japanese women with vitamin K2, in combination with vitamin D3, resulted in increased vertebral bone mass without any increase in possible adverse effects such as blood coagulation4. These encouraging results have been confirmed by several studies in Europe which have even shown that BMD is sometimes increased with vitamin K2 supplementation. X-ray scans of the femoral necks of women taking vitamin K2 for three years evidenced that actual bone strength, as well as bone density increased with time, as judged by this important indicator5. Vitamin K2 has also been shown safe for adult women at the level of several mg/day for several years.

The diets of many US adults are also deficient in vitamin D3 because the richest source of this nutrient is fortified milk and our intake drops after the teen years. At the same time, wide-spread D3 deficiency of North Americans has risen because people are scared and they now avoid sunshine and the outdoors. The majority of Americans, of all ethnic backgrounds, are now seriously deficient in vitamin D3, especially during winter, and this deficiency increases with age6. Likewise, calcium intake decreases with advancing age except for those taking supplements, drinking milk and eating plenty of red meats. Calcium and vitamin D supplementation has been shown to increase BMD in the femoral neck and spine and to coincidently reduce the incidence of nonvertebral fractures7. Concerns over the safety of vitamin D3 supplementation have been raised but are not well-founded; only persons ingesting more than 40,000 IU per day have been reported suffering vitamin D3 toxicity. People enjoying the sun need not worry about vitamin D3 toxicity because the biosynthesis is tightly controlled and shuts down after a short time under the sun8.

Suggested Usage - Ultra K2-D3

Suggested Usage: As a dietary supplement, take 1 tablet daily, with or between meals, or as directed by a physician.


Product should not be taken if on blood thinning medications



• Seniors are more prone to falls and bone breakage than younger adults and many breaks are the result of low Bone Mineral Density (BMD)

• Reduced BMD is most often caused by insufficient calcium, magnesium, vitamins K2 and D3 which is traced to poor diets

• Dietary supplementation with vitamins K2, D3 and especially a combination of K2 and D3 has been shown to benefit BMD

• Vitamin K2 and vitamin D3, taken together as a dietary supplementation prevention program may reduce the incidence of bone fractures

• The forms of vitamin K2 in ULTRA K2-D3 have long bloodstream half-lives which allows convenient, once-daily supplementation

• Overdoses of vitamins K2 or D3 are extremely rare

The Need To Consider Quality:

Of the magnesium supplements tested by ConsumerLab.com, 25% failed to meet quality standards. One magnesium supplement contained only 45.4% of labeled amount, despite boasting a "GMP" (Good Manufacturing Practices) seal on its label, and another supplement provided only 28.8% of the labeled amount.

Tests by ConsumerLab.com have found multivitamins that were short on ingredients, failed to dissolve properly, or were contaminated with heavy metals.
ConsumerLab.com, New Product Review: Multivitamin and Multimineral Supplements, Posted 4/1/09

The Food and Drug Administration (FDA) has found that manufacturing problems have been associated with dietary supplements. Products been recalled because of microbiological, pesticide, and heavy metal contamination, and because they do not contain the dietary ingredients they are represented to contain, or they contain more or less than the amount of dietary ingredient claimed on the label.
