Vitamin K helps your body make proteins needed for blood clotting and the building of strong bones.
One serving of NaturCress® provides 9% of the recommended daily value of Vitamin K while providing relief of heartburn and bloating without drugs or artificial ingredients.
Since most multi-vitamins don't provide 100% of the daily value of Vitamin K, NaturCress helps complete your minimum daily value.

Doctor Reviews NaturCress
"I take this product before my morning coffee and I don’t have any heartburn or acid response when I do." Dr. JKR
"NaturCress works! Love that it is all natural, drug free and free from allergens. I have been searching for a natural heartburn remedy and have found it. Works quickly too. I highly recommend it." ● Lorelei R., July 7, 2020.
"Vitamin K deficiency may impair the activity of VKDPs and increase the risk of osteoporosis and fractures."
Linus Pauling Institute » Micronutrient Information Center
Recommendation for Older adults (>50 years)
"Because older adults are at increased risk of osteoporosis and hip fracture, the above recommendation for a multivitamin/mineral supplement and at least one cup of dark green leafy vegetables daily is especially relevant."
Linus Pauling Institute Recommendation
"An inverse relationship between vitamin K intake and mortality was reported in a US national survey (NHANES III) of 3,401 participants (74). Adequate vs. inadequate vitamin K intakes (based on sex-specific AI: 90 μg/day for women and 120 μg/day for men) were associated with a 22% lower risk of cardiovascular disease (CVD)-related mortality and a 15% lower risk of all-cause mortality."
Linus Pauling Institute Finding
"Although allergic reaction is possible, there is no known toxicity associated with high doses (dietary or supplemental) of the phylloquinone (vitamin K1) or menaquinone (vitamin K2) forms of vitamin K (42)." Vitamin K Toxicity
