Douglas Laboratories is proud to announce that Ultra Preventive X now contains Metafolin, a patented, natural form of (6S) 5-methyltetrahydrofolate (5-MTHF) as well as 1,000 IU of vitamin D3 per serving. 5-MTHF is the naturally occurring, predominant form of folate commonly found in cells and is essential for overall health, as it participates as a cofactor in a reaction that involves the remethylation of homocysteine to methionine. Unlike synthetic folic acid, 5-MTHF can be used directly by the body, without the need for an additional conversion via the enzyme (5,10-methylenetetrahydrofolate reductase (MTHFR)). In certain populations, the body's ability to convert folic acid to 5-MTHF by use of this enzyme may be compromised due to genetic differences. Metafolin contains only the S isomer of 5-MTHF and has been shown to be the only form of folate to be able to cross the blood-brain barrier. Additional vitamin D3 (also known as cholecalciferol) has been added to this formula as numerous scientists now feel that supplementation with vitamin D at levels greater than previously thought necessary is critical to helping maintain overall health.


Studies show that a high percentage of adults in North America and other developed areas eat less than the minimum daily allowance of 10 or more essential nutrients. Adequate amounts and proper balance of these nutrients are needed not only for maintaining good health, but also for the dietary management of the body's structure as well as the optimum functioning of its various systems, including the immune and gastrointestinal systems.

Ultra Preventive X has been carefully developed to contain the right proportions of vitamins, minerals, trace elements, and other nutrients without danger of toxic build-up or other side effects. Each ingredient is selected in consideration of its absorbability, competitive relationship with other nutrients, allergenic potential, and long-term safety. Certain nutrients such as beta-carotene, vitamin C, vitamin E, and B-complex vitamins are included in high-potency amounts because of the vital roles they play in antioxidant protection, energy production, the maintenance of healthy blood cells, the nervous system, hormonal balance, and more. Minerals and trace elements are provided in their safest and most bioavailable forms.

Ultra Preventive X's herbal green food base also includes important phytonutrients. Gluten-free grasses and several varieties of microalgae supply chlorophyll, carotenes, B-vitamins, and trace elements. Cruciferous vegetables, broccoli and cauliflower, offer protective sulforophane compounds known for their ability to induce protective phase 2 detoxifying enzymes.



Adults take 4 tablets daily or as directed by a healthcare professional.

When taking a multivitamin, remember to adjust the amount of individual supplements accordingly. (Example: If your multivitamin contains 15mg of zinc, you should reduce your zinc supplementation by that amount.) 

This product is best taken with meals in divided doses, such as 2 tablets with 2 largest meals of the day.
Store in a cool, dry place, away from direct light. Keep out of reach of children.

California Proposition 65 & Dietary Supplements Warning


Consumption of most daily multivitamins (30-60mcg biotin) poses NO risk to lab results.  However, daily consumption of 5mg Biotin or more (greater than 160 fold of the 30 mcg daily recommended intake) may cause inaccurate results in many immunoassays.  These include, but are not limited to, thyroid function tests, cardiac and tumor markers, serology tests and serum allergy IgE tests.
Although high doses of biotin may interfere with laboratory tests, biotin is quickly cleared from the body in most cases.  For patients taking 5mg of biotin daily, blood level of biotin will return to within normal limits for laboratory testing within 3.5 hours of intake.  
Biotin (Vitamin B7) is commonly found in over-the-counter multi-vitamins and supplements for hair, nails and skin improvement.
Laboratories recommend that supplements containing more than 5mg biotin should not be taken 8 hours prior to any lab tests.  Click here to see the list of lab tests that can potentially be affected by Biotin consumption.
