Douglas Laboratories is proud to announce that Ultra Preventive III 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.


DR. Adrian's Suggested Use: 1 - 2 tabs daily for 4 - 5 days. NOTE: Ultra Preventative III 180 Tabs offer double the amount per Serving of ingredients compared to Ultra Preventative Caps because Tabs are concentrated. If you prefer to take fewer pills the Tabs maybe a good choice. However, Caps are better absorbed.

Douglas Labs Suggested Use: Adults take 6 tablets daily with meals or as directed by a healthcare professional.


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.
