Douglas Laboratories Ultra Preventive X

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.*


  • Maintains good health*
  • Promotes healthy immune and gastrointestinal function*
  • Supports energy production, the maintenance of healthy blood cells, the nervous system, hormonal balance, and more.*


Ultra Preventive® X tablets may be a useful dietary supplement for those who wish to consume the essential nutrients for health.*

Suggested Use

After 2 to 4 months, dosage may be lowered back down to 2 capsules each day with food and may continue on that dosage as needed or as directed by your healthcare professional.*
