Ultra Preventive® X is Douglas Laboratories’ signature formula and the most comprehensive multivitamin and
mineral supplement, with an organic fruit, vegetable and phytonutrient blend. This unique formula provides
antioxidant support and many beneficial nutrients, including carotenoids, flavonoids, polyphenols and
bioavailable forms of vitamins and minerals that contribute to optimal health.†

Ultra Preventive® X has been carefully developed to contain adequate amounts of vitamins, minerals, and
other beneficial nutrients and enzymes. Each ingredient is selected in consideration of its absorbability,
competitive relationship with other nutrients, allergenic potential, and long-term safety. The specific nutrients
are included in high-potency amounts because of the vital roles they play in antioxidant protection, cellular
health, energy, methylation, the nervous system, and vascular, bone, heart and immune support, among other

Alpha-lipoic acid is a nutritional coenzyme that is involved in energy metabolism of proteins, carbohydrates and
fats, has physiological functions for healthy blood glucose metabolism, and is able to scavenge a number of
free radicals. Besides being a universal free radical scavenger, alpha-lipoic acid can also recharge other
antioxidant systems such as glutathione and vitamins C and E.† Vitamin C is a potent water-soluble
antioxidant nutrient, also protecting cells from oxygen free radical damage. It is essential for connective tissue
and bone metabolism, capillary health, and immune function.† Vitamin C works together with vitamin E. Betacarotene supports vitamin E, recognized as the body’s most valuable fat soluble antioxidant. It prevents
oxidation of unsaturated fatty acids by inactivating free radicals, thus stabilizing and protecting cell
membranes, e.g., in the lungs, eyes, and arteries.†

The carotenoids lutein and zeaxanthin are important antioxidants in the macula of the eye, as evidenced by
recent studies performed by the NIH National Eye Institute. Research has shown that these important
carotenoids are the predominant pigments found in the macula to support healthy vision.†

The antioxidant activity of quercetin supports the gastrointestinal tract and immune system.† Quercetin
increases mucus secretion from gastric cells. The mucus polysaccharide provides a protective buffer for the
gastric cells from the low pH of the stomach contents. Quercetin also supports the normal immune response to
antigens.† Quercetin inhibits the IgE-mediated release from mast cells as well as IgG-mediated histamine
release. Many bioflavonoids, especially rutin and quercetin, support the health of the body’s circulatory system by helping maintain capillary blood flow and proper vascular permeability, integrity, and resiliency.†

N-Acetyl-l-Cysteine is a precursor for the sulfur amino acid cysteine, which is used by the body to synthesize
glutathione. Glutathione is a naturally occurring tripeptide that is a major component of two enzymes:
glutathione peroxidase and glutathione reductase, which help scavenge toxic free radicals and inhibit

Calcium and magnesium are included in a 1:1 ratio in bioavailable amino acid chelate and citrate forms to
support bone and tissue health.† Vitamin D is responsible for the absorption of calcium into the blood, and
Vitamin K2 deposits the blood calcium into bones and teeth. Therefore, consuming sufficient amounts of
dietary calcium is not enough for bone and cardiovascular health; the body needs to distribute and utilize the
calcium properly with aid of Vitamin K2.†

A significant dose of elemental choline from choline bitartrate is supplied in this formula. Choline acts as a
methyl donor for homocysteine and folate metabolism in the methylation cycle following conversion to betaine,
and also as a structural component of cellular membranes and synthesis of the neurotransmitter
acetylcholine.† Choline and inositol are lipotropic factors that support liver function and mobilize fats and bile.†

This formula contains methylated B vitamins for increased bioavailability to the body. Hydroxycobalamin is a precursor form of vitamin B12 converted in the body to both methylcobalamin and adenosylcobalamin. While
methylcobalamin is found in the cytosol of cells and predominates in blood and other fluids,
adenosylcobalamin is the major form of vitamin B12 stored in the mitochondria of cellular tissues.
L-methylfolate 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, L-methylfolate can be used directly by the body, without the need
for an additional conversion via the enzyme (5, 10 methylenetetrahydrofolate reductase (MTHFR)).

Ultra Preventive® X includes a specialized blend of organic phytonutrients. Chlorella and spirulina are
microalgae that supply chlorophyll, carotenes, B-vitamins, and trace elements. Organic fruits and vegetables in powder form provide naturally occurring nutrients and antioxidants to help fight free radical damage and support cellular health.† Green tea with EGCG and grape seed extract provide polyphenol antioxidants for vascular support.† Enzymes such as betaine HCL, papain and bromelain aid in the digestion of foods.†




Adults take 8 tablets daily with food or as directed by a healthcare professional. This product is best taken with meals in divided doses, such as 4 tablets with 2 largest meals of the day

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.) 

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.
