Nutritional supplement usage is commonplace, with millions of people taking one every day. Yet, back in 1955, when the Douglas Laboratories story began, supplements were not part of the mainstream. Sam Lioon, company founder, was a nutritional pioneer. He saw an opportunity to help individuals improve their health, and began selling nutritional supplements directly to healthcare professionals. From that humble beginning, Douglas Laboratories has grown into a globally recognized leader in the development and manufacturing of innovative, science-based nutritional supplements, designed to help healthcare practitioners who are focused on the healthy aging and active lifestyles of their clients.

Douglas DIM Enhanced 30 VCaps
Regular price $52.99 Save $-52.99/

Douglas DIM Enhanced is a microencapsulated form of diindolylmethane (DIM) designed to promote healthy estrogen balance. Standardized curcumin and green tea extracts are also included alongside wasabia.
Healthy hormone detoxification is a crucial part of the normal functioning of organs, including the breast. DIM is known to help stimulate natural detoxification enzymes and support healthy estrogen metabolism. As a natural component derived from indole-3-carbinole and cruciferous vegetables, DIM has been shown in clinical research to favour the production of the estrogen metabolite 2-hydroxyestrone over the more deleterious 16-hydroxyestrone. DIM can also decrease the severity and duration of recurrent breast pain and promote antioxidant support. Microencapsulated DIM by BioResponse is a patented, absorption-enhancing formulation to ensure proper assimilation by the body. It is the only DIM with proven absorption and activity demonstrated in independently performed clinical studies.
Polyphenols in green tea, specifically the catechins, provide the primary health promoting benefits associated with green tea consumption. Catechins, most notably epigallocatechin gallate (EGCG), are effective antioxidants and decrease harmful oxidative damage. Studies have shown that curcuminoids, naturally occurring bioactive compounds from turmeric, also scavenge free radicals by providing antioxidants. Since curcumin exhibits poor absorption when consumed orally, DIMÂ Enhanced contains a highly bioavailable curcumin that has up to a 20-fold improvement in bioavailability versus the standard 95% curcumin extracts.
Wasabia japonica (a member of the cruciferous vegetable family) contains long chain isothiocyanates (ITCs), which are unique to wasabia.

Douglas Estro-Mend 120 VCaps
Regular price $59.99 Save $-59.99/

Douglas Estro-Mend is a soy-free blend of herbs used in herbal medicine that helps ease nervous tension while relieving pain associated with menstruation and symptoms associated with menopause.
A complex interaction of hormones regulates menstruation. Imbalances of hormones, including estrogen, can result in menstrual pain and premenstrual symptoms, which often include changes in mood, energy, attention, appetite, sleep, physical comfort (breast tenderness, bloating) and quality of life. Phytoestrogens, including black cohosh, mimic the functions of estrogens without proliferative actions and help relieve menstrual pain and premenstrual symptoms. Significantly less estrogen is produced in the period before menopause. Hormonal fluctuations during this time can result in common menopausal symptoms, including hot flushes and vaginal dryness. Phytoestrogens also support and minimize the changes and symptoms that are sometimes experienced during menopause. Studies have found that black cohosh helps relieve menopausal symptoms, such as hot flushes, excessive sweating, insomnia, and vaginal atrophy. As menopause may result in sleep disruption, Estro-Mend also contains hops, which can relieve nervousness and aid sleep.

Douglas Prenatal 60Caps
Regular price $27.99 Save $-27.99/

Prenatal provides a variety of essential vitamins and minerals to ensure adequate intake for both mother and child. This balanced prenatal formula is provided in easy to swallow vegetarian capsules and promotes maternal and fetal health during pregnancy and lactation. Prenatal contains Metafolin, a patented and natural form of L-methylfolate (5- MTHF). L-methylfolate is the naturally occurring, predominant form of folate commonly found in cells. It is essential for a developing fetus, and helps to reduce the risk of neural tube defects when taken daily prior to becoming pregnant and during early pregnancy. Unlike synthetic folic acid, L-methylfolate can be used directly by the body, without the need for an additional enzymatic conversion. In certain populations, the body's ability to enzymatically convert folic acid to 5-MTHF may be compromised due to genetic differences. Metafolin contains only the S isomer of 5-MTHF and is the only form of folate that can cross the blood-brain barrier. Prenatal also contains important vitamins and minerals that help support energy production, antioxidant defence, skin and healthy glucose metabolism, as well as immune, muscle and thyroid gland function.
• Helps to reduce the risk of neural tube defects when taken daily at least three months prior to becoming pregnant and during early pregnancy

Douglas Ferro-C 60 Tabs
Regular price $21.99 Save $-21.99/

Ferro-C tablets provide 27mg of carbonyl iron that is easily absorbed. It also contains key nutrients important for iron absorption while supporting the formation and proper function of red blood cells. In the human body, iron is present in all cells and has several vital functions mediated through red blood cells _ as a carrier of oxygen to the tissues from the lungs in the form of hemoglobin (Hb), as a facilitator of oxygen use and storage in the muscles as myoglobin, as a transport medium for electrons within the cells in the form of cytochromes, and as an integral part of enzyme reactions in various tissues. Low iron can interfere with these vital functions.
Both vitamin C and E provide antioxidants to protect against oxidative damage. The B vitamins act as coenzymes and are essential components in most major metabolic reactions, including energy metabolism.
