Niacinate

DESCRIPTION:
Niacinate tablets, provided by Douglas Laboratories, contain inositol hexaniacinate which provides niacin. This ester of niacin and inositol eliminates the uncomfortable skin-flushing side effects often observed with high-dose crystalline niacin.
FUNCTIONS:
Niacin (vitamin B3) occurs in the body as two metabolically active coenzymes, NAD (nicotinamide adenine dinucleotide) and NADP (NAD phosphate).
The niacin coenzymes NAD and NADP have pervasive roles in energy-related and biosynthetic metabolic processes. At least 200 enzymes depend on these niacin cofactors. The NAD-dependent enzymes are involved in mostly catabolic, oxidative reactions that release energy from carbohydrate, fat, and protein, whereas the NADP-dependent enzymes more commonly function in biosynthesis of such compounds as fatty acids and steroid hormones.
Independent of its functions as NAD or NADP, niacin is also involved in the regulation of normal blood lipoprotein and cholesterol levels, and the maintenance of normal vascular tone.
Dietary niacin is generally well absorbed and taken up by the liver. Any excess niacin is metabolized by the liver and excreted by the kidneys.
Because the liver has a limited capacity to metabolize niacin, high doses of regular, crystalline niacin are often not well tolerated, causing vasodilatory side effects known as skin-flushing and itching.
INDICATIONS:
Niacinate tablets may be a useful dietary supplement for individuals who wish to increase their intake of niacin without the uncomfortable side effects of skin flushing.
SUGGESTED USE:One to three tablets daily with meals, or as directed by a healthcare professional.
SIDE EFFECTS:
No adverse side effects have been reported.
STORAGE:
Store in a cool, dry place, away from direct light. Keep out of reach of children.

Sublingual tabs
Scored tablet containing 5 mg of Pregnenolone for hormonal support. Allow tablet to dissolve in mouth or swallow as desired.
Pregnenolone is a natural hormone produced in the body from cholesterol. Pregnenolone has been linked with positive support of the immune system, mood and memory.
Pregnenolone is a chemical found in the body that is involved in the production of hormones. It does so by working as a predecessor during hormone synthesis. Some of these hormones experience a decreased production pattern as we age so supplementing this helpful chemical might make for a healthy choice.
There is some indication that pregnenolone might also help with various areas of nervous system support. The central nervous system holds high levels of pregnenolone which may reflect the importance of maintaining healthy levels. Pregnenolone may also reduce the effects of stress and fatigue. Therefore Douglas Labs' Pregnenolone Tabs may help support areas of hormone production and nervous system health.
Douglas Labs' Pregnenolone Tabs provide 5 mg of pregnenolone in each bisected sublingual tablet. These are designed with your convenience in mind and they are easily dissolved under the tongue.

Quercetin-Bromelain Complex
$39.99
$39.99
$39.99
QUERCETIN BROMELAIN Quercetin-Bromelain Complex, provided by Douglas Laboratories, is a unique formulation of quercetin, buffered vitamin C, and bromelain. Quercetin is a bioflavonoid that has excellent antioxidant activity. Magnesium ascorbate is a buffered form of vitamin C, a key antioxidant, which synergistically supports the quercetin activity. Bromelain is a proteolytic enzyme purified from pineapple, which is active and stable at the acidic levels found in the stomach.
FUNCTIONS Quercetin is a naturally occurring bioflavonoid with strong antioxidant activity. The antioxidant activity of quercetin protects the gastrointestinal tract in several ways. First, quercetin prevents oxidation of lipids. The gastrointestinal tract has an increased exposure to oxidative stress due in part to the lowered pH. It is important to protect the lipid bilayer of the cell wall of the gastrointestinal tract because these cells serve as an important part of the body's immune system. Secondly, quercetin prevents the depletion of glutathione from the cells of the intestinal tract. Glutathione is a cosubstrate for antioxidant enzymes glutathione peroxidase and glutathione reductase. By preserving the level of glutathione, quercetin protects metabolic activity and cellular structure of the highly vulnerable cells of gastrointestinal tract from toxic free radical damage. Vitamin C synergistically improves the ability of the quercetin to preserve glutathione. Thirdly, 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. The reduced contact provides protection from gastric lesions. Quercetin provides an antispasmodic activity that prevents the uncontrolled peristaltic activity found in diarrhea. The reduced excretion of the intestinal contents provides benefit to the gastrointestinal tract by preventing the constant production of cellular protective materials. Quercetin also reduces the immune response to allergens. Quercetin inhibits the IgE-mediated allergic mediator release from mast cells as well as IgG-mediated histamine release. Quercetin is a potent inhibitor of the lipoxygenase that metabolizes arachidonic acid, which is the first step towards proinflammatory arachidonic acid metabolites. Thus, quercetin with the assistance of vitamin C in the gastrointestinal tract helps protect against gastric lesions that permit highly antigenic proteins, antigenic compounds and/or infective agents from passing into the body. In addition it prevents the release of components of the allergic inflammation response. Bromelain is a supportive nutrient in helping prevent allergens from crossing the gastrointestinal tract. Bromelain assists in the breakdown of large macromolecular protein complexes. This reduces the chance that these complexes will leave the stomach untouched or in large fractions retaining their recognizable antigenic form that could pass through these gastric lesions inducing an allergenic response. Quercetin, vitamin C and bromelain are all dietary nutrients that help support the immune system. They inhibit the absorption of substances into the body that may induce the allergic response. In addition quercetin is used by the body to help reduce the allergic immune response in the intestinal tract, possibly providing nutritional support to normal inflammation processes. INDICATIONS Quercetin-Bromelain Complex may be taken as a dietary supplement for those individuals who wish to increase their intake of this important bioflavonoid, key antioxidant vitamin C, and the proteolytic enzyme Bromelain. SUGGESTED USE Two to four tablets twice daily between meals as a dietary supplement, or as directed by physician.

Vitamin D contains 125 mcg (5,000 IU) of vitamin D3 per tablet.
Vitamin D, also known as the “sunshine vitamin” is an essential vitamin that plays many important roles in the proper functioning of the body. Though classified as a vitamin, vitamin D is actually a key regulatory hormone for calcium and bone metabolism. Adequate vitamin D status is essential for ensuring normal calciumabsorption and maintenance of healthy plasma calcium levels. Besides bone support, vitamin D has many other roles in the body, including modulation of cell growth, neuromuscular and immune function
