Safety and toxicological evaluation of AlgaeCal (AC), a novel plant-based calcium supplement.

The present study was conducted to examine the safety of a novel plant-based calcium supplement, derived from marine algae and containing high levels of calcium, magnesium, and other bone supporting minerals (commercially known as AlgaeCal (AC)). The present study evaluated the broad-spectrum safety of AC using a variety of toxicological assays including acute oral, acute dermal, primary skin irritation, and primary eye irritation toxicity. Under the conditions of the study, the acute oral LD(50) of AC was found to be greater than 5000 mg/kg body weight in rats, while the single acute dermal LD(50) was greater than 2000 mg/kg body weight.

Safety and toxicological evaluation of a novel chromium(III) dinicocysteinate complex.

Chromium(III) is an essential trace element required for normal protein, fat and carbohydrate metabolism. It also helps in energy production and increasing lean body mass. Chromium(III) dinicocysteinate (CDNC) is a unique form of bioavailable chromium(III).

Comparing metabolic effects of six different commercial trivalent chromium compounds.

Recent reports provide cogent evidence that the average individual becomes chromium deficient with age. Unfortunately, chromium deficiency is strongly associated with many aspects of the Metabolic Syndrome, including insulin resistance and type 2 diabetes. Since replacement of chromium, per os, often ameliorates many deleterious manifestations associated with insulin resistance and diabetes, it is not surprising that many different, commercial trivalent chromium compounds are available on the market.

Long-term safety evaluation of a novel oxygen-coordinated niacin-bound chromium (III) complex.

Chromium (III) is an essential micronutrient required for normal protein, fat and carbohydrate metabolism, as well as helps insulin metabolize fat, turn protein into muscle and convert sugar into energy. A broad spectrum of research investigations including in vitro, in vivo and clinical studies demonstrated the beneficial effects of novel oxygen- coordinated niacin-bound chromium (III) complex (NBC) in promoting glucose-insulin sensitivity, lipid profile, cardioprotective ability and lean body mass. This study examined the long-term safety of NBC by orally administering either 0 or 25 ppm or the human equivalency dose of 1000 microg elemental chromium (III) as NBC per day for 52 consecutive weeks to male and female Sprague-Dawley rats.

Berry anthocyanins as novel antioxidants in human health and disease prevention.

Edible berries, a potential source of natural anthocyanin antioxidants, have demonstrated a broad spectrum of biomedical functions. These include cardiovascular disorders, advancing age-induced oxidative stress, inflammatory responses, and diverse degenerative diseases. Berry anthocyanins also improve neuronal and cognitive brain functions, ocular health as well as protect genomic DNA integrity.

Cytokine expression due to Helicobacter pylori in a tissue culture model.

Helicobacter pylori, in recent years, has been recognized as the major causative agent in chronic gastritis and peptic ulcer disease in humans. H. pylori is a ubiquitous organism, with at least half of the world's population infected.

Enhanced cardiovascular function and energy level by a novel chromium (III)-supplement.

The impetus for the novel Energy Formula (EF) which combines the niacin-bound chromium (III) (0.45%) (NBC), standardized extract of Withania somnifera extracts (10.71%), caffeine (22.

Regulation of vascular responses to inflammation: inducible matrix metalloproteinase-3 expression in human microvascular endothelial cells is sensitive to antiinflammatory Boswellia.

Endothelial cells are critical elements in the pathophysiology of inflammation. Tumor necrosis factor (TNF) alpha potently induces inflammatory responses in endothelial cells. Recently we have examined the genetic basis of the antiinflammatory effects of Boswellia extract (BE) in a system of TNFalpha-induced gene expression in human microvascular endothelial cells (HMECs).

Safety and toxicological evaluation of a novel niacin-bound chromium (III) complex.

Chromium is an essential trace element required for normal protein, fat and carbohydrate metabolism. It also helps in energy production and increasing lean body mass. Niacin-bound chromium (NBC) is a unique form of bioavailable chromium that promotes healthy lipid profile.

Antimicrobial effects of antioxidants with and without clarithromycin on Helicobacter pylori.

Increasing resistance to currently used antimicrobials has resulted in the evaluation of other agents that have antimicrobial activity against Helicobacter pylori. H. pylori American Type Culture Collection (ATCC) strain 49503 (a toxin-producing strain known to be associated with gastric cancer) was grown, a cell suspension prepared in 2 mL PBS and diluted 10-fold.

Inhibition of Helicobacter pylori in vitro by various berry extracts, with enhanced susceptibility to clarithromycin.

The objective of this study was to evaluate the effects of various berry extracts, with and without clarithromycin on Helicobacter pylori. Resistance to clarithromycin by H. pylori has been reported, leading to interest in alternatives/adjuncts to therapy with clarithromycin.

Physico-chemical properties of a novel (-)-hydroxycitric acid extract and its effect on body weight, selected organ weights, hepatic lipid peroxidation and DNA fragmentation, hematology and clinical chemistry, and histopathological changes over a period of 90 days.

Garcinia cambogia-derived (-)-hydroxycitric acid (HCA) is a popular and natural supplement for weight management. HCA is a competitive inhibitor of the enzyme ATP citrate lyase, which catalyzes the conversion of citrate and coenzyme A to oxaloacetate and acetyl coenzyme A (acetyl CoA) in the cytosol. Acetyl CoA is used in the synthesis of fatty acids, cholesterol and triglycerides, and in the synthesis of acetylcholine in the central nervous system.

Dose- and time-dependent effects of a novel (-)-hydroxycitric acid extract on body weight, hepatic and testicular lipid peroxidation, DNA fragmentation and histopathological data over a period of 90 days.

(-)-Hydroxycitric acid (HCA), a natural extract from the dried fruit rind of Garcinia cambogia (family Guttiferae), is a popular supplement for weight management. The dried fruit rind has been used for centuries as a condiment in Southeastern Asia to make food more filling and satisfying. A significant number of studies highlight the efficacy of Super CitriMax (HCA-SX, a novel 60% calcium-potassium salt of HCA derived from Garcinia cambogia) in weight management.

Effects of niacin-bound chromium, Maitake mushroom fraction SX and (-)-hydroxycitric acid on the metabolic syndrome in aged diabetic Zucker fatty rats.

Previous studies in our laboratories have demonstrated that niacin-bound chromium (NBC), Maitake mushroom and (-)-hydroxycitric acid (HCA-SX) can ameliorate hypertension, dyslipidemias and diabetes mellitus, and therefore may be useful in weight management. In the present study, we used aged, diabetic Zucker fatty rats (ZFR) (70-75 weeks) in order to determine whether NBC, fraction SX of Maitake mushroom (MSX) and 60% (-)-hydroxycitric acid (HCA-SX) from Garcinia cambogia, alone or in combination, can affect certain aspects of the metabolic syndrome. Syndrome X or metabolic syndrome has been described as a concurrence of disturbed glucose and insulin metabolism, overweight and abdominal fat distribution, mild dyslipidemia, and hypertension, which are associated with subsequent development of type 2 diabetes mellitus and cardiovascular disease.

The bactericidal effects of Lactobacillus acidophilus, garcinol and Protykin compared to clarithromycin, on Helicobacter pylori.

Chronic infection with Helicobacter pylori causes peptic ulcers, gastric cancer and lymphoma. We evaluated the inhibitory effects of the probiotic Lactobacillus acidophilus DDS-1J, the antibiotic clarithromycin and the natural antioxidants garcinol and Protykin (containing 50% trans-resveratrol) on Helicobacter pylori strain ATCC 49503. The findings of this study indicate that Lactobacillus acidophilus DDS-1J exerts a growth inhibitory effect on H.
