Lutein and Zeaxanthin Supplementation Improves Dynamic Visual and Cognitive Performance in Children: A Randomized, Double-Blind, Parallel, Placebo-Controlled Study.

Introduction: Supplementation with dietary neuro-pigments lutein (L) and zeaxanthin (Z) has been shown to improve many aspects of visual and cognitive function in adults. In this study, we tested whether a similar intervention could improve such outcomes in preadolescent children.

Methods: Sixty children (age range 5-12 years) were randomized in a 2:1 ratio in this double-blind, placebo-controlled clinical trial.

The Efficacy of the Novel Bioavailable Curcumin (Cureit) in the Management of Sarcopenia in Healthy Elderly Subjects: A Randomized, Placebo-Controlled, Double-Blind Clinical Study.

Sarcopenia represents the progressive loss of skeletal muscles, which occurs as a result of aging. Plant-derived phytochemicals have the potential ability to manage sarcopenial conditions. The randomized, placebo-controlled, double-blind clinical study involving thirty subjects evaluated the efficacy of Cureit™ supplementation in the management of sarcopenial conditions by measuring the variables, such as hand grip strength, weight lift strength, time/distance before feeling tired after cycling, walking and climbing stairs, and Karnofsky performance scale index along with effects on general fitness, such as protein, urea, oxidative stress, and hematology parameters.

A randomized, double-blind, placebo-controlled pilot study to evaluate the efficacy and tolerability of a novel oral bioadhesive formulation for the treatment of nonerosive reflux disease-related symptoms.

Objective: The use of antisecretory drugs can provide symptomatic relief in 70-80% of patients suffering from gastro-oesophageal reflux disease (GORD), although this benefit is reduced by 20-30% in the case of nonerosive reflux disease (NERD). The current study evaluates the efficacy and safety of a patented oral formulation (liquid sachets containing hyaluronic acid, a mixture of amino acids including proline, hydroxyl-proline and glutamine, and rice extract dispersed in a bioadhesive polymer matrix) for relieving the symptoms of NERD.

Methods: A single-centre, randomized, double-blind, parallel group, placebo-controlled clinical study was performed.

The Effects of Bioavailable Curcumin (Cureit) on Delayed Onset Muscle Soreness Induced By Eccentric Continuous Exercise: A Randomized, Placebo-Controlled, Double-Blind Clinical Study.

Delayed onset muscle soreness (DOMS) is a multifactorial progression related to muscle pain, swelling, stiffness, tenderness, altered joint kinematics, muscle fiber disruption, decreased strength and power, and acute tissue damage. Curcumin, a natural phytonutrient, could manage DOMS induced by eccentric continuous exercise due to its wide range of biological activities. This study was a randomized, placebo-controlled, double-blind clinical study to assess the efficacy of Cureit™-a bioavailable form of curcumin that may decrease damage from inflammation and oxidative stress associated with severe muscle damage induced by continuous eccentric exercise.

A novel bioavailable hydrogenated curcuminoids formulation (CuroWhite™) improves symptoms and diagnostic indicators in rheumatoid arthritis patients - A randomized, double blind and placebo controlled study.

Rheumatoid arthritis (RA) is an inflammatory disease that cause chronic pain, disability and joint destruction. The present placebo controlled randomized study aimed to evaluate the efficacy of a novel hydrogenated curcuminoid formulation-CuroWhite™, in rheumatoid arthritis (RA) patients. Twenty four RA patients were randomized in 1:1:1 ratio to receive 250 mg, 500 mg CuroWhite or placebo as one capsule a day, over a period of three months.

Development of Validated Methods and Quantification of Curcuminoids and Curcumin Metabolites and Their Pharmacokinetic Study of Oral Administration of Complete Natural Turmeric Formulation (Cureit™) in Human Plasma via UPLC/ESI-Q-TOF-MS Spectrometry.

Specific and sensitive ultra-high performance liquid chromatography-quadrupole time of flight-mass spectroscopy (UPLC-QTOF-MS) methods have been developed for the determination of curcuminoids and curcumin metabolites in human blood plasma. The UPLC-QTOF-MS method used a binary solvent delivery system and the chromatographic separation was performed on a C-18 (2.1 × 50 mm; 1.

Comparative Bioavailability of Two Diosmin Formulations after Oral Administration to Healthy Volunteers.

Diosmin is a flavonoid commonly found in citrus fruits, largely used as adjuvant treatment for circulatory disorders, including chronic venous insufficiency (CVI) and hemorrhoids. Following oral administration, diosmin is not directly absorbed but must first be hydrolyzed into its aglycone, diosmetin, which is then absorbed into the systemic circulation. The aim of the current cross-over clinical study was to assess the pharmacokinetic profile of µSmin Plus, a micronized diosmin flavonoid complex standardized in diosmin and formulated with a buffering agent (tested formulation).

Oral toxicity study of sports nutritional powder in Wistar rats: A 90 day repeated dose study.

Fitnox is a newly developed dietary ingredient for physical endurance composed of the extracts of leaf (45-50%), (black ginger) root (15-20%) and peel (25-30%). The aim of this study was to assess the subchronic oral toxicity of Fitnox (test substance) - in Wistar albino rats. Forty rats equally divided into 4 groups (control male, control female, treatment male and treatment female) administrated the test substance at 1000 mg/kg per rat daily for 90 days.

A Novel Highly Bioavailable Curcumin Formulation Improves Symptoms and Diagnostic Indicators in Rheumatoid Arthritis Patients: A Randomized, Double-Blind, Placebo-Controlled, Two-Dose, Three-Arm, and Parallel-Group Study.

Rheumatoid arthritis (RA) is an autoimmune, chronic systemic inflammatory disorder. The long-term use of currently available drugs for the treatment of RA has many potential side effects. Natural phytonutrients may serve as alternative strategies for the safe and effective treatment of RA, and curcuminoids have been used in Ayurvedic medicine for the treatment of inflammatory conditions for centuries.

A Randomized Single Dose Parallel Study on Enhancement of Nitric Oxide in Serum and Saliva with the Use of Natural Sports Supplement in Healthy Adults.

Sports supplements that stimulate the production of nitric oxide (NO) are widely promoted agents in the sports nutrition domain, and nitric oxide plays an important role to enhance the cardiovascular and physical fitness of the sports participants. The purpose of the study is to investigate whether oral intake of a sports nutritional supplement (Fitnox) is able to increase nitrate (NO) and nitrite (NO) levels in blood serum and saliva of healthy adults. Fitnox is a unique blend of Kaempferia parviflora methoxy flavones, pomegranate peel polyphenols, and Moringa oleifera leaf saponins.
