In KOH, the Mg(II)-bromopyrogallol red (BPR) complex produced a very sensitive polarographic wave at -1.30 V. The wave height was linear with the concentration of Mg(II) in the range of 0.05 to 2 microg/mL. The detection limit was 0.01 microg/mL. The electrochemical behavior of Mg(II)-BPR was studied by electrochemical and spectrophotometric methods. Experiments proved that the polarographic wave of Mg(II)-BPR was due to the reduction of BPR in the Mg(II)-BPR complex. The method, which was sensitive, selective, and simple to perform, was used to determine magnesium in foods, and the results were consistent with those obtained by atomic absorption spectroscopy.

Are there Effective Vegan-Friendly Supplements for Optimizing Health and Sports Performance? a Narrative Review.

Curr Nutr Rep

March 2025

Departamento de Investigación y Desarrollo, Good Research and Science (GRS), Avenida Ramón Picarte 780, 5090000, Valdivia, Chile.

Purpose Of Review: Veganism, characterized by the exclusion of all animal-derived products, has grown in popularity due to ethical, environmental, and health considerations. However, vegan athletes often face unique nutritional challenges related to dietary deficiencies of critical nutrients such as proteins, vitamin B12, iron, calcium, and omega-3 fatty acids, among others. This narrative review aims to explore the efficacy and benefits of vegan-friendly supplements specifically tailored to athletic performance, focusing on essential micronutrients, ergogenic aids, and nutrient bioavailability.

Purpose: In the current study we evaluated a blend of ingredients containing mulberry leaf extract (to lower postprandial glucose of the evening meal), tryptophan (facilitator of the sleep initiation) to benefit sleep initiation and quality in adults with self-reported difficulties with sleep initiation.

Methods: Forty-three adults aged between 25 and 50 years enrolled in a randomized, crossover, double-blind, controlled trial. Participants received standardized meals with a glycemic load of 55 ± 10% and were assigned to receive treatment comprising a combination of mulberry leaf extract (750 mg), whey protein containing 120 mg tryptophan, zinc (1.

Phosphorus (P) is vital for plant growth, but its agricultural use is limited by soil fixation and environmental loss. This study developed an organic ligand-responsive phosphate release system by hybridizing magnesium-iron-layered double hydroxides (Mg-Fe LDH) with pectin from apple and citrus (pectin-A/C). Structural properties and phosphate (PO) release of LDH hybrids with different concentrations of metal precursors (0.

Impact of the dietary antioxidant index on bone mineral density gain among mexican adults: a prospective study.

Arch Osteoporos

March 2025

Centro de Investigación en Políticas, Población y Salud (CIPPS), Facultad de Medicina, Universidad Nacional Autónoma de México (UNAM), 04510, Mexico City, Mexico.

Unlabelled: In the Mexican population, low dietary antioxidant intake (DAI) is associated with reduced bone mineral density (BMD). A decline in DAI over time further contributes to BMD loss, particularly at the total hip, femoral neck, and lumbar spine, with a more pronounced effect in women over 45 years old.

Purpose: Bone remodeling, balancing resorption and formation, is crucial for bone health.
