Calcium formate is a water-soluble salt of an essential mineral nutrient with potential for use as a dietary calcium supplement. Formate ion is a product of endogenous and xenobiotic metabolism, but sustained high plasma formate concentrations (such as occur in cases of methanol poisoning) are toxic to the retina and optic nerve. Humans and primates have reduced capacity for formate oxidation c...

Twenty-four juvenile leopard tortoises were divided into four groups of six; one group was fed a basic low-calcium feed for six months, and the other three groups were fed the same basic diet supplemented with one, three and nine times the amount of calcium recommended as a supplement to the diet of reptiles. The animals' bone mineral content and bone mineral density were estimated by dual ener...

Results: At the time of survey, 43% (n=548) reported using some form of supplement. Supplement use was significantly associated with gender (female) and chronic musculoskeletal ailments such as arthritis, osteoporosis and generalised back or neck problems. A diagnosis of hypertension or a heart condition were significant barriers to supplement use in this sample. The most common potential drug-...

When conducting research in the area of bone health, accurate measurement of calcium intake is crucial. The rapid assessment method (RAM) is one technique that has frequently been used for its measurement of calcium intake. However, the RAM and other currently established questionnaires lack the assessment of dietary supplement use, which is common for athletes. Our objective was to evaluate th...

Calcium is an essential nutrient required in substantial amounts, but many diets are deficient in calcium making supplementation necessary or desirable. The objective of this study was to compare the oral bioavailability of calcium from calcium formate, a new experimental dietary calcium supplement, to that of calcium citrate and calcium carbonate. In a four-way crossover study, either a placeb...

It has been estimated that under ordinary conditions from 5 to 10 per cent of all chicks hatched are weaklings that cannot be raised successfully to maturity and for this reason are destroyed by the intelligent poultryman. The cause of this condition has been attributed, 1, to a tendency of hens which have been laying heavily during the winter to lay eggs having weak germs the subsequent spring...

BACKGROUND Recent randomized data suggest that calcium supplements may be associated with increased risk of cardiovascular disease (CVD) events. Using a longitudinal cohort study, we assessed the association between calcium intake, from both foods and supplements, and atherosclerosis, as measured by coronary artery calcification (CAC). METHODS AND RESULTS We studied 5448 adults free of clinic...

Our objective in this study was to estimate calcium intakes from food, water, dietary supplements, and antacids for U.S. citizens aged >or=1 y using NHANES 2003-2006 data and the Dietary Reference Intake panel age groupings. Similar estimates were calculated for vitamin D intake from food and dietary supplements using NHANES 2005-2006. Diet was assessed with 2 24-h recalls; dietary supplement a...

OBJECTIVE To compare iron absorption of a prenatal multivitamin supplement containing both iron and calcium (HICA) to that of another multivitamin containing a lower iron dose and no calcium (LI). METHODS In a crossover study, serum iron was measured in 12 healthy women administered HICA and LI separately on 2 different occasions. Blood samples were taken at 0, 1, 2, 3, 4, 6, and 8 hours afte...
