Additional product info: A small study demonstrated a progressive and marked improvement of motor capacity in consecutively evaluated patients with sporadic Parkinson’s disease (PD) who started with below normal laboratory indexes of riboflavin and who eliminated red meat from their diets while receiving high multiple daily doses of riboflavin orally (30 mg every 8 h) over a period of 6 months while taking their usual symptomatic medications (2).

A randomized, double-blind, placebo-controlled trial was conducted to determine the effect of 1 year of vitamin E supplementation on respiratory tract infections in elderly nursing home residents. A total of 617 persons aged at least 65 years and who met the study’s eligibility criteria were enrolled and Vitamin E (200 IU) or placebo capsule were administered daily. Fewer participants receiving vitamin E acquired 1 or more respiratory tract infections or upper respiratory tract infections. When common colds were analyzed in a post hoc subgroup analysis, the vitamin E group had a lower incidence of common cold and fewer participants in the vitamin E group acquired 1 or more colds. Supplementation with 200 IU per day of vitamin E did not have a statistically significant effect on lower respiratory tract infections in elderly nursing home residents. However, a protective effect of vitamin E supplementation on upper respiratory tract infections, particularly the common cold, was observed (3).

Calcium and vitamin D are both essential for the development and maintenance of skeletal health. Calcium plays a vital role in neuromuscular function, many enzyme-mediated processes, blood clotting and in providing rigidity to the skeleton by virtue of its phosphate salts. Over 99% of the body’s calcium is stored in the bone, where, apart from providing mechanical strength, it serves as a mineral reservoir that can be drawn upon to maintain normal plasma calcium. Vitamin D is required to maintain normal blood levels of calcium and phosphate, which are in turn needed for the normal mineralization of bone, muscle contraction, nerve conduction and the general cellular functioning of all body cells. Vitamin D, derived from both endogenous (skin) and exogenous (diet) sources, is converted into 25OHD in the liver and then into 1,25(OH)2D in the kidneys. The latter metabolite controls calcium absorption. However, plasma 25OHD closely reflects vitamin D nutritional status, and because it is the substrate for the renal enzyme that produces 1,25(OH)2D, it could have mainly an indirect and also a direct effect on calcium absorption. A vitamin D shortage would reduce the intestinal absorption of calcium, which could worsen if the diet is deficient of this element. Osteoporosis and its clinical consequence, fragility fractures, are now recognized as major public health problems. Bone mass declines and the risk of fractures increases as people age, especially postmenopausal women. An adequate intake of calcium and vitamin D, including supplementation, has been advocated as a universal primary intervention in the prevention and treatment of high-risk patients. Evidence shows that there is still a high proportion of people with inappropriately low calcium and vitamin D intake and serum levels. For selective groups of people, such as the elderly (frequently older than 70 years), those with low solar exposure and in generally poor or inadequate nutritional condition, guaranteeing a daily intake of at least 1 g of calcium and 700–800 IU of vitamin D with supplements would have beneficial effects on bone health. In those individuals with a high risk of osteoporotic fracture, calcium and vitamin D supplements are necessary but frequently insufficient (4).

Chromium (Cr) is an essential element required for normal carbohydrate and lipid metabolism. Signs of Cr deficiency have been documented on numerous occasions, including elevated blood glucose, insulin, cholesterol and triglycerides, and decreased high density lipoproteins (HDL) in humans consuming normal diets. A review reports that the response to Cr supplementation for glucose, insulin, lipids, and related variables is related to the amount and form of supplemental Cr, the degree of glucose intolerance, and the duration of the study. Subjects with glucose intolerance but not diabetes usually respond to 200 µg of Cr daily as Cr chloride or other more bioavailable forms of Cr (5).

Impaired glucose tolerance results from Cr restriction in animals, and Cr supplementation improves glucose tolerance in diabetic animals. These effects are presumably due to the role of Cr in glucose tolerance factor (GTF), a complex of Cr and nicotinic acid believed to facilitate insulin binding. Humans, however, do not uniformly respond to Cr supplementation. A study was designed to evaluate the possibility that the failure results from inadequate levels of dietary nicotinic acid to serve as substrate for GTF synthesis. Sixteen healthy elderly volunteers were divided into three groups and given either 200 micrograms Cr, 100 mg nicotinic acid, or 200 micrograms Cr + 100 mg nicotinic acid daily for 28 days and evaluated on days 0 and 28. Fasting glucose and glucose tolerance were unaffected by either chromium or nicotinic acid alone. In contrast, the combined chromium-nicotinic acid supplement caused a 15% decrease in a glucose area integrated total and a 7% decrease in fasting glucose. Thus, these data suggest that the inability to respond to chromium supplementation may result from suboptimal levels of dietary nicotinic acid (6). Another study evaluated the effect of chromium supplementation, versus placebo, on insulin levels and serum lipids in a double-blind, randomized trial in 26 young adults (mean age 36 years). Fasting levels of glucose, immunoreactive insulin (IRI), and lipids (total cholesterol, HDL cholesterol, LDL cholesterol, triglycerides) were measured before and after 90 days of daily supplementation with a chromium (III)-nicotinate preparation, containing 220 micrograms elemental chromium, or placebo. However, those individuals within the chromium group with initial fasting IRI levels greater than 35 pmol/l had a significant decrease in IRI level after supplementation despite no significant changes in serum lipids. These subjects may benefit from chromium supplementation by improving insulin sensitivity and cardiovascular risk over time (7). The NHPD recommendations for chromium supplementation in adults to provide support for healthy glucose metabolism are between 2.2-500 µg per day (8).

Increasing evidence also suggests that a higher potassium intake may have beneficial effects on endothelial function, renal disease, arterial compliance, left ventricular (LV) mass and function, and bone mineral density. To determine the effects of potassium supplementation on endothelial function, cardiovascular risk factors, and bone turnover and to compare potassium chloride with potassium bicarbonate, a 12-week randomized, double-blind, placebo-controlled crossover trial in 42 individuals, was carried out. Participants were allocated in random order to take 10 placebo capsules per day for 4 weeks, 10 potassium bicarbonate capsules per day (potassium: 6.4 mmol per capsule) for 4 weeks, or 10 potassium chloride capsules per day (potassium: 6.4 mmol per capsule) for 4 weeks. The study demonstrated that, in individuals who were already on a relatively low-salt and high-potassium intake, both potassium chloride and potassium bicarbonate significantly improved endothelial function. In addition, potassium chloride reduced 24-hour urinary albumin, and potassium bicarbonate decreased 24-hour urinary calcium, calcium:creatinine ratio, and plasma ?CTX, a marker of bone resorption. These results indicate that an increase in potassium intake has beneficial effects on the cardiovascular system and bone health. The 2 potassium salts appear to have a similar effect on most of the cardiovascular parameters studied; however, there are differences between them in the effects on calcium and bone metabolism and urinary albumin excretion (9).

Magnesium is involved in numerous processes that affect muscle function including oxygen uptake, energy production and electrolyte balance. Thus, the relationship between magnesium status and exercise has received significant research attention. This research has shown that exercise induces a redistribution of magnesium in the body to accommodate metabolic needs. There is evidence that marginal magnesium deficiency impairs exercise performance and amplifies the negative consequences of strenuous exercise (e.g., oxidative stress). Strenuous exercise apparently increases urinary and sweat losses that may increase magnesium requirements by 10-20%. Based on dietary surveys and recent human experiments, a magnesium intake less than 260 mg/day for male and 220 mg/day for female athletes may result in a magnesium-deficient status. Recent surveys also indicate that a significant number of individuals routinely have magnesium intakes that may result in a deficient status. Athletes participating in sports requiring weight control (e.g., wrestling, gymnastics) are apparently especially vulnerable to an inadequate magnesium status. Magnesium supplementation or increased dietary intake of magnesium will have beneficial effects on exercise performance in magnesium-deficient individuals. Magnesium supplementation of physically active individuals with adequate magnesium status has not been shown to enhance physical performance (10). The effects of magnesium supplementation on blood parameters were studied during a period of 4 wk in adult tae-kwon-do athletes at rest and exhaustion. Thirty healthy subjects of ages ranging in age from 18 to 22 yr were included in the study. The subjects were separated into three groups, as follows: Group 1 consisted of subjects who did not train receiving 10 mg/kg/d magnesium. Group 2 included subjects equally supplemented with magnesium and exercising 90-120 min/d for 5 d/wk. Group 3 were subject to the same exercise regime but did not receive magnesium supplements. The leukocyte count (WBC) was significantly higher in groups 1 and 2 than in the subjects who did not receive any supplements (p < 0.05). There were no significant differences in the WBC of the two groups under magnesium supplementation. The erythrocyte, hemoglobin, and trombocyte levels were significantly increased in all groups (p < 0.05), but the hematocrit levels did not show any differences between the groups although they were increased after supplementation and exercise. These results suggest that magnesium supplementation positively influences the performance of training athletes by increasing erythrocyte and hemoglobin levels (11).
