“…Therefore, as mentioned above, a reduction of bone formation and increase of bone resorption might be caused by the impairment of mineral intake as well as by Mg 2+ and Ca 2+ deficiency, and could play a negative role in bone growth. However, sufficient intake of individual nutrients such as Ca 2+ and Mg 2+ , or functional drinks that contain replenishing minerals have a beneficial effect on BMD and BMC [ 37 , 38 ]. According to Kang et al ., in a study of the changes of bone metabolism in growing rats caused by Ca 2+ and Mg 2+ , long-term supplementation with deep-sea water, which is rich in Mg 2+ and Ca 2+ , improves bone metabolism, as reflected by increased BMD, BMC and the breaking force of bones [ 38 ].…”

We investigated the effect of Opuntia humifusa (O. humifusa) supplementation on bone density and related hormone secretion in growing male rats. Sixteen six-week-old male Sprague-Dawley rats were randomly divided into two groups; control diet group (CG, n = 8), and experimental diet group (EG, n = 8). The rats in the CG were given a control diet and those in the EG were given 5% O. humifusa added to the control diet for eight weeks. The serum OC level of the EG was significantly higher than that of the CG, and the serum parathyroid hormone (PTH) level of EG was significantly lower than that of the CG. In addition, the femoral and tibial BMD of the EG were significantly higher values than those of the CG, and the tibial BMC of the EG was significantly higher than that of the CG. These results suggest that O. humifusa supplementation has a positive effect on bone density by suppressing PTH and increasing the OC level in growing male rats.

“…Deep seawater is a pure source of various minerals and is far richer in nutrients such as Mg compared to that of surface seawater; and thus it has been the focus of considerable research, particularly with regard to its putative nutraceutical effects. In addition to its use in health food products, cosmetics, beverages, and agriculture, the administration of deep seawater has been shown to be effective in the prevention of atherosclerosis and osteoporosis in animal model studies [ 9 , 19 – 20 ] and appears to improve atopic eczema/dermatitis and postprandial hyperlipidaemia in humans [ 21 – 22 ]. Nigari is refined from deep seawater containing a variety of minerals (mainly Mg) and small amounts of other trace elements.…”

The beneficial effect of magnesium supplementation on exercise performance has been reported by many researchers. In the present study, the effect of nigari, a concentrate of deep seawater containing high magnesium levels, on exercise performance, was examined. Gerbils were given double-distilled water or nigari (18 mg · kg−1, po) orally 30 min before exercise. All animals were subjected to forced exercise on a treadmill for 90 min at three successive speeds of 10, 15, and 20 m · min−1. The retention numbers were recorded. The retention numbers were 85.0 ± 21.0, 46.0 ± 9.7, and 48.0 ± 14.2 in the control group, and 44.0 ± 10.9, 23.0 ± 8.4, and 13.0 ± 4.8 in the nigari-treated group at the three speeds, respectively. The retention numbers were significantly reduced at higher speeds (by 50% at 15 and 73% at 20 m · min−1, respectively) in the nigari-treated group when compared to those of the control group, respectively. Thus, nigari administration appeared to reduce retention numbers and enhance exercise performance in gerbils.

“…All experiments were approved by the Animal Studies Committee of Sunmoon University. The composition of the experimental diet, as shown in Table 1, was 35% carbohydrate, 20% protein, and 35% fat and was substituted for a portion of the fat component based on AIN-76 [25]. The food efficiency ratio (FER) was calculated by the total weight gained divided into the total food intake for the experimental period.…”

This study purposed to examine the effect of puer-tea supplementation on antioxidant enzymes during acute exercise of rats. Thirty-two rats were randomly divided into four groups (HS : high fat diet sedentary group, n=8; HE : high fat diet acute exercise group, n=8; PS : puer-tea gavaged sedentary group, n=8; puer-tea gavaged acute exercise group, n=8), The high-fat diet was composed of 35% carbohydrate, 20% protein, and 35% fat. In the acute exercise group, the rats were swam for 60min (3% load/weight) before anesthetized with ether. The results showed that EFT of PS group was significanlty lower than the HS group (p < .05). In the blood components, there were no significantly different in the serum glucose, TC, HDLC, but TG level of exercise group were significantly lower than the control group (p < .01), respectively. In addition muscle glycogen content of PS and PE were significantly higher than the HS and HE (p < .01), respectively, and MDA content of PE was lower than the PS group (p < .01). Furthermore, Cu,Zn-SOD protein expression of PS group was significantly higher than the HS group (p < .05), and GPx protein expression of PE and HE were significantly higher than the PS and HS (p < .01), respectively. From these results, puer-tea supplementation has a positive effect on antioxidant activity because of puer-tea supplemented group was showed higher value of Cu,Zn-SOD protein expression, and could be an important dietary antioxidant source as well.
