Source of Calcium in Supplements – Which Compounds are Used as a Source of Calcium in Supplements?

Although many calcium salts are being utilized in making calcium supplements, the most prominent ones used as a source of calcium in supplements are calcium carbonate, calcium phosphate and calcium citrate. Out of these, calcium carbonate has been found to be the best, as it provides up to 40% of elementary calcium, higher than all other calcium salts.

A variant on calcium carbonate known as coral calcium, which is obtained from fossilized coral reefs above sea level is also used as a source of calcium in supplements. This source is essentially calcium carbonate but also contains traces of many other minerals like magnesium, sodium and potassium in just the right quantities.

Calcium orotate is another compound used in making calcium supplements, both liquid and in tablet form. This salt is known for its ability to suppress appetite and therefore assists in quick weight loss. Since it is a source of calcium, it can also be used to control calcium deficiency without eating a lot of food, especially coming from animal sources.

Because of our busy routines today, we don’t get to eat healthy diets anymore. Owing to this fact, most of us are calcium deficient and need calcium supplements or tablets to overcome this deficiency and avoid degenerative diseases in old age. Postmenopausal women are at a high risk of developing these diseases, particularly bone disease or osteoporosis. They should be consuming up to 1500 mg of calcium on a daily basis.

Coral calcium obtained from the Okinawa island of Japan is an excellent source of calcium in supplements. Many manufacturers across the globe are making use of this special kind of coral calcium to make good-quality and effective calcium supplements. However, you should be careful in buying these supplements because only marine grade Okinawa coral calcium is beneficial and better than normal coral calcium.

These products are made with totally natural ingredients, and therefore they don’t have any side effects associated with their consumption. However, people who are not used to consuming tablets or capsules regularly may experience constipation or stomach cramps in the first few days of the course.

Pregnant and lactating women are advised to check with their doctor before using any kind of dietary supplement to fulfill their nutritional needs. Food is the best source of calcium and all other minerals. However, when you are deficient of any of these nutrients, you do need the assistance of nutritional supplements to overcome this deficiency and avoid health complications.

Do We Really Get Calcium From Milk and Dairy Products?

Soil is the original source of all calcium, which is then absorbed by plants and incorporated into their tissues. Animals then eat the plants to obtain their calcium and other minerals. There is sufficient calcium in plants to grow the skeletons of the biggest animals on earth such as the elephant. It is not hard to therefore accept that there is sufficient calcium in plants to grow a human skeleton. In fact most humans who have walked this earth have been able to grow strong healthy skeletons without cow’s milk or calcium supplements.

Calcium is involved in bone formation and nerve, muscle and blood vessel function. Levels of calcium are maintained by the gastrointestinal tract, bone and kidney. If our diet is low in calcium then more will be absorbed from the gut and less excreted from the kidneys. Conversely if excess calcium is consumed, less will be absorbed and more excreted. However there is the potential for a dangerous increase in free calcium.

Calcium is the most abundant mineral in the human body. 99% of the body’s pool of calcium is stored in bones (about 1 kg). Of the remaining 1%, 55% of it is bound to protein and organic ions. Only 45% is free (unbound).

Unbound calcium is particularly dangerous because it gets deposited in tissues, including arteries, and therefore increases the risk of cardiovascular disease. An increase of free calcium by 2% causes a massive deposition. Is there much point advising people to supplement with calcium when it ends up going to the arteries and not to the bones? There are implications against taking regular high dose calcium supplementation because it appears to be going everywhere except bones. Dolomite or coral calcium in particular is a problem as they are essentially finely ground up rock which is poorly absorbed with any that is absorbed usually ending up in tissues other than bones.

In Western countries the usual intake of calcium is around 800-1000mg/day while in developed countries it is around 300-500mg/day. Some women in Africa and Japan have intakes of around 200mg/day and do not get osteoporosis.

Most of the scientific literature supports the belief that the majority of the older population is massively overdosed on calcium and suffering from calcium toxicity. Excess calcium in arterial walls is directly correlated to increased risk of heart disease and chronic degenerative diseases. Many breast cancers have calcium deposits in and around them. Research on the use of calcium in preventing osteoporosis is not conclusive whereas the research is convincing that supplemental calcium fuels the progression of atherosclerosis and therefore heart attacks. Studies also show that calcium supplementation is unlikely to reduce the risk of fracture, either in childhood or later life. These studies also pointed out that populations that consume the most cow’s milk and other dairy products have among the highest rates of osteoporosis and hip fracture in later life.

Osteoporosis is NOT caused by an inadequate intake of dairy products. Populations in countries that do not have access to dairy products do not develop osteoporosis. Australia and the US are the 2 countries with the highest intake of dairy products and have the highest incidence of osteoporosis. Dairy foods do contain calcium but they also contain acidic proteins which cause a net loss of calcium from bone as calcium is pulled from the bones to lower the acidity caused by the acidic milk proteins.

Studies have found no relationship between the intake of dairy products and the strength of children’s bones and that postmenopausal women who consumed 3 extra glasses of cow’s milk/day for a year lost more bone than those who didn’t drink the extra milk.

The bottom line if you want to make sure you are getting your daily intake of calcium then get it from plants and nuts not dairy. Plants contain lots of readily absorbable calcium so if you are eating green leafy vegetables, broccoli or seaweed you are more than enough calcium.

Are There Really Effective Weight Loss Supplements?

The overweight are always looking for ways to help improve the success of their weight loss efforts. We all know that diet and exercise are critical to losing weight and keeping it off, but finding ways to help us burn those extra calories is certainly welcome.

There have been many substances reported to be effective in helping lose weight faster and easier. But, do any of them actually work? Well, that’s just the question that one review attempted to answer.

An article published in Obesity Reviews evaluated conjugated linoleic acid, diglycerides, medium-chain triglycerides, green tea, ephedrine, caffeine, capsaicin and calcium for their ability to speed weight loss by increasing the metabolism, inhibiting fat absorption or some other mechanism. In addition, this review evaluated the feasibility of actually using the substance as a weight loss supplement. The following details some of the substances that were reviewed in this article.

Conjugated linoleic acid

Conjugated linoleic acid (CLA) is a term for a group of geometric and positional isomers of octadecadienoic acid (linoleic acid) that occur naturally in food. The primary dietary sources of CLA are animal-based products like meat and dairy products. In animals, CLA has been shown to reduce body fat and increase lean body mass, particularly in mice. However, study results in humans have produced inconsistent results.

Calcium

Calcium and dairy products have gained a great deal of attention in the last few years for the possibility that they may be instrumental in helping to lose weight. There have been several significant studies that suggest that when people reduce their overall calorie intake, while increasing their intake of dairy products, they lose more weight than when restricting calories alone. Studies have also shown that, in general, people who consume low fat dairy products daily tend to weigh less and have less body fat than those who do not.

But what about people who use supplements rather than dairy products to increase their calcium intake? Different studies have produced different results in some cases; however, it appears that the most effective way to use calcium to help with weight loss is through dietary dairy calcium, rather than through calcium supplements alone. Because of this, researchers believe that it is not solely the calcium that helps with weight loss, but some combination of calcium and another substance in the dairy products.

If you’re aiming to increase your calcium intake to help promote weight loss, it is suggested that you consume at least 1400 mg of calcium daily.

Ephedrine and Caffeine

In recent years, there have been a multitude of weight loss supplements on the market that contained a combination of ephedrine and caffeine. These supplements were shown to be effective in increasing your metabolic rate.

However, ephedrine has been banned in the US because it was found to be unsafe. Many users have reported dangerous side effects from the use of ephedrine; including death from heart failure. Therefore, regardless of its effectiveness, using ephedrine for weight loss is not realistic.

Caffeine, however likely has some effect on the metabolism on its own. In many studies, people who consumed caffeine have been shown to lose more weight than those who did not consume caffeine, when placed on the same low calorie diet. In addition, studies have shown that caffeine drinkers tend to weigh less than those who never consume caffeine.

The problem with caffeine alone is that since most of us consume caffeine whether or not we’re trying to lose weight, it may have little effect on its own when we go on a diet. If we’re already consuming caffeine, we may need to increase the amount we consume significantly in order to see our bodies respond to it. Increasing your caffeine intake too dramatically can cause sleeplessness, jitters and increased heart rate and blood pressure, so this may make it unfeasible.

Green Tea

Green tea has been shown in many studies to increase metabolism, lower cholesterol levels, burn fat and inhibit the absorption of dietary fat. Part of green tea’s magic comes from the fact that it contains caffeine, but this is not its only weight loss property.

Green tea is a potent source of anti-oxidants, which is believed to be part of the reason that it seems to help burn fat. Green tea’s anti-oxidants are some of the most powerful found in any food, and they seem to help the body burn fat and reduce the amount of dietary fat that turns into body fat.

Green tea can be an effective weight loss supplement, and has virtually no side effects. In addition, green tea offers many health benefits. Green tea has been shown to lower cholesterol and prevent many diseases like heart disease and cancer. So, green tea is one weight loss supplement that can be added to your diet with the knowledge that it’s an overall healthy dietary change.

So, as you can see, there are many products that may have some effect on your ability to lose weight. Each person’s body is different, and for this reason, supplements may affect each person differently. As long as a supplement is safe, there’s no reason not to try it to see if it works for you. If you do find a supplement that’s effective, you’re one step closer to achieving your weight loss goals, and with less effort, as well.
