I just bought a titanium couple bracelet in Jinzhen, 600 yuan. I searched the internet for a day and found many suspicious things, so I called 3 15 to return the goods, and the merchant gave me a full refund.

The following is some information on the internet, and some are the experiences of people like you and me who once wanted to buy or have already bought:

The health care function of titanium germanium jewelry mainly comes from germanium, and it doesn't matter whether it contains titanium or not;

Titanium and germanium are harmful substances in coal. How many benefits will the two together have? These are rare, dispersed and radioactive elements that are harmful for a long time.

No harm, but actually no influence;

This pseudo-scientific fashion is blown from Japan;

There is no scientific basis for the statement that germanium commodities are good for health;

We often say that negative oxygen ions are beneficial to human body, not negative ions of germanium commodities;

This thing is just an amulet at best,

The effect is between magnetic therapy and wearing Buddha statue;

I bought Jin Zhen! Absolutely false! I fell for it! TV shopping is genuine fake! Help advertise. Don't let friends around you be deceived, and let the manufacturers and salespeople who earn this kind of black-hearted money be rewarded!

It is hereby announced that the production of Jinzhen bracelet produced by our company officially stopped on September 25th, 2008!

Why should such a good thing be discontinued? Not all businesses have heard everything, have they?

Element Name: Germanium

Element symbol: Ge

It exists in coal, iron ore and some silver and copper mines, and also exists in the form of germanate. It can be made from germanium dioxide by carbon reduction. It can also be recovered from the dust in the flue produced by coal-fired boilers.

Obtained from refined copper, zinc and lead.

Germanium, with semiconductor characteristics. It has played an important role in the development of solid state physics and solid state electronics.

Germanium, tin and aluminum belong to the same family in the periodic table of elements. The latter two were discovered and utilized by the ancients, while germanium has not been mined on an industrial scale for a long time. This is not because the content of germanium in the earth's crust is small, but because it is one of the most dispersed elements in the earth's crust, and there are few ores containing germanium.

Effects on human body

The main function of germanium on human body is to restore fatigue; Prevention of anemia; Help metabolism and so on. Many places are used as medical AIDS. But it has not been clinically proved to be effective. At most, they will say: the body will be lighter and the pain will be relieved. If you take it, there have been deaths. What clinical researchers think is dangerous. It will have a bad effect on the kidneys. But in Japan, it is sold in necklaces and bracelets as a health care appliance in the jewelry industry. It is very expensive

So far, it has not been found that germanium is an essential trace element for human body, nor has it been found that organisms are diseased due to lack of germanium, so it is not necessary to supplement germanium under normal circumstances, because the germanium ingested by human body in normal diet is enough. At present, it is found that the beneficial biological effects of germanium are closely related to the existing forms, and it seems that there is no obvious physiological activity. Only some organic germanium compounds can show certain physiological activities.

Distribution and metabolism of germanium in the body

All kinds of natural foods contain germanium to varying degrees, and the daily intake of germanium for adults is about 400-3500ug. Therefore, germanium is ubiquitous in the body, and some enzyme proteins in the body, the cortex and gray matter of the brain all contain trace element germanium. Germanium has no selectivity to various tissues when it enters the body, and can be distributed in various organs, mainly liver, lung, kidney and spleen. Finally, it is quickly excreted through sweat, feces and urine, and most of it is excreted through kidneys and urine.

Second, organic germanium compounds with physiological activity

The most studied organogermanium compounds include organogermanium sesquioxides, derivatives and sulfur-containing coordination organogermanium compounds, and their physiological activities are the most obvious.

Germanium has obvious anti-tumor and anti-inflammatory activities, and there are many other types of organic germanium compounds, most of which have anti-tumor, anti-inflammatory, immune resurrection, sterilization and other biological effects, but because of their high toxicity, they can only be used as medicine.
