◎ Vitamin C

A smoker has many different types of reactive oxygen species (ROS) in the body, also known as free radicals, which can cause cellular damage, or even the formation of cancer.? Supplementing the body with vitamin C can increase the body's anti-oxidating ability, thereby reducing the damage to tissues.? Intake of an adequate amount of vitamin C not only strengthens our immune system, it also suppresses the desire to smoke cigarettes.? Many would even use it as a means of quitting smoking.

◎ Soy Isoflavone

Smoking causes the formation of a large number of free radicals in our bodies. These free radicals can damage the immune system and body tissues. Soy isoflavone is a good anti-oxidant, as it protects our bodies from the invasion of the free radicals and the effects of the radioactivity, chemicals, insecticides, and environmental pollutions. Smoking can also cause abnormal secretion of female hormones, increasing the chance of osteoporosis. Therefore, female smokers should increase the intake of food that contains soy isoflavone in order to lower the chance of having bone abnormalities. Soy isoflavone can suppress the proliferation of protein tyrosine kinase, which in turn will prevent the formation of skin pigmentation.

◎ Vitamin B Complex

The vitamin B complexcan help releasing the tension in a smoker, reducing the anxiety and improving the quality of sleep. In addition, when the serum level of nicotine increases, our body relies on the liver to detoxify. A heavy smoker put a large amount of strain on the liver. The vitamin B complex can help improve the liver function, speed up metabolism, repair damaged liver cells, and help with liver detoxification, thereby reducing the burden on the liver.

◎ Calcium

Calcium is not readily absorbed into a smoking person's system, resulting in the loss of calcium. A smoker should take calcium supplement to avoid the incidence of osteoporosis.
