Lack of vitamins in your body is the result of increasing the destructive chemistry within your system. Certain chemicals eat precious chemical elements of your physical body, emotional body, and mental body and lead your bodies into depression.
Of course, through certain injections or pills or vitamins these elements can be restored in your system. But if the cause is not eliminated, the depletion becomes chronic and permanent. If the cause of depletion is not eliminated within a certain period of time and the vitamins are injected or dumped into your system, they turn into devitalizing and even poisoning factors.
The most important thing is to find why certain chemicals are disappearing from your brain, your body, even from your emotional and mental bodies. Usually when chemicals disappear from your mental and emotional bodies, corresponding chemicals also disappear from your brain, nervous system, blood, and glands.
Certain ways of thinking, irritation, fear, vanity, ego, greed, and separatism sap precious chemicals from your system. If your chemistry is balanced, it takes time to hurt yourself. If your chemistry is poor, either you suffer or you sap the chemistry of those who are near you.
Physical and emotional and mental chemism must be balanced to have a really healthy person. Often one of these bodies supplies chemistry to the others or drains chemistry from them.
