The effects of coffee are more potent than those of caffeine alone, since it contains two other stimulants: theophylline and theobromine. These weaker versions of caffeine remain in decaffeinated coffee, making it less than a stimulant-free substitute.
Caffeine works by mimicking or triggering the release of the three primary neurotransmitters (chemical messengers) in the brain: dopamine, adrenaline and noradrenaline. These chemicals make us feel alert, motivated and cheerful. Let's take a look at your response to a cup of coffee:
For the first 30-60 minutes, you feel stimulated and more alert, focused, and motivated. Your mood may improve, and your memory may seem a bit sharper. You might also begin to feel a bit jittery. Then, in an hour or two, as the caffeine is slowly inactivated, you might notice yourself feeling foggy-brained and drowsy, or even irritable. You will likely be craving another cup of coffee. So the vicious cycle of withdrawal, craving and addiction begins. Soon one cup of regular coffee won't do it for you, either: you need a double espresso for the same effect! This response, common to all addictive substances, is called "tolerance."
Some proven health hazards of caffeine include: Overstimulation of the nervous system, leading to irritability, insomnia, rapid and irregular heartbeats and an increased risk of heart attack; elevated blood pressure (hypertension); elevated blood-sugar and cholesterol levels; heartburn and other gastrointestinal problems; fibrocystic breast lumps; diuresis (excessive urination), which can lead to dehydration; increased risk of birth defects if used during pregnancy.
Coffee contains tars, phenols and other carcinogens, as well as traces of pesticides and toxic chemicals used in the growing and extraction processes. At best, we can say that coffee has minor short term mental and emotional benefits, but they are not sustained. Theres a wide variety of natural substances that supply the immediate boost of coffee without the negative side-effects; In fact, they produce more energy and balance neurotransmitters in the brain:
B vitamins such as B5 (pantothenic acid), B3 (niacin), B6 (pyridoxine) and folic acid are natural energizers, essential for the formation of neurotransmitters, and also help your body cope with the effects of stress.
DL-phenylalanine (DPLA): an amino acid, and precursor for tyrosine, which converts dopamine, adrenaline, and noradrenaline. It not only enhances mood and promotes energy, but also relieves pain and controls appetite, at 500 mg 1-3 times daily.

A precursor to the stimulating neurotransmitters dopamine, adrenaline, noradrenaline and the thyroid hormone, thyroxine, it has been used by the military to improve mental and physical performance under stress.

TMG or trimethylglycine enhances neurotransmitter activity and improves energy, mental clarity, and mood. Dose is 250-500 mg once or twice daily.
Coenzyme Q10: stimulates cellular production of energy, is a good antioxidant, enhances energy and endurance. Dose is 30-60 mg once or twice daily.
