Spirulina, wheatgrass and barley grass supplements, are they really good for us?

Curious, I've been taking 6-12 spirulina supplements everyday for a month and have felt MUCH superior (whether that's just my subconscious telling me I do is up for debate) but are the three any good for us??

THANKS!

SPIRULINA
World's highest beta carotene food reduces long term health risks.
Spirulina beta carotene is ten times more concentrated than carrots. So even if you don't eat the suggested 4 to 9 servings of fruits and vegetables each day (most people eat only 1-2, including french fries), get your natural beta carotene insurance from spirulina to help support your body's defenses.
60% easy-to-digest vegetable protein without the fat and cholesterol of meat.
People are eating less meat and dairy protein because they want to lower fat, cholesterol, and chemicals in their diet. Spirulina is the highest protein food with all the essential amino acids and has only a few calories to keep your waistline where you want it.
A rare essential fatty acid is a key to health.
Gamma-linolenic acid (GLA) in mother's milk helps develop healthy babies. Studies show nutritional deficiencies can block GLA production in your body, so a good dietary source of GLA can be important. Spirulina is the only other whole food with GLA.
Iron for women and children's health.
Iron is essential to build a strong system, yet is the most common mineral deficiency. Spirulina is rich in iron, magnesium and trace minerals, and is easier to absorb than iron supplements.
High in Vitamin B-12 and B Complex.
Spirulina is the highest source of B-12, essential for healthy nerves and tissue, especially for vegetarians.
Uncommon phytonutrients for health and cleansing.
Scientists are discovering the benefits of polysaccharides, sulfolipids & glycolipids, and the rainbow of natural pigments that give spirulina a deep green color. Green (chlorophyll), blue (phycocyanin) and orange (carotenoids) colors collect the sun's energy and power growth. Chlorophyll is a natural cleanser and is often referred to as nature's green magic.

WHEATGRASS
Mixed (juiced) wheatgrass is essentially liquid chlorophyll…powdered in your supplements most likely. What's the greatness about chlorophyll?
Wheatgrass Juice is one of the ideal sources of living chlorophyll available.
Chlorophyll is the first product of light and, therefore, contains more light energy than any other element.
Wheatgrass juice is a crude chlorophyll and can be taken orally and as a colon implant without toxic side effects.
Wheatgrass is high in oxygen like all green plants that contain chlorophyll. The brain and all body tissues function at an optimal level in a highly-oxygenated environment.
Chlorophyll is anti-bacterial and can be used inside and outside the body as a healer.
Dr. Bernard Jensen says that it only takes minutes to digest wheatgrass juice and uses up very tiny body energy.
Science has proven that chlorophyll arrests growth and development of unfriendly bacteria.
Chlorophyll (wheatgrass) rebuilds the bloodstream. Studies of various animals have shown chlorophyll to be free of any toxic reaction. The red cell count was returned to normal within 4 to 5 days of the administration of chlorophyll, even in those animals which were known to be extremely anemic or low in red cell count.
Farmers in the Midwest who have sterile cows and bulls put them on wheatgrass to restore fertility. (The high magnesium content in chlorophyll builds enzymes that restore the sex hormones.)
Chlorophyll can be extracted from many plants, but wheatgrass is better because it has been found to have over 100 elements needed by man. If grown in organic soil, it absorbs 92 of the known 102 minerals from the soil.
Wheatgrass has what’s called the grass-juice factor, which has been shown to keep herbivorous animals alive indefinitely.
Dr. Ann Wigmore and institutes based on her teachings has been helping people get well from chronic disorders for 30 years using wheatgrass.
Liquid chlorophyll gets into the tissues, refines them and makes them over.
Wheatgrass Juice is a superior detoxification agent compared to carrot juice and other fruits and vegetables. Dr Earp-Thomas, associate of Ann Wigmore, states that 15 pounds of Wheatgrass is the equivalent of 350 pounds of carrot, lettuce, celery, and so forth.
Liquid chlorophyll washes drug deposits from the body.
Chlorophyll neutralizes toxins in the body.
Chlorophyll helps purify the liver.
Chlorophyll improves blood sugar problems.
In the American Journal of Surgery (1940), Benjamin Gruskin, M.D. suggests chlorophyll for its antiseptic benefits. The article advocates the following clinical uses for chlorophyll: to clear up foul smelling odors, neutralize Strep infections, heal wounds, hasten skin grafting, cure chronic sinusitis, overcome chronic inner-ear inflammation and infection, reduce varicose veins and heal leg ulcers, eliminate impetigo and other scabby eruptions, heal rectal sores, successfully treat inflammation of the uterine cervix, get rid of parasitic vaginal infections, reduce typhoid fever, and cure advanced pyorrhea in many cases.
Wheatgrass Juice cures acne and even
