FISH OIL
Fish oil, which is rich in EPA and DHA omega-3 fatty acids, has many health benefits. I’m only going to mention a few of them in this post.
HEART DISEASE
High blood levels of triglycerides and an unhealthy ratio of good HDL cholesterol to bad LDL cholesterol are commonly thought to increase the risk of heart […]

ZINC
The immune system is depressed by even a moderate zinc deficiency because zinc is required for the development of T-Lymphocytes, a type of white blood cell that fights infections (Zinc and immune function: The biological basis of altered resistance to infection. Am J Clin Nutr. 1998;68:447S-463S). There is also evidence that a mild zync deficiency […]

SAW PALMETTO
If you happen to be male and over the age of 35, saw palmetto can be useful to prevent an enlarged prostate, a a nearly universal result of the aging process in men.
Some of the symptoms of an enlarged prostate include frequent urination, especially at night, a less forceful urine stream, and dribbling after […]

VITAMIN B12
Vitamin B12 deficiency is present in 5-40 percent of the general population. Such deficiency in the long term can cause neurological problems such as irreversible nerve cell death and symptoms such as acute psychosis, dementia, depression, spasticity, abnormal gait, ataxia (lack of coordination and ability to balance), numbness, and incontinence.
Some of the populations which […]

GINKGO BILOBA
Gingko biloba has been shown to prevent oxidative damage to mitochondria (the part of the cell that converts nutrients to energy), one marker of old age, particularly in the brain and liver (A Ginkgo biloba extract (EGb 761) prevents mitochondrial aging by protecting against oxidative stress, Free Radic Biol Med. 1998 Jan 15;24(2):298-304).
Gingko biloba […]

FOLIC ACID
Folic acid supplementation has been found to lower homocysteine levels in the blood, regardless of sex, age, or body mass index (The Effects of Folic Acid Supplementation on Plasma Total Homocysteine Are Modulated by Multivitamin Use and Methylenetetrahydrofolate Reductase Genotypes, Arteriosclerosis, Thrombosis, and Vascular Biology. 1997;17:1157-1162). The reason this is important is because high […]

CALCIUM
In a survey of studies published from 1975-2000 which explore the relationship between calcium intake and bone health, researchers found that, “of 52 investigator-controlled calcium intervention studies, all but two showed better bone balance at high intakes, or greater bone gain during growth, or reduced bone loss in the elderly, or reduced fracture risk. This […]

CHROMIUM
Chromium indirectly effects glucose metabolism by increasing insulin sensitivity.
Insulin is a hormone secreted by the pancreas. In this case, the effect of chromium isn’t to help the pancreas to create more insulin, but rather to make more efficient use of the insulin the pancreas secretes. 
In a review of the studies done on chromium supplementation, 12 out […]

DHEA
DHEA is a hormone that is produced by cholesterol, when signaled to do so by ACTH, a substance secreted by the pituitary gland. DHEA in turn is involved in the manufacture of more hormones, such as the corticosteroids, estrogen, progesterone, and testosterone. DHEA production naturally decreases throughout life, until the body makes only 10-20% at […]

Here are a few examples of secretagogues (a substance that can stimulate the secretion of human growth hormone):
GLUTAMINE
A study done at the Louisiana State University College of Medicine showed that taking relatively low oral doses of glutamine (2 grams) elevated levels of human growth hormone (HGH) in the blood more than four times that of […]
