Age Management or Anti Aging Medicine – By Dr. Judi Goldstone

Published by under Anti Aging - Hormones

It is no longer necessary to accept the mental and physical decline associated with aging. A century ago the average life expectancy was 43 to 47. Today, life expectancy has almost doubled, due mostly to advances in medicine and technology. The rapid rate of these advances may put one in position to take advantage of cutting edge technologies in the pipeline, such as genetic engineering, stem cell transplants, therapeutic cloning, nanotechnology, and artificial organs. However, a longer life span is only desirable if living longer means living stronger, healthier, and without disabilities.
This is the premise of Anti-Aging Medicine, which is also known as Age Management Medicine, Longevity Medicine, Preventive-Regenerative Medicine, or Optimal Aging Medicine. Preventive-Regenerative Medicine is a new specialty of heath care based on early detection, prevention, and reversal of the degenerative effects of aging. The primary goal is living healthier for a longer period of time. The Anti-Aging specialty began in 1993 when twelve forward thinking physicians formed the American Academy of Anti-Aging Medicine (A4M). Today, the Academy is composed of 20,000 physicians and scientists from over 70 countries. It is the fastest growing scientific society in the world. The Academy is devoted to examining scientific research pertaining to: the causes of illness; aging; and the decline in physical and mental function as aging occurs. The principals of Preventive-Regenerative Medicine are well documented in medical and scientific journals, and are based on sound and responsible medical care.
Research suggests that aging is likely due to a combination of causes. Some theories of aging include: degeneration of bodily functions due to hormone decline, free radical damage due to lifestyle factors, chronic inflammation, loss of DNA’s ability to reproduce, or too much insulin. When these events are controlled or prevented, the likelihood of illness and disability is reduced or prevented, and it becomes possible to maintain good general health, strong muscles and bones, an efficient immune system, sharp memory, and peak mental and physical function at any age. While traditional medicine focuses on treating the effects of the aging process, Anti- Aging Medicine focuses on treating or preventing the causes of aging. Stated differently, traditional medicine predominately treats external symptoms that have internal causes, while Anti-Aging Medicine addresses the internal causes in order to prevent external symptoms. The different approach may sound subtle, but it can produce substantial differences in a person’s health and well being.
How does Preventive-Regenerative Medicine produce these results? At Griffin Medical Dr. Goldstone customizes a program for each individual after performing a physical exam, obtaining a comprehensive medical history, and conducting a nutritional and fitness evaluation. In addition, Dr. Goldstone obtains an advanced blood analysis, that includes blood count, body chemistries, blood sugar, organ function, hormone levels, cardiovascular and cancer risk factors, and inflammatory markers. She then designs a program based on replacement of deficient hormones and neutraceuticals, exercise, stress reduction, diet, and inflammation control. Bio-identical hormones (i.e., identical to human hormones) are used when replacement is necessary. Hormone levels are restored to a youthful range, and the patient’s progress is regularly monitored by physical exam and lab work, typically every three months for the first year, and every six to twelve months the reafter.
Judi Goldstone, MD is California native and a cum laude graduate of the University of California at Los Angeles. She received her medical degree from Mount Sinai School of Medicine in New York, where she graduated in the top third of her class. She is certified by the American Board of Internal Medicine and has been practicing internal medicine in Southern California most of her career. For the past 8 years Dr Goldstone began practicing bariatric(weight loss) and wellness medicine. She is an active member of the American Society of Bariatric Physicians and the American Academy of Antiaging and Regenerative Medicine. Dr. Goldstone has extensive experience in bio identical hormone replacement therapy, growth hormone replacement, menopause, andropause (male menopause), neutraceutical supplementation, nutrition, and weight loss.

Quality Assurance Alert – Toxic Chemicals in Raw Materials

As you know by now, Griffin Medical Group only prescribes pharmaceutical vitamins and supplements. We are one of only a few medical groups that seek quality in all the products we recommend. We feel that we are the leader in quality assurance. Contamination in natural products is a huge issue, whether the material comes from China, India, Europe or the United States. It is not where the material comes from that matters, but how thoroughly it was tested for purity before it gets put into a product and sold. Here are a few of the solvent tainted raw materials that we have been advised of by the pharmaceutical companies we work with. The following raw materials were deemed unacceptable to pharmaceutical supplement companies. Continue Reading »

Vitamin D3 Important for Male and Female Health

Published by under Vitamin D3

Two recent studies indicate higher levels of vitamin D are associated with a reduced risk of breast and prostate cancer.

In the newest of the two studies, researchers investigated the relationship between serum 25-hydroxyvitamin D [25(OH)D] levels (a measurement of vitamin D3 levels in the body) and the incidence rates of breast cancer in 107 countries. The researchers also looked at the number of breast cancer cases that occurred at varying latitudes since past studies have found lower breast cancer rates in areas that receive higher amounts of sunlight. The lower breast cancer rate in these areas is thought to be attributable to the fact that the skin makes vitamin D from sunlight. Continue Reading »

D-Ribose and Creatine Increase Mitochondrial Energy Production

Published by under Creatine - Whey,D-Ribose

A series of recent articles in Vitamin Research News have examined aspects of the Mitochondrial-Free Radical Theory of Aging, describing how the declining function of mitochondria— the tiny organelles responsible for producing ATP— contribute to aging and the diseases of aging. Additionally, the articles outlined a number of nutritional approaches aimed at restoring functional performance to aging mitochondria to increase their ability to produce ATP at more youthful levels.
Here we present additional substances that are also proven to enhance mitochondrial oxidative phosphorylation and energy production. These include:

D-Ribose—Energy Producing ATP Substrate
Ribose is a naturally occurring 5-carbon sugar produced in the body from glucose (Fig. 1). In addition to serving as the carbohydrate backbone for ribonucleic acid (RNA) and deoxyribonucleic acid (DNA), ribose is also an essential ingredient in the manufacture of ATP. The mitochondria found in high-energy-output organs—such as the heart, liver, adrenals, GI tract, brain, muscles and endocrine glands—utilize two methods for building or conserving cyclic nucleotides like ATP, ADP, and AMP.
The first process by which these nucleotides are synthesized is the de novo pathway, in which nucleotides are made “from scratch,” starting with ribose. This is the slower of the two pathways.
The second, faster pathway, is the salvage pathway, in which the mitochondria “pick up the pieces” of ATP metabolites to form new ATP. In this manner ribose enables the cells to quickly and efficiently recycle (i.e., salvage) the end products formed by the breakdown of ATP to form new ATP molecules. Thus, this is known as the salvage pathway of ATP formation.
Ribose is essential for both the salvage and de novo reactions to work. Ribose is formed in the body from glucose, through a process known as the pentose phosphate pathway (Fig. 2). Aside from this relatively time-consuming pathway, there are no foods able to provide enough ribose to rapidly restore ribose levels, should the need arise, as when exercising or working, and especially during a heart attack or stroke.

Restoring Ribose Levels
Scientists have found that oral or intravenous ribose can rapidly restore ribose levels in nerves and muscles. Ribose supplementation can dramatically improve recovery of failing ATP levels during and following acute or chronic anoxia or ischemia. Research has shown that taking ribose has a positive effect on ATP production in all muscle fiber types, especially the heart. Ribose supplementation increases the de novo production of ATP through oxidative phosphorylation by 340 to 430 percent. Ribose also activates the salvage pathway, causing nucleotides to be revitalized into the manufacture of ATP by over 700 percent.

Ribose and Cardiovascular Diseases
Dr. Wolfgang Pliml and colleagues in Germany demonstrated that oral administration of ribose is effective in increasing the heart’s tolerance to ischemia (reduced blood flow). Twenty patients diagnosed with coronary artery disease completed two treadmill tests on consecutive days to establish pain thresholds for each patient. The researchers then gave each patient 60 grams of ribose per day for three days, and administered another treadmill test. Patients supplemented with ribose were able to walk further before pain symptoms occurred than those given the placebo.1
In a second study, 12 patients diagnosed with unstable coronary artery disease and congestive heart failure were administered five grams of ribose, three times daily, for three weeks. Evaluation by pre- and post-ribose echocardiogram revealed improvement in many parameters, including stroke volume index, ejection fraction, and left ventricular systolic volume.2

Ribose and Athletic Performance
Ribose has also been shown to increase athletic performance. Supplementation (ten grams per day) in young male recreational bodybuilders resulted in significant increases in muscular strength and total work performance after four weeks, compared with pre-treatment levels. No changes were noted in those using a placebo.3
Another study of seven healthy men who performed two sessions of bicycle ergometry to exhaustion at a one-week interval indicated that ribose improved efficiency of energy production, as evidenced by reduction of oxidative stress during vigorous exercise. Prior to the second trial, the subjects ingested seven grams of ribose. Ribose ingestion resulted in a reduction of urinary MDA (an indicator of oxidative stress), and lower heart rates at the same intensity of exercise as compared to the unsupplemented group.4

Creatine—Energy Enhancing Supplement
Creatine is an essential, natural substance that is synthesized in the body from three amino acids: glycine, arginine, and methionine. Creatine plays a very powerful role in energy metabolism as a muscle fuel in its role in regenerating ATP.
Operating through the ATP/ADP cycle (Fig. 3), creatine phosphate maintains ATP levels by serving as a reservoir of high-energy phosphate bonds in muscle and nerve tissues. The energy required to rephosphorylate ADP into ATP depends on the amount of phosphocreatine (PCr) stored in muscle tissues. As phosphocreatine is depleted during exercise, energy availability declines due to a loss of ability to resynthesize ATP at the rate required.
While scientists have been aware of creatine since 1832, it was not tested as a performance-enhancing nutrient until 1943, when researchers learned that creatine supplementation extended the cycling times of athletes.5 This nearly-forgotten, single, isolated report languished in the medical literature for over 50 years. However, a number of studies have now corroborated this early study, showing that creatine enhances both strength and endurance in athletes. In one study, creatine was given to 25 football players who had reached a plateau while undergoing a weight-training program. After 28 days of supplementation with creatine, researchers measured a 41 percent increase in “lifting volume” (sum of all lifts).6
Another five-week study of 42 football players also showed gains in strength and mass,7 as did a study of 29 women who took supplemental creatine for ten weeks.8 Some researchers have shown strength gains with as little as five to seven days of supplementation.9,10

Creatine Increases Strength and Energy in Older Adults
Because older people have lower levels of energy-producing muscle phosphocreatine,11 researchers examined creatine to see if supplementation could help seniors overcome this deficit. Subsequent studies have demonstrated that supplemental intake of creatine can effectively increase the available “pool” of creatine stored in muscles and enhance the capacity of older subjects to produce phosphocreatine. In 1998 Smith and colleagues administered creatine to younger (average age, 30) and older (average age, 58) men and women, and then tested their ability to perform a leg exercise. Both older and younger subjects experienced increased muscular endurance. In addition, the phosphocreatine resynthesis rate (PCr) of the older subjects was restored to that of youthful adults (Fig. 4).12
Also in 1998, Rawson and colleagues at the University of Massachusetts demonstrated that five days of creatine administration to a group of older men resulted in a small increase in lean body mass, and a slight improvement in exercise performance.13 This short study was followed up by a larger (20 male subjects, ranging in age from 60-82) and longer (30 days) study in which the subjects were first given a loading dose (20 grams per day) for ten days, followed by four grams of creatine per day for 20 days.14 At the end of the study, six of the ten creatine users reported an increased feeling of muscle strength or less difficulty performing daily activities. Five subjects demonstrated an increase in body mass, three showed an increase in arm strength, and four demonstrated reduced leg fatigue. One subject increased in all three measures. The authors concluded modestly that creatine might have a beneficial effect on reducing muscle fatigue.
Scientists at the University of Saskatchewan conducted a double blind study of the effects of creatine and a weight training program in men over 70. They demonstrated a significant advantage of creatine over placebo in terms of increased lean body mass, reduction in body fat, and increased muscular strength, and endurance.15

Cardiovascular Benefits of Creatine
Creatine is not just of benefit to athletes. In a study of older men (ranging from 43 to 70 years) suffering from chronic heart failure, researchers noted improvements in exercise performance and increased muscle creatine and phosphocreatine levels after ten days’ ingestion of 20 grams of creatine each day.16
In Italy, physicians administered six grams of creatine each day to 13 patients hospitalized with congestive heart failure. After four days, they noted a reduction in heart size, reduced vascular resistance, and increased ejection fraction—all indicators of improved heart function.17

Neuroprotective Effects of Creatine
In a review article, Tarnopolsky concluded that creatine monohydrate supplementation results in an increase in skeletal muscle total and phosphocreatine concentrations, increased fat-free mass, and enhanced high-intensity exercise performance in young healthy men and women.18 He also noted “neuroprotective effects, which have been proposed to be of benefit in Parkinson’s disease, Alzheimer’s disease, ALS, and after ischemia.” He concluded that creatine appeared to have potential to attenuate age-related muscle atrophy and strength loss, as well as to protect against neurodegenerative disorders.
Shortly after Tarnopolsky’s review, FDA granted “orphan drug status” to creatine as a treatment for patients with amyotrophic lateral sclerosis (Lou Gehrig’s disease), based on creatine’s demonstrated ability to enhance cellular energy production. In addition, a European patent has also been issued for the use of creatine compounds to prevent aging effects and to treat muscle atrophy.19

Conclusion
Creatine and ribose, acting at the mitochondrial level, enhance muscular, cardiovascular, and neurological function. Although high optimal doses of creatine and ribose were used in many of the studies cited in this article, other researchers have shown that regular, long term use of lower doses may be equally effective. For greatest effect these substances should be consumed on a continuous basis (around the clock), and especially prior to high energy requirements.

Turmeric Component Maintains Healthy Blood Sugar Levels in Animal Study

Published by under Turmeric

Curcumin, the compound in turmeric responsible for its yellowish color, improved insulin resistance and glucose tolerance in diabetic mice, according to the results of a new study.

The study authors investigated the effect of curcumin on insulin resistance and glucose tolerance in male diabetic mice and age-matched lean non-diabetic controls. Insulin resistance occurs when the body, after exposure to a constant onslaught of high blood sugar, needs to produce more and more insulin in order to feel insulin’s blood sugar stabilizing effects.

Both non-diabetic and diabetic mice were fed with or without curcumin for six weeks. At the study’s conclusion, there were a number of beneficial effects in the animals given the turmeric component. Curcumin significantly lowered blood glucose and levels of glycosylated haemoglobin HbA(1c), which researchers use as an indicator of blood glucose regulation. Curcumin also suppressed body weight loss in diabetic mice and reduced insulin resistance.

Furthermore, the researchers noted beneficial effects on the liver in the diabetic animals given curcumin. Activity of an enzyme that is important to the conversion of glucose into glycogen, which serves as the body”s main carbohydrate store, was higher in the diabetic mice given curcumin compared to the diabetic mice that did not receive the compound. The higher activity of the enzyme seen in the diabetic animals given curcumin is thought to inhibit the post-meal rise in glucose.

The turmeric-derived component also significantly lowered cholesterol and triglyceride concentrations and significantly reduced lipid peroxidation by virtue of its ability to raise antioxidant levels in the liver. In mice without diabetes, curcumin had no effect on blood glucose, plasma insulin, and glucose regulating enzyme activities.

The study authors wrote, “These results suggest that curcumin seemed to be a potential glucose-lowering agent and antioxidant in type 2 diabetic mice, but had no effect in non-diabetic mice.”
