Fatigue is a common complaint. Often,
it is transient
or can be attributed to a definable organic illness. Some patients present with persistent
and disabling fatigue, but show no abnormalities on physical examination or screening
laboratory tests. In these cases, the diagnosis of
chronic fatigue syndrome should
Cause of fatigue
Tiredness may be caused or due to depression or mood disorders, seasonal affective disorder, lack of exercise, poor diet with lack of adequate protein, anemia, diabetes, hepatitis, thyroid disorders, cancer, occult infections, autoimmune diseases, sleep apnea or sleep disturbances, certain mental health problems, or adrenal gland insufficiency. Teens who develop "mono," otherwise known as infectious mononucleosis, are at risk for chronic fatigue syndrome. If a full medical evaluation is completed and no major causes are found, certain supplements may be tried to increase energy levels. Women who bleed heavily each cycle should make sure they do not have iron deficiency anemia.
Supplements for fatigue
In addition to a general multivitamin, there are many supplements and herbs that help fight fatigue. Before taking supplements for fatigue, discuss with your doctor and have a full medical evaluation to rule serious medical or psychiatric causes for the fatigue. Exercise, walking, movement, dance, and yoga are great ways to boost your well being and should be tried before relying solely on taking pills. Anti fatigue supplements that may be helpful include:
B Vitamin and coenzyme complex is a good anti fatigue supplement, use a product that has about 2 to 5 times the RDA for the B vitamins rather than 50 or 100 times the RDA.
CoQ10 supplement helps reduce fatigue during physical exertion. I suggest using no more than 30 to 50 mg a a day.
Carnitine or Acetyl-l-carnitine are excellent anti fatigue supplements
Creatine muscle builder is of benefit when used in low dosages.
Pantothenic acid b vitamin
Trimethylglycine-tmg methyl donor
Ginseng herb is used in China as an anti fatigue supplement. It has also been tested with positive results in those who have felt tired due to cancer treatment such as chemotherapy and radiation.
Maca herb is an anti fatigue supplement used in South America
Rhodiola is popular among many individuals who think this herb helps improve vitality and helps with mood enhancement.
Royal jelly for more energy
Tongkat Ali herb used in small dosages. Higher amounts can lead to insomnia which can make a person tired the next day.
The right dose or combination should be explored.
Too high amounts of these anti fatigue herbs may actually cause insomnia or
restlessness which can make tiredness even worse. Only use one a time for a week
or two before combining.

Drugs Aging. 2003. L carnitine administration in elderly subjects with rapid muscle fatigue: effect on body composition, lipid profile and fatigue.
Eighty-four elderly subjects with onset of fatigue following slight physical activity were recruited to the study. Before the 30-day treatment phase, subjects were randomly assigned to two groups (matched for male/female ratio, age and body mass index). One group received carnitine 2g twice daily and the other placebo. Efficacy measures included changes in total fat mass, total muscle mass, serum triglyceride, total cholesterol, high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C), apolipoprotein (apo)A1, and apoB levels. The Wessely and Powell scale was used to evaluate physical and mental fatigue. Subjects were assessed at the beginning and end of the study period. At the end of the study, compared with placebo, the carnitine-treated patients showed significant improvements in the following parameters: total fat mass, total muscle mass, total cholesterol, LDL-C, HDL-C, triglycerides, apoA1, and apoB. Wessely and Powell scores decreased significantly by 40% (physical fatigue) and 45% (mental fatigue) in subjects taking carnitine, compared with 11% and 8%, respectively, in the placebo group. No adverse events were reported in any treatment group. Administration of carnitine to healthy elderly subjects resulted in a reduction of total fat mass, an increase of total muscle mass, and appeared to exert a favourable effect on fatigue and serum lipids.
CoQ10 for fatigue due to
Anti-fatigue effects of coenzyme Q10 during physical fatigue.
Nutrition. 2008 April. Department of Physiology, Osaka City University Graduate School of Medicine, Osaka, Japan.
This study examined the effects of coenzyme Q10 administration on physical fatigue. In a double-blinded, placebo-controlled, three crossover design, 17 healthy volunteers were randomized to oral coenzyme Q10 (100 or 300 mg/d) or placebo administration for 8 d. As a fatigue-inducing physical task, subjects performed workload trials on a bicycle ergometer at fixed workloads twice for 2 h and then rested for 4 h. Oral administration of coenzyme Q10 improved subjective fatigue sensation and physical performance during fatigue-inducing workload trials and might prevent unfavorable conditions as a result of physical fatigue.
Caffeine and fatigue - does
Effects of oral administration of caffeine and D-ribose on mental fatigue.
Nutrition. 2008. Ataka S, Tanaka M, Nozaki S, Mizuma H, Mizuno K, Tahara T, Sugino T, Shirai T, Kajimoto Y. Department of Physiology, Osaka City University Graduate School of Medicine, Osaka, Japan.
We examined the effects of administering two different candidate antifatigue substances, caffeine and D-ribose, on mental fatigue. In a double-blinded, placebo-controlled, three-way crossover design, 17 healthy volunteers were randomized to oral caffeine (200 mg/d), D-ribose (2000 mg/d), or placebo for 8 d. As fatigue-inducing mental tasks, subjects performed a 30-min Uchida-Kraepelin psychodiagnostic test and a 30-min advanced trail-making test on four occasions. During the tasks, the task performance of the caffeine group was better than that of the placebo group. However, after the fatigue-inducing tasks, although subjective perception of fatigue, motivation, or sleepiness was not significantly different, plasma branched-chain amino acid levels in the caffeine group were lower than those of the placebo group. Administration of D-ribose had no effect. Because plasma branched-chain amino acid levels are decreased by mental fatigue, these results suggest that administration of caffeine improved task performance through the enhancement of central nervous system activity without increasing the sensation of fatigue. However, further decreases in branched-chain amino acid levels indicate that caffeine might promote deeper fatigue than placebo.
Anti-fatigue effect of fresh royal jelly in mice.
J Nutr Sci Vitaminol. 2001.
We investigated the anti-fatigue effect of royal jelly, which had been stored at -20 degrees C from immediately after collection, in male Std ddY mice. The mice were accustomed to swimming in an adjustable-current swimming pool, then subjected to forced swimming five times during 2 wk, and the total swimming period until exhaustion was measured. They were separated into three groups with equal swimming capacity, which were administered royal jelly, royal jelly stored at 40 degrees C for 7 d (40-7d royal jelly), or the control solution including casein, cornstarch, and soybean oil before swimming. All mice were forced to swim for 15 min once; then the maximum swimming time to fatigue was measured after a rest period. The swimming endurance of the royal jelly group significantly increased compared with those of the other groups. The mice in the royal jelly group showed significantly decreased accumulation of serum lactate and serum ammonia and decreased depletion of muscle glycogen after swimming compared with the other groups, whereas there was no significant difference between the 40-7d RJ group and the control group in these parameters after swimming. A quantitative analysis of constituents in royal jelly showed that 5 7-kDa protein, which we previously identified as a possible freshness marker of royal jelly, was specifically degraded in royal jelly stored at 40 degrees C for 7 d, whereas the contents of various vitamins, 10-hydroxy-2-decenoic acid, and other fatty acids in RJ were unchanged. These findings suggest that royal jelly can ameliorate the physical fatigue after exercise, and this anti-fatigue effect of royal jelly in mice seems to be associated with the freshness of RJ, possibly with the content of 5 7-kDa protein.
Many people who have fatigue think it may be due to the adrenal glands. However, fatigue due to adrenal exhaustion is not as common as other reasons, particularly lack of exercise, poor diet, lack of adequate sleep, anemia, or other medical conditions. Depression is another common cause of fatigue, much more common than adrenal causes.
Are some cases genetic?
Disabling fatigue in children is not simply a symptom of depression, but appears to be an illness in its own right -- one that may be inherited. Dr. Tom A. Fowler of Cardiff University in Wales performed a twin study to investigate environmental and genetic influences on both conditions. Twin studies allow researchers to distinguish between the effects of environment and genes. While identical twins have the same environment and genes, fraternal twins share an environment but only half of one another's genetic material. So identical twins would be more likely to share conditions with a heavy genetic influence. The researchers looked at 2,398 pairs of twins between the ages of 8 and 17. Fatigue was considered disabling if it interfered with at least one aspect of school, leisure activities or relationships with family or peers, and if it required the child to rest for at least an hour daily. Fatigue was classified as short term if it lasted longer than one week, and long-term if it lasted more than a month. Both short- and long-term fatigue appeared to have genetic roots, the researchers found, while the environmental influence for short-term fatigue was stronger than the familial influence.

Fatigue Research studies
Mechanisms underlying fatigue: a voxel-based morphometric study of chronic fatigue syndrome.
BMC Neurol. 2004.
Fatigue is a crucial sensation that triggers rest, yet its underlying neuronal mechanisms remain unclear. Intense long-term fatigue is a symptom of chronic fatigue syndrome, which is used as a model to study the mechanisms underlying fatigue. Using magnetic resonance imaging, we conducted voxel-based morphometry of 16 patients and 49 age-matched healthy control subjects. We found that patients with chronic fatigue syndrome had reduced gray-matter volume in the bilateral prefrontal cortex. Within these areas, the volume reduction in the right prefrontal cortex paralleled the severity of the fatigue of the subjects. These results are consistent with previous reports of an abnormal distribution of acetyl-L-carnitine uptake, which is one of the biochemical markers of chronic fatigue syndrome, in the prefrontal cortex. Thus, the prefrontal cortex might be an important element of the neural system that regulates sensations of fatigue.
The many faces of fatigue in major depressive disorder.
nt J Neuropsychopharmacol. 2004.
Fatigue is a common complaint in the community and medical care settings. Different studies show a high comorbidity between fatigue and depressive disorder. Furthermore, fatigue is an important somatic symptom of depressive disorder and one of the main depressive presentations in primary-care medicine. Fatigue shows a slow response to antidepressant treatment and psychotherapy. Improved work performance is strongly correlated to improvement in energy. However, the assessment and treatment of fatigue in depressive disorder remains understudied. Different definitions of fatigue in depressive disorder are applied in DSM-IV and ICD-10, and depression rating scales all show a different coverage of this core depressive symptom, thereby hampering scientific research. Serotonin, norepinephrine, dopamine and histamine mediate symptoms of fatigue in depressive disorder. Although few data address the effect of antidepressants or augmentation strategies on fatigue-related symptoms, there is a pharmacological rationale for using antidepressant monotherapies.
I'm currently deployed in Iraq and was browsing on your website during some down time. I'm interested in one or two of your Energy and Fatigue supplement products that could really be of use to me over here.
As far as anti fatigue supplements, I would mention a few:
Acetyl-carnitine which has energy and mental alertness
Carnitine which has mostly physical energy and less mental
SAM-e which has energy and mood elevation
B-Complex and pantothenic acid are great options.
Ginseng, Rhodiola, Suma, and Maca are good herbs for this.
Have you heard of glucuronolactone and what it
Very little research is available regarding the influence of glucuronolactone as an anti fatigue supplement.
I went on a
diet and experienced severe fatigue. Is this common?
I've heard of a few people report this to me, it is temporary.
Are there any supplements that are advisable to offset
the fatigue associated with use of high blood pressure medications? I have heard
Co-Q10 and B complex. Any other ideas? Any ideas why these medications cause the
There are a variety of different types of blood pressure medications, diuretics, beta blockers, calcium channel blockers, etc, and they each have different side effects causing fatigue which could be due to the heart not pumping as hard or loss of electrolytes, or influence on neurotransmitter levels in the brain and body, etc. One has to take a comprehensive approach. It is not easy to predict which supplement in what dosage would be helpful without trying them one at a time.
I had some recent lab work done by my doctor b/c i have
been really tired this past year. The results came back and I have Candida and a
high level of heavy metals / Mercury in me. The dr. said that is probably why im
so tired everyday. but he moved his practice 100 miles from me so im trying to
find what supplements would be best to get rid of the chronic fatigue, the
Candida and the heavy metals / Mercury.
Fatigue is caused by many factors and some doctors who are not good clinicians will make a diagnosis of candida or metal poisoning even though chances are these are not the cause of the tiredness.
