• Upper respiratory tract infections
• Difficulty concentrating
• Temporary loss of memory
• Sore throat
• Muscle and joint pain
• Intestinal problems
• Weakness
• Sore or swollen lymph nodes



Fatigue Causes

• Chronic infection
• Immune-system damage
• Low blood pressure
• Nutritional deficiencies
• Intestinal permeability
• Impaired detoxification
• Parasites and dysbiosis
• Food allergies
• Chemical sensitivities
• Neurological malfunction
• Chronic fungal infection
• Hypoglycemia
• Hypothyroidism
• Poor adrenal function
• Sleep disorders (such as apnea)
• Hormone deficiencies
• Environmental toxins (e.g., toxic metals)
• Unresolved stress
• Side effects of pharmaceutical medications
• Neurotransmitter deficiency

A double-blind, placebo-controlled human clinical trial demonstrated that ashwagandha supplementation boosted energy. The participants who took a standardized form of ashwagandha (8 percent withanolides) experienced a 79 percent increase in energy compared to those who took a placebo.

Testing Techniques

The following tests help assess possible metabolic reasons for chronic fatigue syndrome:

Immune system imbalance or disease—blood
Low blood pressure
Hormone testing (thyroid, DHEA, cortisol, testosterone, IGF-1, estrogen, progesterone)—saliva, blood, or urine
Intestinal permeability—urine
Detoxification profile—urine
Vitamin and mineral analysis (especially magnesium, B12, iron, and CoQ10)—blood
Digestive function and microbe/parasite/candida testing—stool analysis
Anemia—blood test (CBC, iron, ferritin, % saturation)
Food and environmental allergies/sensitivities—blood, electrodermal
Blood sugar balance—blood
Sleep disorder—sleep study
Heart function—EKG
Toxic metals—urine or hair analysis
