StressKiller® Super-nutrient Supplements

A carefully balanced blend of 10 super nutrients (vitamins, minerals, adaptogens, and amino acids) for CALM and FOCUS. 

Why kill stress?  Because you want to enjoy life.  But also because “medical research estimates as much as 90 percent of illness and disease is stress-related" (according to Clemson University and the USDA).




L-Theanine "significantly increases activity in the alpha frequency band [of the brain] which indicates that it relaxes the mind without inducing drowsiness" (National Institutes of Health abstract, Asia Pacific Journal of Clinical Nutrition, "L-theanine, a natural constituent in tea, and its effect on mental state")

"L-theanine has demonstrated benefit for patients diagnosed with anxiety by increasing levels of dopamine and GABA in the brain. It also improved test performance without the agitation caused by caffeine.  We conclude that L-Theanine is a safe and effective way to help treat anxiety and improve concentration." (Cleveland Clinic)


"Acutely stressful situations can disrupt behavior and deplete brain norepinephrine and dopamine... Tyrosine significantly decreased symptoms, adverse moods, and performance impairments in subjects" (Brain Research Bulletin, "Treatment with tyrosine, a neurotransmitter precursor, reduces environmental stress in humans," by US Army Research Institute for Environmental Medicine)


"Supplementation with tyrosine may, under operational circumstances characterized by psychological and physical stress, reduce the effects of stress and fatigue on cognitive task performance" (Brain Research Bulletin, "Tyrosine improves cognitive performance and reduces blood pressure in cadets after one week of a combat training course," by members of the Dept. of Clinical Neuropsychology, Vrije University, Amsterdam and the Royal Netherlands Army Dept. of Behavioral Sciences)

"Tyrosine appears to provide important benefits in mitigating severe stress effects on mood and cognition" (USAREIM: Physiological Research for the Warfighter)

"Tyrosine supplements have reduced the adverse effects of hypoxia, cold, body negative pressure, and psychological stress" (Committee on Military Nutrition Research, Institute of Medicine, National Academy of Sciences)


"Ashwagandha supplementation was associated with a statistically significant reduction in the Hamilton Anxiety Rating Scale (P = .040) and a near-significant reduction in the Depression, Anxiety, and Stress Scale -21 (P = .096). Ashwagandha intake was also associated with greater reductions in morning cortisol (P < .001), and DHEA-S (P = .004) compared with the placebo." (Medicine - study lead by College of Science, Health, Engineering, and Education (SHEE), Murdoch University, Perth)

Vitamin B-12, B-6, and Folate (folic acid)

“'At the end of the three-month period, those in the Vitamin B group reported much lower levels of work stress than they did at the beginning of the trial,' he said.  'In fact, participants experienced an almost 20 per cent improvement in stress levels'...  Professor Stough said that the results were perhaps unsurprising, given the important role Vitamin B plays in cognitive function... 'By lowering stress, we also lower the risk of health problems such as cardiovascular disease, depression and anxiety.'" (Centre for Human Psychopharmacology, Swinburne University of Technology)

"Vitamin B-12 and other B vitamins play a role in producing brain chemicals that affect mood and other brain functions.  Low levels of B-12 and other B vitamins such as vitamin B-6 and folate may be linked to depression" (Mayo Clinic)

"Studies show that a deficiency of vitamin B12 can produce abnormal neurological and psychiatric symptoms, including anemia, fatigue, muscle weakness, dementia, and mood disturbances" (Mayo Clinic)


"... Magnesium, which keeps cortisol (a stress hormone) levels low. Low magnesium levels can also cause headaches and fatigue, so maintaining a healthy level can prevent these common stress symptoms" (Cleveland Clinic)

"Stress, whether physical... or emotional (i.e. pain, anxiety, excitement or depression) and dyspnea as in asthma increases need for Mg." (Journal of the American College of Nutrition, "Consequences of magnesium deficiency on the enhancement of stress reactions," by M.S. Seelig, Dept. of Nutrition, UNC Chapel Hill)

Vitamin C

"The link between vitamin C and mood may seem surprising, but it's not so far-fetched.  People who have vitamin C deficiency often feel fatigued or depressed.  Plus, some studies show that vitamin C can have mood-elevating effects" (Mayo Clinic)

"Intake of this vitamin can help lower the levels of cortisol, a stress hormone, and blood pressure during high-anxiety situations" (UCLA Integrative Medicine)

"Ascorbic acid helps fight infections, heal wounds, and keep tissues healthy. It is an antioxidant that helps prevent cell damage caused by free radicals.  Vitamin C cannot be produced or stored by humans and must be obtained in the diet.  It must be taken in every day." (NIH National Cancer Institute)
