What is Viridian's Cognitive Complex?

Viridian’s Cognitive Complex is an advanced combination of effective neuro-protective and antioxidant rich nutrients. Thisformulaisspecificallytargetedtosupportbrainfunctionandassist cognition (mental processing) through reduced oxidative stress, improved cellular fluidity, neurotransmitter response, and sense of relaxation.


PS is the major phospholipid in the brain and is embedded in cell membranes, and along with other phospholipids, makes up the basic structural components of the cell membrane. Thesemembranephospholipidsplayanimportantroleincelltocell communication, membrane fluidity, and transfer of biochemical messages into the cell, which trigger cellular responses. Numerous clinical trials have established that PS exerts significant benefit for cognitive functioning, especially those functions which tend to decline with age, including memory, learning, vocabulary skills, and concentration.

It is suggested that PS affects hypothalamic release of corticotropin-releasing factor, an activator of the hypothalamic-pituitary-adrenal axis in response to stress. This may provide some insight into the effect of PS on depression, as hypercortisolism is a common finding in depression.


ALC is derived from the amino acid l-carnitine and is an active antioxidant protecting the cell membranes of neurons against free radical attacks. In addition, ALC promotes phospholipid metabolism and enhances brain energy production. ALC facilitates the uptake of acetyl CoA into the mitochondria during fatty acid oxidation, enhances acetylcholine production, and stimulates protein and membrane phospholipid synthesis. Studies have shown ALC may be of benefit in treating Alzheimer’s disease, depression in the elderly, ischemia and reperfusion of the brain, and cognitive impairment due to alcoholism.


Alpha lipoic acid is a sulphur-containing antioxidant, playing key roles in the production of cellular energy and acts uniquely as a potent antioxidant in protecting against both fat and water soluble free radicals. ALA also extends and enhances the effect of other antioxidants, which are used to defend the body against free radical damage. Recent research reveals that administrating mitochondrial nutrients, such as ALA and its derivatives in combination with other mitochondrial nutrients e.g. CoQ10 to aged people and patients suffering from neurodegenerative diseases, may be an effective strategy for improving mitochondrial and cognitive dysfunction.

What is L-THEANINE ?

L-theanine is a unique amino acid present almost exclusively in the tea plant (Camellia sinensis). In the brain, L-theanine increases dopamine and serotonin production. L- theanine increases alpha-brain wave activity, a sign of induced relaxation. A small Japanese study of university students showed oral L-theanine administration of 200 mg led to increased alpha- brain waves and a subjective sense of relaxation. Theanine administration caused a dose- dependent relaxed, yet alert, state of mind without sedation, beginning approximately 40 minutes after oral dosing. Green tea is often used as a relaxing beverage, although it can contain more caffeine than coffee. The anine appears to counteract the stimulant effect of caffeine to some degree.

What is Co ENZYME Q10?

Coenzyme Q10, also known as ubiquinone, is a naturally occurring substance and an essential component of the mitochondria – the energy producing unit within our cells. CoQ10 is involved in the production of ATP, the energy molecule. The benefits of CoQ10 centre around energy production and for its benefits as an antioxidant. Recent research suggests that it is also beneficial in neurological disorders as it has been discovered that Parkinson’s disease patients have decreased levels of CoQ10 within platelet mitochondria.


the superfood combination of spirulina, alfalfa, and bilberry provide an abundance of wholefood micronutrients and phytochemical antioxidants to provide extra synergy and nutritional intake. Viridian choose to use the green food blend as a natural ‘filler’, rather than synthetic excipients, to ensure the product is 100% active.


Take two capsules daily or as recommended by a practitioner.
Effective intakes of phosphatidylserine range from 100mg per day (for children and for adult brain maintenance) through 300mg / day for memory loss, and up to 600mg /day for mood enhancement. Acetyl-L-carnitine is usually given orally in tablet or capsule form with dosage ranging from 1-3 grams daily, in divided doses. If administered intravenously, the dosage is usually 1500-2000 mg.
ALC is considered safe at these dosages and without incidence of significant side effects, even with long-term (one year) administration.
Oral therapeutic dosages of alpha-lipoic can be as much as 1800mg daily.
For relaxation, 200 mg L-theanine can be taken 1-3 times daily.

What can Viridian's Cognitive Complex be used for?

Cognitive conditions such as declining memory (dementias), poor attention, poor concentration and attention span. Neurological disorders such as Alzheimer’s disease, Parkinson’s disease, peripheral neuropathies, oxidative stress, elevated cortisol associated with stress, agitation and confusion (brain fog). Mitochondrial disorders (mitochondropathies).

Known contraindications

Not recommended for use during pregnancy


L-theanine increases the activity of doxorubicin, idarubicin, pirarubicin, cisplatin, and irinotecan in tumor cells.
CoQ10 is structurally similar to vitamin K and has been reported to interact with warfarin.

Useful links

Use along with nutritional oils such as Organic Flax Seed oil support cognitive effects.
B vitamins and cognitive influencing herbs such as Rhodiola rosea may also be beneficial.

Note: improving and maintaining the structure of the neuronal cells and reducing free radical damage, can optimise brain and nervous system functioning and may help slow the ageing process of these cells/tissues.
