How Much DHA? Most of us get DHA from fish, but many fish are contaminated with mercury, PCBs and other toxins. Taking DHA as a supplement is the safest way to be sure. To drive sufficient DHA into our cell membranes we need supplements that are much higher in DHA than EPA. It may be possible that consuming more EPA than DHA could block DHA benefits. For those who are healthy, Dr. Kidd and other experts suggest 500mg per day. Pregnant or lactating women 1000mg per day. Individuals with memory, mood or behavior problems 1000-- 3000 mg/day. Babies likely need at least 315 mg/day for the first 6 months. Children will benefit from intakes 1000-1500 mg per day, preferably under supervision from a health practitioner. Phosphatidyl Serine (PS): The Most Proven Brain Booster Of all the natural brain enhancing nutrients, PS (Phospha- tidyl Serine) is the most proven based on clinical trials. PS is a phospholipid and very safe and highly effective. Ex- tensively researched – some 30 double-blind clinical trials, more than 100 human studies and thousands of biochem- ical studies. Like DHA, PS is naturally built into our biochemistry and is more concentrated in the brain than other organs. PS is also concentrated in breast milk, a sign it is important for brain health. PS is now accepted worldwide as a supplement for memory, learning and cognition. PS can also help anxi- ety, assisting in coping with stress and increase positive moods. PS: Proven From Double-Blind Clin- ical Trials • Improvement of memory, learning and other cognitive functions in people who are substantially impaired, compared to others in their age group. • Improvement of behavior, sociability (social interest) and activities of daily living, in people with major memory problems. • Improvement of brain vitality. The brain's energy tends to dwindle when things are going wrong, and in clinical studies PS increased the levels of energy in the brain tissues. • Helpful for stress management, as tested using emotional or physical challenges. • Improvement of negative mood and easing of anxiety, in young and elderly people. • Improvement of attention and behavior in children with attention and behavior problems. • In a PET imaging study, subjects after taking PS showed improved energy production and utilization throughout the brain. PS: Vital Building Block for Brain Cells PS is found in all cells, because its phospholipid structure is required for building the cell membrane systems that hold cells together and do most of their biochemical work. PS: Essential For the Brain's Connections Nerve cell membranes rely on PS for its electrical charac- ter. The connections (synapses) are the functional units of information transfer in the brain. The healthy human brain has between 100 and 1000 trillion synapses, all of which rely on PS for their normal functions. PS: Supports Energy Generation by The Mitochondria PS is deeply involved in how all our cells, including the nerve cells, make energy. They get at least 90 percent of their energy from their mitochondria. Their main job is to
