A few things I have read - I wonder if people have noticed a difference taking aspartame out of their diet and adding Mucuna Prurients. I personally avoid artificial sweeteners but have not tried Mucuna.
"Aspartame is a synthetic, laboratory concocted, genetically modified, sugar-replacement nightmare that causes depression and anxiety, not to mention irritable moods, migraines and insomnia. It elevates aspartic acid and phenylalanine in the brain, preventing the synthesis and release of neurotransmitters, norepinephrine, serotonin and dopamine. I
"Mucuna Pruriens, which contains a natural compound called L-Dopa – the precursor to the human neurotransmitter dopamine. It works to stimulate the pituitary gland to increase it’s production, without nicotine, chemicals or prescription medications. There are no side effects from this natural supplement. The uses for Mucuna are multi-faceted, including increased libido, increased fertility, leaner muscle mass, reduced aging, increased bone density, and boosted energy levels."
