Essential for men's virility and testosterone production, Vitamin D is widely deficient and declines with age. Evidence makes it pretty clear that Vitamin D is tied to healthy T-levels in men. The only question is, how does it work? Nobody knows (yet), but some possible bio-activities and pathways include: Vitamin D Receptors (VDRs) are present in the testes, prostate … [Read more...]
DHEA for Testosterone
DHEA is a precursor to both testosterone and estrogen, but it's surrounded by question marks and a Big Warning* DHEA is a type of hormone made by the adrenal glands and the testes. It is unclear whether DHEA has any impact on circulating T-levels, but it does seem to have some links to testosterone: Needed for testosterone synthesis, DHEA is a nutritional precursor … [Read more...]
Caffeine as a Nootropic
It's not a true nootropic, but caffeine is a reliable, fast-acting stimulant that boosts alertness. Caffeine is more of a brain-stimulating drug than a brain-nourishing nootropic. It delivers its energizing effects to both body and mind by: Suppressing "soothing" brain chemicals. Caffeine blocks a neurotransmitter that signals for end-of-day winding down and … [Read more...]
Acetyl-L-Carnitine as a Nootropic
Acetyl-L-Carnitine may help with the depression and memory loss that sometimes affects geriatric populations. Acetyl-L-Carnitine (also called ALC, LAC or ALCAR) is an amino acid that supports health across many body systems. Within the brain specifically, ALCAR has been suggested to promote: Neurotransmitters. ALCAR is a necessary ingredient for acetylcholine … [Read more...]
Huperzine-A as a Nootropic
Huperzine-A is an alkaloid that is rapidly absorbed into the brain, where it may fight mental degeneration. Lab-synthesized from the Chinese Club Moss plant (Huperzia serrata), Huperzine-A (sometimes simply called Hup-A) is believed to function as a nootropic by: Boosting acetylcholine. It neutralizes an enzyme that destroys this key cognition neurotransmitter. … [Read more...]
