What people say about ALCAR and focus
“I can easily sit for 12+ straight and focus. I thought Pterostilbene was insane but this is another beast completely.”
“I've personally experienced heightened anxiety as well as insomnia (though the insomnia is fairly easily remedied by making sure you take the pill in the morning).”
“I eventually increased the Noopept NALT ALCAR dose to 2 capsules 3x daily for a week before running out and nothing.”
“This supplement improves focus and mental clarity. When taken by itself brain fog is completely removed and I feel sharp as a knife.”
