Positive experiences
“ALCAR is great. Great energy burst. I find it takes a few hours to kick in though.”
“ALCAR , magnesium bisglycinate and zinc bisglycinate and non-iodized sea salt have completely changed my life.”
“I can easily sit for 12+ straight and focus. I thought Pterostilbene was insane but this is another beast completely.”
“This supplement improves focus and mental clarity. When taken by itself brain fog is completely removed and I feel sharp as a knife.”
“Carnitine has a noticeable effect and makes you feel like your Addy tolerance has gone down. I'd recommend trying it.”
“Acetyl L Carnetine, ALCAR, it helps me with brain fog and IIRC helps other items pass the blood brain barrier.”
Negative and mixed experiences
“I took Acetyl L-Carnatine twice a day for a couple of weeks. It made me fell depressed and sad. First day I stopped the L-Canatine the blues evaporated.”
“I started taking mitochondrial supplements like pqq and alcar, and they helped me immensely at first but for the past few months, anything I take makes me feel worse.”
“I took it for a week and felt nothing but that was after I started NALT.”
“After two weeks of taking I started feeling amazing, the depression was almost no existent anymore. But now its back again.”
“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.”
