ProdromeNeuro contains the plasmalogen building blocks for neurons that make up gray matter. Neurons are cells that process and transmit information in the body. These plasmalogens commonly become deficient with age.

ProdromeGlia contains the plasmalogen building blocks for glial cells that make up white matter. Glia are cells that surround, support, and protect neurons. These plasmalogens commonly decrease with inflammation.

The ProdromeScan Blood Test will tell you if you are deficient in the ProdromeNeuro plasmalogens, the ProdromeGlia plasmalogens, or both. Without taking the ProdromeScan Blood Test, you can try either product or we suggest alternating between ProdromeNeuro and ProdromeGlia each day (for example take ProdromeNeuro the first day and then ProdromeGlia the next day and keep alternating). Another popular option is to take ProdromeNeuro in the morning, and ProdromeGlia in the evening.

The plasmalogen products offered on Amazon are purified from animal sources and have a very low concentration of plasmalogens: One product has 0.5mg of plasmalogen per 1 capsule (and 30mg of plasmalogen per bottle) and the other product on Amazon has 4mg of plasmalogen per one capsule (and 240mg per bottle). Compare that to our product which has 900mg per serving and 27,000mg per bottle! Our product has more plasmalogens in just one serving than the others have in the entire bottle.

You can take ProdromeNeuro, ProdromeGlia, and ProdromeGTA at any time of day. They can be taken with or without food. They can be taken with any other supplements.

The recommended dose is 900mg each day. Some individuals prefer taking a loading dose of 2-4x the daily dose for 1-2 weeks. It is recommended to continue taking the plasmalogen supplement every day.
