Key Benefits and Actions*

  • Soy-free formula
  • May help support cognitive health
  • May help support healthy cellular membranes
  • May help support healthy liver and muscle tissues

Optimal PC Liquid by Seeking Health provides 5,200 mg of phospholipids from non-GMO sunflower oil (containing about 12% (w/w) phosphatidylcholine) without the common use of soy. Although phospholipids can be found in a wide variety of foods such as meat, eggs, and soy, some individuals including vegans and vegetarians may benefit from supplementation. It may also become more difficult for choline to pass through the blood-brain barrier with age.*

Phosphatidylcholine (PC) may help provide the building blocks of healthy cell membranes which may help maintain healthy brain function. PC is a precursor to acetylcholine which is a major neurotransmitter in both the brain and the peripheral nervous system. It is also important for cardiovascular support through the maintenance of lipid metabolism. PC may help support healthy liver function by aiding in maintaining healthy liver cells and normal processing of fat and cholesterol in the liver. This may help maintain the normal detoxifying capacity of the liver. PC may help replenish choline in the blood after intense exercise, supporting healthy energy levels and normal muscle recovery.*

Optimal PC also contains two other types of phospholipids, phosphatidylethanolamine and phosphatidylinositol. Phosphatidylethanolamine is a key building block of cell membrane bilayers. It can be transformed into PC, but this phospholipid may also play a role in the assembly of membrane proteins. It may help support the normal orientation of enzymes in the inner membrane. Phosphatidylinositol is present in all tissues and cell types, especially brain tissue. Derivatives of this phospholipid serve as messenger molecules with the nervous system.*

For a lower dose of this soy-free phospholipid blend in an easy-to-swallow softgel, consider our Optimal PC Softgels. If you are looking for phosphatidylserine, a compound derived from phospholipids in sunflower lecithin, consider our Phosphatidyl Serine.*

Good for energy

People, Just Nutribullet 1 - 3 teaspoon of it with a Tablespoon of Hemp Oil and a cup of water for a minute until it becomes completely smooth and foamy. A blender isn't fast enough to do it. Then, add a cup of berries. Jazz up with 2 T of cocoa and 1 T of cinnamon or cocoa nubs! You can't even taste the PC and you've got lots of extra nutrition. And energy!

Stopped taking this

I did not feel well after taking the suggested dose, and the consistency is extremely off putting. It is literally the thickest goop you can imagine without being a hard solid. How do people stomach this? I just swallowed the clump.

Learned of it from "Dirty Genes"

You sent me your great book, "Dirty Genes", I see myself in it. I bought this because of the book, now I understand why some supplements don't make me feel better. I can use this, watching how I respond and using the pulse method, I feel more energy and less aches. You are a great company.
