ProHealth’s Think Clear™ contains the top four brain and memory enhancement nutrients in one unique formula. This complex formula enhances circulation and oxygen flow to the brain to promote optimal cell health, as well supports information transmission from cell to cell. Our Think Clear™ combines the omega-3 fatty acid DHA, ginkgo biloba, vinpocetine and Huperzine A, each of which have been clinically shown to support brain health and reduce risk of age-related memory loss.

Ginkgo Biloba: Ginkgo biloba is a powerful antioxidant best known for its ability to enhance circulation throughout the body and brain. It has the capacity to squeeze through the narrowest of blood vessels to increase the supply of oxygen to the brain and other parts of the body.

Huperzine A: Promotes enhanced mental function. Huperzine A helps maintain levels of acetylcholine, a brain nutrient that plays a major role in cognitive activity. By promoting healthy acetylcholine levels, memory health is maximized. In addition, huperzine A supports the nervous system's role in transmitting information from cell to cell.

DHA (Docosahexaenoic Acid): An omega-3 fatty acid, DHA is a major building block of brain and retinal (eye) tissue that plays a role in blood vessel health and the inflammation response.

Most Complete Cognitive Formula. Compared to other products that focus on one or two ingredients for brain-functioning support, ProHealth’s Think Clear™ utilizes four top-rated nutrients for brain and memory health to effectively support cognitive function including, ginkgo biloba, Huperzine A, DHA and vinpocetine.

High-Quality Source of DHA. Compared to other products that source DHA from fish oil, we use the highest-quality source of DHA from algea oil.

Quality Manufacturing Practices. All of our products are manufactured in an FDA-registered, GMP-certified facility.

Third-Party Tested in the USA. Every batch is third-party tested in US laboratories to ensure the highest quality, purity and potency. Certificates of Analysis are available.

"Love this product! It does exactly what the label says "think clear". Before I started taking it years ago - I had fuzzy thinking. I try never to run out. I have to take 2/day (instead of the recommended 1) but I'm so glad this product exists. Thank you!"

Better than ginkgo bloba

I began using “Think Clear” after using ginko bloba for a number of years. At 75 my memory was not what it should be. After taking “Think Clear” for a couple of months I could see my memory and recall were much quicker.

Mischa G.
Wonderful thank you

I think I'm thinking clearer now I can't tell but I think they work

Gary G.

Think Clear™ (60 medium veggie capsules) by ProHealth

Janel L.
It really helps!

It really helps my whole mental acuity, my concentration and memory.

Anna M.L.
I have used these for more than 10 years.

I began having cognitive difficulties, particularly problems with short term memory, remembering words in the middle of a sentence, calculating etc. After I started on Think Clear my cognition improved significantly, so I have used them daily for more than 10 years. I will not risk to be without them, so I always stock up on them as much as I can afford. So I highly recommend this product for cognitive problems.
