Formula Purposes & Benefits

CircuGuard is formulated to support healthy blood flow and reduce clotting factors. Designed using the mechanisms of action found in Triple Anticoagulant Therapy (1), CircuGuard’s all-natural Organic Turmeric Root Extract, White Willow Extract, and Dan Shen ingredients help support a health cardiovascular and circulatory system in people recovering from the adverse effects of Long Covid, microclots, and platelet hyperactivation.
Beet Root extract has been added to the CircuGuard formula to boost energy and increase stamina by promoting better oxygen delivery to muscles and tissues, thereby combatting the most common Long Covid symptom – fatigue.

The active ingredient in Black Pepper Root extract, piperine, boosts the bioavailability and duration of action of Turmeric. (6)

The ingredients in CircuGuard are also powerful anti-inflammatory (White Willow extract, Turmeric, Dan Shen, and Beet Root extract) and antioxidant (Turmeric, Dan Shen, and Beet Root extract) agents.

Our CircuGuard formula is completely unique and innovative formula to support people with Long Covid on their road to recovery.



Formula Ingredient Deck

Benefits Of Each Ingredient

Organic Turmeric Root Extract

(Curcumin 95%)

 ●       The curcumin active ingredient in Turmeric acts as an anticoagulant, helping to prevent the formation of blood clots. (2)

 ●       The mechanism of action for curcumin as an anticoagulant is inhibition of activated Factor X (FXa) and inhibition of thrombin. (2)

 ●       Turmeric is a powerful anti-inflammatory and antioxidant. (2)

White Willow Extract

(std. 15% Salicin)

 ●       White Willow Extract acts as a platelet activation inhibitor, preventing platelets from contributing to clot formation. (3)

 ●       Salicin, the active ingredient in White Willow Extract, inhibits platelet activation by inhibiting the COX-1 enzyme (mechanism of action). (3)

 ●       White Willow Extract, and it’s salicin active ingredient, also act as an anti-inflammatory by inhibiting the COX-2 enzyme. (3)

Dan Shen Extract (10:1)

 ●       Dan Shen acts as a platelet activation inhibitor, preventing platelets from contributing to clot formation. (4)

 ●       Salvianolic Acids A and B, the active ingredients in Dan Shen, inhibit platelet activation by inhibiting the P2Y1 and P2Y12 G-Protein Couples Receptors (mechanism of action). (4)

 ●       Salvianolic Acids A and B are also known to be powerful antioxidants and anti-inflammatory agents. (4)

Organic Beet Root Extract

●       Beet Root extract is a natural means of boosting nitric oxide (NO) production in the body. (5)

 ●       An increase in nitric oxide (NO) helps boost oxygen delivery to the muscles and tissues, which can potentially help alleviate fatigue in Long Covid. (6)

 ●       Nitric oxide (NO) also acts as a platelet activation inhibitor, potentially inhibiting platelet hyperactivation in Long Covid. (6)

 ●       Beet Root extract and the bioactive ingredients it contains are known to be potent antioxidants and anti-inflammatory agents. (6)

Black Pepper Fruit Extract 95%

(Piper nigrum)

●       The active ingredient in Black Pepper Root extract, piperine, boosts the bioavailability and duration of action of Turmeric. (6)

●       Piperine inhibits the metabolism of the curcumin active ingredient in Turmeric, increasing both the concentration of curcumin and its duration of action. (6)

Clearing up my brain fog

I've been taking CircuGuard for almost a month now and within the first few days, I just felt kind of miraculously clear-headed. Like the last remaining cognitive fog I had from Long COVID was lifted. This feeling has remained. I started with one pill a day and I am up to four pills per day with no side effects at all. I will take for a few more months to see if the smalls clots I have under my fingernails resolve. I'll update my review if they do. Of all of the many supplements I've tried during my four years of Long COVID, this was the only one where I actually felt a difference. It's definitely worth a try. P.S. my functional medicine doctor reviewed the ingredients and he liked all of them.

I love that it's an all natural alternative with less risks!

I'm a LONG long hauler, and finally found a place to get my blood tested at just over 3 years in - yup: it's full of microclots! The idea of blood thinners and triple anticoagulant therapy concerned me, it feels very high risk living at home alone in an already unstable condition. I'm SO grateful for this all natural alternative, and the cost is WAY lower than the Rx combo my doctors recommended! I'm on my 3rd week of taking CircuGuard daily, with ZERO side effects or reactions, and FINALLY feeling hopeful for a full recovery. I've followed the microclots research, followed Keith's research to create this supplement, and feel confident this is the KEY to getting my life back!

CircuGuard is making all of the difference!

My wife has struggled with Long COVID for nearly two years, and CircuGuard is the only thing that has helped with her fatigue, brain fog, and joint pain! She is finally starting to recover and is getting her life back!
