Description

C ComplX™: Vitamin C + Herbal Flavonoids*


90 vegetarian capsules


When your body is under increased oxidative demand, whether from environmental exposure, immune challenges, or an active cleansing protocol, its antioxidant reserves are working harder than usual. Vitamin C and bioflavonoids don't just share a label, they share a natural partnership. In whole foods like acerola and citrus, these compounds occur together for a reason: bioflavonoids help the body properly absorb and use vitamin C, and the two work together to support a healthy antioxidant response. C ComplX™ delivers 600 mg of vitamin C in two complementary forms alongside a standardized blend of citrus bioflavonoids, rutin, and quercetin, formulated to mirror how vitamin C is actually found in nature. Built for sensitive individuals navigating complex health journeys.*


May be increased temporarily for intensive nutritional support.*

Why Choose C ComplX™?

Built for More Than Everyday Wellness

Your body isn't dealing with everyday stress. Whether you're supporting your immune system, working through a cleanse protocol, or managing histamine responses, your nutritional demands are higher. C ComplX™ was formulated for that reality.

  • Cleanse Protocol

    Cleanse Protocol

    Vitamin C supports healthy GI motility and regularity, making it a natural fit for those working through an active cleanse or detox protocol.*
  • Immune Challenges

    Immune Challenges

    For those navigating ongoing immune demands, vitamin C and quercetin work together to support a balanced, healthy immune response.*
  • Histamine Help

    Histamine Help

    Quercetin is well recognized for its role in supporting healthy mast cell function and a balanced histamine response, particularly relevant for overactive systems stemming from environmental stressors.*
  • Sensitive Individuals

    Sensitive Individuals

    Two forms of vitamin C paired with bioflavonoids means better absorption with no unnecessary fillers, built for those who react to what's in most supplements.*
What's Inside

Premium Ingredients, Quality Sourced.

Every capsule is packed with clinically studied, bioavailable nutrients. No fillers, no fluff.

  • Vitamin C
    600 mg

    Ascorbic Acid and Acerola Extract

    Delivers vitamin C in two complementary forms. Ascorbic acid provides a reliable, well-absorbed baseline dose, while acerola fruit extract (standardized to 25% vitamin C) adds naturally occurring plant co-factors that support optimal use at the cellular level. Together they support healthy immune function and the body's normal antioxidant activity.*

  • Acerola Extract
    200 mg

    Malpighia glabra L.

    One of nature's most concentrated fruit sources of vitamin C. Standardized to 25% vitamin C content, acerola brings more than isolated ascorbic acid — it contributes naturally occurring phytonutrients that complement the body's use of vitamin C in immune and antioxidant pathways.*

  • Citrus Bioflavonoids
    100 mg

    Standardized to 50% hesperidin

    A key bioflavonoid found in the pith and peel of citrus fruit. Bioflavonoids help the body absorb and use vitamin C more efficiently, and support a healthy response to oxidative stress. Hesperidin in particular is well studied for its role in vascular integrity and immune modulation.*

  • Rutin
    50 mg

    A plant-derived bioflavonoid found naturally in buckwheat, citrus peel, and apple skin. Rutin supports antioxidant status and works synergistically with vitamin C to support the integrity of capillary and connective tissue, both of which can come under stress during periods of immune challenge or environmental exposure.*

  • Quercetin
    50 mg

    A widely researched bioflavonoid known for its role in supporting a healthy immune and inflammatory response. Quercetin supports mast cell regulation and helps modulate how the immune system responds to environmental triggers — making it particularly relevant for those dealing with mold-related sensitivities and PANS/PANDAS.*

Frequently Asked Questions

Everything you need to know about C ComplX™ to start your wellness journey.

Can C ComplX™ be used as part of a cleanse or parasite protocol?

Yes. Vitamin C supports healthy GI motility and regularity, and serving sizes may be increased temporarily for intensive nutritional support. C ComplX™ is included in the Alight Parasite Kit for this reason. Always follow the guidance of your healthcare practitioner when adjusting serving sizes.*

How do I take C ComplX™ and how long does one bottle last?

The recommended dose is 1 capsule daily with or without meals, or as directed by your healthcare practitioner. Each bottle contains 90 capsules, providing a 90-day supply at the standard dose. Serving size may be increased temporarily for intensive nutritional support.

Can I open the capsule and mix it with food or liquid?

Yes. The capsule can be opened and the contents mixed into water, juice, or soft foods. Keep in mind that ascorbic acid has a tart, slightly sour taste at higher amounts, so mixing with something flavored works best. This is also a convenient option for children or those who have difficulty swallowing capsules.

What makes C ComplX™ different from a regular vitamin C supplement?

Most vitamin C supplements deliver isolated ascorbic acid and stop there. C ComplX™ delivers vitamin C in two complementary forms alongside citrus bioflavonoids, rutin, and quercetin, the plant compounds that naturally accompany vitamin C in whole foods and support its absorption and antioxidant activity in the body.*

Can I take C ComplX™ with other supplements or medications?

C ComplX™ is formulated with naturally derived ingredients, however we always recommend consulting your healthcare provider before starting any new supplement, particularly if you are taking blood thinners, chemotherapy agents, or immunosuppressants, as high-dose vitamin C may interact with certain medications.

Is C ComplX™ appropriate for children?

C ComplX™ may be appropriate for children following Clark's Rule dosing adjustments. We recommend consulting your healthcare practitioner before giving any new supplement to a child, particularly those navigating PANS/PANDAS or other complex immune conditions.

Is C ComplX™ third-party tested?

Yes. Every batch undergoes rigorous third-party laboratory testing for heavy metals, microbial contaminants, and potency verification. Our manufacturing facility is NSF-certified and follows strict current Good Manufacturing Practice (cGMP) guidelines enforced by the FDA.

Is it vegan / gluten-free / soy-free / dairy-free?

Yes. C ComplX™ is vegan, and every batch is tested free of gluten and soy. The ingredients themselves are dairy-free, however C ComplX™ is manufactured in a facility that also processes dairy, so we cannot guarantee it is free of dairy cross-contact. If you have a severe dairy allergy or sensitivity, please consult your healthcare provider before use.
