Your Daily Supplement Pack Contains:

Capsule #1: Quercetin

Quercetin helps support a normal inflammatory response and histamine balance as part of the PlexusDx Allergy Support pack, contributing to seasonal comfort and immune resilience when used with the other ingredients in the daily pack; its antioxidant activity protects cells from oxidative stress, supporting overall immune health, and the supplement provides 500 mg per serving of this well-studied plant flavonoid to deliver powerful antioxidant support that helps neutralize free radicals, supports a healthy inflammatory response and immune resilience, is commonly used for seasonal comfort by helping support normal histamine balance, and may also support cardiovascular wellness by supporting healthy blood flow and vascular function as part of an overall healthy lifestyle.

Capsule #2: Vitamin C

Vitamin C supports a healthy immune response and seasonal comfort by providing antioxidant protection and supporting collagen production for tissue integrity, and in PlexusDx Allergy Support packs it works with quercetin and omega-3s to bolster overall immune resilience during allergy season. The supplement delivers a high-potency 1,000 mg dose to support key daily functions, including collagen production for healthy skin, connective tissue, cartilage, and blood vessel integrity; as an essential nutrient, it must be obtained from diet or supplements and also supports healthy bones and gums, normal red blood cell formation, and antioxidant defenses that help protect cells from oxidative stress, playing an important role in immune support and overall stress resilience as part of a balanced wellness routine. This clean formula contains no common allergens and is made without dairy, wheat, soy, peanuts, tree nuts, eggs, shellfish, sesame, or fish.†

Capsule #3: Omega 3

Omega-3 provides 750 mg of essential omega-3 fatty acids per serving, including EPA and DHA, to support a healthy inflammatory response and the integrity of cell membranes—key for overall cellular health and contributing to immune and seasonal comfort within the PlexusDx Allergy Support packs; when paired with quercetin and vitamin C, it helps support overall immune resilience and cellular function during allergy season. The formula is molecularly distilled to remove PCBs, dioxins, pesticides, and heavy metals and to reduce oxidation for clean, reliable quality, and because your body can’t synthesize omega-3s, supplementation supports heart health and healthy cholesterol within the normal range, while also supporting brain, liver, muscle, and joint function.
