immune 24 hour

Several listings use the wording “Non-Drowsy” (or “non drowsy”) and explicitly state “24-hour relief,” which signals daytime, non-sedating relief in those products.

The 24-hour relief items list symptom relief for sneezing, runny nose, itchy or watery eyes, and itchy nose or throat. Common triggers named include pollen (trees, grass, ragweed), dust, mold, and pet dander. One nasal spray listing also mentions relief of nasal congestion.

Results include a vitamin C immune supplement marketed for 24-hour immune support and several allergy medicines—both oral antihistamine tablets and nasal sprays—that state 24-hour relief.

Many allergy products are intended for once-daily use. The mushroom/algae supplement specifies two capsules daily, and at least one antihistamine tablet listing suggests taking a dose at night to provide coverage the next day.
