Menstrual tampons are personal hygiene products categorized by their absorbency level. The “Ultra” designation represents the highest absorbency rating available, intended for the heaviest flow days of a menstrual cycle. Understanding the Ultra size involves grasping its functional capacity, which is strictly defined by regulatory standards. This maximum absorbency product provides protection for individuals who experience very heavy menstrual bleeding.
Physical Dimensions of Ultra Tampons
Ultra tampons are physically larger than other absorbency levels, though the increase in size is often less dramatic than expected. The physical dimensions of the compressed core are not uniform across all brands, unlike the standardized absorbency rating. For example, a non-applicator Ultra tampon core may be approximately 5.1 centimeters (2 inches) in length and 1.7 centimeters (0.7 inches) in diameter before expansion.
The final physical size is also affected by the product’s design, such as whether it uses an applicator. Applicator tampons are longer and wider before use, but the absorbent material itself is compressed. The key functional difference is the density and type of absorbent material, which allows for greater fluid capacity. The physical size difference between a Super Plus and an Ultra tampon is marginal compared to the increase in fluid absorption capability.
Absorbency Rating Standards
The term “Ultra” is a standardized absorbency rating established by the Food and Drug Administration (FDA). This rating defines the maximum fluid a tampon must hold under laboratory conditions. The Ultra absorbency level is strictly defined as absorbing between 15 and 18 grams of fluid.
This capacity is measured using the standardized scientific Syngyna test. The Syngyna method uses a device that mimics the internal vaginal environment by applying specific pressure and temperature. A saline solution, which simulates menstrual fluid, is introduced until the tampon is fully saturated and leaks. This regulated scale provides consumers with a reliable way to compare the functional capacity of different products.
Selecting the Appropriate Absorbency
Ultra tampons are intended for individuals with an extremely heavy menstrual flow, particularly during the heaviest days of their cycle. Health guidance advises using the lowest absorbency level necessary to manage the flow. Choosing an Ultra tampon when a lower absorbency product suffices can lead to vaginal dryness or discomfort upon removal.
Using a higher-absorbency tampon than needed may increase the risk of Toxic Shock Syndrome (TSS), a rare bacterial infection. A highly absorbent tampon left in place for an extended period can become a favorable environment for the bacteria that cause TSS. Ultra absorbency is appropriate if a Super Plus tampon becomes saturated and requires changing in under four hours. If an Ultra tampon is not fully saturated after four to eight hours of wear, switch to a lower absorbency level for the next use. Tampons should never be worn for more than eight hours, regardless of the absorbency level.
