Choosing the correct tampon absorbency and style is important for both comfort and health. Using the wrong product can lead to leaks, discomfort, or potentially increase the risk of Toxic Shock Syndrome (TSS). Effective menstrual management requires understanding standardized absorbency levels and matching them to your flow. The primary goal is to find the lowest absorbency that still provides adequate protection.
Understanding Absorbency Levels
The “size” of a tampon primarily refers to its absorbency capacity, not necessarily its physical length or diameter. Absorbency levels are standardized across the industry, often regulated by bodies like the Food and Drug Administration (FDA), to ensure consumers can compare products from different brands. This consistency is achieved by measuring how many grams of fluid a tampon can absorb using a standard laboratory test.
The standard absorbency levels are categorized into five main terms. A Light absorbency tampon is rated to hold 6 grams of fluid or less, which is suited for the final days of a period or spotting. Regular tampons absorb between 6 and 9 grams of fluid and are appropriate for a moderate flow that many people experience through the middle of their cycle.
Super absorbency tampons are designed for a heavier flow, capable of holding between 9 and 12 grams of fluid. For significantly heavy flow days, there are Super Plus tampons, which absorb 12 to 15 grams, and Ultra absorbency, which handles the maximum range of 15 to 18 grams of fluid. These standardized terms ensure that a Super tampon from one manufacturer has a comparable absorption capacity to a Super tampon from another.
Matching Absorbency to Your Flow
The safest practice is to use the lowest absorbency level that fully manages your menstrual flow. Your flow changes throughout your period, meaning you will likely need to use different absorbency levels on different days. It is common for the flow to be heaviest on the first few days and then taper off toward the end.
If your tampon leaks before the four-hour mark, the absorbency is too low, and you should move up to the next level. Conversely, if you remove a tampon after four to eight hours and a significant portion of the material is still dry or white, the absorbency is likely too high. Using a product with an unnecessarily high absorbency can cause vaginal dryness and make removal uncomfortable or painful because the dry fibers may cause friction.
A tampon must be changed every four to eight hours, and never worn for more than eight hours. If you can comfortably wear a single tampon for the full eight hours, consider decreasing the absorbency level to minimize the risk of TSS. Monitoring the frequency of changes and the saturation upon removal are the best ways to self-assess the correct absorbency.
Considering Physical Fit and Comfort
While absorbency is the main factor in protection, physical characteristics influence comfort during insertion and wear. Tampons come in various designs, including those with applicators and those without. Applicator tampons, typically made of plastic or cardboard, are often preferred by new users as they make insertion easier and more hygienic by guiding the tampon into place.
Plastic applicators have a smoother finish and rounded tip, which many users find more comfortable than cardboard applicators. Some applicators are compact, meaning they telescope out to full size just before use, offering a more discreet and portable option. Non-applicator tampons, inserted using a clean finger, allow for greater control over placement and create less waste.
The shape of the tampon also affects comfort; some are slender, while others are contoured or flared. Although the physical diameter does not determine the absorbency rating, a narrower tampon can be easier to insert, especially for those with a lighter flow. Trying different applicator materials and tampon shapes helps ensure the most comfortable fit for individual anatomy.
