About STRESSTABS
STRESSTABS is a brand of over-the-counter (OTC) multivitamin supplements formulated to help prevent and treat vitamin and mineral deficiencies, particularly during periods of physical or mental stress. The brand is best known for combining B-complex vitamins, vitamin C, vitamin E, and iron in a single tablet to support energy metabolism, immune function, and overall well-being. Today, STRESSTABS products are sold in several countries, including the Philippines, where they are widely available in pharmacies and supermarkets. [1]
History
The STRESSTABS trademark was first registered in the United States in 1970, although the product was first used commercially in 1969. It was originally introduced as a multivitamin preparation intended for people experiencing increased nutritional demands associated with stress. Over the decades, ownership of the trademark changed through several pharmaceutical companies before becoming part of International Vitamin Corporation (IVC) in the United States. [3]
In the Philippines and several Asian markets, STRESSTABS has become one of the country’s most recognizable multivitamin brands. Distribution has evolved over time from GlaxoSmithKline (GSK) Consumer Healthcare to Haleon, following Haleon’s separation from GSK in 2022. Current Philippine products are manufactured by Pfizer Biotech Corporation in Taiwan or by local manufacturers, depending on the specific formulation. [2]

-
Physical stress

Mechanism of Action
The nutrients in STRESSTABS contribute to normal physiological functions:
-
B-complex vitamins support energy metabolism and nervous system function.
-
Vitamin C functions as an antioxidant and supports collagen formation and immune health.
-
Vitamin E protects cells from oxidative damage.
-
Iron contributes to normal red blood cell production and oxygen transport.
Together, these nutrients help maintain normal body functions when dietary intake may be insufficient. [7]
Dosage
The usual adult dosage is:
-
One tablet once daily, or as directed by a physician.
The tablets are generally taken with food to reduce stomach discomfort. [11]
Availability
STRESSTABS is classified as an over-the-counter (OTC) medicine in the Philippines. It is available in various package sizes, including blister packs and bottles, through pharmacies, supermarkets, and online retailers. [9]
Safety
Like other multivitamin supplements containing iron:
-
The recommended daily dose should not be exceeded.
-
Accidental overdose of iron-containing products can be dangerous, especially for children.
-
The product should be stored in a cool, dry place with the container tightly closed to minimize moisture exposure. [10]
Brand Positioning
STRESSTABS has long been marketed as a multivitamin supplement for people with active lifestyles or increased nutritional needs during stressful periods. In the Philippines, advertising has often emphasized support for energy, immune health, and healthy skin through antioxidants such as vitamins C and E, alongside B vitamins and iron. [8]
Trivia
-
The STRESSTABS trademark has remained active for more than 55 years, making it one of the longer-established multivitamin brands.
-
Although the name suggests relief from “stress,” the product does not directly treat psychological stress or anxiety. Instead, it supplies vitamins and minerals that help address nutritional deficiencies that may occur during periods of increased physical or mental demand. [12]
