Your Needs are Important

All of us at Carlson Laboratories are keenly aware of what the health-conscious consumer wants in a nutritional supplement. Although nutritional supplements are chosen primarily for their active ingredients, the other non-active ingredients (excipients) needed to make the tablet, capsule or liquid are just as important to those concerned about their health. For this reason, excipients are only used in Carlson products when absolutely necessary and in the smallest amounts possible. When they are needed, our choice is based on safety, naturalness and purity.

Carlson Excipients


Holds the ingredients in a tablet together. One of three types of binders are used as required: Plant fiber known as cellulose, acacia gum from the stem of the Acacia tree or brazil wax from the leaves of a palm tree.


Fills out the size and shape of a tablet or capsule making it practical to produce and convenient for the consumer to use. Plant cellulose or microcrystalline cellulose (pure plant filler) is the filler of choice in Carlson tablets or hard gelatin capsules. Soybean oil, sunflower oil or safflower oil is commonly used in soft gelatin capsules. Medium Chain Triglycerides (MCTs) from coconut and palm oil are used in liquid vitamin D drops.


Expands when wet causing the tablet to break apart in the digestive tract releasing the nutrients for absorption. Croscarmellose sodium serves this purpose in many Carlson tablets.


Prevents ingredients from clumping together and from sticking to the tablet punches or capsule filler. Common minerals, silica and forms of vegetable oils known as magnesium stearate and stearic acid are the most often used lubricants in Carlson tablets or hard gelatin capsules.


Coatings protect tablet ingredients from deterioration by moisture in the air and make large tablets easier to swallow. For most coated tablets, a cellulose (plant fiber) film coating is used which is free of sugar and potential allergy-causing substances. Occasionally, a naturally occurring resin isolated from tree bark called food glaze or pharmaceutical glaze is used to coat tablets as a timed-release agent.


Added to make the nutrients more palatable in chewable tablets or liquids. Sweeteners found naturally in fruits such as fructose, and zero-calorie sugar alcohols such as sorbitol and xylitol are typically chosen.

Flavors and Colors

Added to improve the taste and/or appearance of a formulation. We use only natural flavors and natural colors when necessary.
