Swanson FAQs

Find the answers to questions you may have regarding Swanson Health Products. If you can't find what you're looking for, please contact us here.

Swanson MFG (Manufacture Date)

Swanson products are often marked with a Manufacture (MFG) date rather than an Expiry (EXP) date. Unless specified by an expiry date, products are considered stable at full potency for two years from the MFG date. Exceptions to this include liquids and probiotics which are considered stable for one year from the MFG date.

Manufacture Date

The Manufacture Date printed on the label represents the date upon which the product was produced and is your assurance of quality and freshness. Often, on a dark coloured bottle, the MFG date will be printed on the bottom of the bottle. All Swanson products are produced by approved Good Manufacturing Practices (GMP) compliant manufacturers to meet specified standards for quality and stability.

Swanson will continue to test and study their products to assure they meet the expected shelf-life (in most cases two years from the date of manufacturer). This change in label dating is due to a modification of regulatory requirements and does not represent a change in the quality of Swanson brand products.

Rest assured that there has been no change to the ingredient selection or manufacturing procedures and Swanson brand products continue to meet and exceed the most stringent quality control standards. Swanson will continue to require that their manufacturers develop and formulate products to maintain their quality for the expected timeframe (two years for most products, one year for probiotics and some liquid products).

This change in product dating applies only to Swanson brand supplements and does not include food items or topical or cosmetic products (creams, lotions, shampoo, etc.)

Colour Variations

Please note, all supplements, especially herbs, can and do have colour variations from lot to lot, and even from jar to jar.

Freshness Packs

Swanson Health Products have introduced a new 'freshness pack' within a number of their products, designed to reduce the buildup of moisture and maintain freshness for longer.

On very rare occasions this pack has been known to open during transit or in extreme conditions.

If you find your product contains a freshness pack that has been damaged or the contents spilled out, then please contact us immediately. The supplements may still be okay to consume, however consuming the contents of the freshness pack can be harmful to your health. We therefore recommend that you send the item back to us, so we can send out a replacement as soon as possible.

Consumption Tips

Please know that Swanson Capsules can be opened and the contents may be dissolved in water or added to other food or beverages. We would not suggest this with a softgel as you cannot remove all of the contents to get the full dosage.

Animal Testing

We are pleased to inform you that Swanson do not test their products on animals nor do their manufacturers. They use ingredients that are already known to be safe, however cannot guarantee a specific ingredient has not been tested on an animal at some point in history.

What does "Standardised" mean?

Herbal supplements are often available in two major forms, whole herb and standardised.

Whole herbs have a variable level of active components. Potency will vary with growing conditions and time of harvest. Whole herb products are generally the mildest form of a herb, and often have higher amounts recommended for suggested servings.

Standardised herbs have a set percentage of active components that is consistent from batch to batch. Standardised herbs are not only more consistent than whole herbs, but more potent as well because the manufacturer can incorporate a higher percentage of active components during processing than the concentrations found in whole herbs.

Recommended serving sizes are often smaller in terms of weight such as milligrams and in total number of capsules or tablets suggested per day.

Different Types of Probiotic

Swanson do not test for a strain number on most of their probiotics with their contract manufacturers, only the strain type. Most often a specific strain number is under a patent and is a trademarked ingredient. Since Swanson do not have an agreement in place with the company that owns the patent and/or trademark, they cannot legally provide this information.

Heavy Metals

All Swanson products are tested for heavy metals. The heavy metal limits are listed below.

Lead: 2.75 µg/maximum daily dose
Arsenic: 10 µg/maximum daily dose
Cadmium: 4.1 µg/maximum daily dose
Mercury: 0.3 µg(organic)/maximum daily dose
3 µg(inorganic)/maximum daily dose

The maximum daily dose must be based on the maximum daily dose on product label.  Swanson's manufacturers are required (in accordance with cGMP) to quality control test each batch and provide certificate of analysis. Swanson also do quality control testing and retain samples of each batch of product. Additionally, depending on manufacturers track record as far as quality of production, random batches are tested by 3rd party laboratories as well. Swanson's standing with being audited and in line with cGMP is the customers verification that their products are compliant with the GMP requirements for quality control testing on the products.
