Storage

Must be established in accordance with the requirements described in the applicable product regulations.

Products containing Cod liver oil, Fish oil or Schizochytrium oil

(except when encapsulated)

Refrigerate after opening [Source note 10].

(information for industry; not for labelling)

To be packaged in airtight container, protected from light [Source note 11].

Conditions for combined preparations

All active ingredients included in this reference may be combined across all groups, with the following restrictions:

Use or Purpose Restrictions

  • A use or purpose statement is only acceptable if at least one active ingredient associated with that statement is present at a dose at or above the minimum daily dose listed in Tables 2.1 to 2.6.

  • active ingredients which do not meet the minimum daily dose for a use or purpose statement will be considered as acceptable complementary active ingredients in product formulations.

  • For multi-ingredient products making at least one claim based on traditional use:

    • To prevent the product from being represented as a "traditional medicine," any indicated traditional use claim must refer to the specific active ingredient(s) and recognized traditional system of medicine from which the claim originates when 1) both traditional and modern claims are present or 2) when claims originate from multiple systems of traditional medicine (e.g. German chamomile is traditionally used in Herbal Medicine to help relieve restlessness and/or nervousness. Ashwagandha is traditionally used in Ayurveda to balance aggravated Vata.).

    • When ALL of the active ingredients (MIs) in the product are used within the SAME identified system of traditional medicine AND the product makes ONLY traditional claims, listing of MIs in the traditional claim(s) is not required.

Rules for sedative (soporific) ingredients (table 2.2)

If sedative ingredients (table 2.2) are combined, the sum of the percentages of the maximum daily reference dose must not exceed 120%, for all sedative ingredients in the product (including sedative ingredients supported by other source authority references such as melatonin). Note that no single ingredient can exceed 100% of its maximum daily reference dose. Please see Table 3 below for a calculation example.

Table 3. Combination Table to assess Safety of Sedative/Soporific Ingredients
Additive Indication / active ingredientse.g. Used in Herbal Medicine as a sleep aid / Maximum Daily Recommended Dose on product documentation forme.g. Used in Herbal Medicine as a sleep aid / Maximum Daily reference Reference Dosee.g. Used in Herbal Medicine as a sleep aid / Percentage of the Maximum Daily Reference Dose (%)
Eschscholzia californica (California-poppy)0.5 g3 g0.5/3 = 16.67%
Humulus lupulus (Hops)4 g6 g4/6 = 66.66%
Passiflora incarnata (Passionflower)0.5 g8 g0.5/8 = 6.25%
Sum of Percentages89.6%

The calculations are performed as follows:

  • Percentage of the Maximum Daily Reference Dose = [(Maximum Daily Recommended Dose on product documentation form) / (Maximum Daily reference Reference Dose)] x 100%

Safety assessment - Sum of Percentages:

  • In the example above, the sum of Percentages of the Maximum Daily Reference Dose is 89.6%, which is less than 120%. Safety of the combination of ingredients is therefore supported by the reference.

Rules for Caffeine

  • If a product contains caffeine from any source, it cannot contain a sedative at a therapeutic dose (table 2.2) and nervine/sedative/relaxation claims (tables 2.1, 2.2 & 2.5) are not permitted.

  • Products containing a total amount of caffeine per day that meets the minimum therapeutic dose (100 mg/day) must indicate a use or purpose associated with caffeine.

  • Products containing caffeine either synthetic, isolated or from plant materials must not:

    • indicate any uses or purpose related to healthy blood pressure or cardiovascular health at any dose (except if supported by a reference for a active ingredient providing caffeine such as green coffee bean extract).

    • indicate any uses or purpose related to the maintenance/support of good/general health at a daily dose of 40 mg or more total caffeine from all sources.

  • The maximum amount of total caffeine permitted from all ingredients in the product is 400 mg/day, and 200 mg per single dose.

  • If the total amount of caffeine provided by the combination of ingredients in the product (e.g. Yerba mate and Guarana) is equal to or higher than 40 mg per day, risk statements from the source authority Caffeine reference are required. Please see Table 5 below.

  • Additional synthetic caffeine added to Guarana and/or Yerba mate extracts must be represented as a separate active ingredient.

  • When caffeine (from any source) is combined with theacrine and/or theobromine, the sum of the percentages of the maximum daily/single reference dose must not exceed 120% for these ingredients. Note that no single ingredient can exceed 100% of its maximum daily/single reference dose. Please see table 4 below.

Table 4. Combination Table to assess safety of ingredients with a caution for cardiovascular and/or blood pressure conditions.
Additive Effect / active ingredientsIngredients which may have an impact on heart rate and/or blood pressure / Maximum Daily/ Single Recommended Dose on product documentation formIngredients which may have an impact on heart rate and/or blood pressure / Maximum Daily/ Single reference Reference DoseIngredients which may have an impact on heart rate and/or blood pressure / Percentage of the Maximum Daily/ Single Reference Dose (%)
Caffeine100 mg200 mg per single dose/400 mg per day100/200 = 50% (single dose) 100/400 = 25% (day)
Theacrine120 mg300 mg120/300 = 40%
Theobromine50 mg850 mg50/850 = 5.9%
Sum of Percentages95.9% per single dose/ 70.9% per day

See table 3 above for an example of calculations. In this example, the sum of Percentages of the Maximum reference Reference Single Dose is 95.9%, which is less than 120%. Safety of the combination of ingredients is therefore supported by the reference.

Rules for Huperzine A

When combining Huperzia serrata extract and Huperzine A (isolate or synthetic), the total quantity of Huperzine A provided by the product cannot exceed 200 micrograms per day.

Rules for Acetylcarnitine (Restrictions when this reference is combined with other references)

When combining Acetylcarnitine with L-Carnitine, the total quantity of these ingredients cannot exceed 4 grams per day and 2 grams per single dose.

Risk Information

Consult Table 5 for appropriate statements related to each active ingredient. The active ingredients in Table 5 are associated with the required numbered statements below.
