FAQ for Mteryti®


What is Mteryti®
Mteryti® is a MultiVitamin/MultiMineral Supplement Tablet specially formulated for use in women at least 2-3 months prior to conception, throughout pregnancy and during breastfeeding. It is recommended for use under the supervision of a healthcare professional.
What is the recommended dosage schedule for Mteryti®?
Women are to take one pink (a.m.) and one blue (p.m.) Mteryti® tablet daily, beginning at least 2‐3 months prior to conception, throughout pregnancy and during breastfeeding.

One pink (a.m.) tablet should be taken every morning on an empty stomach, one hour before breakfast, with a glass of water. One blue (p.m.) tablet should be taken with a glass of water close to the evening meal (before or after), i.e. within one hour of the evening meal.
Should Mteryti® be taken with or without food?
Mteryti® pink (a.m.) tablet should be taken on an empty stomach with a glass of water. Patient should avoid food and beverages for one (1) hour after taking the pink (a.m.) tablet to optimize iron absorption.

Mteryti® blue (p.m.) tablet should be taken within one (1) hour of the evening meal to optimize calcium absorption. For example, if a woman eats dinner at 6 p.m., it is recommended that she take her blue (p.m.) Mteryti®tablet any time between 5 p.m. and 7 p.m., even with her evening meal.
Can the pink (a.m.) and the blue (p.m.) tablets be taken at the same time?
We do not recommend taking Mteryti® pink (a.m.) and blue (p.m.) tablets at the same time. The purpose of taking the two tablets at different times is to optimize the absorption of key nutrients (i.e. folic acid, iron, calcium). As calcium can prevent iron from being properly absorbed, Mteryti® separates iron in the morning tablet and calcium in the evening tablet to allow for optimal iron absorption.
Can Mteryti® tablets be crushed/split/chewed?
We do not have absorption or stability data available on split, crushed or chewed tablets. Splitting, crushing or chewing the tablets is not recommended.
Why take Mteryti® preconceptionally?
If you are planning a pregnancy, it is important to consume a sufficient amount of folic acid in order to have adequate levels of folate at the time when the neural tube normally closes (which starts approximately 21 days post‐conception and is usually complete by 28 days; around the time a woman may first recognize her pregnancy by a missed menstrual period).
Why do you use this 2‐step approach?
In Mteryti®, calcium is contained in the blue (p.m.) tablet and iron in the pink (a.m.) tablet. The purpose of taking two tablets at different times is:
  • to prevent calcium from inibiting the absorption of iron*
  • to allow vitamin C to facilitate the absorption of iron*
In addition, folic acid has been shown to bind iron. By taking these components in separate tablets, this potential interaction may be avoided.*
How should Mteryti® be taken when it is concurrently taken with levothyroxine hormone (thyroid medication)?
Absorption of thyroid medication could be reduced if taken at the same time as iron or calcium supplements. Therefore, for women taking levothyroxine hormone in the morning on an empty stomach, it is recommended to take the Mteryti® pink (a.m.) tablet at least four (4) hours apart to optimise the absorption of levothyroxine hormone. [In this case, it is preferable to stay on an empty stomach at least 2 hours before taking the pink (a.m.) tablet and 1 hour after to ensure iron absorption optimization.]

For women taking levothyroxine hormone at bedtime, it is recommended to take the Mteryti® blue (p.m.) tablet at least four (4) hours apart to optimise the absorption of levothyroxine hormone. [It should be kept in mind that it is recommended that the blue (p.m.) tablet be taken within 1 hour of an evening meal.]
If you cannot take the pink (a.m.) tablet on an empty stomach, can you reverse the order by taking the blue (p.m.) tablet in the morning and the pink tablet at night with Mteryti®?
We do not recommend this dosage schedule. The Mteryti® dosage schedule is based on scientific knowledge. The body best absorbs iron on an empty stomach and the calcium carbonate contained in the blue (p.m.) tablet is best absorbed when taken with food.

If for any reason you can’t take the pink (a.m.) tablet one hour before your breakfast (e.g. on thyroid medication, feels nauseated in the morning), the pink (a.m.) tablet may be taken two (2) hours or more after breakfast. Following administration of the pink (a.m.) tablet a wait of one (1) additional hour is recommended before eating or drinking in order to optimize the absorption of iron. It is preferable to have at least 4 hours in between the intake of the tablets.
What if you forget to take Mteryti® pink (a.m.) or blue (p.m.) tablet?
When a dose has been missed, it should be taken as soon as possible: one pink (a.m.) and one blue (p.m.) tablets should be taken within a 24 hour period. It is recommended that Mteryti® pink (a.m.) and blue (p.m.) tablets be taken at least four (4) hours apart in order to optimize the absorption of nutrients.

If you realize you forgot to take one or both Mteryti® tablet on the next day, you should not try to catch up. An occasional omission should not pose a problem. It is important that only one pink (a.m.) tablet and one blue (p.m.) tablet be taken per day.

The dosing schedule should then continue as directed by your healthcare professional.
Does Mteryti® contain other vitamins and minerals beside folic acid?
Yes. Mteryti® was designed to ensure pregnant women get the vitamins and minerals generally needed during pregnancy. 

It is important to note that taking vitamin and mineral supplements during pregnancy does not eliminate the need for a complete and balanced diet.
Do Mteryti® and Mteryti® Folic 5 have the same active ingredients?
Yes, other than the amount of folic acid in the blue/dark blue (p.m.) tablet, active ingredients are the same.
Why is folic acid in the evening tablet?
Mteryti® provides folic acid in the evening tablet to ensure that a woman will continue to receive her daily requirement of folic acid in the rare event that she is unable to tolerate the level of iron found in the morning tablet for a short period of time. Concurrent ingestion of folic acid and iron may result in the formation of stable complexes. Folic acid is provided separately from iron so this potential interaction may be avoided.*
Why is there no DHA (Docosahexaenoic acid) in Mteryti®?
Because the benefits of DHA (Docosahexaenoic acid) during pregnancy have not been proven, Dietary Reference Intakes (DRIs) have not been established in the United States. However, many expert groups suggest 200 mg of DHA intake daily. This may be achieved in a number of ways but is ideally derived by eating 1 to 2 portions of fish per week. Approximately 1 g of EPA/DHA can be obtained from 100 g (3.5 oz) of oily fish. Because of the risk of mercury exposure, pregnant women should avoid shark, king mackerel, swordfish, and tilefish.

In short, pregnant women should consume at least 2 meals of fish per week to achieve a DHA goal of 200 mg/day. Supplementation with DHA and EPA cannot be definitively recommended during pregnancy because of lack of data. However, evidence of risk is low. If you or the patient feel that DHA is appropriate both the animal and plant forms are available OTC at a very reasonable price.
Why do you have "Zinc" logo on the package?
The International Zinc Association states that zinc is a trace‐element especially important during pregnancy, for the growing fetus whose cells are rapidly dividing. Zinc also helps to avoid congenital abnormalities and pre‐term delivery. Since our goal was to develop a prenatal/postpartum multivitamin that meets the highest standards, we made sure to meet their recommendations with regard to the inclusion of zinc.
Is Mteryti® suitable for people with food constraints?
Yes. Both are Lactose, gluten and tartrazine free and have received the Kosher, Kosher for Passover, and Halal certifications.
Is Mteryti® certified Kosher/Halal?
Yes. Mteryti® has received the Kosher, Kosher for Passover, and Halal certifications. Our suppliers confirmed that the ingredients sourced for this formulation of Mteryti® do not contain pork, bovine and chicken by‐products.
Is Mteryti® suitable for Passover?
Yes, Mteryti® is now certified Chometz Free. To being certified Kosher, the Kashruth Council of Canada has acknowledged that Mteryti® is also in full compliance with Passover requirements.
What are the contraindications for Mteryti®?
Mteryti® is contraindicated in women with known hypersensitivity to any of the ingredients in the formulation or component of the container.
Is it safe to take Mteryti® passed the expiration date?
Regulatory agencies such as FDA and Health Canada fix a certain expiration date from the time Mteryti® is manufactured based on the stability data on this product. After that date we do not know if it will remain safe and effective. Therefore, we do not recommend that Mteryti® be used after the expiration date. However, it can safely be taken until the expiration date inclusively.
Why does Mteryti® have an iron warning?
Because Mteryti® contains iron, the U.S. Food and Drug Administration (FDA) regulations require, as a precautionary measure, that an iron warning statement appears on the labeling of iron-containing dietary supplements and drugs in solid oral dosage form (e.g., tablets, capsules, or caplets).

If you suspect an overdose or seek additional overdose information, you should contact a poison control center at 1-800-222-1222.

KEEP YOUR SUPPLEMENTS STORED IN A SAFE PLACE OUT OF THE REACH OF YOUNG CHILDREN.
What are the side effects associated with Mteryti®?
The most common adverse reactions associated with vitamin‐mineral supplements are gastro‐intestinal symptoms such as constipation, diarrhea, nausea and gastric irritation. At high doses (e.g. 15 mg/day) folic acid has been associated on rare occasion with various gastrointestinal symptoms and central nervous system (CNS) effects such as sleep disturbances, difficulty concentrating, irritability, hyperactivity, excitement, mental depression, confusion, and impaired judgment.
What should I do if I experience an adverse event?
Always tell your healthcare professional about any adverse events. You are encouraged to report negative side effects to the FDA. Visit www.fda.gov/medwatch or call 1-800-FDA-1088.

Important Risk Information

Warning: Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately.

Women who consume healthful diets with adequate folate may reduce their risk of having a child with birth defects of the brain or spinal cord. Public health authorities recommend that women consume 0.4 mg folic acid daily from fortified foods or dietary supplements, or both, to reduce the risk of neural tube defects. The safe upper limit of daily intake value for folic acid is 1,000 mcg (1 mg). This product exceeds the DV (1,000 mcg) of folic acid. Folate intake should not exceed 250% of the DV (1,000 mcg). However, Mteryti® and Mteryti® folic 5 tablets may be appropriate for some women under a healthcare professional's supervision.
