If a product does not specify “vegetarian capsule”, then what is it made from?
These capsules are gelatin capsules sourced from either pork or beef.
Do all supplements have an NPN?
Most supplements have been issued a Natural Product Number (NPN) by Health Canada – these numbers do appear on the label. Further Natural Health Product criteria and information can be found on the Health Canada website www.hc-sc.gc.ca. Under the Food and Drugs Act, items that are considered a food – for example, protein powders and herbal teas – do not require an NPN.
Can any supplements be taken during pregnancy or while breastfeeding?
It is best to consult your Doctor, Pharmacist or Alternative Health Care Practitioner for guidance as to which supplements are safe during pregnancy or while breastfeeding.
Why are there many so types of magnesium?
Magnesium is a bit of a “diva” in the supplement world—it can’t exist on its own in a stable pill or powder form. It has to be bonded to another molecule (a “carrier”) to be stable and absorbable by your body.
The reason there are so many varieties is that the molecule magnesium is paired with changes how well it’s absorbed and where it goes in the body.
Common Forms and Their Functions
| Type | Bonded With | Common Uses |
| Magnesium Citrate | Citric Acid | Widely available and highly absorbable. Often used for general magnesium levels or as a gentle laxative at higher doses. |
| Magnesium Glycinate | Glycine (amino acid) | Known for being very easy on the stomach. It is often used for relaxation, sleep support, and muscle recovery. |
| Magnesium Malate | Malic Acid | Found naturally in fruits. It’s frequently recommended for energy support and muscle soreness. |
| Magnesium Oxide | Oxygen | Contains a high percentage of magnesium but has low “bioavailability” (absorption). Frequently used for short-term digestive relief. |
| Magnesium L-Threonate | Threonic Acid | A newer form designed specifically to cross the blood-brain barrier, often marketed for cognitive health and focus. |
| Magnesium Sulfate | Sulfur | Commonly known as Epsom Salt. Best absorbed through the skin in a soak for sore muscles. |
Why the Choice Matters
When selecting a form, it usually comes down to three factors:
- Bioavailability: Some forms (like Citrate and Glycinate) are “chelated,” meaning they are wrapped in organic acids or amino acids that your gut recognizes and absorbs easily.
- Bowel Tolerance: Magnesium naturally draws water into the intestines. Some forms (like Oxide) do this more aggressively than others, which can cause digestive upset if that isn’t the intended goal.
- Secondary Benefits: You aren’t just getting the magnesium; you’re getting the carrier. For example, malic acid is involved in the body’s energy-producing Krebs cycle, which is why Malate is the “energy” version.
A Quick Tip on Absorption
Regardless of the type, the body absorbs magnesium better in smaller, divided doses throughout the day rather than one large dose, as the kidneys are very efficient at flushing out any excess they can’t process immediately.
Are you looking for a specific benefit, like better sleep or muscle recovery, or just curious about the chemistry behind the shelf?
Can I take supplements on my own, without a doctor?
Supplements are available for sale over the counter at your local health food store or online without a prescription. Still, you should always check with your doctor before taking any product, because some supplements can cause side effects, or interact with other prescribed or over-the-counter medicines or supplements you’re already taking. It’s especially important to ask your doctor about taking a supplement if you’re pregnant or nursing, about to have surgery, or you have a health condition such as high blood pressure, heart disease, or diabetes. Also, don’t give a supplement to a child without checking with their health care provider.
What questions should I ask my doctor about taking supplements?
Ask your doctor whether you need the supplement based on your current diet and health. Also ask what benefits and risks the supplement can have, how much to take, and for how long you should take it. Make sure your doctor and pharmacist know exactly which supplements and medicines you’re taking.
