Thorne Magnesium Comparison: Which Formula Is Right for You?

Quick answer: Thorne offers three magnesium products at Cunningham Clinic: Thorne Magnesium Bisglycinate (powder, $52), Thorne Magnesium Bisglycinate Travel Packs (stick packs, $47), and Thorne Magnesium Glycinate (capsules, $26). All three deliver 200 mg of chelated, highly absorbable magnesium per serving to support sleep, muscle relaxation, and heart health; the main differences are format, portability, and price.

If you’ve ever dealt with restless nights, muscle cramps, or that afternoon energy slump, magnesium deficiency might be part of the picture. Magnesium is involved in more than 600 enzymatic reactions in the body, yet getting enough of it from diet alone is harder than most people realize. That’s where a high-quality supplement comes in — and few brands are as trusted in the wellness space as Thorne.

This guide breaks down what magnesium actually does for your body, why the form of magnesium matters, and how the three Thorne magnesium products available at the Cunningham Clinic store compare so you can choose the one that fits your lifestyle.

Why Does Your Body Need Magnesium?

Magnesium is an essential mineral, meaning your body can’t produce it on its own — it has to come from food or supplementation. According to the National Institutes of Health Office of Dietary Supplements, magnesium helps regulate muscle and nerve function, blood sugar levels, blood pressure, and even the production of protein, bone, and DNA.

Here’s a closer look at what magnesium does for you:

• Supports restful sleep. Magnesium helps regulate neurotransmitters that calm the nervous system, making it easier to wind down at night.
• Relaxes muscles. It plays a key role in muscle contraction and relaxation, which is why it’s popular among athletes and anyone dealing with cramps or tension.
• Promotes heart health. Magnesium is essential for the heart’s electrical activity, helping maintain a healthy rhythm and normal blood pressure.
• Strengthens bones. Research shows that people with higher magnesium intake tend to have higher bone mineral density, an important factor in reducing fracture risk.
• Supports steady energy. As a cofactor in cellular energy production, magnesium helps keep your energy levels consistent throughout the day.

Who Is Most at Risk of Magnesium Deficiency?

Despite its importance, many people don’t get enough magnesium. The NIH notes that certain groups are especially likely to run low, including older adults, people with gastrointestinal conditions like Crohn’s disease or celiac disease, and those managing type 2 diabetes. Early signs of deficiency can include fatigue, loss of appetite, and muscle cramping, while more significant deficiency may contribute to sleep disruption and irregular heart rhythm.

This is where a well-formulated magnesium supplement can help close the gap — but not all forms of magnesium are created equal.

Why Absorption (Bioavailability) Matters

Not every magnesium supplement is absorbed the same way. Some common forms, like magnesium oxide, are cheap but poorly absorbed and often cause digestive discomfort. Others, like magnesium citrate, absorb reasonably well but can have a laxative effect at higher doses.

This is where magnesium bisglycinate (also called magnesium glycinate) stands out. This form binds magnesium to the amino acid glycine, creating a true chelate that “envelopes” the mineral. The result is a gentler, more bioavailable form of magnesium that’s easier on the stomach and less likely to cause the digestive side effects associated with lower-quality formulas. Glycine itself is also a calming neurotransmitter, which is part of why this form is often recommended for evening use.

All three Thorne magnesium products available at Cunningham Clinic use this superior bisglycinate form, so the real differences between them come down to format and use case rather than absorption quality.

Meet the Thorne Magnesium Lineup

Thorne has earned a reputation as one of the most trusted names in nutraceuticals. It’s the only supplement manufacturer to collaborate with Mayo Clinic on wellness research and content, and it’s a proud partner of 11 U.S. Olympic teams, with formulas chosen by more than 100 professional sports organizations. Thorne manufactures every product with rigorous quality control, and its bisglycinate formulas are NSF Certified for Sport®, meaning each batch is tested for label accuracy and screened for more than 200 substances banned by major athletic organizations.

Here’s how the three magnesium options on the Cunningham Clinic Thorne shop compare.

Thorne Magnesium Bisglycinate (Powder)

Thorne Magnesium Bisglycinate is a lightly sweetened powder — flavored with monk fruit rather than sugar — designed to mix easily into water or your favorite beverage. Each scoop delivers 200 mg of magnesium bisglycinate, and each container includes 60 servings.

• Best for: Anyone who prefers a powder over swallowing capsules, or who wants a large supply that lasts.
• NSF Certified for Sport®: Yes
• Price: $52.00 (regularly $58.99)

Thorne Magnesium Bisglycinate Travel Packs (30 Sticks)

For anyone who’s on the move, the Thorne Magnesium Bisglycinate Travel Packs offer the same formula as the powder jar, portioned into single-serve stick packs. Each stick delivers 200 mg (48% DV) of magnesium bisglycinate and mixes in seconds with 8 ounces of water.

• Best for: Travelers, gym bags, desk drawers, or anyone who wants grab-and-go convenience without sacrificing quality.
• NSF Certified for Sport®: Yes
• Price: $47.00 (regularly $58.99)

Choose this option if you like the powder jar but need something more portable for a busy, on-the-go lifestyle.

Thorne Magnesium Glycinate (90 Capsules)

If you’d rather skip the mixing altogether, Thorne Magnesium Glycinate delivers the same well-absorbed magnesium bisglycinate chelate in a simple vegetarian capsule. It’s free of gluten, dairy, and soy, and uses minimal, purpose-driven ingredients rather than fillers like magnesium oxide or citrate.

• Best for: Anyone who prefers capsules over powders and wants the most budget-friendly entry point into Thorne’s magnesium line.
• Price: $26.00 (regularly $48.99)

How to Choose the Right Thorne Magnesium for You

With all three products using the same high-quality bisglycinate form, your decision really comes down to lifestyle and preference:

• Choose the powder if you like mixing supplements into your daily routine and want the most servings per purchase.
• Choose the travel packs if portability matters more than cost—perfect for frequent travelers or athletes who need NSF-certified purity on the go.
• Choose the capsules if you want the simplest, most budget-friendly way to start magnesium supplementation.

For general wellness support, Thorne recommends mixing one scoop or stick pack with at least 8 ounces of water once or twice daily, or taking capsules as directed on the label. That said, individual needs vary based on diet, health history, and current medications. Because magnesium can interact with certain medications, including some antibiotics and diuretics, it’s always a good idea to talk with your healthcare provider before starting any new supplement — especially if you have kidney concerns or take prescription medications regularly.

Frequently Asked Questions

What is the difference between magnesium bisglycinate and magnesium glycinate?
They’re essentially the same compound. “Bisglycinate” is the more technically accurate term because two glycine molecules are bound to each magnesium ion, but many brands use the terms interchangeably. Both offer superior absorption and a gentler effect on the digestive system compared to magnesium oxide or citrate.

How much does Thorne magnesium cost?
Pricing at Cunningham Clinic ranges from $26.00 for the 90-capsule Magnesium Glycinate to $52.00 for the Magnesium Bisglycinate powder, with the travel packs priced at $47.00. All three are currently discounted from their regular list prices.

Is Thorne magnesium safe to take daily?
Thorne’s magnesium products are formulated for daily use and are free from major allergens like gluten, dairy, and soy. However, magnesium supplements can interact with certain medications, so consult your healthcare provider before adding any new supplement to your routine, especially if you have existing health conditions.

Which Thorne magnesium product is best for sleep?
All three products use the same magnesium bisglycinate form, which is commonly used for evening supplementation because of its calming properties. The powder and travel packs may appeal to those who like an evening wind-down ritual, while the capsules offer a quick, no-mixing-required option before bed.

What’s the difference between the Thorne magnesium powder and the travel packs?
The formula is identical — both deliver 200 mg of magnesium bisglycinate per serving. The main difference is packaging: the powder comes in a 60-serving jar for home use, while the travel packs offer 30 single-serve sticks for convenience on the go.
