4 absorbable forms of magnesium
For magnesium to be effective, it has to be absorbed. By taking the best forms of magnesium that are absorbable—orotate, citrate, glycinate, and taurinate—in the correct amounts, you are not only helping to support your heart, but you are ensuring the health of your entire body. Core to Dr. Stephen Sinatra's philosophy is that everyone should supplement with 400 mg per day, which is what you get in every daily dose.
Benefits your heart, blood pressure and even mood!
Many consider magnesium to be an “unsung hero,” acting as one of your body’s most critical nutrients. In addition to cardiovascular support, it’s involved in over 300 enzymatic reactions throughout your body! This includes the production of adenosine triphosphate (ATP—the body’s basic fuel for every cell in your body).
Easy-to-take capsules and gentler on your stomach
A lot of multivitamin formulas use only magnesium oxide, but very little of it is actually absorbed into the body, which can have a potent laxative effect on your colon. The same goes for Milk of Magnesia. The 4 forms of magnesium Dr. Sinatra included are easy to swallow and much gentler on your stomach.
Why you need magnesium
While you can get magnesium in your diet, it’s likely you’re not getting enough, especially since today’s soil quality is leading to nutrient-deficiency in the foods we consume. And, things like age, stress, poor diet, and environmental pollutants can deplete magnesium.
Signs you may not be getting enough magnesium
Many people are magnesium deficient either due to medical conditions or poor diet and/or other lifestyle habits. But how do you know if your magnesium levels are low? Here a few signs you may not be getting enough magnesium:
- Increased anxiousness
- Reduced concentration
- Muscle fatigue
- Poor appetite
- Poor sleep
- Decreased mood
- Low energy levels
With Magnesium Broad Spectrum Complex, you get a full doctor-recommended dose of 400 mg in just 2 servings a day.
This “unsung hero” does wonders for your heart health!
The 4 forms of magnesium in every dose help support healthy blood flow, normal blood pressure levels, and healthy arteries. And, provide support for one of the top markers of heart health—inflammation, including C-Reactive Protein (CRP).
Healthy bones, less muscle fatigue and more
For your muscles and bones to be at their best, they need more strength and less muscle fatigue after strenuous exercise. That’s why ensuring your body is getting enough magnesium is crucial, as well as making sure it’s being absorbed.1

A better mood and positive outlook on life!
We could all use some relief from stress and anxiousness, and magnesium helps with this. And, promotes a positive mood and outlook. All of which can help better prepare you for a good night of rest.
Boosts & balances magnesium
Broad-spectrum formula boosts and balances your body’s magnesium levels, which are critical to the healthy function of your entire body. And, helps shuttle calcium and potassium (essential electrolytes) into and out of your cells.

Science and Quality
Magnesium is an essential nutrient that is necessary for many metabolic activities, including ATP production and promoting energy and physical health in those struggling with low mood.
Like calcium, magnesium is readily available through food. Good dietary sources include dairy products, fish, meat, and seafood. It is also abundant in many fruits and vegetables, and whole grains and herbs. Yet, most Americans do not consume enough of this important mineral, and deficiencies are common, particularly in the elderly.1
Cardiovascular health
- Magnesium helps support the cardiovascular system.1, 2
- Epidemiological studies suggests that high dietary intake of magnesium is associated with healthy blood pressure.3, 4, 5
- Supplementation with magnesium (400 to 600 mg per day) has demonstrated significant effects in promoting and maintaining normal blood pressure values.6, 7, 8, 9
Bone health in Men
- Magnesium supports bone health and parameters of bone formation.
- Magnesium helps maintain bone health.
- A randomized, parallel, controlled trial with 50 healthy young adult men, consuming 364.5 mg of magnesium showed that magnesium consumption resulted in significant support of bone formation biomarkers, including osteocalcin.10
- Another study involving 139 healthy women showed that consuming 300 mg of magnesium significantly supported physical mobility and function.11

What makes Magnesium Broad-Spectrum Complex different from other magnesium supplements?
Read More
Rather than relying on a single magnesium source, this broad-spectrum formula is designed to provide comprehensive support for multiple areas of health. Magnesium plays an essential role in hundreds of biochemical processes throughout the body and is particularly important for cardiovascular function, healthy circulation, muscle function, and bone health. The combination of multiple forms reflects Dr. Sinatra's long-standing belief that a broad-spectrum magnesium formula offers more complete support than a single-form product alone.
Why does this formula contain five different forms of magnesium?
Read More
Magnesium citrate and glycinate are popular choices among consumers seeking highly utilized forms of magnesium. Magnesium taurinate combines magnesium with taurine, a nutrient known for its importance in cardiovascular health. Magnesium orotate has long been used in heart-focused nutritional protocols, while magnesium oxide helps contribute to overall magnesium intake.
By combining these forms, Magnesium Broad-Spectrum Complex delivers a more comprehensive approach than products containing only one type of magnesium. This strategy aligns with Dr. Sinatra's decades-long focus on nutritional support for cardiovascular wellness and healthy aging.

What is the difference between magnesium glycinate and magnesium citrate?
Read More
Rather than asking consumers to choose between them, Dr. Sinatra's formula includes both forms in a comprehensive blend. Magnesium Broad-Spectrum Complex combines magnesium glycinate, magnesium citrate, magnesium taurinate, magnesium orotate, and magnesium oxide in one formula.
This broad-spectrum approach helps provide more complete magnesium support than relying on a single form alone. It also allows consumers to benefit from the unique characteristics of multiple forms of magnesium while supporting cardiovascular health, circulation, and muscle function.

When combined with magnesium citrate, glycinate, orotate, and oxide, magnesium taurinate helps create a comprehensive formula designed to support cardiovascular health, circulation, healthy blood pressure levels already within the normal range, and overall wellness.
What is magnesium orotate and what makes it unique?
Read More
Rather than relying on magnesium orotate alone, Dr. Sinatra chose to combine it with four additional forms of magnesium to create a more complete formula. This broad-spectrum strategy helps provide a wider range of magnesium support than single-form products.
By including magnesium orotate alongside magnesium citrate, glycinate, taurinate, and oxide, Magnesium Broad-Spectrum Complex reflects Dr. Sinatra's belief that cardiovascular wellness benefits from a comprehensive nutritional approach rather than reliance on a single nutrient form.
