Why Did Unbox Health Rate Our Magnesium Bisglycinate an A+?

The supplement market today is huge. Walk into a store or browse online, and you’ll find hundreds of options, each promising better health, better energy, better sleep. But here’s the truth: not every supplement delivers on its claims. Many contain hidden fillers, misleading labels, or weak formulations that do little for your health.

This is why platforms like Unbox Health exist: to cut through the noise and tell consumers what’s actually worth their trust. And when Unbox Health awarded our Magnesium Bisglycinate an A+ rating, it wasn’t just luck. It was the result of careful formulation, honest labeling, and a commitment to purity.

Who Is Unbox Health?

Unbox Health is an independent platform dedicated to helping people make informed decisions about supplements and health products. Their mission is simple: to cut through the noise of marketing claims and uncover what really works.

Unlike regular online reviews (which are often biased or sponsored), Unbox Health follows a transparent and evidence-based evaluation system.

Their ratings are designed to answer two key questions:

1. Does this supplement contain exactly what it says it does?
2. Is it safe from harmful or toxic substances?

The answers come from two core criteria:

• Label Accuracy Score (LAS)
• Non-Toxicity Score (NTS)

What Do These Criteria Mean?

1. Label Accuracy Score (LAS)

This measures whether a supplement is truthful and reliable in its labeling.

• Does the product contain the nutrient form listed on the label?
• Is the dosage accurate and within the effective therapeutic range?
• Are there hidden or undisclosed ingredients?
• Is the brand transparent about sourcing and formulation?

A high LAS means you’re getting exactly what’s promised, nothing less, nothing misleading.

2. Non-Toxicity Score (NTS)

This measures whether the supplement is free from harmful contaminants and unnecessary additives.

For iThrive Essentials Magnesium Bisglycinate, the NTS was calculated using a combination of heavy-metal non-toxicity values, including:

• Lead Non-Toxicity: 1.00
• Arsenic Non-Toxicity: 1.00
• Cadmium Non-Toxicity: 1.00
• Mercury Non-Toxicity: 1.00

Each of these elements was tested and found to be well within safe limits. A perfect score (1.00) across all four metals demonstrates that our product is clean, safe, and free from toxic contamination.

This is especially important in supplements, since heavy metals can quietly accumulate in the body over time, leading to serious health risks.

Why Did Unbox Health Rate iThrive Essentials Magnesium Bisglycinate an A+?

1. The Best Form: Magnesium Bisglycinate

When it comes to supplements, bioavailability is everything. You can take a pill loaded with magnesium, but if your body can’t absorb it, you won’t feel the benefits.

Many cheap supplements use forms like magnesium oxide or magnesium carbonate, which have very poor absorption rates. In fact, magnesium oxide has an absorption rate as low as 4%. That means your body gets almost nothing while your digestive system gets overloaded, often leading to discomfort, bloating, or diarrhea.

iThrive Essentials Magnesium Bisglycinate, however, is in a league of its own. It’s a chelated form, where magnesium is bound to two molecules of the amino acid glycine. This bond makes it:

• Highly absorbable: It bypasses common absorption issues in the gut.
• Gentle on digestion: Unlike oxide or citrate, it doesn’t cause diarrhea.
• Efficiently delivered to cells: Your body actually gets to use what you take.

2. Clean and Transparent Formula

The modern supplement industry is often crowded with products that contain unnecessary additives such as fillers, binders, preservatives, artificial colors, and even common allergens like gluten or soy. What many people don’t realize is that these extras can actually do more harm than good, particularly for those with sensitive digestion, autoimmune conditions, or allergies.

That’s why iThrive Essentials Magnesium Bisglycinate formula is kept 100% clean. Here’s what it doesn’t have:

• No fillers
• No preservatives
• No artificial colors
• No gluten
• No soy

It’s simply pure magnesium bisglycinate, nothing more and nothing less. This ensures that every capsule delivers only what your body truly needs, without any unnecessary ingredients that could compromise your health.

3. The Right Dosage

One of the biggest problems with magnesium supplements is dosage.

Some brands underdose, leaving you with barely 50 - 80 mg per serving, far below the therapeutic level. Others overload their capsules with 500 - 600 mg per serving, which sounds good on the label but often backfires by causing digestive distress and poor absorption.

iThrive Essentials Magnesium Bisglycinate delivers an optimal dosage per serving that is 440mg with 10% elemental magnesium in it. It’s:

• Strong enough to actually correct the deficiency.
• Safe enough to be taken daily without side effects.
• Balanced enough that you don’t need multiple capsules to hit your target.

4. Has a Lot of Benefits

• Stress & Anxiety Relief: Magnesium calms overactive nerve signals, while glycine acts as a natural relaxant. Together, they reduce the tension your body holds on to. This is why people often report feeling less “wired” and more centered after consistent use.
• Better Sleep Quality: Struggling to fall asleep or waking up restless? Magnesium supports melatonin which is your sleep hormone, while glycine helps your brain and body shift into a state of deeper, restorative rest. The result: you wake up feeling genuinely refreshed instead of groggy.
• Heart & Muscle Support: Magnesium is essential for keeping your heartbeat steady and your muscles functioning smoothly. Whether it’s regulating blood pressure or preventing those annoying leg cramps, this form of magnesium gives your cardiovascular and muscular systems the support they need.
• Energy at the Cellular Level: Every cell in your body runs on ATP, your energy currency, and magnesium is a critical part of its production. Without enough magnesium, you feel tired and sluggish. With the right levels, you’ll notice a steady, natural energy boost (no caffeine crash included).
• Easing PMS & Hormonal Fluctuations: For women, magnesium bisglycinate can be a game-changer. Research shows it reduces cramps, mood swings, irritability, and even bloating around menstrual cycles, making that time of the month far more manageable.

5. Tested for Purity and Safety

When it comes to supplements, safety matters just as much as effectiveness. Sadly, a lot of products out there don’t meet proper standards; heavy metals like lead, mercury, cadmium, and arsenic often slip into poorly sourced formulas.

That’s why iThrive Essentials Magnesium Bisglycinate is third-party lab tested for purity and safety. Each batch is carefully checked to ensure it’s free from harmful contaminants:

• Lead non-toxicity
• Arsenic non-toxicity
• Cadmium non-toxicity
• Mercury non-toxicity

This means every capsule you take is clean, safe, and trustworthy. You’re not just getting magnesium, you’re getting peace of mind that what you’re putting in your body has been rigorously tested and meets the highest quality standards.

Conclusion

Magnesium deficiency is widespread, but the solution isn’t just “taking any magnesium.” The form, dosage, and purity matter more than most people realize.

That’s why Magnesium Bisglycinate stands out. It’s bioavailable, gentle, effective, clean, and thoroughly tested. Whether you’re looking to improve your sleep, manage stress, boost your energy, or support your overall health, this is the form your body can actually use.

When you choose iThrive Essentials Magnesium Bisglycinate, you’re not just taking a supplement. You’re choosing clarity, science, and results you can truly feel.
