Benefits of a High Quality Magnesium Supplement
-
Improved Sleep Quality
-
Mood Balance Support
-
Muscle Recovery Support
-
Energy Level Management
-
Bone Health Support
Magnesium supplements seem to be growing in trends of people looking to optimise sleep, energy and recovery. Magnesiums role in these areas cannot be understated and its predicted that by 2030 magnesium supplements could be a £2bn industry.
The rise in sleep disorders and sleep quality concerns, particularly since the pandemic, has led more people to seek natural solutions. With growing awareness of magnesium's role in sleep regulation and relaxation, many are turning to it as an alternative to traditional sleep aids.
Women's Health Focus: Growing awareness of women's health issues, particularly around menopause and hormonal balance, has highlighted magnesium's benefits for managing these transitions naturally.
Mental Health Awareness: Greater recognition of stress, anxiety, and mental health challenges has driven interest in magnesium's calming properties. As people seek natural ways to support emotional wellbeing, magnesium's role in mood regulation has gained attention.
Changes in Modern Diet: Our current food system and processed diets often provide less magnesium than traditional diets. Soil depletion, food processing, and changing eating habits have reduced natural magnesium intake, creating a greater need for supplementation.
Aging Population: With more people living longer, there's increased focus on bone health and healthy aging. Magnesium's role in bone density and muscle function makes it particularly relevant for this demographic.
Magnesium FAQ
When Will I Notice Results?
Some benefits start within days. Sleep gets better in 1-2 weeks. Energy and mood improve in 2-4 weeks. Everyone is different, so your results may vary based on your body's needs.
How Can I Avoid Stomach Issues?
Many people get upset stomachs from magnesium. The best way to avoid this: look for forms like glycinate instead of oxide and delayed-release capsules that protect ingredients until they reach your intestines.
Taking magnesium with food and starting with a lower dose can also help reduce digestive discomfort.
Can I Take Magnesium With Other Vitamins?
Most vitamins work well with magnesium. Magnesium works best with vitamin D and zinc, which is why quality supplements often include these together.
Take iron or antibiotics at least 2 hours apart from magnesium. If you take medicine for your heart, blood pressure, or diabetes, ask your doctor first.
Which Types of Magnesium are Important?
Supplements with three different forms of magnesium provide multiple absorption pathways, reducing competition for absorption and creating a more sustained release profile. Each form has unique benefits - Glycinate for sleep and recovery, Citrate for quick absorption and energy, and Malate for sustained energy production.
This combination ensures comprehensive magnesium support throughout the day, maximizing both immediate and long-term benefits.
Why Do Some Magnesium Supplements Include Zinc and Vitamin D3?
The addition of Zinc is important in magnesium supplements because Zinc works synergistically with magnesium, enhancing magnesium absorption and utilization. It also provides enhanced muscle recovery and repair alongside the magnesium. Research shows that zinc and magnesium work together to improve exercise recovery, support deeper sleep and boost overall energy production.
Vitamin D3's inclusion is critical because it helps your body properly use magnesium and supports many of the same functions, like bone health and muscle performance.
What Dosages of Elemental Magnesium Are Suitable?
Clinical studies indicate around 200-400mg per day is usually enough to see real benefits. Many supplements contain too little active magnesium, sometimes as low as 50-100mg per serving.
These low doses often fail to reach therapeutic levels in your body. The form and quality of magnesium matters more than just the number on the label - look for supplements that clearly state the elemental magnesium content.
Why A Complete Magnesium Formula Matters
Taking just one type of magnesium is like having only one tool in your toolbox. For your body to get the full benefits, magnesium needs to work with other key nutrients and use the right delivery system.
Three Types of Magnesium Work Better Than One
• Glycinate helps you sleep better and recover faster
• Citrate gives quick energy when you need it most
• Malate provides steady energy throughout your day
Zinc Makes Magnesium Work Harder by helping your body absorb and use more magnesium. Research shows that zinc and magnesium together improve recovery after exercise, help you sleep deeper, and boost your energy levels.
Vitamin D3 works with magnesium like partners on a team. Your body needs both to keep bones strong and help muscles work properly. Many people don't get enough of either nutrient, making this combination especially valuable.
Special Delayed-Release Capsules protect the ingredients from stomach acid that can break them down too early. This means more magnesium reaches your intestines where it can be absorbed properly, causing less stomach upset and providing longer-lasting benefits.
What To Avoid:
Single-Form Magnesium
Supplements containing only one form of magnesium (especially oxide) typically have poor absorption rates and limited benefits. These basic formulations often cause digestive discomfort and fail to provide comprehensive support for sleep, energy, and recovery needs.
Low Elemental Magnesium
Many supplements advertise high magnesium content but contain minimal elemental magnesium (the active component). Quality supplements should provide at least 200-400mg of elemental magnesium per serving and clearly state this on the label.
Inadequate Dosage
Many supplements advertise high magnesium content but contain minimal elemental magnesium (the active component). Quality supplements should provide at least 200-400mg of elemental magnesium per serving and clearly state this on the label.

2. High Absorption Magnesium
7.8
Total Ranking
- Good bioavailability with magnesium glycinate
- Non-GMO and gluten-free formula
- Reasonably priced option
- Vegetarian-friendly capsules
- Single form of magnesium only
- Standard release capsules
- No nutritional table on website
- No additional supporting nutrients
The Bottom Line
Doctor's Best offers a decent entry-level magnesium supplement with their glycinate form providing better absorption than basic oxide supplements. However, it lacks the comprehensive approach of our top pick.
With no delayed-release technology or supporting nutrients, users may experience limited benefits primarily focused on general magnesium supplementation rather than targeted support for sleep, energy, and recovery needs.
3. Natural Calm
6.9
Total Ranking
- Powder form dissolves easily
- Pleasant flavored options available
- Well-established brand reputation
- Good for occasional stress relief
- Contains only magnesium citrate
- Some versions contain added sugars
- Can cause digestive discomfort in sensitive individuals
- Limited comprehensive benefits
The Bottom Line
Natural Vitality's powder format provides good absorption but falls short in comprehensive benefits. While effective for occasional stress relief, its single-form approach limits its effectiveness for sleep quality and recovery.
The addition of flavoring and sweeteners may be appealing for taste but unnecessary for optimal supplementation. Those seeking a complete magnesium solution will find this product too narrowly focused on relaxation benefits.
4. Magnesium Citrate
by NOW Foods
5.3
Total Ranking
- Budget-friendly option
- Consistent manufacturing standards
- Vegetarian-friendly capsules
- Good general-purpose supplement
- Basic single-form formulation
- No delayed-release technology
- Missing synergistic nutrients
- Provides limited targeted benefits
The Bottom Line
NOW Foods delivers a reliable but basic magnesium supplement at an affordable price point. While this citrate form offers better absorption than oxide, it lacks the sophisticated formulation needed for optimal benefits. Without delayed-release technology, users may experience digestive discomfort with higher doses. This supplement works for general magnesium needs but won't provide the targeted sleep, energy, and recovery support found in premium formulations.
5. Magnesium Oxide
5.3
Total Ranking
- Widely available in retail stores
- Affordable entry-level option
- Coated tablets for easier swallowing
- USP verified for purity
- Uses poorly absorbed magnesium oxide
- Basic formula without supporting nutrients
- Large tablets may be difficult to swallow
- Often requires higher doses for effectiveness
The Bottom Line
Nature's Bounty offers an accessible but inferior magnesium supplement. Its oxide form has among the lowest absorption rates of all magnesium types—as little as 4% bioavailability according to some studies. Users typically need higher doses to see minimal effects, which increases the risk of digestive discomfort. While the price point may be attractive, this basic formula lacks the quality ingredients and delivery system needed for meaningful health benefits.
