What is Berberine?
Magnesium is a must-have mineral in every cell. It's the fourth most common mineral in the body and is vital for over 300 enzyme reactions, keeping us healthy. [1]
Most of this crucial mineral resides in our bones, making up about 50-60% of it. That's why it's essential to maintain magnesium levels for strong bones, and for many other health reasons too. [2]
Magnesium Glycinate Can Help With:
- Sleep Quality
- Reducing Muscle Cramps and Spasms
- Heart Health
- Immune Function
- Lowered Risk of Hypertension
Stress, Sleep, and Mood
Magnesium isn't just crucial for physical health; it's vital for mental health as well. Your mood, stress levels, and the quality of your sleep are all significantly influenced by magnesium levels.
For instance, magnesium plays a key role in controlling our stress-response mechanisms, which explains why individuals with magnesium deficiency frequently feel more stressed. Additionally, it boosts the production of GABA, a neurotransmitter that promotes relaxation and deep sleep.
Research on magnesium supplements has demonstrated a positive relationship with enhanced sleep quality, decreased stress, and increased overall calmness. [3] [4]
Not all magnesium supplements are created equal. Various brands utilize different components, resulting in varying effectiveness among formulas.
Selecting the best magnesium formula comes down to knowing what to look for and what to steer clear of, ensuring your investment is worthwhile. We've analyzed leading magnesium supplements, empowering you to make informed choices and avoid wasting your resources.
What Are The Different Types of Magnesium?
Magnesium Glycinate
Glycine, an amino acid paired with magnesium, enhances absorption. Alongside magnesium, it stimulates GABA release, rendering magnesium glycinate optimal for promoting sleep and relaxation. Due to its remarkable absorption rate, magnesium glycinate is widely recognized as the premier magnesium form available. [5]
Magnesium Citrate
Magnesium citrate ranks as the most bioavailable magnesium type, navigating the gut's volatile regions effortlessly. Additionally, citrate aids in digestive regulation. Forms bound with citric or malic acid are prevalent and cost-effective options in supplements. [6]
Magnesium Malate
Similar to citrate, magnesium malate has citric or malic acid, and it is a cheaper and more common form of magnesium. Besides being highly bioavailable, magnesium malate is also known for its antacid properties. [6]
Magnesium Oxide
When bound with oxygen, magnesium is primarily utilized for digestive concerns. Glycinate boasts four times the absorption rate compared to magnesium oxide.
What To Avoid
Additives and Fillers
Avoid berberine supplements that contain unnecessary additives, fillers, or artificial ingredients. These can dilute the potency of the supplement and may cause adverse reactions in some individuals.
False or Misleading Claims
Beware of any supplements that claim their product treats or cures any specific disease or ailment, or promises miraculous, unrealistic, or misleading results. Always speak to your doctor before starting a new supplement routine.
The Lowest Priced Option
Selecting the cheapest rather than the best quality can potentially do you more harm than good. If brands don’t identify certain ingredients or nutrients and their amounts in each dose, you could end up with an ineffective or potentially harmful supplement.
Potential Signs of Low Magnesium Include:
- Loss of appetite
- Nausea
- Vomiting
- Fatigue
- Weakness

Click To Shop Now »The Magnesium Bisglycinate Powder by Thorne Research secures one of the top positions on our list for its premium quality and simple composition. It's an excellent choice for those who prefer not to take capsules, offering the flexibility to mix the supplement into foods or drinks.
This supplement is made by attaching magnesium to glycine, an amino acid. Studies in animals and in vitro have indicated that glycine might exert a soothing influence on the brain, contributing to its potential benefits for enhancing sleep quality.
Given their stellar reputation and the clean, potent formula, we are confident in awarding it one of the top spots in our review.
However, Thorne's berberine comes with a high price tag. Thorne also offers a 60-day guarantee, but it's important to note that you will need to cover the return shipping costs if you order directly from their website and not from a marketplace.
Overall, it's an excellent product, and if price is not a primary concern, it's a fantastic choice.

- Includes 50mg of spinach serving.
- Tested for over 125 chemical substances.
Cons
- Small number of reviews.
- Lack of potency.
- Limited guarantees.
Conclusion
MegaFood Magnesium Capsules, while containing magnesium glycerate, rank last among magnesium glycerate supplements due to several factors. Their potency is notably lower compared to other brands, offering a dosage that may not meet the needs of individuals seeking higher doses for specific health concerns or deficiencies.
Despite the presence of magnesium glycerate, known for its relatively high absorption rate, users have reported inconsistent results with MegaFood Magnesium Capsules, with some experiencing minimal improvement in magnesium levels.
Pricing may also be a concern, as the product's effectiveness may not justify its cost, especially when compared to other brands offering higher potency and better absorption at similar or lower prices. Feedback from consumers has been mixed, with some reporting satisfactory outcomes while others express disappointment in the product's efficacy, citing a lack of noticeable effects on energy levels, sleep quality, and overall well-being.
Overall, while MegaFood Magnesium Capsules provide a convenient option for obtaining magnesium glycerate, they may not offer the potency, absorption, and effectiveness desired by individuals seeking optimal magnesium supplementation.
