What is Magnesium?
Magnesium is an essential mineral found in every cell, crucial for over 300 enzyme-driven processes.
Roughly 50–60% of the body’s magnesium is stored in the bones, supporting not only bone strength but also various metabolic functions.
Studies suggest it may help maintain cardiovascular health, muscle recovery, sleep quality, and more.
Magnesium Powders Can Help With:
What To Look For In A Magnesium Powder
Choose a magnesium powder that uses highly bioavailable forms—such as magnesium citrate, glycinate, or malate—which are more efficiently absorbed by the body. Less absorbable forms may lead to gastrointestinal discomfort, including diarrhea, so opt for formulations that prioritize bioavailability.
Select a product that is proudly made in the USA, where strict manufacturing quality standards are enforced. Additionally, look for supplements that are independently third-party tested to ensure they meet high standards of quality and safety.
A reputable magnesium supplement should come with a 60-day money-back guarantee. This allows you to try the product risk-free, confident in the manufacturer’s commitment to quality.
Ensure that the brand offers a straightforward return policy. If you’re not satisfied with the product, the process should be simple and hassle-free—avoid brands that make returns or refunds overly complicated.
What To Avoid
Steer clear of magnesium supplements that include unnecessary additives, fillers, or artificial ingredients. These extra components can dilute the product's potency and may cause unwanted side effects in sensitive individuals.
Be cautious of any supplement that claims to treat or cure specific conditions or promises unrealistic results. Such claims can be misleading. Always consult with your healthcare provider before starting any new supplement regimen.
Choosing the cheapest option can sometimes mean compromising on quality. Ensure that the supplement clearly identifies its ingredients and their dosages. A low price without transparency might lead to an ineffective or even potentially harmful product.

2. Thorne Magnesium Bisglycinate
9.0/10
TOTAL RANKING
A
OVERALL GRADE
PROS
- Bisglycinate with great bioavailability.
- Popular brand.
- NSF certified for sports.
CONS
- Costly at $0.75 per serving.
- Only 200mg per scoop.
Thorne is a leading company in the supplement industry, known for their quality ingredients, exceptional customer service, and outstanding products. Their berberine supplement is no exception, becoming one of the top-selling berberine products on the market with over 4,000 raving reviews on Amazon.
The berberine supplement from Thorne contains 450 mg of Berberine HCL and 550 mg of Berberine Phytosome complex, making it a potent and diversified formula.
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.
Conclusion
Thorne is a leading name in the supplement industry, renowned for its commitment to quality and science-backed formulations.
Their Magnesium Powder is no exception, featuring magnesium bisglycinate—a highly bioavailable form that ensures optimal absorption for enhanced muscle relaxation, energy production, and overall wellness.
Popular among athletes and health enthusiasts alike, this product also carries NSF certification for sports, underscoring its quality and purity.
However, there are a couple of considerations. Each scoop delivers 200 mg of magnesium, which may be on the lower side for those with higher daily needs.
Simply taking two servings a day is an option but the cost is a bit steep at approximately $0.75 per serving, making it one of the pricier options on the market.
Overall, if you value top-tier ingredients, exceptional bioavailability, and a trusted brand with a strong reputation, Thorne Magnesium Powder is an excellent choice—even if its premium price and modest per-serving dosage require careful consideration.
3. Pure Encapsulations Magnesium (Powder)
8.7/10
TOTAL RANKING
B+
OVERALL GRADE
PROS
- Sold on popular marketplaces.
- Well-absorbed magnesium citrate.
- Money-back guarantee.
CONS
- Only 250 mg per serving.
- Not as affordable as other options.
Berberine Plus is another popular option on the market, making it convenient to order.
One of our concerns was that many people have reported headaches and stomach issues when using this supplement, although this is also the case for other berberine brands, as it's a side effect of berberine itself.
The reason it earned the third spot on our list is partly because ordering directly from their website was a bit tricky, with limited information on the guarantee and return process.
Their formula contains 1200 mg of Berberine HCl and 10 mg of royal jelly, making it a unique and potent formula.
Overall, it's a great product offered at a reasonable price which is why it has become of the best selling supplements on Amazon.
Reason for the third placement is the lack of 24/7 customer service and not as strong money back guarantee, but besides from that, it's a good choice.
Conclusion
Pure Encapsulations is a well-regarded brand in the supplement industry, known for its commitment to high-quality, science-based formulations.
Their Magnesium Powder features magnesium citrate—a form recognized for its excellent absorption—to support muscle relaxation, nerve function, and overall wellness.
Sold on popular marketplaces, this product is easily accessible and has garnered a positive reputation for its effectiveness.
However, there are a few points to consider. Each serving delivers 250 mg of magnesium, which might be on the lower side for those needing a higher dose.
Additionally, while the price is reasonable relative to some premium brands and there is a money-back guarantee, it may not be the most affordable option available on the market.
Overall, if you prioritize well-absorbed ingredients and reliable quality, Pure Encapsulations Magnesium Powder is a solid choice. Just keep in mind the modest dosage and cost when comparing it to other available options.
4. Nutricost Magnesium Glycinate Powder
8.2/10
TOTAL RANKING
B
OVERALL GRADE
PROS
- Third-party tested.
- Well-absorbed magnesium bysglycinate.
- Affordable, with money-back guarantee.
CONS
- Only 210mg per serving.
- Unflavored, which may be disliked by some.
Toniiq's High Strength Berberine is another excellent supplement sold in the U.S with 97% purity, and sources its ingredients from the Himalayas.
They clearly have a high priority in clean, high quality ingredients with a 500 mg pure berberine formula.
In addition to this, they have 90 capsules in each box. Although the price tag is slightly higher than others on the market, the price per capsule comes out to be cheaper than many other top brands.
If you have purity as your main focus, want to have smaller dosages in each capsule and a medium price tag, then this would be a good choice for you.
Conclusion
Nutricost Magnesium Glycinate Powder is an excellent option if you're seeking a budget-friendly, high-quality magnesium supplement.
Third-party tested to ensure purity and backed by a money-back guarantee, this product offers both reliability and value. It features magnesium glycinate—a highly bioavailable form known for its gentle effect on the digestive system—making it effective for supporting muscle relaxation, promoting restful sleep, and maintaining overall wellness.
That said, there are a couple of points to consider. Each serving provides 210 mg of magnesium, which might be on the lower side for those with higher daily needs.
Additionally, the unflavored formula may not appeal to everyone, especially if you prefer a supplement with a more palatable taste. In fact, some customers report a fishy or metal taste that may be difficult to tolerate.
Overall, if you value affordability, proven absorption, and the reassurance of third-party testing, Nutricost Magnesium Glycinate Powder is a strong choice.
5. Micro Ingredients Pure Magnesium Citrate Powder
7.9/10
TOTAL RANKING
C+
OVERALL GRADE
PROS
- 500mg per serving.
- Very affordable.
- Well-absorbed magnesium citrate.
CONS
- No transparent testing information.
- Unflavored.
- Limited guarantees.
Landing the final position on our list, Luma Nutrition's berberine is by no means the least in terms of quality. Among the over 20 brands we evaluated, our standards were rigorous.
Despite its ranking, this product stands out for its merits. It's distinguished by its clean, straightforward formulation, primarily featuring berberine HCl, which offers enhanced bioavailability compared to standard berberine. This means a significant portion of the dose is effectively used by the body.
The high absorption rate of its 1200 mg capsules may outperform even higher-dose products in terms of efficacy.
However, the product does have some downsides: a simplistic design, the absence of round-the-clock customer support, and larger capsule size.
Conclusion
Micro Ingredients offers a compelling option with their Pure Magnesium Citrate Powder, delivering a robust 500 mg per serving—a standout among magnesium powders.
This well-absorbed magnesium citrate formulation is designed to support muscle relaxation, nerve function, and overall wellness, all at a very affordable price point.
However, there are a few considerations. The product lacks transparent testing information, which means it’s unclear how rigorously its purity and quality are verified.
Additionally, its unflavored formula might not suit everyone’s taste preferences, and the limited guarantees may not provide the reassurance some consumers desire.
Overall, if you’re looking for a potent and cost-effective magnesium supplement and are comfortable with fewer assurances regarding third-party testing, Micro Ingredients Pure Magnesium Citrate Powder could be an excellent choice.
