Why we like Transparent Labs Magnesium Bisglycinate as best overall
Transparent Labs Magnesium Bisglycinate is our top choice because its made with a form of magnesium that your body absorbs and uses more easily. The main ingredient in this supplement, magnesium bisglycinate, is a chelated form of magnesium bonded to glycine, an amino acid. This type of magnesium absorbs better and is easier on the stomach compared to other types, such as magnesium citrate, reducing the likelihood of undesirable effects like abdominal cramps and diarrhea. ( 1 , 2 )
Adults need 310-420 milligrams of magnesium daily, depending on sex, age, and health. ( 1 ) Magnesium is an essential electrolyte and mineral thats involved in more than 300 enzymatic reactions. (1 ) It also helps regulate blood pressure and blood sugar, supports energy production, and aids in muscle contractions. ( 1 )
Though found in many foods like whole grains, leafy greens, nuts, seeds, meat, and poultry, more than 50% of Americans dont get enough magnesium in their diet. Low magnesium intake may increase the risk of high blood pressure, heart disease, and type 2 diabetes. ( 1 ) One serving of Transparent Labs Magnesium Bisglycinate has 300 milligrams of magnesium, meeting 70% of the daily value, and can potentially fill in nutrition gaps for people unable to get enough magnesium from food.
We do want to point out that the Food and Nutrition Board (FNB) established an upper tolerable (UL) limit of 350 milligrams for magnesium supplements to reduce the risk of undesirable effects. ( 1 )
Moreover, very large doses of magnesium5,000 milligrams and upmay be toxic and potentially fatal. However, this level of magnesium is usually by prescription and is in liquid form as the supplemental pill count would not be practical. In any case, if you take other multivitamin supplements, be sure to check the supplement facts label to make sure you dont get excessive supplemental magnesium. As a matter of good self-health practice, before adding them to your routine, you should also talk to your doctor about magnesium supplements, especially if the supplementation level is closer to the supplement UL noted above.
Many people turn to magnesium supplements to help with constipation, lower blood pressure, reduce stress, improve sleep, and reduce migraine headaches. ( 3 , 4 , 5 , 6 , 7 , 8 ) However, research is mixed for many of these purported benefits, and the supplement is only recommended as a treatment for constipation. ( 3 , 4 ) Though, the FDA recently stated that they wouldnt object to food and dietary supplement claims that magnesium lowers blood pressure. ( 9 )
Whether you need to supplement with magnesium is up to you and your doctor. Overall, Transparent Labs Magnesium Bisglycinate is a safe option that may help support optimal magnesium levels, benefitting overall health with little risk of unwanted side effects. Its also third-party tested, gluten-free, and has no artificial ingredients.
Though our testers said the capsules were large, they had no trouble swallowing them. Further, at $0.57 per serving, Transparent Labs is priced higher than the average market price for magnesium supplements. The magnesium supplement is a good value given its quality, effectiveness, and safety, but it may not fit all budgets.

Affordable

Cons

High-dose supplement not appropriate for daily use unless under medical supervision
Why we like Sunergetic Magnesium Complex as best for constipation
The magnesium citrate and magnesium oxide in Sunergetics supplement are both used to treat constipation. ( 3 , 4 ) Thats because these forms of magnesium remain intact as they travel through the digestive system, attracting water as they pass through. The extra water in the bowel loosens hard stool, alleviating constipation. ( 11 )
One Sunergetic magnesium capsule has 500 milligrams of magnesium. Though more than the upper tolerable limit set by the Food and Nutrition Board, its the right dose for the initial treatment of constipation. ( 1 , 4 ) That said, its best to consult your doctor to discuss the proper dose and length of treatment for your specific health needs. If constipation is a chronic problem, your doctor may provide long-term solutions to improve bowel health . Magnesium is only meant to serve as a short-term solution for constipation. ( 3 , 4 )
The Sunergetic supplement is made in a Good Manufacturing Practices (GMP) facility, but isnt third-party tested for quality and potency. The FDA doesnt independently test supplements like food and drugs, leaving it up to manufacturers to follow GMP guidelines to ensure their products are safe and effective. ( 12 ) Third-party testing is an independent study of the supplement that tests for ingredients, potency, and quality, and one of the measures we use when evaluating supplement safety. ( 12 )
Our product testers noted that the Sunergetic magnesium supplement capsule was large, the length of a quarter. While they had no problems swallowing the capsule, its something you may want to keep in mind if you have a hard time swallowing large pills. Another thing to consider before taking this supplement is that it may cause abdominal cramping and diarrhea. ( 4 )
At $0.14 per serving, Sunergetic Magnesium Complex is budget-friendly, priced about $0.20 less than the average market price. The supplement maker also offers a 100% money-back guarantee.
What customers are saying

Why we like Nutricost Magnesium Oxide as best for weight loss
Nutricost Magnesium Oxide provides one of the highest doses of magnesium on our list420 milligrams per serving. Not getting enough magnesium in your diet can make weight loss more challenging. According to a prospective follow-up study published in the European Journal of Nutrition , theres a strong link between low magnesium levels and obesity, separate from lifestyle choices like exercise and diet. ( 13 ) Providing 100% of your daily magnesium needs, the Nutricost supplement can fill in nutrient gaps.
The connection between low intake of magnesium and obesity isnt clear. However, the study suggests that the lack of magnesium may affect metabolism by disrupting energy production and interfering with the formation of lipids and proteins. ( 13 ) The authors recommend eating more magnesium-rich foods like whole grains, leafy greens, legumes, nuts, and seeds. ( 1 , 13 )
Our team agrees that eating a balanced diet filled with healthy foods is your best approach to healthy weight loss . But if youre struggling to get enough magnesium-rich foods on your reduced-calorie diet, Nutricost Magnesium Oxide can be helpful. However, given the high dose of magnesium, we recommend talking to your doctor before supplementing.
Magnesium oxide is the supplements source of magnesium, which is used to treat constipation. The supplement may cause unpleasant side effects like cramping and diarrhea. ( 3 )
In addition to its potential helpful effects, we also like the price of the Nutricost magnesium supplement. At $0.06 per serving, its the least expensive supplement on our list and well below the average market price. Its also third-party tested for quality and made in a GMP-compliant facility.
But, while Nutricost Magnesium Oxide may support your weight loss efforts, it wont work alone. Eating a balanced diet, adding more physical activity to your day, getting enough sleep, and finding healthy ways to manage stress (which magnesium can support) are needed, too. ( 14 )
Nutricost Magnesium Oxide is gluten-free but since the capsule is made of gelatin, which may come from animal bones, its not a vegan product. ( 15 )
What customers are saying
Most of the more than 3,400 reviews on Amazon for Nutricost Magnesium Oxide are positive. Consumers like the supplements effectiveness, quality, and results. However, some people find it too strong a laxative.
It has really helped me with my digestion.

Why we like Legion Athletics Sucrosomial Magnesium as best for migraines
Legion Athletics Sucrosomial Magnesium contains a form of magnesium with high bioavailability, so its absorbed and utilized easily by the body. For people who suffer from migraines, a fast-acting magnesium supplement may provide quick relief. ( 8)
Migraines are a common chronic headache that can cause debilitating pain. Researchers are still investigating the cause of migraines but have identified triggers, including low levels of magnesium. (2 ) Among magnesiums functions are maintaining blood vessel tone, regulating neural activity in the brain, and blocking pain receptors in the brain. ( 8 ) Its theorized that when magnesium intake is low, migraine pain may be triggered. (8 )
Though not a cure-all, The American and European Headache Society and the Neurological Academy suggest that 400-600 milligrams of magnesium a day may reduce the frequency and severity of migraines. ( 8 )
One Legion Athletics Sucrosomial Magnesium capsule has 150 milligrams of magnesium, meeting 36% of the daily value. Sucrosomial magnesium is magnesium oxide packaged in a special membrane that allows the magnesium to cross from the digestive tract and into the bloodstream intact, making more of the nutrients available for the cells and tissues in the body. ( 16 )
Though Legions magnesium supplement contains less than the recommended levels, you may absorb more than a traditional magnesium oxide supplement, making it more effective. ( 16 ) If you suffer from migraines and youre looking for a natural remedy to reduce pain, talk to your doctor about magnesium supplements and how they may help you.
We also like Legion Athletics Sucrosomial Magnesium because its third-party tested, NSF certified, and free of artificial ingredients and preservatives. However, we want to point out that the product comes with a Prop 65 warning, which requires businesses that sell consumable products in the state to list a warning if the product contains even trace amounts of lead, which could affect the nervous system. ( 17 ) When asked, Legion sought to clarify any doubts about the label: To give context, Prop 65 requires a warning on the label of any product that would result in a consumer ingesting more than 0.5 mcg of lead in a day. This is x lower than the highest level of lead known by California NOT to cause reproductive harm. Essentially, x this amount has been shown to have no observable effect on humans or animals.
Our team of testers found Legions magnesium supplement easy to swallow and said the capsule was smaller than other brands. However, one tester said that wasnt enough; they still wished the pill were smaller.
At $0.25 per serving, Legion Sucrosomial Magnesium is about $0.13 less than the average market price and a good value given the supplements bioavailability and quality. The magnesium powder is in a vegetarian capsule, but its unclear if it is vegan. One of our testers recommended opening the capsule, mixing the powder in water, and drinking it instead of consuming animal products.
What customers are saying
Amazon customers have a lot of good things to say about Legion Athletics Sucrosomial Magnesium supplement. They like the quality, ease of swallowing, and price.
HW is a verified Amazon buyer of Legions magnesium supplement and writes, I felt better going for higher absorption types of magnesium. I normally eat pretty healthy, but I use Cronometer to check my micronutrients and see most days Im not hitting the daily requirement for magnesium. This will supplement the rest of my diet well!
Some customers expressed concern about the lead content in the supplement.
Brian is a verified buyer who has concerns about lead in the supplement. This contains lead and says it on the package.

Why we like Transparent Labs ZMO as best for men
Transparent Labs ZMO contains nutrientszinc and magnesiumthat supports mens sexual and overall health. ( 31 ) The supplement contains 144 milligrams of magnesium, which is 35% of mens daily value, and 11 milligrams of zinc, which meets 100% of the daily value.
For one, both zinc and magnesium support mens physical and sexual health. ( 1 , 18) Low magnesium intake may play a role in age-related changes in testosterone levels and loss of muscle mass, so getting an adequate amount of the mineral may be necessary for general health and well-being. ( 19 )
Zinc is a trace mineral the body cant store, so you must get a regular supply from food or supplements. You need zinc to make DNA, support immune health, and heal wounds. ( 18 ) Zinc is also one of the main components of sperm. ( 20 ) Not getting enough zinc affects the quality and motility of sperm, increasing the risk of infertility in men. ( 20 )
Transparent Labs ZMO also contains oyster meat powder as a source of trace minerals. Though touted as an aphrodisiac, the sexual benefits of the shellfish may be related to its high zinc content, nearly 30 milligrams in a 3-ounce servingthree times the recommended amount. ( 18 , 19 )
While the sexual health benefits are clear, Transparent Labs ZMO is also designed to aid in recovery following an intense workout. Supplementing with magnesium may improve athletic performance, while zinc may support the muscle repair process. ( 27 , 28 ) Plus, as a magnesium supplement, Transport Labs ZMO helps you sleep better. ( 7 , 21 ) Sleep is an important part of post-workout recovery, giving your body the rest it needs to repair and build muscle. ( 29 )
We also like Transparent Labs because its third-party tested for quality and Informed Choice certified, which means it doesnt contain any banned substances. But its the most expensive supplement on our list, priced at $0.97 per serving.

Magnesium offers many health benefits for women. It supports bone health, heart health, and energy production. It may also ease symptoms and side effects caused by some of the unique health issues women face. Women with low magnesium levels are more likely to suffer from premenstrual syndrome (PMS)a set of symptoms like mood changes, bloating, and crampsthat occur before they start their period. ( 22 )
Women with polycystic ovary syndrome (PCOS) may also benefit from magnesium supplementation. PCOS is a hormonal condition that affects metabolism, insulin function, and fertility. ( 22 ) Insulin is a hormone that carries glucose from the blood into the cell; regulating blood sugars is one of the main functions of magnesium. ( 1 ) For women with PCOS, supplementing with magnesium may support insulin function by helping manage blood sugar levels. ( 22 )
Low magnesium levels also affect bone density, increasing the risk of osteoporosis, a serious bone disease that increases the risk of fractures. ( 22 ) Women are more susceptible to osteoporosis after menopause because they have thinner bones than men and no longer have the estrogen that supports bone building. ( 22 )
Our product testers liked the effects of Future Kind+ magnesium supplement, reporting that it improved their sleep quality, muscle relaxation, and headaches. They also liked that the magnesium was in a form thats gentler on the stomachmagnesium bisglycinate chelate, causing fewer side effects. ( 2 )

Why we like Nutricost Magnesium Taurate as best for blood pressure
Nutricost Magnesium Taurate is a form of magnesium thats bonded to taurine, an amino acid. Both magnesium and taurine benefit heart health and blood pressure and make a good choice for those looking for a supplement to improve blood pressure. ( 1 , 5 , 9 , 23 )
High blood pressure, also called hypertension, is when the force of blood against the artery walls is too high. ( 25 ) In general, hypertension is a blood pressure reading of 130/80 millimeters of mercury or higher. Over time, the excess pressure makes the arteries less flexible, so the heart has to work harder to pump blood throughout the body. Having high blood pressure increases the risk of heart attack, stroke, and kidney disease. ( 25 )
Due to supportive evidence, the FDA allows food and supplement makers to make a qualified claim that diets high in magnesium may reduce the risk of high blood pressure . ( 9 ) The mineral improves blood pressure by relaxing blood vessels and improving fluid and electrolyte balance. ( 1 , 23 ) Magnesium and taurine may lower blood pressure, however, no sufficient research has been done on humans, only in animals. ( 24 )
Nutricost Magnesium Taurate contains 120 milligrams of magnesium, which meets 30% of the daily value, however, it does not meet the effective range of 500-1,000 milligrams for lowering blood pressure. ( 23 ) Though it falls a bit short on dose, you may find it more tolerable since its in a form thats easier to absorb.
At $0.20 per serving, Nutricost Magnesium Taurate is a good value, priced below the average market cost of magnesium supplements. That said, you need to take three capsules to get the recommended dose. If you have a hard time swallowing pills, you may prefer a supplement that doesnt require so many pills.

Who should take a magnesium supplement?
Magnesium supplements can be helpful for people who might not be getting enough magnesium in their diet, which could show up as muscle cramps, fatigue, or even an irregular heartbeat. ( 1 ) If you have conditions like high blood pressure, migraines, or trouble sleeping, a magnesium supplement might also be a good idea. Athletes, those with certain digestive issues, or anyone not eating enough magnesium-rich foods might consider taking a supplement to stay on track with their health. Any new supplement should be discussed with your doctor before taking it.
Who should not take a magnesium supplement?
If you have kidney problems or your kidneys arent working as well as they should, its best to avoid magnesium supplements unless your doctor says its okay since your body might struggle to get rid of the extra magnesium. ( 33 ) This is because your kidneys might not effectively filter out excess magnesium from your blood.
In addition, if you take medications such as antibiotics or diuretics, you should speak with your doctor first because some medications may interact.
Pregnant or breastfeeding women should always consult with their healthcare provider before adding any new supplements.
How to choose a magnesium supplement
When looking for a magnesium supplement to add to your routine, there are a few things to consider:
Reason for supplementation
People turn to magnesium supplements to achieve various health goals, from better sleep to stronger bones to lower blood pressure. You need to consider why you want to supplement with magnesium when selecting a product. Magnesium supplements may contain other active ingredients that may support or hinder your goals.
Magnesium type
Magnesium comes in many types. You may prefer certain types because your body tolerates them better or because they support specific goals. Types of magnesium include:
- Magnesium citrate: Recommended by healthcare professionals to alleviate constipation. ( 3 )
- Magnesium oxide: Often recommended by healthcare professionals to relieve heartburn, indigestion, or constipation. ( 4 )
- Magnesium glycinate: A type of magnesium bonded with the amino acid glycine for easier absorption. A supplement you can use to improve magnesium levels, ease anxiety, and sleep better. ( 2 , 7 , 30 )
- Magnesium sulfate: Also known as Epsom salt, this form of magnesium treats constipation and magnesium deficiency. ( 26 )
- Magnesium taurate: Magnesium bonded with the amino acid taurine for better absorption. Used to boost magnesium intake and may help reduce the risk of high blood pressure. ( 9 , 24 )

You must also consider the dose when looking for the right magnesium supplement. Adults need 310-420 milligrams of magnesium a day depending on age, sex, and health status. ( 1 ) Taking high doses of magnesium in supplement form, more than milligrams a day, is dangerous and potentially fatal, causing an irregular heartbeat or cardiac arrest (your heart stops beating). ( 1 )
Because of the possibility of side effects with supplements, like diarrhea and abdominal pain, the Food and Nutrition Board has set an upper tolerable intake level of 350 milligrams for magnesium supplements. ( 1 )
Magnesium form
Magnesium supplements also come in many forms, such as capsules, chewable tablets, and gummies. Some magnesium capsules are large and difficult to swallow. Your preferred supplement form can help narrow down your choices.
Third-party testing
Supplements arent regulated like medications. The FDA requests that supplement companies use Good Manufacturing Practices (GMP) when producing and selling supplements. ( 12 ) This means the FDA leaves it up to the supplement maker to determine if their supplement is safe and effective.
Third-party testing is an independent lab evaluation of a supplement that checks ingredients, quality, and potency. Testing isnt required, but its one of the factors we look for when evaluating supplements for safety.
Expert advice
Talk to your doctor or a registered dietitian about magnesium supplements before adding them to your routine. They can guide you on the best type and dose based on your health needs and goals.
Potential side effects of magnesium supplements
When taken as recommended, most healthy people should not experience any side effects from magnesium supplements. However, taking higher than recommended doses can have adverse effects like abdominal pain, bloating, or diarrhea. Further, taking megadoses of magnesium5,000 milligrams or moreper day is potentially life-threatening. ( 32 )
Magnesium supplements may also interact with medications. For example, magnesium can affect the absorption and dosage of medications used to treat osteoporosis (bisphosphonates), as well as some antibiotics.
FAQs
When is the best time to take magnesium supplements?
The best time to take magnesium supplements depends on your personal health goal. If youre using magnesium to help you sleep better, then you want to take the supplement before bed. If you need relief from constipation, you should take the supplement earlier in the day with food to reduce risk of stomach upset. ( 4 ) Split doses can also be used to provide benefits throughout the day for different needs.
Which is the best form of magnesium to take?
The most effective form of magnesium depends on why you want to take the supplement. If you want to lower blood pressure or sleep better, you may prefer a supplement thats easier on the stomach, like magnesium glycinate. ( 2 ) On the other hand, magnesium citrate or magnesium oxide may be more effective for alleviating constipation. ( 3 , 4 )
How much magnesium is safe to take?
Talk to your doctor or a registered dietitian for guidance on how much magnesium is safe for you to take. There are no limits on the amount of magnesium you can get from food; adults need 310-420 milligrams daily. ( 1 ) If youre getting enough magnesium from your diet, you may not get any benefits from a supplement. ( 1 ) If you do supplement (whether you get enough from food or not), the Food and Nutrition Board (FNB) recommends getting no more than 350 milligrams of magnesium from a supplement to reduce the risk of stomach cramps and diarrhea. ( 1 )
Is it OK to take magnesium glycinate every day?
Whether you take magnesium supplements daily depends on your health goal. The body stores magnesium, so you may not need to take it daily. ( 1 ) Though, the body stores about 25 grams, so supplementation isnt a bad idea, since doses recommended range from 300 to 400 milligrams. Talk to your doctor for specific guidance on how often you need to take magnesium supplements.
What type of magnesium helps with sleep?
Magnesium is widely recognized for its sleep-enhancing benefits, primarily due to its ability to promote relaxation and calm the nervous system. ( 7 ) Among the different forms of magnesium, magnesium glycinate is considered one of the best for sleep. Its highly absorbable and known for its calming effects, making it ideal for promoting relaxation and reducing anxiety before bed. ( 34 ) Products like Transparent Labs ZMO use magnesium glycinate specifically for its ability to support restful sleep without causing digestive discomfort.
What type of magnesium lowers blood pressure?
Magnesium taurate combines magnesium with taurine, an amino acid that supports heart health and blood pressure regulation. ( 1 , 35 ) Together, they work to relax blood vessels and improve blood flow, making it a popular choice for those looking to manage hypertension.
What is the difference between magnesium glycinate vs citrate?
Magnesium glycinate is magnesium bound to glycine, an amino acid known for its calming effects. Its highly absorbable and gentle on the stomach, making it less likely to cause digestive issues like diarrhea. Magnesium glycinate is often recommended for those looking to improve sleep, reduce anxiety, or support relaxation, as it has a calming effect on the nervous system. ( 34 )
Magnesium citrate is magnesium combined with citric acid. Magnesium citrate is often used to relieve constipation due to its mild laxative effect, as it draws water into the intestines. ( 35 ) Its a good option for those who need digestive support or want to address magnesium deficiency quickly.
