Buying Guide: How to Choose the Right NOW Magnesium Bisglycinate
Before you add a bottle to your cart, consider a few key factors that can make or break your experience. Not all magnesium glycinate supplements are the same, and understanding these differences ensures you get the most benefit for your money.
Magnesium Dosage and Elemental Magnesium Content
The label might say “magnesium glycinate,” but what matters is the elemental magnesium dose per serving. This is the actual amount of magnesium your body absorbs. Check the supplement facts panel to see how many milligrams of elemental magnesium you’re getting per tablet or capsule. For example, a product might have 2400 mg of magnesium glycinate complex, but only 240 mg of elemental magnesium. Aim for a dosage that aligns with your dietary needs and any guidance from your healthcare provider.
Also, consider how many pills you’ll need to take daily. Some options require two tablets twice a day, which might be inconvenient if you’re always on the go. If you prefer a lower pill burden, look for a higher concentration per serving. For more tips on choosing the right form, our NOW magnesium citrate review offers a comparison of different magnesium types.
Form: Tablets vs. Capsules
NOW offers both tablets and capsules. Capsules, especially those containing rice flour or other fillers, are often easier to digest and may be better for those with sensitive stomachs. Tablets are more compact and can be scored for splitting, but they may contain binders and fillers. If you have any allergies or dietary restrictions, always check the ingredient list for allergens like gluten, soy, or milk. NOW clearly labels these, making it easier to avoid unwanted additives.
Another consideration is whether the product includes enhancers like BioPerine (black pepper extract), which can improve absorption. While not essential, it can be a bonus if you’re looking to maximize benefits. If you’re curious about other NOW magnesium products, our NOW magnesium caps review provides more context.
Third-Party Verification and Brand Reputation
NOW Foods has been a trusted name in the supplement industry since 1968. They follow Good Manufacturing Practices (GMP) and have in-house laboratories that are ISO/IEC accredited for quality assurance. When choosing a supplement, look for brands that prioritize third-party certification, as this adds an extra layer of confidence. NOW’s commitment to quality is a significant reason why many health-conscious consumers stick with them.
While we can’t verify every claim, NOW’s transparency about their sourcing and manufacturing processes is reassuring. They also engage in sustainability efforts, like planting a tree for every 20 bottles sold of certain products. This attention to detail is something we appreciate and think you will too.

Frequently Asked Questions
What is the difference between magnesium glycinate and magnesium bisglycinate?
They are essentially the same thing. The terms are used interchangeably in the supplement industry. Both refer to magnesium bound to the amino acid glycine, which enhances absorption and is gentle on the stomach. So, whether you see “glycinate” or “bisglycinate,” you’re getting a highly bioavailable form of magnesium.
How much magnesium should I take daily?
The recommended daily allowance (RDA) for magnesium varies by age and gender, but for most adults, it ranges from 310 to 420 mg per day. However, this includes magnesium from all sources, including food. If you’re supplementing, it’s best to start with a lower dose and gradually increase, or follow the dosage on the product label. Always consult with a healthcare professional before starting any new supplement, especially if you have underlying health conditions.
Can I take NOW magnesium bisglycinate with other medications?
Magnesium can interact with certain medications, such as antibiotics and bisphosphonates, by reducing their absorption. To avoid this, take your magnesium supplement at least 2 hours before or after taking other medications. It’s always wise to discuss with your doctor or pharmacist to ensure there are no potential interactions. This is especially important if you’re on a regular medication regimen.
Are there any side effects of magnesium glycinate?
Magnesium glycinate is generally well-tolerated, but some people may experience digestive issues like diarrhea or stomach cramps, especially at high doses. Because glycinate is bound to an amino acid, it’s less likely to cause laxative effects compared to other forms like magnesium citrate. If you experience any discomfort, try reducing your dose or splitting it throughout the day. As always, listen to your body and adjust accordingly.
