Thorne Magnesium Bisglycinate

Q: How much magnesium is in one serving?

One scoop provides 200 mg magnesium , according to the current public iHerb listing.

Q: Is this product third-party certified?

Yes. Public NSF search results list it as NSF Certified for Sport . If you want to understand how that differs from other verification language, see what third-party tested means and USP vs NSF .

This is a premium magnesium powder built around one clear idea: a 200 mg magnesium bisglycinate serving in a scoopable, sweetened format with NSF Certified for Sport. That makes it more distinctive on form, powder convenience, and sport certification than on being uniquely proven for everyone. If those features matter to you, it can make sense. If not, the price and powder format are real reasons to keep comparing options in our product guide and broader magnesium guide.

Best for: people who want a powdered magnesium bisglycinate, athletes who value NSF Certified for Sport, and shoppers who prefer mixing a drink over swallowing pills
Skip if: you want the cheapest magnesium option, dislike sweetened powders, or prefer a simple capsule or tablet
Form: magnesium as magnesium bisglycinate powder
Active dose: 200 mg magnesium per 1 scoop serving
Servings: 60 servings per container
Quality markers: NSF Certified for Sport, gluten free
Price band: premium, with the current public iHerb listing at $52.00, or about $0.87 per serving

Label facts snapshot

This is the stuff shoppers usually want to know first: how much magnesium you really get, what else is in the tub, and whether the daily routine feels easy or annoying.

Serving size

What the label actually asks you to take

1 scoop

The public listing uses one scoop in water, not a capsule or tablet. That makes this easier at home and less convenient on the go.

Real magnesium

How much magnesium you really get

200 mg elemental magnesium

The useful number is the elemental magnesium, not the scoop weight. That 200 mg figure is the one to compare across brands.

Other ingredients

What changes the feel of the product

Citric acid + monk fruit

This is a sweetened powder. That can make it easier to drink, but it also means it is not a plain neutral formula.

Routine burden

What daily use feels like

Low pill burden, higher prep burden

You skip the tablets, but you do have to mix a scoop. People who travel a lot or hate mixing may care more about that than the form itself.

Why this product exists on the site

Readers usually land on this page before buying or skipping. The goal here is not to repeat brand marketing. It is to explain what stands out, where the tradeoffs are, and what to compare next.

Thorne Magnesium Bisglycinate earns a place in our product coverage because it sits in a specific niche: a premium powder using magnesium bisglycinate, with NSF Certified for Sport positioning. That combination will matter to some shoppers and be irrelevant to others. For a form-first decision rather than a brand-first one, the better starting point may be our parent guide to magnesium supplements.

Formula breakdown

According to the current public iHerb listing, one scoop is 3.11 g and provides 200 mg magnesium as magnesium bisglycinate. The container provides 60 servings. Suggested use on that listing is to mix 1 scoop with at least 8 ounces of water daily, or as recommended by a health-care practitioner.

The listed other ingredients are citric acid and monk fruit concentrate. That matters because this is not a plain unflavored powder. For some people, that improves usability. For others, it creates a taste or sweetener issue that a capsule would avoid.

Most of the evidence people care about here is evidence on magnesium as a nutrient and sometimes on magnesium forms, not on this exact branded product. If you are deciding between forms rather than between logos, see our comparison of magnesium glycinate vs citrate.

Studied dose vs label reality

People search for things like “best magnesium glycinate dose for sleep” or “is 200 mg enough.” The honest answer is that there is no one magic magnesium number that works for every goal.

Label dose

What one serving gives you

200 mg

This lands in a very normal supplement range for people who just want to add magnesium without going straight to the high end.

What people compare

The real shopping question

100 to 350 mg is the usual comparison lane

Most shoppers are not comparing one “studied sleep dose.” They are comparing total supplemental magnesium, side effects, and whether the form feels easier on the stomach.

Dose verdict

Does the label make sense?

Roughly aligned Makes sense for everyday magnesium math

It is not underdosed for a basic magnesium product. The bigger issue is whether you want this powder format and price tier.

Biggest catch

What the label does not solve

No product-specific proof

The evidence is about magnesium intake and sometimes magnesium forms. It is not proof that this exact Thorne tub works better than every cheaper glycinate option.

What looks strong

The form is clear and specific. This is not a vague “magnesium blend.” The product states magnesium as magnesium bisglycinate, which is exactly the kind of detail shoppers should look for when using our guide on how to compare magnesium products.

The dose is straightforward. A single scoop provides 200 mg magnesium, which is easy to understand and compare with your total intake from food and supplements.

The certification is a real differentiator. Public NSF search results list this product as NSF Certified for Sport. That will matter most to competitive athletes or anyone who places extra value on that type of certification.

The formula is fairly simple. Outside the active magnesium form, the listing names only citric acid and monk fruit concentrate. For a flavored powder, that is relatively streamlined.

The powder format can be a feature, not just a format choice. Some readers simply do better with a drink mix than with tablets or capsules, especially if they are already using evening routines for sleep support habits or want flexibility around the best time to take magnesium.

What looks weak and what the tradeoffs are

The price is firmly premium. At the current public iHerb price of $52.00 for 60 servings, this is not the budget way to buy magnesium. You are paying for brand positioning, powder format, and NSF Certified for Sport status, not just the mineral itself.

The powder format adds friction. A scoop and water can feel easy at home, but less easy during travel or busy mornings. If your main goal is simplicity, a basic capsule or tablet may win.

Taste is part of the product whether you care about it or not. Citric acid and monk fruit make this more than a neutral powder. Some people will like that. Others will immediately prefer an unsweetened or pill-based option.

“Gentler form” does not mean “no side effects.” Magnesium can still cause stomach upset or loose stools in some users, and dose still matters. If that is a concern, read our guide on whether magnesium can cause diarrhea.

It is not uniquely proven. The science that supports magnesium supplementation generally comes from studies on magnesium intake or magnesium forms, not on this exact product. That is important context when deciding how much premium you want to pay.

Who this product may fit

This product may fit you if your checklist looks like this:

you specifically want magnesium bisglycinate rather than a mixed or unspecified form
you prefer a powdered drink to capsules or tablets
you want a moderate, easy-to-read 200 mg magnesium serving
you are an athlete or drug-tested competitor who values NSF Certified for Sport
you are comfortable paying more for that combination of features

If you are still deciding whether glycinate is even the right form for you, it may be smarter to step back and compare forms first, including glycinate vs citrate and citrate vs oxide.

Who should skip it

You may want to skip this product if any of these apply:

you are shopping on price first and do not need sports certification
you dislike sweetened or flavored powders
you want the lowest-effort option, and a capsule or tablet would be more realistic for daily use
you prefer unflavored products with no monk fruit
you are taking medicines with known magnesium interaction potential and have not reviewed magnesium interactions

If you have kidney concerns, complicated medication use, or you are not sure whether magnesium is appropriate for you at all, that is a good point to review when to talk to a clinician before choosing a product.

Red flags before you hit buy

These are the friction points most likely to make you regret the purchase later, even if the label looked good at first.

Stop here if you hate flavored powders. Monk fruit and citric acid are small details on paper but a big deal if taste already annoys you.
Do not buy this just because it says glycinate. Plenty of shoppers would do just as well with a simpler glycinate tablet at a much lower price.
NSF Certified for Sport matters most for a narrow group. If you are not a tested athlete or very certification-focused buyer, that premium may not be worth it.

Price analysis

The current public iHerb listing shows $52.00 for 60 servings, which works out to about $0.87 per serving. That places Thorne Magnesium Bisglycinate in the premium tier for routine magnesium shopping.

That does not automatically make it overpriced. It means you should be clear on what you are paying for:

powder format instead of pill format
magnesium bisglycinate positioning
NSF Certified for Sport status
brand preference

If you do not strongly value those points, a simpler magnesium product may offer better value. The best way to compare is not by label claims alone, but by the actual magnesium form, active amount, servings, and verification details. We break that down in how to compare magnesium products and magnesium testing explained.

Price per meaningful dose

Sticker price alone does not tell the whole story. The better question is whether the price still looks reasonable after you convert it into actual magnesium delivered.

Per serving

Cost each time you use it

About $0.87

That is clearly premium territory for magnesium. The price is doing a lot of the talking here.

Per 100 mg

Cost per useful magnesium amount

About $0.44

This makes it easier to compare with labels that use smaller or larger magnesium servings.

What you are paying for

Where the premium goes

Powder + brand + NSF

This is not just a magnesium purchase. You are paying for powder convenience, a premium label, and the sports certification story.

Quality verification

The strongest public quality signal here is NSF Certified for Sport. The public NSF search tool lists Thorne Magnesium Bisglycinate as a certified powder product with 1 scoop serving size. That is a more meaningful verification point than vague “tested” language on its own.

It is also worth being precise about what certification does and does not mean. NSF Certified for Sport is not the same thing as saying a product is best for everyone, and it is not interchangeable with other seals. If you want the distinction, see USP vs NSF and what third-party tested means.

The iHerb listing also includes retailer language about sourcing products directly from brands or authorized distributors. That may be useful for retailer trust, but it should not be treated as proof of overall superiority beyond the specific listing and certification details.

What this product is really implying

This is where brand messaging and evidence can drift apart. The goal is not to call the product fake. It is to separate what the label implies from what the evidence really supports.

Marketing angle

What the page is nudging you to think

Premium glycinate powder, great-tasting, sport certified, and gentler than other forms. That can sound like the obvious “best magnesium” move.

Evidence reality

What the research actually supports

Magnesium matters. Form can matter. But the evidence people care about is not a head-to-head proof that this exact powder beats every simpler glycinate tablet.

Shopping takeaway

What to do with that gap

Buy this if the powder format and NSF signal solve a real problem for you. If not, compare cheaper glycinate products first and keep the decision boring.

Use-case fit and evidence context

Use Case	Evidence	Typical Time Window
General magnesium support	Moderate	Usually days to weeks in routine use.
Bedtime routine support	Mixed	Often framed as days to a few weeks.
Muscle comfort or cramp questions	Mixed	Depends on cause, intake, and context.
Constipation relief	Lower-fit form	Glycinate is not the usual first pick here.

The best evidence context for this product comes from the National Institutes of Health Office of Dietary Supplements. Magnesium is an essential mineral involved in many body processes, and supplements are commonly used to help fill intake gaps. But the evidence people often want for goals like sleep, muscle comfort, or general calm is usually about magnesium intake or magnesium forms overall, not this exact Thorne powder.

That means the product decision should be practical: do you want a bisglycinate powder, in this dose, at this price, with this certification? If yes, the product makes sense. If you mainly want “some magnesium,” then the broader magnesium overview may help more than a brand page.

If your main question is routine use, timing, or goal fit, start with the basics on best time to take magnesium and our evidence-aware page on sleep. If your main concern is safety, read magnesium interactions and when to talk to a clinician.

What real users often report

Anecdotal only. This block summarizes recurring themes from public discussion threads. It is useful for spotting tradeoffs, not for proving outcomes.

Recurring positives

Powder format can feel easier to fold into an evening routine than a pill.
NSF Certified for Sport stands out to athletes and certification-focused shoppers.
Some users like having a clearly labeled bisglycinate product instead of a vague blend.

Recurring negatives

Taste can feel too sweet or tart for people who wanted a neutral powder.
Mixing a scoop is less convenient than swallowing a simple capsule.
The premium price is a common sticking point when a basic glycinate option seems good enough.

Overall read

User chatter is driven more by taste, routine fit, and value than by dramatic effect claims.
This is the kind of product people either love for format and certification or skip on price alone.

Public threads reviewed: Thorne magnesium, good pure magnesium bisglycinate, magnesium bisglycinate and sleep.

Note: These are summarized recurring themes from public user discussions. They are anecdotal and do not replace clinical evidence or professional guidance.

Better alternatives or compare this instead

If you like the idea of magnesium bisglycinate but not the price or sweetened powder format, the first thing to compare is a plain magnesium glycinate capsule or tablet. For many readers, that is the simpler and cheaper way to get the same general form category without paying extra for drink mix format and sport certification.

If you are not committed to glycinate, compare forms before brands. Some readers end up deciding that a different form is a better fit for budget, digestion, or use case. Our side-by-side guides on magnesium glycinate vs citrate and magnesium citrate vs oxide are often a better next step than choosing between premium labels.

And if you are still early in the process, you may be better served by the parent magnesium guide rather than this product page. That is especially true if you are asking broad questions like which form to start with, how much to take, or whether you even need a supplement at all.

Alternatives at a glance

Product	Best For	Main Tradeoff
NOW Magnesium Glycinate Tablets	Value tablet shoppers	Tablet burden and longer ingredient list.
Doctor's Best High Absorption Magnesium	Lowest cost per serving	Less premium feel and weaker certification story.
Magnesium Guide	Form-first decisions	Less product-specific if you are ready to buy now.

FAQ

Short answers to the questions readers most often ask before taking the next step.

Is Thorne Magnesium Bisglycinate the same as magnesium glycinate?

It is in the same form family people usually mean when they say magnesium glycinate. The product listing specifically names magnesium as magnesium bisglycinate.

How much magnesium is in one serving?

One scoop provides 200 mg magnesium, according to the current public iHerb listing.

Is this product third-party certified?

Yes. Public NSF search results list it as NSF Certified for Sport. If you want to understand how that differs from other verification language, see what third-party tested means and USP vs NSF.
