Two containers sit side by side. One promises 350 mg of magnesium. The other lists 200 mg and looks about half as big. If you picked the larger number, would you get a better buy? With these two Codeage products, the answer changes depending on whether you care about magnesium per serving, how many servings you buy, or how much money leaves your wallet today.
For a quick decision, the powder supplies 200 mg of elemental magnesium per labeled serving and avoids swallowing several capsules. The capsules supply 350 mg per four-capsule serving and travel without a scoop. Both facts matter more than the word “liposomal” on the front. Neither format is a universal winner for absorption, sleep, or comfort. The differences you can actually verify are on the back panel and in the routine you will use.
Read the mineral line before the front label
Look for the line that begins with “Magnesium” under Supplement Facts. The number at the right is the weight of the magnesium itself in one serving. The words in parentheses identify where it comes from. A package that lists magnesium from bisglycinate chelate does not ask you to count the entire weight of the chelate as magnesium. This distinction lets you compare different compounds without a chemistry degree. NIH Office of Dietary Supplements magnesium fact sheet
Try reading the panel in reverse order. First say the unit, usually milligrams. Next read the amount. Then move up to the line that specifies the serving size. “350 milligrams in four capsules” communicates something quite different from “350 milligrams in a capsule.” Only after those numbers are clear is it worth asking how large the bottle is, whether you like the ingredients, and how the manufacturer suggests taking it.
Powder brings another number into the picture. The net weight on the front describes everything inside the container. The Codeage jar holds 85.2 grams of powder. That includes the compound that supplies magnesium and other ingredients in the formula. Dividing 85.2 grams by 200 milligrams does not give the number of servings. Those figures describe different things. The manufacturer lists approximately 60 servings. That is the number to use for budgeting.
Two Codeage labels side by side
| What to compare | Magnesium glycinate powder | Magnesium glycinate capsules |
|---|---|---|
| Mineral per labeled serving | 200 mg | 350 mg |
| Serving reference | 1.42 g of powder on the recorded panel | 4 capsules |
| Packages compared | 85.2 g, about 60 servings | 120 capsules, 30 servings, or 240 capsules, 60 servings |
| What else to check | Directions, scoop size and flavor ingredients | Magnesium sources, capsule shell and black pepper extract |
| Most practical difference | Needs measuring and mixing | Needs no drink preparation beyond water for swallowing |
The Codeage magnesium glycinate powder lists bisglycinate chelate as the magnesium source. On the 85.2 g label recorded by NIH, one listed serving weighs 1.42 g. Codeage’s directions describe the amount to mix using its supplied scoop. A kitchen teaspoon is not calibrated to that scoop. If an online listing and your jar describe the scoop differently, check the printed serving weight and ask the manufacturer to reconcile the directions before measuring.

The Codeage magnesium glycinate capsules in our catalog list both magnesium bisglycinate chelate and magnesium oxide as sources of the 350 mg total, plus black pepper extract. The panel does not break out how much elemental magnesium comes from each source. If you specifically want a formula without oxide, that is a meaningful distinction. Confirm the panel on the bottle size you select. A larger package can look nearly identical online. Codeage capsule details
What a dollar buys in each package
At the store prices checked November 2, 2026, the powder and 120-count capsule bottle were both $29.99. The powder supplies about 60 labeled servings, or roughly 50 cents each. The smaller capsule bottle supplies 30 labeled servings, or about a dollar each. The larger 240-count bottle was $39.99 and also supplies 60 servings, which works out to about 67 cents per serving. These are one-time item prices before tax or shipping.
There is a second way to compare the same purchase. Sixty powder servings at 200 mg each provide approximately 12,000 mg of labeled elemental magnesium across the jar. Thirty capsule servings at 350 mg provide 10,500 mg across the small bottle. Sixty of those servings provide 21,000 mg across the large bottle. Someone looking solely at cost per labeled serving picks the powder. Someone comparing cost per 100 mg gets a different answer for the large capsule bottle.
Divide the price by the total number of 100 mg units. Using the prices above, that comes to about 25 cents for the powder, 29 cents for the small capsule bottle, and 19 cents for the large capsule bottle. This is shopping arithmetic. It does not establish that a larger serving suits you or that the least expensive mineral is the one your body absorbs best. A bottle you dislike using can still be a poor purchase at 19 cents.
What powder changes in a real kitchen
Picture a weekday morning. You have water, a glass and time to stir something at home. A powder may fit easily, particularly if several large capsules are difficult to swallow. You also get to see how the product disperses and whether its flavor works for you. A scoop that sticks in the back of a drawer or gets swapped with one from a protein tub makes accurate measuring harder. Keep the supplied scoop and its jar together.
For a traveler, the tradeoff can reverse. With capsules, there is no powder to spill in a suitcase and no scoop to find in a hotel room. Four capsules per labeled serving still deserve an honest look. If swallowing one capsule is already difficult, putting four in a travel container does not solve the problem. If you travel with either format, keep enough of the original packaging to identify the product, ingredients and directions.
A powder also has ingredients that help it mix or affect the taste. Read the complete ingredient list on the exact version offered. “Unflavored” can describe a product without a named flavor while leaving room for ingredients that influence taste. Capsule labels have their own details, including the material used for the shell. If you have a specific ingredient to avoid, use that as a filter before you calculate a price.
Add the rest of your day to the calculation
It is surprisingly easy to buy magnesium twice. An electrolyte drink might provide some, a multivitamin might supply more, and certain antacids or laxatives contain magnesium as well. Lay out the products you actually use on the same day. Copy the amount per serving for each and multiply by the number of servings you use. A mineral that appears near the bottom of a multivitamin panel still belongs in the sum.
For example, imagine an electrolyte mix with 60 mg of magnesium and a multivitamin with 80 mg. Together they account for 140 mg. Adding a 200 mg powder serving brings the hypothetical supplemental total to 340 mg. Adding a 350 mg capsule serving instead brings it to 490 mg. Neither result tells you how much magnesium you need. It does show why swapping two packages with the same ingredient name deserves another look at the numbers.
For adults, NIH lists a tolerable upper intake level of 350 mg a day from supplemental and medicinal magnesium. Magnesium that occurs naturally in foods does not count toward this upper limit. The limit is separate from the recommended dietary allowance, which counts food too. An adult capsule serving containing 350 mg already reaches that general upper limit before other supplemental sources are counted. Anyone whose clinician has recommended a different amount should clarify how all sources fit into that plan. NIH magnesium guidance for consumers
Does one form work better for sleep or digestion?
If better sleep is the reason you landed here, the two product labels cannot settle that question. Both identify amounts and ingredients. Neither provides a head-to-head test of these exact products for your sleep concern. Sleep changes from week to week with schedule, stress and other factors. A night when you fall asleep quickly after trying a powder is a real experience, but it cannot tell you which ingredient helped or how a capsule would have compared.
Tolerability has a more immediate bearing on the purchase. Supplemental magnesium can cause diarrhea, nausea or abdominal cramping, especially at higher intakes. A comparison between a 200 mg powder serving and a 350 mg capsule serving changes both the format and the amount. If one feels different, you cannot isolate the cause from that experience alone. Take the labels to a pharmacist or clinician if you need help finding an appropriate amount or if symptoms persist.
Certain antibiotics and oral osteoporosis medicines can interact with magnesium, and kidney problems can change how safely your body handles it. If either applies, ask a pharmacist about the actual medication and timing before opening the package. A generic “take at bedtime” rule can be a poor fit for someone who already follows a carefully timed medication schedule. The NIH professional fact sheet explains the relevant medicine groups.
Common questions about magnesium glycinate powder and capsules
Does magnesium glycinate mean the same thing as bisglycinate?
Both names are used for magnesium associated with glycine. The more useful purchasing question is whether bisglycinate is the only source on the label. Some products list oxide as well. If the label groups the sources together, it tells you the elemental magnesium they supply in total. It may leave the split undisclosed. A bold “glycinate” on the front does not answer that second question.
Is there 350 mg in each Codeage capsule?
The amount in this comparison is per four-capsule serving. Dividing 350 by four gives an average of 87.5 mg per capsule for label arithmetic. It does not authorize a change to the directions. This distinction also explains why the 120-count bottle has 30 full labeled servings and the 240-count bottle has 60. Check the count before purchasing a bottle for an extended trip.
Can I compare percentages of Daily Value instead of milligrams?
You can use the percentage as a quick orientation, especially between two labels that use the same reference value. Milligrams work better when adding multiple products or discussing a clinician’s recommendation. A rounded percentage can hide small differences. Daily Value describes a general labeling reference, while an appropriate individual intake depends on factors the package does not know. Keep the actual milligrams in your notes.
Are food sources worth considering before another supplement?
Yes. Beans, nuts, seeds, whole grains and leafy greens can contribute magnesium. If your question is about meeting ordinary nutritional needs, looking at a day’s meals may help you understand whether there is a gap to discuss. A bowl of beans offers fiber and other nutrients as well. The calculation for supplemental upper limits is separate, so do not subtract the magnesium in dinner from that limit or count only pills when assessing your overall diet.
Does liposomal delivery make a lower dose equal a higher one?
There is no conversion on these labels that makes 200 mg in the powder equivalent to 350 mg in the capsule. “Liposomal” describes a formulation feature. A valid comparison of absorption would need evidence for the particular products and amounts, and an absorption result would still be separate from a sleep or comfort outcome. Use the elemental amounts shown rather than applying a multiplier from a marketing claim.
Which would you choose if cost and convenience matter equally?
Price the package you would actually finish. For someone who routinely mixes a drink and dislikes swallowing several capsules, the powder has the lowest cost per labeled serving in this comparison. For someone who travels frequently and already prefers capsules, the large bottle offers a lower cost per 100 mg at the checked prices. If neither amount fits a plan you have discussed with a professional, the right shopping decision can be to keep looking.
Browse our Magnesium collection to compare other strengths, or open the Codeage collection for the current package options. When you narrow it to two, write a single line for each with milligrams, serving size, bottle count and price. That little note is much easier to use than trying to remember which front label had the biggest number.
