Both list 5 g creatine monohydrate per serving. NSF’s sport listing adds banned-substance screening, but the current Signature Spec jar should match the listed product and lot.

Naked Creatine
Unflavored · 500 g · 100 servings
5gcreatine monohydrate per serving
Why it’s hereA bigger tub of plain creatine: 100 servings, compared with Momentous’s 90. It’s also NSF Contents Certified.
Worth knowing NSF Contents Certified and Certified for Sport are different programs. The label’s 5 g serving does not tell you how much you personally need.
Label details
5 g creatine monohydrate per serving. One ingredient.
Ingredients: Creatine monohydrate
NSF Contents Certified: NSF’s contents program (NSF/ANSI 173) lists Naked Creatine powder with a 5 g scoop. This is not an NSF Certified for Sport listing. Check the NSF listing (opens in a new tab) Checked September 3, 2026.
Why it’s hereNSF lists Momentous unflavored 450 g powder and specific lots in its Certified for Sport program, which includes banned-substance testing.
Worth knowing The current jar says Signature Spec, while NSF’s linked label still says Creapure. Match the package and lot number to the current listing before relying on certification.
Label details
5 g creatine monohydrate per scoop. No other ingredients listed.
Ingredients: Creatine monohydrate
NSF Certified for Sport: NSF lists US unflavored 450 g powder with a 5 g scoop and specific lots. The current Signature Spec jar differs from NSF’s linked Creapure label, so match the package and lot before relying on the listing. Certification does not promise better results. Check the NSF listing (opens in a new tab) Checked October 2, 2026.
Both powders list 5 g creatine monohydrate per serving. Naked has the bigger tub. NSF’s sport listing names Momentous unflavored 450 g powder and specific lots; match the current Signature Spec package and lot before relying on it.
Compare the amount per tub
Naked has 500 g of creatine; Momentous has 450 g. Momentous needs to cost 10% less per tub to match Naked’s cost per gram. Naked costs 10% less per gram when both tubs have the same total price.
This math uses the amount on each label. Check the current prices and include shipping for both tubs. A lower cost per gram does not tell you how well a product will work.
Products we looked at (3 products)
Naked’s 500 g tub has NSF contents certification. Momentous and Thorne both have unflavored 450 g powders listed in NSF’s sport program. We haven’t found a reason to put one of those two ahead of the other.
Naked Nutrition — Naked Creatine
On the shortlist · Unflavored · 500 g · 100 servings
A bigger tub of plain creatine: 100 servings, compared with Momentous’s 90. It’s also NSF Contents Certified.
NSF Contents Certified and Certified for Sport are different programs. The label’s 5 g serving does not tell you how much you personally need.

Momentous — Momentous Creatine
On the shortlist · Unflavored · 450 g · 90 servings
NSF lists Momentous unflavored 450 g powder and specific lots in its Certified for Sport program, which includes banned-substance testing.
The current jar says Signature Spec, while NSF’s linked label still says Creapure. Match the package and lot number to the current listing before relying on certification.
Last checked September 3, 2026. Label checked September 2, 2026.
Thorne — Creatine
Not listed · Unflavored powder · 450 g · 5 g scoop
The same tub size as Momentous, with sport certification too. Those similarities are why we haven’t added a third creatine to the shortlist. We found no reason to call Momentous better.
Thorne identifies this as creatine monohydrate. NSF lists the unflavored 450 g powder with a 5 g scoop in Certified for Sport.
Check your package and lot number against NSF’s record. We haven’t tried the powders or compared current prices to choose between them.
Why it’s herePlain whey concentrate you can add to a smoothie or recipe. There’s no added flavor or sweetener. NOW’s unflavored isolate comes in a smaller tub.
Worth knowing Contains milk. This is a whey concentrate; the isolate alternative also contains milk.
Label details
25 g protein per 30 g serving, about two scoops.
Ingredients: Whey protein concentrate. Contains milk.
One whey pick so far. Naked’s unsweetened concentrate comes in a 5 lb tub; NOW’s unflavored isolate comes in a 1.2 lb tub. Both contain milk. See the comparison below.
Naked’s concentrate comes in a 5 lb tub with one ingredient. NOW and Klean have smaller unflavored isolate packs with sunflower lecithin. Klean’s US 446 g pouch is listed in NSF’s sport program. All contain milk and none list a sweetener.
Naked Nutrition — Naked Whey
On the shortlist · Unflavored · 5 lb · 76 servings
Plain whey concentrate you can add to a smoothie or recipe. There’s no added flavor or sweetener. NOW’s unflavored isolate comes in a smaller tub.
Contains milk. This is a whey concentrate; the isolate alternative also contains milk.
Last checked September 3, 2026. Label checked September 2, 2026.
NOW Sports — Whey Protein Isolate
Not listed · Unflavored · 1.2 lb · about 19 servings · SKU 2172
Worth a look if you want isolate or a smaller tub. We included Naked for its one-ingredient concentrate. NOW offers another way to buy unflavored whey; we aren’t calling Naked the better protein.
24 g protein per 28 g scoop. Ingredients: whey protein isolate and less than 1% sunflower lecithin. Contains milk. No flavor or sweetener is listed. This 1.2 lb tub is smaller than Naked Whey’s 5 lb tub.
Contains milk. The brand mentions certifications on its page; we haven’t confirmed those with the certifiers.
Last checked September 3, 2026. Label checked September 3, 2026.
Klean Athlete — Klean Isolate
Not listed · Unflavored · 446 g · about 20 servings · KA57534P-446
An unflavored isolate in a smaller pouch, with sport certification. We included Naked for its one-ingredient concentrate. Klean offers a different form and pack size; those differences do not show which protein works better.
20 g protein and 85 calories per scoop of approximately 22.3 g. The 446 g pouch provides approximately 20 servings. Ingredients: whey protein isolate (from milk) and sunflower lecithin. Contains milk. No flavor or sweetener is listed. NSF Certified for Sport lists the United States, Unflavored, 446 g Klean Isolate with a 22.3 g scoop.
Contains milk. Match the US unflavored 446 g pouch and its lot number to NSF’s record. The listing does not establish certification for every flavor, package or lot, or prove better health or exercise results. We haven’t tried it or compared current prices.
Naked’s label lists 26 g protein per 30 g powder. The Optimum Nutrition comparison is on hold because its selected pack and displayed nutrition label disagree. More protein in the same amount of powder does not prove it works better.

Naked Nutrition
Naked Casein
Unflavored · 5 lb · 76 servings
26gprotein per 30 g serving
Why it’s hereAdd your own flavor to this unsweetened casein. Naked recommends a blender because the powder has no lecithin to help it mix.
Worth knowing Contains milk. A 5 lb tub is a bigger commitment than the smaller Optimum Nutrition option, whose package details are being rechecked.
24gprotein per serving on the older 27-serving label
Why it’s hereA vanilla-flavored alternative to Naked’s plain casein. We are keeping the earlier label information visible while checking conflicting package details on the brand’s page.
Worth knowing Contains milk and soy on the displayed older label. The selected pack and nutrition image disagree; confirm the current container label before buying.
Package conflict checked September 30, 2026: the linked Creamy Vanilla option says 25 servings (1.81 lb), but its nutrition image still shows 27 servings (2 lb). We are not calculating a current-pack protein-density comparison until the label is confirmed.
Label details
The displayed older 27-serving label lists 24 g protein per 33 g serving, about one scoop. We have not confirmed this serving weight for the currently selected pack.
Ingredients: Displayed older label: micellar casein, natural and artificial flavors, inulin, salt, gum blend (cellulose gum, xanthan gum, carrageenan), lecithin, sucralose, protease, Yellow 5. Contains milk and soy. Check the current container before buying.
Naked is unsweetened and comes in a 5 lb tub. Optimum Nutrition is vanilla flavored, but its current package and displayed label disagree. Both displayed labels contain milk.
Products we looked at (3 products)
Naked is unsweetened and the brand recommends a blender. Optimum Nutrition’s vanilla casein is on hold because its current pack and displayed label disagree. Kaged also sells vanilla casein, but we still need to confirm all the label details.
Naked Nutrition — Naked Casein
On the shortlist · Unflavored · 5 lb · 76 servings
Add your own flavor to this unsweetened casein. Naked recommends a blender because the powder has no lecithin to help it mix.
Contains milk. A 5 lb tub is a bigger commitment than the smaller Optimum Nutrition option, whose package details are being rechecked.
Last checked September 3, 2026. Label checked September 2, 2026.
Optimum Nutrition — Gold Standard 100% Casein
On hold — conflicting package details · Creamy Vanilla · package details under review
A vanilla-flavored alternative to Naked’s plain casein. We are keeping the earlier label information visible while checking conflicting package details on the brand’s page.
Contains milk and soy on the displayed older label. The selected pack and nutrition image disagree; confirm the current container label before buying. Package conflict checked September 30, 2026: the linked Creamy Vanilla option says 25 servings (1.81 lb), but its nutrition image still shows 27 servings (2 lb).

Kaged — Casein
Needs another check · Vanilla · 2 lb · 28 servings shown on the product image
Another vanilla casein in a 2 lb tub. We haven’t added a link to buy it because we still need to confirm the full Vanilla ingredients and serving weight from a readable current label.
The manufacturer describes 25 g micellar casein protein per serving. Informed Sport’s directory includes Kaged Casein and lists tested Vanilla batches.
We couldn’t read the label image clearly. Informed Sport lists specific Vanilla batches, so check the number on your package. That record doesn’t fill in the missing ingredient details.
One electrolyte pick so far. LMNT has more sodium than the Nuun tablet below. More isn’t automatically better. We’re still confirming Liquid I.V.’s label before adding a link to buy it.
Products we looked at (3 products)
LMNT has 1,000 mg sodium and no sugar per stick. Nuun Sport has 300 mg and 1 g sugar per tablet. Liquid I.V.’s original version also contains sugar; we still need to confirm the amounts on its current label.
LMNT — Zero-Sugar Electrolytes
On the shortlist · Citrus Salt · 30 sticks
A stick you can toss in your bag, with no sugar. It has 1,000 mg sodium, compared with 300 mg in a Nuun Sport tablet.
Sweetened with stevia. This is not a low-sodium mix; check any sodium limit your clinician has given you.
Last checked September 3, 2026. Label checked September 2, 2026.
Nuun — Sport
Not listed · Lemon Lime · 10-tablet tube · 1 tablet (5 g) per serving
Less sodium than LMNT, in a tablet you dissolve. LMNT is on the shortlist for its zero-sugar, 1,000 mg-sodium stick. Nuun is worth a look if you want less sodium and don’t mind the 1 g sugar.
300 mg sodium, 150 mg potassium, 25 mg magnesium and 1 g sugar per tablet. A dissolving tablet in a tube, with dextrose and stevia among the ingredients.
Lower than LMNT does not mean low-sodium. These figures compare one tablet with one stick; the water you mix them into can differ. Neither number tells you how much sodium you need.
Last checked September 3, 2026. Label checked September 3, 2026.
Liquid I.V. — Hydration Multiplier
Needs another check · Lemon Lime · original version with sugar · 16 sticks
This version contains sugar. We couldn’t read the current nutrition label clearly enough to confirm the amounts of sodium and sugar or the serving weight. We haven’t added a link to buy it yet.
The brand’s page shows a 16-stick Lemon Lime pouch and lists cane sugar and dextrose as ingredients. This is the original Hydration Multiplier. The Sugar-Free version is sold separately.
We won’t fill the gaps with numbers from older labels. Sugar alone isn’t a reason to call this product unhealthy.
Why it’s hereA smaller bottle of glycinate capsules: 60, compared with Pure Encapsulations’ 90. Each capsule has 100 mg magnesium; two make the 200 mg serving on the label.
Worth knowing Two capsules make one serving. Ask a clinician about medication use or kidney disease.
Label details
200 mg magnesium as magnesium bisglycinate per two capsules.
One magnesium pick so far. Nature Made has the smallest bottle of the three products below. Compare the form and amount per capsule or tablet too; the label cannot tell you which dose you need.
Products we looked at (3 products)
Nature Made has 100 mg magnesium per capsule; Pure Encapsulations has 120 mg. NOW’s citrate tablet has 200 mg. Check how many capsules or tablets make a serving. The number on the label doesn’t tell you how much you need.
Nature Made — Magnesium Glycinate
On the shortlist · 200 mg · 60 capsules · 30 servings
A smaller bottle of glycinate capsules: 60, compared with Pure Encapsulations’ 90. Each capsule has 100 mg magnesium; two make the 200 mg serving on the label.
Two capsules make one serving. Ask a clinician about medication use or kidney disease.
Last checked September 3, 2026. Label checked September 2, 2026.
Pure Encapsulations — Magnesium (glycinate)
Not listed · 120 mg per capsule · 90 capsules · order code MG9
A larger bottle with more magnesium in each capsule. We included Nature Made for its smaller bottle. We haven’t found evidence that it works better than Pure Encapsulations.
120 mg magnesium as glycinate per capsule. Other ingredients: cellulose-and-water capsule and ascorbyl palmitate. The brand’s May 2025 ingredient sheet lists the 90-capsule MG9 bottle. Nature Made’s bottle here has 60 capsules.
Nature Made has 100 mg per capsule; two capsules make its 200 mg serving. Pure has 120 mg in one capsule. These label amounts aren’t a recommendation for how much to take.
A tablet with more magnesium per serving than Nature Made’s capsules. We included Nature Made for its glycinate form and smaller bottle. That choice doesn’t show that glycinate works better than citrate.
400 mg elemental magnesium from citrate per two-tablet serving; 200 mg per tablet. Magnesium citrate in a 100-tablet bottle.
The 200 mg on the front is per tablet. A full serving is two tablets. Ask a clinician about medication use, kidney disease or how much to take.
