Creatine, vitamin D, fish oil and magnesium: what a third-party tested stack costs a month

Creatine, vitamin D, fish oil and magnesium from NSF-listed makers cost about $83 a month with our guide picks and Thorne’s vitamin D, and about $47 at the lowest price per day of each (the vitamin D can’t be ordered from the maker; $51 with Thorne’s). We priced twelve supplements per label serving. This page prices them. It doesn’t say you should take any.

By Explainer Updated

The bottom line

The guide-pick stack, with Thorne D-5,000 because vitamin D has no pick, is about $83 a month at list price. That capsule’s 5,000 IU is above NIH’s 4,000 IU upper limit. The $47 stack has a smaller fish oil serving, the thinnest certification and a vitamin D we couldn’t order.

What does a creatine, vitamin D, fish oil and magnesium stack cost a month?

About $83 a month, or $993 a year, with the products in our supplements guide plus Thorne D-5,000 for vitamin D. That’s each product’s one-time list price at its label serving, before tax and shipping. The guide has no vitamin D pick. Nordic Naturals’ gummies had no Add to Cart button when we checked, so Thorne’s capsule stands in. Its 5,000 IU is above NIH’s 4,000 IU adult upper limit; see the upper-limits section12.

The lowest-cost stack takes the lowest price per day in each category: Momentous Creatine, Klean Omega, BulkSupplements’ magnesium and Nordic’s vitamin D3 gummies. It comes to about $47 a month, or $560 a year. Each of those carries a catch, set out below: a smaller fish oil serving, the thinnest certification, and a vitamin D that wasn’t for sale on the maker’s page.

Fish oil is the biggest line in both stacks. Doses differ between products, so a lower price per day can also mean less in the serving. A month here is one twelfth of the yearly cost. Whether any of the four does anything for you is covered in our supplements evidence review. This page prices them and gives no dose advice.

Creatine: Thorne is the guide pick, Momentous costs about $4 a year less

At one 5 g scoop a day, Thorne Creatine costs about $0.49 a day, or $178.44 a year at its $44 list price for 90 servings3. It’s the guide’s creatine pick. Momentous Creatine is $42.99 for 90 servings, about $0.48 a day and $174.35 a year, so the gap is about $44.

Klean Creatine costs more. At $34.50 for about 60 servings it’s about $0.58 a day and $209.88 a year5. Klean’s price was read on Nov 6. Thorne’s 180-serving tub lists at $84, about $0.47 a serving, which is only about two cents a serving less than the 90-serving tub3.

Klean Creatine5 g (1 scoop), about 60 servings$34.50, Nov 65$0.58$209.88

Vitamin D: Thorne D-5,000 was the one you could order, Nordic’s gummies cost less a day

No vitamin D is a guide pick, so this page uses the two we reviewed. Thorne D-5,000 is $20 for 60 capsules on Thorne’s page. At one capsule a day that’s about $0.33 a day, or $121.67 a year1. The 120-capsule bottle lists at $39, a little under a cent less per capsule1.

Nordic Naturals lists its Vitamin D3 Gummies Sport at $23.95, and its page gives no gummy count. NSF lists 120 gummies, which would make it about $0.20 a day and $72.85 a year6. On Oct 13 the page had no Add to Cart button, so you couldn’t buy them there, and we haven’t rechecked.

The servings aren’t the same size. The Nordic gummy is 1,000 IU (25 mcg) of vitamin D3 and the Thorne capsule is 5,000 IU (125 mcg)12. The per-day prices compare each product at its own label serving, not equal amounts. The upper-limits section below puts those doses next to NIH’s figure.

Vitamin D at one label serving a day
ProductLabel servingList pricePer dayPer year
Thorne Vitamin D-5,0005,000 IU (125 mcg), 1 capsule, 60 per bottle$20, Nov 61$0.33$121.67
Nordic Naturals Vitamin D3 Gummies Sport1,000 IU (25 mcg), 1 gummy, 120 per bottle per NSF and Fullscript$23.95, Oct 13, no Add to Cart2$0.20$72.85

Fish oil: the biggest line, and Klean’s low daily price buys a smaller serving

Fish oil is the largest cost in every stack here. Momentous Omega-3 is $39.99 for 60 softgels, and two a day is about $1.33 a day or $486.55 a year7. It’s the guide’s fish oil pick, with 800 mg EPA and 800 mg DHA per two softgels.

Klean Omega has the lowest daily price. $44.50 for 60 softgels at one a day is about $0.74 a day and $270.71 a year8. A Klean softgel holds 500 mg EPA and 250 mg DHA, 750 mg together. Per gram of EPA plus DHA, Momentous is about $0.83, Nordic about $0.93 and Klean about $0.99, so Klean’s lower daily price comes with a smaller serving.

Nordic Naturals Ultimate Omega 2X Sport is $55.95 for 60 softgels. Two a day is about $1.87 a day and $680.73 a year, for 1,125 mg EPA and 875 mg DHA a serving9. Both prices were read on Nov 6. The full comparison is in best fish oil supplements.

Klean Omega1 softgel, 60 per bottle$44.50, Nov 68$0.74$270.71750 mg

Magnesium: the widest range, from $0.11 to $0.87 a day

Momentous Magnesium Bisglycinate is the guide’s magnesium pick: $16.99 for 60 capsules, two a day for 200 mg of elemental magnesium, about $0.57 a day and $206.71 a year10. Thorne Magnesium Bisglycinate gives the same 200 mg in a scoop. At $52 for 60 scoops it’s about $0.87 a day and $316.33 a year11.

The two lower prices come with different servings. Klean Magnesium is $26.50 for 90 capsules of 120 mg each, about $0.29 a day and $107.47 a year at one capsule12. Klean’s directions run from one to four capsules a day, and four would cost about $429.89 a year. BulkSupplements’ 500 g bag is $25.97 for about 227 servings of 300 mg, about $0.11 a day and $41.76 a year13. Its label declares magnesium glycinate and magnesium oxide, not glycinate alone.

Per 200 mg of magnesium, the cost is about $0.08 for BulkSupplements, $0.49 for Klean, $0.57 for Momentous and $0.87 for Thorne. The BulkSupplements price has the thinnest certification of the twelve, covered next. The full comparison is in best magnesium glycinate supplements.

Where a certifier listing covers your container and where it doesn’t

All twelve products are in NSF’s Certified for Sport database, which NSF says covers banned substances, label match, contaminants and a GMP-certified facility14. We read each listing on Nov 6. The price isn’t the whole story, because listings differ in whether a lot number lets you check your own container and whether they cover the size priced here.

Nine list lot numbers you can match to your container. Momentous Omega-3 and Momentous Magnesium Bisglycinate show lot “All”, so there is no number to look up. BulkSupplements’ magnesium lists one lot, for a 1 kg package, and the bag priced here is 500 g. For the full lookup of all 17 supplements we reviewed, see are supplements third-party tested.

That bears on the lowest-cost stack. Its magnesium is the BulkSupplements entry, and its vitamin D gummy sits under two listing codes with different lots. The guide-pick stack has lot lists for Thorne’s two products and a lot “All” listing for both Momentous ones.

Upper limits from NIH, for context

NIH’s Office of Dietary Supplements lists 4,000 IU (100 mcg) a day as the tolerable upper intake level for vitamin D in adults33. Thorne D-5,000’s capsule is 5,000 IU, above that level in a single capsule1. Nordic’s gummy is 1,000 IU2.

For magnesium, NIH lists 350 mg a day as the adult upper limit for magnesium from supplements and medications, not from food34. A Momentous or Thorne serving is 200 mg, a BulkSupplements serving 300 mg and a Klean capsule 120 mg. Klean’s directions allow up to four capsules, which is 480 mg1013.

These are NIH’s limits, not our advice on how much to take, and this page makes no dose recommendation. How much suits you depends on your diet, medicines and health, which is a question for your clinician. The evidence review covers what studies found for each of the four.

How current the prices are

The Thorne, Momentous and BulkSupplements prices, all three Klean prices and the Nordic Naturals Ultimate Omega 2X Sport price were read on Nov 6. The Nordic Naturals Vitamin D3 Gummies Sport price was read on Oct 13 and hasn’t been rechecked, so the lowest-cost stack’s vitamin D line carries the oldest date.

Every price is a one-time list price before tax and shipping. Subscription discounts exist and aren’t counted, such as Momentous’s 25% off the first delivery and 10% off later ones7. Prices change, so each product’s own page has the current figure.

How we worked out the numbers

Each figure comes from the product’s review: its list price on the maker’s page, the label serving and the servings per container. The reviews carry the sources and the dates.

  • Per day is the list price divided by the servings in the container, at the label serving.
  • Per year is 365 days of refills at that price, with no subscription discount, coupon or sale price.
  • Per month is one twelfth of the yearly figure.
  • To start is the price of one container of each product in the stack.
  • Stacks are sums of the same product figures, so they move when any one price does.
