The best Pure Encapsulations alternatives are Thorne and Momentous (both NSF Certified for Sport), Doctor's Best (lowest per-milligram price we computed), Seeking Health, Vital Nutrients, Transparent Labs, Designs for Health, Jarrow, NOW and Ritual. Among the magnesium products we could price, costs run from $0.10 to $0.43 per 100 mg of magnesium.
Some Reddit commenters call Pure Encapsulations top quality. Reddit commenters raise price and ownership as reasons to look elsewhere. We compared one product category, magnesium glycinate or bisglycinate (or the nearest blend), and put prices on a per-100 mg basis where we could.
How we picked these brands
- A comparable magnesium product. Each brand has a matched magnesium glycinate or bisglycinate product (or the nearest equivalent), so cost can be compared where a price and milligram amount were available. Designs for Health and Ritual could not be compared.
- Price per 100 mg of elemental magnesium. We used list price for one container with no subscription discount, checked 2026-10-16. This is a cost comparison, not a quality ranking.
- What the brand's own magnesium page says about testing. We note whether a third-party testing statement appears on the page we checked. Absence on a page does not mean a product is untested.
- A real storefront. We looked for a working storefront with product pages.
Why shoppers look for alternatives
Price is one reason shoppers give. On magnesium, Thorne's list price per 100 mg is higher than Pure Encapsulations, so it is not a budget swap.
Ownership is the second reason. A commenter on r/Supplements wrote: "Some people seem to have an issue with Pure Encapsulations being owned by Nestle." Nestlé Health Science owns the brand through its purchase of Atrium Innovations, according to Nestlé's press release.
For reference, Pure Encapsulations Magnesium (glycinate) costs $27.00 for 90 capsules of 120 mg each, or $0.25 per 100 mg. Its magnesium page lists a long free-from list (wheat, gluten, magnesium stearate and more) but does not mention third-party testing, as of 2026-10-16. You can buy it without a practitioner at the brand's consumer store, pureforyou.com.

Prices are list price for one container as of 2026-10-16. Seeking Health's figure is for Optimal Magnesium, a malate and lysinate glycinate chelate blend. The Vital Nutrients figure is for a glycinate and malate blend. The NOW figure is a Vitacost price, not a brand-site price.
1. Thorne
Thorne's magnesium bisglycinate powder is NSF Certified for Sport, and the brand's homepage says it runs a minimum of four rounds of testing on every product. It is gluten, dairy and soy free.
At $52 for 60 scoops of 200 mg each, it is the most expensive in our set at $0.43 per 100 mg, about 1.7 times Pure Encapsulations. Pick it if drug-tested certification matters. Skip it if price is your reason for leaving.
2. Designs for Health
Retailer listings show its Magnesium Glycinate Complex at 150 mg per capsule, and the brand page makes absorption claims without naming a study in the text we saw.
The price is not published on the brand page, so we could not compute a cost per milligram. It suits people already working with a nutritionist or functional-medicine provider, and it is a poor fit if you want to compare prices before you buy.
3. Seeking Health
Seeking Health is formulated by Dr. Ben Lynch and is known for active-form B vitamins and a methylation focus. Optimal Magnesium is $22.00 for 100 capsules at 150 mg each, or $0.15 per 100 mg. Its product page carries a "Third Party Tested" banner, though no testing body is named.
Choose it if you are in the MTHFR and methylation crowd or sensitive to B-vitamin form. Its pure Magnesium Glycinate is a $37.00 powder, so go there only if you want a single form.
4. Vital Nutrients
Vital Nutrients presents itself as trusted by healthcare practitioners and runs a Practitioner Portal. Its Magnesium Glycinate + Malate is $24.99 for 100 capsules, or $0.21 per 100 mg, and it is a blend rather than pure glycinate.
It is the pick for a practitioner-line brand at a mid price. The quality page we checked makes no third-party testing claim, so buyers who need certification should look at Thorne or Momentous instead.
5. Momentous
Momentous states that every batch of its Magnesium Bisglycinate is third-party tested and NSF Certified for Sport. It uses no proprietary blends and delivers 200 mg of elemental magnesium per two capsules.
At $16.99 it works out to $0.28 per 100 mg, a little above Pure Encapsulations and below Thorne (the $16.99 price carried a 25% Off badge with no list price shown). Take Momentous over Thorne if you want the same NSF Sport certification and the Momentous price as we saw it (with the 25% Off badge) works for you.
6. Transparent Labs
Transparent Labs gives full access to its third-party test results, with links to a Certificate of Analysis, and its magnesium bisglycinate delivers 300 mg per serving. The price is $16.99 for 30 servings of three capsules, or $0.19 per 100 mg.
It fits shoppers who want to read lab results before buying. It is less convenient if you want one capsule a day, since a serving is three.
7. Doctor's Best
Doctor's Best describes its tablets as made with Albion TRAACS chelate technology, labeled "100% Chelated," non-GMO, gluten free, soy free and vegan. At $23.99 for 240 tablets (200 mg per two), it costs $0.10 per 100 mg, the lowest we computed and 40% of what Pure Encapsulations costs.
Pick it for the lowest per-milligram price we computed, from a tablet that names its chelate. The magnesium page does not state third-party testing, so athletes should look at Thorne or Momentous.
8. Jarrow Formulas
Jarrow was founded in Los Angeles in 1977, according to the brand. Its Magnesium Glycinate is $24.99 for 90 vcaps, about $0.23 per 100 mg, using a milligram figure from a retailer listing.
The brand page describes it as gentle on the stomach. Pick it as an established formulator; the retailer-based figure puts it slightly below Pure Encapsulations. The product page shows no milligram amount or testing statement.
9. NOW Foods
Per retailer pages, NOW Foods has been family-owned since 1968 and lists its products as non-GMO and vegan. Its Magnesium Glycinate tablets provide 200 mg per two tablets from Albion magnesium bisglycinate, 90 servings in a 180-tablet bottle.
At $19.59 from Vitacost, that is about $0.11 per 100 mg. We could not capture the brand-site price, so treat the figure as a retailer price. It suits value shoppers who want a familiar name.
10. Ritual
Ritual's Magnesium+ pairs magnesium bisglycinate with tart cherry, and the brand describes an emphasis on ingredient traceability. The brand is subscription-led. The price is $56.82, but servings and milligrams were not on the page text, so it cannot be compared per milligram.
Take Ritual if you want a sleep-oriented blend and don't mind a subscription. Leave it if you want a plain magnesium glycinate at a low cost.
How to choose
- Drug-tested athlete: Thorne or Momentous. Momentous costs less per milligram.
- Lowest per-milligram price we computed: Doctor's Best, then NOW Foods (a retailer price).
- Practitioner-line feel: Vital Nutrients or Designs for Health.
- Published lab results: Transparent Labs.
- A sleep blend: Ritual.
