Much of the price gap between supplement stores comes from whose name is on the label. A company selling its own brand sets the price itself and can run buy-more deals across its whole line. A store reselling other companies’ brands saves buyers money in other ways, through promotions, subscriptions and free-shipping minimums.
The form of the product matters as well. A plain ingredient sold by weight comes without the capsules and flavoring of a finished product, and in exchange the buyer measures out each dose at home.
How budget supplement stores keep prices low
Puritan’s Pride, Vitamin World and Myprotein lean on their own labels, so the brand on the bottle is the store’s. Vitacost, The Feed and The Vitamin Shoppe mostly resell other companies’ brands.
How the product is sold splits them a second way. PureBulk is the only store here selling single ingredients by weight, and none of the seven resells other brands in bulk. Someone loyal to name brands is better served by the resellers, and anyone after the lowest price per gram should look at house brands or bulk.
1. Vitacost
Vitacost no longer offers a subscription discount, because its Autoship program ended on June 30. It has also been part of iHerb since iHerb bought it in January 2026. Orders now ship from iHerb, and the two stores share one catalog at the same prices, so they count as one store.
Vitacost still runs deals on single brands. In October 2026, Vitacost had 25% off Honey Stinger and 20% off iHerb’s own brands. Cure Hydration, Raw Nutrition, Kaged and Force Factor were 25% off as well, and orders of $30 or more after discounts shipped free. Each promotion covers one brand, so the saving depends on whether the brand someone already takes is included at the time.
2. Puritan’s Pride
The buy-more deals at Puritan’s Pride apply only to several bottles of the same item in the same size, and nearly everything on the site is its own brand, so the deal suits staples bought in quantity. The offer rotates between versions such as buy one, get two free. Its free loyalty program, Puritan’s Perks, gives $5 back for each 1,000 points at 10 points per dollar, or about 5% back. Its online vitamin quiz takes 10% off when three or more of the items it suggests are bought together. Orders over $49 ship free. Smaller ones pay $4.95. New customers get 20% off for joining the email list or 25% off for signing up for text messages.
3. The Feed
Certification is uneven across The Feed store, where NSF Certified for Sport products share the catalog with uncertified ones. So anyone who needs tested supplements has to filter for them, for example through the store’s NSF Certified for Sport page. On that page, Momentous Creatine cost $33.96 in October 2026, down from $42.99.
Filling out an Athlete Profile brings a one-time 20% discount. The Try It program sells up to three samples, such as Transparent Labs Greens or Foundation, for $0.99 each once an order reaches $35.
4. The Vitamin Shoppe
Auto Delivery at The Vitamin Shoppe covers only select items, and its discount doesn’t combine with other offers. Where it applies, it takes 15% off most eligible brands and 20% off the store’s own brands on the first and every repeat order. Repeat deliveries also ship free once the subscribed items pass $25 after the discount. The store matches select competitors’ prices on an identical item if the buyer shows proof before ordering. The match leaves out outside sellers on Amazon and Walmart, and repeat Auto Delivery orders don’t qualify for a price match.
5. PureBulk
PureBulk sells single ingredients, mostly as plain powders, so each dose gets weighed or scooped with the scales and measuring spoons the store also sells. That takes more work than opening a bottle of capsules, and the price covers no capsules or flavoring.
The price per gram falls as the bag grows. In October 2026, its micronized creatine monohydrate cost $9.50 for 250 grams, which is about 3.8 cents a gram. The 1.5-kilogram bag cost $44.50, or about 3 cents a gram. A subscription takes 10% off repeat shipments every 30, 60 or 90 days.
Orders go out within one business day. Shipping is free from $99 after discounts, and smaller orders pay a flat $4.99.
6. Vitamin World
Vitamin World charges a flat $7.99 to ship any order under $59, and most orders that are in stock ship within a day. Its standing offer is buy one, get one 50% off on select Vitamin World brand items, so the second item is half price. Up to three can be mixed and matched in one order, and the same deal runs on select items from its Precision Engineered sports line. Through October 28, 2026, it also covers select BSN, Optimum Nutrition, Isopure and Think! products. The buy-one deal doesn’t apply to orders shipped to Alaska, Hawaii, United States territories or military mail addresses.
7. Myprotein
Myprotein sells only its own brand of protein, creatine and electrolytes, and it shows most products against a higher “was” price. Those sale prices change often, so the price on one visit is no guide to the next.
At time of checking, its unflavored creatine monohydrate cost $11.99 for 45 servings, down from $19.99, or about 27 cents a serving. A newsletter sign-up adds 5% off a first order. Other codes come through the newsletter and the app, and only one discount works on each order. Orders over $80 ship free, and below that shipping costs $7.99, or $12.99 on an order under $20.
How to tell whether a cheap supplement was tested
In the United States, supplements do not need approval from the Food and Drug Administration before they go on sale, so outside testing is the main check a buyer can look for, whatever the price. NSF Certified for Sport is one such program. A certificate of analysis for the batch is another, and PureBulk says it sends products to third-party laboratories and has one for every batch, so it can be checked before ordering.
For everyday vitamins, price per serving is a fair basis for choosing a store. For an athlete subject to drug testing, certification comes first, and the savings models above matter only among products that already have it.
