NOW Foods Zinc Glycinate is the cheapest legitimate chelated zinc on Amazon — and that's the only relevant frame for evaluating it. At $9/month for a 120-softgel bottle (roughly 4 months at 30 mg/day), it sits at $0.08 per active softgel, the lowest cost-per-elemental-mg in the entire top tier of the category. The form is real bisglycinate, the dose lines up with the Prasad 1996 trial, and the brand is NOW Foods — a household name with 30+ years of in-house QC labs and a deep enough catalog that this single product isn't where their reputation rises or falls. What you give up versus the picks above: NSF Certified for Sport certification (Thorne #1) and hypoallergenic clinician-grade label discipline (Pure Encapsulations #2). For most first-time buyers neither of those gaps matters. Here's the full breakdown of what $9/month actually delivers.

Read the complete Zinc guide →Zinc bisglycinate — the same gentle top-tier chelate Pure Encapsulations (#2) ships. Two glycine molecules clamp the zinc ion through the gut wall via amino-acid uptake pathways. ~25-30% absorbability — roughly 2× zinc oxide. Maares & Haase 2020 (PMID 32079282) catalogues bisglycinate as absorption-equivalent to picolinate.
Single-softgel 30 mg elemental zinc — matches the Prasad 1996 testosterone trial dose exactly. No competing minerals in the formula. Softgel format dissolves cleanly with food and has a slight onset edge vs tablets (no disintegration phase). Sits cleanly inside the 25-30 mg productive window and well below the 40 mg/day UL.
NOW Foods runs in-house QC labs at their Bloomingdale, IL facility — among the most extensive captive testing operations in the supplement industry, with 30+ years of operational consistency. GMP-certified manufacturing, FDA-registered facility, and publishes Certificate of Analysis data on request. No NSF Certified for Sport or USP verification — the relevant gaps if you're drug-tested or want third-party label-claim auditing on top of brand QC.
$0.08 per 30 mg elemental softgel = roughly $0.003 per active mg. Cheapest cost-per-elemental-mg of any verified chelated zinc on the list. Roughly 3× cheaper than Thorne (#1) at $0.23/cap and 4× cheaper than Pure Encapsulations (#2) at $0.30/cap. The cost gap is real and doesn't reflect a meaningful difference in the zinc you absorb.
30 mg single-softgel bisglycinate matches the Prasad 1996 testosterone trial dose exactly. Lands inside the Cervantes 2019 acne RCT range (30-50 mg). Softgel format has a slight onset edge vs capsules or tablets — the gel dissolves cleanly with food, releasing the bisglycinate uniformly. Real-world responder reports cluster around standard chelate timelines (T trends at week 4-8 in deficient men, skin at week 8-12).
“Zinc bisglycinate — highly bioavailable chelated form.”
Bisglycinate is consistently identified as one of the two top-tier zinc chelates with ~25-30% absorbability (Maares & Haase 2020 PMID 32079282). The 'highly bioavailable' framing is accurate vs the oxide and gluconate forms that dominate cheaper bottles — and NOW genuinely ships bisglycinate, not a re-labelled cheaper form.
“Supports immune system function and cellular metabolism.”
Both claims trace to zinc's documented mechanisms — zinc-finger transcription factors regulate immune cell function, and zinc is a cofactor for 300+ metabolic enzymes. Accurate in spirit, but the marketing copy is structurally vague (every cell uses zinc; every supplement could make this claim). The Hemilä 2017 (PMID 28515951) immune evidence is specifically for acute lozenge protocols, not daily softgels.
“30+ years of family-owned manufacturing — NOW Foods quality.”
NOW Foods has been family-owned and operating since 1968 with continuous manufacturing in Bloomingdale, IL. The 30+ year claim is accurate and the captive manufacturing + in-house QC labs are real. Among the most operationally consistent mid-tier supplement brands in the US market.
“Softgel format for easy swallowing and gentle digestion.”
Softgels are objectively easier to swallow than tablets for users with pill aversion or swallowing difficulties, and the gel format dissolves cleanly without the disintegration phase capsules and tablets require. The gentle-digestion claim layers on top of bisglycinate's already-mild GI profile.
“Made in a GMP-certified facility with non-GMO ingredients.”
NOW manufactures in a GMP-certified, FDA-registered facility. The non-GMO claim is verified by the brand's documentation and reflected in third-party certifications. Standard at the mid-tier and consistent with NOW's broader portfolio.
Side-by-side, NOW Foods Zinc Glycinate and Pure Encapsulations Zinc 30 (#2) ship the same active molecule: zinc bisglycinate at 30 mg elemental. The clinical performance in your bloodstream is the same. What you're paying $9/month less for here is the absence of two things: clinician-grade hypoallergenic excipient discipline (NOW includes standard softgel ingredients — gelatin, glycerin, beeswax, soy lecithin) and brand pedigree positioning. For 95% of users neither matters. The molecule is the molecule, and NOW's 30+ year QC track record means you're not gambling on a counterfeit.
Thorne (#1) and Pure Encapsulations (#2) ship 60-cap bottles. NOW ships 120 softgels at the same elemental dose. At 30 mg/day that's a 4-month supply for $9, which works out to $2.25/month if you spread the cost — the lowest sustained-supplementation cost in the entire chelated zinc category. For buyers running 6-12 month protocols (Prasad 1996 timeline for full testosterone response), that's $13.50 vs $45 (Thorne) vs $54 (Pure Encapsulations) for the same elemental zinc.
The softgel shells are bovine gelatin. NOW makes a vegcap zinc product separately, but this specific Zinc Glycinate SKU is gelatin-shelled. If you're vegan, vegetarian, or follow religious dietary restrictions on bovine products, this bottle is wrong for you — Thorne (#1, vegetarian capsule), Pure Encapsulations (#2, vegetarian capsule), and Garden of Life Vitamin Code Raw Zinc (#4, certified vegan) are the right alternatives.
NOW Foods leans on captive in-house testing rather than third-party certification stamps. For non-athletes that's fine — NOW's QC track record is among the most consistent in the industry, the company has been around since 1968, and they publish COA data on request. For drug-tested athletes the gap is real: NCAA, IOC, MLB, NFL, NHL all require NSF Certified for Sport, and only Thorne (#1) carries it in this category. If you're not in a tested federation, the NSF gap is irrelevant.
The protocol doesn't change with the cheaper bottle. One softgel with a meal containing protein and fat, ideally breakfast or dinner. Avoid co-dosing with high-calcium or iron supplements — separate by 2 hours minimum. Re-test serum zinc at week 8; drop to a 15 mg/day maintenance dose once you're repleted (NOW makes a 15 mg zinc bottle for this exact transition). The bisglycinate form is gentle enough that ~95% of users will tolerate it cleanly even with mild sensitivities.
NOW Foods Zinc Glycinate is what we recommend to first-time chelated zinc buyers on a tight budget, to cost-optimisers who want a real chelate without paying for brand positioning, and to anyone running a 6-12 month deficiency repletion protocol who doesn't want to spend $50-100 on a $9 problem. The form is right (bisglycinate, top-tier chelate), the dose is right (30 mg single-softgel, matches Prasad 1996), and the QC pedigree is among the strongest in the mid-tier supplement market. What you give up — NSF certification, hypoallergenic excipient discipline — most buyers don't actually use. The two cases where you should look elsewhere: (1) you're drug-tested and need NSF Certified for Sport — Thorne (#1) is the only category answer; (2) you have documented sensitivity to common supplement excipients (mag stearate, soy lecithin) — Pure Encapsulations (#2) is the hypoallergenic answer. The third caveat: softgel shells are bovine gelatin, so vegans and vegetarians need to look elsewhere. Otherwise, this is the bottle. Run 30 mg with breakfast for 8 weeks, re-test serum zinc, drop to maintenance. Your wallet will thank you.
