Frequently Asked Questions
What is the difference between magnesium glycinate, citrate, malate, and oxide?
Magnesium glycinate (bisglycinate) is the chelated form where magnesium is bonded to two glycine amino acids: it is the most-bioavailable form, the gentlest on the stomach, and the positioning anchor for sleep, calm, and anxiety. Magnesium citrate is bonded to citric acid: it is well-absorbed but pulls water into the gut (laxative effect at higher doses), which positions it for constipation lanes. Magnesium malate is bonded to malic acid: it supports ATP energy production and is positioned in fibromyalgia and daytime-energy products. Magnesium oxide is the cheap inorganic form: it has poor absorption (around 4 percent) and dominant laxative activity, which is why mass-market multivitamins often list "magnesium" but the elemental amount delivered is much lower. We stock all four, and for BOFU sleep-and-anxiety positioning we lead with bisglycinate.
How much elemental magnesium does 200mg of bisglycinate actually deliver?
Magnesium bisglycinate is about 14 to 18 percent elemental magnesium by weight (the rest is the two glycine amino acid molecules). So 200mg of bisglycinate delivers about 28 to 36mg of elemental magnesium per gummy. We recommend transparent labeling that shows BOTH the bisglycinate weight (the form claim) AND the elemental magnesium amount (the bioavailable yield). For the published-trial sleep and anxiety doses (around 400mg elemental magnesium), brands typically use either 400mg-per-capsule SKUs or stack 2 to 3 of the 200mg gummies. We help you model this against your shelf-price target before production.
Is "magnesium glycinate" always real bisglycinate?
No. A meaningful share of products labeled "magnesium glycinate" in the mass market are actually blends of magnesium oxide plus free glycine amino acid, sold under the cheaper magnesium-oxide cost structure. The chelation makes a real difference in bioavailability and GI tolerance. We HPLC-verify the chelation on every batch and name the bisglycinate form on the COA. If your positioning leans on the bisglycinate distinction, we recommend transparent on-pack language ("magnesium bisglycinate chelate") and a COA-on-request program for educated buyers.
What format ships at 500-unit MOQ?
Gummies. The 200mg-per-gummy pectin format ships at 500-unit MOQ per SKU with custom labeling, the BOFU sweet spot for testing the market without inventory risk. Capsules (400mg-per-cap clinical dose) ship at 3,000-unit MOQ. Stick packs (150-200mg single-serve) ship at 3,000-unit MOQ. Bottles and pouches only on gummies (no individual sachet wraps, no shrink wrap). First orders should allow 8 to 10 weeks from inquiry to finished goods (sampling, artwork, regulatory review, production, shipping).
Can you formulate the Huberman sleep stack?
Yes. The gold-standard non-melatonin sleep stack architecture (PharmaGABA 100mg + L-theanine 200mg + magnesium glycinate 400mg + apigenin 50mg) is one of our most-requested formulations. We ship it as a single multi-active capsule, a multi-active gummy (lower per-active doses, taste-driven), or as a 3-SKU stack-pack collection where each SKU is a single active and consumers stack to their preference. Custom variations (adding glycine 3g for sleep onset, tart cherry juice powder for melatonin precursor, or ashwagandha KSM-66 for cortisol modulation) add 4 to 6 weeks from approved formula.
Lead time, sample cost, and label design pricing?
Stock formulations ship in 3 to 4 weeks with approved artwork. Custom formulations require 4 to 6 weeks from approved formula. Samples cost $150 for one SKU (UPS shipping included to most countries) with $20 per additional SKU on the same order, credited against your first production order. Label design is $250 for up to 3 labels, then $120 per additional 3, or you can send your own print-ready files. First orders should allow 8 to 10 weeks total from inquiry to finished goods.

Private Label Magnesium Bisglycinate Manufacturing
Magnesium glycinate (technically magnesium bisglycinate, the chelated form where elemental magnesium is bonded to two glycine amino acids) is the single fastest-growing magnesium form on the modern supplement shelf. Search demand for "magnesium glycinate" has grown approximately +110% year-over-year per industry keyword research (Glimpse, 2026), driven by three converging trends: viral "sleepy girl mocktail" TikTok positioning, mainstream awareness that elemental magnesium oxide (the cheap mass-market form) is poorly absorbed and laxative-dominant, and the Huberman protocol elevation of 400mg bisglycinate as a non-melatonin sleep stack anchor. Brands that lead with the bisglycinate distinction (and the 200mg-per-gummy dose anchor) capture the educated buyer who has explicitly ruled out cheaper magnesium forms.
Our magnesium glycinate manufacturing program ships in three dose-anchored formats. The headline format is 200mg-per-gummy bisglycinate (pectin-based, low-sugar, 500-unit MOQ, the format that wins shelf attention against magnesium-oxide gummies in the mass-market multivitamin lane). The clinical format is 400mg-per-capsule bisglycinate (the published-trial sleep and anxiety dose; suits 60-count and 90-count bottles for the Huberman-protocol calm-and-sleep positioning). The stick-pack format is 150-200mg per serve (single-serve magnesium powders that ride the bedtime-drink ritual, mix into the sleepy-girl-mocktail trend, or pair with tart cherry juice and l-theanine for ready-to-mix sleep beverages). Pricing across the magnesium-glycinate category runs $0.95 to $2.80 per unit depending on dose, format, and order tier.
Whether you are launching a standalone magnesium-glycinate SKU, building a non-melatonin sleep stack around the gold-standard PharmaGABA + L-theanine + magnesium glycinate + apigenin architecture, or anchoring a calm-and-anxiety product around the bisglycinate-vs-oxide differentiator, our private label partnership delivers the formulation depth, regulatory review, and production flexibility to bring your concept to market in 4 to 6 weeks. Every batch is produced in our FDA-registered, cGMP-certified facility under 21 CFR Part 111, with third-party identity testing on the chelated magnesium active, elemental magnesium potency verification, heavy-metal screening, and stability validation across your chosen format.
Our Manufacturing Process
From initial concept to finished product, every step is managed under one roof with dedicated quality oversight and transparent communication.
Bisglycinate vs Citrate vs Malate: Form Selection
Our formulators help you pick the right magnesium form for your target positioning. Bisglycinate (glycinate): sleep, anxiety, calm, the most-bioavailable chelated form, gentle on the stomach. Citrate: constipation relief, the gut-motility form (note: this is a distinct positioning lane). Malate: ATP energy and fibromyalgia, the daytime-energy form. We stock all three with full COAs, and most BOFU brands lead with bisglycinate. Cost per elemental-magnesium milligram modeled before production.
Dose-Anchored Formula Design (200mg / 400mg / 150-200mg stick)
The 200mg-per-gummy anchor wins against magnesium-oxide gummies in the mass-market lane (gummy MOQ 500). The 400mg-per-capsule anchor matches the published-trial sleep and anxiety dose for clinical-grade positioning (capsule MOQ 3,000). The 150-200mg single-serve stick rides the bedtime-drink trend (stick pack MOQ 3,000). We model cost per dose across each before production, and we recommend transparent elemental-magnesium labeling (chelated bisglycinate weighs about 5x its elemental yield).
21 CFR Part 111 Production with Bisglycinate Identity Testing
Manufactured in our FDA-registered, cGMP-certified facility under 21 CFR Part 111. Every batch undergoes identity testing on the chelated bisglycinate active (HPLC verification that the magnesium is bonded to two glycines, not blended), elemental magnesium potency verification, heavy-metal screening (lead, arsenic, cadmium, mercury), microbiological analysis, and stability validation. The identity test matters: a meaningful share of "magnesium glycinate" supplements on Amazon are actually buffered blends of magnesium oxide and glycine, not true bisglycinate. We name what we ship.
Packaging, FTC Claims Review, and Sleep-Mocktail Positioning
Packaged in bottles or pouches (no individual sachets or shrink-wrap) with full label compliance review. Our regulatory team reviews every structure-function claim around sleep, calm, and anxiety positioning to keep your brand on the right side of FDA and FTC standards. The sleepy-girl-mocktail and bedtime-drink positioning lanes are claim-sensitive: we help you map the trend energy onto compliant copy without triggering enforcement. Label design $250 for up to 3 labels, $120 per additional 3, or send your own files.
Key Benefits for Your Brand
Every aspect of our magnesium glycinate manufacturing is designed to accelerate your time-to-market while maintaining uncompromising quality standards.
200mg Bisglycinate Per Gummy, 500-Unit MOQ
The bank-anchored format: 200mg of true magnesium bisglycinate per pectin gummy, low-sugar, in bottles or pouches at 500-unit MOQ. The format the mass-market multivitamin-gummy aisle is shifting toward as consumers reject magnesium-oxide blends. Pectin-based (vegan-friendly), naturally flavored, optionally sugar-free.
True Bisglycinate, Not Buffered Magnesium-Oxide Blends
A meaningful share of "magnesium glycinate" products on Amazon are actually blends of magnesium oxide plus free glycine (cheaper, less bioavailable, but cleared to label as "magnesium glycinate"). We HPLC-verify the chelation on every batch and name what we ship. This is the trust premium educated calm-and-sleep buyers reward.
Stomach-Gentle Form for the Sleep and Anxiety Lane
Bisglycinate is the magnesium form with the lowest documented gastrointestinal side-effect profile (no laxative effect at normal doses, unlike citrate or oxide). That is what makes it the right form for nightly sleep-onset positioning, where consumers take the supplement before bed and need no morning GI consequences. Suits anxiety, sleep, and PMS-calm positioning.
Sleep-Stack Compatibility (Huberman Protocol Architecture)
400mg of magnesium bisglycinate is the published-trial dose anchor in the gold-standard non-melatonin sleep stack (PharmaGABA 100mg + L-theanine 200mg + magnesium glycinate 400mg + apigenin 50mg). We formulate the full stack in capsule, gummy, and stick-pack formats as a single SKU or split-SKU collection. Common stack partners: glycine 3g (sleep onset), tart cherry (melatonin-precursor), GABA, L-theanine.
FDA-Registered cGMP Production with Per-Batch COA
Produced under 21 CFR Part 111 with ISO 17025 third-party batch testing: identity verification on the bisglycinate chelation, elemental magnesium potency, heavy-metal panel, microbiological screen, and stability. COA per batch ships with every order. The credentials calm-and-sleep retailers (Whole Foods, Sprouts, Erewhon, Amazon Premium Beauty) increasingly require before accepting a private label brand onto the shelf.
