Micro Ingredients Review 2026: Is It Worth Buying?

Last updated: September 25, 2026 · Originally published September 11, 2026 · Published by Eternal Elixir

Edited by Elaine Fletcher, Researcher

Quick answer: This Micro Ingredients review for 2026 finds a real California supplement company that sells hundreds of low-priced powders and capsules through its own store, Amazon, Walmart and TikTok Shop. It can be worth buying for bulk basics, as long as you read the supplement facts panel first. On the longevity shelf, the big number on the front is often a blend total. The NMN Complex says 1,000 mg per serving, but 500 mg of that is NMN and 450 mg is a blend with no individual amounts. Our pick for NMN is Eternal Elixir NMN 500mg: 500 mg of NMN in each capsule and 90 capsules for $49.99, which works out to about $1.11 per gram of NMN against $1.33 for the 120-capsule NMN Complex.

Eternal Elixir makes NMN 500mg and Trans-Resveratrol 600mg, the two products we compare with Micro Ingredients below, and NMN 500mg is our pick. We compete with Micro Ingredients, so read this as a competitor’s review. We did not buy or lab-test its products. Every Micro Ingredients figure comes from its product pages, FAQ page, return policy and retailer listings, or from public court and Proposition 65 records, all read on September 25, 2026. Here is how we write and review content.

Micro Ingredients review 2026: who makes it and where it is made

Micro Ingredients is a trade name of DPL Trading, Inc., a company based in Montclair, California. DPL Trading filed the MicroIngredients trademark in September 2015, and it was registered in November 2016. A September 2025 Proposition 65 notice is addressed to “DPL Trading, Inc. dba Micro Ingredients” at a Montclair street address, and it also names a Washington company, Bayland Health Products LLC, as doing business as Micro Ingredients. The brand’s own FAQ says the company is located in Montclair.

According to that FAQ, all Micro Ingredients products are manufactured in the US, while the ingredients are sourced “from regions all over the world.” The company says it can tell you the country of origin for your pack if you send it the lot number printed on the back. It also describes itself as a raw material supplier, and the catalog shows it: the public product feed on its store listed 484 products when we checked, from collagen and fish oil to fruit powders and culinary goods.

The FAQ names four places where it sells: its own store, Amazon, Walmart and TikTok Shop. It tells US buyers to stick to its verified channels if they want a genuine product. Its own store ships free on orders over $59. Return requests are accepted within 30 days of delivery for unused items in their original packaging, but the buyer pays return shipping, a $10 handling fee is taken off each return request, and sale items can’t be returned. That last rule matters, because much of the store, including the NMN Complex, was marked as on sale when we looked. The refund promise also covers only US orders placed on its own website, so marketplace orders follow the marketplace’s rules.

Is Micro Ingredients reputable? What the public record shows

Testing

ConsumerLab, a subscription service that buys supplements and tests them, lists four Micro Ingredients products as tested. It says three were approved for quality and one of those is a Top Pick. The public page mentions categories where the brand appears, such as vitamin C, D-mannose and greens, but the product-level results are for members only. It does not say which four products were tested, so it tells you nothing about the NMN or resveratrol capsules.

The brand’s product pages say its supplements are third-party lab tested for purity, safety and potency, and its FAQ says the testing covers heavy metals and micro-organisms and that it hires outside labs to check raw materials. We did not find a certificate of analysis for a specific lot on the product pages we opened. If testing decides it for you, ask for the certificate that matches the lot number on your bottle. That advice holds for every brand, ours included.

Customer service

The brand has not claimed its Trustpilot profile, and one-star reviews dominate it. The recent complaints we read were about orders stuck in fulfillment for weeks and email-only support with slow replies, plus at least one report of a bottle that arrived already expired. Its product listings on retail sites read differently: its Liver+ Advanced listing on iHerb, for example, is rated well by buyers. Most of the complaints concern the brand’s own store and support, though a few question product quality. Buying through a marketplace puts shipping and returns under that marketplace’s policies, which sidesteps most of what the negative reviews describe.

Legal notices and the lawsuit

Two kinds of legal record come up when you search the brand. None of them involves its NMN, NAD+ or resveratrol capsules.

• Proposition 65 notices. California’s Proposition 65 lets private groups send a 60-day notice when they allege that a product exposes buyers to a listed chemical without a warning. In a 2023 settlement with Clean Products Advocates over a kelp powder alleged to contain lead, DPL Trading agreed to pay a $500 civil penalty and $8,250 in legal fees and to warn buyers, reformulate or stop selling the product in California. A September 2024 notice alleged lead in its Ceylon cinnamon and freeze-dried spinach powders. A September 2025 notice from Environmental Research Center alleged lead in its wheat grass, ginkgo and ginger powders and PFOA in its pea protein powder, and a related complaint was filed in Alameda County Superior Court in December 2025. These are allegations. The records we read contain no court finding against the company.
• The class action. In September 2025, a buyer filed a proposed class action, Willis-Albrigo v. DPL Trading, Inc., in federal court in California. It alleges that the “10g protein” claim on the front of Micro Ingredients Pure Peanut Powder misleads buyers because the label does not show how much of that protein the body can use. The latest docket entries we could see, from November 2025, were a protective order and an extension of time to answer the complaint. We found no settlement or ruling on the public docket.

Decoding the NMN Complex label: 1,000 mg per serving, 500 mg of NMN

The NMN Complex is the brand’s main longevity product. A two-capsule serving lists 1,000 mg in total, made up of three parts:

• 500 mg of beta-nicotinamide mononucleotide (NMN)
• a 450 mg blend of resveratrol (98% trans-resveratrol), grape seed extract, CoQ10, reduced glutathione, TMG, quercetin, astaxanthin and apigenin
• 50 mg of vitamin C as ascorbyl palmitate

To its credit, the product page spells this out, and its own FAQ repeats that each serving holds 500 mg of NMN. The blend is the weak spot. Eight ingredients share 450 mg, and the label gives no amount for any single one of them. You can’t check the resveratrol or TMG in it against a study dose, or against what a single-ingredient bottle gives you.

The page suggests two capsules a day with a meal, or one a day to start if you are new to NMN. It comes in a 120-capsule bottle (60 servings) and a 60-capsule bottle (30 servings). The brand also sells a plain NMN product with 200 mg per two-capsule serving, 120 capsules for $32.95.

Its other NAD+ products take a different route. The NAD+ Supplement 500mg with Resveratrol gives 500 mg of NAD+ and 50 mg of resveratrol per three-capsule serving, at $39.95 for 240 capsules. The Liposomal NAD+ Ultimate lists a 1,000 mg “combined serving” of ten ingredients without saying how much of it is NAD+. Both supply NAD+ itself rather than NMN, so the NMN trials below don’t tell you what they do.

Micro Ingredients NMN vs Eternal Elixir NMN 500mg: cost per gram

Bottle prices hide the real difference, because serving sizes and doses vary. The table counts only NMN, using each label’s stated amount and the one-time price on each brand’s US store as of Sep 2026. Micro Ingredients was running a storewide fall sale, so its prices may go up later.

Add NMN 500mg to cart · $49.99

Ours gives the most NMN per dollar in this table, and every capsule carries 500 mg of NMN with nothing else competing for the space. The 120-capsule NMN Complex comes close. At $0.67 a serving it is a fair price for 500 mg of NMN, and the blend comes with it. Whether the blend is worth having is hard to judge when none of its eight ingredients has a stated amount.

The cheapest bottle is the most expensive NMN. The NMN 200mg product costs more than twice as much per gram as ours, and you would need three of its servings, six capsules, to reach 600 mg. If you are weighing other brands too, our ranking of the best NMN supplements by disclosed dose runs the same arithmetic across the US market.

What the NMN research used, and how the labels compare

The human NMN trials are small and short. Most of them measure blood NAD+ and walking tests rather than long-term health, and two recent ones set the dose range most buyers aim for.

In a 60-day randomized, placebo-controlled trial in GeroScience (Yi and colleagues, 2023), 80 healthy middle-aged adults took a placebo or 300 mg, 600 mg or 900 mg of NMN once a day. Blood NAD+ rose in all three NMN groups by day 30 and was highest at 600 mg and 900 mg. Six-minute walking distance improved more in every NMN group than with placebo. Three of the authors were employees of ingredient companies, Abinopharm and ABA Chemicals.

In a 12-week trial in older adults, published in the same journal (Morifuji and colleagues, 2024), 60 participants took 250 mg of NMN a day or a placebo. The main measure, a stepping test, showed no difference between the groups. Blood NAD+ rose and 4-meter walking time got shorter in the NMN group, but those were secondary measures. Three of the four authors work for Meiji Holdings.

Both brands’ 500 mg amounts sit inside the range these trials tested. Each of our capsules holds 500 mg, so follow the serving on the bottle’s label. The NMN Complex reaches 500 mg with its full two-capsule serving. Evidence level: small randomized human trials that measured blood NAD+ and walking tests over two to three months. NMN has not been shown to extend human lifespan, and we found no published trial of either brand’s own product. For how NMN compares with other NAD+ precursors, see our NMN versus nicotinamide riboside guide, our comparison of NAD+ supplements by disclosed dose and our look at higher-dose NMN routes.

Resveratrol and berberine: where Micro Ingredients wins on price

A review that only found points in our favor would not be much use, so here is where the numbers go the other way.

The Resveratrol Supplement 3,000mg is the brand’s other longevity staple. A three-capsule serving holds 1,000 mg of Japanese knotweed resveratrol standardized to 50% trans-resveratrol, which is 500 mg of trans-resveratrol, plus a 2,000 mg blend that includes NAD, berberine, quercetin and green tea. A 240-capsule bottle gives 80 servings for $24.99. It was sold out on the brand’s own store when we checked.

When it is in stock, the Micro Ingredients complex is the cheaper way to buy trans-resveratrol, at a little over half our cost per gram. The trade-off is a three-capsule serving of a 50% extract, with 2,000 mg of other ingredients whose amounts aren’t listed. Ours is one capsule per serving. If cost per gram is all that matters to you and it comes back in stock, theirs is the better buy for this one ingredient. Our resveratrol supplement comparison covers more options, and our NMN versus resveratrol guide explains how the two fit together.

One caution applies to every resveratrol product, ours included. In a small study in Drug Metabolism and Disposition (Walle and colleagues, 2004), six volunteers took a 25 mg oral dose of labeled resveratrol. At least 70% of it was absorbed, but only trace amounts of unchanged resveratrol showed up in the blood, because the gut and liver convert it quickly. A bigger number on the label does not guarantee more resveratrol in your blood. Evidence level: small human absorption studies, with no trial showing that a higher daily amount works better.

Add Trans-Resveratrol 600mg to cart · $59.99

Berberine follows the same pattern. Micro Ingredients’ Berberine 1000mg softgels give 1,000 mg of berberine HCl per four-softgel serving, and the 240-softgel bottle costs $29.95, about $0.50 per gram. Our Berberine HCl 500mg costs $49.99 for 90 one-capsule servings, which is $0.56 a serving and about $1.11 per gram. Theirs is cheaper per gram, and ours is one capsule per serving instead of four softgels. Berberine can interact with some medicines, so talk to your doctor before taking it if you use any prescription medication. Our berberine comparison pegged to disclosed milligrams covers other brands.

Micro Ingredients Liver+ Advanced: what the label shows

Liver+ Advanced, sold on the brand’s own store as Liver Advanced+, comes up often in searches about the brand. A two-capsule serving combines 20 ingredients, and the 240-capsule bottle gives 120 servings for $24.95 on the brand’s store or $28.99 on iHerb. The supplement facts panel on iHerb lists:

• 24 mg of choline, 30 mg of zinc (273% of the Daily Value) and 100 mcg of selenium
• a liver blend with stated amounts, led by milk thistle extract at 200 mg and astragalus and dandelion at 100 mg each
• an “advanced” blend of 550 mg holding NAC, NAD, alpha lipoic acid, glutathione, TUDCA, berberine HCl, schisandra, chicory and chanca piedra, with no individual amounts

Buyers on iHerb rate it well, and the complaints on Trustpilot are mostly about orders and support rather than this formula. We found no published trial of the product itself. Two label points are worth knowing before you buy. The TUDCA and berberine amounts sit inside the undisclosed 550 mg blend, so you can’t match them with any study dose. And 30 mg of zinc is a lot to add to a daily routine. The adult upper limit for zinc from food and supplements combined is 40 mg a day, so do not stack it with a zinc-containing multivitamin without checking the total, and talk to your doctor if you take other medicines.

The brand’s separate TUDCA 2,000mg product works the same way. Its three-capsule serving is a 2,000 mg blend of TUDCA, NAC, glutathione, milk thistle, dandelion, artichoke and taurine, with 80 servings for $34.95, and the product page text does not give the TUDCA amount on its own. Our TUDCA dosage and safety guide sets out what is known about the ingredient, and our TUDCA supplement comparison lists brands that state the amount.

Who Micro Ingredients suits, and who should buy elsewhere

It suits you if you want cheap bulk powders or basic single nutrients, like combination formulas, and don’t mind taking two to four capsules per serving. On trans-resveratrol and berberine it costs less per gram than ours, when those products are in stock.

Buy elsewhere if you want to know exactly how much of each active you take, because the longevity complexes lean on blends without amounts. The same goes if reliable customer service matters to you, going by the reviews of its own store, or if you want the option to return a sale item. For NMN, Eternal Elixir NMN 500mg gives 500 mg in each capsule with no blend, costs less per gram of NMN than any of the three NMN bottles on Micro Ingredients’ own store, and comes with our 30-day money-back guarantee.

Micro Ingredients review: frequently asked questions

Is Micro Ingredients a reputable brand?

It is a real, established company whose trademark dates to 2015, and ConsumerLab says three of the four Micro Ingredients products it tested were approved for quality. Its weak points are customer service at its own store, where Trustpilot reviews are mostly one star, and labels that rely on blends without stated amounts. It has also received several Proposition 65 notices over lead in some powders and faces a proposed class action over a protein claim on its peanut powder.

Is Micro Ingredients a Chinese company?

It is a US company. Micro Ingredients is a trade name of DPL Trading, Inc., based in Montclair, California, which owns the MicroIngredients trademark. Its FAQ says all its products are manufactured in the US and that ingredients are sourced from many countries. It offers to tell you the country of origin for your pack if you send the lot number.

What was the outcome of the lawsuit against Micro Ingredients?

There is no outcome yet that we could find. The proposed class action, Willis-Albrigo v. DPL Trading, Inc., was filed in federal court in California in September 2025 over the “10g protein” claim on its peanut powder. The latest public docket entries we saw date from November 2025, with no ruling or settlement. A separate Proposition 65 matter over a kelp powder was settled in 2023, with a $500 civil penalty and $8,250 in legal fees.

What are people saying about Micro Ingredients Liver+ Advanced capsules?

Buyers on iHerb rate it well, and the Trustpilot complaints about the brand focus on orders and support rather than this formula. The label combines 20 ingredients, including 200 mg of milk thistle extract, but TUDCA, NAC, glutathione and berberine share an undisclosed 550 mg blend. Each serving also gives 30 mg of zinc, so check your total zinc intake before adding it and talk to your doctor if you take other medicines.

Are Micro Ingredients supplements third-party tested?

The company says they are, for purity, safety and potency, and its FAQ says the tests cover heavy metals and micro-organisms. We did not find lot-specific certificates of analysis on the product pages we opened, so ask for the certificate that matches your lot number if testing matters to you.

Where is Micro Ingredients made?

The company says all its products are manufactured in the US, and its offices are in Montclair, California. Ingredients come from many countries, and the lot number on your pack is how the company traces the origin of your specific purchase.

How much NMN is in Micro Ingredients NMN Complex?

500 mg per two-capsule serving. The 1,000 mg on the front of the bottle also counts a 450 mg blend of eight ingredients and 50 mg of vitamin C. At $39.95 for 120 capsules, that works out to about $1.33 per gram of NMN.

What is the best alternative to Micro Ingredients NMN?

Our pick is Eternal Elixir NMN 500mg, which we make. Each capsule holds 500 mg of NMN with no blend, and a 90-capsule bottle costs $49.99, or about $1.11 per gram of NMN against $1.33 for the 120-capsule NMN Complex and $2.75 for Micro Ingredients NMN 200mg. It does not contain the NMN Complex’s resveratrol, TMG or CoQ10, so choose the complex if you want those in one capsule.

Our verdict on Micro Ingredients

Micro Ingredients is a legitimate California bulk-supplement company with a huge catalog, low prices and a record of legal notices that concern its powders rather than its capsules. Its store service draws heavy criticism, and its longevity products lean on blends without stated amounts. It is the cheaper buy for trans-resveratrol and berberine when those are in stock. For NMN, the numbers favor a disclosed single-ingredient capsule: our NMN 500mg gives 500 mg in every capsule and costs less per gram of NMN than any of the three NMN bottles on Micro Ingredients’ store.
