DaVinci Laboratories Supplements: Which to Buy for Your Goal

DaVinci Laboratories has been on supplement shelves since 1973, and it turns up in a lot of the same searches as the other practitioner-grade brands, usually with one question attached: is it actually worth the money? This guide answers that head on, then does what the manufacturer's own pages do not. It sorts the line by your goal, names the products worth a look in each group, and grades the evidence behind the well-known ingredients, including where that evidence is weak, mixed, or points the other way.

Is DaVinci Laboratories a Brand You Can Trust?

Short answer: yes, and the reasons are specific enough that you can check them yourself.

DaVinci Laboratories has been making supplements since 1973 and is now part of FoodScience LLC, a family-owned company based in Williston, Vermont. Its facility is an FDA-registered food facility and is GMP certified to SQF food safety and NSF GMP 455-2 standards. Every manufactured lot is assayed to confirm it meets specification.

That combination of history, a registered facility, two third-party GMP standards, and lot-level testing is what "practitioner-grade" is supposed to mean. Agape Nutrition carries 165 active DaVinci Laboratories products, one of the deeper brand relationships in our catalog.

What none of that tells you is whether a specific bottle fits your goal. That is what the rest of this page does, including the parts the brand's own site leaves out.

Four checkpoints of DaVinci Labs supplements: established 1973, registered facility, GMP certified, lot assayed.
Four checkpoints a practitioner-grade brand should be able to name: how long it has formulated, a registered facility, a third-party GMP standard, and lot-level testing.

What DaVinci's Credentials Actually Mean

Those credentials read like a wall of acronyms. Here is what each one means, and what it does not prove.

  1. Founded in 1973 and part of FoodScience LLC. Longevity is a weak signal on its own, but it does mean the company has survived five decades of FDA rule changes.
  2. FDA-registered food facility. Registration means the plant is known to the FDA and subject to inspection. It is not FDA approval, and no supplement is FDA-approved.
  3. GMP certified to SQF food safety and NSF GMP 455-2. GMP stands for good manufacturing practices. SQF and NSF 455-2 are third-party schemes, so an outside auditor certified the plant.
  4. Lot-level assay. Every batch is tested against specification before release. This is the credential that touches you directly: a certification describes a building, an assay describes your bottle.

A certification describes the building. An assay describes your bottle. When you are deciding what to buy, the assay wins.

One gap worth naming: DaVinci does not claim USP certification anywhere, so do not assume it holds one. USP is a separate program.

Those four checkpoints are what any practitioner-grade brand should name. If a brand cannot answer all four, the premium is not buying what you think.

The Honest Quality Record

Most brand guides skip this section. Skipping it would make everything above less believable.

ConsumerLab's page on DaVinci Laboratories documents two recalls, and both were undeclared-allergen labeling events:

  • 2024: one lot of Amyloid Complete capsules, roughly 72 bottles, recalled for undeclared crustacean ingredients.
  • 2019: 256 bottles of Dim Plex recalled for undeclared fish proteins.

Neither event was a potency failure or a contamination failure. No one was reported harmed by a wrong dose or a bad batch. The problem was an allergen present in the product but not declared on the label. That matters greatly if you carry a shellfish or fish allergy, and very little if you do not.

The honest reading is not that this brand is unsafe. It is that an allergen statement is only as reliable as the lot it was printed for. Check the bottle you own:

  1. Read the allergen line, not just the supplement facts panel.
  2. Keep the lot number, and match it against any recall notice you find.
  3. If you have a serious food allergy, buy from a retailer that can trace the lot.

A recall for an undeclared allergen is a labeling problem. A recall for potency or contamination is a manufacturing problem. Knowing the difference is most of what label literacy means.

DaVinci Laboratories product families grouped by goal, from methylation and B vitamins to bone, joint and skin.
The DaVinci line organized by what you are trying to do, not by what the bottle is called.

The Line, Organized by Goal

With 165 products on the shelf, browsing is the slowest way to shop this brand. Name your goal, then look at the products that serve it. Most people need one or two groups, not ten.

Methylation and B Vitamins

Look at Methyl Benefits, 5-MTHF 1 mg, 5-MTHF/B12 MC2000, Chewable B12-MC, and Active Folate B12 Chewable.

This is the best-evidenced group in the line. 5-MTHF, the reduced form of folate, absorbs well even when digestive pH is altered and is unaffected by the defects that limit synthetic folic acid [1] [2]. Riboflavin is the quiet standout: in people with the MTHFR 677C>T variant it lowered homocysteine [3] and supported healthy blood pressure [4] [5]. High-dose synthetic folic acid is the one to be careful with: a meta-analysis of controlled studies [7] found a small increase in overall cancer incidence that sat right on the edge of significance, and a separate trial in people with a history of colorectal adenomas found more advanced lesions [6]. Our detox and methylation pillar goes deeper.

Energy and Mitochondria

Mitochondria are where cells make ATP. Look at Ubiquinol 100 mg, CoQsol 100 mg, Mito-Fuel, Alpha Lipoic Acid 300, and Iron Bis-Glycinate.

CoQ10 is the anchor, and its evidence is contested: some pooled analyses report less muscle pain [49] [50], while an earlier systematic review [8] and meta-analysis [9] found insufficient or no benefit, and the largest trial in confirmed cases found none [10]. Alpha-lipoic acid carries three multicenter trials at 600 mg [11] [12] [13], all in people with diabetic peripheral neuropathy, a condition named by the research and not a product claim, and the results are mixed: the three-week trial reduced symptoms [11], while the seven-month and two-year trials did not separate from placebo on their symptom endpoints [12] [13]. Ferrous bisglycinate at 25 mg matched ferrous sulfate at 50 mg [14].

Stress, Mood and Sleep

Look at L-Theanine, Cortisol Benefits, Adrenal Benefits 60 ct, Relora with Bacopa, and Liposomal Melatonin Spray.

L-theanine has the cleanest human data here: it reduced psychological and physiological stress responses [15], and a randomized trial in healthy adults found effects on stress-related symptoms and cognition [16]. The adrenal blends rest on traditional use and smaller trials, and melatonin is best used at the lowest effective dose for a short period, with a prescriber's input if you take other medication. Our brain and memory pillar covers more.

Heart and Circulation

Look at Cardio Benefits, BP Elite, Nattokinase Plus, Omega 3 HP-D, and Pycnogenol-50.

Nattokinase has a specific, modest human finding behind it: oral nattokinase produced an early, mild increase in plasma fibrinolytic activity [17]. Pycnogenol has a longer review record [18], with endothelium-dependent vascular effects shown in laboratory work [19]. 5-MTHF appears here too, studied for endothelial function in familial hypercholesterolemia [20], a study population named by the research. Our heart and circulation pillar covers the categories around it.

Blood Sugar and Metabolism

Look at Berberine Force, Carb-Down with Phase 2, Adipo-Leptin Benefits, Metabolic Multi, and Tonalin-CLA.

Berberine is the strongest ingredient here by a wide margin. It activates AMPK in laboratory and animal work [21] and has lowered blood glucose in people with type 2 diabetes through increased insulin receptor expression [22]; the gut-microbiota shifts have been shown in animals [23]. Those are research outcomes in a specific population, not a promise about your numbers. Everything else in this group is softer. Our weight and metabolism pillar explains why these markers resist single fixes.

Digestion and Gut

Look at Mega Probiotic ND 50, Mega Probiotic ND 120, Digenzyme, GI Benefits, and Arabinogalactan Powder.

The evidence here is about delivery, not a magic strain. Probiotic bacteria survive gastric transit differently by strain, and most do not survive it well: in simulated gastric transit 14 of 15 isolates lost more than 90 percent of their viability, while adding milk proteins improved tolerance [24]. Survival rates for selected strains are estimated at 20 to 40 percent, limited by gastric acid and bile salts [25]. Encapsulation is one of the formulation levers [26], which is why the same CFU count on two labels does not mean the same thing. ND means non-dairy, and larch arabinogalactan has a review of mechanistic and clinical work behind it [27], though that review is about immune support rather than digestion. Our digestion and gut health pillar covers the levers that come first.

Liver and Detox

Look at Detox Benefits, Hepaticlear, Milk Thistle, Multiphase Detox, and N-Acetyl Cysteine 500 mg.

Milk thistle has the best-known record: silymarin has a narrative review of its supportive role in liver health [28] and a meta-analytic literature researchers still debate [29]. NAC supports glutathione instead. Be skeptical of anything promising to flush or cleanse a specific organ. The honest framing is antioxidant support and support for the body's own detox pathways.

Immune Support

Look at Immuno-DMG, Immuno-DMG Chewable, Aller-DMG, Gluconic DMG 250 mg, and Zinc Lozenge.

Zinc is the ingredient with real trial support: a systematic review and meta-analysis found oral zinc shortened cold symptom duration in adults, a condition named by the research and not a product claim, with no significant effect in children and high heterogeneity between trials [30], and an earlier randomized trial of zinc acetate showed the same direction [31]. DMG is the honest caveat. The human trial record is thin and null: a one-year pilot RCT in progressive multiple sclerosis (n=30) found no effect on disability, fatigue, cognition, or gait [32], and much of the remaining work is in animals or laboratory models. That leaves mechanism and long clinical use, not human outcome data.

Bone and Joint

Look at Vitamin K2 Plus, D3/K2 Liquid, Cal-MAG Citrate Powder, Tri-MAG 300, and Curcumin C3 Complex.

Vitamin K2 is the one to know: menaquinone intake was associated with lower coronary heart disease mortality in the Rotterdam Study, an observational cohort [33], and menatetrenone has been studied for maintaining lumbar bone mineral density [34]. With magnesium, form matters more than milligram count. Citrate delivered more than oxide in a direct comparison [35], and diglycinate absorbed better in those absorbing worst [36]. Curcumin absorbs poorly alone [37], which is why piperine changes the picture [38]. Our bone, joint, and pain pillar covers the wider shelf.

Skin, Hair and Eyes

Look at Hair Effects, Healthy Eyes, Natures Collagen, Hyaluronic Acid, and Biotin.

Collagen peptides have the better oral evidence for skin, and it is not close: controlled work has measured skin elasticity and wrinkle outcomes [39] [40]. Oral hyaluronic acid is the weaker bet here, and biotin's data is strongest in people who are deficient rather than in general use.

Evidence ladder for practitioner-grade supplements: strong human evidence, mixed or contested, and thin or negative.
The evidence is not evenly spread across the line. Berberine, L-theanine and magnesium citrate sit at the top; DMG, resveratrol and beta-carotene sit at the bottom.

Which Ingredients Have Real Evidence, and Which Do Not

This section is why you can trust the rest of the page. A guide that never says what is shaky is a sales pitch with citations.

Strong human evidence

  • Berberine for blood glucose in people with type 2 diabetes [22], with supporting laboratory and animal work on AMPK and gut microbiota [21] [23].
  • Riboflavin for homocysteine [3] and blood pressure support [4] [5] in people with the MTHFR 677C>T variant.
  • L-theanine for stress response [15] [16].
  • Zinc for cold symptom duration [30] [31], a condition named by the research and not a product claim.
  • Vitamin K2 for bone density maintenance and cardiovascular association [33] [34].
  • Collagen peptides for skin elasticity and wrinkle measures [39] [40].

Mixed or contested

  • CoQ10 for statin-associated muscle symptoms. Some pooled analyses report less muscle pain [49] [50]; others found insufficient or no benefit [8] [9], and the largest trial in confirmed cases found none [10]. That is a prescriber conversation, not a self-diagnosis.
  • Probiotics. Outcomes depend on the strain and on whether the capsule survives the stomach [24] [25] [26]. A generic claim is not a finding.
  • Silymarin. Long used and widely reviewed [28], still debated in the pooled literature [29].
  • Betaine HCl. Not a DaVinci product, though Agape carries it from other brands. Human work is small and mechanistic, on stomach reacidification in volunteers with medication-induced low stomach acid [46] [47]. Not for self-prescribing alongside acid-suppressing medication.

Thin, negative, or worth knowing before you buy

  • DMG. A thin, null human trial record [32], with much of the remaining work in animals and laboratory models.
  • Saw palmetto. The large trial in the New England Journal of Medicine found no benefit over placebo in men with benign prostatic hyperplasia [41]. Saw Palmetto 90 Capsules is in this line, and that is the study to know first.
  • Beta-carotene in supplement form. In the ATBC trial, male smokers taking beta-carotene supplements had increased lung cancer incidence [42], and CARET found the same direction with a beta-carotene plus vitamin A combination in a similar high-risk population [43]. That finding is scoped to those study populations and is not a general statement about everyone who takes a beta-carotene capsule. This line includes a Beta Carotene softgel, so if you smoke or had asbestos exposure, it is worth taking seriously.
  • Resveratrol. Oral resveratrol absorbs well but has very low bioavailability in humans [44], and a later review of human bioavailability agreed [45]. Resveratrol-50 is sold here, and a capsule should not be expected to deliver resveratrol outcomes.
  • Monolaurin. The antimicrobial work is in-vitro only [48], with no substantive human trial data.
  • Oral hyaluronic acid. Thin evidence, and collagen has the better oral data [39] [40]. Hyaluronic Acid 60 Capsules is the product.
  • Telomerase and Telomere Benefits. The human telomere data for supplements is thin, and it does not buy you anything you can measure. A pooled analysis of eight randomized trials of a telomerase-activating supplement [51] reported a modest telomere-length signal, but it came with no improvement in frailty or inflammation, and the meta-analysis itself found that industry-funded trials reported larger effects than independent ones. Telomere Benefits is best understood as a multi-nutrient antioxidant formula, and that is the only claim it should carry.

Mechanism is cheap and outcomes are expensive. An ingredient can have a beautiful pathway and no human result. Ask which one you are being sold.

Three-step label checklist for DaVinci Labs supplements: allergen statement, serving and form, and lot testing.
Three checks before you buy: the allergen statement, the serving size and form, and lot traceability.

How to Read a DaVinci Label Before You Buy

You now know more than the average buyer. Here is the filter to apply in the aisle.

The three checks on the bottle

  1. The allergen statement. Read it, not just the supplement facts. This is the exact line that failed twice in the recall record above.
  2. The serving size and the form. 500 mg of magnesium oxide and 500 mg of magnesium citrate are not the same product [35] [36], and "per serving" can mean three capsules.
  3. Testing and lot traceability. Lot-level assay is claimed here, and the real question for any brand is whether you can get documentation for your lot. A certificate is lot-specific, so a generic testing badge proves nothing.

Spotting a product that is doing real work

  • It names a form, not just a nutrient: citrate, glycinate, methylfolate, menaquinone, bisglycinate.
  • It states an amount per serving instead of hiding behind a proprietary blend.
  • It has a stated dose you can match to a study, not a number chosen to look impressive.
  • It has one or two actives you can evaluate, not fifteen at trace amounts.

If a label cannot survive those four questions, the formula is decoration. If you want help narrowing the line to your goal, the Agape team can point you to two or three products instead of the whole shelf.

The Bottom Line

DaVinci Laboratories is a real practitioner-grade brand with checkable credentials: founded in 1973, part of FoodScience LLC in Vermont, an FDA-registered facility, GMP certified to SQF and NSF GMP 455-2, and lot-level assay on every batch. It also has a recall history, and both events were undeclared-allergen labeling problems, not potency or contamination failures.

Buy selectively rather than broadly. Methylated B vitamins, berberine, L-theanine, zinc lozenges, vitamin K2, magnesium citrate or glycinate, and collagen peptides are where evidence is strongest. DMG, saw palmetto, oral hyaluronic acid, and telomere products are where it is weakest.

Match the product to your goal, read the allergen line, and add one thing at a time.

Frequently Asked Questions

Is DaVinci Labs a reputable brand?

Yes. It has been formulating since 1973 and is part of FoodScience LLC, a family-owned Vermont company. The facility is FDA-registered and GMP certified to SQF food safety and NSF GMP 455-2, and every lot is assayed against specification. It does not claim USP certification, so do not assume one.

Why is DaVinci more expensive than the drugstore vitamin aisle?

The money goes into form choices, a hypoallergenic formulation posture, and lot-level testing rather than volume. If lowest cost per milligram is the goal, a mass-market label wins on price. If form is why you buy supplements, that difference is the product.

Which DaVinci products are actually worth buying?

A small group carries the strongest evidence: the methylated B and folate products, berberine, L-theanine, zinc lozenges, vitamin K2, magnesium in citrate or glycinate form, and collagen peptides. The rest of the line is not worthless, it is less proven per dollar, and the Agape team can help you narrow it down.

What happened with the DaVinci recalls?

Two undeclared-allergen recalls: one lot of Amyloid Complete in 2024 for undeclared crustacean ingredients, and 256 bottles of Dim Plex in 2019 for undeclared fish proteins. Both were labeling events, not potency or contamination failures. Read the allergen line and keep the lot number.

Is DaVinci Laboratories third-party tested?

The brand states that every lot is assayed to specification and that the facility is certified to SQF and NSF GMP 455-2, both third-party schemes. What no retailer can publish for you is a certificate, because one is lot-specific. Ask for yours.

Can I take DaVinci supplements with prescription medication?

Sometimes, but that belongs to your prescriber. Berberine can amplify glucose-lowering drugs, vitamin K can affect warfarin, and betaine HCl is not appropriate with acid-suppressing medication. Bring the bottles to your next appointment.

Does Telomere Benefits lengthen telomeres?

No, and the human data that does exist points the same way. The pooled trial evidence for telomerase-activating supplements is thin, largely industry-funded, and has not translated into any functional benefit [51]. Telomere Benefits is best understood as a multi-nutrient antioxidant formula.

Is DaVinci Labs gluten free and hypoallergenic?

The brand formulates to a hypoallergenic posture, so common offenders and unnecessary additives are left out. That is a formulation standard, not a guarantee for every allergy. Read the allergen statement on the bottle in your hand.
