Is Levels Protein Powder Safe? Clean Label Certified Whey Analysis (2026)
✅ Direct Answer: Is Levels Protein Powder Safe?
Yes — with one important caveat. Levels Whey Protein holds a Clean Label Project Purity Award, placing it among fewer than 30% of brands certified for heavy metal safety. It has not been independently tested by Consumer Reports. Its grass-fed whey base is inherently low-risk, and we rate it Cleared — Consumer Reports verification pending.
How We Analyzed Levels Whey Protein
Independent Data Sources: Clean Label Project Purity Award certification & Consumer Reports October 2025 + January 2026 Testing Data
Our 4-Step Safety Protocol:
- Source: We aggregate verified data from third-party labs (Consumer Reports, Clean Label Project, NSF).
- Benchmark: Contamination is measured against California Prop 65 safe harbor levels (0.5 µg/day lead).
- Categorize: Products are ranked as Safe, Limit Use, or Avoid based on toxic accumulation.
- Recommend: Where testing gaps exist, we flag them clearly rather than making unsupported assumptions.

✅ Levels Protein: What the Data Shows
Levels is the most searched brand on this site without a dedicated safety article — and you deserved a straight answer. Here it is.
📋 Table of Contents
What the Testing Data Actually Shows
Levels became the third most searched brand on CleanProteinList.com without ever having a dedicated article here. That's because Levels has grown fast — from a DTC startup to Costco shelves in 13 states — and consumers who discovered it wanted to know the same thing they want to know about every brand: does it have a lead problem?
The honest answer requires separating two things: what has been tested, and what that testing means.
What Has Been Tested
| Testing Source | Levels Status | What It Covers |
|---|---|---|
| Clean Label Project | ✅ Purity Award Certified | 400+ contaminants including heavy metals, pesticides, plasticizers |
| Consumer Reports (Oct 2025 / Jan 2026) | ❓ Not tested | Lead, cadmium, arsenic, mercury at Prop 65 per-serving benchmarks |
| NSF Certified for Sport | ❓ Not certified | Banned substances; heavy metals at acute (not chronic) limits |
The picture that emerges: Levels has substantive independent certification through Clean Label Project, but hasn't been subjected to Consumer Reports' more specific per-serving benchmark testing at Prop 65 limits.
✅ Our Rating: Cleared — Consumer Reports Verification Pending
CPL distinguishes between products that have been tested and cleared (Consumer Reports verified), products with strong third-party backing but a data gap (Levels), and products with no independent data at all. Levels falls in the middle category — meaningfully better than untested brands, not yet at the full verification standard of Consumer Reports-confirmed products.
This is not vague concern. It is an honest accounting of what exists.
What the Clean Label Project Purity Award Actually Means
The Clean Label Project is an independent nonprofit that tests consumer products for contaminants not covered by standard label requirements. Their Purity Award is not a marketing certification — it requires passing independent laboratory screening across a broad contaminant panel.
What the Purity Award Tests
✅ Covered by Clean Label Purity Award:
- Heavy metals: Lead, cadmium, arsenic, mercury
- Pesticide residues: Over 200 agricultural chemicals
- Plasticizers: BPA, BPS, and phthalates
- Mycotoxins: Mold-derived toxins
- Antibiotics and hormones
⚠️ Important distinctions from Consumer Reports methodology:
- Threshold differences: Clean Label Project uses its own internal benchmarks, while Consumer Reports uses California Prop 65 safe harbor (0.5 µg/day lead) as the per-serving cutoff
- Lot sampling: Consumer Reports tests 2–4 distinct production lots per product to catch batch variation; Clean Label Project's sampling methodology varies
- Published specifics: Consumer Reports publishes exact µg/serving figures; Clean Label Project issues pass/fail certification
Bottom line: The Purity Award is real, substantive, and meaningful. Fewer than 30% of protein brands pass it. It confirms that Levels has submitted to independent scrutiny and cleared it. The gap relative to Consumer Reports is about methodology specificity, not about whether Levels has been tested at all.
💡 How Levels Used This Certification
Levels specifically timed its H-E-B retail expansion to coincide with the Consumer Reports October 2025 study release, explicitly positioning the Purity Award as its answer to the safety conversation. That's a brand that knows its certification matters and is leaning into it — not hiding from scrutiny.

Why Whey Concentrate Is Inherently Safer
One of the most consistent findings across Consumer Reports' 28-product test dataset is the gap between whey-based and plant-based proteins. Understanding where Levels sits in that landscape matters for putting its certification in context.
✅ Whey-Based Proteins (Levels is here)
- Derived from dairy — cows filter heavy metals before they reach milk
- Average lead levels 9× lower than plant proteins in CR testing
- 6 of Consumer Reports' 7 safest products were whey-based
- Grass-fed sourcing adds no meaningful heavy metal risk
⚠️ Plant-Based Proteins (Levels is not here)
- Plants absorb heavy metals directly from soil through roots
- 14 of 15 plant proteins tested by CR exceeded safe limits
- Organic certification makes it worse — 3× more lead on average
- Pea, rice, hemp all shown to concentrate lead in protein fraction
Levels uses grass-fed whey protein concentrate — the same protein base that underpins some of Consumer Reports' top-ranked products. The protein source alone puts Levels in a fundamentally different risk category than the plant-based products that dominate the contamination rankings.
Whey Concentrate vs Whey Isolate: Does It Matter for Safety?
Levels uses whey concentrate rather than isolate, which is a meaningful ingredient choice worth understanding — though not for safety reasons.
| Attribute | Whey Concentrate (Levels) | Whey Isolate (Dymatize, Momentous) |
|---|---|---|
| Processing level | Less processed — minimal filtration | More processed — extensive filtration |
| Protein % | ~70–80% | ~90%+ |
| Lactose | Small amounts present | Negligible |
| Heavy metal risk | Low (same whey source) | Low (same whey source) |
| Consumer Reports results | Body Fortress (concentrate) — non-detect lead | Dymatize ISO 100 (isolate) — #2 safest overall |
The safety profile of whey concentrate and whey isolate is effectively equivalent. The distinction matters for protein concentration, lactose tolerance, and price — not heavy metal contamination. Consumer Reports' #1 and #5 ranked products both use whey concentrate as part of their base.
Levels vs Verified-Safe Alternatives: How It Stacks Up
The most useful comparison for Levels is the bracket of verified-safe whey proteins at similar price points. Here's where Levels sits honestly:
| Brand | Price/Serving | Consumer Reports | Clean Label | Our Rating |
|---|---|---|---|---|
| Body Fortress Whey | $0.67 | ✅ Clean Label (non-detect lead) | ✅ Purity Award | ✅ Verified Safe |
| Optimum Nutrition Gold Standard | $0.75 | ✅ #5 ranked (below detection) | ✅ Purity Award | ✅ Verified Safe |
| Equate Whey (Walmart) | $0.60 | ✅ #10 ranked (0.27 µg — 55% of limit) | Not certified | ✅ Verified Safe |
| Levels Whey Protein | $0.75 | ❓ Not tested | ✅ Purity Award | ✅ Cleared (CR pending) |
| Dymatize ISO 100 | $1.25 | ✅ #2 ranked (below detection) | ✅ Purity Award | ✅ Verified Safe (dual) |
| Momentous Whey Isolate | $2.00–2.50 | ✅ #3 ranked (below detection) | NSF Sport | ✅ Verified Safe |
The table tells an honest story: at $0.75/serving, Levels competes directly with Optimum Nutrition Gold Standard in price. ON has the edge in verification depth (Consumer Reports tested). Levels has the edge in ingredient simplicity (6–8 ingredients vs ON's more complex formula) and sourcing story (grass-fed, hormone-free). For daily users who have price sensitivity, ON is the safer choice by verification. For users who specifically prioritize minimal ingredients and grass-fed sourcing at this price point, Levels is a reasonable option with real third-party backing.
✅ The Case for Levels at This Price Point
At $0.75/serving with a Clean Label Purity Award, Levels is doing something no other brand at this price tier has achieved: minimal ingredients (6–8), grass-fed sourcing, no artificial anything, and independent third-party certification. Body Fortress is cheaper but uses a more processed blend. ON Gold Standard is equally verified but has more additives. Levels' ingredient philosophy is genuinely differentiated in its price category.
Levels vs Ascent: The "Natural" Premium Comparison
Consumers often compare Levels with Ascent, another "clean ingredient" brand. The distinction is important:
| Levels | Ascent | |
|---|---|---|
| Price | $0.75/serving | $2.50–3.00/serving |
| Protein type | Whey concentrate (grass-fed) | Whey isolate (native whey) |
| Consumer Reports | Not tested | Not tested |
| Clean Label Project | ✅ Purity Award | ❌ Not certified |
| NSF Certified for Sport | Not certified | ✅ Certified |
| Verdict | Cleared at budget price, Clean Label backed | No heavy metal certification despite premium price |
This comparison is striking: Levels has more heavy metal verification than Ascent at one-quarter the price. Ascent's NSF Sport certification tests for banned athletic substances, not heavy metals at safe daily limits. Levels' Clean Label Purity Award explicitly covers heavy metals. For anyone weighing a "clean" premium brand, Levels delivers more relevant safety evidence per dollar.
Which Levels Products Have Clean Label Certification?
The Clean Label Project Purity Award covers Levels' whey protein products specifically. As with all brands in our database, we flag untested product lines rather than assume the same certification applies across the board.
| Product | Certification Status | Recommendation |
|---|---|---|
| Levels 100% Whey Protein Concentrate (Vanilla Bean, Double Chocolate, Unflavored) |
✅ Clean Label Project Purity Award | CLEARED — use with confidence |
| Levels 100% Micellar Casein Protein | ❓ Certification not confirmed for this product | Unknown — casein is dairy-based and inherently lower risk, but verify independently |
| Any future Levels plant-based products | ❓ Not applicable currently | Would require separate evaluation — plant proteins carry significantly higher contamination risk |
Our recommendation: Stick to Levels' whey concentrate products — the product line covered by their Purity Award. If Levels launches plant-based products, those would require independent evaluation regardless of brand reputation. Whey and plant protein safety profiles are not interchangeable.
Levels at Costco: A Note on Bulk Buying
Levels has been expanding rapidly at Costco — 187 warehouses across 13 states as of early 2026, with Pacific Northwest expansion announced in February. For Costco shoppers comparing options on the shelf, here's the honest assessment:
Costco Whey Protein Safety Rankings (Current)
- MuscleTech 100% Mass Gainer — Consumer Reports #1 (lead not detected) — best for bulking
- Dymatize ISO 100 — Consumer Reports #2 (lead below detection) — best isolate
- Optimum Nutrition Gold Standard — Consumer Reports #5 (lead below detection) — best overall value, fully verified
- Levels Whey Protein — Clean Label Purity Award, not CR tested — cleared, pending full verification
- Kirkland Signature Whey — No independent testing data — unknown
If both ON Gold Standard and Levels are on your Costco shelf, ON has the deeper verification stack. If Levels is available and ON isn't, Levels is a reasonable choice — meaningfully better than unverified alternatives, and not a brand you should avoid.
Who Should Use Levels — and Who Should Consider Alternatives
✅ Levels Is a Strong Choice If You:
- Want minimal ingredients (6–8) at a competitive price
- Prioritize grass-fed, hormone-free dairy sourcing
- Are buying at Costco and ON Gold Standard isn't available
- Want Clean Label certification without paying the Momentous or Truvani premium
- Are not a competitive athlete needing NSF Certified for Sport
- Are comfortable with "cleared with one data gap" vs "fully dual-verified"
⚖️ Consider Alternatives If You:
- Want the strongest possible verification stack — go with Optimum Nutrition (Consumer Reports #5) or Dymatize ISO 100 (#2)
- Need NSF Certified for Sport for athletic drug testing compliance — go with Momentous
- Are on the tightest possible budget — Body Fortress ($0.67) has both Clean Label and Consumer Reports verification
- Need plant-based protein — OWYN Pro Elite is the only verified-safe plant option
- Are pregnant or buying for children — the higher-verification options reduce even theoretical risk
The practical reality: For the vast majority of healthy adults using protein powder regularly, Levels' Clean Label Purity Award plus its whey-based formula is a solid foundation. The "Consumer Reports verification pending" flag isn't a warning — it's an honest gap marker. We flag the same gap for every untested brand. Levels has more going for it than most.
Frequently Asked Questions
Is Levels protein powder safe?
Yes, with the understanding that "safe" is supported by Clean Label Project certification, not yet Consumer Reports testing. Levels Whey Protein holds a Purity Award from Clean Label Project — a rigorous independent certification covering 400+ contaminants including heavy metals. Its grass-fed whey base is inherently lower risk. We rate it Cleared — Consumer Reports verification pending.
Does Levels protein powder have lead?
No specific per-serving lead figure has been published by Consumer Reports. The Clean Label Project Purity Award includes heavy metal screening, and Levels passed. Its whey protein base places it in the lowest contamination category — Consumer Reports found whey proteins had on average nine times less lead than plant-based proteins. We have no data suggesting a lead problem with Levels; we simply note that CR testing would add another verification layer.
How does Levels compare to Optimum Nutrition Gold Standard?
ON Gold Standard is the stronger verified choice; Levels is the cleaner-ingredient choice at the same price. ON has been tested by Consumer Reports (#5, lead below detection) and holds a Clean Label Purity Award — dual verification. Levels holds the Purity Award but hasn't been Consumer Reports tested. Both are ~$0.75/serving. If verification depth is your priority, go with ON. If minimal ingredients and grass-fed sourcing matter more at this price point, Levels is defensible.
Is Levels protein available at Costco?
Yes, and expanding. As of early 2026, Levels is in 187 Costco warehouses across 13 states — California, Texas, Hawaii, Louisiana, Kansas, Arkansas, Oklahoma, and Pacific Northwest states — plus Costco.com. It's the 5.64lb bag at approximately $69.99, which works out to roughly $0.75/serving for 80 servings. It's also at Walmart, Target, Kroger, H-E-B, and Amazon.
Is Levels better than Ascent Native Fuel?
From a heavy metal verification standpoint, yes. Levels has a Clean Label Project Purity Award covering heavy metals. Ascent has NSF Certified for Sport, which tests for banned substances but not heavy metals at safe daily consumption limits. Levels is also dramatically cheaper ($0.75 vs $2.50–3.00/serving). Ascent's native whey processing gives it a better amino acid profile, but that doesn't affect safety. On the evidence available, Levels has more relevant heavy metal certification than Ascent at a fraction of the cost.
What is the Clean Label Project Purity Award?
A substantive independent third-party certification for consumer product purity. Clean Label Project tests for 400+ contaminants including heavy metals (lead, cadmium, arsenic, mercury), pesticide residues, plasticizers (BPA, phthalates), and mycotoxins. Fewer than 30% of protein powder brands pass it. It is not as granular as Consumer Reports' per-serving lead benchmarks against Prop 65 limits, but it is meaningful and requires genuine independent testing — not self-reported data.
Should I switch from Levels to something else?
Not necessarily. If you're currently using Levels and it's working for you, there's no red flag telling you to stop. The Clean Label Purity Award is a real certification, and grass-fed whey concentrate is a low-risk protein base. If you want maximum verification certainty, switching to Optimum Nutrition Gold Standard or Dymatize ISO 100 would give you Consumer Reports confirmation. But Levels is not a brand you should be worried about — it's one where the evidence we have is positive.
Why hasn't Consumer Reports tested Levels?
Consumer Reports tests the highest market-share brands. Both their October 2025 and January 2026 studies focused on products purchased anonymously at major mass retailers by total sales volume. Levels has been growing rapidly — from targeted DTC to Costco shelves in 13 states — but may not yet have reached the market penetration that drives Consumer Reports' brand selection. That's a consequence of being a newer entrant, not evidence of anything concerning.
