The 5 Best Vegan Protein Powders with Less Heavy Metals
|
Protein powders fill nutritional gaps and support muscle building, making them a staple in many vegan pantries.
But it's worth remembering that some vegan protein powders can contain higher levels of trace minerals—like lead, mercury, cadmium, and arsenic—due to the soils they are grown in. These naturally occur in all plant-based foods.
In October 2025, Momentous published a detailed response to a Consumer Reports article on protein powders. The response addresses concerns around trace heavy metals, testing methodology, and transparency. It emphasizes that plant-based protein powders naturally contain trace minerals due to soil and crop biology, and that comparing them directly with whey proteins (or different flavors) can be misleading.
It points out that the Consumer Reports article used California’s Proposition 65 “level of concern” (0.5 µg/day for lead) as a benchmark, which is a legal-warning threshold rather than a scientifically derived safety limit, and that it is much more conservative than international regulatory safety thresholds.
It also notes that the version of the plant protein product referenced by Consumer Reports was a previous-generation formula (“v1”) which has been replaced by a new formulation (“v2”) in 2024 with upgraded sourcing, improved purity standards, and new suppliers.
For readers evaluating vegan protein powders with an eye to heavy metals, this transparency and context may help you interpret test results and brand claims more fully, especially when balancing purity, ingredient sourcing, formulation, cost, and certifications.
The Number One Thing to Avoid in Vegan Protein Powders If Heavy Metals Are a Concern
While “organic” often signals healthier choices, the reality can be different for plant-based protein powders. The organic label indicates that the plants were grown in organic soil, which can sometimes accumulate higher levels of heavy metals such as arsenic, cadmium, and lead.
As such, we’ve avoided naming any organic plant protein options on this list. We’ll start it with Momentous’ own plant-based protein supplement, which has been upgraded with improved sourcing, better taste and mixability, and zero gums, fillers, stabilizers. Before we do that, however, let's show some real-world food context to illustrate how trace minerals in our foods are a normal part of agriculture:
For example, some studies have shown:
Tomato (one medium, ~150g) — ~3.2 mcg
Source: roczniki.pzh.gov.plApple (one medium, ~180g) — ~1.0 mcg
Source: link.springer.comStrawberries (8–10 pieces, ~100g) — ~1.0–1.5 mcg
Source: nature.com
The trace levels found in Momentous protein powders are comparable to those found naturally in fruits and vegetables, everyday foods recognized as safe and nutritious.
The lead amounts in our current Momentous Plant Protein for comparison are below and can all be found here on our website:
Cappuccino flavor 0.29 µg
Chocolate Flavor 0.54 µg
Vanilla Spice Flavor 0.48 µg
Note that because we use only natural ingredients in our formulations, it’s normal to see a small range in test results. The trace minerals present in our Plant Protein come from the natural variability of agricultural ingredients, not from contamination. We closely monitor every batch and uphold strict internal standards, ensuring each product meets our quality thresholds before it ever reaches customers.

What to Look for When Choosing a Vegan Protein Powder
While each person has something unique that they’re looking for out of their protein powder, here are a few of the key factors we think you should consider as you evaluate your options:
1. Protein Source
Vegan protein powders typically derive their protein from plants like peas, rice, soy, and hemp protein. Each source offers a unique balance of essential amino acids and nutritional benefits.
For instance, pea protein is rich in lysine, while rice protein offers a good methionine profile. Choosing a powder that uses a blend of sources can ensure a more complete amino acid profile, akin to animal proteins.
2. Flavor and Sweetness
Taste is a major factor in sticking with a protein supplement regimen. Look for powders that strike a balance between being flavorful and not overly sweet.
Natural sweeteners like stevia or monk fruit can be preferable, but it's important to sample a product to make sure its taste aligns with your preferences. Some powders are also available in unflavored varieties, which are versatile for blending into savory and sweet dishes alike.
3. Transparency Around Heavy-Metal Testing & Product Versions
While any vegan protein powder should be mindful of heavy-metal content, the key is how the brand frames its testing, publishes results and uses real-world context. Momentous emphasises that plant-based ingredients inherently absorb trace minerals from soil and water, much like everyday plant foods, and that the metric should not be heavy‐metals alone, but also the complete product formulation, processing, sources, and certifications.
Also consider: Has the product gone through major formulation or sourcing changes? Are heavy-metal results published per batch? Are ingredients transparent and minimal (i.e., less filler, fewer artificial additives)? These attributes suggest a brand takes a holistic and evidence-based approach rather than only marketing “low heavy metals.”
4. Certifications
Certifications can help you gauge the quality and purity of a protein powder. Look for labels like NSF Certified for Sport, Informed Sport, or Non-GMO Project Verified.
These certifications indicate that the product has undergone rigorous testing for contaminants and meets strict production standards. Remember that USDA Organic could present a slight risk of higher heavy metal content.
5. Nutritional Content
Beyond protein, check the levels of other nutrients such as fiber, essential fats, vitamins, and minerals. A good vegan protein powder might also offer added health benefits from superfoods, antioxidants, and digestive enzymes to support overall wellness.
6. Digestibility
Consider how well your body tolerates the protein. Some sources, like pea protein, might be easier to digest, while others might require additional digestive support. If you have sensitivities, look for powders that are hypoallergenic or free from common allergens like gluten and soy.
7. Sustainability
For many vegans, the environmental impact of their food choices is as important as the nutritional value. Research the brand’s sourcing and manufacturing processes to ensure they align with your values concerning sustainability and ethical practices.
