1. Naked Grass-Fed Whey Protein Powder – Top Pick

naked whey protein
  • Diet Type: Build Muscle, Recovery, Cutting
  • Suitable for Vegans: No
  • Protein Source: Grass-Fed Whey
  • Serving Size: 30-38g
  • Price per Serving: ~$1.25-1.58
  • Protein Percent of Calories: 62-83%
  • Calories: 120-160
  • Protein: 25g
  • Carbohydrates: 3-8g
  • Fat: 2-3g
  • Sugar: 2-7g
  • Company Founded: 2014
  • Recommended by Athletes: Kenzie MarianoDaniel Victor

Starting off our list, and the best pick for a heavy metal free protein powder, is Naked’s grass-fed whey. Committed to delivering some of the highest quality supplements on the market, Naked is a natural fit for this list because of their rigorous third-party testing.

Their products are independently tested using ICP Mass Spectrometry to ensure they contain very low levels of heavy metals in each serving. As the results on their product page show, they have <0.30 MCG of arsenic, and <0.15 MCG of cadmium, lead, and mercury in each serving. These results should give consumers worried about heavy metals the confidence to purchase Naked’s products worry-free.

Aside from this, Naked offers an all-around great whey protein. With a solid 25g of protein per serving, and a high-quality formula using only 3 ingredients, including grass-fed whey, you can be sure you’re getting a great product. The one downside is that because of the varying macros between flavors, you will be getting a slightly pricier and less concentrated protein if you opt for chocolate, vanilla, or strawberry over the unflavored variety. 

58.5 EXPERT SCORE

It’s have <0.30 MCG of arsenic, and <0.15 MCG of cadmium, lead, and mercury in each serving. These results should give consumers worried about heavy metals the confidence to purchase Naked’s products worry-free.

Positives:

  • Independently tested for heavy metals
  • Comes from high quality, grass-fed whey
  • Unflavored option has some of the best macros on our list

Could be better:

  • Macros vary between flavors
  • Unflavored variety won’t appeal to everyone, despite having great macros

2. Promix Whey Protein Powder – Runner Up

Promix Whey Protein Powder
  • Diet Type: Build Muscle, Recovery, Cutting
  • Suitable for Vegans: No
  • Protein Source: Grass-Fed Whey
  • Serving Size: 31-40g
  • Price per Serving: ~$0.93-1.24
  • Protein Percent of Calories: 63-83%
  • Calories: 120-160
  • Protein: 25g
  • Carbohydrates: 3-10g

  • Sugar: 1-5g
  • Company Founded: 2011

Next on our list, we have Promix’s Whey Protein Powder. This product has a lot of similarities to Naked’s whey, including that it’s independently tested for heavy metals.

Similar to Naked, Promix uses ICP Mass Spectrometry to test for metals. Their results show <5.0 ppb for mercury and lead, and <10.0 ppb for cadmium and arsenic which confirms the low content of heavy metals in the supplement. They also test for other contaminants like the pesticide, glyphosate which has a very low result as well. 

Promix also has very similar macros to Naked’s whey, with both supplements containing 25g of protein in each serving, and having a nearly identical range of protein concentration between flavors. Promix also has a similarly simple, high-quality formula, using grass-fed whey. Where Promix wins some points over naked is that it comes at a noticeably lower price point.

Why we ultimately chose Naked as our top pick over Promix is that their protein is that some reviews suggest a poor mixability and flavor. Otherwise, this is a great pick for those looking to avoid heavy metals.

Positives:

  • Reviews suggest poor mixability as well

3. Naked Pea Protein

Naked Pea Protein
  • Diet Type: Building Muscle, Improving Recovery, Cutting
  • Suitable for Vegans: Yes
  • Protein Source: Pea Protein Isolate
  • Serving Size: 30-38g
  • Price per serving: $0.76-0.97
  • Protein Percent of Calories: 62-90%
  • Calories: 120-160
  • Protein: 25-27g
  • Carbohydrates: 2-8g
  • Fat: 0.5-4g
  • Sugar: 2-5g
  • Company Founded: 2014
  • Recommended by Athletes: Kenzie MarianoDaniel Victor

Next up we have another option from Naked, which is its Pea Protein. This is the first of 3 vegan options on our list, and the cheapest protein on our list by a decently wide margin, making it the best vegan protein powder without heavy metals.

Similar to Naked’s whey, its pea protein is independently tested for heavy metals. The results show the same levels of each heavy metal for Naked’s pea and whey. Arsenic is below <0.30 MCG per serving, and cadmium, lead, and mercury are all below <0.15 MCG. Once again, if you’re truly concerned about the presence of heavy metals, buying one of these independently tested products is the best way to make sure there is very little present in your protein.

Looking at the macros, Naked offers one of the highest protein, most densely packed vegan protein supplements on the market. At 27g per serving and a 90% protein concentration for the unflavored option, macros don’t get much better than that! Keep in mind that if you go for chocolate or vanilla instead, you will be getting a slightly more expensive shake with a much lower protein concentration.

Also, it’s worth mentioning that pea protein has a different consistency to whey protein, and does not mix nearly as smoothly. Keep this in mind if you’ve never tried pea protein before buying this product.

57 EXPERT SCORE

Similar to Naked’s whey, its pea protein is independently tested for heavy metals. The results show the same levels of each heavy metal for Naked’s pea and whey. Arsenic is below <0.30 MCG per serving, and cadmium, lead, and mercury are all below <0.15 MCG.

Positives:

  • Independently tested similar to Naked’s other products
  • Great macros, especially for a vegan protein
  • Cheapest option on our list

Could be better:

  • Texture is very different from whey and will put some off
  • Concentration for flavored varieties is much lower than the flavored option

4. Ora Organic Vegan Protein Powder

Ora Organic Vegan Protein Powder
  • Diet Type: Building Muscle, Improving Recovery, Cutting
  • Suitable for Vegans: Yes
  • Protein Source: Ora Protein, Superfood, & Greens Blend (Pea Protein, & Rice Protein)
  • Serving Size: 29-32.5g
  • Price per serving: $1.65
  • Protein Percent of Calories: 68-84%
  • Calories: 120-130
  • Protein: 22-23g
  • Carbohydrates: 1-5g
  • Fat: 2.5-3g
  • Sugar: 0g
  • Company Founded: 2015
  • Recommended by Athletes: CoupleyFittDr. Sam AttardWhitney Fransway

Next on our list we have another vegan option, this time coming from Ora Organic.

Similar to the last 3 products on our list, Ora proudly tests all its supplements to ensure they don’t contain any heavy metals. As it says on their website, they independently test for heavy metal content, as well as microbial contaminants, and pathogens. The one downside here is that they don’t actively display their testing results, so it’s difficult to say how much of each heavy metal Ora’s products actually contain.

Moving on to Ora’s macros, they don’t have the best breakdown on our list. While 22-23g of protein is decent for a vegan supplement, it’s significantly lower than Naked’s pea protein. Especially at $1.65 per serving, there is a noticeable jump in price from Naked as well.

What does win Ora some points back from Naked is its long list of “superfood” ingredients like kale, acai, and blueberry, which help to boost Ora’s micronutrient profile. These are not must-have ingredients for protein powder, but this is a good option if you want to make your protein shake a little richer in micronutrients.

It’s worth noting that this protein will also have a different flavor and texture to whey, especially if you’re buying the unflavored option. Although some people won’t mind, it’s worth considering if you’re planning on making the switch from whey.

5. Pure Protein 100% Whey

Pure Protein 100% Whey
  • Diet Type: Building Muscle
  • Suitable for Vegans: No
  • Protein Source: Whey Protein Concentrate & Isolate
  • Serving Size: 39.6-41.2g

  • Sugar: 2g

Next, we have another whey option, this time coming from Pure Protein.

One of the main reasons we’ve chosen this protein for our list is for its inclusion in an article on consumerreports.org about heavy metals in protein powders. This article highlighted a study done by the Clean Label Project which tested various proteins for heavy metals, pesticides, and BPA. Ultimately the product that got the best score was Pure Protein, specifically their vanilla whey. Although the company does not directly test for heavy metals, this study should give buyers confidence in Pure Protein’s quality.

With that being said, this is one of the pricier options on our list at nearly $2 per serving. Also, at a 63% protein concentration, it is one of the least dense proteins on our list. Also, at 160 calories per serving, this is a great choice for those looking to bulk up.

While its recommendation from the Clean Label Project is a great seal of approval, the tradeoff is a more expensive, less densely packed protein.

6. Sunwarrior Vegan Protein

Sunwarrior Vegan Protein
  • Diet Type: Building Muscle, Improving Recovery, Cutting
  • Suitable for Vegans: Yes
  • Protein Source: Proprietary Protein Blend (Organic Pea Protein, Hemp Seed Protein, Goji Berry)
  • Serving Size: 25g
  • Price per Serving: ~$1.26
  • Protein Percent of Calories: 71-76%
  • Calories: 90-100

  • Fat: 2-2.5g
  • Sugar: 0-1g
  • Company Founded: 2008

Up next, and the last vegan protein on our list, is Sunwarrior.

While Sunwarrior isn’t as upfront about heavy metals in their products, if you do a little digging, you can see that they do actually test for heavy metals. They use a certified-third party lab for all their testing. Although they do not share their exact results, they do state that their product meets necessary standards for heavy metal content. It is unclear why Sunwarrior isn’t as upfront about this as some of the other companies on our list, but nonetheless, they do fully test for heavy metals in all their products.

In terms of nutrition, Sunwarrior is a solid vegan protein. Although it has the lowest protein content on our list at 16-19g per serving, it’s relatively affordable at just over a dollar per serving. Where it stands out is its taste and texture, being one of the most delicious plant-based proteins on the market. 

55.5 EXPERT SCORE

7. Biochem Whey Protein

Biochem Whey Protein
  • Diet Type: Cutting
  • Suitable for Vegans: No
  • Protein Source: Whey Isolate
  • Serving Size: 24-25.3g
  • Price per Serving: ~$1.86

Finally, we have BioChem’s Whey Protein, which earns a spot on our list for a similar reason to Pure Protein.

Just like Pure Protein, BioChem was featured in consumerreports.org's article on the Clean Label Project’s study. It also received a top 5 score in terms of their criteria, largely based on heavy metal content. Once again, although Biochem does not appear to independently test themselves, these results should give anyone worried about heavy metals confidence to buy.

Once again, similar to Pure Protein, Biochem loses points based on its price and macro breakdown. At ~$1.86 per serving, it is one of the most expensive options on our list. Also, although it has a great protein density score of 89%, at only 20g of protein per serving, it has one of the lowest protein contents per portion on our list.

What Are Heavy Metals And What Are The Dangers?

The main heavy metals that are of concern are lead, cadmium, mercury, and arsenic, however other metals like zinc and copper may be of concern as well. These primarily get into food products through metals in soil that are absorbed by plant ingredients during farming. Food and water also can be contaminated at any stage of the food web and supply chain.

While it’s unlikely any product will expose you to high levels of heavy metals at once, there are dangers associated with long term exposure to small amounts. These primarily include neurological dysfunction, insomnia, nausea, and chronic tiredness, amongst others. Overall, although the health risks associated with heavy metals aren’t fully understood, it appears consuming them in low levels is .

Is This A Real Problem, Heavy Metals In Protein Powders?

As shown by the Clean Label Project mentioned earlier in our article, out of the 134 products they screened, many protein powders did in fact contain high levels of heavy metals. Although most of these do not have high enough levels to cause effects right away, as previously mentioned, prolonged exposure may lead to some pretty serious health issues. It does also appear like heavy metals in whey protein are less common than heavy metals in vegan proteins.

How To Choose A Protein Without Heavy Metal Contamination?

Some of the best ways we recommend checking if a protein has high heavy metal content is to check the company’s independent testing results, or to see how they stack up based on the Clean Label Project’s results. This way you can be confident the company’s you’re buying from are committed to keeping their products free from heavy metals.

FAQ

Do All Protein Powders Have Metal?

It is virtually impossible to find any food product that doesn’t contain at least trace amounts of heavy metals. However, it is only of concern when these products do not test for heavy metal content, and potentially have very high amounts of these contaminants.

What Proteins Do Not Contain Heavy Metals?

The best way to find proteins that contain minimal levels of heavy metals is to check their independent testing results, or to see how they’re rated by the Clean Label Project. Just keep in mind that all proteins will have some minute level of heavy metals.

Conclusion

It’s a good idea to find a protein with minimal levels of heavy metals because of the potential health problems long-term exposure to these elements can cause. Our top pick for a protein free from heavy metals is Naked’s Grass-Fed Whey Protein Powder, however, all the options on our list are great picks as well!

  1. Hi!

    Sometimes i use peanut butter powder. I assume it is classified as a food so it is regulated. Do you have any data on peanut butter powder? Most times I use the Walmart brand. It is a little less expensive than the 3 d

    Thank you

  2. Hey @Cynthia!
