Protein Powder Without Glyphosate

Why Should I Use a Glyphosate-Free Protein Powder?

Glyphosate is a herbicide (weed killer) used to protect crops from unwanted plants that compete for nutrients and water.

First introduced as Roundup, glyphosate has become one of the most widely used herbicides worldwide.

The US Department of Agriculture reports that as of 2025, more than 90 percent of soybeans and corn grown on US farms are genetically engineered to survive Roundup application.

As a result, these crops often contain detectable glyphosate residues (Food Chem, 2014).

Small amounts of glyphosate can also appear in other legumes (beans and peas) and grains, particularly oats and wheat, raising questions about potential health effects from repeated exposure.

Research suggests glyphosate exposure might be linked to several health concerns, though scientists continue to debate the level of risk.

Studies in animals and laboratory settings suggest that glyphosate exposure could potentially affect the nervous system and might also disrupt the gut microbiome (Environ Res, 2022).

The World Health Organization classifies glyphosate as a probable human carcinogen – a substance that probably causes cancer.

Which Protein Powders Are Glyphosate-Free?

Due to potential health concerns, many consumers choose to avoid glyphosate in their foods, beverages, and protein shakes and powders.

One common approach is choosing USDA Organic products, since organic certification prohibits glyphosate use.

That said, even USDA Organic foods can contain trace amounts of glyphosate due to:

• Environmental Drift: When conventional farms spray glyphosate, wind can carry it to nearby organic fields. Rain and irrigation water can also transport residues from treated areas.
• Contaminated Soil and Water: Glyphosate can remain in soil and water for extended periods. Previous contamination or agricultural runoff might affect current organic crops.
• Cross-contamination During Processing: Equipment used for both conventional and organic crops during harvesting, transport, or processing can transfer residues between products.
• Testing Gaps: USDA organic certification focuses on farming methods rather than final product testing. The certification does not require regular glyphosate testing, so trace contamination does not automatically disqualify a product from organic status.

For these reasons, experts often recommend avoiding ingredients with higher contamination risk.

Protein powder ingredients most likely to contain glyphosate include soy, whey (from cows that eat glyphosate-treated feed), and peas.

Look for companies that test their protein powders for glyphosate and share the results publicly.

What Is the Best Glyphosate-Free Protein Powder?

Many plant-based protein powders contain detectable glyphosate residues.

While current regulatory assessments suggest trace amounts of glyphosate might not harm human health, avoiding exposure when possible could be a prudent choice.

The most reliable approach is purchasing from brands that conduct third-party testing.

Drink Wholesome, for instance, uses independent laboratory testing and publishes their test results.

It also avoids ingredients with higher contamination risk, including soy, whey, and peas.
