Heart & Soil Grass Fed Whey Protein
Summary
Heart & Soil Grass Fed Whey Protein scores 96/100. A clean protein powder featuring grass-fed whey concentrate along with collagen and colostrum, delivering high-quality protein with immune and joint support benefits and no artificial additives. Heart & Soil partners with Light Labs (ISO 17025 accredited) for comprehensive independent testing: the published reports show glyphosate and AMPA not detected (tested Sep 8, 2025), mercury not detected, and lead, cadmium, and arsenic all below the lab's quantification limits (heavy-metals panel tested May 26, 2026). One of the cleanest verified protein powders on the market.

Glyphosate Not detected Not detected
Not detected — below detectable levels as defined by third-party lab tests. This is the strictest possible result: no measurable amount was found.
Light Labs comprehensive testing (tested Sep 8, 2025): glyphosate not detected. AMPA (glyphosate's breakdown product) also not detected.
AMPA (Glyphosate Metabolite) Not detected Not detected
Not detected — below detectable levels as defined by third-party lab tests. AMPA is the primary environmental breakdown product of glyphosate; testing for it catches degraded residues that a glyphosate-only test can miss.
Light Labs comprehensive testing (tested Sep 8, 2025): AMPA not detected.
Lead <0.12 mcg per serving Not detected
Below the laboratory's quantification limit — no measurable amount was found down to 0.12 micrograms per serving.
Light Labs comprehensive heavy-metals panel (ICP-MS, tested May 26, 2026): lead below the quantification limit of 0.12 mcg per serving.
Cadmium <3.22 mcg per serving Not detected
Below the laboratory's quantification limit — no measurable amount was found down to 3.22 micrograms per serving.
Light Labs comprehensive heavy-metals panel (ICP-MS, tested May 26, 2026): cadmium below the quantification limit of 3.22 mcg per serving.
Arsenic <0.2 mcg per serving Not detected
Below the laboratory's quantification limit — no measurable amount was found down to 0.2 micrograms per serving. For scale, a cup of brown rice typically contains around 10 micrograms of arsenic.
Light Labs comprehensive heavy-metals panel (ICP-MS, tested May 26, 2026): arsenic below the quantification limit of 0.2 mcg per serving.
Mercury Not detected Not detected
Not detected — below the laboratory's detection limit. This is the strictest possible result: no measurable amount was found.
Light Labs comprehensive heavy-metals panel (ICP-MS, tested May 26, 2026): mercury not detected.
Key ingredients 3
Grass-fed whey concentrateVery Good
Grass-fed whey concentrate is a high-quality protein source with a complete amino acid profile. It is derived from the milk of grass-fed cows, which may contain higher levels of omega-3 fatty acids and CLA compared to grain-fed counterparts. This ingredient is minimally processed, retaining more of its natural nutrients.
Benefits
Provides essential amino acids necessary for muscle repair and growth. May support immune function and overall health due to its nutrient-rich profile.
CollagenVery Good
Collagen is a protein that supports skin, joint, and bone health. It is typically derived from animal sources and is known for its role in maintaining the structural integrity of connective tissues. This ingredient is beneficial for those looking to improve skin elasticity and joint function.
Benefits
May improve skin hydration and elasticity, and support joint health by providing necessary building blocks for cartilage.
ColostrumVery Good
Colostrum is a nutrient-rich fluid produced by mammals in the first few days after giving birth. It is high in antibodies and growth factors, which can support immune function and gut health. This ingredient is valued for its potential to enhance immune response and promote gut integrity.
Benefits
Supports immune health due to its high antibody content. May promote gut health and overall well-being.
Processing
Unprocessed or Minimally Processed Foods
