Common questions

Is Prolon L-protein healthy?

Prolon L-protein scores 15/100 on Tallow — our avoid band. That number comes from what is on the label: the ingredients, how processed it is, and what it is packaged in. It is not a verdict on your diet — Tallow does not weigh calories, portion size or how often you eat it, so a high score means the ingredients are clean, not that the food is unlimited.

What is in Prolon L-protein?

Prolon L-protein lists 34 ingredients, starting with Zinc Oxide, Vitamin B5, Vitamin a, Vitamin d and Cupric Citrate. Ingredients are listed in descending order by weight, so the first few make up most of what you are eating.

Does Prolon L-protein contain seed oils?

No. Nothing in Prolon L-protein’s ingredient list matches a seed oil — canola, soybean, corn, cottonseed, grapeseed, sunflower, safflower, rice bran or peanut oil, or an unspecified "vegetable oil".

How processed is Prolon L-protein?

Prolon L-protein is NOVA group 3: processed, but not ultra-processed. NOVA runs 1 to 4, where 1 is whole food and 4 is ultra-processed.

How does Prolon L-protein compare to other protein powders?

At 15/100 Prolon L-protein scores worse than most protein powders we have scored. A higher-scoring option in protein powders is Truvani Plant Based Protein, Unflavored & Unsweetened, 19.75 oz at 100/100.

Is Prolon L-protein organic?

Yes. Prolon L-protein carries USDA Organic certification, which is worth +5 points in the score above.

Has Prolon L-protein been lab tested?

Not yet. No independent lab has published results for Prolon L-protein, so its score is based on its ingredient list, processing and packaging alone.
