Common Questions About Protein Manufacturers (FAQs)
Q1: How do I know if a manufacturer is FDA compliant?
Look for proof of FDA registration and ask for their cGMP certificate. Manufacturers must meet specific Good Manufacturing Practices to legally operate in the U.S. food and dietary supplement industry.
Q2: Can I create my own custom protein formula?
Yes. Most full-service protein manufacturers offer custom formulation services, including ingredient sourcing, flavor matching, and lab testing.
Q3: What’s the minimum I need to invest to get started?
Some manufacturers allow private label entry with as little as $5,000 to $10,000, depending on order size, packaging, and formulation.
Q4: Is plant-based protein more expensive to manufacture than whey?
Yes, often. Plant-based proteins require additional masking agents, flavor enhancers, and specialized filtration systems. Expect costs to be 10–20% higher than standard whey.
Q5: How long does it take to go from concept to shelf-ready product?
Typical timeline:
-
Formulation & samples: 2–4 weeks

Label design & compliance review: 1–2 weeks
-
Production & packaging: 4–6 weeks
So, a total of 6 to 10 weeks is standard.
