Know before you scoop!

Still not sure? Our team offers free consultations at both Fort Wayne locations.

What type of protein is best for me? +

It depends on your goals! Whey isolate is ideal for lean muscle with minimal carbs, whey concentrate is great for general fitness, and plant-based options work for dairy-free diets. Visit us in-store for a free consultation and we'll help you find the perfect fit.

How much protein do I need daily? +

Most active adults need 0.7-1g of protein per pound of body weight. If you weigh 180 lbs, aim for 126-180g daily. Our staff can help you dial in the right amount based on your specific activity level and goals.

Can I use protein powder as a meal replacement? +

Yes! Many of our proteins work great as a meal replacement when blended with fruits, nut butter, or oats. For a complete meal, pair your protein shake with healthy fats and carbohydrates to hit your macro targets.

Do you offer samples or flavor recommendations? +

Absolutely! Visit either of our Fort Wayne locations and our team can help you sample flavors before committing to a full tub. We know how important taste is. Life's too short for protein you dread drinking.

Is your protein third-party tested? +

We only carry brands that undergo third-party testing for purity, potency, and banned substances. Quality is non-negotiable. It's why customers have trusted us for 15+ years in Fort Wayne.

What's your return policy on supplements? +

Unopened items may be eligible for return at Complete Health's discretion. Opened products cannot be returned. Clearance items are final sale. To start a return, email completehealthfwsw@gmail.com with your name, product details, and purchase date. If something arrives damaged, snap a photo and reach out right away and we'll get it sorted.
