Why This Supplement
Why This Supplement
Crash-Free Energy
ZumXR extended-release caffeine pairs with caffeine anhydrous for immediate onset plus a gradual taper over hours, eliminating the spike-and-crash pattern of single-source formulas.
Deep, Calm Focus
Alpha-GPC fuels acetylcholine while Huperzine A slows its breakdown, creating a sustained focus stack. L-Theanine smooths the experience so clarity stays calm, not anxious.
Mental Drive
L-Tyrosine replenishes dopamine and norepinephrine under cognitive load, maintaining motivation and stress resilience through demanding work or study sessions.
Hydration Support
Coconut water powder provides natural potassium, magnesium, and sodium electrolytes to support cognitive function and hydration for sustained mental clarity.

Know before you scoop!
Still not sure? Our team offers free consultations at both Fort Wayne locations.
How should I store my supplements?
+
Store in a cool, dry place away from direct sunlight. Keep the lid tightly sealed to prevent moisture exposure. Some probiotics and specific formulas may require refrigeration — check the label for storage instructions.
Can I take multiple supplements together?
+
Most supplements can be stacked safely, but timing matters. Our staff offers free consultations at all three locations to help you build a personalized stack that works with your goals and any medications you're currently taking.
How long until I see results?
+
Results vary by product and individual. Some supplements like pre-workouts and energy formulas work immediately, while vitamins, minerals, and adaptogens typically need 2-4 weeks of consistent use to show noticeable benefits.
Are your supplements safe for women?
+
Most of our supplements are formulated for both men and women. However, some hormone-support products are gender-specific. Check the product label or ask our team for guidance. Pregnant or nursing women should consult a healthcare provider before taking any supplement.
Do you offer free consultations?
+
Yes! Every Complete Health location offers free one-on-one consultations. Our staff lives and breathes fitness and nutrition — they'll help you find the right products for your specific goals, body type, and budget. No appointment needed.
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.
