Frequently Asked Questions
Absolutely. CoreStrength is made with 100% natural ingredients and is manufactured in the USA in an FDA-registered facility that follows Good Manufacturing Practices (GMP). However, as with any supplement, it’s always wise to consult your healthcare provider before starting.
Many CoreStrength users start noticing improvements in mobility and comfort within the first 2–3 weeks, but for optimal joint and bone support, we recommend using it consistently for at least 3 months. Remember — rebuilding strength and flexibility takes time, and consistency is key.
No drastic lifestyle changes are necessary. CoreStrength is designed to naturally support your bones and joints, helping you move with ease and confidence. However, pairing it with light activity, good hydration, and a balanced diet can help you see even faster improvements.
Yes, CoreStrength can generally be taken alongside other supplements. Just make sure you’re not doubling up on vitamins D, K, or calcium from multiple products unless advised by your healthcare provider.
For the best experience and results, we recommend starting with a 3 or 6-month supply. This ensures your body has enough time to fully absorb the nutrients and strengthen your joints and bones from within.
We believe in the power of CoreStrength — but if you’re not completely satisfied, we offer a 90-Day Money-Back Guarantee. Simply reach out to our customer service team, and we’ll process your refund—no questions asked.
Orders are processed within 2–3 days. For customers in the U.S., delivery typically takes 5–7 business days. International orders may take 10–12 days depending on customs procedures.
For optimal results, take one capsule daily with a glass of water, ideally in the morning with breakfast. Consistency is key to rebuilding strong bones and flexible joints.
