Health by Principle supplements are formulated with high-quality ingredients and designed to support overall wellness. While our products are well-tolerated by most people, individual responses may vary. Some individuals may experience mild digestive discomfort or sensitivity to certain ingredients. If you have any concerns or underlying health conditions, we recommend consulting with a healthcare professional before starting any new supplement. Please note that our products are not evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease.

Yes! All of our supplements are designed to be taken together, as long as you follow the recommended directions on the label. However, if you are taking prescription medications—especially for conditions like high blood pressure, blood sugar regulation, —we recommend consulting with your doctor before adding any new supplements to your routine. Please note that our products are not evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease.

We follow best GMP (Good Manufacturing Practice) standards, which is why our supplements are labeled with a two-year expiration date to ensure optimal potency. While vitamins like D3 may gradually lose effectiveness over time, minerals such as magnesium and electrolytes do not technically expire. However, for the best results, we recommend using all supplements within the indicated timeframe to ensure you’re getting the full intended benefits.

All of our products are manufactured with all natural materials here in sunny California. All products are designed, selected, approved and produced in a GMP, NSF, USDA Organic, Organic Process Food Licensed, and NSF Sport Certified science lab in the U.S.A. For our Health by Principle UK store, all products are manufactured in a GMP certified lab in the UK.
