GOOD TO KNOW

Questions, answered clearly.

Helpful guidance for comparing formulas, reading labels, and finding Probase Nutrition wherever you live.

Contact our team
How do I choose the right supplement?

Begin with one clear wellness goal. Compare the active ingredient, amount per serving, suggested use, other ingredients, and any allergen details on the product label. If you take medication, have a medical condition, or are pregnant or nursing, ask a qualified healthcare professional before use.

What does third-party tested mean?

It means testing is performed by an independent laboratory rather than only by the brand or manufacturer. The exact specifications can vary by product, so review the product page or contact us if you need product-specific quality information.

Can I take more than one Probase product?

Products can differ in ingredients and serving directions. Check each Supplement Facts panel to avoid unintended overlap and ask a healthcare professional to review your complete routine when you are unsure.

Do all Probase products have the same serving size or format?

No. The collection includes capsules, powders, tablets, softgels, and liquid or liposomal formats. Serving size and directions are specific to each product, so always follow its label.

Can I buy Probase Nutrition outside the United States?

Yes. Probase Nutrition products are available to shoppers in more than 180 countries through iHerb. Availability, delivery times, duties, and local restrictions can vary by destination.

Where else can I find Probase Nutrition?

You can shop the available selection on the Probase Nutrition website and through participating retailer pages on Amazon, iHerb, Walmart, and Target. Product assortment can vary by retailer.
