Frequently Asked Questions

Why is Raw ACV with "The Mother" Best?

Raw, unfiltered ACV contains the “mother,” a cloudy strand of proteins, enzymes, and beneficial bacteria. This is the source of many of its health benefits. Filtered, pasteurized (clear) versions lack the mother and are less potent. Raw ACV lasts indefinitely when stored away from light and heat.

How Does ACV Affect pH Balance?

Though it is acidic (pH ~3), ACV has an alkalizing effect after it is metabolized by the body. It supports this balance by improving digestion and mineral absorption, which helps reduce inflammation and infection risk.

Are ACV Capsules Effective?

ACV pills are a convenient option if you can't stand the taste. While not identical in potency to the liquid, many people still find they offer noticeable benefits.

Is ACV Safe for Pets?

Yes, ACV is widely used by pet owners for flea control (in a spray), bladder infections, and skin issues (like itchy paws). Always use proper, high-dilution rates based on your pet's size and condition.

Where Can I Buy Organic ACV?

Look for raw, organic ACV with “the mother” in most grocery stores. If it's unavailable locally, you can order it from Amazon or check the Where to Buy ACV guide.
