Frequently Asked Questions

Is aged black garlic better than regular garlic supplements?

For supplementation purposes, yes. The aging/fermentation process converts unstable allicin (the compound in raw garlic) into S-allyl cysteine (SAC), which is 98% bioavailable and stable. Raw garlic supplements contain allicin that degrades quickly in the GI tract. Aged garlic also eliminates the harsh GI side effects and strong odor of raw garlic supplements, improving compliance.

Can aged garlic extract lower blood pressure?

Yes. Multiple randomized controlled trials and meta-analyses show that aged garlic extract reduces systolic blood pressure by approximately 8-10 mmHg in hypertensive individuals at doses of 600-1200mg daily. This effect is clinically significant and comparable to some first-line blood pressure medications. However, it should not replace prescribed antihypertensive medications without physician guidance.

What is S-allyl cysteine (SAC) and why does it matter?

S-allyl cysteine (SAC) is the primary bioactive compound in aged garlic that forms during the fermentation process. Unlike allicin in raw garlic (which is unstable and poorly absorbed), SAC has 98% oral bioavailability, is water-soluble, and is standardized in quality aged garlic extract products. SAC is responsible for many of garlic's cardiovascular and antioxidant benefits.
