What is Garlic?

Garlic is a Botanical supplement available in 2 forms.

Not all forms of Garlic are equal. The form you choose determines how much Garlic actually reaches your tissues, and the difference between the best and worst forms can be substantial. This garlic extract standardized to 1% allicin-yield provides consistent potency of the primary bioactive organosulfur compound formed when alliin and alliinase interact. Research supports allicin-standardized garlic for promoting healthy cardiovascular function, immune response, and antimicrobial defense more reliably than aged garlic or non-standardized garlic powders.

Forms of Garlic Compared

Garlic (Allium sativum) Bulb Extract (1% Allicin) Preferred (Preferred Form) has a bioavailability rating of good (S2). Typical dose range: not yet documented in our database.

Garlic (Customer Choice) has a bioavailability rating of low (S4 — basic). Typical dose range: not yet documented in our database.

What the Research Shows

Garlic extract standardized to 1% allicin provides the primary bioactive sulfur compound responsible for cardiovascular benefits. Research demonstrates support for healthy blood pressure, lipid profiles, and immune function. Allicin-standardized extracts provide more consistent dosing than aged garlic or raw garlic preparations.

AGE produces stable S-allylcysteine with ~98% oral bioavailability vs allicin instability PMID: 11238803
S-allylcysteine from AGE at significantly higher plasma levels than allicin from raw garlic PMID: 22129334
Aging converts unstable allicin to stable S-allylcysteine; half-life ~10-14h PMID: 24461566

How to Choose the Right Form

Garlic (Allium sativum) Bulb Extract (1% Allicin) is classified as Preferred Form by FormulaForge — our top recommendation for Garlic. It carries a bioavailability rating of good (S2), meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.
