If you want the allicin approach rather than aged extract, the coating is the whole ballgame. Allicin precursors (alliin plus the enzyme alliinase) are destroyed by stomach acid, so an uncoated garlic tablet delivers far less than its label claims. NOW's Garlic 5000 uses an enteric coating designed to survive the stomach and release in the upper intestine, where conversion to allicin can actually happen. At around $11 and backed by NOW's UL/NSF-registered GMP manufacturing, it is the best-value credible entry in this category. Just keep expectations honest: a high allicin-yield number on the label does not linearly translate into bigger blood-pressure drops.

Read the complete Garlic guide →Enteric-coated tablet built to protect the alliin/alliinase system from gastric acid so allicin forms in the upper intestine. Sound mechanism, though real-world allicin release from any enteric tablet is variable and hard to verify per batch.
500 mg garlic standardized to a minimum 5000 mcg allicin yield — a concrete, high potency spec that lands within trial-relevant ranges. 'Yield' is a potential figure, not a guaranteed delivered dose, which is the usual caveat.
Made in a NOW UL/NSF-registered GMP facility with Non-GMO verification. NOW's in-house testing program is well regarded, though this SKU does not carry a per-product NSF Certified for Sport-style seal.
Enteric coating reduces garlic breath and reflux versus raw powder, though allicin-route products still cause more odor than aged extract for some users. Standard antiplatelet caution applies.
At roughly $11 for 90 tablets, this is the cheapest credible enteric-allicin option here — excellent cost per effective day for the mechanism.
“Enteric coating improves allicin delivery”
Dissolution studies (Lawson & Wang) show enteric coating protects allicin precursors from acid, but real-world allicin release varies widely between products and even batches, so the mechanism is sound but delivery is not guaranteed.
“The 5000 mcg allicin yield produces proportionally larger heart benefits”
Trials do not show a linear dose-response between labeled allicin yield and blood-pressure reduction; garlic's BP effect plateaus around the same modest ~5 mmHg regardless of headline allicin numbers.
“It reduces garlic odor versus raw garlic”
The enteric coating delays release past the stomach, cutting immediate breath odor, but allicin-route products still produce more sulfur odor for many users than aged garlic extract.
'5000 mcg allicin yield' means the tablet can generate that much allicin under ideal lab conditions. Actual amount released depends on coating integrity, transit time, and enzyme survival — which is exactly why aged extract sidesteps the problem by standardizing a stable end-compound instead.
Among products offering a genuine enteric coating and a standardized allicin spec, this is the cheapest. If you have decided you want the allicin route rather than AGE, there is little reason to pay more unless you specifically need a per-product third-party seal.
NOW Garlic 5000 is what to buy if you want the allicin mechanism without overpaying. The coating and standardization are legitimate and the GMP oversight is real. It ranks just below Kyolic only because aged extract has the stronger direct trial record — but on price-to-credibility, nothing beats it.
