Great value for a great supplement
Verified purchase
Nutricost Olive Leaf Extract Capsules are a great addition to my medicine cabinet. The quality of the olive leaf extract with its legendary health properties is impressive. The dosage and capsule size are just right, making it easy to take. Plus, it has a neutral taste and I see its benefits as a natural alternative to antibiotics.

My first impression was somewhere between “nice enough” and “we’ll see.” I’ve been disappointed by beautifully presented products before, so I wasn’t handing out compliments on day one. After several weeks, though, the practical side has held up exceptionally well and I haven’t discovered any irritating quirks. My opinion improved slowly, which somehow makes it feel more trustworthy.

Reliable Immune Support with Noticeable Benefits
Verified purchase
Nutricost Olive Leaf Extract has been a great addition to my wellness routine. The 750 mg dose feels effective, and after taking it consistently, I’ve noticed better immune resilience and fewer seasonal issues. The capsules are easy to swallow and don’t cause any stomach discomfort. I appreciate the clean formula and the overall sense of well-being it supports. It’s a simple, dependable supplement that I’m glad to have in my daily regimen.

This is one of the best vitamin C supplements I've tried! The absorption is noticeably better thanks to the liposomal form, and it's very gentle on the stomach—no discomfort or acidity at all. I felt a clear boost in my immunity after just a few days of use. The antioxidant benefits are real, and I love that it's high quality with clean ingredients. The taste is surprisingly pleasant, and the individual packets are super convenient for travel. Great mg dosage and well thought-out package size. Highly recommend!|

Great for immune boost.
Verified purchase
I’ve been reading up on the benefits of olive leaf extract and was really happy to find this product here. My teens and I have been taking it for the past few weeks now and it’s been really effective for keeping us healthy considering we all have such busy lifestyles with eating out regularly and not really having the best diet.

Olive leaf is great stuff all around.
Verified purchase
I purchased a bottle of Olive Leaf and took them one day when I started to feel the flu coming on. I was cold, achy, had a slight fever and just felt blah. I took 2 olive leaf capsules and within a half hour I felt better. I have read Olive leaf Extract contains oleuropein which is a potent antioxidant and this brand of OLE contains 20% oleuropein. Other brands I looked through contained 6%-15% and this was 20%. Nature's antibiotic right here
