Good

I bought this for a family member who has hypertension. Olive leaf extract is known to lower blood pressure naturally. I haven't tried this myself, but I've seen good results according to my family. The bottle is medium sized, and will finish quickly if you drink it every day.

A fine product of its type
Verified purchase
Comvita is a very good tasting and soothing product. I usually save it for colds and flu. I keep it in the frig when open and its freshness can be maintained for long periods of time. The generous size makes it a further good purchase. Convenient, good tasting, and stays fresh in the frig. A winner for its type of product. cheers

I placed my order quickly and efficiently. I’m a loyal customer of this site and I’m now waiting for my package. However, it would be nice if iHerb also offered some product samples.

Amazing product
Verified purchase
Sad to say I find the taste disgusting, but my cholesterol reading has dropped from 6.9 to 3.9 in less than three months. I have altered my diet too, but was assured by the pharmacist I was unlikely to reduce my reading by more than 20% without statins. So glad I didn’t listen to him!! I was recommended this product by a retired nurse.

Great find
Verified purchase
Quality ingredients. A big size bottle that will lat for a long time. Dosage is 1 tablespoon a day for adults. I only take it and give it to my children when I feel I’m coming down with something and continue until the symptoms have disappeared. I usually take it with oil of oregano and honestly, this stuff works like magic.

Amazing for your Health!
Verified purchase
I’ve been taking olive leaf extract for years.. The Comvita brand is excellent quality and very potent. Olive leaf extract is good for so many things. To name a few, viruses, antibacterial, antimicrobial, the flu, pneumonia , colds stomach bugs, parasites, fungus, skin issues., etc. I’ve read that it dissolves warts. It really is amazing stuff! Highly recommend!

Liquid Gold!
Verified purchase
After trying Olive leaf supplements, I wanted to switch to a potent liquid extract for added benefits. Dosage is easy to take and I take one teaspoon daily. It has amazing cardiovascular benefits and also helps with overall well being. My allergies have significantly lowered and I also noticed a boost in my immunity. I will continue to use it daily.

I’ve tried few olive leaf extract products, and this is by far the best quality I’ve come across. It offers many great health benefits and has been particularly helpful in supporting my overall wellness. I’ve noticed a positive impact on maintaining healthy glucose levels, and it also seems to help with sinus issues. Highly recommend it for anyone looking to incorporate a natural supplement into their routine!

Excellent product
Verified purchase
I have been taking olive leaf extract for many years for my health and I've always taken in a pill form and I decided I want to get rid of that capsule because I find I'm having a hard time swallowing it so I decided to just get pure olive leaf extract and put it right in water and drink it down and it seems fine but I believe in this olive leaf extract I think it's been keeping my immune system healthy. This is a pretty good product.
