absolutely love it 10 out of 10 and I work at a vitamin store I've been trying to get this in there but they haven't yet and I still recommend it to customers because when something is this good you have to let the world know!!! You cannot let the triquetra black seed oil quality be a secret!!!

There's no problem with the product, although it is strong.

They worked really well for me, but the issue is that they might have affected my chemotherapy treatment. The product is very good; it made me feel great and I regained a lot of strength, but that's the only problem. I'll try another product; this is trial and error.

Can’t live without it!

Black seed oil, and specifically Triquetra’s capsules because they make it palatable, is a non-negotiable supplement in my day. Results are noticed quickly: no more pain in fingers, wrists, hands! Miraculous!

Healthy Choices

Taking care of your health is one of the best investments you can make in yourself. I enjoy choosing products that help optimize my overall health because every healthy choice contributes to a better quality of life. What I appreciate most is having the flexibility to choose between liquid and pill options, making it easier to find what works best for my lifestyle and daily routine.
While no supplement can replace a balanced diet, exercise, and regular medical care, quality health products can be a helpful addition to a healthy lifestyle. For me, having convenient options makes it easier to stay consistent and focused on my wellness goals. Feeling your best starts with making intentional choices, and prioritizing your health today can have lasting benefits for tomorrow. Black seed extract has me feeling good, that’s for sure!

Unexpected benefit

I purchased the black seed extract to help with joint inflammation. To my surprise, it help with my acid reflux. No more Prilosec for me. As other reviews have stated, constipation can happen.

Cannot take diatomaceous earth

I didn't realize the capsules contained diatomaceous earth (DE). I can't take DE. It causes horrible things to happen in my body. I wasted my money. The product is sitting in my closet.

Batch Variation is extreme

I have been taking your products for a long time, and my entire family uses your products (and will continue to do so). We purchase directly from you and have many products on Subscribe & Save on Amazon. For this particular product, which I have been taking for over a year, this last batch (purchased from Amazon and directly from you) was very different. It had a very chemical smell and taste, and the product makes me feel different than prior batches. While I will continue to take this product due to your vigorous testing and quality practices, this last version is not even close to prior ones.

The indigestion has made these impossible to take

I should have reviewed the side effects more clearly before purchasing this supplement. I've had noon stop gastric problems including commit into my esophagus. These are NOT for me.

Formula Change

These used to be AMAZING. However the most recent batch is TOTALLY DIFFERENT than the product they used to sell. It smells like iodine and other chemicals and not at all like the spicey black seed powder that I had been used to. Unfortunately I will not repurchase until the formulation returns to the original.
