Product Overview 

Cerium (Ce) is one of the most abundant and cheap rare earth elements. Due to its unique 4f electronic structure, CE has been widely used in many fields such as alloy, fluorescence, magnetism and catalysis in recent years. Accordingly, its cerium oxide (light yellow powder) has also attracted great attention. The CeO2 crystal structure is cubic fluorite structure, in which the metal cation (Ce4+) is arranged according to the face-centered cubic lattice, while the anion (O2-) is located in the tetrahedron center. Ce elements usually contain two oxidation states, Ce4+ and Ce3+. When the temperature is very high or in a reducing environment, it can be reduced to CeO2-x (0<x¡ãC.5), resulting in the two valence states can be quickly and reversibly converted to each other, so oxygen vacancy defects are very easy to appear in the lattice of CeO2-x. Due to their inherent oxide defects and excellent REDOX properties and oxygen storage capacity, CeO2 nanoparticles are commonly used as heterogeneous catalysts or active oxide carriers of catalysts.

Mesoporous Ceria Nanoparticles (CeO¡ãCNPs) are nanomaterials with mesoporous structures with pore sizes between 2 and 6 nm. The mesoporous structure provides a large specific surface area and more active sites for various reactions.

Seems good.
This seems to be good quality and they build trust with the third party testing. The bottle arrives safety sealed for assurance. The blend is good; especially with the BioPerine for easier absorption. The capsules have not taste and are easy to swallow. So far, I'm quite pleased. The quality and price seems fair compared with other offerings. I have no negatives to note.

Useful supplement
It is difficult to measure the efficacy of these supplements. With that said, I like taking some daily Curcumin as this falls into the category of "Won't hurt, might help". The ingredient has been used for ages in different cultures, and promises a long lists of potential benefits. One would have to eat large amounts of Turmeric to get the benefits of what is concentrated in this pill, along with some black pepper for better absorption. The suggested use is 3 capsules per day, so the 180 capsules will cover 60 days /2 months. This somewhat distributes the cost of the product. There are the usual trust-increasing stamps on the label, including a Made in the USA one. The label is easy to read and attractive, and the bottle is protected by anti-tampering seals and plastic.

After ***TOO MUCH*** Research
After ***TOO MUCH*** Research The Amazon ad for this product is so ambiguous that I thought I should do some research before taking this supplement. After AN HOUR AND A HALF of googling, for information I've decided to give this 2 stars. Initially, I was thinking 4 stars (that would have been 5 stars, but I'm not happy about all the googling I had to do about the ingredients), but I decided to lower it because after a great deal of research, I'm still not sure if I should take the label's full recommended dosage, or something lower. But I'm going to start here with the positive: The main things that convinced me to order it it is that it's made in the USA in an FDA registered facility that is GMP certified. and it's 3rd party lab tested. But even though that put my mind to rest about production, the ingredient list is ambiguous, and since there's no Medical Recommended Dosage, I want to know what a safe amount to take is. The ingredients and amount of the supplement provided are MUCH too ambiguous label says that 3 caps provides 1800 mg of organic turmeric (cucurma longa root), and 150 mg of turmeric 95% curcuminoids (cucurma longa root). So what's the difference between these 2 ingredients? And what does it mean, anyway? I read down the entire page, and at the bottom the Product Description notes that "each serving delivers 1950mg of turmeric curcumin, standardized to 95% curcuminoids". But that doesn't explain much. Does that mean that the entire 1950 mg is curcuminoids? Why are the amounts listed sepaerately in the ingredient list? I googled for information about the different ingredients, but I'm not sure how to interpret it. Here's what I found: * A page on the NIC (official US government site) notes that "curcumin is a major component of turmeric, and the activities of turmeric are commonly attributed to curcuminoids (curcumin and closely related substances)". * Another NIC page, noted "In Curcuma longa, crude extract curcuminoid makes up 1–6% of turmeric by weight, distributed in 60–70% curcumin...whereas commercially available curcumin contains about 77% in curcuminoids." * On a page for a vitamin company (not the manufacturer/distributer for this particular product), I read "Curcumin 95 is a botanical extract from turmeric root spice. Curcumin 95 contains 95% curcuminoids." But the label is so confusing. Does that mean that 95% of the entire "1950mg of turmeric curcumin, standardized to 95% curcuminoids" is the amount in 3 caps? Or is it 95% of the 150 mg of the turmeric 95% curcuminoids, listed as an ingredient? And what's a safe amounts to take. The results vary a lot. A page on the Arthritis Foundation site says, "In one small randomized controlled trial, twice daily doses of either 250 or 500 mg of curcumin were compared to placebo. Both doses significantly outperformed placebo on all measures." This site also recommends taking a supplement that includes black pepper (as this does) "for better bioavailability".

Turmeric curcumin & black pepper
These capsules come in a freshness and safety sealed bottle. They’re pretty large, but the vegan cellulose capsules swallow easily with a little water. A serving is 3 capsules, You really smell the black pepper extract and turmeric when you open the bottle. The suggested use is to take them 20-30 minutes before a meal.
