does this coq 10 originate from japan

Hi Virginia! One of NOW's Licensed Nutritionist & Registered Dietitians in the Product Info Dept. was able to answer your question:The CoQ10 raw material is China sourced. We test for heavy metals, microbial contaminants, identity, and purity to ensure highest quality.It is encapsulated here in US and bottled and labeled here in our Bloomingdale USA facility. The most important considerations are that our ingredients are safe, meet specifications, and are not adulterated. Although today the focus is on specific ingredients from China, problems can arise even with U.S. produced ingredients. The issue is thus not the country of origin, but the safety, quality and integrity of the entire supply. Bad ingredients can and do come from anywhere. The only sure solution is to have a strict program in place to test ingredients before they are used in foods and supplements. At NOW Foods we have in-house state-of-the-art chemical and microbiology testing facilities. We are on top of ingredient issues facing our industry and focus our testing on those issues in addition to the day-to-day product testing required by our GMP certification. Our testing is based on USP, AOAC, and other official or published methods. To test for Melamine for example we use a FCC HPLC or FDA GC Developmental Melamine Quantification method. We audit our suppliers, which includes visiting facilities where ingredients are processed to examine the protocols for ensuring safety and quality.Information in this response refers to product labeled for sale in the USA unless otherwise indicated.

Ubiquinol or Uniquinone?

Both forms of CoQ10 (uniquinone and ubiquinol) occur in the human body. According to the NatureMade website, it doesn't matter which you take: "Regardless of what form of CoQ10 you take as a supplement, the body is able to convert the consumed form to the other form as needed. In other words, if you take a reduced CoQ10 supplement (ubiquinol), the body can convert the reduced CoQ10 (ubiquinol) to the oxidized CoQ10 (ubiquinone) and vice versa. This conversion takes place to maintain a state of equilibrium between reduced CoQ10 (ubiquinol) and oxidized CoQ10 (ubiquinone)." NOW WHAT I'm WONDERING IS WHY THANH thinks one is for younger people?

I've read carefully on "Coq10 100mg, 180 Vcaps", but nowhere can I find, whether or not there is liquid or dry stuff in the capsules - help! & Thanks

Most NOW capsules have dry contents as does the CoQ10.

Not sure to what certification you are referring. Hopefully this will help you. NOW® CoQ10 is Pharmaceutical Grade. NOW® CoQ10 products contain only the natural, all-trans form of CoQ10 produced by fermentation. It is GMP Certified. GMP refers to the Good Manufacturing Practice regulations enforced by the US Food and Drug Administration (FDA). It provides for systems that assure proper design, monitoring, and control of manufacturing processes and facilities. In addition, GMPs are guidelines that provide a system of processes, procedures and documentation to assure a product has the identity, strength, composition, quality and purity that appear on its label.
