Question: Where Are your products manufactured?

Answer: Zahlers products are manufactured exclusively in the USA in state of the art, third party cGMP certified facilities, which meet our high quality standards and comply with all safety regulations.

Question: What is a Daily Value?

Answer: The Daily Value is the amount of a nutrient the body needs based on a 2000-calorie diet for an average sized person. There are two standards that are referenced as follows: 1. Daily Reference Values 2. Reference Daily Intakes (RDIs), which replaced the term “U.S. RDA” (the values determined by FDA and used on food labels, taken from the “RDAs” which are values determined by the National Academy of Sciences for various populations groups). The Daily Value (or a RDA's) is the amount of a nutrient that will satisfy the minimum basic requirement for function and avert a disease of deficiency (the Daily Values, are the values that will be seen on the labels). However, these values were never intended to imply a safe maximum amount of a vitamin you can take, amounts that can foster maximum vitality, or amounts that may give therapeutic benefits. While RDI levels may avert the body from becoming deficient they do not factor in depleted or deficient states that may lead to disease. The RDA should be viewed as a nutritional poverty line. It is unwise to consume less but it is not a guidance for maximum health.

Question: What is the source of the gelatin you use in your softgels?

Answer: The gelatin that we use in our softgels vary per product. You can find that information on the label listed under other ingredients. As a rule we always use gelatin that is EDQM (European Directive on Quality of Medicines) compliant, poses no risk of disease transfer (TSE or BSE), and is always certified Kosher and never sourced from porcine products.

Question: Are dietary supplements regulated under the FDA?

Answer: Dietary Supplements are regulated under the FDA (Food and Drug Administration) through 21 CFR Part 111 of the Food Drug and Cosmetic Code and specifically DSHEA (the Dietary Supplement Health & Education Act of 1994). All aspects of what ingredients can be used, the manufacturing practices and facilities (including the qualifications of the individuals working in them) and what can be claimed on product labels. Additionally, each state has both an attorney general and a state department of health that has jurisdiction on supplements. The FTC (Federal Trade Commission) can exercise enforcement powers over Supplements and the department of commerce and department of trade can exercise enforcement on interstate and international commerce. Finally, the courts through class action have been a significant regulator of supplements.

Question: Are your products substantiated by scientific studies or research and is this part of your product development process?

Answer: Yes! Each time we set out to create a new formula, the process begins with an extensive review of the available clinical research. It takes painstaking meticulous research and a solid understanding of the human body to create an effective formula. The payoff, of course, is the result. Zahler supplements use clinically proven ingredients and doses of these ingredients that are substantiated by either clinical studies or long traditions in botanical medicine. Our Formulas are the product of hard data, typically published in peer reviewed journals and an impressive compendium of real world evidence.

Question: Is it safe to take your product if it has expired?

Answer: Expiry dates are dates determined by either stability study or estimates based on data that the product will meet label claim and not be harmful. If a product is past its expiration date, it is not necessarily likely to be harmful. It is, however, likely that the potency of the nutrients will be diminished and there is a chance of increased microbial contamination or breakdown by products. In the case of products that contain lipids there is a chance that oxidation has diminished the quality of the product and that it may contain rancid fats.

Question: Can I open up the capsules of your products and mix them into juice, yogurt etc.?

Answer: Yes that’s totally fine. The quality of the supplement will not be altered if you spill out the powdery contents into juice or yogurt. However, be sure not to mix it into anything warm or hot, as that will reduce or destroy the potency. The opened capsules and food product should be consumed immediately as the nutrients and herbs may interact with acids or other compounds in the food.

Question: Are all your products Kosher?

Answer: Yes, every single of our products are 100% Kosher. Our entire line is manufactured under the strict supervision of Rabbi Sh. Stern of Debreczin and the Orthodox Union. Rather than being an afterthought, Kashrus is a primary consideration that factors into the research and development phases of every Zahler product.

Question: How do I as a consumer know that the products that I purchase contain the ingredients that are on the label and are at full potency?

Answer: This is a key concern for us at Advanced Nutrition by Zahler; and we are committed to producing quality products. We have a strict quality control process that meets or exceeds the rigorous quality standards of the U. S. Food and Drug Administration We only have our products manufactured in facilities that are compliant with all regulations and that have taken the extra step to invite third party auditors into their facility to assure compliance. We guarantee the potency of all labeled ingredients as long as the product has been properly stored and is within its shelf life.

Question: How can I be sure that the ingredients you use in your products are pure & safe?

Answer: We only source ingredients that have been tested using validated methods for identity, potency, and purity. This is a cornerstone of cGMP compliance and we never “just trust a vendor Certificate of Analysis”. After identity and potency is confirmed, we test for toxic metals such as lead, mercury, cadmium and arsenic, microbial contaminants and likely adulterants. Every product we develop and produce is subjected to rigorous testing, and is manufactured and bottled (or blister packed) in a state-of-the-art GMP certified facility. When it comes to nutrition, insist on the purest. We do.

What is the difference between the folate (Quatrefolic 5-methyltetrahydrofolic) in Prenatal+ DHA versus standard folic acid found in most prenatal supplements?

The naturally occurring, metabolically active form of folate (Quatrefolic 5-methyltetrahydrofolic) found in Prenatal +DHA is the most stable and bioactive form of folate. Folate (Quatrefolic 5-methyltetrahydrofolic) is body ready, which means it requires no complex conversion and eliminates the risk of un-metabolized folic acid. This naturally occurring form of folate is required by a large percentage of women due to an MTFHR gene mutation, as these women either lack the enzymes needed to receive any benefit from synthetic folic acid, or cannot fully process synthetic folic acid at RDA or higher dose levels.

Question: What's the difference between Omega 3 Platinum and Omega 3 Platinum+D?


Being that many people do not get adequate fatty acids from their diets, as well as Vitamin D, which are both so vital for our health, we thought a combination of the two will allow people to benefit from both simultaneously.
