Is there a chart giving an idea as to how many pills would be equivalent to, say, 4oz of beef liver? Thanks for any help.

Great question... 1 serving of Grassfed Beef Liver (6 capsules) is equivalent to 1oz of raw undefatted beef liver. With that said, 4 servings (24 capsules) of Grassfed Beef Liver is equivalent to 4oz of raw beef liver. Nutrition authorities like Chris Masterjohn (of Mastering Nutrition) and the WAPF recommend 1 to 2 servings of liver per week (or) a total of 6 to 8oz per week. To achieve this amount with Grassfed Beef Liver, simply consume the recommended daily serving of 6 capsules per day. We hope this helps... be sure to let us know if you have any other questions.

how much heme iron is contained per serving?

One serving of our Grassfed Beef Liver provides approximately 2mgs of glandular derived heme iron along with many other iron regulating nutrients (B12, zinc, copper, etc) that go into iron status. Grass fed liver fills nutrition gaps more completely than any other food... but if it's iron you're after, you may want to look at Grass Fed Beef Spleen which provides 5 X's more heme iron than liver. Spleen is the richest source of heme iron that exists in harmony with nature.Since you are asking about heme iron, it appears that you are aware that animal organs and meats contain a source of iron bound to hemoglobin (heme iron) of which up to 33% is absorbed compared to non-heme iron which can have as little as 2% absorption... 2mgs per serving may not sound like a whole lot but a little heme iron, along with all the other nutrients from liver that support endogenous iron product, can make a substantial difference in managing your iron status.If you have any other questions, feel free to ask here or send us an email. We love hearing from our customers!

A Is there any worry about high Iron from taking the desiccated beef liver?

Organs and glands are nutrient dense, whole foods. The recommended serving (6 capsules) is equivalent to about one ounce of fresh, raw organs / glands that you’d get from your local farmer (or) butcher. The amount of heme iron that one would expect in this serving size is approximately 2 mg. A moderate amount of liver will almost always confer more benefit than potential harm from too much iron. Nutrition authority Chris Masterjohn, PhD has a great podcast on this topic entitled "Why You Need to Manage Your Iron Status and How to Do It." The take home message is that liver is too nourishing, and too good for our biology, to eliminate it from our diets... instead, eat the liver and reduce some other iron rich foods here and there if you are "concerned" with iron overload. He even goes so far as to suggest combining some dairy (or calcium) with the liver to lessen the bio-availability of the iron if too much iron is a concern for an individual. If you're still concerned, I'd suggest listening to his podcast. You can skip right to the good stuff by fast forwarding to 01:21:03. I hope this helps!

How much vitamin A does this contain?

There is approximately 5,000 IUs of Vitamin A per serving. The Vitamin A contained in beef liver is the real deal Vitamin A (retinol) in contrast to the beta carotene version that poorly converts.Many people believe that they can get enough vitamin A from their fruits and veggies—simply put, they can't! Fruits and vegetables are high in a family of phytonutrients called carotenoids (e.g. beta-carotene). Because of this, many people (and websites alike), believe that these foods provide vitamin A; however, they do not. The body must convert these compounds into vitamin A; but in humans, this process is inefficient and hardly takes place. The data shows that only three percent or less of carotenoids from plant foods are absorbed. In contrast, eighty percent or more of preformed vitamin A from animal sources (i.e. liver) is absorbed. If you're not consuming liver one to two times per week, you're not getting adequate vitamin A. If you're not getting adequate vitamin A, you're likely not optimizing health metrics (e.g. immune function, cartilage, ligaments, tendons, gums). The simple solution is to eat liver twice a week. If you're just not going to do it, consider a high quality liver supplement.
