Use Iso-Rich Soy as a dietary supplement to increase your intake of protein, isoflavones.

Soy isoflavones, along with other naturally occurring soy phytonutrients, have been shown in scientific studies to have many health benefits, including maintaining healthy cells, promoting normal cardiovascular function, supporting bone health and assisting estrogen balance.

Jarrow Formulas Iso-Rich Soy contains water-extracted, Non-GMO (Genetically Modified Organisms) soy protein isolate.

  • Consistent isoflavone level. Each serving guarantees a minimum of 56 mg of naturally occurring isoflavones, consisting of genistin/genistein, daidzin/daidzein and glycitin/glycitein. The isoflavone level in Iso-Rich Soy reflects the daily dietary intake of isoflavones in Asian countries such as Japan.
  • Water extraction of soy protein preserves naturally occurring isoflavones and saponins.
  • Saponins, another naturally occurring group of phytonutrients in soy, have been shown in scientific studies to enhance the body's defense mechanisms.
  • Health Claim: Consumption of 25 grams of soy protein a day, as a part of a diet low in saturated fat and cholesterol, may reduce the risk of heart disease. A serving of Jarrow Formulas Iso-Rich Soy provides 25 grams of soy protein.

Iso-Rich Soy is a complete source of essential amino acids and meets or exceeds the daily "Amino Acid Requirement Patterns" for adults measured by PDCAAS (recommended by the Food and Nutrition Board, 1989).

An excellent product that lowers cholesterol. It may also prevent osteoporosis

Soy may lower blood cholesterol and may also prevent osteoporosis (bone loss). This form can be easy taken with milk.

Jarrow Formulas, Iso-Rich Soy, 14 oz (400 g) Powder

Posted by FEED-ME-MORE on Aug 13, 2013

3 stars only because of the best available price for soy protein (enough protein in grams) in iherb.com But mixability, dissolubility and the taste are just awful. Taste reminds me of glue. I don't know how can it be like this, as I loved very much similar soy protein from Now Foods. So, I hardly would by from Jarrow Formulas again, though the price is extremely good. But I guess you get what you pay ? Maybe not always, but in this case it is true.

It was the perfect protein powder but the formula has changed.

Posted by Reviewer2905225 on Oct 02, 2012

This was perfect and I used it for years. In my recent shipment was a new formula and this formula is just horrible. It is really foamy, tastes like whey protein and the powder is so fine it flies all over the place. Very messy. I am so distressed over this because I rely on this protein powder, which I said, was formally perfect. I returned 7 containers to iherb. I called Jarrow and was told that they did have a new distributor and have gotten complaints like mine but that it would be a while before this would be changed. I know how to find a new protein poweder:( Ft. Lauderdale, Florida
