Understanding the Myths of Soy Protein Supplements

Soy is a part of the pea family and has been linked with several health controversies over the years causing supplement companies to wonder whether they should or should not produce a soy-based supplement. Recognizing the facts and debunking some of the myths related to soy consumption will help you make an informed decision.

Soy has been a common part of the Asian diet for 5,000 years. It was introduced to the United States in the 1800's and today America produces half the world's consumption of soy. Several research studies affirm soy's benefits on health. There is much public awareness about soy. It has been introduced to the public as a food, a food additive, and used extensively in dietary supplements.

Soy is used to boost or benefit health in the following ways:

• To lower cholesterol
• To build bone health
• To lower blood pressure
• To relieve menopausal symptoms such as hot flashes
• To improve memory
• Weight loss enhancement

It is also believed to help reduce the risk of cancers of the breast and the prostate.

Strong or substantial scientific support for the use of soy

• There is substantial evidence from research studies conducted on both animals and human beings that show soybeans can moderately decrease bad cholesterol in the blood.

• Soy contains all of the essential amino acids and therefore is known for its high protein value. Soy protein powders are popular since they offer high protein intake which is low in calories and carbohydrates. They make the perfect protein choice for people who are lactose intolerant and vegans. Soy protein is easy to digest and is also cheaper option than whey protein which is derived from milk. Soy sprout powder contains a highly digestible form of protein which is also rich in vitamins and minerals.

• Initial research studies show that soy may be beneficial in treating infants and children who have diarrhea. Some studies show that soy-based formulas are more effective in speeding the recovery process than cow-based formulas.

Moderate scientific support for the use of soy

• Fermented soy, called nattokinase, has been traditionally used by the Japanese for centuries. It is believed to play a role in lowering blood pressure and in regulating normal blood sugar levels. Research is still being conducted to substantiate these properties.

• Because of its high-protein and fiber content, soy is believed to play a role in weight loss enhancement. Some studies attest that soy has appetite suppressant properties.

• Soy contains isoflavones (a phytoestrogen). Isoflavones are compounds similar to estrogen and are believed to have estrogen-like effects in the body. Soy supplements that contain isoflavones are believed to relieve symptoms such as hot flashes in menopausal women and improve cognitive functions. Soy isoflavones are also believed to increase bone mineral density and decrease the risk of fractures in postmenopausal women. Soy is also known to reduce cyclical breast pain in pre-menopausal women. More research is required to substantiate these findings.

One of the major myths that prevent people from consuming soy is the false belief that soy reduces testosterone levels in healthy men. These myths have since been debunked by scientific research.1

Diverse adaptability, multiple health benefits and economic pricing has made soy one of the most popular herbs today. According to IRI, a Chicago-based research firm, it was listed as one of the top five single selling herbs of 2008. There is no toxicity related to the consumption of soy. However, it should also be noted that soy is one of the eight common allergens.

Consumers are eager to try out soy for specific health needs and innovative products always hold high consumer attraction. Soy beverages, soy-based snacks, and soy milk are the most sought-after soy products.

You can private label a soy supplement formulated by a quality contract manufacturer. Or, contact a knowledgeable soy supplement manufacturer to find out how you can produce a quality soy supplement that meets consumer needs.
