What Severity, Likelihood & Evidence Mean

Severity — How Serious It Can Be

  • Major. Clinically significant; generally best avoided, or used only under direct professional supervision.
  • Moderate. May need monitoring, a dose adjustment, or separating the times you take each one.
  • Minor. Generally not clinically significant, but still worth noting and mentioning to your pharmacist.
  • No known interaction. Checked against our sources with nothing documented — not the same as proven safety.

Likelihood — How Well It’s Documented

  • Likely. Well-controlled human studies have demonstrated the likely existence of this interaction
  • Probable. Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • Possible. Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists
  • Unlikely. Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans.

Where This Data Comes From

  • Interaction records are evidence-graded and sourced from the Natural Medicines database (TRC Healthcare), the same reference used by pharmacists and hospitals.

Lunasin: Uses, Safety & Side Effects

The bottom line

Lunasin is a small protein (peptide) found naturally in soybeans and some other seeds and grains. Laboratory and animal studies suggest it may have antioxidant, anti-inflammatory, and cholesterol-related effects, but solid human evidence is very limited. Talk with your pharmacist or doctor before using a lunasin supplement.

Overview

Lunasin is a naturally occurring peptide, which is a small piece of protein. It was first identified in soybeans and is also found in smaller amounts in other seeds and grains such as wheat, barley, rye, and some cereals.

Because it occurs in everyday foods like soy, most people already eat small amounts of lunasin without knowing it. As a supplement, it is usually sold as a concentrated soy-derived protein extract in capsules or powders. People take it hoping to support heart health, the immune system, and overall wellness.

How it works

Lunasin is a peptide that researchers believe can survive digestion well enough to be absorbed in small amounts and reach body tissues. In lab studies, it appears to interact with parts of cells involved in how genes are switched on and off.

Proposed effects from laboratory and animal research include reducing inflammation, acting as an antioxidant, and influencing how certain cells grow. Some studies also suggest it may affect cholesterol processing in the liver.

These mechanisms are not yet confirmed in well-designed human trials, so they should be seen as theories that need more research.

Natural Medicines’ 7-point scale. We show each rating’s label word-for-word.

1EffectiveStrong, consistent evidence it works.
2Likely EffectiveGood evidence, though not yet conclusive.
3Possibly EffectiveSome evidence suggests a benefit.
4Possibly IneffectiveSome evidence it may not help.
5Likely IneffectiveFairly strong evidence it doesn’t help.
6IneffectiveStrong evidence it doesn’t work.
7Insufficient Reliable Evidence to RateToo little research to say either way.
Possibly Ineffective Amyotrophic lateral sclerosis (ALS, Lou Gehrig's disease)
Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research in adults with familial or sporadic ALS suggests that taking specific lunasin products twice daily for 12 months does not improve symptoms or delay symptom progression, as measured by the revised ALS functional rating scale, when compared with historical controls. Additionally, no patients taking lunasin demonstrated reversal of ALS. The products used in this study were all produced by Reliv International, Inc. and were given at the following doses: LunaRich X, 6 capsules twice daily; Provantage, 1 scoop twice daily; Reliv Now, 1.5 scoops twice daily.

Rating & evidence shown verbatim from Natural Medicines

Preliminary clinical research in adults with multiple cardiometabolic risk factors (e.g., low levels of high-density lipoprotein [HDL] or elevated low-density lipoprotein [LDL], triglycerides, fasting blood glucose, blood pressure, or body mass index [BMI]) suggests that taking 168 mg of lunasin-enriched soy extract twice daily for 8 weeks does not affect LDL, HDL, or triglyceride levels when compared with placebo. However, the validity of this study is limited by the very small sample size.

Safety & precautions

Because lunasin is found in common foods like soy, eating it as part of a normal diet is generally considered safe for most people. However, the safety of concentrated supplements taken in larger amounts is not well studied.

People with a soy allergy should be especially careful, since many lunasin products are made from soy and could trigger an allergic reaction. Anyone with a chronic health condition, or who is taking prescription medicine, should check with a pharmacist or doctor first.

For pregnancy and breastfeeding, there is not enough safety information on concentrated lunasin supplements, so it is best to avoid them during these times. Children should also avoid supplement forms unless a healthcare provider advises otherwise.

Side effects

Because lunasin has not been widely studied in humans as a supplement, its full side effect profile is not known. When taken as part of soy foods, it is usually well tolerated.

Possible issues are mostly related to the soy source and may include mild digestive upset such as bloating or gas. Allergic reactions are possible in people sensitive to soy and can range from mild to serious. Stop use and seek medical care if you notice signs of an allergic reaction, such as rash, swelling, or trouble breathing.
