PeakImmune4: The active ingredient in a banned US product reappears in a new immune-boosting formula

Back in July 2004, the US Food and Drug Administration (FDA) forced an Amercian company, Lane Labs, to stop selling their product MGN3. This ruling was not because it was dangerous or ineffective but because the FDA felt that Lane Labs marketing language made disease claims allowed only for FDA-approved drugs.

We originally wrote about MGN3 in the August 1999 issue of HSI. In that article, we told you how the effects of MGN3 were similar to those of pharmaceutical immune system stimulants like synthetic Interleukin-2, but without that drugs toxic and stressing side-effects.

When the 2004 ruling occurred, everyone who had experienced great results with this immune system booster suddenly found themselves without a safe and effective product they could rely on. Since then, weve been keeping our eyes open looking for a natural and effective therapy that would provide similar benefits to the outlawed MGN3 formula.

But were officially calling off the search. A new product called PeakImmune4 was introduced in the US in July 2005 and is now available in the UK for the first time. But as it turns out, PeakImmune4 really isnt new at all. It actually contains the same active ingredient as MGN3 its just being sold by a different company under a different name.

When products change names and hands, it can be confusing and sometimes even disconcerting. And at first it can seem kind of fishy. So we at HSI did some digging to find out if PeakImmune4 was really all it was cracked up to be. What we realized at the end of this winding trail was that to best understand the story, you need to start at the beginning.

PeakImmune4: Connecting the dots

In 1992, Daiwa Pharmaceutical began developing Rice Bran Arabinoxylan Compound (RBAC). RBAC is contained in common grain (rice, wheat, corn, etc), but it cannot be assimilated in our stomach because of its large molecular size. However, Daiwa applied its patented technology and made it possible to break down the size of the molecule. RBAC goes right to the source of ultimate health: your immune system. Human clinical studies have shown that RBAC may be able to increase the activity of Natural Killer (NK) cells, the bodys first line of defence against diseases like cancer, HIV and hepatitis. Studies also show that RBAC increases two other vital immune system cells: T cells and B cells.

Daiwa, which is based in Tokyo, Japan, licensed this patented formula to Lane Labs, which sold it in the US under the trademark MGN3.  

But then in May 2004, the government stepped in and barred Lane Labs from selling MGN3. The FDA did not, however, outlaw RBAC, the compound from which the product was made.

Daiwa was left with a great product but no way to market it in the US. Thats when they decided to branch out and open their own company in the States,
Daiwa Health Development, so they could continue to offer RBAC and introduce other Daiwa supplements to the market.

In July 2005, Daiwa launched PeakImmune4.

It may be hard to find a connection between these two products because you wont find MGN3 mentioned in any of PeakImmune4s promotional materials. Thats because the US courts did more than just forbid Lane Labs from selling MGN3. It also stipulated that the MGN3 brand name could not be used in marketing and promotion of supplements made from the same active ingredient, and that products could not be promoted as replacements or substitutes for MGN3.

However, you can rest easy knowing that this product uses the same active ingredient as MGN3, which means the same research is backing it up.

PeakImmune4: Recommendations for a healthy immune system

Many immune system products require you to cycle on and off. But since PeakImmune4 is not thought to lose effectiveness over time and doesnt cause the immune system to attack itself, you can take it regularly without worrying about side-effects.

Dr. Martin Milner, the medical adviser to HSI in the US, has used the RBAC compound for years. He has monitored its effectiveness in his own patients by testing their NK cell response. Milner found that his patients retained increased levels of NK cell activity even when they used the product for prolonged periods of time.

PeakImmune4: What to take for best results

For the best results, you should follow two simple steps: First, take four capsules three times per day for four weeks (before or after a meal). Then, after four weeks, reduce dosage to the maintenance level of four capsules daily. Each capsule contains 250mg of Rice Bran Arabinoxylan Compound (RBAC).

If you decide to try PeakImmune4 to support your immune system health, you should work with your health care professional, especially if you are pregnant, are nursing, are being treated for any medical condition, are currently taking medications, or have been diagnosed with a health disorder. And if you are taking immunosuppressant drugs for an organ transplant, you should NOT take a product with RBAC in it.
