Product Description - Daiwa Health Development Peak Immune 4 250 mg 50 Vegetarian Capsules

Hoxsey Red Clover Burdock Plus Blood Cleansing Herbal Formula

The ingredient in PeakImmune4, Rice Bran Arabinoxylan Compound, is a derivative of rice bran. It has been shown to possess significant immunomodulating properties.

PeakImmune4 is the brand name in the US for the dietary supplement containing RBAC. The supplement is known as BioBran MGN-3 in other parts of the world. It is a dietary supplement for strengthening the immune system

Hemicellulose , a water soluble extract of rice bran is reacted with an enzyme complex extracted from Shitake mushroom. The enzyme is used as a natural scissor that cuts the large hemicellulose molecule, producing a smaller molecule that is more bio-available but still has the key chemical functional groups that provide the immune enhancing benefits. The enzyme complex selectively breaks some chemical bonds but not others. The process, which takes two weeks, is patented. A major benefit of the process is that the batch to batch inconsistency that may result with natural products is eliminated, resulting in a product that is very consistent in performance.

PeakImmune4 Q&A

The key to good health is a strong immune system. It's the best way to effectively combat pollution, poor diet, allergens, medications, insufficient rest, stress, heredity, and aging.

Q. What Is PeakImmune4?

A. It is a dietary supplement that benefits the immune system. The main ingredient is a Rice Bran Arabinoxylan Compound (RBAC). RBAC is polysaccharide dietary fiber from rice bran that is modified by an enzyme from Shiitake mushroom using the latest biotechnology.

Q. Can I get the same benefits provided by PeakImmune4 if I eat rice bran?

A. No, rice bran is very poorly digested. Due to the special modification process, Rice Bran Arabinoxylan Compound is digested and absorbed to a much greater extent. This in turn significantly increases the benefit to the immune system.*

Q. How does it work?

A. PeakImmune4 is an immune modulator. It increases the activity of Natural Killer Cells (NK Cells) and increases the level of T and B cells.* PeakiImmune4 increases the level of both helper and cytotoxic T cells. All three are types of white blood cells. It also supports the body’s natural development of cytokines.* All are important components of the immune system. PeakImmune 4 also is an anti-inflammatory and anti-oxidant.

Q. What is the effect of PeakImmune4 on NK Cells?

A. In vivo clinical studies have shown that it can triple NK activity.

Q. What are cytokines?

A. Small proteins that act as messengers in an immune response.

Q. What are the benefits of PeakImmune4?

A. It maintains a strong immune system and can be used over a prolonged period of time.*

Q. Who should take PeakImmune4?

A. People with severely suppressed immune systems. Anyone who wants to support the strength of their immune system and those that have a good immune system and want to maintain it and not allow daily stress and environmental factors to weaken it.*

Q. What is the proof that Peakimmune4 works

A. It is supported by numerous invivo and invitro studies and has been on the market for over 15 years with 10s of thousands of users globally

Q. What is the dosage?

A. Follow the suggested dosage on the label: As a dietary supplement take 4 capsules a day before or after meals. For the best results (for those with suppressed immune systems), the following two-step program is recommended: 1st Step – Take 4 capsules 3 times a day for 4 weeks. 2nd Step – After 4 weeks reduce the dosage to the maintenance level of 4 capsules a day.

Q. How much Rice Bran Arabinoxylan Compound (RBAC) is contained per capsule of PeakImmune4?

A. 250mg.

Q. Is it preferable to take PeakImmune4 before or after a meal?

A. It is said that a complex sugar is better absorbed after meals. Since PeakImmune4 is a complex sugar, the same principle applies.

Q. How soon should you expect to see the effect of PeakImmune4?

A. Studies showed that taking 3g/day (12 capsules) enhanced the NK cell activity in about 1 to 2 weeks. Maximum NK Cell activity is achieved in about one month when taking 12 capsules a day. Four capsules a day (1g) results in maximum NK Cell activity in about two months.

Q. May I take more than 12 capsules per day?

A. We do not have any data on taking more than 12 capsules a day. What we do know is that taking 12 capsules a day will give you an initial boost in NK cell activities in about 2 weeks, whereas taking 4 capsules a day will gradually increase the NK cell activities and eventually catch up to the level of 12 capsules a day in about two months. This information may help you to make your own decision but we recommend the amount suggested on the label.

Q. How long do I need to take PeakImmune4?

A. The research studies show that the activity of NK cells returns to their pre-intake level within about one month after use of PeakImmune4 is discontinued. Therefore we recommend that you continue to use it for as long as possible.

Q. How long will PeakImmune4 last?

A. The shelf life is two years if exposure to high temperature and humidity is avoided and the seal is kept tight. The expiration date is noted on the label.

Q. Does PeakImmune4 have any side effects?

A. There have been no reported side effects

Q. Is there anyone who should not take PeakImmune4?

A. According to our data, the product has minimum risk of side effects. We have been distributing Rice Bran Arabinoxylan Compound (RBAC) for over ten years in 28 different countries and we have not received any complaints or problems from our consumers concerning side effects. Thus, it appears to be suitable for any users who wish to support their immune systems.* However, it is a dietary supplement and should not be taken to diagnose, treat, cure or prevent any disease. If you have any pre-existing conditions or disease, you should consult with your healthcare practitioner before taking PeakImmune4 (or any dietary supplement). If you are taking immunosuppressant drugs for an organ transplant you should not take PeakImmune4.

Q. I am allergic to mushrooms, can I take PeakImmune4?

A. PeakImmune4 is a rice bran derivative. Only one specific enzyme from Shitake mushroom is used at a very low level to make the Rice Bran Arabinoxylan Compound. However, to be safe, you should either not take the product or start taking it at a low level such as one capsule/day.

Q. Do I need to cycle on and off of PeakImmune4 as is necessary with some other immune support products and dietary supplements?

A. No. It does not lose effectiveness over prolonged use nor does it cause over stimulation of the immune system

Q. Can I take PeakImmune4 with other supplements or with medications?

A. Although there have been no reported cases of interactions with other supplements or with medications, we have not tested PeakImmune4 with other dietary supplements or drugs. We advise that you consult your physician first if you are taking other dietary supplements or medications.
