7-KETO Benefits
• Supports proper immune response.*
• Supports healthy thyroid function.*
• Supports mental well-being and memory.*

Key Features
• Clinically studied metabolite of DHEA.

This metabolite of DHEA will not convert into testosterone and estrogens. That means it provides all the advantages of DHEA (such as a strengthened immune system, enhanced memory, and other support that's beneficial to people as they age) without the safety concerns associated with sex hormones.*

What’s the difference between 7-keto DHEA and DHEA?
DHEA (dehydroepiandrosterone) is a steroid hormone produced by the adrenal glands, which plays a role in healthy aging, immune function, and memory. In the body, DHEA can form sex hormones (estrogen and testosterone) and 7-keto DHEA. 7-keto DHEA has many of the same benefits of DHEA, but does not convert to sex hormones.* 7-keto DHEA is safe and well tolerated.

Introduction
Current understanding of 7-keto-DHEA is primarily due to the work of biochemist Henry A. Lardy, PhD, the Vilas Professor Emeritus of the Institute for Enzyme Research at the University of Wisconsin in Madison. Dr. Lardy is renowned for his research on DHEA derivatives and has published over 400 studies in peer-reviewed scientific journals. Dr. Lardy's research has proven that 7-keto-DHEA is chemically distinct from DHEA. Once 7-keto-DHEA is derived from DHEA, it cannot convert back to DHEA; nor can it convert to estrogen, testosterone, or other steroid hormones in the body.*

How Does It Work?
Made in the adrenal glands and synthesized from pregnenolone, the body's “master hormone,” natural DHEA is the precursor to more than 150 individual metabolites. One of the most important DHEA metabolites is 7-keto-DHEA. Researchers have learned that both DHEA and 7-keto DHEA provide support of immunomodulatory activities, enhancement of cognition, memory storage and retrieval, and weight management.*

As DHEA is the major androgen precursor in humans, men have 30 percent higher DHEA levels than women throughout their lives. In both men and women DHEA levels rise through childhood and adolescence until about the age of 20, then begin to slowly decline around the age of 30. By the age 80, there is an 80 percent reduction in DHEA. Researchers have demonstrated that 7-keto-DHEA declines with age in a similar manner.*

To support healthier aging, it was suggested that DHEA supplements might maintain plasma levels at a more youthful level. However, as a hormone precursor DHEA can convert to estrogen, progesterone, and many other metabolites that have been repeatedly and consistently associated with certain health risks in older individuals. In contrast to DHEA, recent rigorous toxicology, pharmacokinetic, and human safety studies have demonstrated that 7-keto-DHEA:

* Does not convert to estrogen, testosterone, or other steroid hormones.*
* Does not increase or decrease hormone levels.*
* Cannot accumulate in the body over time.*
* Is free of any serious side effects.*

Another major biochemical difference is that, in contrast to DHEA, 7-keto DHEA is much better able to induce thermogenic enzyme activity. Thermogenic enzymes increase the metabolic rate during periods of calorie restriction and diet modification. Research has shown that 7-keto-DHEA is 2.5 times more active than DHEA at inducing the activity of these thermogenic enzymes.*

Memory Storage and Retrieval
Once digested, supplemental 7-keto-DHEA enters the bloodstream and interacts with specific neurotransmitters to support health memory storage and retrieval. In an animal study, Dr Lardy and fellow researchers trained young mice in the use of a water maze. They found that a single injection of 7-Keto (at 24 mg/kg of body weight) reversed experimentally induced memory loss. The scientists then fed 7-Keto or DHEA to older mice that had learned the maze. They discovered that memory of the water-maze training was retained during a four-week test period in the mice receiving 7-Keto, but not in those treated with DHEA.*

Thyroid Function
Use of 7-Keto to safely support healthy thyroid function has been established. Thirty study participants with BMI > 30 were instructed to exercise three times per week for 45 minutes, eat 1,800-calories each day, and take 100 mg of 7-Keto or a placebo twice daily. Although the participants' levels of T3 did not exceed the normal range, the 7-Keto group had a significant increase in levels of T3, a thyroid hormone that plays a major role in determining a person's metabolic rate.*

Immune Responses
Communication between immunomodulators and 7-keto-DHEA may result in healthy immune system responses. In a randomized, double-blind, placebo-controlled study, 22 women and 20 men over the age of 65 took either 100 mg of 7-Keto twice daily or a placebo. Patients in the 7-Keto group had significant increase in immune helper cells and a significant decrease in immune suppressor cells. The study also demonstrated that 7-Keto was well tolerated and had no serious adverse effects.*

Thermogenic Action
Thermogenesis, the creation of heat, is a form of energy produced during metabolism. Nutritional support of thermogenesis may boost the body's metabolic rate. Researchers have determined that 7-Keto supports the activity of thermogenic enzymes.*

Two clinical trials, both published in peer-reviewed scientific journals, demonstrated 7-Keto's effectiveness in healthy weight loss. Each of these studies were double blind and placebo controlled and performed in population of overweight men and women over a period of 8 weeks. The results of each study confirm that administration of 7-Keto at a dose of 100 mg twice daily, when combined with a program of diet and exercise, will result in a three-fold increase in weight loss and fat loss compared to placebo.*

Conclusion
Supported by 45 research papers and lab research and five clinical trials, the 7-Keto in 7-KETO provides significant dietary support of proper immune response, healthy thyroid function, memory storage and retrieval, and safe weight loss.*

Quick Tips

Good health doesn't have to be complicated. There are plenty of common-sense steps we can all follow to live better, more active, and fuller lives.

Eat right
We hear this so often it almost loses meaning. Eating right should mean adding things to your diet--more veggies, more fruits, more rich-tasting high-fiber breads and grains. However, it doesn't necessarily mean you have to give up chocolate. After all, there's plenty of beneficial flavonoids in those dark chocolate bars, right? You may just not want to eat chocolate at every meal. Instead of swearing off your favorite (but not healthy) meal forever, try just cutting it down to once or twice a month--make it a treat. As you incorporate more healthy, whole foods into your diet, you'll probably find yourself craving them instead of the bad stuff.

Exercise daily
You don't have to run a marathon or lift your neighbor's house. But, you can start parking a little further away at work each day. Begin taking break time walks, especially if the weather is nice. Dust off that bicycle and see if your friends would like to go for a spin. Almost every town has a dedicated group of folks who do some form of fun exercise. Whatever you do, don't overdo it right off the bat, and choose something you really enjoy. After a couple of weeks, your new exercise regimen will become part of your daily routine, as though it had always been that way.

Strength train your brain
Challenge yourself mentally, and not just by trying to keep up at work. Find a class in your off-hours that teaches something you've always been curious about, but has nothing to do with work. Read a book for fun. Start a board game night with your family. Check out those crossword puzzles. Research in recent years shows that learning new skills and interacting with the world keeps our minds younger much longer. You owe it to yourself to turn off the television and fire up some neurons!

Do something for others
Whether you volunteer for a local environmental group, a food pantry, or your church's annual picnic, people generally feel healthier when their focus is outside of themselves.

Drug Nutrient Interactions

Prescription drug listings are not all-inclusive; the drugs listed below are common examples.

Top Drug Categories Interactions
Anti-anxiety
[Buspar^® (buspirone), Ativan^®(lorezepam) - see Benzodiazepines]
Kava - For reasons similar tobenzodiazepines, it is recommended to avoid taking kava with buspirone unless otherwise directed by a licensed healthcare professional.
St. John's Wort, Ginkgo Biloba - Concurrent use of St. John's Wort and buspirone and St. John's Wort and Ginkgo Biloba with buspirone has resulted in mild serotonin syndrome and should be avoided unless directed by a licensed healthcare professional.
Grapefruit Juice - Concomitant administration of buspirone and grapefruit juice should be avoided as it increased the concentration of buspirone in the blood.
Antibiotics
(General) Vitamin K - The use of cefmetazole sodium has been associated with hypoprothrombinrmia and treated with Vitamin K supplementation.
Antibiotics

(Aminoglycosides, Cephalosporins, Macrolides, Penicillins, Quinolones, Sulfonamides, Tetracyclines) Calcium, Iron, Magnesium, and Zinc - May prevent the absorption of tetracycline, ciproflaxin, and other antibiotics.
Antibiotics

Gentamycin and Penicillians Potassium Chloride - Concomitant administration of gentamycin with potassium chloride may lower the absorption of potassium chloride.
Antibiotics

Extended spectrum Macrolides [Biaxin^®(clarithromycin), Zithromax^®(azithromycin), Erythromycin, and Tetracyclines] Antacids - Antacids containing magnesium and aluminum have been shown to interfere with azithromycin absorption. People can avoid this by taking azithromycin two hours before or after any aluminum or magnesium containing products. Studies show the magnesium typically found in supplements affects absorption of azythromycin.
Anti-Diabetic
[Glucophage^®(metaformin), Actos^®, Avandia^®(pioglitazone)] DHEA(Dehydroepiandrosterone) - Metaformin has been shown to increase levels of DHEA in blood.
Antihistamines

[Claratin^®(loratadine), Allegra^®(fexofenadine)]
St. John's Wort - Concomitant use of St. John's Wort can have an effect on plasma levels of fexofenadine.
Fruit Juices - Co-administration of grapefruit, orange, and apple juices decreases the absorption of fexofenadine.
Anti-Psychotics
[Zyprexa^®(olanzapine), Risperdal^®(risperidone)]
Vitamin B₆ and E - Reported to effectively treat risperidone-related neuroleptic malignant syndrome.
Glycine - Glycine in combination with anti-psychotic treatment has shown significant effects on the effectiveness of these drugs. While adjunctive glycine treatment has been shown to improve negative symptoms in combination with clozapine, olanzapine, and risperidone, additional studies have shown it to be ineffective in combination with clozapine.
Supplementation with glycine in combination with an anti-psychotic should only be done under the supervision of a healthcare professional.
Anti-Seizure

[Tegretol^®(carbamazepine), Dilantin^®(phenytoin), phenobarbital and Mysoline^®(primidone). Depakene^®(valproic acid) and Depakote^®(divalproex) are also anticonvulsant drugs.] Magnesium, Black Pepper, and Caffeine - Concomitant administration of phenytoin (Dilantin^®) or phenobarbital with magnesium oxide may lower magnesium oxide's absorption. Concomitant administration of Dilantin^® and black pepper and/or long pepper may cause the phenytoin to be absorbed more rapidly and eliminated more slowly. Phenytoin also increases the metabolism and loss of caffeine from the body.
Benzodiazepines
Kava - Due to the similarity of effects, it is usually recommended to avoid taking Kava with Benzodiazepines unless otherwise directed by a licensed healthcare professional.
St. John's Wort - Concomitant administration of St. John's Wort with alprazolam and should be avoided unless otherwise directed by a licensed healthcare professional.
Beta-Blockers Potassium - Concomitant use of certain Beta-Blockers may increase potassium levels.
Pepper (Piper Nigrum, Piper Longum) - In single dose human study, piperine, a chemical found in black pepper and long pepper, was reported to increase blood levels of propranolol, which could increase the activity and risks of the drug's side effects.
Antacids - One study showed a reduction in absorption of Sotalol(Betapace^®) when taken concomitantly with an aluminum oxide or magnesium hydroxide antacid. This interaction can be avoided by taking the medication two hours apart.
Magnesium - Magnesium has been effectively used to treat heart arrythmias that have resulted from administration of Sotalol(Betapace^®).
Calcium Channel Blockers Calcium - High level calcium supplementation may reverse the blood pressure-lowering actions of some calcium channel blocker drugs.
Vitamin D - Vitamin D may interfere with the effectiveness of verapamil.
St. John's Wort - A recent study showed that St. John's Wort decreased the bioavailability of R- and S-verapamil.
Fruit Juices - Ingestion of grapefruit, grapefruit juice, and grapefruit products has been shown to increase the adverse effects of calcium channel blockers or similar drugs.
Diuretics, Potassium-Sparing

[Amiloride, Aldactone^®(spironolactone), Dytac^®(triamterene)] Magnesium - Magnesium tends to be preserved.
HIV Antivirals St. John's Wort - St. John's Wort has been shown to speed up the elimination of indinavir which may result in resistance to the drug. St. John's Wort should not be taken concomitantly with HIV Antivirals.
Sho-Saiko-To - This herbal medicine has been shown to enhance the antiviral activity of lamivudine.
Carnitine- Depletion of Carnitine levels may be responsible for muscle and nerve damage in patients on Antiviral therapies. Carnitine supplementation is recommended.
Antioxidants- A small study showed a positive effect of antioxidant supplementation on hyperlactatemia (elevated levels of lactate in the systemic circulation) in patients on long-term Antiviral therapy.
N-Aceylt Cysteine- Studies have shown supplementation with NAC during Antiviral therapy may reduce AZT toxicity.
Vitamins E and C- Supplementation with Vitamin E has shown to improve the efficacy of AZT and supplementation with Vitamins E and C may reduce AZT-related cellular damage.
NSAIDs (non-steroidal anti-inflammatory drugs) Copper - Copper may enhance the anti-inflammatory effects of NSAIDs. Indomethacin may cause sodium and water retention.
Non-Narcotic Pain Relievers
[Imitrex^®(sumitriptan), Ultram^®(tramadol)] St. John's Wort - Potential interactions may occur. Concomitant administration is not advised unless prescribed by a health care professional.
Oral Contraceptives St. John's Wort - Concomitant use of St. John's Wort and oral contraceptives may reduce the effectiveness of the contraceptives and cause breakthrough bleeding.
Serum Iron and Copper - Oral contraceptive use has been associated with an increase in iron and copper levels.
Respiratory Corticosteroids Calcium - Calcium absorption was reduced following administration of oral beclomethasone (inhaler), a respiratory steroid similar to Flonase^®.
Synthetic Thyroid Iron and Soy - Iron supplements and soy products taken at the same time as thyroid hormone replacement may interfere with absorption. Thyroid hormone absorption is increased when taken on an empty stomach. Thyroid hormones should be taken an hour before eating, at the same time every day.

For support of overall health in any individual, the appropriate comprehensive age- and gender-specific multiple formula, flax oil, and multiple antioxidant formula are recommended. However, for a specific potential deficiency, individuals may add single ingredient supplements to assure repletion. It is important to consider the quality and bioavailability of vitamin and mineral supplements used for these purposes.

7-Keto FAQ

What’s The Difference Between 7-Keto DHEA And DHEA?
DHEA (dehydroepiandrosterone) is a steroid hormone produced by the adrenal glands, which plays a role in healthy aging, immune function, and memory.* In the body, DHEA can form sex hormones (estrogen and testosterone) and 7-Keto DHEA. 7-Keto DHEA has many of the same benefits of DHEA, but does not convert to sex hormones.* 7-Keto DHEA is safe and well tolerated.

Does 7-Keto Raise Levels Of DHEA In The Body?
7- Keto DHEA is irreversibly metabolized from DHEA, and it will not convert to DHEA. Therefore, 7-Keto does not raise blood levels of DHEA in the body.

Can 7-Keto DHEA Cause Irregular Menstrual Periods?
7-Keto is a naturally occurring metabolite of DHEA. It does not convert to active testosterone or estrogen. To date, there is no evidence that 7-Keto would be associated with changes in the menstrual cycle.
