7-KETO Technical Data Sheet

7-KETOTM is a trademark for our 7-keto-DHEA (7-ketodehydroepiandrosterone)-containing product.

In humans, 7-keto-DHEA is a naturally-occurring metabolite of DHEA (dehydroepiandrosterone).1,2

7-keto-DHEA is clinically proven to be safe,3,4 and it does not convert to active testosterone and/or estrogen.5

Like DHEA, 7-Keto-DHEA is associated with a variety of essential human functions. However, unlike DHEA, 7-keto-DHEA is clinically proven to be safe,3,4 and it does not convert to active testosterone and/or estrogen.5 Research has shown that 7-keto-DHEA is more potent than DHEA in strengthening the immune system,6,7 enhancing memory,8 and inducing the activity of various thermogenic enzymes.5, 9-11

Each capsule contains 25 mg of 7-KETOTM.
The product contains no sugar, salt, yeast, wheat, gluten, corn, dairy products, coloring, flavor, or preservatives.

Research has shown that 7- keto DHEA enhances humoral and cell-mediated immunity.6 Furthermore, 7- keto-DHEA appears to enhance the immune response when the normal immune response is less than optimal.7
In addition, in animal studies, 7- keto-DHEA enhanced memory in mice with impaired memory.8
7- keto-DHEA has also been shown to induce the activity of various thermogenic enzymes.5, 9-11

One capsule two to three times daily, as an addition to the everyday diet.

Use of 7-KETOTM is clinically proven to be safe.3,4

60 capsules per bottle.

Store at controlled room temperature, 59o to 86 o F (15 o – 30 o C).
