Dr. Ray Peat’s Progesterone



Dr. Ray Peat's progesterone oil is the best natural progesterone supplement. It provides natural progesterone in a very absorbable form and is about 20 times stronger than other natural progesterone supplements on the market.

What is Natural Progesterone?

Progesterone is a natural hormone that is usually referred to in regards to women, but both men and women produce progesterone. Progesterone belongs to the body’s youth-associating hormones, which all have anti-stress and anti-aging effects.

Progesterone is the body’s most protective hormone. It neutralizes inflammatory substances including excess estrogen. As explained in another blog post estrogen contributes to chronic inflammation.

Together with optimal thyroid function, good progesterone levels are essential for the body’s energy production. When the cells of your body are producing an abundance of energy then repair and healing can take place.

Natural progestertone versus Synthetic progestins?

If you have signs and symptoms of progesterone deficiency supplementing progesterone is an option.

According to Dr. Ray Peat, both men and women can benefit from using a natural progesterone supplement. However, it is essential that the progesterone supplement has been manufactured correctly.

First of all is very important not to confuse natural progesterone with synthetic progestins, which are modifications of progesterone, having atoms introduced into the natural molecule, to create patentable drugs. Many of the progestins have very harmful effects.

The drug companies make progestins because it is not possible to patent a natural substance like progesterone.

In contrast to progestins, natural progesterone is bio-identical, meaning it is similar to the progesterone produced by the body.

What is the best natural progesterone supplement?

There are many different natural progesterone products on the market. The only one we recommend is Dr. Ray Peat’s Progesterone oil also called Progest-E (Produced by Kenogen).

Dr. Ray Peat’s progesterone supplement differs from all other natural progesterone products, as it is made in a special way using vitamin E as a solvent for the progesterone. This allows for an effective oral progesterone supplement with very high bioavailability.

Dr. Ray Peat’s Progesterone oil is about 20 times stronger than other progesterone preparations. Thus high dosages are not necessary, which is often the case with other preparations.

Dr. Ray Peat holds the patent on using vitamin E as a solvent for progesterone. Many other companies are trying to simulate Dr. Ray Peat’s progesterone oil. Some companies are even claiming they have a better product and try to confuse people with misleading statements about Dr. Ray peat’s Progesterone product.
