The progesterone in Natpro is identical to the progesterone your body makes. 'Progesterone Ph. Eur. USP JP' is derived principally from stigmasterol, a steroidal sapogenin. Phytosterols are chemically similar to cholesterol which is found in animals. Cholesterol is the starting point for the hormones made naturally in animals, including humans. Plants such as the soy bean, Dioscorea species of yams, fenugreek, sisal, calabar bean, some lilies, yucca, some solanum species, maize and many more contain phytosterols, some of which are stigmasterol, diosgenin, sitosterol, campesterol, hecogenin, smilagenin, sarsasapogenin, solasodine. As these sterols have a similar molecular structure to progesterone they are used as starting points for the synthesis of progesterone. In the southern United States the sweet potato (Ipomoea batatas) is called a yam, as are some edible members of the aroids. These plants do not contain any sapogenins. Don't confuse Natpro progesterone cream with a bean or yam "extract". Such extracts do not contain progesterone and are generally a waste of money.
caprylic/capric triglyceride - is a 'medium chain' triglyceride of fractionated vegetable fatty acids extracted from coconut oil. It is colourless, neutral in odour and taste and has a very low viscosity. It has very good resistance to oxidation. It is an ideal 'carrier' for progesterone, as it penetrates the skin readily and is easily absorbed. It does not leave a greasy film and helps to retain moisture. Very importantly... it's not a mineral oil and is unrefined.Lets examine these points more closely: Mineral oils, being petro-chemicals, are potentially harmful because they are endochrine disruptors. They rob your body of the oil soluble vitamins A, D, E & K , and so deprive you of vital nutrients. Never use any product on your skin that contains mineral oils. Heating or refining any vegetable oil causes damage. The good fatty acids that are found in vegetable oils are turned into bad "trans" fatty acids and the result is highly carcinogenic. Don't use refined oils.
Vitamin E (dl-alpha tocopherol) – All emulsions made with vegetable oils have the potential to go rancid. For this reason dl-alpha tocopherol is used as it’s an ‘in vitro’ antioxidant. Standard preparations contain only 0.1%, however, Natpro progesterone cream contains a further 0.2%.
The new two part emulsifier system – cetearyl olivate/sorbitan olivate – a unique natural PEG-free organic emulsifier from Olive oil. It reduces skin water loss, has a high moisturizing effect, is hypoallergenic and biomimics the skin.
The new natural preservative system- Aspen bark extract – is a natural organic preservative and as such is a unique discovery as it is an effective natural replacement for commonly used harmful chemical preservatives such as the ‘parabens’. It also improves the emollience (the ‘feel good’ factor) of the cream.
dehydroxanthan gum – is an Eco Certified, non GMO film former, fixative and emulsion stabilizer. It provides unprecedented hold under highly humid conditions without being tacky or flaking. It is there to prevent the cream from separating or splitting.
