Rationale & Viability of revised Biotone EFA Formulation
Biotone EFA helps maintain optimal health as supported by various forms of research noted below. Seroyal is continuously researching each ingredient in each one of our formulations against the most recent scientific evidence. As we propose these findings to our expert committee we believe it is sometimes necessary after laborious analysis of the research and our client?s expectations, to optimize our formulations to remain as a leader in the natural pharmaceutical industry.
Changes on the Biotone EFA label:
The phytosterol amount has been increased from 16 mg/capsule to 112 mg/capsule based on recent evidence that phytosterols support cardiovascular health and cholesterol levels already in the normal range.
Along with octacosanol, we have added hexacosanol, tetracosanol, triacontanol and dotriacontanol. All of these components are included under policosanol, because they also support cardiovascular health and cholesterol levels already in the normal range.
Biotone EFA is a unique combination of rice bran, soybean and wheat germ oils specifically formulated to support and regulate hormonal function. Rice bran and wheat germ oils are high in octacosanol, fatty acids, phytosterols, and in ketosteroids, anabolic growth agents, and lipotropic factors. Octacosanol, found in wheat and in rice oil fractions, supports heart health and hormone balance.
How are Essential Fatty Acids (EFAs) broken down in the body? Does it require much work from the liver?
EFAs are broken down in the gut (hydrolyzed) and the individual fatty acids are absorbed by the enterocytes lining the GI tract. The enterocytes assemble the fatty acids and glycerol into triglycerides.The triglycerides and other fat soluble nutrients are collected and assembled into chylomicrons, which are absorbed by the lacteals (lymphatic vessels of the small intestines). The chylomicrons flow with the lymph into the blood and reaches every tissue in the body. In the tissues the triglycerides are absorbed in a similar way as triglycerides are absorbed by the enterocytes. In the tissues the fatty acids can be metabolized into for example local hormones.
The hydrolization process in the gut requires lipase secreted by the pancreas and bile synthesized in the liver and secreted from the gallbladder.

Research & Scientific Rationale Plant sterols are plant compounds with similar chemical structure and biological functions as cholesterol. It has been reported that phytosterols esters help maintain already healthy cholesterol levels.
Sterols are an essential component of cell membranes, and both animals and plants produce them. Sterols are saturate (they have no double bonds in the sterols ring) and are produced by hydrogenating sterols.
One possible effect of plant sterols is their antioxidant activity. It was found that the methanol extract of soybean oil, which has a strong in-vitro protective effect against DNA damage in human endothelial cell, contains phytosterols in addition to tocopherols, Thus based on results from in vitro studies and on human study, there is a possibility that plant sterols may possess antioxidant properties. Such as antioxidant protection could also benefit atherosclerosis (Berger et al, 2004). A recent paper explored the antioxidant properties of plant sterols (campesterol, B-sitosterol, stigmasterol) and reported that phytosterols themselves can act as an antioxidant in-vitro, a modest radical scavenger in solution, and physically as a stabiliser in liposomal membranes (SCF, 2002).

Hormones / Menopause Policosanol prevents bone loss in ovariectomized rats. Noa M, M?s R, Mendoza S, G?mez R, Mendoza N, Gonz?lez J. The purpose of this study was to determine whether policosanol could prevent bone loss in the bones of ovariectomized rats by comparing its effects with those induced by estradiol (sex hormone). In conclusion, policosanol prevented bone loss and decreased bone resorption in ovariectomized rats, suggesting that it should be potentially useful in preventing bone loss in postmenopausal women.

Effects of soy protein and isoflavones on circulating hormone concentrations in pre- and post-menopausal women: a systematic review and meta-analysis. Hooper L, Ryder JJ, Kurzer MS, Lampe JW, Messina MJ, Phipps WR, Cassidy A. Isoflavone-rich soy products decrease follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in premenopausal women and may increase estradiol (sex hormone) in post-menopausal women.

Impact of soy supplementation on sex steroids and vascular inflammation markers in postmenopausal women using tibolone: role of equol production capability. T?rm?l? R, Appt S, Clarkson TB, Mueck AO, Seeger H, Mikkola TS, Ylikorkala O. Soy modified the concentrations of estrone, testosterone and some endothelial markers.

New equol supplement for relieving menopausal symptoms: randomized, placebo-controlled trial of Japanese women. Ishiwata N, Melby MK, Mizuno S, Watanabe S. Equol, a metabolite of the isoflavone daidzein, is hypothesized to play a major role in the health benefits of soy. S-equol supplement improved mood-related symptoms in perimenopausal/postmenopausal equol nonproducers. Menopause. 2009 Jan-Feb;16(1):141-8.
Effects of soy protein isolate and moderate exercise on bone turnover and bone mineral density in postmenopausal women. Evans EM, Racette SB, Van Pelt RE, Peterson LR, Villareal DT. In postmenopausal women soy protein isolate reduces bone turnover with no impact on bone mineral density over 9 months. Menopause. 2007 May-Jun;14(3 Pt 1):481-8.
Androstenedione production by biotransformation of phytosterols. Malaviya A, Gomes J. Androstenedione is a key intermediate of microbial steroid metabolism. It belongs to the 17-keto steroid family and is used as starting material for the preparation of different steroids. Androstenedione can be produced by microbial side chain cleavage of phytosterol, which is an alternative to multi-step chemical synthesis. Bioresour Technol. 2008 Oct;99(15):6725-37.

Endurance / Athletes Octacosanol supplementation increases running endurance time and improves biochemical parameters after exhaustion in trained rats. Kim H, Park S, Han DS, Park T. exercise-trained control group (EC) rats ran 184% longer until exhaustion than sedentary control group rats, while octacosanol-supplemented trained rats ran 46% longer than EC rats. J Med Food. 2003 Winter;6(4):345-51.
