“Estrogen blocker” supplements, do they really work? If so, should people – men in particular – use them? I answer that question in this vid and cover the facts on these supplements as few others can or will…BTW, most of more popular ingredients used in OTC estrogen blocker/anti estrogen supplements used on the market, are covered in detail in my BBR program and SSB book if you want details beyond what this vid covers, either of which can be found in the “Recommended Stuff” section of the site.
Many know Red meat has a reputation for being superior for building muscle, and has for thousands of years, but is it true? I attempt to cover that issue in this vid!

Study mentioned in this vid:

Very limited data suggest that meat consumption by older people may promote skeletal muscle hypertrophy in response to resistance training (RT).
The objective of this study was to assess whether the consumption of an omnivorous (meat-containing) diet would influence RT-induced changes in whole-body composition and skeletal muscle size in older men compared with a lactoovovegetarian (LOV) (meat-free) diet.
Nineteen men aged 51-69 y participated in the study. During a 12-wk period of RT, 9 men consumed their habitual omnivorous diets, which provided approximately 50% of total dietary protein from meat sources (beef, poultry, pork, and fish) (mixed-diet group). Another 10 men were counseled to self-select an LOV diet (LOV-diet group).
Maximal strength of the upper- and lower-body muscle groups that were exercised during RT increased by 10-38% (P < 0.001), independent of diet. The RT-induced changes in whole-body composition and skeletal muscle size differed significantly between the mixed- and LOV-diet groups (time-by-group interactions, P < 0. 05). With RT, whole-body density, fat-free mass, and whole-body muscle mass increased in the mixed diet group but decreased in the LOV- diet group. Type II muscle fiber area of the vastus lateralis muscle increased with RT for all men combined (P < 0.01), and the increase tended to be greater in the mixed-diet group (16.2 +/- 4.4 %) than in the LOV diet group (7.3 +/- 5.1%). Type I fiber area was unchanged with RT in both diet groups.
Consumption of a meat-containing diet contributed to greater gains in fat-free mass and skeletal muscle mass with RT in older men than did an LOV diet.
Or maybe both? In this vid I cover this controversial supplement and give science based advice. An extensive article that examines the study mentioned in this video on the effects of ARA on strength and muscle mass can be read HERE!
Whey protein has become a staple nutritional supplement with both athletic populations requiring the highest possible quality protein to help recuperate from exercise, and those interested in the various health and disease fighting benefits of whey.
However, whey is a complex protein which leads to various questions regarding this biologically active protein. Some of this confusion has stemmed from the marketing efforts of various companies competing for sales in a very competitive market. Some of the confusion stems from a simple misunderstanding of the science of whey.
This Q&A will attempt to address some of the most common questions regarding whey as it applies to some of the major differences between types of whey, such as whey concentrates and whey isolates and other common sources of confusion. For in-depth information on whey and its many potential health benefits, read the “50 Shades Of Whey”
Q1:“What are the essential differences and advantages/disadvantages of each type of whey protein? Isolate, concentrates?”
Is good form during weight lifting essential to gaining muscle mass? Many think good form is an essential factor, but is it? The answer may surprise you!
Viagra and muscle? Does Viagra, or Cialis help build muscle? Athletes from body builders to football players to mountain climbers use these PDE inhibitor drugs. Why? In this vid I cover the facts behind their use.
Sildenafil Increases Muscle Protein Synthesis and Reduces Muscle Fatigue
Clinical and Translational Science
Volume 6, Issue 6, pages 463–468, December 2013
Reductions in skeletal muscle function occur during the course of healthy aging as well as with bed rest or diverse diseases such as cancer, muscular dystrophy, and heart failure. However, there are no accepted pharmacologic therapies to improve impaired skeletal muscle function. Nitric oxide may influence skeletal muscle function through effects on excitation-contraction coupling, myofibrillar function, perfusion, and metabolism. Here we show that augmentation of nitric oxide-cyclic guanosine monophosphate signaling by short-term daily administration of the phosphodiesterase 5 inhibitor sildenafil increases protein synthesis, alters protein expression and nitrosylation, and reduces fatigue in human skeletal muscle. These findings suggest that phosphodiesterase 5 inhibitors represent viable pharmacologic interventions to improve muscle function.
Exercise protects against heart disease in many ways. One important mechanism is by elevating HDL, a.k.a. the “good” cholesterol. It is well established that high levels of HDL are protective against cardiovascular disease and the National Cholesterol Education Program (NCEP) has emphasized increasing HDL levels to help reduce CHD risk. [2-4] However, not only HDL levels are important. Emerging research in showing that HDL quality and function is as important, if not more important for health promotion and prevention of cardiovascular and metabolic diseases…[5-7]
Growth Hormone (GH) supplements have been around forever, and have made a recent come back. Are they legit? Do they increase muscle mass or reduce body fat as claimed? I cover these supplements in this vid!
BTW, My books on the right column of this page cover GH supplements in depth if interested in more info ===>
If you’re following the health news, you know that vitamin D currently is in the media spotlight, and rightly so. Will Brink just did a great podcast “Vitamin D3 – scam or panacea?“, giving an overview on the importance vitamin D. In this article I will expand upon some key points taken up in the podcast, and back up the case with a solid reference list of recent studies on the topic. I will also present some revealing prevalence stats on vitamin D insufficiency, in order to convince you to get your blood levels checked to find out your vitamin D status.
Vitamin D is interesting for several reasons:
1. The role of vitamin D for health promotion has undergone a paradigm shift. While traditionally thought to only be important for development and maintenance of strong bones, an impressive body of scientific research has accumulated over the past decade, showing that adequate vitamin D levels are necessary to prevent many diseases, especially cardiovascular disease, high blood pressure, endothelial dysfunction, diabetes (both type-1 and type-2), the metabolic syndrome, chronic inflammation, cancer, osteoporosis (including falls and fractures), muscle weakness, cognitive dysfunction and mental illness, autoimmune diseases (e.g. multiple sclerosis, rheumatoid arthritis), infectious diseases, as well as infertility and adverse pregnancy and birth outcomes [1-24].
Vitamin D deficiency/insufficiency is associated with all-cause mortality , and supplementation has been shown to decrease mortality rates [25, 26]. It has been estimated that doubling vitamin D levels in the general population (from 21 ng/mL to 44 ng/mL) would reduce vitamin D-related disease mortality rate by 20%, and increase life expectancy with about 2 years .
2. Insufficient levels of vitamin D also have direct implications for fitness enthusiasts and athletic performance, due to the importance of vitamin D for muscle function (I will cover this in much more dept in an upcoming article) [28-39].
3. In contrast to other vitamins, vitamin D deficiency/insufficiency is very common (more on that below).
4. The vitamin D requirement for health promotion and protection against the mentioned diseases and muscle dysfunction is much higher than the dietary recommendations (RDA) for bone health [4, 40-45].
Having heard about all the vitamin D benefits you might wonder what is the optimal vitamin D level? How low is too low and how high is too high? How much vitamin D does one have to consume to reap all the benefits? Let’s find out…
