Nitric oxide (NO) is an important signaling molecule that acts in many tissues to regulate a diverse range of physiological and cellular processes. It’s role was first discovered by several groups who were attempting to identify the agent responsible for promoting blood vessel relaxation and regulating vascular tone.
This agent was termed endothelium-derived relaxing factor (EDRF), and was initially assumed to be a protein like most other signaling molecules. The discovery that EDRF was in fact nitric oxide – a highly reactive gas – has led to an explosion of interest in this field, resulted in over 60,000 papers published in the last ten years and won the Nobel prize in 1998.
Nitric oxide has now been demonstrated to play a role in a variety of biological processes including neurotransmission, immune defense, the regulation of cell death and cell motility.
Wondering if nitric oxide supplements will benefit you? Here are 5 reasons to take a nitric oxide supplement:
Whey protein digests rapidly and micellar casein takes a lot longer to be broken down into its amino acid subcomponents. Both types of protein have their place in the supplementation strategies of hard-training adults, but a study presented at Experimental Biology 2012 suggests an alternative.
Researchers found that a protein shake composed of 50% casein, 25% soy isolates and 25% whey isolates prolonged the delivery of amino acids when consumed post-workout. Analyzing the response on 19 young recreationally active adults, they found that this custom protein blend provided a constant supply of amino acids for the longest period of time.
True Strength Moment: Whether this blend produces similar results for older athletes or active adults who engage in different types of exercise is unknown. Recreating the formula is easy enough for anyone with an electric blender or shaker cup to experiment with. But don’t stop there.

Fats get a bad rap most of the time, especially during those last few months of Spring which is beach body crunch time. But not all fat is bad. Your body actually needs essential fatty acids for a wide range of metabolic functions, and a study published in The American Journal of Clinical Nutrition has potentially uncovered an interesting side benefit.
Researchers recruited 45 women in their 60s and assigned them to a strength training program. Some of these volunteers consumed 2 grams of fish oil per day for 90 days or 150 days before the training program started. The rest didn’t supplement with fish oil at all. While all subjects realized benefits from strength training, those who supplemented achieved the greatest increases in muscle strength and functional capacity.
True Strength Moment: Researchers theorized that the omega-3 fatty acids in fish oil might have a role in the cellular function of muscles. Whether fish oil supplementation can have the same impact on younger adults isn’t known, but if you aren’t getting enough cold water fish in your diet, you might want to see what supplemental fish oil can do for your weight training program.
Fish Oils contain long-chain fatty acids, with equally long names like docosahexenoic acid (DHA) and eicosapentaenoic acid (EPA). DHA and EPA are essential fats that cannot be made by your body. So, consuming them through foods like salmon and supplements such as the ON Fish Oil Softgels is the only way to get DHA and EPA. Better yet, our Fish Oil Softgels are enteric coated, which means that you get all of the benefits of fish oils without the fishy aftertaste that you might encounter without this special coating.

This protein-packed powerhouse has benefits beyond great taste.
Muscle Gain & Weight Loss
Lean beef is a complete protein source, containing all the essential amino acids necessary for building and maintaining muscle mass.
A 3-oz serving of T-bone steak contains 22 grams of protein-which, if you’re looking to shed a few pounds, can help you stave off hunger and feel fuller for longer.
A study conducted by Australia’s national science agency found that overweight and obese men using a high-protein diet (with lean red meat) reduced ab fat more effectively than those on a high-carb plan.
Red meat provides the majority of zinc for most Americans, according to the National Institutes of Health.
The high levels of zinc in red meat help ward off illness – and researchers believe zinc can reduce the severity and duration of common cold symptoms.
“Red meat also supplies vitamin B12,” says Jim White, R.D., a spokesman for the American Dietetic Association.
“This helps the body make DNA and keeps nerve and red blood cells healthy.”
A 2012 study published in the American Journal of Clinical Nutrition found that participants who incorporated lean beef into their everyday diet experienced a 10% reduction in their LDL (bad) cholesterol.
The zinc in beef is essential for testosterone production – which helps boost sex drive – and can help reduce blood prolactin levels.
Prolactin is a brain chemical responsible for the refractory period: the amount of time it takes for you to get it back up for Rounds 2 and 3. Less prolactin, less recovery time, better you in the sack.
One of the best mass-building exercises is the deadlift. The act of hoisting a weight off the floor and standing up with it recruits the muscles in your legs and back, which include the most powerful groups in your body. Just like with the squat, tremendous resistance can be utilized. That’s why these exercises are included as two of the three lifts in powerlifting competition.
Any movement that recruits several muscle groups at once requires great care to be taken, and the deadlift is no exception. Because your lower back with be focal point of the exercise, there’s a risk of muscle strain or even injury if you don’t maintain proper form.
To begin the deadlift, position your feet shoulder width apart and bend the knees with your back straight. Grab the bar with your hands positioned just outside of your stance. You can use an overhand grip with both hands or grab the bar with one hand over and the other under to better secure the bar.
You might think that losing weight increases your metabolic rate, but a study published in the International Journal of Obesity suggests the opposite is true. Researchers found that a decrease in metabolic rate was proportional with weight loss, which helps explain weight regain in approximately 95% of people who are initially successful at dropping some pounds. Here’s the good news: combining exercise with a low-fat diet helps preserve muscle mass which prevents this decrease in metabolic rate.
True Strength Moment: Your metabolic rate helps determine the number of calories you burn. When it slows down, you aren’t able to burn up as many calories which makes it more difficult to keep your weight from creeping back up. Exercise seems to be the answer, building muscle mass to increase your metabolism while also enhancing your strength and physical appearance.
