If you're looking to build muscle, boost your performance, and make the most out of all your hard work in the gym, whey protein is the way to go. Research suggests that using whey protein powder along with resistance training can help maintain lean body mass and increase upper and lower-body strength. But walk through the aisles of any supplement store, and you'll see a wide variety of different protein types. So why whey? One of the major benefits of using whey protein is that it contains a wide range amino acids not seen in plant-based protein products, like pea or hemp proteins, says Marie Spano, M.S., sports nutritionist for the Atlanta Hawks, Braves, and Falcons. There is also an abundance of essential amino acids in whey protein, one of which is leucine. Leucine is needed to 'turn on' muscle building at a cellular level, according to Mike Roussell, Ph.D., author of The Meta Shred Diet. But keep in mind — you need to put in the work in the gym for your w...

You’ve probably heard someone say, “Eat your carrots, they’re good for your eyes.” You may have also seen advertisements for nutritional supplements for eye health. Can vitamins and minerals benefit your eye health and vision? Keep reading to learn more about supplements and eye health. What science has to say Plenty of claims are made about the positive effects of supplements on vision and eye health, but very few research studies support these claims. One exception is the Age-Related Eye Disease Studies (AREDS and AREDS2). These are large studies conducted by the National Eye Institute. Results from AREDS 2 took what was learned from AREDS and improved the supplement recommendations. The studies focused on two conditions that affect millions globally, age-related macular degeneration (AMD) and cataracts. Age-related macular degeneration (AMD) AMD is the leading cause of vision loss in the United States. It affects more than 10 million people. It’s mainly associated with...

Abstract Background: Monotherapy approaches in clinical nutrition frequently fail to address the highly integrated metabolic loops governing human physiology. The widespread administration of high-dose Vitamin D3 has exposed a critical clinical vulnerability known as the "Calcium Paradox"—the concurrent development of skeletal mineral deficiencies alongside soft tissue and vascular calcification. Objective: This review maps out the complete systemic, molecular, and genomic interactions of a quadpartite biological network: Cholecalciferol (D3), Menaquinone-7 (K2), Magnesium (Mg), and Retinol (A). Mechanisms: Vitamin D3 acts as the foundational driver of calcium influx. However, its efficiency and safety are entirely dependent on magnesium for enzymatic conversion, Vitamin A for nuclear receptor heterodimerization, and Vitamin K2 for post-translational modification of calcium-binding proteins. Conclusion: To achie...
