Unfortunately the IOC consensus did not suggest enough Vitamin D to really help - especially for indoor athletes* Sports benefits from up to 50 ng of Vitamin – meta-analysis - Nov 2012* Vitamin D - Legal doping for sports professionals, amateurs and their families (book in German) 2020* Elite Athletes do well with weekly 35,000 IU of Vitamin D – RCT Feb 2017* Which is 5X more Vitamin D than IOC consensus suggests* Athletic performance and recovery benefits of Vitamin D (4000-5000 IU and Vitamin K) – Aug 2015* Collegiate Swimmers getting 4000 IU of vitamin D had fewer injuries – March 2013* Muscle fatigue reduced with 10,000 IU of vitamin D – March 2013* NHL discovers Vitamin D – their ideal is 40-120 ng – 2016* Recent increase in Vitamin D levels in Elite Irish Athletes – Aug 2016* Vitamin D and CBD both benefit sports and are not considered to be doping – Sept 2019* Olympic Athletes and vitamin D - clippings 2009-10---Sports category starts with {include}--- 1. Overview Sports and vitamin D has the following summary{include}---Items in both categories Sports and Omega-3 are listed here: {category}---* * Zinc and Vitamin D category listing has items along with related searches** * Book on Sports and vitamin D - Aug 2011* Is 50 ng of vitamin D too high, just right, or not enough* Vitamin D supplementation guidelines (adults – 50,000 IU per week) – Feb 2017* 50,000 IU/week is 7X more than IOC consensus of 1,000 IU/day

Nutrition usually makes a small but potentially valuable contribution to successful performance in elite athletes, and dietary supplements can make a minor contribution to this nutrition program. Nonetheless, supplement use is widespread at all levels of sport. Products described as supplements target different issues, including the management of micronutrient deficiencies, supply of convenient forms of energy and macronutrients, and provision of direct benefits to performance or indirect benefits such as supporting intense training regimens. The appropriate use of some supplements can offer benefits to the athlete, but others may be harmful to the athlete's health, performance, and/or livelihood and reputation if an anti-doping rule violation results. A complete nutritional assessment should be undertaken before decisions regarding supplement use are made. Supplements claiming to directly or indirectly enhance performance are typically the largest group of products marketed to athletes, but only a few (including caffeine, creatine, specific buffering agents and nitrate) have good evidence of benefits. However, responses are affected by the scenario of use and may vary widely between individuals because of factors that include genetics, the microbiome, and habitual diet. Supplements intended to enhance performance should be thoroughly trialed in training or simulated competition before implementation in competition. Inadvertent ingestion of substances prohibited under the anti-doping codes that govern elite sport is a known risk of taking some supplements. Protection of the athlete's health and awareness of the potential for harm must be paramount, and expert professional opinion and assistance is strongly advised before embarking on supplement use.
