土曜日に鹿児島県体育協会スポーツドクター協議会の研修会に参加した

その際、日本陸連理事、JADA理事、JOCアンチ・ドーピング委員などを務められている山澤文裕先生が、最近のIOCのサプリメント摂取に関する声明を紹介されていた。

それを受けて日本陸連は、サプリメントを『使わせない』から、安全に効果的に使えるように、科学的根拠をもとに検討する方向に舵をきった。

それに合わせて、「サプリメント摂取の基本8箇条～摂るときは、必要な分だけ上手に安全に～」等の資料を作成しホームページで公開している。

（ホームページで公開しているとのことだったが、見つけ切れていない・・・）

「サプリメント摂取の基本8箇条～摂るときは、必要な分だけ上手に安全に～」

1. サプリを摂る前にまずは”食事の改善”を
2. 確かめよう！サプリを摂る”目的と使いかた”
3. サプリの摂りすぎはむしろ”健康へのリスク”あり
4. 「これに効くよ」と言われたサプリに用v風位
5. ”絶対に安全”そんなサプリはありません
6. 気を付けよう！”海外サプリ”の安易な使用
7. サプリによるドーピングは”自己責任”
8. サプリを摂る前に医師・栄養士。薬剤師へ”相談を

Consensus statement

IOC consensus statement: dietary supplements and the high-performance athlete

Abstract

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 programme. Nonetheless, supplement use is widespread at all levels of sport. Products described as supplements target different issues, including (1) the management of micronutrient deficiencies, (2) supply of convenient forms of energy and macronutrients, and (3) provision of direct benefits to performance or (4) indirect benefits such as supporting intense training regimens. The appropriate use of some supplements can benefit the athlete, but others may harm the athlete’s health, performance, and/or livelihood and reputation (if an antidoping 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 trialled in training or simulated competition before being used in competition. Inadvertent ingestion of substances prohibited under the antidoping 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; expert professional opinion and assistance is strongly advised before an athlete embarks on supplement use.

Unapproved Pharmaceutical Ingredients Included in Dietary Supplements Associated With US Food and Drug Administration Warnings

https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2706496

Key Points 

Question

What are the trends across adulterated dietary supplements associated with a warning released by the US Food and Drug Administration from 2007 through 2016?

Findings

In this quality improvement study, analysis of the US Food and Drug Administration warnings from 2007 through 2016 showed that unapproved pharmaceutical ingredients were identified in 776 dietary supplements, and these products were commonly marketed for sexual enhancement, weight loss, or muscle building. The most common adulterants were sildenafil for sexual enhancement supplements, sibutramine for weight loss supplements, and synthetic steroids or steroid-like ingredients for muscle building supplements, with 157 products (20.2%) containing more than 1 unapproved ingredient.

Meaning

Potentially harmful active pharmaceuticals continue to be identified in over-the-counter dietary supplements.
