An energy boost before your workout is a welcome idea. There are numerous powders and drinks on the market but are they safe? In moderation, probably. In many the main ingredient is caffeine which in appropriate amounts is likely safe and effective. If your heart races or your fingers tingle that’s too much.
Some experts recommend going more natural because then there is less concern with what other ingredients might be in that powder. So instead, have a cup of coffee before working out. Or food rich in protein like yogurt.
Use common sense. We don’t want to over stress our bodies. Yet it’s important to keep moving as we age.
