Is Solius NSF Certified for Sport? Is it safe for athletes?

Yes, Solius is safe for athletes because it works through light rather than oral supplementation, meaning no substances are introduced into the body that would appear on banned substance lists or interfere with training, recovery protocols, or competition schedules.The single weekly session format also fits easily around demanding training calendars.

Athletes searching for NSF Certified for Sport vitamin D options should know that NSF's Certified for Sport® program, the gold standard for athlete supplement safety, certifies ingestible products, not devices. As an FDA-cleared light therapy device, Solius falls outside that certification category entirely. There are no ingredients, fillers, additives, or hidden substances of any kind to evaluate. In that sense, Solius meets and exceeds the spirit of Certified for Sport® standards — because there is nothing in it.
