Strength coach & sports nutrition specialist · · About the author

KLEAN MULTIVITAMIN

  • Klean Athlete Klean Multivitamin provides a broad selection of essential vitamins and minerals, including active forms of folate, vitamin B6, and vitamin B12. Its formula also includes carotenoids and plant extracts for additional antioxidant support. The NSF Certified for Sport designation offers valuable quality assurance for competitive athletes.

However, several nutrients are supplied at relatively high doses, including vitamin B12, vitamin E, and certain B vitamins, while calcium, magnesium, and potassium are present in modest amounts. The proprietary blend also lacks individual ingredient dosages. Overall, it's a comprehensive multivitamin, but it should complement a balanced diet rather than replace targeted supplementation when specific deficiencies exist.

KLEAN OMEGA

  • Klean Athlete Klean Omega provides 750 mg of combined EPA and DHA per softgel, with a 2:1 EPA-to-DHA ratio. This makes it a practical option for individuals who want to increase their omega-3 intake without consuming multiple capsules. The triglyceride-form fish oil is also a positive feature, offering good bioavailability.

Its NSF Certified for Sport designation provides additional quality assurance for competitive athletes. However, the 750 mg combined EPA and DHA dose is below amounts typically studied for significant triglyceride reduction or certain exercise recovery outcomes. Overall, it's a solid choice for general omega-3 supplementation, particularly for individuals who rarely consume fatty fish.
