Klean Athlete Klean-D 25 mcg (1,000 IU) - 100 Tablets

Why Do Athletes Need Vitamin D3 Supplementation?

For athletes who train indoors—whether due to weather, safety, or convenience—limited sun exposure can lead to suboptimal vitamin D levels. Since the body synthesises vitamin D when skin is exposed to sunlight, indoor training often means lower natural production. Vitamin D3 supports normal immune function and contributes to normal muscle function, both essential for consistent training and recovery.*

Key Benefits of Vitamin D3

• Immune Function: Vitamin D3 contributes to the normal function of the immune system.*
• Muscle Function: Helps maintain normal muscle function, important for athletic performance and recovery.*
• Indoor Training Support: Provides targeted supplementation for athletes with limited sun exposure.*

It is third-party certified by NSF International’s NSF Certified for Sport programme, helping athletes, coaches, and trainers make informed choices about sports supplements.

How to Choose the Right Dosage

The recommended daily allowance (RDA) for vitamin D is 600–800 IU for most adults, but many experts suggest 1,000–2,000 IU for maintenance. Klean-D provides 1,000 IU per tablet, making it suitable for daily uses. Athletes with higher requirements or those with a known deficiency should consult a health care professional for individualised dosage. Blood testing can help determine optimal levels.
