How It Works
How It Works
Vitamin D3 (cholecalciferol) is the same form your skin produces from sunlight. Your body converts it into an active hormone that regulates calcium absorption, supports immune cell function, and influences mood-regulating pathways. The olive oil base enhances absorption since vitamin D3 is fat-soluble.
Who It's For
Adults living in Canada who get limited sun exposure, especially during winter months. Office workers, shift workers, or anyone wanting consistent vitamin D3 levels year-round. Those focused on maintaining strong bones and immune function.
Who It's Not For
Not suitable for children without medical supervision. Those already taking high-dose vitamin D should consult healthcare providers to avoid exceeding safe levels.
About This Product
What It Does
NOW D3 High Potency delivers 2500 IU of vitamin D3 per softgel to support immune function, bone health, and mood balance when sun exposure isn't enough. This bioavailable form helps your body maintain optimal vitamin D levels throughout the year. Each softgel provides a concentrated dose in an easy-to-swallow format.
Why It Works
- IMMUNE FUNCTION: Vitamin D3 supports immune cell activity and helps maintain your body's natural defense mechanisms against seasonal challenges.
- BONE HEALTH: Essential for calcium absorption — without adequate vitamin D3, your body only absorbs 10-15% of dietary calcium versus 30-40% with sufficient levels.
- MOOD SUPPORT: Helps maintain healthy mood and mental well-being, particularly important during darker months when natural vitamin D production decreases.
- CARDIOVASCULAR SUPPORT: Research suggests vitamin D3 may help maintain healthy blood pressure and circulation patterns.
- MUSCLE FUNCTION: Supports normal muscle function and physical performance — vitamin D3 receptors are found throughout muscle tissue.
What's Inside
