Thorne D-1,000 delivers 1,000 IU of vitamin D3 (cholecalciferol) per capsule, the bioidentical form the body produces in response to sunlight. It supports calcium absorption, bone density maintenance, immune function, and mood regulation, making it a practical option for those seeking a lower, daily-maintenance dose of vitamin D.
Why It's Worth Considering: Thorne's NSF Certified for Sport manufacturing and commitment to clean excipients make this a reliable choice for clinicians and health-conscious individuals alike who prefer a conservative, foundational D3 dose.
Take 1 capsule one to three times daily or as recommended by your health professional.
Store in a cool, dry place away from direct sunlight. Most supplements are stable at room temperature (59-77°F). Keep the bottle sealed between uses. Check the label for any specific storage requirements, some probiotics and oils require refrigeration.
Most supplements can be taken together safely. However, some minerals compete for absorption (zinc and iron, calcium and magnesium) and should be taken at different times of day. If you're taking prescription medications, consult your healthcare provider about potential interactions.
Most supplements benefit from consistent daily use over 2-3 months to achieve full effect. Some (like vitamins and minerals) can be taken indefinitely as part of a daily routine. Others (like specific herbs) may benefit from cycling. Follow the product's recommended protocol or consult a practitioner.
Fat-soluble supplements (vitamins A, D, E, K, omega-3, CoQ10) should be taken with a meal containing fat. Water-soluble supplements (B vitamins, vitamin C) can be taken anytime. Minerals are generally best absorbed with food. Probiotics should be taken with or just before a meal. Check the product label for specific timing recommendations.
Track your specific health goals, energy levels, sleep quality, joint comfort, digestion, mood, etc. Most supplements take 2-8 weeks for noticeable effects. For objective measurement, baseline lab tests before starting (and repeat at 3 months) provide definitive evidence. The Gabriel Score incorporates clinical evidence for expected outcomes.
