1. Promote calcium and phosphorus absorption and bone health
Calcium and phosphorus metabolism: Activate intestinal calcium-binding proteins, greatly improve the absorption rate of calcium and phosphorus in the small intestine, and maintain the balance of calcium and blood phosphorus.
Bone mineralization: Promote bone calcium deposition, prevent rickets in children (such as X/O legs), adult osteomalacia and osteoporosis, and reduce the risk of fractures by more than 30%.
2. Regulate immunity and anti-inflammatory
Enhance immune cell activity, promote antimicrobial peptide secretion, and reduce the risk of respiratory tract infections by 40% (when serum 25OHD > 30ng/ml).
Inhibits excessive inflammatory responses and may be amerior in autoimmune diseases such as multiple sclerosis.
3. Nerve and cardiovascular protection
Nervous system: Involved in the synthesis of neurotransmitters (such as serotonin), improves cognitive function, and may alleviate seasonal depression.
Cardiovascular: regulates the renin-angiotensin system, improves vascular endothelial function, and reduces the risk of hypertension by 8%.
4. Muscle function and metabolic regulation
To enhance the contractility of type II muscle fibers, supplementing 800IU per day in the elderly can reduce the risk of falls by 19-23%.
Improves insulin sensitivity, and deficiency increases the risk of type 2 diabetes by 50%
