This is a review of product:

Peak Performance Advanced Vitamin D 5000 IU with All 3 Types of Vitamin K Vitamin D3 and Vitamin K2, K1, MK-7 (MK7), MK4 Supplement. 60 Small and Easy to Swallow Vegetable Pills (5000 IU)

I don't know how good they are as I received an empty box. So I did get the item and took the pills. I bought them because I was having bruising problems lately. So far I am bruising less and when they do happen they disappear faster. There was one surprising side effect though I noticed after a few days my breathing was getting easier and I was coughing less. My COPD seems to have improved as well because of the D3. I read later that D3 helped COPD and now I will ask my doctor why he never told me about this,

Vitamin Basics & Tips

Vitamin D3 plays a critical role in immune function and inflammation regulation, which may explain its reported benefits for COPD patients. Studies suggest adequate vitamin D levels can reduce respiratory infections and improve lung function by modulating immune responses. Additionally, vitamin D aids calcium absorption, supporting bone health and potentially minimizing bruising susceptibility by strengthening blood vessels.

Daily sunlight exposure (10–30 minutes) helps the body synthesize vitamin D, but supplements are often necessary, especially for individuals with limited sun access or darker skin tones. The recommended daily intake for adults is 600–800 IU, though deficiencies may require higher doses under medical supervision. Always consult a healthcare provider before starting supplements, as excessive vitamin D can cause toxicity.

Emerging research links vitamin D to improved respiratory health, including COPD management, by reducing airway inflammation and exacerbations. Despite its benefits, many doctors overlook testing or recommending vitamin D, highlighting the importance of patient advocacy. Pairing supplements with vitamin K2 may enhance calcium utilization and cardiovascular benefits.
