@llmartin I will leave you with one last tip that you can further research. Our bones, joints and tendons are impacted by psoriatic arthritis and need to be strengthen with calcium. You may be taking D3, but all of us also need vitamin K2.

Vitamin K2 takes the calcium out of the arteries and to our bones and reduces the plaque build up in the arteries. Our ancestors had plenty of K2 when animals were on pasture and they could get the helpful bacteria from the soil. Today, we get very little K2 in our food, such as dairy, since animals are fed in factories and not on pasture.

The natto I make has plenty of K2 so I do not need to supplement. My wife does take a K2 supplement, the MK-7 form that is derived from natto. ( I need to caution anyone on blood thinners with the interaction with K2. Consult your Doc before taking K2 if you are on blood thinners.)

There has been much research on K2 with the bones. They are beginning to research K2 with the tendons. I could tell a difference in joint pain and with having tendon flares when I do not have the natto. I buy fresh black soybean natto from NYrture that is in the Bronx and use it as my natto starter or backup supply.

The point is: Taking just D3 and calcium will get the calcium to the arteries, but only a small amount to the bones. K2 is needed to get calcium to the bones. Everyone needs strong bones, especially those with psoriatic arthritis. Also, research how our bones are in a constant state of rebuilding. Our bones rebuild about every 7 years. If they do not receive sufficient new calcium, they become brittle.
