Helps with Symptoms of Rheumatoid Arthritis
Some early studies suggest that vitamin B5 may help with the painful symptoms of rheumatoid arthritis. One study found that people with Rheumatoid Arthritis may have lower levels of B5 in their blood than healthy people.
Lower levels of vitamin B5 were associated with the most severe symptoms of arthritis, including painful movements, stiffness, and inflammation.
It has been recorded that high doses of vitamin B5 can help with stiffness and pain in people suffering from Rheumatoid Arthritis. And taking B vitamin complex supplements has been correlated with lower levels of joint pain, enhanced muscle strength, and fewer symptoms associated with muscle or joint fatigue.
9. Aids in Immune Function 
Vitamin B5 helps to create antibodies that our immune system produces in order to defend us against potential threats.
These can include environmental and allergic responses, as well as fighting off parasites, bacteria, viruses, the common cold or flu, and toxins.
