Of course adequate vitamin D3 softgel supplementation helps, for the simple reason that it almost always effectively raises the blood level of vitamin D, thereby maintaining its sufficiency. Those who struggle with such simple logic will struggle hard in life. Elderly people or those with heavy sunlight exposure or unhealthy kidneys or magnesium deficiency can exceed the target blood range of vitamin D even with 5K IU of vitamin D3 per day. I consider anything over 60 ng/mL to be in a strict excess of the target range.
