Made in the USA, Thera-D® vitamin D3 is our most recommended vitamin D supplement.  Thera-D is available in three strengths: 2000 international units (iU) (available here as a 180-day-supply for $24), 4000 iU (as a 90-day-supply for $24), and 6000 iU (as a 90-day-supply for $26).  In fact, Theralogix also offers the option for rapid correction (repletion) of vitamin D deficiency by shipping a bottle of higher dose vitamin D, followed by subsequent lower dose vitamin D (all of $24). 


Testing consistently shows a vast number of American adults having low vitamin D levels despite use of dairy products, despite regular sun exposure, and even despite low-dose vitamin D supplementation.  Hypovitaminosis D (significantly low serum vitamin D levels) has been found in association with greater risk of prostate, greater risk of bladder cancer, worse survival in prostate cancer, worse survival in bladder cancer, osteoporosis, depression, and many other chronic diseases.
