Same here, Vitamin D deficient and also for one of the B vitamins. A few years I ago I was completely deficient in folate too (discovered incidentally on a blood test for something else) so had to take strong one for four months consistently to build levels back up and still continue to take a standard folic acid supplement now. Hers are insanely overpriced. Such a gimmick.I'm deficient in Vitamin D and need to take a daily supplement.
Dr D €12.99 for 60 1000iu
Aldi less than €3 for 180 1000iu
So over 4 times the price for a third of the quantity.
That's daylight fuckin robbery nothing less
Also just to say, I don't advocate just taking vitamins willy nilly. Supplements and vitamins are way over hyped and often unnecessary if you maintain a balanced diet. However, couldn't rectify mine with diet unfortunately.
