My trusted, go-to source for all supplements - no gimmicks, no nonsense, good advice and great service & value. Been taking D3 & K2 for a couple of years now - recently had blood tests & despite having a lot of symptoms of menopause, my Vit D levels were normal. I know I don't get enough exposure to sunshine (office-worker) so think vit D is essential for me.. Love knowing exactly what's in it and where it comes from & why.. 100% happy ?
