I've been buying some vitamins and supplements from Higher Nature for years, especially the Vit C Powder (previously called 'buffered') and their Vit D spray, I love them and they've kept me alot healthier than before I started using them. I recently re-ordered those plus others; I get the membership as the discounts are really good if you can order alot at one time (I get a year's or 6 months' worth). The queries I had about whether some new vitamins would be compatible with my modern blood thinner medication were answered (one yes, one not), and the package was sent out that day, arrived a few days later. Excellent products and service.
