Pharmaceutical Grade Supplement Studies

Pharmaceutical Grade Supplement Studies

Rachel here! As a follow up to my last blog post “Why Pharmaceutical Grade Supplements are Better Than Retail”, today I will be sharing a few studies to back up my claims!


A study published in the Journal of the International Society of Sports Nutrition compared the purity and accuracy of label claims of 12 retail-grade multivitamins with 12 pharmaceutical-grade multivitamins. The study found that the pharmaceutical-grade multivitamins had a significantly higher level of purity and more accurate labeling than the retail-grade multivitamins.

Another study published in the Journal of Dietary Supplements compared the absorption and bioavailability of calcium supplements in postmenopausal women. The study found that a pharmaceutical-grade calcium supplement had a higher bioavailability than a retail-grade calcium supplement, meaning that more of the calcium was absorbed by the body.

A third study published in the Journal of Clinical Endocrinology and Metabolism compared the effectiveness of a pharmaceutical-grade vitamin D supplement with a retail-grade vitamin D supplement in improving vitamin D levels in patients with vitamin D deficiency. The study found that the pharmaceutical-grade supplement was more effective in improving vitamin D levels than the retail-grade supplement.


My favorite pharmaceutical-grade Vitamin D 5000 + K:


A study published in the Journal of the Academy of Nutrition and Dietetics compared the quality control measures of pharmaceutical-grade supplements with those of retail-grade supplements. The study found that pharmaceutical-grade supplements had stricter quality control measures and were more likely to meet label claims than retail-grade supplements.

In conclusion, these studies suggest that pharmaceutical-grade supplements are generally of higher quality and more effective than retail-grade supplements. However, it is important to note that not all pharmaceutical-grade supplements are created equal, and it is still important to do your research and choose a reputable brand. Additionally, it is always recommended to consult with a healthcare professional (like me!) before starting any new supplement regimen.
