To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
I purchased it because of a vitamin d deficiency and it had 10,000. I have purchased another manufacturers cream and it smelled pleasant but didn't offer enough vitamin d. But this product smells rancid when applied. Maybe it was handled wrong and left in the heat or something but it smells bad. So I thought I would send an email to the one on the bottle for customer care at Biolabs and the email came back undeliverable because it doesn't exist. Also no info on the web for customer for a phone number. Seems odd but I will definitely be returning it and buying another manufacturers cream.
