Both Persona Nutrition and Care/of use an online health assessment to curate a daily supplement routine tailored to your needs. However, Persona Nutrition offers a wider selection of products and includes free consultation with their team of nutritionists, which may be an important consideration for some.
On the other hand, Care/of provides more detailed information about the sourcing of all ingredients they use, as well as the research behind each formulation. Some Care/of products can also be purchased individually at Target, which may be preferable for those who don't want to commit to a monthly subscription.
