Best for expert advice: Persona

Persona is a personalized subscription service that delivers vitamins and supplements monthly.
Each customer has to do an assessment, and the company says it works with doctors and professional nutritionists to find a combination of vitamins and supplements that meets each person’s needs.
Persona sells a variety of products, including:
- weight loss support supplements
- sleep supplements
- women’s multivitamins
- men’s multivitamins
- CBD supplements
The products do not have USP verification. The company says that doctors have approved its recommendations, and its ingredients have undergone multiple quality tests. Each product comes with a safety certificate.
The company’s process of personalizing an individual’s subscription starts with an online assessment. The assessment covers a person’s:
- age
- gender
- reasons for taking supplements, such as pregnancy, immunity concerns, or general health and wellness
- specific health concerns, from digestion to sleep and more
- dietary concerns
The company’s website states that it offers one-on-one expert advice. The company’s Medical Advisory Board comprises seven doctors and seven nutritionists.
The prices depend on the personalized plan a person chooses, but costs can range from $20–$100 per month.
