A note on personalized vitamins

Care/of is a subscription service that offers personalized vitamins, which are supplements customized for you based on the results of a health questionnaire.

Because the questionnaire doesn’t replace the guidance of a qualified health professional, it’s important to talk with a doctor or registered dietitian before taking any new supplements.

Care/of is a personalized vitamin subscription service that delivers a monthly supply of supplements right to your door.

The company offers a wide variety of products geared toward adults and provides recommendations based on your answers to an online questionnaire.

This article provides a comprehensive review of Care/of, including how it works, the products it offers and their effectiveness, and the service’s potential downsides.

You may be wondering why a vitamin subscription service would be better than simply purchasing your supplements at the store or online as needed.

First, subscription services are personalized. You will receive recommendations based on your answers to a health questionnaire that asks about your goals, your current routine, and your health status.

However, although this is helpful, the most accurate way to determine whether you need supplements is through blood work and a dietary and medical review with a healthcare professional.

Vitamin subscription services are also convenient.

The vitamins you select from Care/of are sent in daily packs, so you won’t receive any bottles or boxes. Just tear open your daily pack each day and take the vitamins inside. Subsequent orders will automatically ship out, so you don’t have to worry about reordering.

However, vitamin subscription services are often more expensive than one-off vitamin purchases, and there’s no guarantee you won’t experience interruptions. For instance, certain items may be out of stock when it’s time for you to refill, or shipping may be delayed.

Additionally, while personalized quizzes are helpful, they aren’t an adequate substitute for nutrient or hormone testing — so the recommendations you receive may not necessarily reflect the nutrients you may need.

Care/of is a vitamin subscription company that provides personalized supplement recommendations and delivers them straight to your door.

For added convenience, the daily supplements come packaged in individual envelopes so you don’t have to worry about opening multiple bottles.

The goal of Care/of is to make purchasing supplements easier by taking the guesswork out of choosing which ones to take.

How it works

To get started, customers complete a quick health assessment on the company’s website.

In addition to your sex and age, the questionnaire asks about your overall health, including the following questions:

  • Have you taken vitamins in the past?
  • What should we explore? (This question refers to any health concerns you have, such as those about digestive issues, low energy, or heart health)
  • How many servings of fruits and vegetables do you eat most days?
  • Do you smoke?

Using this information, Care/of recommends three to four supplements, which you can choose to purchase or replace with other products.

It’s important to note that only the types of supplements, not the dosages, are personalized. Therefore it’s best to confirm the appropriate dosage with a healthcare professional.

Once your products have been selected, you’ll receive a 30-day supply in the mail. Monthly refills are shipped automatically, and you can pause the service at any time.


Care/of is a vitamin subscription company that delivers personalized supplements. Product recommendations are based on an online health quiz, but you can easily adjust your order at any time.

Care/of offers a wide selection of products that are categorized as either vitamins or powders.


Care/of offers a wide selection of vitamins, minerals, and other dietary supplements:

  • Letter vitamins. These include a B-complex, as well as single vitamins like vitamins C, D, and B12.
  • Multivitamins. This category includes a prenatal vitamin and multivitamin options.
  • Minerals. The company currently offers calcium, iron, magnesium, and zinc.
  • Herbs. Several herbal supplements are available, including elderberry, ashwagandha, garlic, and milk thistle.
  • Probiotics. Care/of offers Probiotic Blend, a probiotic that contains three beneficial strains of bacteria.
  • Specialty. These include omega-3s, vegan collagen boosters, keratin, astaxanthin, and an adaptogenic mushroom blend.


Care/of also offers several powders:

  • Collagen. Care/of’s bovine collagen powders come in four flavors: matcha, lemon passion fruit, vanilla oat, and unflavored.
  • Protein. Whey and plant-based protein powders are available in chocolate or vanilla.
  • Boosts. Boosts are powders that can be mixed with your favorite protein powder or beverage. Current offerings include creatine, electrolytes, maca root, a fiber supplement with chia and flax, and Superberry, which is high in antioxidants.
  • Quick Sticks. These single-serving powders are easily mixed into water and marketed for specific health concerns, including digestion and low energy. They contain a mix of micronutrients, herbs, and other compounds, such as probiotics.

Care/of offers a wide variety of products, including letter vitamins, multivitamins mineral supplements, herbs, probiotics, collagen, protein powders, Boosts, and Quick Sticks.

Care/of strives to provide supplements featuring the most effective form of each ingredient.

For example, rather than folic acid, which studies show can accumulate in the bloodstream and may be linked to adverse effects, Care/of’s folate supplement contains methylfolate — a form that is found naturally in food and doesn’t lead to unmetabolized folic acid in the bloodstream.

Research also suggests that methylfolate may be more effective at increasing folate concentrations in red blood cells (1).

However, Care/of does have room to improve some of its ingredients. For example, its magnesium supplement contains magnesium hydroxide, which research shows is not as well absorbed by the body as other forms, such as magnesium citrate (2).

The company seeks out ingredients that are sustainably and ethically sourced and tests each product at three points during manufacturing.

Care/of’s products are made in facilities that adhere to the current good manufacturing practices, a set of quality and safety standards put in place by the Food and Drug Administration.

According to the company’s website, products are tested multiple times throughout manufacturing, and final products are tested by third-party labs. This ensures that each supplement contains what is stated on the label.

However, Care/of products are not third-party certified. In addition to ensuring a product’s purity and potency, third-party certification is considered a gold standard and goes a step beyond third-party testing by confirming safe manufacturing and storage practices.


Care/of’s products are made with high quality, sustainably sourced ingredients. The supplements are tested multiple times throughout manufacturing, including by third-party labs.

To assess the benefits and effectiveness of ingredients, all of Care/of’s products are graded using the following scale:

  • Traditionally used: history of use in traditional or herbal medicine
  • Limited research: very little scientific evidence available
  • Emerging research: limited, recent evidence available
  • Good research: limited, high quality evidence is available
  • Strong research: supported by several high quality studies
  • Very strong research: supported by several robust studies, as well as expert consensus

In addition to listing the grade, each product page contains a summary of the related available evidence and a list of studies for further reference.

You can also dig into the company’s research library, which details the scientific research available to support the potential benefits and uses of each product.

It’s important to review the grades and research available for each product, as some health claims may not be as well supported as others.

For example, the Chill Factor Quick Stick is graded as “emerging research,” as it has only one study that supports the ability of its main ingredient — gamma aminobutyric acid (GABA) — to reduce stress (3).

On the other hand, the Extra Batteries Quick Stick is graded as “strong research,” as it cites several studies that support the effectiveness of the product’s main ingredients like caffeine.

Overall, when choosing supplements, make sure to look for those with a “strong research” or “very strong research” grade. You can find each product’s grade under the benefits tab on the product page.


While Care/of’s online questionnaire asks some health-related questions, it doesn’t provide a comprehensive medical history.

As a result, you may be recommended a product that interacts with a medication you’re taking or exacerbates a preexisting health condition.

Additionally, without blood work to confirm what your body needs, you may also be taking unnecessary nutrients or not enough of them.

For example, if you have a vitamin D deficiency, 1,000 IU (found in Care/of’s vitamin D supplement) is likely not a high enough dose to treat low or deficient levels.

In particular, many herbal supplements are not recommended for children or people who are pregnant or breastfeeding.

Overall, it’s best to talk with a healthcare professional before starting a new supplement regimen.


Care/of’s products are graded on a scale based on the strength of the available research. Look for products with a “strong research” or “very strong research” grade, and check with your doctor before taking new supplements.

The price of a monthly Care/of subscription varies based on the type and number of supplements selected.

Products range in price from $5–$32 for a 30-day supply, with free shipping on orders over $30.

The service ships to all 50 states and certain addresses in Canada and U.S. territories. However, there’s a $6 handling fee on all international orders.


The price of your Care/of subscription will depend on the type and number of products you receive. Shipping is free for orders over $30.

Care/of is a great fit for anyone who needs guidance on which supplements to buy. The personalized quiz will offer several recommendations that you can stick to or swap out as needed.

Still, proceed with caution and know that it’s always best to get supplement advice from a healthcare professional.

Care/of’s daily packs are also a good option for anyone who dislikes the hassle of opening various bottles or filling a pill organizer each week. They offer an easy and convenient way to take your vitamins. The daily packs are also helpful for people who travel often.

Finally, Care/of is an ideal solution for people who don’t want to worry about buying more vitamins when their supply starts to get low. The service will automatically send a new shipment every 30 days.


Care/of may be a good fit for you if you’re looking for recommendations about which supplements you need or if you want the process of ordering and taking vitamins to be as convenient and streamlined as possible.

Care/of’s reviews are overwhelmingly positive, with many customers noting that the vitamins make them feel great, that the prices are fair, and that customer service is really easy to work with when there is a problem.

However, negative reviewers say that sometimes shipping was so delayed that they were out of their vitamins for days, that Care/of’s more expensive vitamins didn’t seem to offer any advantages over less expensive brands, and that the daily packs contained too many pills.


Most Care/of reviews are positive, but some reviewers say that shipping can be delayed, the packs contain too many pills to take each day, and that they didn’t notice a big difference between Care/of and other brands.

While Care/of isn’t the least expensive vitamin subscription service, it offers one of the widest product selections and has the lowest free-shipping threshold of the three most expensive services.

However, unlike Persona and Hum Nutrition, Care/of doesn’t include access to a registered dietitian or another health expert.


Care/of is reasonably priced and offers a wider variety of products than other vitamin subscription companies. However, it doesn’t offer access to a health expert or dietitian.

Is Care/of more expensive than other subscription vitamin services?

No. It is roughly the same price as major competing services such as Persona Nutrition and Hum Nutrition. Prices for Care/of products range from $5–$32 per month.

A less expensive vitamin subscription service to consider is Nurish by Nature Made, which has prices ranging from $4–$15 per month.

Does Care/of offer a free trial?

No, Care/of doesn’t offer a free trial. However, they do offer a full refund within 30 days of your first order if you’re not satisfied.

What are the 5 most important vitamins?

The most important vitamins or minerals to supplement will vary significantly from person to person. However, here are five that may be beneficial to a large number of people:

  • Vitamin D. Vitamin D helps your body absorb calcium, and may also play a role in immune health and mood support. According to some research, most people don’t consume enough vitamin D-rich foods (4, 5).
  • Omega-3s. Omega-3 fats (found in foods like salmon and flaxseed) offer anti-inflammatory benefits and support brain and heart health, but most adults don’t get enough through diet alone (6).
  • Magnesium. According to a large nutritional survey, nearly 80% of adults in the United States don’t consume enough magnesium. Your body uses this mineral for more than 300 distinct purposes (7, 8).
  • B vitamins. Vitamins B6 and B12 are among the most common deficiencies, according to one 2017 study (9).
  • Vitamin C. Multiple studies have shown that many people in the United States don’t get enough vitamin C through their diets, so increasing intake through food and supplementation can be helpful for many (10, 11).

Zinc and folate are other common deficiencies, but again, blood work is the best way to find out which vitamins and other nutrients you may need to supplement.

Should I take my vitamins in the morning or at night?

For the most part, when you take your vitamins is a matter of personal preference.

I actually take my vitamins at lunchtime because taking them on an empty stomach makes me really nauseous — and that’s not something I even want to risk at the start of my day. Some people take their vitamins with the largest meal of the day for the same reason.

However, some supplements are best taken on an empty stomach, such as iron (which also should not be taken at the same time as calcium). It’s best to consult the directions on the bottle for each individual supplement.

However, if you’re profoundly deficient in a vitamin or mineral, you should speak with a healthcare professional or dietitian about the best timing to maximize nutrient absorption.

Care/of is a vitamin subscription service that provides personalized recommendations based on an online questionnaire.

Each product is made with high quality ingredients and graded based on the strength of available research. Additionally, final products are third-party tested to ensure purity and potency.

If you’re interested in trying a personalized vitamin subscription, Care/of is an excellent choice. Just make sure to talk with a healthcare professional before placing your order.
