Vitamins & Supplements Buying Guide
Most of us get essential vitamins, minerals, and nutrients from the foods we eat. But certain health problems and the natural aging process can affect the body’s ability to absorb nutrients and effectively use them. The right vitamins and dietary supplements can support you or your loved one’s health and reduce the risk of vitamin and nutrient deficiencies.
How Do I Know If I Need Vitamins and Supplements?
Vitamins and supplements support people who aren’t able to optimize nutrition through food alone. Vitamins and supplements come in various types and formulations. You may need these supplies if you or your loved one are living with:
Liver failure
Kidney disease
Malabsorption syndrome
Anemia
Diabetes
Inflammatory bowel disease (for example, Crohn’s disease or ulcerative colitis)
Vitamin D deficiency
Prostatitis or benign prostatic hyperplasia (BPH)
Arthritis (for example, osteoarthritis, rheumatoid arthritis, or gout)
Mood disorders (for example, depression or generalized anxiety disorder)
Seasonal affective disorder (SAD)
Osteoporosis
Alzheimer’s disease or another type of dementia
Sometimes, vitamins and minerals are used to support pregnancy. For example, you might opt to take a prenatal vitamin if you’re currently pregnant or trying to get pregnant.
Vitamins and Supplements: How Do I Choose?
Choosing the right vitamins and supplements can be challenging. There are dozens of brands, which makes shopping tricky. Thankfully, following a few basic guidelines can help.
“Vitamins and supplements aren’t regulated like medications,” explains James Wilkinson, CEO of Balance One Supplements. “This lack of rigorous oversight means you need to exercise discernment. It’s vital to investigate and choose brands known for their high quality and transparency.”
Here are Wilkinson’s tips for doing that:
Buy products that engage in third-party testing and adhere to Good Manufacturing Practices (GMP). Wilkinson says these endorsements “indicate products are free from impurities and faithfully contain the advertised ingredients at the claimed levels.”
Check product labels for clear ingredient sourcing (E.g. Where did the ingredients come from?)
Look for fillers and additives, like gelatin and cellulose. (The more fillers a supplement contains, the less likely it is to work as stated)
Make sure the supplement label lists specific ingredient quantities
Look for products with clear dosage information
Read customer reviews
Visit the manufacturer’s website. Wilkinson says “reputable firms provide info on their research and development practices.”
The vitamins and supplements we sell at Carewell meet all of the above guidelines. We’re happy to answer your questions and make product recommendations if you need help.
Before Taking a New Vitamin or Supplement Do This
Vitamins and supplements can help support your health goals, but you should speak with your doctor or healthcare provider first.
“Discussing supplement use with your doctor is crucial for several reasons,” says Krutika Nanavati, RDN, a registered dietitian nutritionist. “First, you need to identify potential interactions. Certain supplements can interact with the medications you take, causing adverse side effects. Second, you need to rule out underlying medical conditions. Some nutrient deficiencies indicate underlying health problems requiring treatment. Third, you need personalized recommendations. Your doctor can recommend supplements based on your individual needs and health history.”

Herbal supplements are made from plant-based ingredients, like seeds, stems, leaves, and flowers. They’ve been used for thousands of years all over the world to manage everything from inflammation and stomach problems to headaches and sore throats.
Herbal supplements come in various forms, including capsules, teas, oils, and ointments. Instead of increasing nutrient levels, they address specific symptoms or medical issues.

Iron Supplements
Iron is an essential mineral that the human body needs to function. It plays a key role in the production of hemoglobin, a protein in red blood cells that carries oxygen. Iron is found in many foods, but not everyone absorbs enough of it to maintain good health.
Though anyone can experience iron deficiency, it's more common in women than men. If you aren’t able to maintain adequate iron stores through diet alone, your doctor might recommend iron supplementation.
Best For:
Pregnant people
People who experience heavy periods
Those who take iron-depleting medications (for example, prescription antacids)
People with certain blood disorders, like sickle cell disease
Those who have undergone gastric surgery
Price: $5.95 - $89.10
Price: $3.92
Joint Health Supplements
Joint health supplements promote joint function and mobility. They contain ingredients like glucosamine, curcumin, and omega-3 fatty acids. Nutrients that reduce inflammation, relieve pain, and prevent cartilage breakdown.
With a healthy diet, exercise, and other lifestyle changes, these supplements can help you stay active. That means less sitting and more time visiting friends and grandkids.
Best For:
People with arthritis
Those who experience chronic joint pain and/or stiffness
People who can’t take non-steroidal anti-inflammatory drugs (NSAIDs)
Folks who suffer from limited mobility because of joint pain or cartilage breakdown
Prostate Support
Prostate support supplements are formulated to reduce the risk of prostate problems, like benign prostatic hyperplasia (BPH) and prostate cancer.
These supplements often contain ingredients like saw palmetto, selenium, and zinc. Saw palmetto is thought to relieve BPH symptoms like increased urination and weak urinary flow, while selenium and zinc may support prostate function and help protect against prostate cancer.
Best For:
Men with a family history of BPH and/or prostate cancer
Men experiencing urinary symptoms, such as increased urination or weak urinary flow
Men suffering from prostatitis (prostate inflammation)
It’s important to remember that taking a prostate supplement can’t cure or treat prostate disease, nor will it prevent prostate problems. However, it may provide peace of mind and help support prostate gland function.

Prenatal Vitamins
Prenatal vitamins contain vitamins, minerals, and nutrients necessary for a healthy pregnancy. Specifically, they include folate (a B vitamin) that supports the growth and development of a baby.

Women of reproductive age who are sexually active

When taken daily as part of a healthy lifestyle, multivitamins may offer various benefits, including improved nutrition and chronic disease prevention. Still, they aren’t a substitute for eating a balanced diet, exercising regularly, and getting good sleep.
Best For:
Pregnant people
People trying to get pregnant
People 50 and older (aging affects the body’s ability to absorb adequate nutrients from food alone)
Those who eat vegan or vegetarian diets, as nutrients like vitamin B12 are only found in animal proteins
Price: $2.16 - $20.29
Vitamins & Supplements - Commonly Asked Questions
1) Should I consult with my doctor before taking vitamins and supplements?
Yes. Wilkinson says that before starting any new vitamin or nutritional supplement, it’s essential to consult with your doctor. “Their personalized advice –– especially concerning your health history, current medications, and specific nutritional needs –– is invaluable. Supplements may interact with other medications you’re taking, have contraindications, or provide unnecessary given your dietary intake and overall well-being. A consultation will help identify specific deficiencies needing attention and ensure the safety of any supplement for you.”
2) Can vitamins and supplements take the place of good nutrition?
Vitamins and supplements may support your health and well-being, but they aren’t a substitute for eating a nutritious, balanced diet. “Remember: supplements are meant to complement –– not replace –– your diet,” Wilkinson says. “Maintain good health by ensuring a balanced diet. Use supplements only to bridge any nutritional gaps as necessary.”
3) Does a supplement’s price indicate its quality and efficacy?
Not necessarily. Nanavati recommends comparing prices when doing your research. “Don’t assume expensive equals better quality,” she says. Wilkinson agrees, noting that “quality varies significantly among brands, often reflected in price. However, lofty prices don’t always guarantee top-quality products.” At the end of the day, “transparency reigns supreme ––reputable firms boast about their offerings by providing thorough information on the research and development that informs their formulations.”
