Which Rainbow Light vitamin is best?

Eating a well-balanced diet is the cornerstone of maintaining good health. The physical and mental benefits of proper nutrition are well-known, but even the healthiest people can struggle to get all the nutrients they need from food alone. That’s why supplements and vitamins can be helpful, and have become so popular.

Founded in Santa Cruz, California, in 1981, Rainbow Light is committed to holistic wellness by offering a line of gluten-free, non-GMO and eco-friendly vitamins. The Rainbow Light Men’s One Multivitamin is best because it helps provide essential nutritional support.

What to know before you buy Rainbow Light vitamins

Category of vitamin

Rainbow Light makes dozens of vitamins and supplements, but its most popular are:

  • Multivitamins: These provide the daily allowance of most essential vitamins and nutrients in one serving. A multivitamin is your best bet if you only want one vitamin.
  • Vitamin C: This essential vitamin strengthens the immune system, helps repair body tissue, and helps maintain healthy bones and teeth.
  • Vitamin D: Many people are vitamin D deficient. Vitamin D strengthens your immune system, boosts mood, supports muscle growth and can reduce the risk of certain diseases.
  • Immune support: Rainbow Light has a series of vitamins designed to boost immune health. They contain combinations of vitamins C and D, zinc and other essential nutrients.

Rainbow Light also offers probiotics, minerals and prenatal vitamins.

Vitamin form

Gone are the days when all vitamins came in pill form. Not all Rainbow Light products are available in all forms, but those forms include:

  • Tablet: These are like traditional pills and are composed entirely of the compound. They can also be split and crushed. They can easily accommodate high dosages and tend to have a long shelf life.
  • Capsule: They’re similar to tablets, but the compound in capsules is encased in a shell. They can’t be as easily split or crushed, but capsules have higher bioavailability — that is, they can be more easily absorbed into the body.
  • Chewable: Great for kids and those who have trouble swallowing pills, chewable vitamins are easy to eat and digest. But they often contain smaller doses of vitamins.
  • Gummy: Much like chewable vitamins, gummies were designed to taste better and are often easier to digest, but they typically don’t contain as many nutrients. They can be good for those who want to get in the habit of taking vitamins.
  • Mini-tablet: For those who struggle to take full-size pills, Rainbow Light makes some vitamins in mini-tablet form. These offer the same nutrients but have more pills per serving.

What to look for in quality Rainbow Light vitamins

Life stage

Preexisting conditions or prescription medication can influence what vitamins you should take or avoid, so always check with your physician. However, age also affects what nutrients your body requires, so Rainbow Light makes vitamins designed for adults, kids, teens and those over 50.

Dietary preferences

For those on a vegan or vegetarian diet, Rainbow Light makes some vitamins that contain no animal products.

How much you can expect to spend on Rainbow Light vitamins

Since the type and quantity of vitamins can vary, it’s best to consider the cost per pill. These vitamins range from 17-30 cents per pill, depending on their ingredients. Multivitamins or capsules with more than one compound are more expensive than a single-ingredient vitamin.

Rainbow Light vitamins FAQ

Why can color and taste vary per batch?

A.  Certain herbal ingredients vary in color and taste due to growing conditions and the season of the year. Rainbow Light conducts a quality inspection of every ingredient before it’s used, so any variation in color or taste won’t affect quality.

When should I take my vitamins?

A. Always follow the instructions on the package, which can vary depending on the vitamin. However, Rainbow Light vitamins are easy on the stomach, so most can be taken at any time of the day. What’s most important is that you are consistent. Taking your vitamins with food is also helpful because it maximizes absorption.
