Key Benefits and Actions*

  • Comprehensive daily multivitamin featuring plant-powered phytonutrients
  • Bioavailable nutrients support healthy aging, normal detoxification, energy, and vitality
  • Antioxidant support for immune health

Optimal Multivitamin by Seeking Health is a complete daily multivitamin and mineral supplement containing more than 50 nutritional ingredients, all in a special base of green superfoods plus a fruits and vegetable blend. There are no gimmicks, no shortcuts, only researched nutrients that help provide the body with what it needs to support optimal function and overall health.*

Each ingredient in this optimized multivitamin formula is chosen with its absorption, competitive relationship with other nutrients, allergenic potential, and long-term safety taken into account. If the body is unable to absorb the nutrients in a multivitamin, they cannot be utilized for optimal health. Certain nutrients such as beta-carotene, vitamin C, vitamin E, and a well-rounded B vitamin complex are included in high-potency amounts because of the vital roles they play in supporting the body’s antioxidant defenses, energy production, maintenance of healthy blood cells, nervous system health, healthy endocrine function, and more. Minerals and trace elements are provided in the well-tolerated and bioavailable forms, and the whole formula is encapsulated in easy-to-digest vegetarian capsules that are easier to break down than compressed tablets.*

Optimal Multivitamin is iron-free, as most adults do not require iron supplementation. For a specialized multivitamin for children, consider Kids Multivitamin. For a chewable alternative, try our Optimal Multivitamin Chewable.*

1. Who is Optimal Multivitamin intended for?

Optimal Multivitamin is intended for adult individuals who wish to promote health by supporting adequate daily intake of nutrients. A large percentage of the U.S. population fails to meet daily requirements or adequate intakes for micronutrients. Many adults fall short in(1):

  • Potassium by 100%
  • Vitamin D by 94%
  • Choline by 91%
  • Vitamin E by 88%
  • Vitamin K by 66%
  • Magnesium by 52%
  • Calcium by 44%
  • Vitamin A by 43%
  • Vitamin C by 38%

Taking a daily multivitamin can help to support good health by supplying micronutrients. For those in excellent health, employing the pulsing method may be beneficial.

Optimal Multivitamin is a great product for anyone looking for potent, comprehensive, and bioactive support for methylation, healthy aging, or general wellness.*

Always talk to your doctor before considering the use of this product, especially if you have health conditions or diseases that need to be addressed.

2. How do I take Optimal Multivitamin?

As a dietary supplement, adults take 8 capsules daily or as directed by a healthcare practitioner. For those new to this product, start with a small dose and work your way up to the recommended serving size, or consider the pulsing method for staggering doses.

This product is best taken with meals and may be taken in divided doses. Avoid taking within 5 hours of bedtime as it may interfere with sleep.

If you struggle to swallow capsules, they may be pulled apart and sprinkled on food or in juice.

We expect our product to be free of genetically modified material. We are currently working on conducting complete product testing to verify that there is no genetically modified ingredients in the finished product.

7. Is Optimal Multivitamin vegetarian/vegan?

Optimal Multivitamin is vegetarian. The vitamin D3 is derived from lanolin from sheep’s wool, so this product is not vegan.

8. What are the possible interactions or side effects of using Optimal Multivitamin?

Side effects of this formula may include, but are not limited to:

  • Anxiety
  • Restlessness
  • Flushed skin
  • Mild rash

  • Muscle pain
  • Upset stomach

If you believe that you are experiencing any adverse reactions, please see your healthcare professional immediately and discontinue use. Each individual may react differently to any product or supplement. We always recommend that you consult with your healthcare professional prior to considering the use of Optimal Multivitamin or any supplement.

9. Why doesn’t Optimal Multivitamin contain iron?

Many adults don’t require iron supplementation, so we chose to formulate this product without it, making it more accessible for adults in general. Iron also competes with calcium absorption, making it best when taken 2 hours apart, if needed. If you are looking for iron support, consider the Optimal Iron Chewable or Optimal Iron Plus Cofactors.
