Quality Ingredients:

Most of these practitioner multivitamin brands use quality ingredients in the standard multivitamin components, such as the methylcobalamin form of Vitamin B-12, the D-3 form of Vitamin D, and a mix of various forms of minerals utilizing the amino acid chelate or Krebs cycle form of the mineral for greater absorption.

Maximum Vitality® includes a number of expensive ingredients not included in other practitioner multivitamins. These include Coenzyme Q10, trans-Resveratrol, alpha- and r-lipoic acid, the gamma tocopherol and tocotrienol forms of vitamin E, and proanthocyanidins from grape seed. Many of the ingredients in prophylactic doses are included to balance and enhance overall health. These dosages are not intended to cure disease or patients with serious deficiencies.

See Quality at RSLabs for more information.

Value

With the lowest price per month compared to lesser, 4-Star-rated multivitamins, patients are pleased in the choice of Maximum Vitality as the patient greatest value among practitioner multivitamins.

Compliance

Compliance is perhaps the most critical confounding factor. For if the patient is required to follow too difficult a dosing protocol, and ends up not taking their multivitamin, then no matter how high the quality, the unused supplements provide no value. Maximum Vitality provides the greatest opportunity for compliance in this practitioner multivitamin comparison with a dose of only 4 tablets per day.

Independent Rating

Confirming the sophisticated formulation and quality ingredients, Lyle MacWilliam’s 2017 6th edition of the Comparative Guide to Nutritional Supplements assigned RS Labs® Maximum Vitality® the only top 5-Star rating among practitioner multivitamin brands. Past editions show Maximum Vitality rating 5-Stars in the 2014 and 2007 editions, and 100 in an update to their 2003 edition, the only practitioner brand multivitamin to demonstrate ongoing enhancements to maintain a top rating for over 14 years.
