The quality and safety of our products is of utmost importance to Rainbow Light. We have rigorous standards and processes in place to ensure careful selection of suppliers, tests of inbound materials and finished goods testing, in compliance with GMPs (Good Manufacturing Processes).
We take great pride in providing high quality, safe products to our customers. All of our tablets, capsules, softgels, gummies and powders are manufactured in compliance with Good Manufacturing Practices(GMPs) set forth by the FDA. GMPs are related to the manufacturing, packaging, labeling or holding of dietary supplements. Manufacturers are required to evaluate their products’ identity, purity, strength and composition. Other requirements deal with such matters as quality control, the design and construction of manufacturing plants, record keeping and consumer complaints.
Color variations are common in natural products. While Good Manufacturing Practices are employed at every level of production, including use of a “standardized recipe”, on occasion an herbal ingredient will have a color or taste variation due to seasonality, growing conditions etc. Some of Rainbow Light’s approved food and herbal ingredients are sourced from local farmers and are either Certified Organic or wild-harvested. A quality assessment is performed on each supplier and all materials are sampled and undergo a thorough inspection before being used in our products to ensure that these variations do not impact the overall quality of the finished product.
Epidemiological studies show that excessive levels of vitamin A, from either dietary or supplemental sources, has the potential to interfere with cells that produce new bone, stimulate cells that break down old bone and can interfere with the action of vitamin D, which helps the body maintain normal calcium levels.1 At the time of this publication, governing bodies reviewed all available evidence and found insufficient scientific support for changing the Upper Level of vitamin A. Supplemental levels of less than 5,000IU have not shown any detrimental effect on bone.
Some health care providers may advise consumers to be cautious about potential toxicity issues when using products containing vitamin A. Vitamin A is a safe and essential nutrient provided at less than 5,000IU in all Rainbow Light vitamin A containing products. The average intake from sources other than supplements is likely to be less than 3,400IU.1 So realistically there is very little risk of coming close to even the UL by combining a Rainbow Light supplement with the average American diet. In addition, Rainbow Light products often employ a combination of pre-formed vitamin A with beta-carotene, which is only converted to Vitamin A in the body as needed. (for more information see FAQ- “Vitamin A vs. Beta-carotene”) Keeping this in mind, Rainbow Light will continue to review the research and will reassess the current levels of vitamin A provided in our products if deemed scientifically rational.

The best time to take any supplement is when you remember to take it. Regular use is an extremely important factor in determining whether a supplement will work for you, especially for long-term ailments or symptoms, or to prevent disease and promote longevity. Rainbow Light’s supplements are very gentle on the stomach and can therefore be taken at any time with or between meals. Some experts recommend taking any supplement with a meal, when your digestion is most active, for maximum absorption and to lessen the possibility of gastrointestinal upset.
Tablets produced according to Good Manufacturing Practices's (GMP’s) adhere to USP (United States Pharmacopoeia) disintegration guidelines. These standards require that coated tablets disintegrate within a set amount of time following ingestion and take into consideration that there are many physiological factors impacting disintegration times.
Rainbow Light’s laboratory utilizes the USP disintegration test to ensure our tablets will dissolve in the gastrointestinal(GI) tract allowing the nutrients to be available for absorption. This procedure is carried out in an apparatus that mimics the actions of the GI tract during digestion. USP defines complete disintegration as “that state in which any residue of the unit, except fragments of insoluble coating or capsule shell, remaining on the screen of the test apparatus, is a soft mass having no palpably firm core.” The approved procedure utilizes specific apparatus and methods, and is slightly different for uncoated (30 minutes), film-coated(30), plain coated(45), hard gelatin(45) and soft gelatin capsules(45).
“Table top” methods involving vinegar and other acids are not a reliable test for determining disintegration. Simply dropping a tablet in a glass of water or vinegar solution does not properly simulate the temperature, pH conditions, and movement of the stomach and GI tract during digestion. The vinegar test is only appropriate for formulas that contain just calcium carbonate, and is not appropriate for food-based supplements-after all, you can't dissolve a piece of food in a glass of vinegar!
In 2005, Rainbow Light expanded our product line to include gummies, which are manufactured by our affiliate confectionery company Alinova, located in Colombia, South America. Alinova’s highly skilled technical management has 35 years of hands-on experience, and has been producing and exporting gelatin-based gummies from their Bogota facility since 1999. Currently, they export to the United Kingdom, Europe, Canada, Singapore, Peru, Venezuela and the United States.
Alinova is in full-compliance with Colombian food production regulations as well as specific requirements for exportation to other countries. Alinova follows the same GMP practices as US based food manufacturing facilities, and conforms to two of the highest global quality assurance programs for food safety and manufacturing: GFSI (Global Food Safety Initiative) and HACCP (Hazard Analysis and Critical Control Point). Rainbow Light thoroughly inspects and tests each batch of product prior to release into distribution.
Rainbow Light strives to provide the highest-quality ingredients in all formulations which allows us to uphold our commitment to environmental and human health concerns. We formulate all of our supplements to contain raw materials which are non-GMO, whenever possible.
Additionally, Rainbow Light has several products enrolled with the Non-GMO project and our values closely align in that we believe everyone deserves an informed choice about genetically modified organisms.
Rainbow Light’s label guarantee complies with the allergen labeling law called FALCPA (Food Allergen Labeling and Consumer Protection Act) that went into effect 1/1/06. If a product contains any ingredients which are derived from milk, egg, fish, crustacean shellfish, tree nuts, wheat, peanuts, and soybeans, it is clearly labeled.
The law does not mandate advisory statements such as if it is manufactured in a facility using one of the allergens. Gluten labeling is not mandated by FALCPA, but Rainbow Light includes a gluten-free reference in our guarantee unless trace amounts of gluten are present.
