Private Labeling Supplements: Ingredients, Testing & Certifications

Explore ingredient sourcing, testing protocols, and certification standards for our top selling products.

Many health, well-being, and beauty business owners and executives are considering adding supplements to their shelves for good reason. The supplement industry is growing exponentially, creating an opportunity to meet customers’ needs and expand your business in new ways.

However, inventory and pricing can be concerns, making private-label supplement brand partnerships particularly attractive to many decision-makers. Private labeling allows companies to create their own branded line of supplements based on the buying patterns of their customer base.

They leverage the relationships built around the brand with a trusted supplement manufacturer’s quality, consistency, and certifications. Consumers are increasingly knowledgeable and discriminating about the supplements they purchase.

This is why medical professionals and business owners like pharmacists, wellness coaches, and retailers should research supplement manufacturers carefully before partnering with one to create a private label brand.

This guide provides an in-depth look at the top-selling supplements offered by DaVinci® Laboratories, including ingredients, third-party testing, and certifications—all major considerations for anyone deciding on a private-label supplement partnership.

A GROWING OPPORTUNITY IN SUPPLEMENTS

supplement sales stat

In 2023, 74% of American adults took some form of dietary supplements, and 55% took supplements regularly, according to the Council for Responsible Nutrition.

The market is still growing. Supplement sales topped $68.20 billion in 2023, and forecasters with Future Market Insights predict it will grow to $163.66 billion by 2033.

New markets of health-conscious consumers are buying more of these products to support healthy, normal functions of the body.

According to the National Library of Medicine, around 600 supplement manufacturers and about 4,000 products existed in 1994.

Today, according to the American Medical Association, there are around 90,000 products. This rapid growth has created huge opportunities for healthcare practitioners and business owners that want to build their own brand while helping people maintain a healthy lifestyle.

Private labeling with the right supplement manufacturer allows you to sell proven, top-selling supplements to discerning consumers while also building brand loyalty.

Types of Supplements for Private Labeling

One of the first steps to creating a private-label supplement line is understanding the available formats. Some provide more convenience for users, while others are best chosen based on absorption rates and bioavailability.

You might consider different types of supplements for various customer segments. For ex- ample, a company focusing on children’s health may wish to add more chewables and liquids, as capsules may be difficult to swallow.

Businesses that want to incorporate supplements into a smoothie bar may focus on powders and liquids. Businesses and brands may also wish to create a unique product mix of various types.

CHEWABLES

Chewable supplements can be a soft chew or a chalky tablet, depending on the formula. Either way, they are designed to be consumed by chewing and swallowing without water. They can feature a variety of flavors, making them an easy, palatable choice for adults and children alike.

LIQUIDS

Supplements are also sold as liquids, an attractive alternative for people who avoid large capsules. Liquid supplements can be consumed with or without food, although they are frequently mixed with water, juice, or smoothies. Liposomal liquid supplements are also popular for their increased absorption rates.*

POWDERS

Often used in smoothies, powder supplements are another popular supplement type among private label brands. Protein mixes are the most popular powder supplements as protein helps repair muscle tissue and creates enzymes.*

CAPSULES

Capsules remain the most popular offering for supplements, as the format can offer easy dosing while maintaining a high level of quality.

TABLETS

Like capsules, tablets are an- other traditional method of delivery for supplements. Tablets, which are compressed powder, can be sized to make them easier to swallow with water.
