About the Brand/Manufacturer
TruNature is a supplement brand developed for Costco Wholesale, one of the largest retail companies in North America. The brand focuses on affordable, easy-to-use health products that support digestion, heart function, and general wellness.
The products are made in the United States under Costco’s strict quality and safety standards. Manufacturing also follows Good Manufacturing Practices to ensure each batch meets consistent quality levels before reaching customers.
TruNature has built recognition mainly among Costco shoppers due to its accessible pricing and wide availability. However, it remains less visible outside Costco stores since it does not have an official website or direct customer service platform. This limited online presence makes it harder for customers to verify product details or seek support directly from the manufacturer.
That said, there’s also no clear money-back guarantee policy.
How Does TruNature Advanced Digestive Probiotic Work?
TruNature Advanced Digestive Probiotic works by adding helpful bacteria to the digestive system. These bacteria support balance in the gut and help limit the growth of harmful microorganisms that can cause bloating or irregular digestion. Each capsule provides 10 billion live cells and 12 probiotic strains that aim to maintain digestive comfort and support normal bowel movement.
The product also contains xylooligosaccharides, a natural prebiotic that feeds the good bacteria in the gut. This helps the probiotics grow and stay active, improving their ability to support digestion and immune health.
The Alimentary Pharmacology and Therapeutics journal published a review showing that certain probiotics can ease symptoms of irritable bowel syndrome (IBS) and other digestive problems. The findings revealed that probiotics may help reduce abdominal pain, bloating, and diarrhea, especially in people taking antibiotics. The review also confirmed that probiotics are generally safe for adult use [1].
TruNature Advanced Digestive Probiotic Ingredients: Are They Safe & Effective?
Here are the key ingredients found in TruNature Advanced Digestive Probiotic, along with what each one does and how research supports their potential digestive and immune benefits:
1. Lactobacillus acidophilus
Lactobacillus acidophilus is a well-known probiotic strain naturally found in the intestines. It helps break down food and improves nutrient absorption. As documented in our SugarMute Review (another supplement containing this ingredient), this strain also supports the growth of beneficial bacteria and limits harmful ones that can cause digestive discomfort.
The Journal of Microbiology and Biotechnology published a review on Lactobacillus acidophilus, a probiotic known for supporting gut health. It explained how this bacteria survives stomach acid, helps digestion, improves immunity, and is used in many probiotic supplements and foods for its health-promoting properties. The study also highlighted future opportunities for improving probiotic quality and effectiveness [2].
2. Bifidobacterium lactis
Bifidobacterium lactis is a beneficial bacterium that supports immune strength and digestion. As documented in our WOWMD M50 Menopause Essential Review (another supplement containing this ingredient), it helps maintain a balanced gut environment and may reduce occasional bloating or irregular bowel movements.
The Frontiers in Nutrition journal published a review on Bifidobacterium lactis, a probiotic known for improving digestion and bowel movement. The study explained that it helps strengthen the gut lining, supports faster digestion, reduces constipation, and protects against harmful bacteria. It also helps balance the immune system and promotes better digestive health [3].
3. Xylooligosaccharides (XOS)
Xylooligosaccharides are plant-based prebiotics that feed the good bacteria in the gut. They help probiotics work more effectively and promote long-term gut balance.
The Food Science and Nutrition journal published a study showing that xylooligosaccharides (XOS) can help relieve constipation. Participants who took XOS daily experienced better bowel movement and less discomfort. The study found that XOS supports the growth of healthy gut bacteria, improves stool consistency, and reduces constipation symptoms without causing gas or diarrhea [4].
