Based on the current evidence available through Pillser's research database, there is no direct data specifically examining the effects of Lactobacillus rhamnosus GG on triglyceride levels.

Here's what the evidence shows:

What Pillser's Database Contains

Pillser has research on Lactobacillus rhamnosus (the broader species) covering 10 health outcomes, but triglyceride reduction or lipid profile improvement is not among them¹. The areas with the most evidence for this species include:

• Reduced Inflammation – 15 studies (very low evidence, moderate effect)
• Reduced Oxidative Stress – 5 studies (low evidence, moderate effect)
• Improved Immune Function – 4 studies (low evidence, moderate effect)
• Improved Glycemia – 3 animal studies (low evidence, moderate effect)

Key Limitations

While some probiotic strains have been studied for lipid-lowering effects, the specific strain Lactobacillus rhamnosus GG has not been studied in relation to triglycerides in the available research¹. The evidence that does exist for Lactobacillus rhamnosus is largely based on:

• Animal and in vitro models
• Small study sizes
• Low-quality evidence overall

Bottom Line

At present, there is insufficient evidence to conclude that Lactobacillus rhamnosus GG helps lower triglyceride levels. If you're looking to manage triglyceride levels through supplementation, other ingredients (such as omega-3 fatty acids, niacin, or certain other probiotic strains) may have more robust evidence behind them.
