Bromelain
Bromelain (from Pineapple)
Protein-digesting enzyme from pineapple with systemic anti-inflammatory, digestive, and recovery benefits.
Bromelain is a mixture of proteolytic enzymes derived from pineapple stems. When taken with food, it aids protein digestion. When taken on an empty stomach, it's absorbed systemically and has anti-inflammatory, anti-edema, and recovery-enhancing effects. Used for sinusitis, surgical recovery, sports injuries, and arthritis.
Mechanisms of Action
Proteolytic Activity
Breaks down proteins and inflammatory debris
Anti-Inflammatory
Reduces inflammation through multiple pathways
Fibrinolytic
Helps break down fibrin deposits
Recommended Dose
500-2000mg (measured in GDU — aim for 2000-3000 GDU)
Optimal Timing
- On empty stomach for systemic effects
- With meals for digestive effects
Can be taken without food
Best Form
Capsules standardized to GDU (gelatin digesting units)
Alternatives: Tablets, Combined with other enzymes
GDU measures enzyme activity — more meaningful than mg. 2000-3000 GDU is a typical therapeutic dose.
Duration
Minimum: 1 weeks
Optimal: 2 weeks
Cycling: Not required
Note: For anti-inflammatory/recovery: take on empty stomach (30 min before or 2 hours after meals). For digestion: take with protein-rich meals.

Who Should NOT Take This
- Pineapple allergy
- Bleeding disorders
- Before surgery (stop 2 weeks prior)
Drug Interactions
May increase bleeding risk
May increase antibiotic absorption
Possible Side Effects
Tip: Take with small amount of food
Tip: Reduce dose
Tip: Discontinue if rash or swelling occurs
Warnings
- Stop 2 weeks before surgery due to blood-thinning effects
- May worsen bleeding disorders
- Empty stomach for systemic effects is important

“Since then, bromelain has gained recognition in both traditional and modern medicine for its potential therapeutic effects.”
Key Findings:
- It has a long history of traditional medicinal use in various cultures, particularly in Central and South America, where pineapple is native.
- This systematic review will delve into the history, structure, chemical properties, and medical indications of bromelain.
- Bromelain was first isolated and described in the late 19th century by researchers in Europe, who identified its proteolytic properties.
- Since then, bromelain has gained recognition in both traditional and modern medicine for its potential therapeutic effects.

“Therefore, the current literature does not support the use of natural agents as dental bleaching.© 2019 John Wiley & Sons, Ltd.”
Key Findings:
- The addition of non-peroxide agents into peroxide showed improvement in bleaching effect with the incorporation of these non-peroxide agents (p < .05).
- The evidence in literature suggested that natural bleaching agents incorporated to peroxide may improve the bleaching.
- Therefore, the current literature does not support the use of natural agents as dental bleaching.© 2019 John Wiley & Sons, Ltd.

“The results suggest that the bromelain appears to be effective in the control of pain, edema, and trismus after lower third molar surgeries; however, further high-quality studies are needed to confirm this finding.© 2018 John Wiley & Sons, Ltd.”
Key Findings:
- Following the selection process, seven studies were included in the systematic review and four in the meta-analysis.
- In terms of the risk of bias analysis, all the evaluated studies were classified as low or unclear risk of bias in the following criteria: selection bias, detection bias, and reporting bias.
- The results suggest that the bromelain appears to be effective in the control of pain, edema, and trismus after lower third molar surgeries; however, further high-quality studies are needed to confirm this finding.© 2018 John Wiley & Sons, Ltd.
Alves Nobre T et al. • Natural product research (2025)
“Bromelain reduced IL-1β, IL-6 and TNF-α secretion when immune cells were already stimulated in an overproduction condition by proinflammatory cytokines, generating a modulation in the inflammatory response through prostaglandins reduction and activation of a cascade reactions that trigger neutrophils and macrophages, in addition to accelerating the healing process.”
Key Findings:
- Among these compounds, bromelain is highlighted, as a cysteine protease isolated from the Ananas comosus (pineapple) stem.
- This review aimed to evaluate the anti-inflammatory activity of bromelain, as well as its pathways on inflammatory mediators, through a systematic review with in vitro studies on different cell lines.
- The search was performed in PubMed, Science Direct, Scopus, Cochrane Library and Web of Science databases.
Pereira IC et al. • Clinical nutrition ESPEN (2025)
“Our research suggests that bromelain possesses both prophylactic and curative qualities in terms of liver damage, as supported by its ability to decrease enzyme levels, enhance liver structure, reduce oxidative stress markers, and regulate lipid metabolism.”
Key Findings:
- Our research suggests that bromelain possesses both prophylactic and curative qualities in terms of liver damage, as supported by its ability to decrease enzyme levels, enhance liver structure, reduce oxidative stress markers, and regulate lipid metabolism.
- In summary, bromelain demonstrates a capacity to enhance liver function across a range of injury types.
- Further research warranted to confirm findings
