Bromelain is an enzyme mixture from pineapple — famous for the typical "tingling tongue" when you eat fresh pineapple (the proteins in the tongue are slightly affected). Outside the kitchen, bromelain has its own place in supplement research around inflammatory processes, sports recovery and protein digestion. At Plenthera you will find bromelain in combination with quercetin (Doctor's Best Quercetin Bromelain) and as part of enzyme complexes (Neprinol AFD, Doctor's Best Digestive Enzymes).
Which bromelain suits you?
Overview of the common forms of bromelain on the market; at Plenthera you will find the combination with quercetin and the enzyme complexes.
| Form | GDU | Best for |
|---|---|---|
| 500 mg acid-resistant | 2,000 GDU/g | Standard, systemic absorption |
| High GDU 2,400+ | Premium | Highest activity, sports recovery |
| With quercetin (at Plenthera) | Variable | Classic combination, between meals |
| In an enzyme complex (at Plenthera) | Variable | Broad protein digestion or systemic complex |
What is bromelain?
Bromelain is a mixture of protein-digesting enzymes (proteases) from pineapple (Ananas comosus). It is mainly extracted from the stem (most potent) or the flesh (milder). Research topics: digestion, inflammatory processes, sports recovery, sinuses.
Bromelain was first used medically in 1957 and has since been one of the most researched plant enzymes. Unlike classic digestive enzymes that only work in the gut, bromelain taken between meals can also be absorbed systemically — part of it ends up in the blood.
The two main uses can be clearly distinguished. For digestion: taken with a meal, bromelain breaks down protein together with other proteases. For systemic absorption: taken between meals on an empty stomach, preferably in acid-resistant capsules so that it is absorbed in the gut without being broken down by stomach acid.
Also see our digestive enzymes category for broad enzyme complexes, and our turmeric category for a related line of research.
What does science say?
Clinical research into bromelain focuses on several themes: inflammatory processes (especially after surgery or injury), sports recovery, sinus complaints and digestion. These are mainly small-scale studies, often with doses of 200-2,000 mg/day. We describe these lines of research, without claims of effect.
If you use blood thinners (warfarin, NOACs): consult your doctor beforehand because of possible effects on blood clotting. With a pineapple allergy: avoid.
Bromelain at Plenthera and other forms on the market
Quercetin Bromelain (Doctor's Best) — at Plenthera
Bromelain combined with quercetin in vegetarian capsules (180 pieces) — the classic combination for taking between meals.
Bromelain in an enzyme complex — at Plenthera
Neprinol AFD (Arthur Andrew Medical) as a systemic enzyme complex with bromelain, serrapeptase and nattokinase; Doctor's Best Digestive Enzymes with 16 enzymes, including bromelain, for broad protein digestion with meals.
Other forms on the market
Single bromelain 500 mg (acid-resistant) — standard dose with approx. 2,000 GDU/g for systemic absorption between meals. Not currently stocked by us.
High-GDU bromelain (2,400+ GDU) — for those seeking the highest enzyme activity. Not currently stocked by us.
How do you use bromelain?
A simple basic approach for bromelain:
- Decide on your goal: digestion (with a meal) or systemic absorption (between meals, empty stomach).
- For systemic absorption: choose acid-resistant capsules — otherwise stomach acid breaks down the enzyme.
- Standard dose: 500 mg, 2-3 times a day.
- Around surgery or injury: only after medical consultation.
- If you use blood thinners (warfarin, NOACs): consult your doctor beforehand.
- With a pineapple allergy: avoid.
Myths and misconceptions about bromelain
Myth 1: "Eating fresh pineapple has the same effect as a bromelain supplement."
For digestion: partly yes. For systemic absorption: no — the amount is too low and bromelain is broken down by stomach acid. A supplement in acid-resistant capsules provides a standardised dose.
Myth 2: "Bromelain works immediately after intake."
For systemic absorption: 30-60 minutes. For digestion with a meal: immediately.
Myth 3: "The more bromelain, the better."
Doses above 3,000 mg/day show no additional effect and may increase the risk of bleeding in people using blood thinners.
Myth 4: "Bromelain is only for athletes."
Incorrect. Besides sports recovery, bromelain is also being researched for sinus complaints, swelling after surgery and digestion.
Combining bromelain with other supplements
Bromelain is often combined for the sports or joint theme. Popular combinations:
- Turmeric: a related line of research.
- Quercetin: a classic combination in supplements.
- Digestive enzyme complex: for broad protein digestion.
- Vitamin C: vitamin C contributes to normal collagen formation for the normal function of cartilage.
- Glucosamine + MSM: for the joint cluster.
- Magnesium: magnesium contributes to normal muscle function.
Frequently asked questions
What is bromelain?
A protein-digesting enzyme mixture from pineapple. Researched in relation to inflammatory processes, sports recovery and digestion.
What has been researched around bromelain and inflammation?
Mainly small-scale studies after surgery or injury, under medical supervision. That is a research context, not supplement advice.
When should you take bromelain?
Between meals for systemic absorption. With a meal for digestion.
How much bromelain per day?
200-2,000 mg depending on the goal.
Bromelain and sport?
Bromelain is being researched in relation to muscle soreness and recovery time after exercise.
What is GDU?
Gelatin Digestive Units — the unit for bromelain activity. Premium: 2,000-3,000 GDU/g.
Bromelain around surgery?
Only in consultation with the surgeon; bromelain can affect blood clotting.
Bromelain and blood thinners?
Possible interaction — consult your doctor beforehand.
Vegan bromelain?
Yes — from pineapple, plant-based. Check the capsule form (gelatine vs HPMC).
Bromelain and the sinuses?
Researched on a small scale; we make no statements about it.
