For healthcare professionals. This content is intended for practitioners only.
This article is a clinical reference for the THERA Nordic range. For each product it sets out what the product contains, what it is used for, how it is dosed and what to watch for. It then describes how the products are combined for common presentations, and closes with practical notes on timing and sequencing.
Throughout, the sequencing follows the logic of our 28-day plans: first calm and repair the mucosal lining, then support digestion with enzymes, then strengthen gastric acid, and finally feed the commensal flora with a gentle prebiotic.

Product reference
REZCUE (L-glutamine, zinc and L-carnosine)
The foundation product of the range. Each scoop supplies L-glutamine 2462 mg together with zinc 8 mg and L-carnosine 29.5 mg (supplied as zinc carnosine). Zinc carnosine is more effective for gut health when combined with L-glutamine, which is the rationale for the formulation.
Primary use: repair and protection of the gut lining, and soothing of gut inflammation. Appropriate for increased intestinal permeability ("leaky gut") and for acid reflux and heartburn, through soothing and protection of the mucosal lining along the whole GI tract. It can also be used regularly by anyone as part of a gut health routine, regardless of symptoms. It is the vegan-friendly option for gut lining repair.
Dose: one scoop (2.5 g) mixed into warm (not boiling) liquid, twice daily, morning and evening, with the evening dose best taken before bed. It works best on an empty stomach; if the patient feels discomfort it can be taken with a small amount of food.
Thyroid medication: leave at least one hour between thyroid medication and REZCUE; take REZCUE at least one hour after the medication, as they may inhibit each other's efficacy.
HEALIA (colostrum, collagen peptides, L-glycine and zinc carnosine)
Our most intensive gut support formula. Each 10 g scoop contains bovine collagen 4.5 g, bovine colostrum 4 g, L-glycine 1600 mg (2500 mg combined glycine content, as collagen is itself rich in glycine) and zinc carnosine 75 mg (16 mg zinc). The collagen and colostrum are sourced from grass-fed cows in Europe raised without antibiotics or hormones.
Primary use: repair and regeneration of the gut lining and soothing of inflammation in patients with a sensitive gut, increased intestinal permeability, or who are sensitive to L-glutamine (L-glutamine causes them symptoms), or where a more intensive gut lining repair strategy is wanted.
Choosing between HEALIA and REZCUE: HEALIA where the patient is sensitive to L-glutamine or needs more intensive repair; REZCUE for daily gut maintenance, mild to moderate digestive discomfort, or where L-glutamine is well tolerated. In more severe or advanced cases the two can be used together.
Dose: two scoops per day (20 g), one in the morning and one in the evening, stirred into a smoothie, juice, yogurt or a drink. Do not mix with anything hot.
Cautions: contains milk (bovine colostrum). Not suitable for vegans or vegetarians; use REZCUE instead. As with REZCUE, leave at least one hour between thyroid medication and HEALIA, taking HEALIA at least one hour after the medication.
Combined use with REZCUE: two scoops of HEALIA supply 150 mg zinc carnosine (32 mg zinc) per day, and REZCUE adds 16 mg zinc per day at standard dose. Together they provide 48 mg zinc a day.
Optimized Enzymes (broad-spectrum digestive enzymes)
A multi-enzyme formula to support digestion of the whole meal. Per capsule: acid-stable protease 100 SAPU, protease 90,000 HUT, amylase 25,000 DU, alpha-galactosidase 800 GALU, cellulase 1,500 CU, a gluten- and casein-targeting enzyme (DPP-IV) 1050 DPPU, glucoamylase 55 AGU, invertase 400 SU, lactase 1,000 ALU, lipase 3,500 FIP, phytase 45 FTU and xylanase 725 XU.
Primary use: bloating, gas and other symptoms of indigestion. The formula includes an enzyme that targets the proteins associated with sensitivity to the gluten in wheat, which also digests milk proteins. Where symptoms stem from low stomach acid, Triple HCL may be the more effective choice; in many patients the combination of the two works best.
Dose: one capsule three times daily with a meal. Two capsules may also be taken on an empty stomach before bed for additional benefit.
Caution: do not use in patients with an active gastric (stomach) ulcer.
Triple HCL (betaine hydrochloride, gentian and protease)
Supports digestion in three ways. Betaine hydrochloride increases the amount of hydrochloric acid in the stomach, which is needed for protein digestion, for the gastric defence against ingested bacteria, and for the absorption of minerals and vitamins. Yellow gentian root (natural bitters) stimulates the body's own secretion of hydrochloric acid and bile acids. Promod® protease, an acid-stable protease of fungal and papaya origin, supports digestion of dietary protein. Per capsule: betaine hydrochloride 550 mg, yellow gentian root extract 50 mg, Promod® protease (fungal and papaya-derived, acid-stable) 600 APU. The capsule is vegan.
Primary use: heartburn, acid reflux, indigestion, bloating, post-meal fatigue and general digestive discomfort associated with insufficient stomach acid. Stress and ageing in particular can reduce gastric acid, and hypochlorhydria can significantly impair digestion and nutrient absorption. Triple HCL is often more effective alongside REZCUE and Optimized Enzymes.
Dose (titration):
- Start with 1 capsule with each meal.
- If symptoms do not change after 2 days, increase to 2 capsules per meal.
- Repeat as needed, working up to a maximum of 4 capsules per meal.
- Stay at the dose that feels best; there is no need to take more.
- If the patient feels any discomfort, irritation or other side effects, reduce the dose.
Take only with meals, never on an empty stomach. In our 28-day plans the simplified rule is 1 capsule with a smaller meal and 2 capsules with a meal higher in protein and/or fat.
Patients new to betaine HCl: we recommend two weeks of REZCUE first.
Caution: not for use in patients with an active gastric or duodenal ulcer. Where an ulcer is suspected, investigate and treat before introducing Triple HCL.
Bacti-Balance (garlic extract and oregano oil)
An antimicrobial formula combining a high-potency garlic extract (allicin 5000 mcg per capsule) with oregano oil (carvacrol 36 mg per capsule). It is not a probiotic. The capsule is enteric-coated (delayed release) so that the actives are delivered to the small intestine.
Use: taken as a course. The product text describes it as cleansing the intestine and balancing the gut microbiome, and research interest in garlic and oregano oil centres on their antimicrobial properties.
Dose: like pharmaceutical antibiotics it is best taken as a course. One capsule three times daily with a meal, for a course of 40 to 60 days (2 to 3 bottles).
Daily Healthy Fibre (soluble prebiotic fibre)
A blend of three soluble fibres: acacia fibre and baobab fruit powder (5000 mg per scoop) and partially hydrolysed guar gum (3000 mg per scoop), 8000 mg in total. It is a prebiotic fibre that feeds the commensal bacteria and so supports the composition of the gut microbiome. Listed as IBS and FODMAP friendly.
Primary use: a prebiotic for any patient, regardless of symptoms; it is particularly useful in IBS, irregular bowel movements, and for patients who want a high-quality fibre to feel full for longer. The product text also notes that fibre can help regulate blood sugar levels and support weight management.
Dose: mix one scoop into a smoothie, juice, yogurt, porridge, a drink or food. Up to 3 scoops per day. In our IBS and heartburn plans it is introduced at 1 to 2 scoops per day.
Move (magnesium citrate and oxide)
An osmotic magnesium laxative for constipation. Each 1.7 g scoop supplies 580 mg of magnesium as citrate and oxide. It is dosed to stay in the gut rather than be absorbed, so it acts by hydrating the stool so it passes more easily and comfortably, without stimulating the bowel. It is osmotic rather than stimulant, so it does not lose effect over time, and it is non habit-forming. Two forms of magnesium are used so that it works whatever the stomach acid is doing.
Primary use: occasional constipation, and the first step of the chronic constipation plan. It is not a magnesium supplement for systemic repletion, sleep or other indications.
Dose: 1 to 3 scoops in at least 250 ml of water before bed. Start with one scoop and increase the nightly dose until the desired bowel movement is achieved. The patient sets the dose.
Combination protocols by presenting condition
Each protocol below names the products in the order in which we introduce them. The 28-day plans are the fixed protocols we publish; the other presentations are built from the same products and the same sequencing logic.
Heartburn, acid reflux and indigestion
Published as the Heartburn and Indigestion 28-day plan. There is always a degree of inflammation associated with heartburn, so the first step is calming the stomach and gut lining. Incomplete and slow digestion is one cause of acid reflux, so enzymes and a gentle prebiotic follow, and only then is gastric acid strengthened.
- Week 1, calming: REZCUE, 1 scoop twice daily.
- Week 2, supporting: continue REZCUE. Add Optimized Enzymes, 1 capsule three times daily with a meal, and Daily Healthy Fibre, 1 to 2 scoops per day.
- Week 3, strengthening: continue the above and add Triple HCL: 1 capsule with a smaller meal, 2 with a meal higher in protein and/or fat.
- Week 4, consolidating: maintain the routine. The patient can try dropping Triple HCL with lighter meals, and can try taking 2 Optimized Enzymes capsules on an empty stomach before bed.
Exclude active gastric or duodenal ulceration before week 2 (Optimized Enzymes, introduced in week 2, and Triple HCL, introduced in week 3, are both contraindicated).
Patients on a proton pump inhibitor: introduce REZCUE alongside the current PPI. Once the patient is established on REZCUE, halve the PPI dose first, then wean off slowly under the prescriber's supervision, in line with the patient's symptoms. If symptoms recur, hold at the low dose and continue REZCUE for a further 4 weeks before attempting the wean again. Any change to acid-suppressing medication remains the prescriber's decision.
IBS and bloating
Published as the IBS and Bloating 28-day plan. IBS is treated as an imbalance of the gut: the plan combines supplement support with a FODMAP diet, started from day 1.
- Week 1, calming: REZCUE, 1 scoop twice daily, plus the FODMAP diet.
- Week 2, supporting: continue REZCUE; add Optimized Enzymes, 1 capsule three times daily with a meal.
- Week 3, strengthening: continue the above; add Triple HCL, 1 capsule with a smaller meal and 2 with a meal higher in protein and/or fat.
- Week 4, consolidating: continue all; add Daily Healthy Fibre, 1 to 2 scoops per day.
By stool pattern. The published plan is not split by IBS subtype. For constipation-predominant IBS, add Move at bedtime (1 to 3 scoops, titrated) or follow the chronic constipation plan below. For diarrhoea-predominant IBS, follow the IBS plan as published and do not add Move.
Increased intestinal permeability ("leaky gut")
The product texts use "leaky gut" colloquially for increased intestinal permeability. Our approach is repair of the lining first, then a prebiotic.
- Standard: REZCUE, 1 scoop twice daily. After the lining has been supported for a few weeks, add Daily Healthy Fibre, starting at 1 scoop per day, as the prebiotic.
- Glutamine-sensitive patients, or where more intensive repair is wanted: HEALIA, 2 scoops per day, in place of REZCUE.
- More severe or advanced cases: REZCUE and HEALIA together (see the zinc note under HEALIA).
- Digestive support where there are also symptoms of indigestion: add Optimized Enzymes and, if the patient has had two weeks of REZCUE, Triple HCL, as in the heartburn and IBS plans.
Post-antibiotic gut restoration
REZCUE at the standard dose, as a 4-week course, for the mucosal effects of an antibiotic course. Daily Healthy Fibre can be added as a prebiotic once the patient is established on REZCUE.
Chronic constipation
Published as the Chronic Constipation 28-day plan. For occasional constipation, Move alone is the first step.
- Week 1, relief: Move, 1 to 3 scoops in at least 250 ml of water before bed, titrated up from 1 scoop. Encourage an extra litre of water each day.
- Week 2, balancing: add Daily Healthy Fibre, one scoop at a time, up to 3 scoops per day. Continue Move only if the patient is still constipated. Continue the extra water.
- Week 3, strengthening: continue the fibre and water; add Triple HCL with meals, 1 capsule with a smaller meal and 2 with a meal higher in protein and/or fat. Always with a meal; reduce the dose if there is any discomfort.
- Week 4, consolidating: maintain the routine. The patient can try dropping Triple HCL with lighter meals.
Inflammatory bowel disease, as adjunct
REZCUE (1 scoop twice daily) can be used as a gut lining and anti-inflammatory support alongside the patient's own treatment. Where glutamine is not tolerated, or a more intensive approach is wanted, HEALIA can be used instead, or both together in more severe cases. Daily Healthy Fibre may be introduced gradually.
Practical notes
Order of introduction
The logic of our plans is: calm the lining (REZCUE, or HEALIA); support digestion (Optimized Enzymes); strengthen gastric acid (Triple HCL); feed the commensal bacteria (Daily Healthy Fibre). In constipation, Move comes first for relief. For patients who have not used betaine HCl before, give two weeks of REZCUE before Triple HCL.
Timing
| Product | When to take |
|---|---|
| REZCUE | Morning and evening (last dose before bed); best on an empty stomach, with a little food if it causes discomfort. Mix with warm, not boiling, liquid. |
| HEALIA | One scoop morning, one evening, in a smoothie, juice, yogurt or drink. Not with anything hot. |
| Optimized Enzymes | With a meal, three times daily. Optionally 2 capsules on an empty stomach before bed. |
| Triple HCL | Only with meals, never on an empty stomach. |
| Bacti-Balance | With a meal, three times daily, as a 40 to 60 day course. |
| Daily Healthy Fibre | At any time, mixed into food or a drink. |
| Move | Before bed, in at least 250 ml of water. |
Thyroid medication
Leave at least one hour between thyroid medication and REZCUE or HEALIA, taking the supplement at least one hour after the medication. The product texts state that they may inhibit each other's efficacy.
Vegan and vegetarian patients
REZCUE and Triple HCL are vegan. HEALIA is not (milk, bovine collagen and colostrum).
