A 2021 meta-analysis of nine randomised trials (Zhou et al., Nutrients 2021;13(9):2917, PMC8472736) reported oral astaxanthin improved skin moisture (SMD 0.53, p=0.03) and elasticity (SMD 0.77, p=0.009) versus placebo, but found no significant effect on wrinkle depth. This Ireland evidence guide covers astaxanthin's skin and eye research, dosage and whether 12mg is too much, EFSA safety (8mg/day from supplements assessed safe for adults, EFSA 2020, PMID 32874213), vegan options, and the two products we stock: NOW Foods Astaxanthin 4mg (vegan, EUR 22.95) and Healthy Origins Astaxanthin 12mg (EUR 58.50), dispatched from Dublin, normally within 24 hours.

Ashwagandha-containing food supplements are sold in Ireland under Irish and EU food law; they are food supplements, not licensed medicines, individual products must be notified to the FSAI (notification is not approval), and no EU-authorised health claim exists for ashwagandha (Food Safety Authority of Ireland; EU Regulation 1924/2006). This Ireland guide sets out the dated regulatory position (including Denmark's 2023 prohibition and the UK COT review unfinished as of April 2026), the safety signals regulators are assessing (liver, thyroid, blood glucose), what the clinical research has examined, dosage context, and Swanson Ashwagandha KSM-66 250 mg (60 veg caps, €17.45) with tracked delivery from Dublin.

The European Food Safety Authority (EFSA NDA Panel, EFSA Journal 2010;8(3):1462) set the adequate intake of dietary fibre for adults at 25 g per day, and a 2018 meta-analysis (Jovanovski et al., Am J Clin Nutr, PMID 30239559) found psyllium fibre significantly lowered LDL cholesterol across randomised trials. This Ireland guide compares inulin, psyllium husk, PHGG and resistant maltodextrin, the 25 g/day target, soluble vs insoluble fibre, authorised EU claims and how to start without discomfort, and covers Healthy Origins Sunfiber PHGG (225g, €25.95) with tracked delivery from Dublin under FSAI food-supplement rules.

The EFSA NDA Panel (EFSA Journal, 2015;13(7):4150) set an Adequate Intake of 4 µg/day of vitamin B12 for adults with no upper limit, and the NIH Office of Dietary Supplements puts absorption of a single 1,000 µg oral dose at about 1.3%, roughly 13 µg. This Ireland guide covers methylcobalamin 1,000 µg, methylcobalamin vs cyanocobalamin, food sources, who tends to run low, the 8 EU-authorised B12 health claims, and B12 vs B-complex, with NOW Methyl B-12 1,000 µg lozenges stocked by Probiotic.ie in Dublin

Pimentel et al. (Cedars-Sinai, Am J Gastroenterol, 2020, PMID 32023228) define small intestinal bacterial overgrowth (SIBO) as excessive bacteria in the small bowel causing bloating, gas and altered bowel habits, diagnosed by hydrogen/methane breath testing (Rezaie et al., 2017, PMID 28323273; hydrogen rise of 20 ppm by 90 minutes counts as positive). This Ireland evidence guide covers SIBO symptoms, breath-test access, the low-FODMAP diet, the contested role of fibre (Furnari et al., 2010, PMID 20937045), and where Healthy Origins Natural Healthy Fiber — a low-FODMAP Sunfiber PHGG powder, €25.95 — fits, with tracked delivery from Dublin under FSAI food supplement rules.

Bergsson et al. (Antimicrob Agents Chemother, 2001, PMID 11600381) showed caprylic acid, a medium-chain fatty acid from coconut oil, disrupts Candida albicans cell membranes in vitro, though no human trial confirms an oral supplement clears candida in people. This Ireland evidence guide covers caprylic acid, candidase enzymes, oregano oil, pau d'arco, garlic and daily probiotics for candida support, what the evidence does and does not show, FSAI regulatory status, and the Swanson Caprylic Acid 600mg (€16.95) and wider candida support range from Probiotic.ie.

A 2017 systematic review and meta-analysis by de la Iglesia-García et al. (NIHR Liverpool Pancreas Biomedical Research Unit, Gut, 2017, PMID 27941156) found pancreatic enzyme replacement therapy improved the coefficient of fat absorption versus placebo (83.2 vs 67.4, p=0.0001) in clinical exocrine pancreatic insufficiency, while Taylor et al. (Aliment Pharmacol Ther, 2010, PMID 19804466) concluded no single branded product was superior. This Ireland buyer's guide compares digestive enzyme supplements by enzyme type, use case and price, covering NOW Super Enzymes (180 caps, €42.95), Enzymedica Digest Basic (€23.95), BeanAssist (€16.95) and EatEnjoy Glutalytic (€15.45), all regulated as food supplements under FSAI guidelines with tracked delivery from Dublin.  

Irish Revenue confirmed on 29 September 2026 that a €2 Union Handling Fee per distinct item applies from 1 November 2026 to online orders shipped to Ireland from outside the EU, on top of the €3 customs duty per item in force since 1 July 2026 under Council Regulation (EU) 2026/382, and both apply to Amazon.co.uk and Amazon.ie items that are dispatched from Great Britain or any other non-EU location. This updated Ireland guide explains how to tell where an Amazon item ships from, how Amazon's Import Charges line works at checkout, what 'Amazon EU Sàrl' does and does not tell you, what third-party sellers mean for An Post fees, and where Irish supplement buyers can order from stock already in Dublin at Probiotic.ie with no import charges.

 Hu, Hu and Manson (Harvard T.H. Chan School of Public Health, J Am Heart Assoc, 2019, PMID 31567003) pooled 13 randomised controlled trials and 127,477 participants and found each additional 1 g/day of marine omega-3 was associated with a lower risk of myocardial infarction and coronary heart disease. This Ireland buyer's guide compares EPA and DHA doses across fish oil supplements, covers the EFSA-authorised heart and brain claims, dosage, vegan algae options and safety, and the omega-3 range at Probiotic.ie including Carlson Super Omega-3 1200mg (€42.50) and NOW DHA-500 (€32.95), shipped tracked from Dublin under FSAI food supplement guidelines.

This updated Ireland consumer guide covers how items are counted, VAT with and without IOSS, the separate An Post administration fee, orders over €150, Great Britain and Northern Ireland, refunds, and why goods already in stock in Ireland at Probiotic.ie in Dublin fall outside both charges.

iHerb has no Irish warehouse: its Ireland shipping page states that all orders are currently dispatched from the United States, so every iHerb order to Ireland is an import subject to the EU's €3 customs duty per item (Council Regulation (EU) 2026/382, since 1 July 2026) and, from 1 November 2026, the €2 Union Handling Fee per item confirmed by Irish Revenue on 29 September 2026. This updated Ireland guide explains what iHerb currently covers with its discretionary discount, what it has not confirmed about the November fee, how the per-item charges add up, how returns work, and where to buy NOW Foods, Swanson, Healthy Origins and Doctor's Best from stock already in Dublin at Probiotic.ie.
