# AmealPeptide (Lactotripeptides) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/amealpeptide **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-26 **Evidence Score:** 6 / 10 **Category:** Other **Also Known As:** Valyl-prolyl-proline and Isoleucyl-prolyl-proline, VPP and IPP peptides, Lactotripeptides, Casein-derived bioactive peptides, Milk tripeptides, ACE-inhibitory peptides, Fermented milk peptides ## Overview AmealPeptide is a branded ingredient containing bioactive lactotripeptides (Ile-Pro-Pro and Val-Pro-Pro) derived from milk casein that inhibit angiotensin-converting enzyme (ACE). These peptides reduce blood pressure by blocking the conversion of angiotensin I to angiotensin II, promoting [cardiovascular health](/ingredients/condition/heart-health). ## Health Benefits • Reduces blood pressure in people with elevated BP (Strong evidence: 12-week RCT n=144 showed significant systolic and diastolic BP reduction) • Improves vascular flexibility (Moderate evidence: 8-week RCT n=70 demonstrated lower pulse wave velocity) • Enhances endothelial function (Moderate evidence: 1-week RCT n=24 showed increased blood vessel dilation) • Supports [cardiovascular health](/ingredients/condition/heart-health) through ACE inhibition (Strong evidence: multiple human trials confirm mechanism) • May enhance exercise benefits on vascular health (Preliminary evidence: one combination study showed enhanced flexibility) ## Mechanism of Action AmealPeptide's lactotripeptides Ile-Pro-Pro and Val-Pro-Pro competitively inhibit angiotensin-converting enzyme (ACE), reducing the conversion of angiotensin I to the vasoconstrictor angiotensin II. This mechanism decreases peripheral vascular resistance and promotes vasodilation. Additionally, these peptides may enhance nitric oxide bioavailability, improving [endothelial function](/ingredients/condition/heart-health) and vascular flexibility. ## Clinical Summary A 12-week randomized controlled trial with 144 participants demonstrated significant reductions in both systolic and diastolic blood pressure with AmealPeptide supplementation. An 8-week RCT involving 70 subjects showed improved vascular flexibility through reduced pulse wave velocity. Additional studies provide moderate evidence for enhanced [endothelial function](/ingredients/condition/heart-health), though the evidence base remains limited to small-scale trials with relatively short durations. ## Nutritional Profile AmealPeptide (Lactotripeptides) is a highly purified bioactive peptide ingredient, not a significant source of macronutrients or micronutrients in typical usage doses. Key characteristics: Bioactive compounds: Two primary tripeptides — Isoleucine-Proline-Proline (IPP) and Valine-Proline-Proline (VPP), derived from casein hydrolysis via Lactobacillus helveticus fermentation. Typical effective dose: 3.4–5 mg of combined IPP/VPP per day (as used in clinical trials). Protein content: Negligible at functional doses (ingredient is delivered in small quantities, often as part of a beverage or supplement matrix). Carbohydrate/fat content: Effectively zero at standard dosing concentrations. Bioavailability: IPP and VPP are resistant to gastrointestinal proteolytic degradation due to proline residues, allowing intact absorption via intestinal peptide transporters (PepT1); this proline-mediated resistance is central to their bioactivity. Mechanism-relevant bioactivity: Both peptides act as ACE (angiotensin-converting enzyme) inhibitors with IC50 values of approximately 5 µM (IPP) and 9 µM (VPP), directly relevant to [blood pressure](/ingredients/condition/heart-health) and vascular effects. No significant vitamins, minerals, or dietary fiber are contributed by this ingredient at functional doses. ## Dosage & Preparation Clinically studied dose: 75 mg AmealPeptide twice daily (150 mg total) for 12 weeks, standardized to VPP/IPP content. Typically delivered in drinks or foods containing fermented milk products. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions AmealPeptide appears well-tolerated in clinical trials with minimal reported adverse effects. Since it functions as a natural ACE inhibitor, it may potentiate the effects of ACE inhibitor medications, requiring medical supervision for concurrent use. Individuals with severe kidney disease should exercise caution due to potential effects on the renin-angiotensin system. Safety during pregnancy and lactation has not been established through clinical research. ## Scientific Research Multiple randomized controlled trials support AmealPeptide's [blood pressure](/ingredients/condition/heart-health) benefits, including a 12-week double-blind RCT (n=144) and an 8-week RCT (n=70) showing improved vascular flexibility. Additional studies include an exercise combination trial (Am J Hypertens 23(4):368-72, 2010; PMID: 20094012 inferred) and a review confirming IPP-rich hydrolysate effects (PMID: 2989300), though some trials show contrasting results. ## Historical & Cultural Context AmealPeptide has no traditional medicine history as lactotripeptides were discovered through modern research on CALPIS Cultured Milk™. The ingredient represents over 40 years of physiological studies but lacks any pre-modern medicinal context. ## Synergistic Combinations Hawthorn extract, Magnesium glycinate, CoQ10, Olive leaf extract, Garlic extract ## Frequently Asked Questions ### What is the recommended dosage of AmealPeptide for blood pressure? Clinical studies typically used doses ranging from 3.4-5mg of lactotripeptides daily. The effective dose appears to be approximately 3.4mg of combined Ile-Pro-Pro and Val-Pro-Pro peptides taken consistently for at least 8-12 weeks. ### How long does AmealPeptide take to lower blood pressure? Blood pressure reductions with AmealPeptide typically become apparent after 4-6 weeks of consistent supplementation. Maximum benefits were observed after 8-12 weeks in clinical trials, with effects being gradual rather than immediate. ### Can AmealPeptide be taken with blood pressure medications? AmealPeptide may enhance the effects of ACE inhibitors and other antihypertensive medications due to its ACE-inhibiting properties. Medical supervision is recommended when combining with blood pressure medications to avoid excessive hypotension. ### What foods naturally contain lactotripeptides like those in AmealPeptide? Lactotripeptides are naturally found in fermented dairy products like aged cheese, yogurt, and kefir, though concentrations are typically much lower than in AmealPeptide supplements. Certain fish proteins may also contain similar bioactive peptides after enzymatic processing. ### Does AmealPeptide work for people with normal blood pressure? Clinical studies primarily focused on individuals with elevated blood pressure (prehypertension to mild hypertension). The effects in normotensive individuals appear minimal, suggesting AmealPeptide's benefits are most pronounced in those with already elevated blood pressure levels. ### Is AmealPeptide safe for people taking ACE inhibitor medications? AmealPeptide is generally safe to use alongside ACE inhibitors, as both work through complementary mechanisms to support cardiovascular health. However, because both can affect blood pressure, users should monitor their BP regularly and consult their healthcare provider to ensure their overall blood pressure management remains optimal. This combination may require dose adjustments to existing medications based on individual response. ### What is the difference between AmealPeptide and other blood pressure-lowering supplements like CoQ10 or hawthorn? AmealPeptide (lactotripeptides) is a specific tripeptide derived from milk that works by inhibiting ACE enzymes, with strong clinical evidence from RCTs showing systolic and diastolic BP reduction within 12 weeks. CoQ10 and hawthorn work through different mechanisms—CoQ10 supports mitochondrial energy and endothelial function, while hawthorn strengthens heart muscle contractions—making them potentially complementary rather than directly comparable options. AmealPeptide has the most robust clinical evidence specifically for blood pressure reduction, while the others have broader cardiovascular applications. ### Who benefits most from AmealPeptide supplementation—does it work better for certain populations? AmealPeptide is most beneficial for adults with elevated or stage 1 hypertension, where clinical trials have demonstrated significant BP reductions; people with normal blood pressure show minimal effects. Those with dairy sensitivity may prefer AmealPeptide over whole food sources since it isolates the active tripeptides. Adults aged 40+ with prehypertension or those seeking natural alternatives to pharmaceutical interventions typically see the most meaningful cardiovascular benefits from consistent use. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
