HelloPharmacist Scorecard of Amino-Pro by DC

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Amino-Pro contains one active ingredient: lysine, an amino acid your body uses for protein synthesis and immune function. The product also includes inactive ingredients — calcium carbonate, vegetable cellulose, vegetable stearic acid, silica, vegetable magnesium stearate, and vanillin — which serve as binders, fillers, and flavor.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed

This product doesn't appear to be marketed for a specific use, so we graded Lysine's overall clinical evidence instead.

Moderate

Some clinical evidence supports Lysine for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Herpes labialis (cold sores) — rated "Possibly Effective" (Natural Medicines).

Lysine is possibly effective for cold sores (herpes labialis); research suggests it may help prevent or shorten outbreaks when taken as a supplement. For other uses listed — child growth, pressure ulcers, and diabetic foot ulcers — the evidence available to us is insufficient to rate whether it works.

If you're considering this for cold sores, talk with your doctor or pharmacist about what the research supports and whether it's right for you.

The evidence, ingredient by ingredient Lysine Casein Peptides

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Lysine is generally well tolerated at typical doses. At higher amounts, you may experience stomach upset, including abdominal pain, diarrhea, and indigestion.

Long-term safety hasn't been well studied. For pregnancy, the safety data on lysine supplements is not well established — check with your doctor before use.

There's also not enough reliable information on supplement use while breastfeeding, so caution is advised and you should talk with your healthcare provider.

Side effects, ingredient by ingredient Lysine Casein Peptides

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Lysine.
  • The most serious interaction on file is rated Minor.
  • For scale: 1 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take 5-HT4 agonist medications, check with your doctor or pharmacist before using this product — lysine may reduce how well these drugs work. No other interactions are documented for lysine in our data.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Only minor medication interactions are documented, and safety information is well characterized.

Amino-Pro is a single-ingredient lysine supplement that may help with cold sores. If you take 5-HT4 agonist medications, check with your doctor or pharmacist first.

Pregnancy and breastfeeding safety hasn't been well studied, so discuss it with your healthcare provider before taking it.

Antihypertensive Drugs

Theoretically, combining these casein peptides with antihypertensive drugs might increase the risk of hypotension.
Clinical research shows that some casein peptides, including the lactotripeptides isoleucine-proline-proline (IPP) and valine-proline-proline (VPP), can modestly reduce blood pressure in patients with hypertension.

5-Ht4 Agonists

Theoretically, lysine may reduce the effects of 5-HT4 agonists.
Animal research suggests that L-lysine is a partial serotonin receptor 4 (5-HT4) antagonist and inhibits diarrhea induced by the 5-HT4 agonist, 5-hydroxytryptophane.
