HelloPharmacist Scorecard of ARA 6 by D'Adamo Personalized Nutrition

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.

ARA 6 is a single-ingredient powder: larch arabinogalactan, a soluble fiber derived from larch trees. The product contains no inactive fillers or other ingredients—just the active fiber itself.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Larch Arabinogalactan's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: soluble fiber and immune support.
  • We looked for evidence on: Common cold, Immune function, Infection prevention, Gut health.
  • The closest evidence on file: Larch Arabinogalactan is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).

The evidence for larch arabinogalactan is not established in the data we hold. For common cold and high cholesterol (hyperlipidemia), the existing evidence is insufficient to make a reliable rating.

If you're considering it for one of those reasons, talk with your doctor about whether the current evidence supports its use for you.

The evidence, ingredient by ingredient Larch Arabinogalactan

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.

Larch arabinogalactan is generally well tolerated as a fiber. Some people experience bloating and flatulence, especially when first introducing it.

Long-term safety data are limited, so the data advises caution and provider guidance, particularly if you plan extended use or have underlying health conditions.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Larch Arabinogalactan.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 121 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 immunosuppressant medications—such as those used after transplant or for autoimmune disease—check your specific medications with the tool on this page before taking ARA 6. The ingredient may reduce how well these drugs work.
