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 product: larch arabinogalactan, a soluble fiber derived from the larch tree. This ingredient is meant to support your digestive and immune health.

The product contains no inactive ingredients or fillers.

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: immune system and colon health support.
  • We looked for evidence on: Common cold, gut health, digestive function, immune function.
  • The closest evidence on file: Larch Arabinogalactan is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).

The evidence for larch arabinogalactan isn't established in the data we hold. For common cold and high cholesterol (hyperlipidemia), the rating is insufficient reliable evidence — meaning the current research doesn't yet support a clear claim about whether it works for these uses.

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 do experience bloating and flatulence, especially when first starting.

High-quality long-term safety data are limited, so caution and discussion with your doctor are advised before you use it regularly. There isn't enough safety data on file for pregnancy and breastfeeding — talk with your doctor or pharmacist about whether it's right for you in those situations.

Side effects, ingredient by ingredient Larch Arabinogalactan

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 — drugs given after transplants or for autoimmune conditions like azathioprine, cyclosporine, tacrolimus, or mycophenolate — talk with your doctor or pharmacist before you use this product. Larch arabinogalactan may theoretically interfere with how they work.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

ARA 6 is a fiber supplement that's generally well tolerated but has limited long-term safety data. The main concern is if you take medications to suppress your immune system — the product might interfere with them.

If that applies to you, or if you're pregnant, breastfeeding, or on any regular medications, check with your doctor or pharmacist before starting.

ARA 6 by D'Adamo Personalized Nutrition: Common Questions

Does ARA 6 by D'Adamo Personalized Nutrition interact with any medications?
Yes. Based on its ingredients, ARA 6 has a known interaction with 121 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
ARA 6 contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will this give me gas or bloating?
Some people do experience bloating and flatulence when they take larch arabinogalactan. Since it's a fiber, starting with a smaller amount and building up gradually may help your digestive system adjust.
Does larch arabinogalactan actually help with colds or cholesterol?
The evidence isn't clear yet. For both common colds and high cholesterol, we have insufficient reliable evidence to say whether it works. You'd want to talk with your doctor about whether this is the right choice for your health goals.
Is it safe to take while pregnant or breastfeeding?
We don't have enough safety data on file for pregnancy and breastfeeding. Talk with your doctor or pharmacist about whether it's appropriate for you in those situations — they can give you personalized guidance.
What's in this powder besides the active ingredient?
ARA 6 is just larch arabinogalactan — there are no fillers or other inactive ingredients.
