Ancestral Supplements vs Heart & Soil — Which Should You Buy?

Both brands score 9/10 on the Fitlab Scoring Protocol and dominate the premium beef organ supplement market. The decision comes down to one question: do you need Informed Sport drug-testing certification, or do you prioritise verifiable NZ sourcing with batch-specific COA data?

§ 02Nutrient Coverage

What each product actually provides

The organ composition determines your nutrient profile. Ancestral's liver-focus gives you very high retinol, B12, folate, and copper. Heart & Soil's 5-organ blend adds CoQ10 (heart), selenium (kidney), enzymes (pancreas), and tuftsin (spleen) at the cost of some depth in the liver nutrients.

§ 03Key Differentiator

The sourcing question

Ancestral Supplements

Ancestral Supplements

New Zealand, batch-verified

New Zealand is widely considered the highest regulatory standard for beef organ supplements. NZ has strict controls on pesticide use, antibiotic restriction, and pasture requirements. Ancestral publishes batch-specific COAs covering lead, cadmium, mercury, and arsenic — you can verify the exact lot you purchased. This level of traceability is rare in the supplement industry.

Heart & Soil

Heart & Soil

US regenerative, Informed Sport tested

Heart & Soil sources from named US regenerative farms, visible on their website. Regenerative agriculture goes beyond organic — it focuses on soil health, carbon sequestration, and animal welfare. Informed Sport certification adds a separate layer of quality assurance: every batch is independently tested against 200+ WADA-prohibited substances, which matters more than sourcing for competitive athletes.

Is the $120/year Heart & Soil premium worth it?For drug-tested athletes: yes, absolutely — Informed Sport batch testing is not optional in that context. For general users: Ancestral's NZ sourcing and batch COA provide strong quality assurance at a lower price. The premium only makes sense if you specifically need certification documentation.

§ 05Category Winners

Who wins each round

Sourcing Transparency
Ancestral Supplements
NZ sourcing with published batch-level COA is the gold standard. Ancestral discloses the exact lot you're consuming.
Third-Party Certification
Heart & Soil
Informed Sport certification tests every batch for 200+ WADA-banned substances. Essential for drug-tested athletes.
Organ Variety
Heart & Soil
5-organ blend vs liver-focused Ancestral lineup. More comprehensive micronutrient coverage across CoQ10, selenium, enzymes.
Price per Serving
Ancestral Supplements
$1.50 vs $1.83 — Ancestral is 18% cheaper per serving. Saves ~$120/year if you take it daily.
Label Transparency
Ancestral Supplements
Ancestral discloses exact organ weight per capsule. Heart & Soil uses a proprietary blend — individual organ doses unknown.
Retinol Safety
Heart & Soil
Liver-only formulas carry higher retinol risk. 5-organ dilution reduces this — safer for daily use and for those concerned about vitamin A toxicity.
Community Trust
Tie
Both brands are trusted in carnivore and ancestral health communities. Heart & Soil benefits from Dr. Saladino's audience; Ancestral from its longer track record.
FDA Compliance
Heart & Soil
Ancestral received an FDA warning letter in 2025 over marketing claims. Heart & Soil has a cleaner compliance record.

CONTEXT: THE 2025 FDA WARNING LETTER — ANCESTRAL SUPPLEMENTS

In 2025, Ancestral Supplements received an FDA warning letter. This is frequently misrepresented online:

—

The warning was about structure/function claims on their website — language implying the products treat or cure disease, which requires FDA drug approval.

—

It was NOT about contamination, safety failures, or product quality. No recall was issued.

—

The FDA issues hundreds of similar letters to supplement companies annually — it's a marketing compliance issue, not a product indictment.

—

Ancestral updated their website claims in response. Their COA transparency, sourcing, and formulations remain unchanged.

§ 07FAQ

Common questions

Are Ancestral Supplements and Heart & Soil the same quality?

Both are premium brands with verified NZ or US regenerative sourcing and published COA data. The key differences: Ancestral has better sourcing transparency (NZ + batch COA + disclosed organ doses); Heart & Soil has Informed Sport certification and a more comprehensive 5-organ blend. Neither is clearly 'better' overall — it depends on your priorities.

Which is better for drug-tested athletes?

Heart & Soil, without question. It's the only beef organ supplement with Informed Sport certification — every batch is tested against WADA's prohibited substance list. If you're in a tested sport, this isn't a preference issue: Ancestral Supplements has no batch-level drug testing whatsoever.

Which has better sourcing transparency?

Ancestral Supplements. Their New Zealand pasture-raised sourcing is the most documented in the category — they publish batch-specific COAs for heavy metals (lead, cadmium, mercury, arsenic) and you can look up the specific lot number on your bottle. Heart & Soil's US regenerative sourcing is credible and they name the farms, but NZ regulatory standards are generally considered the global benchmark for organ supplement sourcing.

Can I take both together?

Not recommended without medical supervision. Both are high in retinol (preformed vitamin A from liver). Stacking them could push you over the tolerable upper intake level of 10,000 IU/day for preformed vitamin A — particularly with Ancestral's liver-focused formula. If you want to combine products, choose one brand as your primary and consult a physician about your total retinol intake.

Which gives more CoQ10?

Heart & Soil wins significantly here. CoQ10 is concentrated in cardiac muscle — beef heart is the dietary source. Ancestral's liver-only formula contains negligible CoQ10. Heart & Soil's 5-organ blend includes beef heart, which is the reason organ supplements are often recommended for mitochondrial and cardiovascular support.

What's the FDA warning letter about for Ancestral Supplements?

In 2025, the FDA issued a warning letter regarding structure/function claims on Ancestral's website — specifically, language implying their products diagnose, treat, cure, or prevent disease (which requires FDA drug approval). This is a marketing compliance issue, not a product safety failure. The FDA issues similar letters to hundreds of supplement companies annually. Ancestral's COA data, sourcing transparency, and product quality are unaffected. They updated their website claims in response.

Which is better value for money?

Ancestral Supplements at $1.50/serving vs Heart & Soil at $1.83/serving. The $0.33/serving difference compounds to roughly $120/year. Whether that premium is worth it depends on what you're buying: for athletes who need Informed Sport certification, Heart & Soil's premium is justified. For general use, Ancestral's value is excellent given NZ sourcing quality and COA transparency.
