What is Vitamin B17?

Vitamin B17 is the popular name for amygdalin, a compound that occurs naturally in apricot kernels, bitter almonds, apple seeds and some legumes (notably lima beans). Bitter apricot kernels are the richest natural source — they contain substantially more amygdalin than the sweet variety and are the raw material used in purified supplement forms. It is not classified as an essential vitamin by mainstream medical bodies — "B17" is a market name. Because quality and labeling vary widely, knowing how to evaluate a product matters more than the name on the bottle.

01 What to check before you buy

Most shopping mistakes come down to one thing: not reading the active-ingredient line. A genuine product tells you exactly what is inside and how much. A weak one hides behind vague wording.

  • Active ingredient: the label should say amygdalin (or laetrile) with a milligram amount per tablet or capsule.
  • Source and purity: organic, non-GMO inputs are commonly preferred by buyers seeking natural products.
  • Dose clarity: a defined per-unit dose lets you measure intake precisely instead of guessing.
  • Manufacturing standard: GMP (Good Manufacturing Practice) and batch traceability signal consistent quality.
  • Reviews and provenance: testimonials and a verifiable seller history give real-world context.
Watch out: Some brands sell “B17” that is actually ground apricot kernels or fruit powder rather than pure amygdalin. An easy way to determine if the product is true amygdalin extract is to look at the color of the powder. If it is pure amygdalin the powder will be clear and white with a bitter aftertaste. If it is pulverized seeds the powder will be beige or brown which indicates it is not pure amygdalin.

02 Tablets vs. capsules vs. injectable

The three common forms suit different routines and dosing needs. Use this side-by-side to pick the one that fits how you actually take supplements.

Form Best for Notable trait Taste / handling
Tablets packs more active ingredient into a single piece Because they are made by compressing powder, tablets have same dose in a smaller size Mild natural taste
Capsules Sensitive palates Shell masks odor and flavor No medicinal taste
Injectable High-dose protocols Reaches the bloodstream directly Professional use only

03 How to verify authentic amygdalin

Authenticity is the single biggest variable in this category. Run any product you're considering through these five checks before paying.

The authenticity checklist

  • Ingredient name: "purified amygdalin" with a mg dose, not a vague blend.
  • Manufacturer: a named maker such as Novodalin with a verifiable supply chain.
  • Dose: a clear 100mg or 500mg per-unit figure.
  • Standards: GMP manufacturing and visible lot / batch numbers.
  • Seller: years of history, genuine reviews and reachable support.

04 Where to buy — and how to compare price

Vitamin B17 is sold through specialty supplement retailers and online health stores; general marketplaces and some natural-food shops carry it inconsistently. Prices vary widely, so compare on a cost-per-milligram basis rather than sticker price — a cheaper bottle with a lower dose can cost more per serving. Also weigh shipping, return policy and whether the seller can answer questions about sourcing.

Like any natural supplement it is important that you consult a healthcare professional before starting any regimen. Once you have done so, it is important that you are also aware of some potential side effects. These products are suggested to be taken with a meal as they can cause nausea or stomach discomfort when taken on an empty stomach. Additionally, people with low blood pressure may also experience some dizziness. If any of these side effects become present, discontinue supplement immediately and consult a physician. Some ways of preventing these side effects are to make sure to take supplement with a meal and to not exceed the suggested dose.

06 Frequently asked questions

A label that states purified amygdalin with a clear milligram dose, a named manufacturer such as Novodalin, GMP manufacturing, batch traceability, and a supplier with a verifiable history and genuine reviews. Avoid products listing only "apricot kernel powder" or "fruit blend."

Tablets pack the most active ingredient into a small size, capsules mask taste and odor, and injectable amygdalin is a high-dose form intended for use under professional guidance. The right choice depends on your preferred dose and routine.

Buy from an established supplier, check that the label specifies purified amygdalin and a milligram dose, confirm the manufacturer, and look for GMP standards and lot numbers. One specific pattern to watch for: some products declare "Vitamin B17" or "amygdalin" on the label but contain only ground apricot kernel powder or a fruit blend — not the purified compound. A label listing a milligram dose of purified amygdalin (not just "apricot kernel powder") is the key distinction.

Vitamin B17 (amygdalin) is not approved by the U.S. Food and Drug Administration. Legality varies by country, so check your local regulations and consult a healthcare provider before use.

Our amygdalin is extracted from raw, bitter apricot seeds using an established extraction method, for consistent purity and potency in every batch. Authentic material is white and crystalline; brown or off-color powder is a marker of imitation.

Yes. We offer free domestic shipping within the continental U.S. on orders over $90, and international shipping is available. Orders are processed and dispatched the next business day.

Whole apricot seeds do contain amygdalin naturally, but potency varies significantly by variety. Bitter kernels carry far more amygdalin than sweet ones — yet sweet kernels are what most grocery stores carry. Purified supplements provide a consistent, measured milligram dose and eliminate the batch-to-batch variability of whole seeds. If you are interested in whole seeds, consult a healthcare professional for personalized guidance.
