If you are shopping for a B17 vitamin, you are really shopping for bitter apricot kernels — whole seeds or powder that carry amygdalin, the compound people call vitamin B17. The single most useful thing to know up front: bitterness is the signal. A kernel that actually tastes sharply bitter almost certainly carries more of the compound than one that tastes like a sweet almond, so the flavor you are trying to avoid is the flavor that tells you the product is real.
I’m Min — the founder and writer behind Gadgets Feed. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Every pick below is a genuine amygdalin product, and the differences come down to origin, dosage guidance, and how bitter the kernel actually is. This breakdown of the b17 vitamin market covers nine real options so you can match one to your own routine.
Our Picks at a Glance
How To Choose The Best B17 Vitamin
Buying apricot kernels is not like buying a bottle of capsules. The kernel is a whole food, so origin, age, and bitterness all change what you actually get. Here are the four things that decide whether a bag earns a spot in your kitchen.
Taste is your only at-home test for amygdalin
Bitter apricot kernels carry amygdalin — the compound marketed as vitamin B17 — and the bitterness tracks how much is inside. A kernel that tastes like a sweet almond is close to useless to a B17 shopper. A kernel that makes you wince is doing its job, and that reaction is the one honest check you can run without a lab.
Read the daily-limit line before you buy
Several of these brands print an explicit cap on the package — 3 kernels a day is the most common figure you will see. That single number tells you how long a one-pound bag actually lasts. If you are eating a few kernels daily, a bigger bag is a real value; if you are experimenting, a smaller one keeps you from storing kernels past their best.
Origin and packing date move faster than you think
Apricot kernels lose their punch as they sit. Kernels held for months in a warehouse taste flatter and less bitter than a current-year crop. California-grown and Pakistani-sourced bags both appear in this list, and the brands that talk about current-crop packing or daily packaging are usually the fresher ones.
Kernel size decides your dose count
Two bags can both say one pound and hold very different numbers of kernels. Larger kernels mean fewer pieces for the same weight; smaller kernels mean you count out more of them to hit the same amount. If you already know your daily number, size matters more than the total on the bag.

In‑Depth Reviews
1. Apricot Seeds California Grown Bitter Raw 100% All Natural From Organic Farms 1 LB
Our pick — over 4.5★ from 900+ verified ratings; the strongest balance of quality and price.
A one-pound bag of current-year California kernels where the bitterness does the talking for the label.
This bag does one thing better than almost anything else here: it tells you exactly what year you are eating. The kernels come only from the current crop, packaged daily, with the maker promising freshness for at least a year from the packaging date. Most imported kernels sit in a warehouse waiting for bulk buyers — this one skips that wait, and buyers consistently describe the kernels as fresh and high quality.
What wins people over is quality more than anything else — the review pages single it out far more than any other trait, with freshness and perceived value close behind. Buyers report a real dosage ramp rather than a jump: as owners put it, one customer “Started 1 seed/day w/ meals, gradually increased to 15/day over weeks.” Others mention milder side effects like a laxative effect early on and recommend easing in for that reason.
The catch is bitterness, and the brand is upfront about it. It sells only truly bitter kernels and argues the sharper the taste, the more active compound you are getting — and reviewers split on whether that is a feature or a hurdle. Some describe them as less bitter than competing brands with a nice crunch; others find them noticeably strong. This is the bag to pick if you treat kernels as a measured daily food and want the origin and crop tracked.
What the bag delivers
- Current-year California crop, packaged daily, so kernels arrive fresh rather than warehouse-aged
- Vegan, gluten-free, pesticide-free and GMO-free kernels from farms the seller names directly
- Label discloses amygdalin content, which owners mention most competing brands skip
Where it asks patience
- The bitterness is deliberate and strong — several buyers suggest starting with one kernel and building slowly
- Mild digestive effects show up if you jump into a full daily serving too fast
Made for: anyone who wants a traceable US-grown kernel and is willing to ramp up gradually.
Rethink it if: you want a snackable kernel — its whole point is the sharp, bitter bite.
2. Nutri Nibblers Certified Organic Bitter Apricot Seeds 1Lb Freshly Packed Bitter Apricot Kernels Organic Raw In Eco-Friendly Resealable Bag Vegan,Non-GMO,Gluten Free – Rich In Vitamin B17 (Amygdalin)
Certified organic kernels at the friendliest price here — if your taste buds can handle the honesty.
Here is where you feel the packaging difference immediately: this pouch is the most compact of the whole group, measuring 8.46 x 6.22 x 2.09 inches against the California bag’s 8.98 x 5.91 x 2.99 inch footprint, so it tucks into a tighter cupboard shelf. It holds the same full pound, certified organic, non-GMO, and processed in a cGMP-certified facility — the manufacturing standard that focuses on cleanliness and consistency.
The kernels themselves come from Pakistan and arrive in an eco-friendly resealable pouch, with the maker asking you to store them cool, between 0 and 10 °C. Quality is the clear strong suit here, outranking every other trait buyers bring up, with value for money next in line. Customers note no stale or broken seeds in the bag, and the resealable pouch draws its own praise.
Bitterness is the honest divider. Some buyers find these perfectly bitter; others say the taste reminds them of almonds — milder than the sharpest brands. One owner who pushed to three to five kernels a day reported swollen, painful glands under the arms and around the chest and scaled back. That is one person’s experience, not a rule, but the package label itself caps you at three kernels per day, and this is a bag to respect that limit with.
Price-to-label read: it is the lowest-cost certified organic whole-kernel option in this lineup and still carries the organic, non-GMO and cGMP processing claims, so nothing about the value position feels like a shortcut.
The almonds problem: if you are buying specifically for the amygdalin signature, a sweeter kernel is a weaker signal — buyers who want a punishing bite should look at the California and Buy Apricot Seeds bags instead.
Reach for this if: certified organic status and a lean price tag matter more to you than maximum bitterness.
Pass it over if: you want the strongest taste signal as your proof of potency.
3. Raw Organic Bitter Apricot Kernel Powder, The Best Natural Source of Vitamin B17 | Very Rich in Fatty Acids, Vitamins and Minerals | Used as a Cleansing Face Balm – 7 Oz.
Skip the cracking entirely — this is the only ground option in the lineup, and it splits its life between the kitchen and the bathroom shelf.
If you have ever tried to shell an apricot pit, you know the awkward part. This is the kernel already ground into a fine powder, and the maker notes the seeds are milled without contact with metal so the flour keeps what the seed carried. It ships at 7 oz rather than a full pound, which matters because you are measuring scoops rather than counting kernels.
Its second identity is skincare. The powder is positioned as a natural exfoliant, and the maker calls it the star ingredient in its own cleansing face balm. The skin-type claim stays broad — the brand markets it as suitable for all skin types and built around fatty acids and minerals rather than a targeted fix. Reviewers who bought it for soap-making report it works nicely in cold process batches, and others mix it straight into salads for their own reasons.
Quality is the trait buyers point to most by a wide margin, and the bitterness holds up: owners describe the powder itself as distinctly bitter, which is exactly what a B17 shopper is testing for. It has been sold since December 2015, so this is a long-running formula rather than a newcomer. Expect a powder texture rather than a crunch, and plan your storage accordingly.
Two-shelf pick: it is the only product in this group that reads as a genuine kitchen-and-skincare crossover, and the exfoliation angle is called out directly by soap makers using it in real batches.
Powder caution: a 7 oz pouch is a fraction of the weight of the one-pound bags, so if you are measuring daily scoops for oral use, budget your refills before you commit.
Best match: people who want amygdalin in scoop form, or who make their own soap and body products.
Not the one for: anyone who enjoys the ritual of cracking a kernel and chewing it whole.
4. Cure Wid Pure Certified Organic Apricot Seeds 1lb – Bitter Apricot Kernels
The organic Pakistani bag that leans hardest into freshness claims and expects you to refrigerate it.
Certified organic, non-GMO, and raw — this bag checks the purity boxes and then adds one instruction most competitors leave off. The maker asks you to store it between 0 and 10 °C, meaning it belongs in the fridge or a cool pantry if you want it to hold up. Kernels are grown in Pakistan’s apricot orchards, processed in a cGMP-certified facility, and sealed in an eco-friendly resealable pouch.
Quality again leads what buyers talk about, with value for money and health benefits following. The review pages frame it as a solid source of vitamin B17 with a nice taste for some and a bitter aftertaste for others — a genuine split rather than a verdict. It also carries an explicit three-kernels-a-day ceiling, and buyers treat that number seriously; one described it as not a snack food and nothing like a mild nibble.
Where this one earns its spot is the middle ground it occupies: cheaper than the premium California bags, organic like the Nutri Nibblers, but with the supermarket-style resealable design and a storage instruction that tells you the maker takes shelf life seriously. The powder option above is the more flexible format; this is the straightforward whole-kernel bag.
Buyers keep coming back for
- Certified organic, non-GMO and raw kernels in a resealable eco-friendly pouch
- Explicit 0–10 °C storage guidance that helps you keep kernels fresh longer
- Clear three-kernel-a-day ceiling printed on the package
Worth knowing before you order
- The strong bitterness catches first-timers off guard — plan to mix it into a shake
- Kernel size runs small, so a daily count adds up faster than with large-kernel brands
Choose it for: an organic whole kernel with a resealable pouch and fridge-friendly storage advice.
Choose the California bag instead if: you want bigger kernels and a US origin story with daily packing.
5. Drybox Bitter Apricot Kernels Raw Natural Organic NonGMO Vegan Source of Vitamin B17 and B15, Resealable Bag 16 oz/ 1 lb Bag, 1 Pack
A certified list of “free-from” claims attached to the least bitter kernel in the lineup.
This is the one to consider if you want kernels without the face-pulling. Owners describe them as not really bitter at all, one going so far as to say even their children would eat them for the health benefit. That is unusual in a category where bitterness is treated as a badge of potency, so go in understanding the trade-off: a gentler taste usually signals less of the compound that makes the sharp brands famous.
Drybox positions the bag on pure ingredients rather than punch. Single-ingredient snack, no preservatives, no sugar, no dyes, no fillers — organic, raw, vegan, non-GMO, gluten-free and Kosher Pareve. The kernels absorb their flavor from the Mediterranean region where they grow, and the maker points to amygdalin and B15 content as the reason to eat them. Texture is almond-like, which is exactly why buyers chop them into vegetables, soups and salads to blunt the taste further.
What people enjoy most here is simply the eating — taste leads the conversation by a clear margin over quality. One buyer’s only wish was larger kernels, which is the recurring small note. Compared with the Buy Apricot Seeds bag’s larger California kernels, this one runs smaller, so a taste-first snacker will finish the bag faster.
The clean-label case: zero preservatives, dyes, fillers or added sugar, made in a zero-waste facility on renewable energy and partnered with the TEMA Foundation for reforestation work — the sourcing story here is as strong as the ingredient list.
Honest trade-off: mild flavor is pleasant, but if your whole reason for buying is amygdalin density, the sharper-tasting bags above give you the stronger signal.
Pick it when: taste tolerance is your main obstacle and you want kernels you can genuinely snack on.
Look upward if: you measure a bag by how bitter it tastes, not how easy it is to eat.
6. Bitter Apricot Seeds/Kernels, Natural Source of Vitamin B17, Large and Raw, Vegan, Non GMO California Grown, In a Recyclable Stay Fresh Resealable Pouch 1lb
Two words define this bag: large and bitter, backed by over a decade of California supply.
Size is the reason to start here. These are explicitly sold as large, California-grown kernels, and the maker has been supplying them for more than ten years from the same state. The bag itself is a fully recyclable rice paper pouch — a genuinely different packaging choice than the plastic resealable bags everywhere else in this list, and one that keeps the “stay fresh” seal.
Taste is the loudest topic overall, and it splits hard — some call them delicious, others call them bitter, and a few admit it is a lot even for a committed buyer. One note worth flagging for budget watchers: the wish for a lower price shows up. That is the honest frame — you are paying a premium for large, US-grown kernels with a recyclable pouch.
Why people choose this bag
- Large California-grown kernels with over ten years of continuous supply behind them
- Fully recyclable rice paper stay-fresh pouch — a real packaging differentiator
- Buyers describe them as fresh and as a rich natural source of B17 and laetrile
Honest limits
- The bitterness is the main talking point and the reviews are genuinely split on it
- Price comes up as a wish in some reviews even from satisfied buyers
Best suited to: long-time users who want large kernels and appreciate a recyclable pouch.
Skip if: bag weight and maximum bitterness per bite are your two highest priorities.
7. Mighty Apricot USDA Organic Bitter Apricot Seeds 16 Oz (1LB), Vitamin B17
USDA-certified organic kernels from Turkey with far and away the deepest review history in this lineup.
If you want a purchase decision backed by the widest set of buyer experiences available in this category, this is the bag — it holds the largest body of owner feedback of any product here, at nearly four thousand ratings. The kernels are USDA certified organic, non-GMO, vegan and gluten-free, produced in a GMP-compliant facility as a product of Turkey, and packed in a resealable 16 oz bag.
What buyers respond to most is quality, which dominates the conversation by a wide margin, followed by the health benefits people attribute to daily use and their overall freshness. The kernels are described as generous in size, and the flavor lands as pleasantly surprising for some buyers and not remotely snack-like for others. The bite is sharp and comes with a numbing sensation — the brand is direct that bitterness is the nature of the seed, not a defect.
The package prints an explicit ceiling of up to three kernels per day and asks you to read the warning on the back. Buyers take that seriously: one described them as peanut-sized with a brief but sharp bite and ate three a day without issue, another warned against eating handfuls and said a couple a day suffices. Keep the resealable bag shut and cool, and you get the least-guesswork bag in the group simply because so many people have eaten from it before you.
Deepest signal available: With roughly 3,800 owner ratings behind it, this is the one product here where you read patterns rather than isolated opinions.
Read the package: the three-kernel daily limit and back-of-pack warning are the maker’s own instructions and are part of what you are buying.
Confident pick for: first-time buyers who want the widest owner track record before committing to a daily habit.
Consider the California bags instead if: you prefer US-grown origin over the broadest review base.
8. Nutriseeds Bitter Apricot Seeds | California Grown | Certified Pesticide and Herbicide Free | 2LB (32oz) roughly 1,500 Kernels | Best Source of Natural B Vitamins
A whole kilogram-class bag of lab-tested, pesticide-free California kernels that lasts daily users for months.
The headline number here is on the bag itself: a 32-ounce, two-pound resealable bag holding roughly 1,500 kernels, with the maker noting a pound lasts for months depending on use. Each seed is lab tested and stated to contain roughly 20 mg of B17, and the kernels are air dried, never heated or cooled, to preserve nutrition. They come from a certified organic facility in California, free of pesticides and herbicides, non-GMO, gluten-free, vegan, Kosher and Paleo friendly.
Bitterness is treated as a feature, not a bug: the brand says the bitterness in the seed indicates how much B17 is inside, and recommends grinding the kernels into smoothies, shakes, oatmeal, soups and salads to work them into your day. Buyers agree the taste is genuinely there — reviewers describe them as fresh and distinctly bitter, with one noting they are easier to eat after soaking, and the bigger bag repeatedly called a great deal.
The one caveat is size. These kernels run about half the size of some competing California brands, so for the same amygdalin intake you may need to take more of them — roughly two Nutriseeds to one of a larger brand by weight. A few kernels also arrive not fully shelled, and those hard shells are worth handling carefully before you chew. The upside is the sheer volume: compared with the one-pound bags above, this one twice-over keeps daily users stocked far longer.
Where the value lands
- 32 oz bag with roughly 1,500 kernels, sized for months of daily use
- Lab tested for B17 levels, with roughly 20 mg per seed stated by the maker
- Air dried, never heated or cooled, from a certified organic California facility
The trade-offs
- Kernels run about half the size of some competing California brands, so more pieces per dose
- A few kernels arrive with shell fragments that need picking through before eating
Built for: daily users who want one bag to carry them through months of use.
Think twice if: you prefer large kernels you can count out in small numbers.
9. Apricot Kernels (Seeds) 2lb / 32oz Bag (Resealable) Raw and Bitter
The large, potent California kernel that comes as two sealed one-pound pouches instead of one open bag.
This is the same California-grown supply line behind the large-kernel bag above, sold here in a two-pack of re-sealable “stay fresh” zip-lock pouches totaling two pounds. The format is the quiet advantage: you open one pound and leave the other sealed, so the second half stays fresher than it would in a single large bag you dip into daily.
Quality is what buyers lead with, and by a wide margin — it outranks value, effectiveness and freshness in the conversations around this product. Owners describe the seeds as large and uniform with a bitter, lingering amaretto flavor, plus a crisp texture they read as a freshness signal. Effectiveness earns its own mentions here more than in most of the lineup, which tells you people are buying this for a reason beyond snacking.
Potency is the flip side. These kernels carry roughly twice the amygdalin of average seeds, so long-term buyers who once ate thirty or more a day now take about five at a time. At higher doses, some reviewers point out mouth numbness and headaches, and one caps their own intake at nine kernels at a time. The bag prints no candy-loose advice — treat this as a measured daily food, not a handful from the pouch.
Format you will notice: two separate one-pound sealed pouches solve the “big bag goes stale” problem that plagues every 32-ounce product in this category.
Potency needs respect: the same larger kernels that make it efficient also make it easy to overdo — the buyers who stick with it keep their daily count modest.
Right for you if: you take kernels daily and want a second sealed pound waiting in reserve.
Better off elsewhere if: you would rather buy one smaller bag and keep your storage space clear.
Understanding the Specs
Bitterness as a potency signal
Bitter apricot kernels carry amygdalin — the compound sold as vitamin B17 — and the sharpness of the taste tracks how much is inside. That is why every honest product in this category is proudly bitter and warns you about it. A kernel that tastes like a sweet almond is a weaker kernel, which is why the milder bags here trade flavor comfort for a softer signal, and the sharp ones trade flavor comfort the other way.
Form: whole kernel vs ground powder
Whole kernels give you a count — three a day, ten a day, whatever your routine is — and they keep longer in a sealed bag because the seed coat is intact. Powder is measured in scoops instead, mixes straight into smoothies and salads, and pulls double duty in skincare because it works as a natural exfoliant. Pick the form that matches how you actually use it; a whole kernel you never crack open is no better than a powder you never scoop.
