Best Passionflower Supplements of 2026

The 700 mg figure on SOLARAY's bottle is the first thing you notice, and it is a different proposition from a concentrated extract. This is whole aerial passionflower rather than a standardized extract, so the dose is closer to the traditional powdered-herb approach. The bottle holds 100 vegan capsules, and the formula is Non-GMO Project certified and made in a GMP-certified facility.

For a shopper who wants a high-milligram, full-spectrum capsule, this is our pick. We like the 100-count bottle for a daily routine, and the vegan, non-GMO formula suits a broad range of shoppers. The trade-off is that 700 mg of whole herb and 350 mg of standardized extract are not interchangeable numbers; compare the form before you compare the milligrams. SOLARAY has been around for decades, and the simple single-herb formula is easy to slot into a routine. The 100-count bottle gives you a reasonable run before reordering, and the non-GMO certification is a useful quality signal. We did not find a major formulation complaint. What we did notice is how often whole-herb and standardized products get compared by milligram alone; they should not be. This one is for the shopper who wants the traditional, higher-milligram capsule and is comfortable reading the label that way. If you prefer a defined extract, NOW is the cleaner choice.

Organic certification is the reason to look at Oregon's Wild Harvest first. The passionflower aerial tops are certified organic, the capsules are vegan, and the formula is made without dairy or soy allergens. For a shopper trying to keep a clean-label supplement routine, that is a meaningful difference from a conventional capsule.

The 90-count bottle is a standard size, and the capsules are easy to keep in a daily rotation. We like that the brand makes the product in Redmond, Oregon, and verifies it non-GMO through an independent lab. The organic positioning comes at a premium compared with the conventional capsules here, so this is the bottle you choose when sourcing matters more than the lowest cost. The label is also free from dairy and soy, which helps if you are juggling allergen restrictions.

Our take: this is the capsule we choose when organic sourcing is the non-negotiable. It is a premium pick, and the 90-count bottle is a reasonable daily size. The clean-label appeal is real, but it is not a reason to overlook the price; this is a premium bottle in this group. We like that the brand is transparent about the Oregon production and third-party non-GMO verification, and the vegan capsule keeps the formula broadly usable. If organic is your line in the sand, this is the one. If you want a clearly standardized extract instead, NOW is the better fit; if you want the lowest-cost capsule, Horbäach is the practical choice.

The Horbäach bottle is the budget capsule in this group: 90 capsules, a simple single-herb formula, and a label that keeps the filler list short. It is gluten-free, non-GMO, and free of artificial colors and preservatives, which is more than you can say for some cheap capsules.

The catch is that the listing does not state a milligram strength. If you want to compare 250 mg, 350 mg, and 700 mg products, Horbäach makes that harder. We also like that the brand says the formula is laboratory tested, but the missing dose is the detail we noticed first.

Our take: this is the one to choose when you want a low-cost, no-frills capsule and you are comfortable starting with the label's serving direction. It is a good fit for a simple nightly routine, not for someone who wants a standardized extract with a number on the front. The 90-count bottle is a useful size for trying a capsule without committing to a bulk bottle, and the simple formula is easy to stack with a basic routine. We did not find a lot of formulation clutter here, which is the point. The missing milligram amount is the one thing that keeps it from being a universal budget pick: you can compare the price, but not the dose. If dose transparency matters, pay a little more for NOW or SOLARAY.

Nutricost's bottle is built around yield: 120 capsules, one capsule per serving, and a 375 mg 4:1 passionflower extract. That works out to a four-month supply at one capsule a day, which is the kind of math that makes a supplement easy to keep in the routine. We like the single-capsule serving and the third-party testing by ISO-accredited labs. For bulk-value shoppers, this is our pick.

The 4:1 ratio is not the same as a standardized percentage. It tells you how much raw herb went into the extract, not how much of a specific marker compound is present. That is not a problem if you want a straightforward extract at a low cost per serving, but it does make this harder to compare with NOW's 3.5% standardized capsule. We also noted that the label calls for one capsule, so the bottle lasts as advertised if you stick to that serving. The capsule count is the real advantage: 120 servings means fewer reorders and a lower cost per night than the 60- and 90-count bottles here. The bottle is also compact for a bulk supply, and the single-capsule serving keeps the routine simple. If you want a standardized extract, pay for NOW; if you want the lowest cost per night, this is the bottle.

Herb Pharm's passionflower comes as a 4-ounce liquid extract, and the serving math is the first thing that stands out: up to 168 servings per bottle. For someone who already likes tinctures, that makes the bottle a long-running staple rather than a weekly purchase. It is USDA organic, vegan, sugar-free, and made from Passiflora incarnata aerial parts.

The liquid format is flexible. You can measure drops into water or juice, and the bottle is easy to keep on a nightstand or in a kitchen cabinet. We appreciate that it is sugar-free and organic, which matters if you are avoiding added sweeteners or conventional herb sourcing.

The taste is the sticking point. This is a strong, bitter extract, and the alcohol base is noticeable. If you are sensitive to either, a glycerin-based alcohol-free tincture like Wild & Organic is the easier daily pour. We found the best approach is to dilute it in a few ounces of juice rather than take it straight.

Our take: this is the full-size tincture we recommend for people who want an organic liquid extract and do not mind a strong flavor. It is a premium bottle, but the serving count spreads the cost out. If you want alcohol-free, choose Wild & Organic; if you want capsules, stay with NOW.

Wild & Organic's tincture is alcohol-free and glycerin-based, which is the detail that separates it from the stronger-tasting liquid extracts here. The base gives it a naturally sweet taste, and the formula is USDA organic, vegan, and free from artificial additives. Each 2-ounce bottle has 85 servings, or about a 28-day supply at the label's three-times-daily serving.

We like this one for anyone who wants a tincture but does not want alcohol or a bitter pour. The dropper format is easy to measure, and the glycerin base makes it more approachable than an alcohol tincture, especially if you have tried one before and disliked the burn. We also appreciate that the organic claim is USDA certified rather than a vague natural label. The trade-off is the serving schedule: three times a day is a lot to remember, and the bottle empties faster than the 4-ounce Herb Pharm extract. If you prefer a once-nightly routine, a capsule is simpler. But for an alcohol-free tincture that is pleasant to take, this is our pick.

Puritan's Pride's 250 mg capsule is the lower-dose option in this group. That is not a knock: if you want to start with a smaller serving or you are sensitive to stronger extracts, a 250 mg capsule gives you more room to adjust than a 700 mg whole-herb dose.

The bottle holds 60 rapid-release capsules, so it is a smaller commitment than the 90- and 120-count bottles here. The formula is a single-herb passionflower extract, and the brand has been in the supplement business for decades. We like the rapid-release design for a nightly routine, though the 60-count bottle means you will reorder sooner.

The trade-off is transparency. The label gives you 250 mg of extract, but it does not standardize to a percentage the way NOW does. That makes it harder to compare against 350 mg standardized or 700 mg whole-herb capsules. If you want a defined marker, NOW is the clearer choice.

Our take: this is the capsule we choose for a gentle starting dose or a smaller bottle. It is a good fit for someone who wants to try passionflower without committing to a high-milligram serving. If you already know you want a full-size daily bottle, SOLARAY or Nutricost gives you more servings for the money.
