Griffonia Simplicifolia: 5-HTP Label Guide.

The short answer: Griffonia simplicifolia is a woody legume shrub from West and Central Africa, and its seeds are what supplement 5-HTP (5-hydroxytryptophan) is commercially extracted from. On a Supplement Facts panel, find the 5-HTP milligrams first, then the source line, such as "from Griffonia simplicifolia seed extract." Our 5-HTP Capsules print 200 mg of 5-HTP per 2-capsule serving, alongside 450 mg of calcium.

Key takeaways

• Griffonia simplicifolia seeds are used to produce commercial 5-HTP, since making it from tryptophan by chemical methods isn't easy.
• Betterly's 5-HTP Capsules list 200 mg of 5-HTP plus 450 mg of calcium (35% of the Daily Value) per 2-capsule serving.
• A griffonia source line names the plant and the part used, not the extract's purity, the seeds' origin or whether bacterial 5-HTP was added.
• 5-HTP can also sit last in a proprietary blend with no amount printed, as it does in our 10 mg melatonin capsule.
• If you take a medicine that affects serotonin, get your prescriber's okay before any griffonia or 5-HTP product.

Our own interest, up front: two Betterly bottles contain 5-HTP from griffonia seed, and only one prints how much. We'd like your order, so weigh that. What we offer is a line-by-line reading of both real panels, a method that works on any brand's bottle.

What is Griffonia simplicifolia?

Griffonia simplicifolia is a perennial woody shrub in the legume family that grows in the tropical rain forests of West and Central Africa, and its seeds contain 5-HTP.

That description comes from a 2019 Molecules paper, Chemical Characterization and DNA Fingerprinting of Griffonia simplicifolia Baill.. The authors list cultivation sites in Ghana, Ivory Coast and Togo.

Griffonia is the genus, and simplicifolia is the specific epithet. The NIH Office of Dietary Supplements (ODS) says in its fact sheet on botanical supplements that botanists combine the two to form a species name.

5-HTP was the main compound in the seeds' soluble fraction, at about 16% of seed weight. The authors add that published figures, made with different lab methods and solvents, run from 10% to 20%.

What does "from Griffonia simplicifolia seed extract" mean on a label?

"From Griffonia simplicifolia seed extract" is a source line: it says the 5-HTP listed above it came from griffonia seeds, not how pure that extract was.

Griffonia and 5-HTP aren't the same thing. Griffonia is the plant, and 5-HTP is one compound its seeds contain. According to ODS, one chemical can be pulled out of a plant and sold on its own as a dietary supplement, usually as a capsule or tablet. For 5-HTP, that plant is griffonia, because the Molecules authors say making 5-HTP from tryptophan by chemical methods isn't easy.

21 CFR 101.36, the FDA's rule for Supplement Facts panels, lets a label name a source ingredient in parentheses after the ingredient, starting with "as" or "from." It also says a botanical source has to name the plant part it came from. Our 5-HTP panel uses both words:

• "Calcium (as calcium carbonate)" names the compound that supplies the mineral.
• "5-Hydroxytryptophan (from Griffonia simplicifolia seed extract)" names the plant, the part used (seed) and the form (extract).

A source line can't tell you how the extract was made, how concentrated it was, where the seeds grew, or whether anything was added to it. For griffonia, that last gap matters, as the side-effects section explains.

That applies to us. Our source line is reproduced unchanged from the manufacturer's specification. Betterly doesn't make its own capsules and hasn't audited its supplier, as our quality page says, so we can't vouch for anything beyond the printed line.

How much 5-HTP per day does a label list, and what does that number mean?

5-HTP has no federal daily amount that we could find, so any label's figure is that product's own; Betterly's 5-HTP Capsules print 200 mg in each 2-capsule serving.

That serving is two capsules taken once a day, so each capsule holds 100 mg. In the % Daily Value column, two asterisks point to "Daily Value not established." Section 101.36 requires that symbol for any ingredient without a federal reference amount, so it's neither a warning nor a quality badge.

Under the same regulation, the milligrams beside an ingredient like 5-HTP must be the weight of that ingredient, not of its source. So when the row is named 5-Hydroxytryptophan, 200 mg means 200 mg of 5-HTP.

Some panels name the extract instead. Picture a row reading "Griffonia seed extract 250 mg." That figure weighs the dried extract, and the 5-HTP inside is a smaller share you can't know unless the panel lists it underneath or prints a percentage. Our guide to what "standardized extract" means shows how to turn a percentage into milligrams.

Griffonia percentages need care, too. The Molecules team found that natural seed extract rarely went above 20% 5-HTP on a dry-weight basis, and they said claims of 98% should be carefully considered. As a test, they analyzed one commercial griffonia extract sold as 95% 5-HTP. It measured about 65%.

Only a row naming 5-HTP with its own milligrams tells you how much you're swallowing.

From our shop: 5-HTP Capsules — the 5-HTP amount stated outright, 200 mg from griffonia seed extract per 2-capsule serving, plus 450 mg of calcium.

How do you spot 5-HTP hidden in a proprietary blend?

To spot hidden 5-HTP, scan every blend for three names, 5-HTP, 5-hydroxytryptophan and Griffonia simplicifolia, because each can point to the same seed compound.

A proprietary blend gives one combined weight, and under 101.36 its ingredients run from heaviest to lightest with no individual amounts. Our plain-English guide to proprietary blends walks through the format.

Our own example is the 10mg Melatonin Sleep Capsules. Its panel shows 10 mg of melatonin, then a 905 mg Sleep Formula Proprietary Blend, both per 2-capsule serving. The blend names 14 ingredients, and the last reads "5-HTP (Griffonia simplicifolia)(seed)." Same plant, same seed, no milligrams. Last place only tells you it weighs no more than anything listed above it.

Once you find it, look for three more things:

1. Tryptophan in the same blend. Ours lists L-tryptophan first, and it's the ingredient a federal serotonin warning names, as the side-effects section explains.
2. St. John's wort. It's in this blend too, and it's worth showing a pharmacist if you take any prescription.
3. A second 5-HTP bottle. Adding our 5-HTP Capsules would stack a known 200 mg on an unknown share, and our 5-HTP vs L-tryptophan comparison works out the most that share could weigh.

The same scan works across our Sleep & Stress Relief collection before you combine any two products.

From our shop: 10mg Melatonin Sleep Capsules — for adults who want melatonin and griffonia 5-HTP in one bedtime formula: 10 mg of melatonin per 2-capsule serving, with 5-HTP listed last in a 905 mg blend.

Why does a 5-HTP capsule list 450 mg of calcium?

Betterly's 5-HTP Capsules list 450 mg of calcium per 2-capsule serving, 35% of the Daily Value. The label doesn't say why it's there, so we won't guess.

The weight rule from the dosage section applies here, and 101.36 uses this exact pairing as its example: the weight of calcium, not of calcium carbonate. So the carbonate that supplies 450 mg of calcium weighs more.

This line counts toward the same daily total as calcium from food, a multivitamin or a calcium pill. The side-effects guide linked below lists the NIH's calcium upper limits by age.

What are the known Griffonia simplicifolia side effects?

Griffonia's side effects depend on what the extract carries: 5-HTP, which NCCIH lists among supplements with sedative effects, plus any by-products left by how that 5-HTP was made.

The National Center for Complementary and Integrative Health (NCCIH) makes that sedative point on a page on sleep and complementary health approaches, adding that how 5-HTP works is unclear. The same page warns that L-tryptophan supplements may cause life-threatening serotonin toxicity when used with medicines that affect serotonin metabolism. The Molecules authors write that an enzyme converts 5-HTP into serotonin (5-HT) in the central nervous system. So we hold griffonia products to that rule too: no serotonin-affecting medicine alongside them without your prescriber's okay.

The by-product question belongs to griffonia. The Molecules authors describe a common shortcut: topping up a griffonia extract with 5-HTP made by genetically engineered bacteria. They call two tryptophan by-products of that route, 1,1′-ethylidenebis(L-tryptophan) and 3-(phenylamino)alanine, neurotoxic compounds and typical markers of bacterial fermentation. Their own seeds contained neither, but the commercial extract sold as 95% 5-HTP carried the first at about 6 mg per gram. The same NCCIH page says analyses of several 5-HTP sources have shown no toxic contaminants like those tied to L-tryptophan, and no other significant impurities. The Molecules findings describe what to watch for, not what every bottle contains.

No Supplement Facts panel lists compounds like these, ours included. ODS says it's difficult to determine a botanical product's quality from its label, and griffonia gives that warning a concrete shape.

What else does the back panel of a griffonia 5-HTP bottle tell you?

Beyond the Supplement Facts box, the back panel of Betterly's 5-HTP Capsules gives the daily directions, one firm limit, the bottle count and what the capsule is made of.

The label's suggested use is two capsules once a day, taken 20 to 30 minutes before a meal with an 8 oz (237 ml) glass of water. Here's how to read the rest:

• The last words of the directions, "or as directed by your healthcare professional," leave room for your provider to change the schedule, not for you to.
• The caution begins "Do not exceed recommended dose," which caps the day at two capsules.
• At 60 capsules and 30 servings, the bottle's count only adds up at one serving a day.
• Hypromellose is listed as the capsule, followed by microcrystalline cellulose and magnesium stearate. No gelatin appears on the list.
• The label's claims include gluten free and lactose free.

When don't you need a griffonia supplement?

You don't need a griffonia supplement whose label can't say what you'd get: a seed powder or extract with no 5-HTP milligrams printed gives you nothing to measure.

The same logic covers these cases:

• The panel says only "5-HTP," and the brand can't name its source when asked. Given the bacterial-route findings above, a named source is worth insisting on.
• You're counting on our 10mg melatonin capsules for a set amount of 5-HTP. Their blend gives griffonia no milligrams, so that panel can't promise one.
• You're mainly after calcium. A 5-HTP capsule is a roundabout source, since the 450 mg arrives with 200 mg of 5-HTP. Your pharmacist can help you weigh calcium on its own terms.

Who should check with a healthcare provider first?

A doctor or pharmacist should weigh in before any griffonia product if you take a prescription, are pregnant or nursing, are under 18, have a medical condition, or face surgery.

Our bottle's caution covers most of that list: "Consult a physician if pregnant, nursing, under 18, or have a medical condition." Surgery is our addition: if an operation is scheduled, list griffonia among your supplements for the care team.

If you take any prescription, ask whether it affects serotonin, since that's the concern behind the NCCIH warning above. Ask, too, whether the capsule's 450 mg of calcium should be taken apart from your other medicines.

FAQ: Griffonia seeds and 5-HTP

Does Griffonia simplicifolia have a common name?

Griffonia simplicifolia has no English common name in any of the sources we used, so labels, ours included, print the Latin name. You may also see Bandeiraea simplicifolia, which the 2019 Molecules paper calls an incorrect alternate name for the same plant.

Is all 5-HTP made from griffonia seeds?

Not necessarily. The 2019 Molecules paper says griffonia seeds are the commercial source because making 5-HTP chemically isn't easy, but engineered organisms can now make it from tryptophan, and bacterial 5-HTP is sometimes added to plant extracts. A label naming griffonia seed tells you the plant source. One that says only "5-HTP" leaves the origin open, so ask the brand.

Are griffonia seeds or seed powder the same as a 5-HTP supplement?

No, ground griffonia seed isn't the same as a 5-HTP supplement, because most of the seed is other material. In the seeds the Molecules researchers measured, 5-HTP was about 16% of the weight. A seed powder label gives the powder's weight, so unless it also prints a 5-HTP amount, you can't tell how much you'd get. Betterly doesn't sell griffonia seed or seed powder.

Can you take griffonia with other medicines?

Only with a pharmacist's or prescriber's okay based on the actual labels, because griffonia 5-HTP is easy to miss. In a blend it may be a single back-panel line with no milligrams. So the useful question for your pharmacist is whether any 5-HTP is acceptable with your medicines, not whether 200 mg is. Bring the bottles, not a list of names.

How long does griffonia take to work?

None of the sources we used gives a timeline for griffonia or 5-HTP, and our label doesn't set one. NCCIH says it's unclear how 5-HTP works, so any promised number of days would be a guess. The one-serving-a-day limit is the same in week one and week six, so a slow start isn't a reason to double up.
