NOW Foods Tribulus Extreme 90 Veg Capsules

What it is

NOW Foods Tribulus Extreme is a dietary supplement sold as a bottle of 90 veg capsules, and its Supplement Facts panel lists five named botanicals rather than a single herb. The serving size printed on the panel is 2 veg capsules, and the panel states 45 servings — the figure that 90 capsules divide into at two per serving. The product belongs to the NOW Sports range, and the bottle is manufactured by NOW Foods of Bloomingdale, Illinois.

Each 2-capsule serving carries 1 g (1,000 mg) of Tribulus Extract Complex alongside four further botanical entries; adding the five printed figures together gives 1,480 mg of listed actives per serving. On this store the product is filed under Sports Nutrition.

What's inside

The panel names five plants, and it names a plant part for every one of them — a detail worth reading, because the part used is often what distinguishes one botanical preparation from another.

• Tribulus Extract Complex (Tribulus terrestris), fruit and aerial parts — 1 g (1,000 mg). Tribulus terrestris is a low, spreading plant of warm, dry ground, long established in traditional herbal practice across the Mediterranean, South Asia and China. "Aerial parts" is the standard botanical term for everything the plant grows above the soil — stems, leaves and flowers — so this entry is drawn from the fruit together with that above-ground material. General background on how plant-based supplements are prepared and labeled is set out in the NIH Office of Dietary Supplements background sheet on botanical dietary supplements, which does not refer to this product.
• Organic Raw Maca Root (Lepidium meyenii), 6:1 concentrate — 400 mg. Maca is a root crop of the high Peruvian Andes, grown at altitude and eaten there as an ordinary food. The "6:1" is the concentration ratio the label commits to: six parts of starting root material reduced down to one part of finished concentrate. The 400 mg is the weight of that concentrate as it goes into the capsule, not the weight of the raw root it came from.
• Epimedium Extract Complex, aerial parts — 20 mg. Epimedium is a shade-loving perennial of East Asian woodland. This entry is drawn from the aerial parts — the above-ground growth — and the panel lists it at 20 mg.
• Green Tea Extract (Camellia sinensis), leaf — 30 mg. Green tea comes from the leaves of Camellia sinensis, the same evergreen shrub that produces black and oolong tea; the difference between them is how the picked leaf is handled afterwards, not the species. The NCCIH overview of green tea gives general background on the plant and is not a statement about this supplement.
• Damiana (Turnera diffusa), leaf — 30 mg. Damiana is a small aromatic shrub native to Mexico, Central America and the Caribbean, where the leaf has a long history in regional herbal tradition. It is the one row on this panel not described as an extract or a concentrate.

Three of the five rows are labeled "Complex" or "Concentrate". That wording describes the preparation rather than the raw herb, and the panel does not break those entries down any further, so the figure beside each one is the weight of the prepared material and nothing more precise can be read from the label. All five rows carry the footnote ** Daily Value not established, which means no federal reference intake has been set for these botanicals — not that the amount is unusual in either direction. For wider context on how herbal products are studied, the NCCIH maintains a herbs at a glance index.

The remaining ingredients are the capsule and its flow agents: hypromellose, which is the cellulose material the veg capsule shell is made from, plus maltodextrin (non-GMO), silicon dioxide and stearic acid from a vegetable source. The panel assigns no role to these, so neither do we.

How to use it

The label's suggested usage is: take 2 capsules daily with food. That is the whole of the printed instruction — the bottle gives no separate timing, no loading period and no alternative schedule. Storage is equally brief: store in a cool, dry, dark place after opening.

At the printed serving, a 90-capsule bottle works out to a 45-day supply, which matches the 45 servings stated on the panel. The capsules are veg capsules, so they can be taken with water in the ordinary way.

Who it's for

This is a product for adults, and the bottle's own caution states "For adults only". It will suit someone who already knows they want a multi-botanical capsule rather than a single-herb one: the panel runs to five named plants with an individual amount printed beside each. On this store it is also filed under Health & Wellness.

The capsule shell is hypromellose, a plant-derived cellulose rather than gelatin, and the bottle front carries a "V Vegan" mark along with a "Non-GMO" mark. The bottle itself is printed as being made from 100% PCR (post-consumer recycled) resin.

Good to know

The printed caution reads: for adults only; not recommended for pregnant or nursing women; consult a physician if taking medication or if you have a medical condition; discontinue use if rash or itching occurs; keep out of reach of children. The bottle also notes that natural color variation may occur in this product.

The allergen statement on the panel reads: not manufactured with yeast, wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients; produced in a GMP facility that processes other ingredients containing these allergens. The origin statement reads "Made and quality tested in the USA with globally sourced ingredients", and a GMP Quality Assured roundel is printed beside the barcode.

If you take prescription medication or have an existing condition, speak to a licensed healthcare professional before starting any supplement; the NCCIH publishes general guidance on dietary and herbal supplement safety that applies to supplements generally rather than to this one.

Frequently Asked Questions

How many capsules are in a bottle, and how long does one bottle cover?

The bottle holds 90 veg capsules. At the label's suggested usage of 2 capsules daily, that is a 45-day supply, and the panel independently states 45 servings.

What does "6:1 Concentrate" mean on the maca row?

It is a concentration ratio: six parts of starting root material are reduced to one part of finished concentrate. The 400 mg printed beside Organic Raw Maca Root is the weight of that concentrate in a 2-capsule serving, not the weight of the raw root used to make it.

What is the capsule shell made of?

The shell is hypromellose, listed on the panel as "cellulose capsule". The other listed ingredients are maltodextrin (non-GMO), silicon dioxide and stearic acid from a vegetable source.

Does the label list allergens?

Yes. The panel states the product is not manufactured with yeast, wheat, gluten, soy, milk, egg, fish, shellfish, tree nut or sesame ingredients, and that it is produced in a GMP facility that processes other ingredients containing those allergens. Anyone with a known allergy should read the full panel on the bottle before use.
