What Is Soursop?
Soursop (Annona muricata), also known as graviola, guanábana, or Brazilian pawpaw, is a tropical fruit native to Central America, South America and the Caribbean. The fruit grows on a small evergreen tree and has a distinctive spiky green exterior with soft, white, fibrous flesh inside.
Soursop has been consumed as a food and used in traditional practices across Latin America, the Caribbean and parts of Africa and Southeast Asia for centuries. The fruit, leaves, bark and roots have all been used in various traditional applications.
Key bioactive compounds: The most notable constituents in soursop are acetogenins — a class of long-chain fatty acid derivatives found almost exclusively in the Annonaceae plant family. Soursop contains over 100 identified acetogenins, making it one of the richest natural sources of these compounds. Other constituents include alkaloids, phenols, flavonoids, vitamin C, B vitamins, potassium, magnesium and iron.
What Are Soursop Drops?
Soursop drops are liquid supplements that deliver soursop (graviola) extract in a concentrated, sublingual format. Unlike capsules or tablets, liquid drops are placed under the tongue or added to water, which allows for faster absorption through the mucous membranes.
Most soursop drops use an extraction process that concentrates the bioactive compounds from soursop leaves and fruit into a small-volume liquid. This means a single dropper can deliver the equivalent of several hundred milligrams of soursop extract.
Soursop drops and graviola drops are the same thing — soursop and graviola are different names for the same plant (Annona muricata).
The most studied class of compounds in soursop. Long-chain fatty acid derivatives found almost exclusively in the Annonaceae plant family. Extensively characterised in laboratory studies published in the Journal of Natural Products and Phytochemistry.
Soursop naturally contains vitamin C (~20mg per 100g fresh fruit). EFSA recognises vitamin C as contributing to normal immune function and the protection of cells from oxidative stress. Many formulas add acerola cherry for extra vitamin C.
One of nature's richest sources of vitamin C, commonly combined with soursop in UK supplement formulations. Adds genuine nutritional value beyond the soursop base extract.
One of the most studied botanical compounds in the world. Included in some soursop formulas as a complementary ingredient. Contains curcumin, which has been the subject of thousands of published studies.
Soursop Drops Benefits: What the Research Says
Soursop has been the subject of significant scientific interest, particularly over the past two decades. It is important to note that the majority of research has been conducted in laboratory (in vitro) and animal studies. Human clinical trials are limited, and more research is needed before definitive conclusions can be drawn.
📄 Published Research on Soursop
Acetogenins: Over 100 acetogenins have been identified in various parts of the soursop plant. These compounds have been extensively characterised in laboratory studies, with research published in the Journal of Natural Products, Phytochemistry and the Journal of Ethnopharmacology.
Antioxidant properties: Several laboratory studies have measured the antioxidant capacity of soursop extracts using standard assays (DPPH, ABTS, FRAP). A 2015 study published in Food Science and Technology measured significant antioxidant activity in soursop leaf extracts.
Important note: Most research is preclinical. Translating laboratory findings to real-world supplement use requires caution. The traditional use history is extensive, but clinical trials in humans are still limited.
Traditional Use Across Cultures
Soursop has a long history of traditional use across multiple continents. In the Caribbean, soursop leaves have been used to make teas for centuries. In Brazil, graviola is one of the most commonly consumed tropical fruits and has been used in traditional practices for generations. In Nigeria and other West African countries, various parts of the soursop plant feature in traditional herbal preparations.
How to Take Soursop Drops
Choose Your Method
Sublingual (recommended): Place drops under the tongue and hold for 30-60 seconds before swallowing. This allows absorption through the mucous membranes — the fastest delivery route. In water or juice: Add drops to a glass of water, juice or smoothie if you find the taste too strong.
Dosage
Most products recommend 1-2 dropperfuls per day, providing 1000-2000mg of soursop extract equivalent. Always follow the specific dosage instructions on your product, as concentrations vary between brands.
Timing
Take at any time of day — most people take them in the morning with or after breakfast. Taking with food may help absorption and reduce any chance of stomach discomfort. Consistency matters more than timing.
Be Consistent
Supplements work cumulatively. Most people who report noticeable changes do so after 2-4 weeks of consistent daily use. Don't expect overnight results — daily consistency is key.
Soursop Drops vs Soursop Capsules
| Factor | Liquid Drops | Capsules |
|---|---|---|
| Absorption | Sublingual — faster through mucous membranes | Digestive — through the stomach |
| Dosing | Adjustable — half dropper to full dropper | Fixed — 1 or 2 capsules |
| Taste | Tart, slightly bitter (natural) | No taste |
| Portability | Glass bottle — less portable | Easy to carry and take on the go |
| Swallowing | No swallowing required | Requires swallowing capsules |
| Additional ingredients | Often includes acerola cherry, vitamin C, turmeric | Varies by brand |
The choice between the two comes down to personal preference. Neither format is inherently superior — the quality of the extract inside is what matters.
What to Look For When Buying Soursop Drops
Quality Buying Checklist
- Extract strength per serving — check the total soursop extract in milligrams. Products range from 500mg to 2000mg per serving. Higher concentrations deliver more extract per dropper
- Correct species: Annona muricata — the supplement should clearly state it uses soursop/graviola. Some products use related Annonaceae species with different compound profiles
- Extraction method — cold extraction and ethanol extraction preserve bioactive compounds. Water-based extraction may be less effective at extracting fat-soluble acetogenins
- Third-party tested — independent testing (e.g. Eurofins) verifies contents and checks for heavy metals, pesticides and microbial contamination. Especially important for botanical supplements sourced from tropical regions
- Complementary ingredients — acerola cherry (natural vitamin C), turmeric (curcumin), and added vitamin C can genuinely enhance the formulation
- UK-manufactured in GMP facilities — certified manufacturing standards ensure consistency and quality control
