Below we take an in-depth look at Optimum Nutrition Opti-Women, to see what benefits this supplement offers consumers.
Optimum Nutrition Opti-Women is advertised as a multi-vitamin and mineral supplement designed specifically with women, but the ingredients list also features a number of different herbs as well. Chasteberry, one of the herbs that are used in this supplement, could reduce the effectiveness of the contraceptive pill, with some consumers of this product reporting changes in their menstrual cycle and spotting whilst taking this product.
Out of the thousands of customer reviews for this product, some reviewers have reported a range of side effects.
Numerous customer reviews mention that their urine becomes a bright yellow/neon yellow colour when taking this supplement. This is caused by the incredibly high Riboflavin (vitamin B2) content of this supplement, as the excess Riboflavin is expelled from the body via urine.
Other side effects reported by reviewers include headaches, heartburn, hot flashes, breakouts and acne, migraines, fatigue, night sweats, changes in menstruation (prolonged duration and heavier flow), nausea, vomiting, dizziness, a decline in sleep quality, mood swings, bloating, diarrhoea, brain fog, and itchy skin.
Worryingly, Chasteberry (Vitex agnus-castus) and Dong Quai could both reduce the effectiveness of the contraceptive pill. There is no warning about this on the product label or on the sales website.
Optimum Nutrition Opti-Women can be purchased from the official Optimum Nutrition website. A bottle of 60 capsules costs $14.99, and a bottle of 120 capsules costs $25.99. Delivery charges may also apply.
Overall, we are far from impressed by Optimum Nutrition Opti-Women. The list of side effects reported by consumers is long and varied. Two of the ingredients, Chasteberry, and Dong Quai, could reduce the effectiveness of the contraceptive pill; it is incredibly irresponsible of the manufacturers to not feature any kind of warning about this on the product label or sales websites, especially as this product is intended specifically for women. Although it is described as a multivitamin, it contains numerous herbal ingredients; these appear to be the cause of many of the side effects reported by consumers. The manufacturers do not even make it clear what the supposed benefits of these additional herbs and plant extracts are. Although the product is relatively cheap for supplements in general, the daily dosage of two capsules pushes up the cost per serving and makes this quite expensive for a multivitamin supplement.
The product is not covered by a money-back guarantee; the Optimum Nutrition returns policy covers opened bottle if less than 25% of the bottle has been used, and the returns policies of third-party retailers may vary.
Overall, we do not recommend Optimum Nutrition Opti-Women to our readers.

Optimum Nutrition Opti-Women is a multi-vitamin and mineral supplement designed for women, that also features some added herbal ingredients. The manufacturers do not describe the purposes of the added herbal ingredients, but describe them as “speciality” ingredients. Dong Quai and Chasteberry can both interfere with the effectiveness of the oral contraceptive pill, and can affect hormone levels.
Optimum Nutrition Opti-Women is manufactured by Optimum Nutrition, an American company who are based in Downers Grove, Illinois. They can be contacted using the information on their official website, or using any of their social media pages, which are all active and maintained. Optimum Nutrition pride themselves on maintaining a “Gold Standard”, with strict standards for “ingredients selection, quality control, lab testing and manufacturing processes”.
Directions for use are as follows:
Take two capsules per day
The manufacturers provide the following description of the product’s benefits:
- FEMALE-SPECIFIC MULTIVITAMIN – advanced formula to help support the overall health and active lifestyle of women*
- 23 VITAMINS AND ESSENTIAL MINERALS helps provide the body with key nutrients*
- 17 SPECIALTY INGREDIENTS – aids in creating a comprehensive and multifaceted multivitamin for the active woman
- 600MCG FOLIC ACID; 18MG IRON
- AVAILABLE IN 60 AND 120 CAPSULE BOTTLES – Vcaps used are Vegetarian Society approved
As a multivitamin, this product should work as described. The amounts of many of the vitamins are incredibly high; hundreds of customer reports of neon yellow urine show that the body cannot absorb the incredibly high dosage of Riboflavin, and excess amounts are expelled in the consumer’s urine. It is likely that this also applies to other vitamins in this blend as well.
The manufacturers do not actually specify that the intended purpose or benefits are of the additional 17 “speciality” ingredients, beyond stating that they are “for the active woman”. It is difficult therefore to establish whether this product actually ‘works’.
There are numerous reviewers who experienced a range of unpleasant side effects.
The ingredients found in Optimum Nutrition Opti-Women are detailed below. The ingredient quantities provided are per serving of two capsules.
There are numerous ingredients found in this supplement that could potentially cause a range of side effects.
Worryingly, Chasteberry (Vitex agnus-castus) and Dong Quai could reduce the effectiveness of the contraceptive pill. There is no warning about this on the product label or on the sales website. There are also several ingredients that may mimic oestrogen in the body, making this supplement unsuitable for anyone who has or had breast cancer or other oestrogen-related cancers.
Horse chestnut extract can cause dizziness, headache, stomach upset, and itching. Unprocessed horse chestnuts cannot be eaten as they are poisonous.
Garcinia Cambogia can cause some side effects including nausea, digestive tract discomfort, and headache. Its long-term safety is unknown, as clinical studies typically focus on the short-term use of up to 12 weeks.
Uva Ursi is a laxative, and so could increase bowel movements, and could cause diarrhoea, stomach pains and cramping. Long-term use of laxatives can cause dependence. In some cases (especially when dehydrated), the use of laxatives can actually cause or worsen constipation. Uva Ursi can cause vomiting and can turn urine a greenish-brown colour. Taking Uva Ursi regularly long-term or taking very high doses can cause liver damage, respiratory problems, vision problems, convulsions, and even death.
Not suitable for pregnant or breastfeeding women. Not suitable for anyone under the age of 18. Not suitable for anyone who uses the contraceptive pill, as Chasteberry could lower its effectiveness. If you have or have had breast cancer or ovarian cancer, consult your doctor before purchase. If you are unsure about the suitability of this supplement for you, consult your doctor before purchase.
There are thousands of customer reviews for this supplement across the numerous online retailers that stock it.
