Coast Science describes itself as a company focused on supporting a healthy reproductive function and also providing fertility support. It claims to deliver products aimed at maintaining reproductive wellness and supporting the physiological processes involved in sexual health.
The company emphasizes combining multiple nutrients in its formulations to support cellular function, egg and sperm quality, hormonal balance, antioxidant protection, and metabolic activity.
This review examines Coast Science, covering its advantages, potential limitations, and insights from real user experiences. It also highlights key factors for evaluation, which may help you understand what you should consider before trying the brand.
Founded by Bruce Thomsen, Coast Science claims to provide different products to support reproductive health. The company has been operating for over 20+ years and emphasizes manufacturing all of its products in the United States.
The brand’s product range includes formulations intended for reproductive and hormonal support, such as Fertile One® PC 600 for preconception nutritional support, Fertile One® PCOS 600 for women with polycystic ovary syndrome, MFSg6 for male reproductive health, and DHEA Derived from Wild Yam Extract for hormonal balance.
Coast Science also claims to use trademarked ingredients like Quatrefolic®, AlgaeCal®, and ChromeMate®, along with antioxidants such as CoQ10 and PQQ, which are included in its different formulations.
Fertile One PC 600 might support egg and embryo quality, reduce oxidative stress, promote mitochondrial function, and potentially help prevent nutrient deficiencies that can impact fertility. It contains an extensive range of vitamins, minerals, and antioxidants.
Among the key ingredients is CoQ10 in the ubiquinol form, which may support mitochondrial function that helps produce energy needed for division, repair, and development. CoQ10 is considered especially important for egg health because of its role in energy metabolism.
The formula also contains pyrolloquinoline quinone, resveratrol, DHA from algal oil, and D-chiro-inositol. These compounds are antioxidants and cellular support agents that may help protect eggs and embryos from oxidative stress and improve cellular signaling pathways.
Folate is included in the form of Quatrefolic®, a biologically active version of 5-methyltetrahydrofolate (5-MTHF). It may help in preventing neural tube defects and supporting proper fetal and placental growth, making it a key nutrient for preconception care.
The product also provides vitamins A, C, D, and E, all of which aid in immune function, antioxidant defense, and cell growth. The B-vitamin group has thiamin, riboflavin, niacin, vitamin B6, vitamin B12, pantothenic acid, and biotin, which support energy metabolism and neurological function.
Minerals included in the blend are calcium, magnesium, zinc, selenium, copper, manganese, and chromium, many of which are provided in chelated forms that the body could more easily absorb. These nutrients contribute to immune health, hormone regulation, antioxidant activity, and cell structure. Additional supportive compounds include N-acetyl cysteine, which may reduce oxidative stress in cells.
PCOS 600 may support fertility through its vitamins, minerals, antioxidants, and plant extracts that aim to improve ovulatory function, insulin sensitivity, and follicular development. The product contains CoQ10 that functions to support mitochondrial function and may also help improve egg health. It also includes PQQ, another antioxidant that might reduce oxidative stress and inflammation.
Several other ingredients, like gymnema sylvestre, a plant extract, are described as providing an anti-diabetic effect that helps regulate insulin levels. D-chiro-inositol is included to improve the action of insulin, which may promote more regular ovulation and help reduce testosterone levels. S-acetyl-glutathione antioxidant might help protect egg quality and may support ovulation function.
DHEA, derived from Wild Yam Extract, contains 25 mg of 99% pure DHEA (dehydroepiandrosterone) per capsule. According to the makers, DHEA might help in maintaining a healthy hormone balance.
DHEA might help in improving egg quality and potentially boost sex drive. It could also help in improving ovarian function and aid in maintaining a healthy metabolic function.
Coast CoQ10 might aid in cellular energy production by helping the mitochondria in your cells generate ATP. It also functions as an antioxidant, which helps reduce oxidative stress, supports cardiovascular function, maintains heart health, and promotes energy levels.
CoQ10 is involved in many key biological processes, including fertility, protein production, food digestion, and muscle contraction. It may improve female egg quality and has been shown to support sperm count and motility.
Generation M™ Menopausal Support might provide support for peri-menopausal and menopausal women. It contains a blend of antioxidants that may protect cells from oxidative stress.
Nutrients like vitamin A (from beta-carotene), vitamin C, vitamin E, selenium, CoQ10, PQQ, and S-Acetyl-Glutathione may work together to neutralize free radicals, promote tissue repair, and support the health of the heart, skin, and other vital organs.
Bone and mineral health is supported through calcium, magnesium, vitamin D3, vitamins K1 and K2, copper, manganese, and zinc. These nutrients might help maintain strong bones, regulate mineral balance, and support connective tissue and enzymatic processes essential for skeletal strength, which is particularly important during menopause.
Energy metabolism and nervous system function are aided by the B vitamins, such as B1, B2, B6, B12, niacin, pantothenic acid, biotin, and folate. These nutrients are critical for converting food into energy, supporting brain and nerve function, maintaining cognitive health, and regulating mood.
Generation M™ Menopausal Support also contains iodine, chromium, Gymnema sylvestre, and D-Chiro-Inositol. These compounds may support thyroid function, regulate blood sugar, and maintain metabolic health. It also has DHA/EPA (omega-3 fatty acids), CoQ10, and vitamin E, which may promote healthy cholesterol levels, support cardiovascular function, and enhance brain health.
Skin, hair, and tissue health might be supported by Generation M™ Menopausal Support’s vitamin A, biotin, zinc, selenium, and vitamin C content, which contribute to skin elasticity, hair strength, and wound healing.
MFSg6 might help optimize sperm parameters and enhance male reproductive ability. The company states that this formula focuses on sperm count, motility, morphology, DNA integrity, and sexual health.
Minerals in the formulation include calcium from AlgaeCal®, iron, iodine, magnesium, zinc, selenium, copper, manganese, chromium, and molybdenum. These nutrients may work together to support metabolic function, hormone balance, nerve function, tissue maintenance, and enzymatic processes that promote reproductive health.
The product includes a broad spectrum of vitamins, including vitamin A from beta-carotene, vitamin C, vitamin D3, vitamin E, a blend of vitamins K1 and K2, B-complex vitamins such as B1, B2, B3, B6, B12, biotin, folate, and pantothenic acid.
MFSg6 also contains a proprietary blend of compounds that the brand claims support antioxidant protection, energy production, and reproductive function. This blend includes CoQ10, DHA and EPA sourced from deep-sea fish oil, resveratrol, quercetin, D-Chiro-Inositol, Pyrroloquinoline Quinone (PQQ), S-Acetyl-Glutathione (Emothion™), and boron.
According to Coast Science, these ingredients help maintain DNA integrity in sperm, support mitochondrial function, and contribute to cardiovascular and endothelial health, which may indirectly support reproductive ability.
Men’s Generation M Support may help maintain heart, skin, and lung health, boost energy to reduce fatigue, counteract oxidative stress, and support cognitive function. It is also intended to promote emotional well-being, sexual health, and healthy aging, and may help with erectile problems.
The supplement features an antioxidant proprietary blend with CoQ10, DHA and EPA, inositol, N-Acetyl Cysteine (NAC), choline, Gymnema sylvestre, quercetin, D-Chiro-Inositol, and pyrroloquinoline quinone. These compounds may provide antioxidant protection, help maintain cellular energy, support cardiovascular health, and contribute to sexual health, and potentially provide cognitive support that could boost focus.
Coast Science claims that all of its supplements are manufactured entirely in the United States. It may resonate with consumers who associate domestic manufacturing with higher safety standards, rigorous quality control, and ethical practices.
The brand also emphasizes that every step of production, from sourcing the materials to packaging the product, is closely monitored. This may highlight that the products are premium, consistent, and reliable.
Coast Science’s organic farm in San Diego highlights that their ingredient sourcing is U.S.-based, adding a layer of transparency and traceability. This combination of domestic production, high-quality ingredients, and strict manufacturing highlights the brand’s credibility, which could be a positive factor if you prioritize national origin and safety in your products.
Coast Science reports over 20 years of experience in the fertility and nutritional supplement industry. The company describes a history of providing fertility-focused nutraceuticals in the infertility sector. Its products are sold in 60 countries, including partnerships with professional organizations such as the American Society for Reproductive Medicine (ASRM), European Society for Human Reproduction and Endocrinology (ESHRE), and Canadian Fertility and Andrology Society. This combination of longevity, international presence, and professional engagement represents established experience and credibility. These aspects can help you understand the potential reliability of product availability, the extent of regulatory oversight, and the professional standards the brand follows, which may enhance your confidence while exploring its products.
Coast Science emphasizes that its products are manufactured in U.S. facilities following Good Manufacturing Practices. However, the brand does not provide evidence of independent third-party lab testing to verify potency, purity, or contaminant level that applies across its entire product line. This includes widely used supplements such as Fertile One PC600, which contains folate, antioxidants, and herbal extracts, and MFSg5, which includes zinc, selenium, and L-carnitine.
Without external verification, it is unclear whether the actual ingredient levels match the label or whether the products are free from heavy metals and other contaminants, particularly given the use of marine-derived or herbal ingredients.
The lack of third-party testing means you cannot be completely confident that its products contain the exact dosages promised or that it is free from impurities. This could affect the supplement’s effectiveness in supporting fertility goals, and in rare cases, expose you to unwanted contaminants. The absence of independent validation creates uncertainty about product quality and consistency, which may influence both safety and the expected outcomes of supplementation.
While evaluating the user experience for Coast Science’s various formulations, we looked for real user responses on Amazon to understand how the products perform in practice.
PC 600 has received generally strong feedback, with a rating of around 4.4 out of 5 stars from over 199+ reviewers. Most users highlighted support for fertility and overall well-being.

Coast Science’s supplements are generally regarded as supportive for fertility support and preconception health, with most people expressing satisfaction. Positive experiences emphasize convenience and well-being benefits. However, recurring concerns include dosage, cost, taste or smell of certain capsules, and dietary sensitivities.
While evaluating Coast Science, we looked at publicly available platforms such as the Better Business Bureau (BBB) to assess the company’s reputation. The BBB records showed that Coast Science has not been accredited and currently holds a BBB rating of D-. The company has received a small number of complaints in the past. The complaints have mainly involved delivery delays and difficulties with product returns.
Customers reported that orders had not arrived as expected, and that attempts to contact the company for refunds or support had gone unanswered. One complaint noted that only a partial shipping refund was provided, while the underlying product issue remained unresolved.
The company has not fully responded to these complaints, and the BBB records indicate that both issues remain unresolved. This highlights recurring challenges with communication and customer service.
Areas for improvement include more reliable shipping and delivery processes, improved responsiveness to customer inquiries, and stronger quality control and support systems to handle returns or refunds efficiently.
While Coast Science has a low volume of complaints, the unresolved issues and recurring patterns in customer feedback indicate notable areas where the company could improve its service and reliability.

This highlights Fairhaven’s broader scope across the reproductive lifecycle, whereas Coast Science concentrates specifically on fertility and hormonal wellness.
Coast Science provides a focused lineup of fertility and hormonal support products that may optimize reproductive health. It highlights high-quality, bioavailable ingredients that may provide support in maintaining egg and sperm quality, hormonal balance, and cellular wellness.
However, its products are relatively high-priced, some require refrigeration, and the brand does not offer independent third-party testing to verify potency or purity. There were also some concerns regarding its customer service in the past. These factors may impact convenience, accessibility, and confidence in consistent product quality, depending on your personal needs and priorities.
The brand delivers a structured, research-backed approach to reproductive wellness. However, how well it might fit depends on how its specialized formulations, logistical considerations, and cost align with your priorities.
