×This medicine has many beneficials.
✓This medicine has many beneficial effects.
"Beneficial" is an adjective, not a noun. It cannot be pluralized or used as a countable noun. You need to add a noun (e.g., effects, properties, aspects) after it.
×Reading is beneficial for your vocabulary.
✓Reading is beneficial to your vocabulary.
While both "to" and "for" can sometimes be used, "beneficial to" is more standard when referring to the recipient of the benefit (a person, skill, or thing that gains the advantage). "Beneficial for" is more often used with gerunds or to indicate purpose (e.g., beneficial for improving...). For direct recipients, "to" is preferred.
×This method is very beneficialer than the old one.
✓This method is more beneficial than the old one.
"Beneficial" is a long adjective (more than two syllables). Its comparative form is "more beneficial," not "beneficialer." Similarly, the superlative form is "most beneficial."
×The software runs beneficial.

"Beneficial" is an adjective and must modify a noun. To modify a verb (like "runs"), you need the adverb form "beneficially."
×The beneficial effects of sleep is well-known.
✓The beneficial effects of sleep are well-known.
The subject of the sentence is the plural noun "effects," so the verb must be plural ("are"). Do not be confused by the singular noun "sleep" in the prepositional phrase.
×He is a beneficial donor to the charity.
✓He is a beneficent donor to the charity.
"Beneficial" means "producing good effects." "Beneficent" means "generous or doing good," often describing a person's character or actions. Use "beneficent" for people who are charitable.
